Replaced the gas cap at 5000 miles because it keep loosening between fill ups and the check engine light comes on. Now I am having the same problem at 12000 miles.
Have only 21600 miles on 2006 Corvette (2nd Car) and check engine light cam on. Took it to dealer and $125 to diagnose the problem- turned out to be the gas cap seal was causing the problem. Part replacement was $28 so for a mere $153 the problem was fixed - what a rip off.
Had Dealer replace gas cap, but doesnt seem too secure. I hope Chevy can come up with a more secure gas cap.
Gas cap loosens and check engine light illuminates. Replace at approximately 32000 miles, with GM gas cap. Problem started again at approximately 40000 miles.
