Chevrolet Corvette Z06 Years to Avoid

The 2006 Z06 as the first year of the C6 generation accumulated the most complaints, with the LS7 engine developing valve guide wear causing dropped valves in some cases. This potentially catastrophic failure requires expensive preventive measures or engine rebuilds. The differential on early 2006-2008 models showed premature wear, producing whining and requiring replacement. Clutch chattering affected many manual transmission cars, especially in hot weather. The exposed headlight motors collected debris and failed. The 2015 C7 Z06 had different issues including overheating during track use and supercharger bearing concerns.
