2018 Tesla Model 3 complaints

My 2018 Model 3 recently started experiencing issues during AC charging where I’m only able to use 16A out of the 48A available from my Tesla mobile connector charger at home. The specific error warning and error I’m seeing says “PCS_a019 Power grid or vehicle issue limiting AC charging Unplug and retry/ Try different charging location”. Before this started happening I’ve been charging with the same charging setup at home since 2019 and have been getting 32A consistently. I’ve tried the following options to diagnose the issue: 1. I’ve unplug and replug mobile charger from the connector. (the end plug to the mobile charger), I’ve also plug and unplug connector to the nema 14-50 receptacle. 1. The mobile connector exterior shows a constant flowing of green color on the “TESLA” letters outside the charger 2. I also separately own a second 2023 Model Y Performance, my Model Y is able to use the same Tesla mobile charger connector/receptacle at my home. It it getting AC charging at 32A 3. I’ve also tried charging the 2018 Model 3 (w/ the issue) at another separate AC charging station from a friend’s house that can normally deliver 48A, but I’m still also only getting 16A out of the possible 48A After sending the above to Tesla service center, they remotely diagnose and stated that it was an partial failure/issue with the " Power Conversion System" on the vehicle. However, Tesla mentions that is is not covered by their "HV Battery Warranty" and only covered by their 4 year 50k mile

Got an alert on the Tesla screen on 4/21/2025 indicating "Front left safety restraint system fault". Took to Tesla Svc Center and they replaced seat belt lap pretensioner, seat belt reminder vent, seat belt reminder sensor box and first row occupancy sensor. Cost $650. Alert goes away if I raise the seat and comes back if I lower the seat. I asked Tesla while scheduling an appointment whether it was a safety issue and they said "Yes". Vehicle has only 43,500 miles on it.

Upon entering my vehicle, which was in my garage, I put it into reverse. I found the steering wheel extremely difficult to turn and upon viewing the screen I saw a message stating "Steering assist reduced. Steering may require increased effort". I backed up about 10 feet and still was unable to turn the steering wheel. I noticed another message advising "Lane Departure Avoidance features unavailable. Features may be restored on next drive". I pulled back into the garage and rebooted the car to no avail. I let the car sit for several hours before trying again. This time the steering was fine. I am scheduled to have the manufacturer inspect the car on Tuesday April 29, 2025.

Power Conversion System (PCS) failed Doesn’t allow car to charge. Car has only 33k Miles on it.

Front suspension is making very weird and loud noises. Issue is associated with the front suspension links becoming loose.

Tesla is aware of a common regarding an occupancy sensor in the passenger seat of their vehicles that impacts functionality of airbags and the restraint system. The error code is RCM_a056. A simple search of the code will show a myriad of ongoing issues with their vehicles

Alert message on car "safety restraint system issue"

1. The Power Conversion System (PCS), still in the vehicle and not available for inspection 2. 2 of the 3 controllers have failed, resulting in limited AC charging (16A out of 48A max). The PCS helps regulate AC and DC electricity and connects the 12V batter to the HV battery. If it fails, it could lead to dangerous situations since the electricity from the HV battery wouldn't be as controlled. I'm worried that if the final controller fails while driving it could lead to a loss of power. 3. Problem throws an error code when charging that the dealer has verified, they will not replace it unless I pay for the part+labor which is roughly $1,800. 4. Vehicle inspected by dealer, they will only fix if I pay for replacement part. 5. Car has warning message when charging.

1. PTC Heater, old part is available for inspection 2. PTC heater failed while driving, experienced loss of power and slow loss of secondary electrical systems (the 12v battery was not able to recharge itself with the PTC heater not functioning). When attempting to restart car after pulling into a parking lot, the entire car died (12V battery was drained so it couldn't start up) and had to get towed to Tesla service center. PTC heater is critical for car to operate as it is closely linked to 12V battery. Additionally, without PTC heater car cannot defog windshield, resulting in potentially poor visibility. 3. Dealer replaced the defective part (PTC heater) and had to replace 12V battery as well. Was not covered under warranty and I had to pay the cost out of pocket. 4. Inspected by manufacturer and replaced. 5. Got warning signs about reduced power available, and secondary electrical features were limited.

