2021 Tesla Model Y complaints

The car suddenly reduced lane assistance and steering assistance functionality. After calling Tesla they said it is not a software issue. I checked the service mode and it indicated a malfunction in the steering assist motor, which apparently costs $3500 to replace. Online, I have found many complaints about this problem that are not resolved by software updates. In addition, there was a large number used steering assist motors for sale online which indicates a more wide spread problem. This is not normal for cars to have this failure prematurely and is a serious safety hazard. I read online that some had their steering EPAS get locked while driving on the highway and nearly destroyed their Teslas

Vehicle experienced front suspension lateral link failure. The links separated from the sub-frame due to improperly secured fasteners. This is the exact defect described in existing recall SB-21-31-003 / NHTSA Campaign 21V835000. The existing recall states 'front suspension lateral link fasteners may loosen, allowing the lateral link to separate from the sub-frame.' This vehicle has this identical manufacturing defect but was not included in the recall database. Tesla Service confirmed the links 'fell out' and separated from the sub-frame at approximately 65,000 miles. Technician notes indicate a 'speed mismatch between wheel and motor' caused by the link separation - this is the symptom of the underlying fastener defect. The failure resulted in loss of steering control and made the vehicle undriveable (VOR - Vehicle Off Road). This is a safety-critical manufacturing defect affecting front suspension, creating crash risk due to sudden loss of vehicle stability and control. Owner is being charged for repair of a known manufacturing defect that should have been covered under the existing recall. This suggests the recall scope was too narrow and did not capture all affected vehicles with this defect. Request investigation into whether recall should be expanded to include additional affected vehicles.

Front subframe and both front lateral links came loose due to welded nut not present

The upper control arm bolt came loose on its own.

Received a notice that steering assist may be reduced. Other model year Ys have been recalled due to the same issue. It doesn’t make sense that this should fail in a vehicle that is 5 years old with no accidents and low mileage. This is a safety issue due to manufacturing defect and should be covered under warranty.

On [XXX], after placing my young child in my Tesla and closing the door, the 12V battery failed suddenly and the vehicle became inaccessible. I was unable to unlock or enter the car. I did not receive any warning or alert that the 12V battery was about to fail. The vehicle was in my garage, and the window automatically cracked, which allowed me to monitor my child while I sought help. I called Tesla Roadside Assistance at 8:59 AM. During the call, the representative reassured me that help was being dispatched and at times described the service provider as “on the way” (timing details such as “within ~45 minutes” and the length of the initial call are my best estimates). After continued waiting with my child confined inside the vehicle, I contacted emergency services due to the safety risk. I called 911 at 10:03 AM. I later had the 12V battery replaced at my own expense. This incident involved a sudden electrical failure without warning that resulted in a child being trapped inside a disabled vehicle, and I am also concerned about the accuracy and effectiveness of roadside assistance dispatch communications during the incident.

When driving with cruise control engaged the car randomly brakes and shows a "curvature assist " indication. The car quickly slows from 55 to 35 with no warning. This primary happens on a straight road, not a curve. I am concerned about the traffic behind me.

Lower front control arms are bad. Was told by tire company they need replaced. Quote about 2k

There is a rip in the lower control bushing making steering difficult to control. I see that this is a common issue but no recall yet. My car has only 28k miles.

The contact's client owned a 2021 Tesla Model Y. The contact stated that while his client was driving at an undisclosed speed under 60 MPH, the vehicle caught fire in an unknown location. The origin of the fire was unknown. The contact stated that his client attempted to unlock the vehicle doors, but the driver's handle did not work as intended, trapping the contact's client in the burning vehicle. The contact stated that the police and fire department arrived, but were not able to get close enough to the vehicle due to the inferno. The contact's client succumbed to the fire. The fire department extinguished the fire after approximately 40 minutes. The vehicle was destroyed but towed to a tow yard. The manufacturer was notified of the fatality. No further information was available as of yet. The failure mileage was unknown.

My heat pump and ac unit went out and Tesla wants me to pay $4000 for a faulty part that broke in less then 3 years

After charging the vehicle threw error code “BMS_a079 Unable to charge - Maximum charge level reached Reduced maximum charge level - Schedule service”. The car would no longer charge and had to be taken in for service. Tesla advised the High Voltage battery needed to be replaced. Replacing the High Voltage battery resolved the issue.

