I have replaced the gas cap 5 times on my 2007 Sky. Check engine light comes on I go to the dealer and they charge about $78. After the 4th time they wanted to see me take the cap off and on. I am not doing it wrong. Mechanic said the rough ride of this car can juggle it loose. But loos the deal? I see I not alone. Still a pain. You never know for sure what it may be as every time it has been the gas cap.
When I drove my Sky Red line with the A/C on, when I shut off the engine, the fan is still running (sounded like the engine running) for at least 5 minutes before it shut off. Please advise! Thanks,

Same issue. Just got a new cap, but warning light did not go off immediately when replaced.