The driver side seatbelt/presence sensor intermittently fails due to faulty wiring. This causes a warning stating 'front left safety restraint system fault' and the driver side airbag to turn off when the warning is present causing a severe safety issue. This is a well documented common safety failure of these vehicles

RCM_a021 alert: Front left safety restraint system fault. Seems like an issue caused by seat movement back & forth.

On March 21, 2025, my Tesla Model 3 Long Range entered "Power Reduction Mode" — a safety feature that limits power to protect the high-voltage battery from overheating or failure. Tesla later diagnosed a coolant leak near the battery area. Their own service advisor stated in writing that the failure was “most likely related” to the battery’s thermal management system — the very system responsible for regulating battery temperature and preventing damage. Despite the connection to the battery protection system and the vehicle being under the 8-year/120,000-mile battery warranty, Tesla has refused to cover the repair. The issue remains unresolved, and I have not picked up or approved any repairs on the vehicle. My concern is that driving the vehicle in this state — or leaving this failure unaddressed — could lead to further battery damage or pose a safety risk. I am requesting that NHTSA evaluate this issue as a potential safety concern, especially as the manufacturer is refusing to repair a system directly linked to high-voltage battery safety.

While regularly driving I experienced a gradual squeaking sounds from the front suspension. A few moments later I noticed that my steering wheel was acting as if it didn’t have power steering. I’m lead to believe that due to the poor design of my Model 3, that the outside elements were easily able to make its way to my Universal power steering shaft leading Tesla to remove and replace my steering shaft and my Upper control arms as well. The rust on the U shaft was incredible, I’ve only driven in the snow one time and immediately the noises starting happening. I paid everything out of my own pocket due to the undeliverable conditions my steering wheels was in.

I received and indicator noting that my front passenger safty system has a fault. They indicated that they will have to replace the seat sensor and the airbag. I believe this to be an innate fault of the cars construction. It is dangerous and should be fixed by Tesla and not charged to the customer.

October 12, 2024. I was using the Tesla on autopilot. I was in the far right lane and the freeway was curving to the left. The car was following in the lanes, but then all of a sudden it stopped following the freeway and drove into the right guardrail. There were no alerts by the car. It did not warn to take over the vehicle or attempt to avoid the collision. The car drove directly into the guardrail without warning and was totalled.

This is a widespread safety issue that requires a recall! This is not isolated. Model 3 passenger airbags are at risk of not deploying.

Right front upper control arm began making noise and was replaced under warranty at 42k miles in Sept 2019. Left front upper control arm failed around 50k miles and caused a wreck resulting in $8,365 in damages in April 2021. When fixing one side it is standard to replace the other and Tesla was negligent. Upon fixing the left side suspension at Blue Ash Auto Body in 2021, the brake caliper came loose while driving on the highway while on a vacation. This caused an additional $1500 or so in charges. Both of these incidents put my life and my son's life in danger. About a week or two after the caliper problem, Tesla issued a recall for that part stating that it is now single use only.

Vehicle Information: Make: Tesla Model: Model 3 Mid Range Year: 2018 VIN: [XXX] Mileage: 60,000 Issue Description: My 2018 Tesla Model 3 is experiencing premature wear of the front upper control arm ball joints and lower links at only 60,000 miles, despite the sealant fix from Tesla Service Bulletin SB-20-31-006 being previously applied. This premature wear suggests a defect in materials or design and poses a potential safety risk due to compromised handling. Request: I would like some information on the current situation, if tesla has already told their stance on the issue, if I qualify for any coverage even out of warranty. Anything that can help others when their suspension front goes out extremely prematurely.