I parked my Tesla vehicle in a friend’s driveway. When I returned and opened the driver’s door, I entered the vehicle and attempted to put it into Drive. At that point, the vehicle display went completely blank and the vehicle became inoperable. I then attempted to open the door from inside the vehicle, but the door would not open and I was unable to exit the car. I was effectively locked inside the vehicle. I contacted Tesla customer support and remained on the call for approximately 1.5 hours before receiving assistance. Tesla customer support confirmed that the issue was caused by failure of the 12-volt battery. At the time of the incident, the outside temperature was below 0 degrees centigrade. The incident occurred in Cedar Rapids, Iowa. There was no prior warning or notification from the vehicle or the Tesla mobile app indicating that the 12-volt battery was at risk of failure. The failure resulted in loss of vehicle function and inability to exit the vehicle, creating a serious safety concern.

I noticed the windshield washer nozzle on the passenger side isn't either working or not there. I reached out to Tesla, and also stopped by a Local Dealership and they told me that it would cost me out of pocket, since it's out of warranty. Secondly, the left side driver repeater camera has a Glare when turned at night time only. which is quite dangerous due to very less visibility due to the Glare of the Turn signal light that causes the repeater camera to function properly. this is a on going known problem. I have reached out to Tesla for this matter. and I was advised that it would not be covered since it's not under warranty. This issue should be a recall that Tesla should fix. this isn't an issue caused by normal wear and tear it's a manufacturer defect.

On Monday 12/29/2025, while driving my 2021 Tesla Model Y on the highway at approximately 70 mph returning from DTW Airport to my home with my children in the vehicle, the steering suddenly locked / the steering wheel would not turn. I was able to pull over to the shoulder. There were no warning lamps or warning messages displayed before or during the failure. After pulling over, I powered the vehicle off and back on. The steering partially worked again, and I was able to drive home. Later the same day at my friend’s house/driveway, the steering locked out again and this time it was completely locked, making the vehicle not safely drivable. Again, there were no warning messages or symptoms prior to the lockout. Tesla Service provided a written estimate documenting the complaint “steering locked out / cannot drive” and proposed replacing the steering gear/steering rack (“Steering Gear LHD,” part number 1188832-00-B) plus alignment, total about $3,127.70, at 96,042 miles. The vehicle and component are available for inspection upon request (Tesla can retain the replaced part). This is a safety defect concern because sudden loss of steering control on a highway without warning could lead to a crash, especially with passengers/children in the vehicle.

Both front half shafts failed and had to be replaced by Tesla. I did research and this part is known to be substandard, was recalled in China, and remains a problem in the US.

The contact owns a 2021 Tesla Model Y. The contact stated that while the vehicle was parked, the contact observed the code BMSA079 on the computer, and messages "Vehicle Unable to Charge to Maximum Charge Level" and “Maximum Charge Level Reached - Reduced Maximum Charge Levels" were displayed. The vehicle was taken to a dealer, and it was determined that one coil in the battery was inoperative, and the dealer reduced the charge and refused to increase the battery charging level. The manufacturer was notified of the failure. The failure mileage was 155,000.

The vehicle’s high-voltage battery and charging system experienced repeated failures, preventing charging while the vehicle was parked. This issue occurred three times: January 2024: Charging error “BMS_a079. Unable to charge” appeared. Vehicle was stranded and required service intervention. Mileage ~28,125. November 2024: Same charging error during winter travel, vehicle stranded mid-trip, creating safety risk for passengers. Mileage ~38,744. September 2025: Charging error recurred mid-trip, vehicle had to be left at a service location. Mileage ~48,918. All incidents were reported to Tesla under battery warranty. Repairs were attempted each time, but the problem recurred. A repurchase request was submitted after the third incident and was denied, with only a goodwill service credit offered. Safety concerns include the risk of being stranded, particularly during long trips or in winter conditions, which could affect passengers and other road users. The battery and charging system were inspected by Tesla service personnel after each incident, and the failure was confirmed each time.

