What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated no warning light was illuminated. The air bags did not deploy. The contact stated she did not sustain any injuries and her daughter (front passenger side) was feeling dizzy but declined to seek medical attention. A police report was filed. The vehicle was not drivable.
The steering adjustment moves in and out but will not move up or down. You can hear a clicking noise like itâs trying to move but nothing happens to the steering column.
The warranty was previously extended on the system but I am outside of the mileage window but inside of the time window. I have $6000 in repairs so far and am trying to get assistance. I have been dealing with issues since October 2024
1. Windshield wiper assemblies failed to operate. 2. During severe rainstorm in Northern California, driver side wiper arm stopped working while I was driving on freeway. 3. Confirmed by independent service center. He showed me a broken part under the hood. He said it would cost close to $1000.00 to repair. 4.
The contact stated that the front passengerâs side air bag warning light failed to function as designed. The vehicle was taken to the dealer where the mechanic informed the contact that the sensor light was permanently disabled.
It started to smoke a gray smoke coming up from under the car on the passenger side of the car over the front tire. I do have pictures. It smells as if it is about to catch on fire. The car never had any problems before this botched repair. Now they say they cannot find the problem.
