Tesla Model 3 seat belt problems

Filed Aug 25, 2026 · Airbags, Seat belts · NC

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 federal safety agency is warranted, at the very least.

Between 2023 and 2026, I have had several clunking and creaking sounds from the suspension. These were then found isolated to "lateral and compliance link detachments" and Tesla noted these were "serious safety issues" and fixed them out of warranty at a cost of roughly $2500. When I pointed out that vehicles within this model range (manufactured April 2019 at the Fremont, CA plant) were flagged for a recall, they mentioned my vehicle was outside that range and insisted on an out-of-pocket repair. Further, I have similarly had to have the front left driver's side seat belt harness replaced because of a restraint control module failure. I have owned 3 other vehicles and have never had a restraint control module/seatbelt fail over just 82000 miles of use.

Front Seatbelt On March 13, 2026, at approximately 7:51 PM EST (23:51 UTC), the driver of a 2021 Tesla Model 3 was killed in a head-on collision on SR 741 in Warren County, Ohio. Two people died in this crash — the Tesla driver and the driver of the oncoming vehicle. Tesla's own telematics data (provided to the family post-crash) reveals that the driver's seatbelt unlatched at Row 5115 / 23:51:03.269 UTC — exactly 14.15 seconds before the collision. The driver was actively driving at the time, as confirmed by 66 separate steering torque readings between the seatbelt unlatch and the crash, ranging from −1.59 Nm to +2.15 Nm in constantly alternating directions — the signature of active lane-holding. The seatbelt released on its own while the driver was actively steering based on tesla data at approximately 66 mph. No rational driver unbuckles their seatbelt while driving 66 mph on a busy two-lane road. The telematics data proves continuous active driving before, during, and after the seatbelt event. The seatbelt failure is a separate and independent defect from the Emergency Lane Keeping (ELK) system failure that caused the collision (which is the subject of a separate the federal safety agency complaint). Even if the collision was unavoidable, a functioning seatbelt may have saved the driver's life. The seatbelt failure independently contributed to the fatality. The following data is from Tesla's own telematics file provided to the family: Timestamp (UTC)RowEvent 23:51:03.269 5115 Driver seatbelt status changes from LATCHED to UNLATCHED 23:51:03.269 – 23:51:17.420(row 5115–5311)66 steering torque readings confirm active driving (−1.59 to +2.15 Nm) 23:51:17.4205311ELK system activates (separate defect) ~23:51:19.0—Head-on collision — driver unrestrained — two fatalities Pattern of identical complaints from other 2021 Model 3 owners (ODI 11713076, 11738583, 11684327)

The driver-side seat belt buckle/receptacle failed during normal use. There was no collision, impact, or misuse involved. While using the seat belt as intended, the buckle assembly separated/broke unexpectedly, causing the seat belt to no longer function properly. This appears to be a failure of a critical safety component rather than normal wear and tear. The vehicle should not be considered safe to operate until the restraint system is properly inspected and repaired. The failure occurred without warning and under ordinary driving conditions.

I purchased a new 2025 Tesla Model 3. During normal driving conditions, the rear bumper detached without any collision or impact. The bumper became loose while the vehicle was moving, creating a potential safety hazard. Tesla Service inspected the vehicle but declined warranty coverage and refused to properly repair the issue. The bumper was only temporarily reattached and remains misaligned. Additionally, shortly after purchasing the vehicle, the seat belt assembly had a failure and had to be repaired by Tesla under warranty. While Tesla addressed that issue, it adds to my concern about the overall quality and reliability of a brand-new vehicle. Because the vehicle is new and the failure occurred during normal driving, I believe this may indicate a defect. I am requesting assistance in reviewing this situation.

- The rear middle seatbelt became locked and will not unwind or extend. The seatbelt remained stuck in the retracted position, making it unusable. The vehicle and seatbelt assembly are available for inspection upon request. However, Tesla has already fixed the issue, but I feel we were wrongly charged because I believe this should be a recall. I searched this issue online, and others have reported the same issue. Because we rarely have the need to use our rear seats, it wasn't until years later we discovered this issue. - Because the rear middle seatbelt cannot be extended, that seating position cannot safely be used. Any passenger sitting in that position would not have a functioning restraint system in the event of a collision, creating a safety risk. - Yes, Tesla service inspected the vehicle and confirmed that the rear middle seatbelt was locked and not functioning properly. - The vehicle has been inspected by Tesla service. It has not been inspected by police, insurance representatives, or other third parties. - No warning lights, alerts, or messages appeared prior to discovering the issue. The seatbelt was found to be locked when we attempted to use it, and it would not extend.

Safety restraint warning in car, unsure of actual issue but warning keeps popping up. Presumed that the seatbelts or airbags would not properly work in event of a crash. Dealer/company says it's a known issue, with other cars needing a fix too, however they aren't able to specify exactly the issue or issue a timeframe on repair. Issue first started appearing in Late August of this year, and has become more frequent as of recent. Potentially this is a critical safety issue regarding airbag/seatbelt's potentially failing to work as designed for all similiar models.

Driving a 2018 Tesla Model 3, driver seat shows message "Front left safety restraint system issue. Service is required". This occurs when the driver is in the seat with the seat belt fastened and the vehicle is in motion. This issue refers to the possible seat belt, seats and/or air bags failure. This is a threat for drivers as these are the front line of defence in case of any collisions or accidents. This issue has been reported by multiple Tesla car drivers and their posts are available on online forums. Message appears on the Tesla screen driven. Tesla does not cover this out of warranty. My appeal to NHSTA is this is hazardous to drivers and cars should be recalled and repairs should be covered.

The contact owns a 2018 Tesla Model 3. The contact stated that when the vehicle was started, the front passenger's side restraint warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with a seat belt restraint failure. The contact was informed that the front passenger's side wiring harness needed to be replaced. The vehicle was not repaired. In addition, the contact stated that a year prior to the failure, the front driver's side restraint failed, and the vehicle was repaired. The contact stated that at that time, the front passenger's side restraint failure was intermittent; however, the repair for the front passenger's side restraint was not completed because the failure was not duplicated. The contact stated that only the driver's side wiring harness was replaced under warranty. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 60,000.