Picked up car from tesla service on 12/30/2025. On [XXX] at around [XXX] I had pressed the car break and suddenly accelerated and lead to crashing into the pole. I am concerned about the safety and if it is drivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In May 2025, Tesla pushed an over-the-air (OTA) software update overnight while the vehicle was parked. When the vehicle was started the following morning, the update had failed mid-process and stalled at approximately 50%. Immediately upon startup, the backup camera and navigation/maps stopped functioning. The vehicle has been unable to complete subsequent software updates since. Tesla service later inspected the vehicle and indicated that the main computer/ECU was stuck in a loop and required replacement. The backup camera and navigation loss occurred immediately following the OTA update and persisted for several months despite multiple service attempts. Due to the vehicle’s rear design and limited rear window visibility, operating the vehicle in reverse without a functioning backup camera significantly impairs visibility. Even when using mirrors or physically turning to look backward, rearward visibility is restricted. As a result, the loss of backup camera functionality presents an ongoing, daily safety hazard during normal vehicle operation.

In early Nov 2025 my Tesla Model Y began intermittently showing warnings about the forward collision warning system and multiple sensors being offline. Tesla service replaced a faulty connector on Nov 3. On Nov 15, 2025, about two weeks later, the car had a sudden drivetrain failure while I was parking on a steep hill. I heard a loud bang from the front of the car and the vehicle immediately lost drive power and had to be towed. Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12V battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “VCFRONT offline/unable to contact VCFRONT” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12V failure and says the overheating was due to an air pocket in the cooling system, but the VCFRONT messages, inconsistent regen braking, a

I am filing this complaint regarding a high-voltage battery defect in my 2021 Tesla Model Y. The vehicle has been diagnosed by Tesla Service, and both the technician and service advisor confirmed that the high-voltage battery has an internal short. This is a critical failure involving the primary energy/storage system of the vehicle. Despite acknowledging the internal failure, Tesla is denying warranty coverage for the battery replacement. They have stated that failure is internal, and is not caused by anything external The failure was not caused by an accident, environmental exposure, or improper use. This appears to be a component-level defect within the 2021 Tesla Model Y battery packs Considering Tesla has issued prior service bulletins for Model Y high-voltage battery quality issues in adjacent model years, this may indicate a broader pattern of battery defects. They are trying to charge people over $12,000 for battery replacements that should be covered by tesla due to poor workmanship and materials used. Many have had to have multiple battery packs replaced.

Frunk (Hood) has been randomly opening at times when the car is parked. Today it opened after being parked at my office parking lot for 3 hours. I am concerned that this can occur while driving, especially on the highway, potentially causing a deadly accident.

Tesla's Full Self Driving (FSD) stopped my car on trolley tracks today, and would have stayed on the tracks for a minute if I hadn't taken control and driven off the tracks. This occurred in downtown San Diego, where the trolley (light rail) has many level street crossings. They are well marked. You are not supposed to enter the zone around the tracks until the vehicle ahead of you has moved far enough for you to be able to cross the tracks and get safely past them. I was using FSD. It drove my Tesla onto the tracks before the car ahead of me had given me room to get off the tracks. The line of traffic was stopped for a red light. I would not have been able to drive forward until the light changed, perhaps over a minute. So, I took over and manually drove the car into the adjacent lane, which luckily was empty, and off the tracks. If a train had come while FSD was still in control, this would have killed me, and perhaps other nearby people. There was no warning message or other indicator.

Left rear passenger seatbelt stopped working. There are no visible issues with the belt, metal plug or receptacle, but for some reason the seatbelt will not engage nor click in to secure the belt onto the passenger. This is a safety issue as my daughter typically sits in this seat and she cannot safely sit there now without a functioning seat belt.

The car has a feature called "curvature assist" that takes control of braking and steering at times when using cruise control. The incidents are at times surprising as there is no curvature present but the braking is suddenly applied. This is a surprise for both the driver and any following traffic. The car would be safer if this feature could be disabled but that is not possible.

Detailed Description of the Defect: Friday Incident: While picking up my son from school, the vehicle abruptly disabled multiple safety and driver-assist features. The car rolled backward on a slight incline, failed to display any surrounding vehicles on the FSD visualization, and retained accelerator input even after I removed my foot from the pedal. The vehicle continued to speed up slightly in Drive and Reverse without my input. Soft resets did not resolve the issue. Monday Incident (Collision Caused by Malfunction): On Monday morning, the same malfunction occurred. As I reversed into my garage with the door opening, the car again held the accelerator input after I lifted my foot, causing the vehicle to continue moving backward unexpectedly. The vehicle struck my garage door, causing property damage and a dent to the trunk. This was not driver error. It was unexpected propulsion after pedal release — an extremely dangerous condition.

