    I kept getting the check engine light and tighten gas cap. Paid dealership (almost $200 including labor) for a new gas cap. Now almost a year later getting same check engine light and tighten gas cap. This time they're saying I need to replace evap vent solenoid for $130. It seems like a lot of the issues with this car are the same. GM should step up and solve them.

    Same issue, worn gas cap allowing air in the tank and check engine light. Bought a new cap and fixed the issue. 50,000 miles later still no re-occurrence.
