my fuel pump circuit sensor went out which caused other parts to malfunction and need replace took over two weeks to repair and then i was told it was not an engine part and would not be covered under my warranty and the staff at the corporate office are the worst people to get a hold off and return your calls just to tell you i am sorry but we have decided that this condition is not classified as a engine part and so it will not be covered under your warranty and you can pick up your vehicle to have it repaired somewhere else if you like but you will have to pay the dealer 190 dollars for the diagnostic test they performed to determine the problem and hang up i will never ever buy another car from Chevy
