Three problems related to engine and engine cooling have been reported for the 1998 Cadillac Deville. The most recently reported issues are listed below.
Customer was driving vehicle down road, all of a sudden coming up to a stoplight car suddenly died, at the same time white smoke came billowing out the back of the car, it caused a traffic hazard in which nobody could see her car, she was rearended, as well as the guy that rearended her. The occupant of the vehicle that rearended her ended up getting his nose broken when he hit his steering wheel. Vehicle taken to dealership and was determined that the rear head bolts had pulled from the block causing the head to separate from the block of the vehicle, quoted $4500 to repair and was told they could not warranty repair because it is a northstar engine. Vehicle then brought to me to get it repaired.
One night my family and I were driving my 1998 Cadillac Deville, and all of a sudden the heater coil burst without warning, the heater was not on and the car was not running hot. The car filled with steam making it impossible to see anything, and hot scalding water and anti-freeze poured out from under the dash board right over the gas peddle and scalded my right foot causing serious burns and leaving horrible scars. Luckily we were traveling on a country road with little to no traffic. I am relieved that me nor my family was seriously injured other than my foot being burned. Car dealer was notified, and nothing was done. I feel like this is a very dangerous matter that should be looked into and have something done about it.
