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.

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 recommendation. My understanding is that cadillac recognized this problem, and made a correction to these north star engines in the year 2000. This is obviously a cadillac blunder that is proven costly, but the cost is only being absorbed by the customer. I am all for being accountable, but having the choices of putting a 3rd engine in the car or junking would be deemed as extreme. Why is cadillac not recalling this particular year cars engine? I am sure that any research that you conduct will show an abundance of this problem. What protection does the consumer have in this regards?

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.

Attention: ms. Denise [email protected] after reviewing the information service bulletin sent to me I am under more convinced that this engine is defective. I have had engine cooling also high oil consumption every since 57.000 miles,I mention it to the service advisor and no one ever told about these bulletins no one mention that their was a problem with engine or tell me about the , fwd rtv sealant procedure with current oil distribution plate or the rusted heater pipes that go through the engine block that carries the coolant. Also leaks in the car causing fumes which are toxic. I must have 20- 1 gallon anti- freeze bottles in my garage. I carry at least 6 quarts motor oil with me, the over 75,000 mile oil. I use more oil and anti- freeze than gas.2006 consumer action handbook states and I quote" sometimes a manufacturer makes a design or production mistake on a motor vehicle. If dealers report a number of complaint about a certain part or vehicle, the manufacturer may allow dealers to repair the problem at no cost to you even if the warranty has expired. A service bulletin notifies the dealer of the problem and how to solve it. Because these free repairs are not publicized, they are called "secret warranties" the federal safety agency maintains a database of service bulletins filed by manufacturers. I also have all the maintenance records for my 1998 cadillac and was never imformed of these problems or I would have had them repaired when the car was under warranty. I have doctor's appointments I can't keep because I don't have transportation. The dealer told me I have blown head gaskets which comes from overheating due to the cooling leak and oil leaks.the heater pipes have rusted pouring out engine coolant. Which does not produce heat at this time. I need all the help I can get, I"m on a fixed income and money is scarce. Why don't they run copper pipes they don't rust. It's for the heating system. Please help.
