What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

My son was making a left onto a freeway on ramp after traffic cleared and the steering wheel completely locked up resulting in him going over the curb and rolling completely over in a steep ditch. This occurred at a low speed (no more than 25mph), confirmed by the Life369 app. My son's description was that it felt like the wheels were against a wall and the wheel wouldn't turn even though he was using both hands in an attempt to turn.

June 2025 CrashInjury

The problem with this car that continues is that when driving over 65 miles per hour/ more or less, the driver side door rattles and shakes. It rattle and it looks like if the door wants to detach. It only happens on the driver side, not the passenger side. I put my arm on the arm rest, and my arm shakes and that is not ok. I am concern and want to know what can be done about it. I do not feel comfortable driving when this happens and its a new car, it should not have this problem.
