2019 Tesla Model 3 Complaints

Alert RCM_a021pretenLapFrontLeft. Caused by the seat harness wires being pinched and stretched when moving the seat back/forward/up/down. Eventually the wires are damaged by the seat movement. Tesla has touted a feature called "Easy Entry" which moves the seat to a preset position to allow the driver to get in and out of the car more easily. This moves the seat lower and farther back and then moves the seat back up to the driver's position when ready to drive. This increased seat movement, every time the driver gets in and out of the car, causes the wires to wear prematurely and the above fault to trigger. In the event of an accident the driver side airbag may not deploy and/or the seat belt pretensioner may fail to lock the seat belt in place, leaving the driver exposed to serious potential injury risk. This issue can be seen in 2019 Tesla Model 3s and I believe an investigation by the NHTSA is warranted, at the very least.

Front passenger safety restraint system issue requiring replacement of Occupant Classification System and updating front passenger airbag to maintain compatibility with front passenger seat. Costing almost $2000. Many others have reported of multiple repairs

To Whom It May Concern, I am logging a safety defect complaint regarding my 2019 Tesla Model 3, which displays active fault code RCM_a056 – Front passenger safety restraint system fault. This error deactivates the front passenger airbag and seatbelt pretensioners, creating an immediate, severe safety hazard. The Defect: The failure involves the Occupant Classification System (OCS) seat sensor and affects passengers in two ways: 1. Children (Current Stage): The fault triggers primarily when a child sits in the front seat. The degraded sensor mat cannot process lighter weight accurately, throwing an "implausible voltage" error that disables the airbag system. 2. Adults (Advanced Stage): online data shows this same code eventually locks out for adults due to internal wiring harness fraying or sensor circuit failure. Manufacturer Response: Tesla is aware of this fleet-wide defect and issued Service Bulletin SB-23-20-002 to address it. However, because my vehicle is out of warranty, Tesla r...

Tesla recently introduced auto parking as part of its FSD technology (Software 2026.20.6.11). Whenever we set the car destination to “home”, the auto parking has been able to gradually maneuver the car and self park in our garage. On 8/11, around 8:30pm, the car made a mistake during the auto parking. During the auto reverse into garage, the car came too close to the side of the garage and the driver side mirror hit the wall and partially broke. The driver was monitoring the car. If the car has kept its angle, it would have made it through correctly. But looks like it miscalculated and in a fraction of a second, the car’s side mirror hit the garage wall. Given the “ park” feature is new, looks like it hasn’t been tested well. It should be recalled until it is fixed and impacted drivers should be compensated for their repairs.

I am writing to report a serious safety incident involving my 2019 Tesla Model 3. My goal is not to assign blame, but to make Tesla aware of an incident that I believe warrants review from a safety perspective. While the vehicle was parked, my children were sitting inside watching TV, we were standing 5 ft from the vehicle. My younger son was seated in the front passenger seat, and my older son, not realizing his brother had leaned over the top of the seat, adjusted the passenger seat upward. As the seat moved up, it trapped my younger son's neck against the seat and obstructed his airway. Fortunately, we were a couple of feet away and heard the sound of glass breaking. We were able to free him, and he began breathing again and no serious injury occurs. It was an extremely frightening situation that could have had a much more serious outcome. During the incident, the panoramic glass roof also shattered from the pressure of my youngest son's head. I understand this may have occurred b...
