NHTSA Complaint #10577322 — 2013 CADILLAC ATS

ON FEBRUARY 22ND AND 27TH 2014, WHILE TRAVELING AT 75MPH THE ADAPTIVE CRUISE CONTROL SLAMMED THE BRAKES ON THEN RELEASED. I THOUGHT THE SYSTEM HAD MISS-READ THE SHADOW OF AN OVERPASS AS A VEHICLE IN FRONT OF ME BECAUSE THAT WAS THE ONLY THING IN SIGHT WHEN THE BRAKES LOCKED, THERE WERE NO VEHICLES PRESENT. ROADS WERE DRY. IT WAS REPORTED TO CADILLAC VIA THEIR 800 NUMBER AND THEN BROUGHT TO THE DEALERSHIP 4 MARCH 2014,FOR ANALYSIS. THE DEALER IMPLEMENTED AN UPDATE TO THE ACTIVE SAFETY CONTROL MODULE. CADILLAC STATED THEY WOULD SEND AN E-MAIL TO MY DEALER ABOUT THE PROBLEM, BUT DEALER STATED THEY NEVER RECEIVED THE E-MAIL. NO FURTHER PROBLEM NOTED UNTIL 1 APRIL 2014, FOUR WEEKS LATER, DURING A TRIP THE SAME ACTION HAPPENED TWICE WITHIN A MILE OF TRAVEL. BRAKES WERE ABRUPTLY APPLIED, RED SCREEN ON DASH WITH CRASH IMMANENT. AGAIN AT 70MPH AND NO BRIDGES OR OTHER VEHICLES IN PATH. THE ROAD CONDITION WAS WET. THIS IS A LARGE SAFETY CONCERN FOR ME IF THE BREAKS SHOULD LOCK AT 70+ MPH AND NOT RELEASE AND I HAVE TRAFFIC BEHIND ME. *TR
