2021 Tesla Model Y complaints

Vehicle can become difficult to steer in certain situations

Description of Safety Incident:The front passenger safety restraint system failed, displaying the warning alert: "Seats - Front passenger safety restraint system fault / Service is required." This alert disables or suppresses the front passenger airbag and seatbelt restraint system, creating a direct safety hazard for front-seat occupants.Service History & Recurring Defect:On February 26, 2025 (at 50,596 miles), Tesla Service Center diagnosed an open circuit in the front passenger seat harness/back frame. Under Service Bulletin / SRS Warranty, Tesla replaced the front seat back, seat harness assembly (PN: 1489060-03-G), occupancy sensor (PN: 1099592-00-F), and SBR sensor clip (PN: 1130363-00-B). On August 1, 2026 (at 63,583 miles)—less than 13,000 miles after the initial replacement—the exact same safety restraint system fault recurred.Safety Concern:The front passenger seat harness and Occupant Classification System (OCS) appear to suffer from design strain, pinching, or premature wiring degradation during normal seat movement. Because this defect disables critical safety restraint components and recurs shortly after replacement, I am submitting this report to request a federal safety review and investigation regarding Tesla Model Y front passenger seat wiring harness integrity.

Failure of the front lower lateral link and compliance link assembly. A creaking noise when steering at low speeds prompted me to take the vehicle to be checked out at a Tesla repair shop. The vehicle required a complete replacement of these parts at an independent cost of $1,900. I have the line-item proof of parts and labor.

I am reporting a safety defect involving a severe structural metallic "clank" or "clunk" under the vehicle's chassis during rapid acceleration and sudden braking. This vehicle was previously serviced by Tesla in 2023 for this identical issue (service invoice attached). While the repair initially suppressed the sound, the hazardous clanking noise subsequently returned, persisted for a period, and then went away on its own.The return and subsequent disappearance of the noise suggests that critical suspension or drivetrain components are shifting out of specification under load, binding, or experiencing intermittent mechanical failure. Given the active federal investigation into 2021–2023 Tesla Model Y front lower lateral link separations, I am deeply concerned that the underlying component remains structurally compromised despite the 2023 service. An intermittent or settling defect still poses an imminent safety risk of sudden component separation and total loss of steering control at driving speeds.

On June 7, 2026, my 2021 Tesla Model Y with approximately 37,131 miles became completely unresponsive and could not be driven. Tesla Mobile Service replaced the 12V low-voltage battery on June 11, 2026. The official repair notes stated that the battery was replaced, proper operation was verified, there were no active alerts, and the vehicle was in excellent condition. Shortly after this repair, multiple vehicle systems stopped functioning, including all cameras, navigation/GPS, and software/firmware updates. Tesla Service later diagnosed the vehicle as requiring replacement of the HW3 vehicle computer at a cost of approximately $3,066. The loss of camera functionality disabled or affected multiple driver assistance features that rely on the camera system. The vehicle has been unavailable for approximately one month while awaiting repair. During discussions with Tesla Service regarding the diagnosis, I was informed verbally by the Service Manager that they see similar HW3 computer-related issues on a regular basis (approximately every other week). I cannot independently verify that statement, but I am including it because it contributed to my concern that this may not be an isolated incident. I am not asserting the root cause of the failure. I am submitting this complaint because the loss of the vehicle’s camera system and related driver assistance functionality may represent a potential safety concern, and I believe NHTSA should be aware of this incident.

My 2021 Tesla Model Y (VIN: [XXX]) experienced a serious safety malfunction during a 12V low‑voltage failure. When the vehicle displayed the 12V alert, it became non‑functional. Upon entering, no systems were operating. When I pressed the brake pedal, the interior lights flashed and both front windows began moving up and down automatically without any input. This uncommanded movement caused both windows to shatter violently inside the cabin. The glass broke along the lower section of the window, consistent with internal mechanical stress caused by the window motor cycling during a fault. This was not external impact. I have photos documenting the breakage pattern. This is a safety defect. Automatic window movement during electrical failure poses a risk of injury. Additionally, even if a customer closes a door with the window raised, the glass should not shatter. Tesla vehicles are designed with automatic window indexing and motor resistance protection. The system should adjust the window position to prevent breakage. The fact that the glass shattered indicates a failure of Tesla’s safety logic and window indexing system. Tesla denied responsibility and claimed “misuse,” but could not provide system logs to support this claim. Tesla also stated customers must ensure windows are lowered before closing doors, but this requirement does not exist anywhere in Tesla’s manual. Tesla’s explanation does not address the automatic window movement that caused the breakage. This malfunctio

