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.
