So factory is denying my powertrain warranty on the basis that i went 8000 miles a few times Based on my service records. I read that others have gone as high as 8500 or more before an oil change. I always went of the oil life system. My cel came on, took it to dealer who said oil pump failed due to sludge and now I need new engine. I'm at a loss at what to do, feel like Chevy is not standing behind their product and looking for a way out of fixing my '14 cruze with nonturbo engine.