The front suspension on my 2021 Tesla Model Y developed progressive creaking and groaning noises during low-speed turning, especially in parking lots or when maneuvering. The noise began intermittently around 45,000 miles and became much louder by around 86,000 miles, which made me concerned about a potential safety issue before a long family trip. The sound comes from the front lower suspension area and indicates that something may be loose or failing. I am worried about the possibility of losing steering control if the suspension components separate or shift while driving, especially with my children in the car. The Tesla Service Center in Lisle, Illinois inspected the vehicle and informed me that both front lower lateral links and both front lower compliance links must be replaced (all four front suspension links). The repair estimate is about $1,600. This problem appears identical to the condition described in Tesla’s campaign/recall SB-21-31-003 / NHTSA 21V835, which involves improperly torqued front lower lateral link fasteners on 2020–2021 Model Y vehicles. My vehicle shows identical symptoms and identical components, but my VIN does not appear in the recall. I contacted Tesla corporate support by email requesting a safety/goodwill review, but I have not received any response. I believe this issue is safety-related and may indicate that more vehicles should be included in the existing recall. I am attaching the Tesla service diagnosis confirming the required replacemen

I dropped my kids to school and started reversing the car without seatbelts. Thinking that I will get out of the parking lot and then put the seatbelt on. Car will stop and goes into park mode. Somehow I came out of the parking lot and about to put and drive again same thing. Car will go into park mode. Somehow I started coming out of the parking lot and took a pause. Same thing again car stops and goes into park mode. It was almost the car behind me about to hit. I guess this is a bug of the “Hold” mode.

My 2021 Model Y at 49,865 miles had a safety-critical failure of the "front lower compliance and lateral links." The Tesla technician confirmed it was a "safety issue."

The contact owns a 2021 Tesla Model Y. The contact stated that while driving uphill at an undisclosed speed, there was an abnormally loud pop coming from the vehicle. No warning light was illuminated. In addition, the contact stated that the vehicle lost automotive power and rolled away in reverse downhill towards oncoming traffic. The contact was able to avoid oncoming traffic and reverse onto the shoulder of the road; however, the driver’s side rear driver’s door failed to unlatch or open as intended while using the interior door handles. A local tow truck arrived on scene, and the passenger’s side door failed to open as intended with the exterior door handle. The vehicle was towed to a local dealer, where it was diagnosed, and determined that the 12-Volt battery needed to be replaced. The vehicle was repaired but remained at the local dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.

This incident appears to relate to NHTSA ongoing investigation at Tesla's low voltage battery system failure causing door handle malfunction. (September 26, 2025) 2021 Model Y front and rear doors (all four) was locked down with a seven years old child inside the car at home garage driveway. Mom unable to open up doors from exterior. A few hours later, left driver door was able to open but other passengers door remained locked down. (October 2, 2025) Sent Model Y to Tesla service center and identified low voltage battery and vehicle controller failure. Tesla technician replaced those electrical components with service fee charged.

Both rear seat belt buckles (driver-side rear and center) fail to latch securely. The metal tongue inserts fully into the buckle but does not lock with an audible click and releases immediately upon light tension. This prevents the seat belts from restraining passengers in a crash. - No visible debris, damage, or contamination in either buckle. - Issue occurs consistently on multiple attempts and with different seat belt tongues. - Vehicle is 2021 Model Y Long Range with 83,610 miles. - **Problem first noticed yesterday (November 2, 2025)**. - Tesla Service has refused repair under warranty, stating the vehicle is out of warranty, despite this being a critical safety component governed by FMVSS 209. This is a **safety defect**, not normal wear. The rear seat belts are **inoperable**, rendering the rear seating positions **unsafe and non-compliant with federal safety standards**. Similar failures are widely reported by other Model Y owners on NHTSA and Tesla forums. REQUEST: Please investigate this recurring seat belt buckle latching failure in Tesla Model Y vehicles. A recall or safety improvement campaign may be warranted.

