What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
No warning lights were illuminated. The air bags failed to deploy. A Police report was filed. The vehicle was towed to an auto body shop. The contact sustained injuries to the left shoulder and arm. The driver in the other vehicle sustained unknown injuries. Both drivers required medical attention.
In the process of parking, vehicle was stopped in the parking spot and vehicle suddenly accelerated to a high speed and crashed into a brick column. Air bags did go off. The warning sound and diagram that indicates you may have gotten too close to the curb in front did not go off.
During the incident front and side curtain air bags did deployed. Driver sustained an injured sternum and bruses and lacerations to both hands. The front passenger suffered a bruised sternum. both rear passenger sustained mild neck injuries. No medical treatment was provided. No police reported was taken.
But instead of creeping forward as normal, the vehicle suddenly jerked forward approximately one foot. In the first of two incidents (approx. October 2025), it crashed into the car in front of me. In a second incident (3/14/2026), it crashed into an EV charging station.
I was slowing down to park the car when it lurched forward in high speed and smashed into the wall. The front collision warning never went off, and the emergency braking never came on.
The contact stated that her husband depressed the brake pedal several times, but the vehicle did not slow down, and the steering wheel locked, preventing the driver from steering the vehicle to safety. The vehicle then crashed into the back of another vehicle that was either stopped or was moving extremely slow.
Although I maintained an adequate stopping distance from the truck in front of me, my forward collision warning, lane departure warning, and lane keeping assistance systems suddenly activated, causing my vehicle to make contact with the truck. My safety—and the safety of others—was compromised.
I was driving at 35 mph when the front doors began unlocking and locking rapidly three times, then both front doors fell open ajar, at the same time the screen went grey with a triangle !
