What owners say about the power train

Verbatim from NHTSA complaints, newest first
“On 10/8/26 My vehicle failed in the middle of traffic as I was driving the car forcefully slowed down. When I proceeded to press the gas the car began driving in reverse putting me in immediate danger causing 2 different car to almost hit me from behind. I put the car in park , turned on my hazard lights and got out of the vehicle . I called my husband immediately luckily I was not far from home, and had him push my car out of the street . It’s currently still there.”
