What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
When he was in driveway, he claims he was on the brake when the car suddenly accelerated on its own. It destroyed the garage door and then went through the garage destroying property, the attic staircase, and the frame of an interior wall into a bedroom. We have pictures of the damage.
When I turned on the car this morning, the instrument cluster screen was black and would not activate. Because of this, there was no way to determine speed or to utilize driver assistance functions. This created significantly unsafe condition because I had no gauges or dials to assist.
On several occasions the vehicle aggressively stopped and jerked as if someone hit my car from behind. I took it to the dealership and they thought it was a software malfunction issue, since there were recalls on the vehicle.
The contact stated that on two occasions while driving at various speeds, the vehicle stalled. The contact stated that an unknown message was displayed. The vehicle was restarted after the first failure.
No warning lights were illuminated. The vehicle was taken to the dealer, who informed the contact that the battery charging capacity could be expected to decline by up to 40% during the winter months. The vehicle was not repaired. The manufacturer was notified of the failure but did not assist.
