ENGINE AND ENGINE COOLING

 My father purchased a 1996 sedan deville brand new. he passed away in april 1998. my mother drove the car until this year. she gave me the car. the car has approx 17,000 miles. i just found out the car has a blown rear head gasket. i realize the car is 15 yrs old but i feel this should not have happened with such low mileage. the car was never abused and still smells new inside. do i have any recourse with gm?

 Car loses power completely and cuts off. there is no electric or engine available and the car must be restarted in order to proceed in traffic. this failure usually occurs at low rates (20-35mph) of speed but especially when turning corners. power steering is diminished due to power failure. *tr

 Very dangerous situation occurred while driving on city roads where posted speeds are 35-45 mph. the car just started to speed up on its own and i could not get the engine to slow down. the only way i could avoid a traffic accident was to ride the brakes continuously. by the time i got home the brakes were smoking and extremely overheated. i almost could not stop with the engine racing and the brakes worn out. i had to shut the engine down while still in drive, almost running into the wall of my house. i am 70 years old and was very scared. on edmunds .com there are three other reported instances of the same thing happening with the same make and model. my car is undriveable and i will have to get it towed from my house to the dealer for it to be checked out, please follow up on this as it is a very dangerous condition. i was very close to having an accident. *jb

 Loss of engine coolant on my 1996 cadillac deville. took car into dealer and they diagnosed blown head gaskets. repair called for engine removal and cost approx. $3400. i have heard of a number of other gm northstar engines having this same type of failure. my car has been dealer maintained since new and with only 85,000 miles on this car and the number of other similar failures reported, i consider this a manufacturers design fault.*jb

 I have a 1996 cadillac deville that i purchased new. at about 83k miles, i noticed that an oil leak had started from under the engine. i took it in to the dealer near where i live now (moritz cadillac in arlington, tx), and was told that the cause of the oil leak was the wearing out of the engine seals at the bottom of the engine. i was then told it would cost $1,800 to repair as it would require the complete removal of the engine from the car to repair (about 18 hours of labor). after some research on the web i found that this is apparently a fairly common problem with cadillac's with the northstar engine. i believe this to be a design flaw in the engine, and because the cost is so high, makes it very difficult for owners to have the repairs done, and hence are driving cars that are both environmentally unsound and potentially unsafe due to the leaking oil.
