While driving on [XXX] I was in traffic, Car ahead of me was 2 Car lengths ahead, emergency Brake slammed on! I had put my foot lightly on brake to slow down to keep safe distance! We were violently thrown forward( unexpected stoppage) . Car in back had to slam on its brakes and swerve off Road to keep from hitting us! This has happened about 4 times. I have taken Car to dealer and they keep saying there is nothing wrong with the Car! The Service guy who I am assigned to told me to cut off the Braking system. If itâs not safe why do the keep it on the Car and sell it! I am afraid to drive the Car for fear I will be killed or injure somebody else! The Service dept does not note what I brought Car in for on my service history, this is deceptive record keeping! Claiming I brought Car in for other services, when I clearly complained about the Braking problem! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
