In owners' own words
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. Engine
With no warnings from the vehicle, I noticed a loud knocking sound while driving home. I was able to make it home and have the vehicle towed to the dealer where it was found to be in engine failure due to failure of engine bearing. I had to have a complete engine replacement. My car only had 65k miles and was purchased brand new and had all regular maintenance completed at the local chevy dealership. Engine
Car burns excessive amounts of oil and have to add regular quarts of oil between the mandatory oil change. Considered vehicle could malfunction and cause and accident or catch fire. Dealer said they have recalls for other chevy suvs and trucks with same issue but not my particular make and model. This issue with chevy's burning oil warrants an investigation since chevy is not addressing the issue. Engine
