2019 TESLA MODEL 3 Complaints

Driving as normal when an alert for a front passenger safety restraint system fault appeared. It went away on its own. I thought it was a software glitch. It would periodically reappear, then go away after a driving session. Last week it persisted between sessions. I learned that if the seat was moved slightly forward or back, then the alert would go away. I scheduled a service with Tesla. Tesla advised that the entire car seat and airbag would have to be replaced for $1800. This is a ~50,000 mile car with no collision history. It's just out of warranty. Tesla refuses to tell me if the car will safety function in an accident or not. The alert is gone, but I have a service estimate that says the car has all of these problems. Major safety concern.

There is an error with my car's Occupant Classification System (OCS) which is giving me an alarm of "Front Passenger Safety Restraint System Fault". Tesla only "fix" is to replace the OCS with what seems to be a newer version. You can tell it is a new version because they are also telling me I need to replace my airbag as my current airbag is not compatible with the new OCS.

Front suspension has lost lower lateral link and bolt. There was a recall on this back in 2023 for our year and model but our car was no selected. Clearly it should have been as the suspension has failed. Please see invoice from Tesla attached. This should be taken care of by Tesla as it is a known issue.

I am reaching out to report a high voltage isolation issue with my 2019 Tesla Model 3. Tesla determined the issue was caused by external factors such as grime and road salt corroding the battery seals, leading to an internal isolation fault with the high voltage battery. They deemed it out of warranty, with an estimated repair cost of $13,155.30. When I asked what preventative maintenance could have avoided this, Tesla only referred me to the owner’s manual, which simply instructs users to clean the car’s exterior. No specific maintenance regarding battery seal inspection or corrosion prevention was provided. Records from our local car wash subscription show the car has been washed regularly (at least 66 times since January 2024). The previous owner also had brake lines replaced due to corrosion under warranty, during which Tesla removed the battery in March 2023. In October 2024, the rear drive unit was replaced under warranty, yet no mention was made of battery seal corrosion during any of these service visits. At no point has Tesla’s maintenance guidance or service process addressed checking the seals for corrosion in regions where road salt is heavily used. I believe this omission creates a potential safety concern, as seal corrosion in a high voltage battery could lead to failures or hazards without prior warning. The Vermont AG Consumer Assistance Program recommended I contact your office for further assistance. This issue appears to be part of a broader pattern where Tesla attributes failures to “environmental factors” without advising owners of any specific preventative maintenance, effectively avoiding warranty responsibility while leaving potential safety issues unaddressed.

My vehicle displays a persistent warning: “Front Left Safety Restraint System Fault.” A technician told me this fault relates to the driver seat sensor and is the same defect addressed by a previous NHTSA recall. However, I’ve confirmed that my VIN was not included in that recall. Despite the recall fix being implemented for some vehicles, my car still has this safety restraint fault with no resolution offered. This ongoing problem concerns me because it affects the proper functioning of the vehicle’s safety system, and I fear that my vehicle’s defect remains unaddressed. I request that NHTSA investigate this issue, as it appears the recall did not cover all affected vehicles and that Tesla’s recall scope may be insufficient.

The contact owns a 2019 Tesla Model 3. The contact stated that the passenger's side air bag warning light was illuminated. The vehicle was taken to the Tesla Service Center, where it was diagnosed and determined that the passenger's side seat sensor had failed. The seat was replaced with a new seat; however, the air bag warning illuminated after the repair. The vehicle was taken back to the service center, where the contact was informed that the technician had failed to install the module connected to the air bag during the previous repair. The seat replacement was performed a second time; however, the failure persisted, and the contact noticed that the seat was not installed correctly. The contact requested for another service through the Tesla App, but the request was denied. The contact was informed that the vehicle was repaired, and the notification of the failure was due to a glitch in the system. Additionally, while driving at various speeds, there was an abnormal creaking sound coming from the front suspension. The contact stated that the sound became louder while turning. An appointment was scheduled with the Tesla Service Center. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

Passenger Restraint System Fault causing the system not to sense the presence of front passengers. This could possibly lead to safety systems for the passenger to not work in the event of a crash.

The vehicle’s front suspension began making loud squeaking noises and felt unstable while driving, especially when turning or going over uneven surfaces. At times, the vehicle does not make a proper turn and almost feels like it loses grip, which is extremely unsafe. I brought the vehicle to a Tesla service center. After inspection, Tesla provided a service estimate and documentation confirming the failure of the front lower lateral links — the exact part and condition described in NHTSA Safety Recalls 21V835000 and 23V235000, which cover defective front suspension lateral link fasteners on this vehicle make, model, and year. Despite the clear match, Tesla did not recognize the repair as recall-related and categorized it as a customer-pay service. This raises concern that some affected vehicles are being excluded from proper recall coverage, despite experiencing the same safety defects. There were no warning lights or alerts prior to the failure. The issue was confirmed by Tesla and the part is available for inspection upon request.

My vehicle was working fine when Tesla issued an over-the-air software update recently. The next day, my backup camera was not working. The back up camera is required for this vehicle under FMVSS 111 and is otherwise essential for this vehicle due to limited rear vision through the rear window. In addition, GPS/navigation stopped working, the windshield wipers did not function on certain settings and the display was at times not legible, presumably because it believed it was a different time of day and was in the wrong mode. There are likely additional issues that have not revealed themselves yet. I took the vehicle to the local Tesla Service Center on July 25, 2025. They confirmed the reported issues and said it was a problem with the software update, which they would perform onsite while I waited. The service center personnel also stated this was not a firmware issue or anything to do with my car and that it was just the software update. After a few hours, the personnel reported they could not get the update to install and asked that I bring the vehicle back the following week for further diagnostics. Before I brought the vehicle back, I was sent an invoice for approximately $2,300 for replacement of on vehicle's computer. I brought the vehicle back today, July 29, 2025, and asked them to perform the onsite diagnostics they wanted me to bring the vehicle back in for and did not agree to pay for the computer replacement. I also informed the Tesla personnel that, at a minimum, the the back up camera failure is a safety related issued covered for this vehicle under FMVSS 111 and that they were not permitted to charge me for fixing it. The vehicle warranty period recently expired but it is well within the 10-year date of manufacture. Other issues with the vehicle may also qualify as safety related, but the back up camera is clearly one - Tesla recently issued a recall for this very same problem impacting the Model 3, but the recall did not include my model year.

The rear camera on my Tesla intermittently fails when shifting into reverse. Additionally, the rear trunk will not open using the in-car release button, mobile app, or key fob. A warning appears stating the function will return on the next drive, but I am often forced to use the emergency release to access the trunk. I believe this may be related to a prior recall involving the rear trunk harness, but when checking my VIN, no active recalls appear. Tesla service also reports no recalls on file. I am also receiving an intermittent fault message regarding the front passenger safety restraint system, stating that service is required. This is a serious concern, as a malfunctioning restraint system may fail to protect occupants in the event of a crash. Tesla has given me an estimate of $225.00 to address the safety restraint fault and $495.27 to repair the trunk/rear camera issues, with a total cost of $739.60 including taxes. I believe that safety-related repairs, especially those involving airbag and restraint systems, should be covered by the manufacturer and not passed on to the vehicle owner when not due to misuse or damage. The passenger restraint fault poses a direct safety hazard in a crash. The rear camera issue, while less severe, still impacts safety, as the camera provides a wider and clearer view than mirrors alone. I am asking NHTSA to review whether these issues are safety defects and whether they may be connected to known problems or recalls not applied to my vehicle.
