My 2000 Oldsmobile Intrigue with the 3.5L motor overheated. I had the vehicle towed to my dealer and after a week was advised the motor had to be removed and the heads pulled. Apparently due to the reaction between the steel head bolts and the aluminum motor, the threads corroded and gave way allowing the head gaskets to leak. Since the car had 113,000 miles on it, it was past warranty though I feel GM should have put some type of coating on the bolts to keep this corrosion from occuring. Cost in this case approached $4,000.

Car dies at highway speeds. Been to dealer 4 times. The dealer changed the crankshaft position sensor twice. The fuel pump and battery once. When car dies it will not start untill it cools then it will run normally untill it happens again. Dealer has said General Motors has had a bad batch of crank sensors. When the car shuts down at speed it is very dangerous.once it happened on a bridge, im afraid of a bad accident if they cannot resolve the problem.

Intermittently, vehicle shutters when coming to a stop, turning corners, and starting up. Its getting worse. Dealer was notified, and unable to determine the cause. Consumer states there is a service bulletin on file regarding this problem, however GM has not determined how to correct the problem.
