What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There were no known warning lights, messages, or abnormal symptoms immediately prior to the failure. The wheel separation occurred suddenly without prior indication.
The vehicle continued down the driveway & crossed the street, hitting a fire hydrant in my neighbor's yard across the street. I never physically got into the vehicle to do the steps required to put the vehicle into reverse, i.e. putting my foot on the brake & depressing the transmission shift button.
The car was involved in an accident, after the shop checked the vehicle it was brought to our attention that the air bags got stuck and did not deploy because of a malfunction. I was not aware of this which it could put my son in really dangerous situation.
There was an incident on January 13, 2022 due to a manufacturer defect that caused my car to accelerate on it’s own. I was parked at a car wash to vacuum my vehicle.
The air bags did not deploy. The contact's son was not injured as a result of the accident and did not seek medical treatment. The police were not called to the scene and a report was not filed. Due to the failure, the vehicle was towed from the scene to an independent auto repair shop.
Unintended acceleration. Pulling into a parking space in a shopping center parking lot, after going over a speed bump and making a left hand turn into the spot the car accelerated and would not stop. Pushing on the brakes did not work.