On October 2, my Model Y battery was replaced with a defective cell. Tesla service center replaced the battery. The vehicle could not charge or operate, making it unable to be driven. Today, November 2, while driving my car, my Tesla ABS system and other battery components experienced total failure while driving. For a brief period of time, I was unable to brake completely and my vehicle felt like it was skidding. At the time this occurred, my 1 year old daughter and pregnant wife were in the vehicle. This could have been much worse.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at an undisclosed speed, there was a loud clunking sound coming from the rear driver’s side of the vehicle. There was no warning light illuminated. After the failure had occurred, the mechanic who towed the vehicle informed the contact that the failure could be related to a detached axle. The vehicle was towed to the dealer, where it was diagnosed and determined that the front suspension lateral link had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. After researching, the contact discovered NHTSA Campaign Number: 21V835000 (Suspension). The contact expressed concerns that the vehicle should be included in the recall due to the similarities between the reported failure and the recall summary. The approximate failure mileage was 45,483.

The driver rear left side door is unclear electrical control and broke so I cannot open the door from the outside. I have a child inside. This is an extreme safety hazard were an accident to occur.

The contact owns a 2021 Tesla Model Y. The contact stated that while coasting into the garage, the vehicle independently accelerated. No warning light was illuminated. An independent mechanic or dealer was not contacted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. However, the contact was in the process of repairing the vehicle. The manufacturer was not notified of the failure. The approximate failure mileage was 38,727.

I am reporting a safety issue involving my 2021 Tesla Model Y. The vehicle recently displayed a “Parking brake function degraded” warning. The car has only 91,000 miles and is approximately four years old, which is far too soon for a failure of a critical safety component such as the electronic parking brake. Please investigate whether this issue is part of a wider defect affecting Tesla Model Y vehicles. This should not occur on a relatively new car with moderate mileage.

Rear cameras and side cameras suddenly failed resulting in low visibility and severe blind spots increasing the chances of collision with other vehicles, people, etc. It is reproducible at the dealer and they are trying to fix the problem by replacing the computer. It can be inspected until dealer repairs the issue. The vehicle has only been inspected by the dealer. There was a warning on the screen starting that cameras are temporarily unavailable but camera function did not return after a week and brought to the dealer for repair.

I was driving along one of the main highways in Orlando, Florida called [XXX], on Wednesday [XXX], in my Model Y Tesla. I was between the exits of [XXX], and [XXX]. I was in the middle lane. There was a software update issued the previous Sunday. The warning came on the display that the lane changing was not valid. At that point the car took over and accelerated. The brakes would not work, until I slammed on it after 3 times, and the car began to decelerate. The air conditioner went off, along with the electrical turn signals. I as able to get off at the [XXX] exit for it is a bit of a "hill" up in Florida, but knew I could coast into a lane hopefully no one would be in. I was able to at least coast into a parking lot, and bump the car into a concrete barrier, and a tree infront of the barrier. The car would not respond to park, neutral or the emergency brake. I tried re-booting the car 3 times and nothing. I had to call a tow truck to tow to the Tesla Service Center in Clermont, Florida. They could not get it in park either and had to drag the Tesla onto the flatbed. After 5 days of not responding to my text, I walked into another Tesla service center to plead my problem. Long story short, there is an unexplained anomaly that is in the CANBUS and cannot duplicate the error. More $ to have to tested for another week. They gave me a loaner to use, a Model S. After a few days driving it the loaner screen went blank and I was stranded. I had their loaner towed back to the servic

🚨 Immediate Escalation: Safety-Related HV Drive-System Concern / Diagnostic Fee Dispute / No Loaner – Urgent Review Needed VIN [XXX] I am requesting immediate escalation of a safety-related concern involving my 2021 Model Y (approx. 90,000 miles) currently assigned to the Tesla Wilmington Service Center. The advisors (Shelly & Amanda) has stated the diagnostic fee will not be covered until after inspection, but the earliest inspection is October 22, and I’m being asked to drop off the vehicle now with no loaner or transportation support. This is a High-Voltage Drive-System concern that may fall under the Drive Unit Limited Warranty (valid through Feb 2029). The local team refuses to classify the case under warranty review or confirm transportation support, leaving me without safe mobility for weeks. Please escalate this to a Corporate Service Manager or HV Warranty Specialist today and confirm: 1. That the diagnostic will be covered pending warranty review, and 2. That loaner or transportation support will be provided. I’ve been going back and forth with the Wilmington team for a week, and this matter has not been resolved. Despite this being a SAFETY concern and issue . I was told that that O would have to wait weeks to get this issue resolved.

