Consumer Description

I was driving on I39 north of Madison WI this afternoon, it was a clear day with light traffic and early afternoon on adaptive cruise control when the car on two occasions braked hard for no apparent reason. This braking would be a serious safety concern if a car had been behind me, as they would not have anticipated me braking so severely for no reason. From my reading this is a known problem with this car.
