ALSO Now the THE TAIL LIGHT IS OUT AND NO WAY TO REPAIR IT NO ONE HAS THE LIGHT. Also this car is on its third transmission
The impact was severe enough to total my vehicle, yet no airbags deployed, and no forward collision warning or crash sensor systems activated. This is especially concerning because this vehicle was previously involved in a front-end collision (not my fault) and underwent extensive repairs.
The contact stated that while driving at an undisclosed speed, the Forward Collision Avoidance sensor failed to function as intended. The contact stated that the failure occurred while exiting a parking space. The contact stated that the images on the screen displayed a wider distance between the two vehicles.
Air bags never deployed . My car is totaled. The driver’s car hit so hard the front of her car was in my third row of seats. I was taken to the hospital for chest pains since the seatbelt was the only thing that saved me .
The contact stated that while his wife was driving at 25 MPH, the vehicle lost power steering. The vehicle failed to turn and crashed into a tree. There were no reported injuries. There were no warning lights. The contact stated that the failure was related to NHTSA Campaign Number: 21V455000 (Steering).
The air bags did not deploy. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the ABS. The vehicle was not repaired. A police report was not filed, and no injuries were reported. The manufacturer was not notified of the failure.
