NHTSA lists 2 safety recalls and 95 owner complaints for the 1997 Cadillac Seville. Most complaints involve engine and engine cooling (19) and fuel system, gasoline (17). The EPA rates it 18 mpg combined.
SOME PASSENGER VEHICLES EQUIPPED WITH 4.0L V8 ENGINES HAVE A CONDITION IN WHICH THE NYLON TUBING USED IN THE FUEL RAIL CONSTRUCTION MAY DEGRADE AND CRACK. ADDITIONALLY, THE 1995 MODEL YEAR USES A UNIQUE UNDERHOOD FUEL RETURN LINE THAT MAY CRACK. CRACKING OF THE FUEL RAIL OR RETURN LINE TUBING CAN RESULT IN A FUEL LEAK INTO THE ENGINE COMPARTMENT.
THE ELECTRONIC BRAKE CONTROL MODULE OR THE ELECTRONIC BRAKE AND TRACTION CONTROL MODULE CAN CAUSE THE ANTILOCK BRAKE SYSTEM (ABS) TO CYCLE DURING A NON-ABS BRAKE APPLICATION.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“TL*THE CONTACT OWNS A 1997 CADILLAC SEVILLE. THE CONTACT STATED THAT THE VEHICLE WAS LOSING COOLANT (MANUFACTURER RECOMMENDED) AT A VAST RATE. HE HAD TO REPLACE THE COOLANT IN THE VEHICLE ALMOST EVERY OTHER DAY. IN ADDITION, THE HEATING GAUGE WOULD SPORADICALLY MOVE. HE TOOK THE VEHICLE TO THE DEALER, BUT THEY COULD NOT DETERMINE THE CAUSE OF THE FAILURES. THE DEALER IS CURRENTLY PERFORMING DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT NOTIFIED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 110,000.”
“HIT A SPEED BUMP - LOUD NOISE - COULD BARELY BRAKE - AVOID COLLISION AND AFTER EVENTUALLY BEING ABLE TO STOP; LOOKED UNDER CAR AND FLUID GUSHING OUT LIKE A RAINSTORM. CALL INSURANCE COMPANY WHO STATED IT WAS A COLLISION; HOWEVER, REPAIR SHOP AND ADJUSTER FOR INSURANCE COMPANY STATED IT WAS BOUND TO HAPPEN DUE TO RUSTING AND CRACKING OF BRAKE LINE, ETC. AND WILL NOT PAY FOR REPAIR - AUTO REPAIR DID SEND A PAPER SHOWING A RECALL THAT WAS ISSUED BY NHTSA ID: 04V110000 ON JUNE 2, 2004 DEALING WITH FUEL SYSTEM AND THE FUEL RAIL CONSTRUCTION WHICH MAY DEGRADE AND CRACK. I INFORMED NOT ONLY THE INSURANCE ADJUSTER AND THE REPAIR SHOP, AND I ALSO CALLED CADILLAC AT L-8---458-8006, ABOUT THIS RECALL AND SINCE I NEVER RECEIVED A RECALL FROM CADILLAC, IT WOULD APPEAR THAT THIS IS AN ISSUE WHICH SHOULD BE ADDRESSED BY THEM. I THANK YOU FOR YOUR ASSISTANCE. *TR”
