Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“On 7/18/2023 - my car reported the following: Replace Occupant Classification System (OCS) of Front Passenger Seat. In essence the seat sensor on the car malfunctioned and needed to be replaced. Tesla charged me $466.29 to replace this and said that this was not under warranty, even though this was a safety issue on their part.”

NHTSA complaint #11533222, filed 2023-07

“I have an alert that says Front Passenger Safety Restraint System Issue and Service is required. This is a major safety issue and the Tesla Service Center says I need to pay $800 to fix it. This is a manufacturer issue and the cost should not be incurred by the vehicle owner. This issue puts my family safety at risk and the light is coming up everytime I drive. I need TESLA to review it and fix this at no cost.”

NHTSA complaint #11682933, filed 2025-08

“2 of 3 backseat seatbelts suddenly stopped latching, middle seat, and driver side rear seat. These are the seatbelts we use the least in this vehicle. Yes, the dealer replaced the 2 failed seatbelts, but would not replace all seatbelts in the vehicle. The vehicle was only inspected and fixed by Tesla. No, there were no warnings. This is especially concerning since we use a seatbelt to secure a car seat in the backseat.”

NHTSA complaint #11580774, filed 2024-04

“One of the rear seat belts will not latch. The buckle will go about 3/4 of the way in, but will not latch completely. It feels like there is something preventing the buckle from inserting compeltely. This puts our family at risk because one of our children cannot buckle their seatbelts when riding in the car. This has been present since we bought the car; it was delivered to us on August 11 and was not functioning upon delivery.”

NHTSA complaint #11609194, filed 2024-08

“The seatbelt latch in the back center seat is not working. I tried cleaning it out and no debris is in there and it still won't latch. Tesla doesn't have availability for a month for this safety issue. I have three young kids.”