The car started making a strange high pitched creak sound whenever I would turn the steering wheel, or go over bumps in the road. I brought the car to Tesla and they informed me that the following parts needed to be replaced. 1. Front Lower Compliance links (left and right) 2. Front Lower Lateral Link (left and right) I was notified that the failure of those components was a potentially serious safety issue, and that the parts needed to be replaced as soon as possible. I had Tesla replace the parts, so the issue cannot be inspected. The problem was verified by the Tesla Service Center, and was not seen by any other professionals. There were no real warnings, other than the annoying squeak sound whenever the sterring wheel was turned. The sound first appeared in November of 2024.

The front suspension lateral link on our Model 3 came detached from the subframe as the bolts someone loosened. This is a known issue and Tesla has issued a recall (NHTSA Recall No: 23V-235) on this year Model 3, but our VIN is not included in the recall. It seems that this issue is wider than the cars the original recall has included. Upon detachment, the wheel steering did not work, and if it highway speeds, could have cause a fatal accident.

Warning message appeared on center screen stating: "Front left safety restraint system fault". This appears to be a safety related problem , Tesla dealer wants $500 to repair because the vehicle is "out of warreanty" . This is the second Model 3 we have had. Previous version also experienced this fault. Is this a safety problem and if so should the car manufacturer be responsible to repair at no cost to owner? I have receoved a notice from NHTSA dated 5-31-2024 stating recall 24V376 may affect my vehicle - Seat Belt warning Sustem. I have not receoved a specific recall from tesla for this recall. Is it the same as the fault referenced above?

The suspension on this car developed a persistent noise that worsened over time, prompting me to schedule a service appointment at the Tesla dealership. Although my car has less than 40,000 miles and has been driven primarily on well-paved city roads, both front suspensions were found to require extensive repairs, a final bill of approximately $2,100. Safety Concerns: Frequent Suspension Issues in Teslas: Online research and data from the NHTSA indicate a disproportionately high number of suspension and steering complaints for Tesla vehicles. In 2023, Tesla owners filed over 260 complaints, significantly higher proportionally than Toyota, despite Tesla's much smaller sales volume. Such trends suggest potential systemic quality issues in Tesla’s manufacturing process. Simultaneous Suspension Failure: The need to replace multiple components in both front suspensions at just 30,000+ miles raises serious questions about the reliability and safety. A single suspension failure could be a bad luck, but simultaneous failures point to broader design or manufacturing problems. Risk of Accidents: Suspension failure compromises vehicle control, increasing the risk of accidents that endanger drivers, passengers, and others on the road. Transparency Issues in the Repair Process: The initial repair estimate of $200 excluded labor costs and was revised to $400 without prior clarity. After inspection, the cost escalated to $2,100, leaving me no option but to approve the repairs without the ab

Tesla 3 was self parking backwards and failed to stop when the car in the adjacent parking spot started moving. The result was a small scratch, but this is definitely a bug in Tesla self-parking software: it had to stop when another car moves into the stop Tesal selected for self-parking.

I received an onboard alert that says ‘Safety Restraint System Issue/Service is required.’ According to online Tesla Forums, this is a very common issue with the Model 3 drivers side air bag system. Although some relate it to a wire under the seat that becomes worn with movement of the seat, Tesla gives an estimate of over $1,000 to fix the problem. There repair estimate involves updating the front passenger airbag ($444), and replacing the occupant classification system ($426).

The contact owns a 2018 Tesla Model 3. The contact stated that on several occasions while making left or right turns, there was a loud clanking noise emanating from the front of the vehicle. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the lower control arm bushings had deteriorated and needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer several months later where it was diagnosed that the bushings and one of the well nuts had sheared off, and the subframe needed to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 40,000.