The rear passenger door was stuck in the closed position and would not open. We brought this to Tesla to fix 5 separate times. My kids sit in the back seat and were not able to get out of the car. We were very worried about their safety because if there was an accident or emergency and they had to get out, they would be stuck inside the car. Each time we brought it to Tesla for repair they "fixed it," only to have the problem occur again weeks to months later. This is a HUGE safety issue. We will attach invoices to this but the dates this occured were 10.3.22, 5.2.23, 6.5.23, 6.21.23, and 4.25.25,

On August 20th, 2025 at 2:50pm, my eight-month-old infant was trapped inside my Tesla Model Y for approximately 30 minutes due to a critical systems failure. The vehicle experienced an error with the 12V battery that rendered the doors, windows, and trunk completely inoperable, preventing any means of access or escape. My infant was flushed, diaphoretic, and crying while stuck in his car seat with an indoor temperature exceeding 104 degrees fahrenheit. Despite all attempts to override the system, the car remained locked, and the battery dead, and emergency services had to be contacted. Officers from the Santa Barbara Sheriff’s Department, California Highway Patrol, and Montecito Fire Department arrived on scene and, in order to rescue my baby, were forced to smash a window to gain entry. The police officer was advised by a Tesla representative to do so, as he confirmed there would be no way to override the system to open the doors. My baby was found screaming in a pool full of sweat and was carried to an ambulance, where the paramedic warned me of concerning vital signs and advised me to go to the Santa Barbara Cottage Hospital to have his condition assessed and treated, if necessary. I have obtained a copy of the police report (Case No. XXX) and will provide it upon request. Tesla confirmed that this problem with the 12V battery is common, nonetheless we were made to pay for a new window and a battery replacement. There were no warning signs leading up to the shutdown and no

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the front end of the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who determined that the front suspension lateral link fasteners were loosened. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V835000 (Suspension), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 22,000.

Front suspension upper control arm makes loud creaking/squeaking noises when turning at low speeds. This is a known and widespread issue affecting Tesla Model Y and Model 3 vehicles, caused by premature ball joint wear. This poses a safety risk, as the upper control arm is a critical suspension component and could fail while driving, potentially leading to loss of steering control. Tesla has acknowledged the issue through service bulletins, but they do not cover the repair outside the 4yr/50k mile warranty, leaving many owners with the same premature failure. Some repairs may be offered under goodwill, but this is inconsistent and not guaranteed.

On July 5, 2025, I entered my vehicle parked in my home garage and the door latched shut. Upon putting my foot on the brake. Center screen was blank (did not power on). I attempted to press the unlock button on the door and there was no sound from the motor to open the door. The door was still locked from the inside of the vehicle and I was locked inside. I waited around 5 minutes (after attempting to call my wife to try to let me out of car and tried the open the drivers door again by pressing the exit button. The door unlatched by normally the window rolls down partially to exit. This time the window did not move and I have to force the door open by pressing my shoulder hard against the interior door panel. I hear a popping sound from inside the door and the window would not roll up. I did not drive the vehicle fearing that the car would not start and my family could be trapped inside the car. I created an appointment for Tesla service for July 7, 2025 for the door locks and the driver's window that would not roll up completely and also would roll down but return to a 70% rolled up position automatically. I did received an error warning on the late evening of July 6, 2025 that the 12 volt battery voltage was low on the main center screen of my vehicle. I took the vehicle to Tesla service on July 7, 2025 and it was determined that the 12 volt auxiliary battery that was faulty and my window was repaired and recalibrated. I never saw an alert for the 12 volt auxiliary battery

[XXX] , my [XXX] son, was strapped in his car seat, wide-eyed and confused, as we sat trapped in our Tesla for thirty agonizing minutes. The battery had died without warning, leaving us locked inside our own garage. No power, no way to open the doors. I tried to keep [XXX] calm, singing his favorite songs, but my heart raced as I called for help. A tow truck finally arrived and jumped the car—not enough juice to start the engine, but just enough to unlock the doors. Freedom at last. Tesla’s response? No roadside service; they insisted the car be towed to their service center. Easier said than done—the tow truck couldn’t maneuver it out of the garage. Frustration mounted as I realized I’d have to miss work. Days later, I drove to the service center, where they replaced the battery. But the ordeal wasn’t over. The trim was damaged during the chaos, and now every drive is accompanied by relentless wind noise, a constant reminder of that day. [XXX] still talks about being “stuck in the car,” and I can’t help but feel let down by a system that left us stranded.
