I have a 2007 chevy Hhr with 175,000 miles on it. Last summer I noticed a gas smell when I would shut the car off. I thought I over filled the tank and the excess went into the charcoal canister. Recently early Jan. 2020 the check engine light came on. So, I did on line research and people saying the gas cap was bad. I took it off and it looked fine. Check engine light was still on. So, I called the dealer to make an appt. They did a computer scan and code p0442 came up ( small evap. Leak) and they said my fuel lines had a lot of rust and could be leaking behind the wrap that separates the exhaust from the fuel line. I've seen on line there are many people having trouble not only with the Hhr but also but other chevy vehicles. Is there any way customers can get reimbursed to get this issue resolved. Took the car in 01/23/2020.