Control arm of the left front suspension system detached with no warning other than an occasional noise that started about 2 weeks before the incident, usually when turning the front wheels at slow speed. This was a potentially dangerous situation for the driver, passengers, and any other vehicles on the road as the tire could have come off at any time. Fortunately the car was being parked (0-1 mph) in a non-congested area when the control arm detached. The vehicle (total mileage approximately 42k) was towed to a Tesla Service Center 2 days later where the problem--first diagnosed by the tow truck driver--was confirmed by a Tesla service representative. There was no warning of any problem other than the occasional noise mentioned previously. If this parts failure had occurred at high speed on an interstate highway, it would likely have been deadly!

I was at a stoplight behind a Toyota Tacoma. I must have stopped around 8 feet behind it. I was not using FSD and I was not one-pedal driving. My foot was on the brake. I must have been at a complete stop for approximately 10 seconds when my Model 3 suddenly accelerated full throttle on its own and rear ended the Tacoma, directly hitting its trailer hitch, causing my car's driver-side airbags to deploy. When it happened, the light was still red and my foot was still on the brake. I never touched the accelerator. Luckily I was driving alone. After the inital contact, my car sort of bounced off of his hitch then slowly lurched forward before it stopped. After that, it was immobile, leaving me stuck in traffic until it was towed away.

Control arm issue and linkage cable.

On December 24, 2024 I was driving on Freeway 5 South and all of the sudden my vehicle came to an abrupt breaking without any reason. The traffic ahead of me was of normal traffic. This abrupt breaking happened twice within 5 minutes of time span. I have notified Tesla Service Center and the service center gave me a quote of $137.50 for diagnostic and to schedule the service. I felt that this issues should be taken care of by Tesla with no charge to me. This is a safety issue. I have experienced the abrupt breaking issues with my vehicle on many occasions since I own the vehicle in 2018. Each time I was told there's no problem with the vehicle when I notified Tesla Service Center.

Under-torqued Lateral link bolt These bolts are known to fall out or cause damage to bushings from being installed improperly Failure of the suspension would result in the suspension collapsing and the car becoming uncontrollable, with serious risks at higher speeds Out of pocket repair has been made by Tesla Component has been inspected and tightened to spec No warning sings, other than loud, clunking noises At 40k miles on smooth roads, this is not a driver issue, but a manufacturer assembly issue. They already have a recall for other VINs in other years, but I believe this should be expanded to more VINs and years, as this appears to be a common issue.

Front suspension lateral link fasteners loosened, allowing the lateral link to separate from the sub-frame. I have a 2018 Model 3 and this seems to be the exact same issue that led to a recent recall with the help of the NHTSA. Recall no. 23V235000 SB-23-31-001 An expansion of previous recall number 21V-835. I noticed for months something was slightly off in the front right area of the car. I brought it into the Tesla service center, they drove it and didn't notice anything. About a month later the lateral link separated from the subframe rendering the car undriveable. I had it towed immediately.

Passenger Safety Restraint system fault. Faulty wiring under the seat. Cost of repair is $1000. Passenger airbag requires replacement.

I’m not exactly sure what’s wrong, the screen keeps failing on my car. It’s been taken to Tesla to service this issue 4 times. With the most expensive repair costing $2,200. Its poses a safety hazard because when the screen fails. You can’t see anything, speed, gear. You can’t adjust windshield wipers, seat or mirror positions.

Power conversion system (PSC) failure. Only charges at 16 amps. I know other Tesla owners have had this problem as well.

I took my car in to Tesla to have the tires replaced, during the service appointment my frunk was opened and closed by the technicians. Within ten miles of leaving the dealership my hood/frunk flew open and broke my windshield and frunk hood

Received safety restaurant system warning on my Tesla. This is a safety issue with the seat belts. This was repaired already on November 4, 2021. Same issue occurring again and but Tesla now wants to charge $400 to repair.

