1999 Cadillac Deville. Consumer states that the vehicle persistently overheats and the engine shuts off. The consumer stated the vehicle was leaking coolant. The thermostat, upper radiator hose and reservoir were replaced. A diagnostic test revealed exhaust was entering the coolant system and the vehicle would emit smoke of any color.

The contact owns a 1999 Cadillac Deville. While driving at an unknown speed the vehicle stalled. The dealer performed a diagnostic evaluation of the vehicle and located a coolant and water pump leak, as well as engine failure. There was pressure build-up and head gasket failure, which contributed to the failure. The dealer estimated that the repairs would cost over $3,000. Although there was a customer safety improvement campaign, the manufacturer denied the contact's claim due to the current mileage on the vehicle and because she was not the original owner. The current and failure mileages were less than 86,629. Updated 04/29/30.

While driving vehicle reached high temperatures. Had radiator replaced and thermostat. The car still overheats. Took the car to technician who suggested to replace the engine which would cost $7,000. Through online research, my daughter discovered the Cadillac Deville 1999 northstar model/vehicle has numerous issues due to overheating and head gaskets.

While sitting in front of my home my 1999 Cadillac Deville caught on fire and burnt to a total loss. The car was parked, had not been driven for about 48 hours. The fire started in the engine compartment. The fire occurred at about 2:00pm. Satruday afternoon. Temp about 82 degrees. Something in the cars engine room on the left side ignited. It appears to have been an electrical problem that self ignited. Just prior to the fire, my wife who was at home at the time heard the car alarm go off. She went to the window and it quit sounding. She did not see any fire at that time. About 5 minutes later a neighbor pounded on the door and alerted her to the fact that the car was burning. The fire was so intense that before the fire department got to the seen, one of the hood gas struts blew through the front grill and landed about 20 feet in front of the vehicle. The fire department came and put out the fire. Something obviously within this cars engine compartment electrical/computer system started the fire. The car is a total loss. Cadillacs should not burn and should not spontaneously ignite. The car had about 75,000 miles. I own 11 other cars and have a small car collection. I am a car guy and this car like all my cars (including 2 ferrari's) has been well maintained and when I last drove on Thursday evening August 28, it ran fine and did not give me any indication of any electrical issues. The police determined that it was not vandalized or caused by any outsiders.

The contact owns a 1999 Cadillac Deville. The contact stated that the vehicle would overheat. He took the vehicle to the dealer and they replaced the water pump. The failure recurred and the contact was informed that most of those model vehicles were designed to operate in that manner, and it was safe to drive. A few days after the water pump was replaced, while driving 70 mph, the vehicle began to excessively overheat. The contact shut off the engine and had the vehicle towed to a mechanic. He was informed that the cause of the failure was not the water pump, but rather a blown out head gasket. The vehicle cannot be repaired without a new engine. Through online research, he discovered that his model vehicle has numerous issues due to overheating and head gaskets. The vehicle has not yet been repaired. The failure and current mileages were 74,000. Updated 07/08/08. Updated 07/08/08

While starting vehicle engine backfired. Then fire started coming from under the hood. The under hood padding was covered with a flammable material. This caused the fire to burn through the paint on the outside of the hood.
