Engine burns a quart of oil every 1500 miles. Dealer says this is within tolerances. Burned no oil for the first 15000 miles, then a quart after 3000, then a quart after 2000, now a quart every 1500H.

I have had an excessive number of problems with this vehicle. The latest problem is the radiator hose blew off the the water pump causing the engine to overheat and seize. I was already in the process of documenting an oil consumption problem. The extended factory warranty company (gmpp) has changed their mind 4 times about why it's not covered under warranty. I paid $23,000 for this car and now I have to rebuild the motor too! if anyone else has experienced similar problems with gmpp, I would like you to contact me by E-mail at evalyn.nunnery@metagroup.com my suggestion is to never buy an extended warranty because it won't do you any good if you ever have a major claim.
