Example complaints

Forward collision avoidance: “Vehicle aggressively and without cause engaged the Automatic Emergency Braking System causing the driver to be slammed against her seat belt and almost having the car in back of us to almost rear end our vehicle. This has happened in the past but it has been a manageable slight deceleration when going around a gentle curve or at the railroad overpass. . This time the incident was intense almost causing a rear end collision. I would add that this severe incident happened when approaching the same railroad overpass in the rain. This has also happened at this intersection in good weather. …”

Other or unknown: “Sunroof shattered while driving. If I did not have sunroof cover closed, glass would have fallen on me into car and potentially cause distraction leading to crash. An insurance rep will be inspecting vehicle within the next 3-5 days. No prior warnings before glass shattered.”

Back-over prevention (rear camera): “While waiting in a parking lot, I was reviewing the settings available on the lower center display, one of those options was for Camera. Inside this menu I found and made adjustment for options like brightness, contrast, tint, color, and black level... and while most of those seemed to work well, and I was able to make suitable adjustments to the camera--the tint and color options seemed to have no effect on the image. So, I opted to adjust tint from the default/middle value all the way to the left/lowest value and save the settings. …”

NHTSA complaint #11534464, filed 2023-07

Brakes: “The brakes automatically engage without cause. The problem occurs at both city and highway speeds, from 20-75 mph. It is particularly bad when passing underneath a bridge. The car will abruptly stop. This has been ongoing for monthes. Sometimes, the vehicle will act inappropriately when the brake is applied by the driver. The car will attempt to accelerate. Other times the car will hard brake as if slamming the brakes.”
