Have had cap replaced at least three times since we purchased auto. Started around 15,000. Dealership closed and any recalls, we are told need to go to a GM dealer or not covered even if other shops were certified through GM
My light comes on and I make sure the cap is secure and it is --I wonder why the light keeps coming on
A Toy Story Sticker solved this one for me. I stuck it right over the indicator light!! THe darn thing comes on EVERY time that I am almost empty. As soon as I fill up, it may go off, it may not. Sometimes I only have to turn the car off, go outside and screw the cap on again. It's not a very smart car.
Check engine light came on went and had it diagnose. The code indicated leak in the emission or gas cap. Went and bought a gas cap from dealer, check engine light never went off.Took it to have it check out after buying gas cap. The shop claim they couldn't find any thing wrong. The shop reset the system, check engine light went off. Two weeks later it came back on. Had it dianose again. Finding that it a leak in the emission reserved tank. Which is leaking gas from one of the hose in side the tank. Wow what danger.
The light came on signalling a Gas Cap issue. I bought a new one at the dealership where I bought the car new, and we still have the problem.
Every year code p0455 comes out large leak on evaporation system change the cap one time work but now a message come out in the dash board saying loose cap
light comes on ck gas cap have bought three new gas caps from buick dealership and yet still have the same problem
Light just pop on checked gas cap don't are any problem with gas cap
removed gas cap and reinstalled. After a tank of gas the light went off. It has occurred twice with same result.
Check engine light comes on frequently due to gas cap :(
Gas cap no longer latches causing the check engine light to illuminate.