In several accidents and fires in model 3s it became apparent that when the electric door openers on the rear door fail the backup mechanical system is completely inadequate particularly for incidental passengers. Unlike the front seats which have a level to pull up to open the door the rear doors require a number of steps that are odd and certainly not obvious or intuitive leading to a very dangerous situation when a very fast exit is needed. The rear should have the same type of level to provide consistency for riders in an emergency situation. As someone who owns Tesla and uses many UBER Tesla's in the back seat I have quired drivers who generally have no idea that the rear seat passengers could easily trapped in the car in an emergency and do not know how to open the doors from the inside.

The error popped up randomly and states "front left safety restraint system fault." This has been a common problem with Tesla and should be a recall as it's a manufacture defect with a safety system.

Safety restraint system issue if this is an on-going issue with many Tesla users, shouldn't this covered under a warranty being it is a safety issue?

1. I had my car for only 6 years, and the main monitor would randomly go black. I have to do multiple hard resets to get it to work again. 2. I'm getting a Front left safety restrain system fault, on a car that I had only for 6 years. Compared to my Prius that I had more than 10 years, which I had no problems AT ALL, Tesla is junk. 3. Front suspension is squeaking when making turns at slow speeds. Review of YouTube indicates that this is a very common problem. Tesla should fix this for free instead of charging $800.

Two incidents while testing the most recent version of Tesla's "Full Self-Driving": 1. While driving at less than 25mph in a residential neighborhood, using the "Full Self-Driving" mode, the car was entirely unable to detect either heavy steel plates in the road (being used to cover road work) or significant potholes in the area near the plates. 2. While driving on H1 (a federal "interstate" highway) on Oahu, at approximately 55mph, using the Tesla's "Full Self-Driving", the car inexplicably slammed on the brakes. There was absolutely nothing visibly in front of the car for at least 200 yards. The car behind me had to swerve to avoid rear-ending my vehicle.

AC Power Control System Failure - I didn't know about this problem until two weeks ago I went to Tesla service center. I was facing this problem since 2020, when car was under 4 years warranty but never complain thought home power source charge that much only.

"Front Passenger Safety Restraint System Fault​" a safety concern that puts passenger in danger with a faulty restraint system. Problem constantly reproduced every time get into car. It is available for inspection upon request. Car has not been physically inspected, but has been remotely accessed by manufacture and is charging owners $436.06 to repair. There has been no warning messages nor other symptoms prior to failure. Problem 1st appeared about a month ago.

ISSUE: PTC Heater failed at 63,617 miles after 6 years of use WARNING MESSAGE: "Vehicle may not restart" CONTACT: [XXX] [XXX] main contact for owner [XXX] . VIN: [XXX] MAKE: MODEL 3 YEAR: 2018 REPAIR QUOTED: $1,104.18 LINE ITEMS: PTC HEATER DUALZONE(1088218-00-I) HVAC, PTC SERVICEASSY(1107677-00-A) LABOR & DIAGNOSTICS SUMMARY: TESLA Model 3 Electric Vehicle shut down into "Asleep mode" and will not respond (turn back on). Locked out. Will not wake up. Will not respond to software nor car keys. All systems turned off. Will not charge. Will not release charger from charge port. Issue suddenly happened after [XXX] software load (deemed to not be the cause of issue). Dealership diagnostic shows PTC Heater failure which cuts off the battery. Dealership quoted estimated repair (see below). This could have happened while driving causing the vehicle to be uncontrollable, and a major safety issue. Fortunately, my incident happened after I parked the car in the garage. Overnight there was a software install (supposedly not causing the problem). In the morning the vehicle would not turn on. PRECEDENT: There were several small claims filings in Canada for same issue. This was deemed a design flaw, and safety issue. (See [XXX] ) DIAGNOSTICS: On-line debugging is pointing to resistance issue with 1 of the 5 heating elements in the PTC Heater. PTC Heater cuts off supply to PCS which charges the 12V battery when there is an issue with the heater. This allows the 12v battery to drain, and the
