NHTSA complaint #11739045

Owner complaint summary

Regarding the adaptive cruise control, sometimes the system won't engage. The first time this happened a warning popped on the screen saying something about seatbelts. I've learned that the problem can be "fixed" by pulling off the road and turning the car completely off. That includes opening a door to silence the radio. The cruise has always worked afterwards. Sometimes while driving on cruise control, in a straight line, the car brakes abruptly for no apparent reason. Granted we were on the interstate and there was traffic but no reason whatsoever to brake. The cruise control is easily confused on roads with multiple lanes and sharp curves, like on [XXX] between Asheville, NC and Knoxville, TN. The car will brake abruptly, seemingly sensing a car in front of me but in a different lane. Sometimes when reengaging cruise control the speed goes not to the speed I had set but what it "sees" as the posted speed limit. This caused the car to speed up in a construction zone and slow to a speed below the prevailing speed of traffic around us.
