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.

we had lost our gas cap and ended up spending $65 to get it diagnosed cause the engine light was on only to find out it was because the gas cap was gone
