“On three separate occasions, while going very fast (60-78 mph), the automatic emergency braking system turns on. The warning lights flash and there is some type of warning noise. I don't even know if it starts to break because it scares me so much, I just press the gas. It turns off within a couple of seconds, but that is not the point. If I didn't react so fast, I am unsure of what could actually happen.”
NHTSA complaint #11627928, filed 2024-11“The forward collision warning, automatic emergency braking and adaptive cruise control failed as the first 2 activated when there were no oncoming collisions in front of me and the nearest cars around me were 1/4 of a mile away. The cruise control failed as it turned back on after the vehicle veered off the highway and into the rest stop. My safety and the safety of a lot of other people in the rest stop were put at risk because the system malfunction and tripped when no other cars were present that would have led to a collision. …”
NHTSA complaint #11508517, filed 2023-02“The vehicle has been turning completely off after use for over a year now. At first it would happen every now and then at the beginning and all you'd have to do was restart the car manually. Now every time the car is turned off it needs to be restarted manually now. The car will also shut itself off while you are driving. It will tell you something is wrong and then won't let you get over 15-20 MPH. If you are on a neighborhood, it's less dangerous for this to happen where you can pull over and turn off the car and restart it. …”