Within four months my car has suspension problems and I didn't know until my tires got bad there was a noise and I didn't know that was the suspension. I bought four brand new tires and I took it to the Tesla dealer and I told the attendant that my car was wearing the tire inside really bad. After I bought 4 brand new tires I took it to the Tesla for an alignment and when you left the car was even worse with the noise so bad. I am barely driving my car and I don't really know what to do if I have to take it to Tesla. I tried to get an appointment with Tesla and they are so full and my car feels like a rocking chair sometime. The tesla has only 31,000 miles.

High voltage battery pack failed. It is available for inspection. No one was affected by the issue when it occurred. Tesla has inspected it and stated it has imbalance, and entire high voltage battery pack needs to be replaced. Yes, there is a warning messages on the screen. (BMS_a079 - Unable to charge - Maximum charge level reached) ...but only shows 50% State of Charge The issue happened randomly while the car was parked yesterday 7/29/2026

This is for a recurring front passenger safety restraint system defect on a 2021 Tesla Model Y, VIN [XXX]. The defect has now resulted in at least six service visits or invoices involving the same front passenger restraint / occupancy system concern, and Tesla has now charged $1,582.18 for another repair involving the front passenger seat cushion trim and seat back trim even though prior repairs did not permanently correct the condition.

Hello, We have 46224 miles on the car currently. A couple of weeks back the whole battery died. Tesla replaced the battery and we picked up the car this past Friday, the XXX. After picking up the car the driver's seat does not slide. I looked it up online on the Tesla website as well as on the app and at both the places it was strongly recommended to bring the car back to Tesla as the problem was very very likely secondary to the battery replacement. the seat does not move at all. When I spoke to customer service at out local Tesla dealership in [XXX], the earliest date they could provide us was in the first week of August! This is an urgent issue. We happen to be away on vacation that week. So we were told to review the cost estimate and then find a date on the app to bring the car in. When I questioned the estimate price, I was told that this was the worst case scenario. But the invoice clearly states Calibration, and 3 prices for a switch package all amounting to $364.45 with tax!!! Again I questioned this huge charge, considering the battery replacement and I was told almost rudely, "That does not seem to be the issue." Just not right!!

My car is having issues with downloading the software and installing it. It usually happens during the summer. 2025 summer i booked an appointment and visited the Tesla Service center. They diagnosed and told me the ECU is having trouble and need to replace same. Its cost around USD 4K. My car faced this issue right after the warranty is over. First the High Voltage batter died next day the warranty got over, but they replaced it under Battery Warranty. But ECU issue they want me to pay for the same. Its a huge cost and i do see lot of customers keep complaining about the same/similar issues all over internet. It looks like a wide spread issue which Tesla ECU fail after the warranty get over. Biggest challenge for the customers are, No Navigation, GPS is not working, All the cameras goes blind, Lane assistant doesn't work. dashcam recording doesn't work. Technically we can just charge the car and drive. No safety features work as expected.

The electronic power assisted steering (EPAS) rack on my 2021 Tesla Model Y experienced an internal electronic failure. The failure first occurred while the vehicle was performing an automated parking maneuver (Autopark) at low speed. The vehicle displayed the warning "Steering assist reduced / Steering may require increased effort" (alert UI_a020_SteeringReduced). Using the vehicle's built-in Service Mode, I retrieved the underlying diagnostic fault: EPAS3P_a072_motFeedFwdError, described by the vehicle as "Motor control feed-forward correlation error," set when the difference between estimated motor torque and commanded torque exceeds 1.2 Nm. The vehicle's own diagnostic screen lists the clear condition for this fault as "Replace EPAS," indicating an internal hardware failure of the primary EPAS module. The listed potential impact is "Reduced steering assist and EAC inhibited." The fault initially cleared after approximately three minutes but returned and is now latched: it persists through vehicle reboots and multiple drive cycles. While the fault is active, power steering assist is reduced and lane keeping assistance / active safety steering features are inoperative. Safety risk: steering assist can degrade without warning during low-speed maneuvers, requiring sudden and substantially increased steering effort, and lane keeping assistance is disabled. The failure occurred while an automated driving feature was in control of the steering, with no curb impact, collision, or

Recurring front passenger safety restraint system fault causing incorrect occupant detection for airbag deployment. Failed and was ‘repaired’ 3 times since 2024, including 2 consecutive failed repairs of the same part within the last 3 months. Tesla service advisor also mentioned informally this is a common issue. Tesla is now refusing further no-cost repair despite both recent repairs remaining under Tesla’s own parts warranty.

