Consumer Description

My vehicle went from completely fine to having a loud knocking noise while I was driving 65 mph down the 4 lane highway. My vehicle lost power and slowed down. I was 50 miles from a dealership. They had to replace my entire engine and crankshaft. It cost over $12,000.00. This exact issue has been recalled by GM, but websites say my vehicle is not covered. The dealership had my vehicle for a month doing repairs.
