NHTSA complaint #11498189

Owner complaint summary

In March/April 2020 I was driving at 65 miles per hour on a rural highway. The only vehicles on the road were my car, the pickup in front of me and the pickup behind me. Since the highway was so quiet, I decided to try Adaptive Cruise Control (ACC). I set it for 65 miles per hour (the speed limit). We had been driving for about 15 minutes, each car maintaining the same speed and distance. The pickup in front of me turned on his turn signal for a right turn and entered the right turn lane. As my car approached the pickup, in the turn lane, the automatic braking system activated. I lunged forward, the seat belt activated, braking warning was displayed on screen and there was an audible alarm. I managed to take control of the vehicle and to accelerate. I was afraid the vehicle behind me would collide with me. I turned off ACC and tried to regain my composure. When the pickup moved into the right hand lane, there was nothing in front of me as far as the eye could see; just open highway. I will never use ACC again. Yesterday, December 19, I was driving on a side street. I had just exited a school zone, speed limit 15, and my speed was now approximately 22, no vehicles in front of me just some cars parked at the curb ahead to my right. There was an audible tone and the word BRAKE displayed on the screen. The brakes did not activate.
