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...

I have a 1998 cadillac deville that I am putting the 3rd engine into the car due to a head gasket problem. My parents have the same car with the same problem. I have read classifieds that citizens who own the same car are forced to give the car away because of this head gasket problem. Anyone who can service this car (including a cadillac dealership) has admitted that it is a very common problem with this car, and that there is no financially reasonable repair, and replacing the engine is usually the only...

1998 Cadillac deville concours. Northstar 4.6L v8 I have made numerous complaints about the oil consumption of this vehicles engine. Only to receive the brush off from the dealership about gm's allowable northstar consumption. This engine is consuming 4 qts per month on average and is not acceptable in my book. What do I do now ? No manufacturers warranty or extended left to help and only 80,000 miles on this vehicle. I definitely believe that this vehicle was a lemon from the get go and that gm knows these...

FAILURE OF HEAD GASKETS AND MAIN SEAL LEAKING. 4.6L V8.

Vehicle overheated while driving at 45mph. Dealer notified. *Ak

Consumer noticed, excessive oil consumpsion every 3000 miles one quart of oil, causing engine stall very often. Dealer has been notified. Please provide further information. Ts

Dealer reports that this gasket failure is a common problem with the northstar engines and that the entire engine must be dissassembled to replace the gaskets. The failure allows excessive amounts of oil to leak out of the engine leading to eventual failure. The problem seems to be poor or faulty engineering of the engine. *Ak

Engine started "knocking" slightly, at cold startup, at appr. 39000 Mileage. Now sound has increased in volume and can be heard when cold or hot, idling and/or driving. I will take car to memphis cadillac. Note: I had same problem with new 1994 chev. Full size conv. Van. Returned van to dealer after 9 months ownership & 18 times to a dealers shop. Was diagnosed as loose rod bearings.*Ak

Not a safety defect but this car is leaking oil around the oil pan and from what I understand from the dealer that they have redesigned the rubber gasket to withstand hotter tempatures and I feel that this should be some kind of recall on this. The dealer is wanting $1800.00 To repair this and my car has only 58,000 miles on it.*Ak
