Electrical system
45 reports4 crashes1 fire1 related recall
“The contact owns a 2002 Cadillac Deville. The contact stated that while driving approximately 7 MPH and making a left turn, the vehicle suddenly shut off, causing the driver to lose control of the steering and crash into a tree. During the crash, the vehicle sustained front-end damage, but no air bag had deployed. No injuries were reported, and no police report was taken. The vehicle was later towed to a local dealer, who diagnosed that the ignition switch had failed. The vehicle was not yet repaired. The manufacturer was notified of the failure. The contact was informed that the VIN was associated with NHTSA Campaign Number: 14V355000 (ELECTRICAL SYSTEM). The contact indicated that the vehicle had experienced the same failure listed in the recall. The failure mileage was 80,000.”

“MY CAR WAS PARKED IN MY GARAGE WHEN THE HORN SOUNDED EXTREMELY LOUD AND WOULD NOT STOP I COULD NOT STOP IT SO I TOOK IT TO SHOP. THE DEALER SAYS THAT AIRBAG SHORTED OUT AND SHORTED OUT THE HORN. THEY WANT TO REPLACE AIRBAG AND HORN AT A COST OF $1109 WAS THIS AIRBAG RECALLED?”

THE VEHICLE WAS TAKEN TO A DEALER WHERE THE TECHNICIAN DIAGNOSED THAT THE INNER HEAD GASKET NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE.

“I WAS GOING TO DROP OFF SOME TRASH BAGS IN DUMPSTER AROUND THE BLOCK FROM MY HOUSE.AND WAS PARKED NEXT TO IT AT APTMENTS STREET.I PUT THE CAR IN PARK TURNED OFF ENGINE AND REMOVED THE KEYS POPPED THE TRUNK REMOVED TRASH BAGS CLOSED TRUNK AND GOT BACK IN DRIVER SEAT PLACED KEY IN JUST AS ALWAYS REAL EASY GOING AND TRIED TO TURN IT FOR HOUR IN HOT SUN THEN WALKED HOME CALLED TOW TRUCK WERE WE BROUGHT IT HOME WERE I LIVE MY HOUSE AND COST $164.00 DOLLARS AND IS IN SAME CONDITION AS OF NOW. *TR”
Engine
17 reports1 crash
“TAKATA AIR BAG, DO NOT KNOW IF THAT ITEM IS IN MY CAR BUT THEY SAY IT IS. ALSO LIKE SO MANY NORTHSTAR ENGINES THERE IS TROUBLE WITH THE HEAD GASKET, AND ACCORDING TO THE HYDROCARBON BLOCK TEST, MINE MUST BE REPLACED. IN ORDER TO REPLACE IT, THE ENGINE AND POWER TRAIN MUST BE REMOVED, AT MY EXPENSE. DUE TO THIS ISSUE, MY CAR CONTINUES TO TRY AND OVERHEAT AFTER ABOUT 29 MILES OF DRIVING. AFTER LISTENING TO THOSE FOLKS ON THE CADILLAC FORUM, I HAVE BEEN LEAD TO BELIEVE, THE OVERHEATING ISSUE MAY BE, PARTLY THE FAULT OF THE FINE THREAD HEAD BOLTS AND OR STUDS. MANY MECHANICS I HAVE SPOKEN WITH HAVE SAID THAT I NEED A NEW ENGINE, ALTHOUGH THE FOLKS ON THE CADILLAC FOURM HAVE SAID THAT TIME-SERTS, OR THE LARGER STUDS/BOLTS MIGHT FIX THE ISSUE. NEVER THE LESS, WITH EACH CADILLAC DEVILLE DHS WITH THE NORTHSTAR ENGINE I READ ABOUT, THE SAME ISSUE EXISTS FOR ALMOST ALL OF THEM, WHICH INDICATES TO ME THAT THERE WAS AN ISSUE IN THE ORIGINAL DESIGN OF POSSIBLY NOT USING A LARGE ENOUGH BOLT/STUD TO BEGIN WITH. EITHER THAT OR CADILLAC MAY HAVE HAD A PLANNED OBSOLESCENCE TYPE THING TO GET THE DRIVERS TO KEEP REPLACING THEIR AUTOMOBILES. AND THEY SAY RECALLS ARE NOT COVERING THIS DESIGN FLAW....”

THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 120,000.”
