While turning into a parking spot in a covered parking garage the car seemed to speed up and lurch. It hit the cement wall and pushed the car back with such force the air bags deployed. Thank God it was just a wall. The car is now at the repair garage and have not heard back regarding how much damage and if the car is going to be "totaled". When I mentioned this at a party we were at, a friend of mine said she had the same problem. There were no collision warnings. It happened in a split second. The parking garage was at my Doctors office so I was able to have my wrist x-ryed right then. No serious injury. Just a little leary of driving this model car if not any electric vehicle.
Airbags did not deploy when vehicle hit 75 ft highway guardrail driving over 70 mph. The car was totaled, the driver's head hit the steering wheel, requiring stitches. EMS and police at the scene were surprised to find airbags not deployed. Vehicle has been inspected by insurance. Manufacturer has not yet been informed, to my knowledge. There were no warning lights or messages indicating a problem with airbags or anything else for that matter. Driver was wearing seatbelt.
I was T boned at an intersection by a red light runner. My car got hit on the driver side and front to back where the initial impact occurred by the left front wheel. None of the airbags deployed. My speed was probably around 30 miles and the other cars speed I don't know. The other car was a 2021 Toyota suv. I don't recall what model but all of the airbags deployed in the Toyota. I got thrown against the driver door and sustained an injury to my left rib cage.
My vehicle was in a collision on the freeway and the airbags did not deploy. The car is being assessed to see if it deemed totaled. Regardless of the outcome of the status of the vehicle, given the impact of the accident, the airbags should have deployed given the impact of the collision and the impact on the car.
Air bags did not deploy during crash. It is available for inspection upon request My face smashed into the steering wheel resulting in black eyes, swollen nose, cuts on my face and a concussion. Yes, the airbags clearly did not deploy during crash No No
I have an alert that says "Front passenger safety restraint system fault". I took the car in to Tesla Service in late April. Was told it would be about $270 to replace the sensor in the seat that detects it someone is sitting in it. They told me that when the parts people went in, that wasn't the issue and that to fix the sensor they thought it was they would have to tear the whole seat apart and that takes too long so instead I need to buy a whole new seat at the cost of $3000. I didn't have time to deal with it further at that point and the seat was back ordered anyway. I asked if the issue would affect the operation of the airbags or seat belts thus causing a safety concern and was told that it would not. That the car was still safe. I took the car back without repair. …
I have been getting an alert: Front passenger safety restraint system issue/Service is required. It has come on when there is no one in the seat and goes away shortly after I start to drive. I contacted Tesla and they sent an estimate to repair it which includes a bunch of different bolts, Passenger Airbag, Airbag Harmiss Retaining Clip. Also replacing Occupant Classification System (OCS) of Front Passenger Seat while Servicing Supcomponents. List of parts for that is First Row Seat Harness Assembly-Right Hand, First Row - Seat Belt Reminder Sensor Box Clip, First Row Occupancy. All of this will cost over $700 . Aren't these items required safety equipment that they should responsible to maintain? I have seen that there are a lot of other people having the same issue, I think that there should be a recall on this that they shoud have to pay for.
