2019 Tesla Model 3 Complaints

I am submitting a complaint regarding a “Front Passenger Safety Restraint System Fault” warning that recently appeared on my Tesla vehicle. My vehicle currently has approximately 45,000 miles. This warning indicates a potential issue with the passenger airbag or related restraint system components, which is a critical safety feature. A malfunction in this system raises serious concerns about whether the passenger airbag would deploy properly in the event of a crash. I contacted Tesla service, and I was informed that the repair would cost over $1,500 out of pocket. Given the relatively low mileage and the importance of the safety system involved, I am concerned that this may represent a broader defect rather than normal wear and tear. Additionally, I have found similar reports online from other Tesla owners experiencing the same warning, which suggests this may not be an isolated incident. A failure or malfunction of the passenger restraint system presents a significant safety risk...

The car was giving me a warning "Front Left Restraint System Fault" (RCM_a021) approximately for 4 months (Jan 2026?) - I brought the car in for service April 2026 and after researching, the technician found that there was a failure in the wiring harness - this is the wiring harness that is responsible for the seatbelt pretension mechanism that activates in a accident. The technician had to replace the harness for the issue to resolve. However, it's my understanding that, had an accident occurred prior to the repair, that the safety system would not have operated properly.

The Tesla was hit on the passenger side by a Honda civic that ran a red light traveling more than 25 mph The Tesla spun 180 degrees after impact. No airbags deployed. Immediately after impact the Tesla turned on hazard lights. However the vehicle would not come to a stop after pressing on the brakes. After impact the vehicle was coasting backwards at probably less than 5-6 mph. It would not respond to brake presses. Oddly the vehicle had regen braking enabled which should have brought it to a stop, but it didn’t. The vehicle kept coasting backwards as if it was in neutral for about 20 meters until it hit a curb and stopped. BRAKES WOULD NOT WORK!!!

I received a notice onscreen (photo attached) that says "Front passenger safety restraint system issue, Service is required." I did some research online and a number of other owners of 2019 Tesla Model 3 vehicles have received this warning, which involves a malfunction that is a combination of the front passenger seat belt, air bag, and seat sensor for the air bag. A number of people with this year and make have gone to Tesla, and Tesla service workers have said "this a known issue" for this year and make. Since this issue involves a number of safety components, and is a known issue, Tesla should be required to fix this as a product defect recall. Instead, they quoted multiple owners, including myself, approximately $2,000 to fix.

The contact owns a 2019 Tesla Model 3. The contact stated that while the vehicle was stopped at a residential gate, the vehicle unexpectedly accelerated. There was no warning light illuminated. The vehicle was towed to a private residence. No warning light was illuminated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 80,000.
