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.

The contact owns a 1998 Cadillac Deville. The contact stated that while driving at various speeds the vehicle would stall due to the engine overheating. The failure would occur whenever the vehicle was in operation for a few minutes. During the failures, the engine overheat light would illuminate on the instrument panel. The vehicle was taken to an authorized dealer where the contact was informed that the freeze plug needed to be replaced. The vehicle was also taken to an independent repair shop where the contact was informed that the head gaskets were warped. The vehicle was not repaired. The failure mileage was 110,000 and the current mileage was 111,000.

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.

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 engines have problems. I'm trying to buy american made products but with problems like this it's getting difficult to do this. Hoping I can get some resolution to this problem.

: the contact stated the vehicle's oil and antifreeze leaked causing the intake and outtake of the engine to rust, in turn causing the pipe to bust and the vehicle to overheat. The vehicle needed a new engine to fix this issue. Updated 12.8/2006 - 4.6 liter northstar engine. The L/F window was inoperative. The brakes pulsated. The ses light illuminated. The headlight was inoperative. The automatic transmission failed.