Error ui_a020 "steering assist reduced" appears without any noticeable steering changes at the moment, but with a warning that steering may become increasingly harder and harder. There were recent recalls on other models of Tesla.

Safety features on vehicle stopped working after software update was pushed to my vehicle. GPS, all cameras including backup camera and ones used for blind spots, and cruise control have all stopped working. Time displays incorrectly due to GPS issue and night mode stays on so rear view & back window stay dark making it hard to see other vehicles around me during the day. I’ve followed all recommended steps to resolve and issue persists.

Tesla model y is experiencing a front passenger airbag sensor failure (OCS) covered by factory bulletin SB-23-20-002 alongside TMPS and EAEB alerts. Tesla corporate resolutions is refusing to fix these safety system failures with out charging $1400 out-of-pocket, citing warranty expired.

The steering is not functioning properly. This is sealed system and no where else I can get it. This a safety issue and I haven't seen any car steering failing like this. Even cars as old as 20 year has no such issues. This is huge slap on of $3k+ on consumer. The cars is hardly 5 year old.

2021 Tesla Model Y suffered a complete failure of the front lower lateral links, compliance links, and upper control arms at only 29,103 miles. The vehicle has been inspected by the manufacturer. It is currently being repaired at my cost. There was no warning lights or messages. I had noticed a creaking sound upon turning, especially while in reverse. I believe this mirrors the exact mechanical failures seen in NHTSA Campaign 21V835000. However, my VIN number was not listed in this recall.

* What component or system failed or malfunctioned, and is it available for inspection upon request? FSD. It is available upon request. * How was your safety or the safety of others put at risk? Over the course of the last two months since the last FSD update (currently on v12.6.4), at least 20 times the vehicle has not properly stayed in the lane under certain circumstances listed below. These circumstances are always the same and it is repeatable and dangerous as the vehicle would have crashed into the center median if I had not intervened. Repeatable conditions: * 79 MPH * Low curvature highway at highway speeds when turning to the right only. * FSD version 12.6.4 with software version 2026.14.6 is engaged and in Assertive mode. * Has the problem been reproduced or confirmed by a dealer or independent service center? Tesla wanted $1k in order to reproduce and diagnose the problem, so I declined. * Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Same as above; Tesla wanted $1k in order to reproduce and diagnose the problem, so I declined. * Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None of the safety systems fired, including lane departure warning or steering correction. FSD would not have veered out of the way of the median.

Backed-out LH Rear Lower Fore Link bolt causing structural elongation damage to the rear subframe mounting hole, requiring full subframe replacement. Vehicle had been serviced exclusively by Tesla. Tesla issued Service Bulletin SB-25-31-004 on April 17, 2026 covering this exact condition. Tesla declined to perform the repair under the bulletin citing out-of-warranty status. A touchscreen alert directing me to service was active at the time of denial.

We were trying to drive home and the middle seat belt, where my youngest child was sitting, would not latch. it would 'click' in, but if you pulled on it, it would pop out. This was terrifying because we had to drive home on a 2-lane highway with oncoming traffic. I checked online and found that many others have reported this issue because the seat belt latch sits rigidly upright in a divot in the seat, which acts as a funnel to direct any crumbs or dropped items to go into the seat belt latch, which then apparently causes the issue. This is a death trap design for children, because of course children drop things and make messes all the time, and applies to all three of the seat belt latches in the back. What is even worse about this issue is that as a parent I listen for the Click to know they have buckled, and I also check the seat belt indicator on the dash screen. Even when this model Y seatbelt latch isn't going to hold the seatbelt in place, it makes the Click sound and also shows as latched on the dash screen, giving parents a false sense of security. It looks like no children have been injured or killed yet because of this design flaw, but please do not wait for that to happen. Please make them fix this issue immediately before tragedy strikes a family. Please watch the video I linked to in the PDF to see how the seatbelt clicks into place, but then can be pulled free by a firm tug on the seatbelt.

