2023 Tesla Model Y Seat belts Problems

I lease a 2023 Tesla Model Y. The rear passenger side seat belt/buckle assembly had previously experienced issues involving unexpected disengagement/unlatching. The vehicle was previously brought to Tesla for service regarding the restraint system/rear passenger buckle area and Tesla represented that the issue had been addressed. On April 4, 2026, during an emergency braking event to avoid another vehicle that abruptly cut in front of me and slammed on its brakes, I was forced to brake hard and maneuver to avoid a collision. During that braking event, the rear passenger side buckle released/unlatched while my child was properly secured in a child safety seat in that seating position. As a result, the entire child safety seat violently pitched forward and my child’s face struck the seat in front of her. This incident occurred after Tesla had already been given notice of restraint system concerns involving this seating position and after prior service attempts. The issue raises serious concerns regarding rear passenger restraint integrity and child occupant safety during emergency braking situations. Tesla was formally notified again regarding this incident on May 12, 2026. As of the date of this complaint, approximately one week has passed and Tesla has not responded or attempted contact regarding the reported child occupant restraint failure. The vehicle has not yet been reinspected by Tesla following this incident and remains available for inspection. I am requesting preservation of all vehicle telemetry, restraint system data, diagnostic information, and service records related to this vehicle and prior restraint system complaints/repairs.

Vehicle: 2023 Tesla Model Y Long Range Complaint: I am reporting a serious safety issue involving a vehicle sold by Tim Dahle Nissan Murray in Murray, Utah. Approximately three weeks ago, I purchased a 2023 Tesla Model Y Long Range from this dealership. After purchase, I discovered that the rear seat belts were not functioning. I have evidence indicating that the dealership was aware of this defect prior to the sale. This is a critical safety issue, as seat belts are required safety equipment under federal motor vehicle safety standards. The vehicle should not have been sold in this condition. Additionally, the vehicle had an issue with the right rear wheel/tire losing air. When I returned to the dealership, they failed to properly inspect or repair the issue. Instead, they reduced the air pressure in the other tires to match the leaking tire, rather than addressing the defect. After leaving the dealership, the tire again lost air. Upon inspection by another service provider, the wheel rim was found to be bent. When the tire was inflated to proper pressure, it began leaking air immediately. This created an unsafe driving condition, as the vehicle could not maintain proper tire pressure. I was forced to have the vehicle repaired by Tesla at my own expense ($1,390). The combination of non-functioning seat belts and an unsafe wheel condition placed my family, including my newborn child, at significant risk. I am requesting that this matter be investigated as the dealership knowingly sold a vehicle with defective safety equipment and failed to properly address additional safety-related issues. Also a police report was filed but I do not know how to get ahold of that it was filed with the Murray police department

Rear seat belt latch won't latch. This becomes a problem because dirt and debris fall into the seat belt latch since the seat belts latches are lower than the seat cushions. Child eats something with crumbs and the crumbs fall into the seat belt latch. Over time these build up to the point the seat belt won't click in.

Safety complaint: intermittent uncommanded rear-seat folding while driving; rear (3rd-row) seat belt anchorage integrity. Issue 1 — 2nd-row right seat: Since the purchase, the right-most rear passenger seat in the 2nd row intermittently activates its seat-folding motor while the vehicle is moving. In each event, a passenger was seated in that seat with the seatbelt fastened. The motor engages (audible whirring), and the seat attempts to fold fully forward; the passenger’s body prevents a complete fold, so the seat partially collapses while occupied. This has never occurred when the seat is unoccupied. The most recent documented event times provided to the manufacturer for electronic log review (CST): • Fri Jan 23: 7:40 AM; 7:41 AM • Mon Feb 2: 7:26 AM; 7:29 AM; 7:53 AM; 7:54 AM The manufacturer requested these exact times to check vehicle logs, but reported they could not find evidence in the logs and could not reproduce the issue during service/test drive. Issue 2 — 3rd-row seat belts: During a service visit on Feb 3, 2026, the manufacturer found that the 3rd-row seat belt anchors were not secured to the vehicle (documented as a safety concern) and performed a repair/adjustment to secure the left 3rd-row seat belt, then validated its operation afterward. The manufacturer had also previously documented (March 17, 2025) that the 3rd-row seat belts were not properly mounted and were unsafe/operational for passengers, but took no action in March 2025. No crash, fire, or known injuries to date. Request to NHTSA: Please log and review this as a potential safety defect involving (1) uncommanded activation of a rear seat-folding mechanism resulting in partial seat collapse while the seat is occupied and the vehicle is moving, and (2) rear (3rd-row) seat belt anchorage/installation integrity, based on recurring real-world events and manufacturer service documentation.

Subject / Issue: Driver Seat Belt Failure – Safety Restraint System Defect VIN: [XXX] Vehicle: Tesla Model Y 2023 Complaint Description: On November 11, 2025, at approximately 10:00 PM, while driving near my home, the driver seat belt cable snapped, leaving only the shoulder strap functional. This occurred under normal driving conditions, with no accident, impact, or misuse. The vehicle was then parked at my residence at [XXX] , and the failure made the car immediately unsafe to operate. The driver seat belt assembly and anchor points are part of the federally regulated Safety Restraint System, covered under FMVSS 209 (Seat Belt Assemblies) and FMVSS 210 (Seat Belt Anchorages). A functional seat belt is critical to occupant safety in any collision, and this defect directly compromises the primary safety system of the driver. Immediately after discovering the failure, I contacted Tesla Service via the Tesla App. My initial communication explained that the seat belt cable had snapped during normal driving, leaving only the shoulder strap, and requested immediate escalation to a Service Manager and replacement of the entire seat belt assembly. Tesla acknowledged receiving my vehicle at their service center (7077 W Sahara Ave, Las Vegas, NV 89117) but did not provide a repair under warranty. In multiple follow-up communications with Tesla Service (including with Efrain), I emphasized that this is a serious Safety Restraint System failure, federally covered under FMVSS 209 and 210, and that it was not caused by user damage. Despite these repeated notifications and requests for escalation, Tesla Service refused to repair the seat belt under warranty, citing Owner’s Manual exclusions and limitations, and insisted that the repair would be an out-of-pocket expense. Tesla provided no written justification explaining how a federally covered safety restraint component could be excluded from warranty. The vehicle remains at t INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The panel covering the driver seatbelt popped open & now the seatbelt position cannot be adjusted correctly. It appears as if the track holding the seat belt behind the panel is loose /rattling and the seatbelt system may need to be tightened down. I immediately contacted the dealer/manufacturer & Tesla wants 17 days to simply look at the issue.

