What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
It didn't work it didn't brake or didn't have an alert in which caused an accident
The autobody shop confirmed that the airbag sensors went off, but the airbags did not deploy. A claim was filed with my insurance company, and the airbags have been replaced by the autobody shop. The vehicle did not get back to the dealership.
The contact stated that after driving into the garage and while pressing the brake pedal, the vehicle suddenly experienced unintended acceleration, lurched forward, and crashed into the husband's workbench. During the incident, the brake pedal was forcefully pressed, but the vehicle did not immediately stop.
My side air bags did not deploy. There is structural damage and my front passenger tire is laid in this this wasn't a light tap on my car.
The air bags did not deploy. No warning lights were illuminated. A police report was not filed, and no injuries were reported. The vehicle was taken to an independent mechanic, who was unable to duplicate the failure and informed the contact that the incident recorder does not log data for incidents under 25 MPH.
After driving around in [XXX] we said it was unusually noisy inside so I said I would stand on the door sill to look at the roof and that’s when I saw the hole in the sunroof. That night, Sunday, XXX, I called our insurance company to report the damage. They said that an adjuster would contact us on Monday.