I am submitting this complaint to request an investigation into a serious safety defect involving my Tesla vehicle. On multiple occasions, the vehicle has experienced a significant and unexpected loss of acceleration when I attempted to enter or cross intersections. Despite pressing the accelerator, the vehicle failed to respond as expected, leaving me unable to accelerate normally while entering active traffic. This is not a minor hesitation or inconvenience. It is a serious roadway safety hazard. Drivers rely on immediate acceleration when crossing intersections, turning across traffic, or merging. A vehicle that unexpectedly limits acceleration can place occupants directly in the path of oncoming vehicles, creating a substantial risk of a severe collision, serious injury, or death. I reported this issue to Tesla Service and provided multiple timestamps documenting the events. Tesla was unable to identify any fault codes or provide a diagnosis and indicated that because no fault was recorded, the issue could not be confirmed. Through independent research, I found numerous reports from other Tesla owners describing substantially similar acceleration limitation events. Many reports specifically reference Obstacle Aware Acceleration as a possible cause, and some owners report that disabling the feature resolved the issue. If a safety system can falsely detect an obstacle and reduce acceleration while a driver is actively entering an intersection, the system itself may create a

A 2021 Tesla Model Y experienced steering/suspension warnings followed shortly by a steering-assist reduction event. On or around May 21, 2026, the vehicle displayed: “Steering alignment service recommended — OK to drive, schedule service soon.” The vehicle was brought to Tesla because the owner was concerned the car had detected a steering, alignment, suspension, or safety-related condition. The Tesla invoice from that visit appears inconsistent. It states that “a wheel alignment check was completed,” but also states “No Labor Performed — Customer Did Not Authorize Repairs or Inspection,” with 0.00 labor hours and no charge. A documented steering/suspension diagnostic inspection, alignment report, alert-log review, or safety assessment was not performed by Tesla or inspected. The owner was advised to replace tires and return later. Approximately 90 miles later, during a low-speed three-point turn, the vehicle made a loud pop/clunk from the front area and displayed: “Steering assist reduced — Steering may require increased effort.” A related alert also stated Lane Departure Avoidance features were unavailable. This created a safety concern because steering effort may unexpectedly increase during low-speed turns or parking maneuvers. Tesla later inspected the vehicle and documented torn front lower lateral/compliance link bushings and vehicle log data showing steering gear alerts. Tesla replaced the front lower lateral links and front lower compliance links and performed align

The vehicle’s secondary Autopilot Processor / car computer is internally faulted and stuck in a continuous wake/shutdown loop. This causes severe standby battery drain (~20 miles of range lost per day while parked) and completely prevents all over-the-air software updates - including federally mandated safety recall remedies. On April 4, 2024, Tesla Service diagnosed the fault and linked it to the drain and inability to update. On the same visit, Tesla added two safety recalls (23V-838 Autosteer controls and 24V-051 Brake/Park/ABS indicators) to the work order. They then demanded ~$3,000 customer payment for computer replacement before the recalls could be performed. After I declined the paid repair, Tesla marked both recalls as “completed” via software update despite the same invoice stating the vehicle could not receive updates and remained on software version 2023.38.9 (which predates both remedy firmwares they claimed was installed). Tesla is effectively paywalling federally required safety recall remedies by requiring the customer to first pay for computer replacement first. Two additional recalls remain open (21V-389 seat belt fasteners and 24V-554 hood latch). The problem has been confirmed and documented multiple times by Tesla Service.

Even after the recent recall for backup camera freezing, my backup camera froze again today. I took the car in, in the past, to report the problem and was told to reset the computer even after the technician witnessed the problem. Got charged $300 so haven't been back. Problem has been there for a couple of years. I had hoped the software update would fix it but no such luck.

