Owner report 10153775 · 2006-03-27 (March 27, 2006)

VEHICLE SHUTS DOWN AT CRUISING SPEEDS, LOW SPEEDS, AND IDLING. ALL SYSTEMS SHUT DOWN WITHOUT WARNING. VEHICLE MAY OR MAY NOT START BACK UP IMMEDIATELY. I HAVE SEEN SEVERAL OTHER COMPLAINTS ON SAME ISSUE BOTH ON NHTSA AND OTHER CHAT BOARDS. THIS CAUSES A HAZARDOUS DRIVING CONDITION FOR MYSELF AND OTHER DRIVERS. CAN BE ESPECIALLY DANGEROUS ON HILLY AND CURVED ROADS BECAUSE ALL POWERED STEERING AND BRAKING SHUTS DOWN AS WELL. *JB

I BOUGHT A 1999 CADILLAC STS FROM A DEALER IN MORGANTOWN, WV. IT WAS A COUPLE OF YEARS OLD. NOW, IT HAS ABOUT 124,000 MILES ON IT. AFTER A FEW TRIPS TO THE DEALERS SERVICE DEPARTMENT RECENTLY, I WAS TOLD THE REASON MY CAR WAS RUNNING ROUGHLY WAS BECAUSE THERE WAS A LEAKING HEAD GASKET. UNFORTUNATELY, THE DEALER SAID, THEY WON'T TRY TO REPAIR IT BECAUSE THEIR EXPERIENCE WITH THE CADILLAC NORTHSTAR ENGINE IS THAT IF THEY TRY TO REMOVE IT, IT STRIPS SOME SORT OF BOLT OR THREAD, RUINING THE ENGINE. I HAVE BEEN IN TOUCH WITH CADILLAC BY TELEPHONE AN…