Whenever the temperatures drop below 40 degrees, the driver seat belts stops functioning properly. Have to pull several times before the seat belt strap can pull all the way to be clicked on. Once seat belt is locked in place, while driving the seat belt feels like it could choke me. Once temperatures are normal, the seat belt operates normally. Also, the rear center seat belt intermittently will not lock in place. Have already reported these issues to Tesla and waiting for them to schedule the car for service at their service center.

This incident occurred repeatedly during travel from 6/28/2024-7/2/2024, the last time we had a passenger in the seat of interest. The right rear seatbelt kept tightening around the passenger to the point of extreme discomfort and eventually interference with breathing. The only resolution was to unfasten and refasten the seatbelt. The tightening effect occurred when the passenger adjusted her body in the seat or when the car experienced even minor bumps in the road. This repeated in a short cycle, approximately every 5-10 minutes, causing such irritation as to force the passenger to travel without the seatbelt buckled, despite repeated attempts to make the seatbelt operate correctly. This is obviously extremely unsafe--and illegal in many states, and in some cases negating insurance coverage, etc. Although this particular incident occurred in the vehicle noted earlier in this form, it also occurred in our 2015 Model S Tesla (now sold) on the right front side and in our currently owned 2018 Tesla Model 3, also on the right front side. We reported the original occurrence of the problem (Model S) to Tesla several times, and they inspected the seatbelt. There conclusion was always the same, as they stated to us, that the seatbelt was operating correctly, by design. We tired of reporting the issue. I know for a fact that for a correctly operating seatbelt, it may momentarily lock when bumps occur, then the lock releases. The seatbelts are available for inspection on request. There were no warning or error indicators presented in the car except the standard indication when the seatbelt was unfastened (intentionally).

Vehicle displayed error that service was required for front passenger safety restraint system fault in late September 2024, which persisted for several days. Customer immediately booked first available appointment booked with Tesla service center (3 weeks wait to mid October 2024). At dealership appointment, Tesla service advised it was unable to diagnose any problem because the error code had since cleared from the vehicle computer. Technician refused request for a manual inspection of the vehicle safety system. Technician refused to give paperwork or any form of documentation of the visit, insisting that the problem would be notated in Tesla's "internal service records" should Tesla need to review it at a later date. Subsequently customer received a "Service Appointment Cancelled" email notice from Tesla.

Rear passenger side seatbelt stopped working. It clicks when it is inserted and immediately becomes loose. It does not hold up and creates a serious safety issue. I have seen many people reported this issue online in Model Y Teslas. Nearest appointment Tesla provides is 2 weeks away and the seat cannot be used due to non working seat belt. I have never seen a seal belt malfunctioning in my entire life. It has happened many Tesla owners and these seat belts are not safe.

My vehicle is less than a year old and still under warranty. The dashboard display is showing the following error message: “front passenger safety restraint system fault”. Tesla informed me that the occupant classification safety system filter module has failed and must be replaced. Tesla has agreed to fix the component under warranty, but they informed me they could not schedule a repair until October 31. It is my understanding that damage to this component could prevent the airbags from functioning properly during an accident, so I am concerned that the car is not safe to operate with passengers. I have asked Tesla repeatedly if the vehicle is safe to operate and they refuse to answer the question.

What component or system failed or malfunctioned, and is it available for inspection upon request? >>> The passenger detection hardware underneath the front passenger seat had faulty wiring. The repaired hardware completed by Tesla this week is available for inspection upon request. I did take amateur photos of my seat hardware before-and-after repair. How was your safety or the safety of others put at risk? >>> MY PASSENGER'S AIRBAG COULD RANDOMLY FAIL IN THE MIDDLE OF A DRIVE. Anywhere from 10 seconds to 10 minutes while driving with a damp passenger in the front passenger seat (e.g., a 100 lb. person after swim practice), a red airbag indicator will assert with error code rcm2_a636 ("Front passenger safety restraint system fault"). The indicator would stay asserted for days, then start toggling on-and-off randomly. According to Tesla Model Y documentation, "If the airbag system detects a fault in any of the previously mentioned components, the airbag warning indicator stays on. In this case contact Tesla service immediately. Do not drive the vehicle until the airbag system is inspected by Tesla." (reference: [XXX] ) Has the problem been reproduced or confirmed by a dealer or independent service center? >>> YES! I was able to reproduce the problem WITHIN MINUTES with the loaner Model 3 given to me by Tesla (sorry, I did not get that vehicle's VIN but I wager Tesla Ridgepoint Austin TX has it). SURELY THERE ARE TENS OF THOUSANDS OF VEHICLES WITH THIS PROBLEM! Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? >>> Yes, but only after three attempts by Tesla. Each attempt was incremental (first: cable shielding, second: upholstery, third: replace the entire seat). Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? >>> No. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