My 2021 Tesla Model Y experienced a critical failure resulting in the vehicle displaying diagnostic code BMS_079. After the fault appeared, I was informed that the vehicle's High-Voltage (HV) Battery requires replacement at a cost exceeding $10,000. As a result of this failure, the vehicle is no longer drivable and has been effectively rendered unusable. The High-Voltage (HV) Battery Management System and/or HV battery pack failed, triggering Tesla diagnostic code BMS_079. The vehicle is currently unable to operate due to this fault. The vehicle and battery system are available for inspection upon request. The sudden failure of the HV battery system created a significant safety concern because the vehicle lost its ability to operate as intended. A battery failure can leave drivers stranded unexpectedly, potentially in unsafe locations such as highways, intersections, remote areas, or during adverse weather conditions. The inability to reliably operate the vehicle creates a safety risk for both occupants and other motorists. The fault code BMS_079 was diagnosed and confirmed through Tesla's service system. Tesla service personnel indicated that the HV battery requires replacement and that the vehicle cannot be driven safely until the repair is completed. Prior to the vehicle becoming inoperable, warning messages appeared on the vehicle display indicating a problem with the battery system. The BMS_079 fault code was displayed, and the vehicle subsequently restricted operation.n

I purchased a 2021 Tesla Model Y (VIN: [XXX] ) used directly from Tesla. I am the first retail owner outside of Tesla. I am currently experiencing a knocking noise from the driver side suspension. I have requested that Tesla inspect and complete the following federally mandated safety recalls and service bulletins, none of which appear in my vehicle’s service history: • NHTSA Recall 21V-835 / SB-21-31-003 — Front suspension lateral link fasteners may loosen and separate from the sub-frame, causing instability and crash risk • NHTSA Recall 21V-912 — Suspension knuckles may fracture • SB-20-31-006 — Front upper control arm ball joint reseal Tesla service has refused to perform these repairs free of charge, citing expired warranty (warranty expired April 5, 2025). Tesla’s response does not address that these are federal safety recalls, not warranty repairs. Federal law requires recall repairs to be performed free of charge regardless of warranty status, age, or mileage. Tesla has also failed to provide written documentation confirming whether these recalls were completed prior to selling me the vehicle. Instead, I have been redirected to a self-service VIN lookup tool and a general data privacy request form — neither of which confirms when, where, or whether the recall work was actually performed. I am requesting NHTSA investigate Tesla’s failure to complete these safety recalls prior to selling this vehicle to a retail customer, and their refusal to honor federal recall obligat

This incident is related to Full self driving feature in my Model Y. It abruptly stopped on the road even when there was no obstacle. Luckily there were no vehicles behind my car which would otherwise resulted in accident and injuries to myself and my family.

While my vehicle was operating under FSD, it ran a red light at the above intersection, resulting in an accident.

Phantom brake incident today,5/26/26. Traveling 35mph, brakes slammed on for no apparent reason. Seatbelt tightened and my head launched forward. Neck is very strained.

Component that failed: Front lower lateral link and compliance link suspension bushings. Failed components were removed by Tesla Service and are no longer available for inspection. Safety risk: Failed suspension bushings directly compromise steering precision, vehicle stability, and handling — particularly at highway speeds. A driver unaware of this failure could experience loss of steering control or unpredictable handling without warning. Confirmed by dealer: Yes. Tesla Florida (Tampa, 11945 North Florida Avenue) confirmed the failure in writing on May 22, 2026. Technician repair notes state: “inspection failed due to worn suspension bushings in the front.” Tesla confirmed this was the first time these original components had ever been serviced. Invoice #[XXX]. Manufacturer inspection: Yes, repaired by Tesla Service Center. Cost: $1,669.58. Warning lamps or prior symptoms: None. No warning lights, no alerts through the Tesla app, and no prior symptoms communicated to the owner. Failure was discovered only because vehicle was brought in for an extended service agreement inspection. Assessment: Original factory suspension bushings completely disintegrated at 56,258 miles on a 2021 Tesla Model Y (VIN: [XXX] ). This is not normal wear — photographic evidence shows full structural disintegration of rubber bushing material. Other Model Y owners may be driving with identical failures without knowledge.

I am reporting two unresolved safety-related defects on my 2021 Tesla Model Y (VIN: [XXX] ) that occurred following paid service at Tesla's League City Service Center on 04/16/2026 DEFECT 1 — COMPUTER AND SENSOR SYSTEM FAILURE: The vehicle's onboard computer cuts in and out intermittently. Sensors fail during operation and the problem worsens significantly in high-temperature conditions. Tesla vehicles rely on their computer and sensor systems for core safety functions including collision avoidance, autopilot, and driver assist features. Intermittent failure of these systems while operating the vehicle is a safety hazard to the driver and the public. DEFECT 2 — GLOVE BOX INOPERABLE: The glove box does not open following Tesla service. The glove box in Tesla vehicles houses key vehicle documentation and is integrated into the vehicle's locking and security system. I paid $2,497.50 for service on [06/16/2026]. Both defects were either caused or left unresolved by that service. I have notified Tesla service staff directly and followed up multiple times over more than four weeks. Tesla has not responded, has not scheduled any repair, and has not refunded my money. I am filing this complaint because (1) the sensor and computer failures present an active safety risk during operation, (2) Tesla has ignored all attempts to resolve this, and (3) public reviews indicate this is a pattern affecting multiple consumers. I request that NHTSA investigate and determine whether a safety defec

