My service active handling system warning came on abruptly. this the second time this happened in the last 2 years. the first incident was handled by my local dealer. supposedly, it was a tsb which required replacing a clip at an electrical coupling. this was reportedly the solution to this problem. this most recent incident occurred 500 miles from home and has me worried that a serious malfunction of my braking system may occur. i do have an appointment for service on june 4 2012 for this recurring issue. there have been reports of abrupt and inadvertant braking occurring at highway speeds with loss of vehicle control. help would be appreciated. thank you information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6) *tt
