The vehicle dropped a cylinder head valve and was fixed under original factory warranty in 2012. It was fixed by the dealer using factory parts. It was on the freeway and the motor lost almost all power. I had to get towed. It happened again in 2016 after 20,000 miles and religious oil changes. This car was maintained meticulously. They cylinders were found to be at fault of destroying an exhaust valve both times. Additionally, the number 8 cylinder was found to be consuming oil, which destroyed my catalytic converter. This is all with a vehicle which had under 40,000 miles (within powertrain mileage warranty, but expired duration warranty)

At 3,900 miles my new car was down 1quart of oil. Upon questioning I found this was common problem with 2001 corvettes. At 15000 miles gm replace pistons but said that it is acceptable by gm stardards for the corvette to burn a quart of oil every 900 miles. However they won't give me information in writing only to my lawger which I don't feel needed yet. I also had a friend who has same year corvette as mine and he two is burning oil. It is a know problem even in gm web sites for it mechanics. Please help I'm tired of checking oil and reporting consumption to dealership I didn't purchase a 50,000 car for this.

Oil consumption is above normal for a new engine. I have experienced the consumption of more that one quart per 1000 miles. Dealer initially stated that this was normal for a new engine and would improve after a good break-in period. Problem remains. Research has shown that there is an acknowledged problem with excessive oil consumption. Catalytic converter and exhaust pipes show significant black oily residue. Concerned about potential fire from catalytic converter. Also concerned about environmental effects. Chevrolet needs to take positive action to resolve issue.