The vehicle’s low-voltage battery system failed unexpectedly, causing a complete loss of electrical power and preventing normal vehicle access and operation. The failure resulted in my [XXX] child becoming trapped inside the vehicle. The malfunction appears related to the 12V/low-voltage battery and/or associated power management system. The vehicles inspection invoice is available upon request. This incident created a serious safety risk because the loss of low-voltage power prevented normal door operation and immediate access to my child. The situation posed risks of heat exposure, medical distress, panic, and delayed emergency access. Although the vehicle includes a manual emergency door release, it is not realistically accessible or operable by a baby or toddler secured in a child safety seat. A young child cannot reasonably be expected to understand, locate, or operate the manual release during an emergency. The sudden failure without warning left my child unable to exit independently while caregivers were temporarily unable to access the vehicle. There were no noticeable warning, messages, or other symptoms prior to the failure. The low-voltage battery appeared to fail suddenly and without sufficient warning, resulting in immediate loss of access and vehicle functionality. The problem has not yet been reproduced, but the low-voltage battery failure was identified after the incident. The vehicle has been inspected by Tesla service. No formal police or insurance inspectio

My 2021 Tesla Model Y HW3 experienced complete failure of all cameras, GPS, Automatic Emergency Braking, and Adaptive Cruise Control following the installation of software update 2026.8.6.1 — the OTA remedy update issued by Tesla for NHTSA Recall 26V283000. The vehicle was fully functional prior to this update. The failure was confirmed and reproduced by Tesla's authorized service center. The service advisor confirmed in writing: "During the update, the computer failed to reboot properly. We attempted to perform a 12V reset but unfortunately it is still stuck in the boot loop state." The Autopilot ECU (Primary/Turbo A) is stuck in a permanent boot loop and cannot be recovered by software means. Safety impact: All cameras including rearview camera are completely non-functional. Automatic Emergency Braking and all ADAS features are disabled. The vehicle cannot safely detect obstacles or pedestrians. GPS navigation is frozen. Tesla has confirmed the computer requires replacement but is classifying it as a customer-pay repair citing expired warranty, despite the failure occurring during Tesla's own recall remedy software deployment. This vehicle meets every technical criterion of Recall 26V283000 — HW3 hardware, 2021 Model Y, software version 2026.8.6.1, complete camera failure — but does not appear in the recall VIN database. I am requesting NHTSA review whether this VIN should be included in recall 26V283000 or a related investigation.

The vehicle began experiencing repeated Autopilot/FSD failures while driving. Symptoms included sudden Autopilot disengagements, cruise control becoming unavailable, and loss of road visualization/navigation display functionality. The issue progressively worsened over time. The vehicle was first brought to Tesla service in 2025 for the same overheating-related concern. At that time, Tesla identified a coolant-related issue, topped off the coolant system, and returned the vehicle to service. However, the problem continued and gradually became more frequent and severe afterward. During the most recent service visit, Tesla diagnosed the HW3 Autopilot computer as overheating due to a heat transfer failure between the Autopilot board and cooling cold plate. Tesla stated that heat generated by the board could no longer be efficiently transferred to the coolant system, causing the Autopilot computer to overheat. Tesla further advised that continued operation without repair could eventually impact additional vehicle functions, including the center display screen shutting off due to overheating-related failures. Given the loss of driver-assistance functionality and potential impact to core vehicle systems, I am submitting this report so the issue is documented as a potential thermal management or hardware reliability concern involving the HW3 Autopilot computer system.

My 2021 Model Y has about 24,500 miles began squeaking when turning the steering wheel or hitting bumps. I read online that many tesla owners had the same issue. The design on these weren't great allowing water to penetrate these parts and cause them to ware down faster. I already paid for the replacement of the upper and lower control arms.

