The smart brake system is malfunctioning. The car slams on its brakes for no reason. No vehicle is ahead of me. I have been driving at highway speeds when this occurs and I haven't been rear ended yet. It's happened numerous times before and after I completed the recall. The condition is worse when it's raining. The car has been at the dealership for over 30 days unable to repair.
