2005 Cadillac DeVille DHS 4dr Sedan (4.6L 8cyl 4A)
The car will stop running and everything shuts down even the OnStar. I get no help from the dealer or GM. The car has been towed in 5 times. Also when the trunk is opened you can smell battery acid. I am very unhappy with this car and will never buy another GM product.