While traveling at approximately 80 mph with Full Self-Driving (Supervised) engaged, my vehicle experienced a simultaneous failure of the Full Self-Driving computer and the Media Control Unit (MCU) touchscreen. Without any prior warning, the touchscreen went completely black, and the vehicle immediately executed an uncommanded, sharp steering maneuver into the right lane. It was very apparent that if I didn’t take over it was going to continue crossing highway lanes and go off road. I have around 45k miles specifically on FSD and never has it failed in such an extreme manner. This sudden steering input put myself and other motorists at extreme risk of a high-speed collision or roadway departure. I was forced to physically overpower the steering wheel to maintain lane integrity and prevent a crash at highway speeds. The failure appeared to be a total loss of the vehicle’s primary visualization and automated steering systems, leaving me with no digital feedback regarding speed or surrounding traffic while the car was still in motion. Prior to this event, there were no warning lamps or symptoms such as GPS drifting or screen lag. I have since attempted a hard reset and a full power cycle, but the critical nature of this uncommanded steering at 80 mph suggests a systemic defect in how FSD manages hardware or software failures. The vehicle and its internal data logs are available for inspection upon request. This incident has been documented in the Tesla App under a service reques

The rear camera has failed posing a safety issue when reversing the vehicle.

Incident Date: April 11, 2026 Approximate Time: 6:30 PM Component(s): Unknown (Suspected: Electronic Stability Control, Steering, ADAS) Description of Incident: On April 11, 2026, at approximately 6:30 PM, I was operating my Tesla Model Y on a highway with a self-driving mode engaged. I experienced what appeared to be a sudden, unintended acceleration combined with an erratic "zig-zag" steering pattern across multiple lanes. I am not certain of the technical cause, but the vehicle’s behavior felt like a loss of system control that was not initiated by me or the road conditions. I had to intervene immediately to prevent an accident. Post-Incident Actions and Manufacturer Contact: I have since contacted Tesla Service, and while they confirmed that data for that date exists, my formal "Privacy Data" requests for those specific logs have come back empty or missing the relevant timeframe. Summary of Concern: I am reporting this because I suspect a serious software or hardware malfunction occurred, though I do not have the technical diagnostic to confirm which system failed. The combination of the vehicle’s erratic movement and the subsequent difficulty in obtaining the data logs for this specific window of time leads me to believe there is a potential safety defect that requires investigation.

The paint on my Tesla Model Y is peeling and delaminating along both sides of the rear trunk/hatch seam, adjacent to the rear glass. The issue appears in the same location on both sides in a symmetrical pattern. There has been no accident, impact, or external damage to these areas. The peeling began gradually and has continued to worsen over time. The symmetry and location suggest this is not normal wear or environmental damage, but a potential defect in paint adhesion or manufacturing at the trunk seam. This condition exposes underlying material and may lead to further deterioration, including corrosion over time. I am reporting this as a potential manufacturing defect affecting durability of the vehicle exterior

**What component or system failed or malfunctioned, and is it available for inspection upon request?** The vehicle experienced a critical failure immediately on the same day of purchase, rendering it not functioning or inoperable. It was deemed to be preexisting from the dealership I bought it from. The battery is malfunctioning affecting the driving capacity and range. --- **How was your safety or the safety of others put at risk?** The failure created a significant safety concern, as the vehicle was not operating reliably immediately after purchase. This placed me at risk of being stranded and potentially exposed to hazardous conditions, including loss of transportation in unsafe or uncontrolled environments. Or stopping while driving. --- **Has the problem been reproduced or confirmed by a dealer or independent service center?** The issue was immediately reported to the dealership, and they acknowledged the problem by agreeing to an exchange of the vehicle due to its defective condition. It was confirmed by a service center of the car's manufacturer. --- **Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?** At this time, the vehicle has inspected by the manufacturer. --- **Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?** Yes, although the manufacturer can't pinpoint when they started but said they had been on since ATLEAST March 10. My

Squeaking (lubrication failure) of the front suspension components, prematurely, are a common and widespread issue with Tesla vehicles. I have approximately 60k miles on my model Y and the front control arms are making noises. Tesla wants to replace a significant amount of suspension components at a high cost, instead of a recall (or creating serviceable lubrication points on these components). The NHTSA needs to hold Tesla accountable for faulty suspension design and lack of maintainability leading to premature failure.

The back drivers side seatbelt belt does not latch. The manufacturer refuses to fix without a fee.

Getting message on screen since october 2025. That time total milage on my car was less then 30,000 STEERING ASSIST REDUCED and LANE DEPARTURE AVOIDANCE FEATURE UNAVAILABLE. I did reset / restart the vehicle / soft / hard reset, software update. and This both message got disappear and then again after sometimes its keep coming back. So i did appointment to rocklin tesla center and they gave me cost estimate $5770. Thats way too much so i decline but they said those message might keep popping up because of LOW VOLTAGE DISTRIBUTION AND CONTROLLERS. So i accepted that service and paid $359.68. But i am still getting same both messages on my tesla screen. Sometimes it does comes and sometimes it does not. I did online research and people with same problem stating that because of TESLA's poor manufacturing steering wheel and some kind of faulty circuit board causing this issue. My car never been to any accident and its very low on milage. Please look for other tesla owner who has same problem and tesla has to fix this problem without charging this much amount. Thanks

I was entering the on-ramp to [XXX] , from [XXX] , to merge onto the freeway east bound towards [XXX] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [XXX] and [XXX] . We were completely trapped in the vehicle with no power. My [XXX] old remembered to use the manual latch to get out. I opened my door manually and It broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [XXX] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this.

While on my way to run an errand, I opened up the back door to strap my 2 year old in, when i closed the door, the car would not open whatsoever, after trying for a few minutes with the phone key app for tesla and the physical key fob, nothing would work. I had to end up calling 911 and firefighters came out and had to physically open the door, which broke the window. The car was completely unresponsive and would not turn on. After researching what happened, it turns out the 12v battery had died. I was able to jumpstart the car with jumpers and that was able to open up the rest of the car's doors. However, during the time my son was stuck inside with the over 95 degree weather, the had no safety mechanism in place to open it physically like a traditional key fob would. It is very disheartening knowing my son could have potentially lost his life over something so simple that could be resolved with a physical keyhole on the outside like almost every traditional vehicle has. This is something that should not occur, ever. The fact that the car was able to open up once more before completely dying and perfectly at the wrong time after closing the door while my son was trapped in there in complete heat was very disappointing.

I own a 2021 Tesla Model Y with approximately 46,500 miles. The vehicle is currently displaying battery error code BMS_a079, and the battery will only charge to approximately 30%, which severely limits the driving range and makes the vehicle unreliable for normal use. I reported this issue to Tesla on March 6, but the earliest service appointment available to me is March 17 at the Tesla service center in Fayetteville, Georgia. Because Tesla service centers are not widely available, I must travel to another city to have the vehicle inspected. The limited battery charge creates a difficult situation because I must determine how to get the vehicle safely to the service center with very restricted range. I may have to arrange towing or attempt to drive a vehicle that cannot fully charge. This issue has also created a hardship for my household. I have a toddler and normal daily responsibilities, including errands and transportation needs, but the vehicle cannot reliably be used due to the charging limitation. Being without dependable transportation for an extended period of time places families like mine in a very difficult position. This problem appears to be related to the vehicle’s battery management system and is not the result of driver misuse. Consumers should not be placed in situations where a major battery fault leaves them with limited transportation options while waiting extended periods for service, especially when service centers are not easily accessible.

Vehicle will suddenly apply brakes while using standard cruise control for no apparent reason. This is extremely dangerous as it has almost caused several accidents on the highway. I have almost been rear-ended several times. This is a very common problem and well documented problem referred to as "phantom braking" on Teslas and something needs to be done immediately.

The vehicle's Autopilot/Full Self-Driving (HW3) computer has failed at approximately 70,000 miles. Tesla Service has diagnosed the vehicle as requiring replacement of the HW3 computer. As a result of this failure, multiple safety related systems are inoperative, including collision avoidance, lane assist, lane departure warning, automatic wipers, and other driver assistance features including adaptive cruise control. The vehicle is also unable to receive over-the-air software updates, including potential safety updates. In addition, the vehicle experiences system lag, including delay when shifting into Drive or Reverse. The center display is slow to respond, and certain media and software features are no longer functional due to inability to update. This condition increases safety risk because active safety systems designed to assist with collision prevention are disabled. The failure appears to be hardware-related and not due to normal wear. Tesla has confirmed the need for computer replacement but has declined coverage as the vehicle is outside warranty. The failed component should be available for inspection upon request.
