It is a very common problem. I think all GTO's have the old trick gas cap issue . It will have you cussing everytime you have to fill up . I bought a new one when mine messed up and right after I paid over $20 for it I learned that Pontiac was replacing them for free. You might still get a free replacement I dont know.

Ohh and to get it off I believe you just have to push the cap down gently while you twist kind of like a bottle of asprin.

ya it was like the clicking mechanism in the gas cap broke. it wouldnt do anything but spin freely. i got frustrated cause i was really needing gas and ended up busting the gas cap with a flathead screw driver and then using a pliers i was able to just twist it off, and i bought a new one from autozone for $10.

The cap is warranted for 10 years, take the car to a former Pontiac dealer they will look the VIN up and replace that. They may also reimburse you for the cap you purchased.

Your issue is the first I heard, mostly they don't ratchet on and can be lifted off. I am on my 4th cap. The newer ones have an "improved" design but same problem. Even the G8's have issues with these.

That is good to know, mine went bad last yr, and I just went in and purchased a new one, Next time I'm in I will mention it to them and see if they will reimburse me or just give me a spare one. My problem was the same, it would not tighten on, and just lift off.

I've had this problem, but usually it's with putting the gas cap back on the filler neck. Annoying I know... it's funny to watch people's reactions as you cuss for 2 minutes trying to put it back on after you're done filling up.

So you're serious, if I go to a defunct Pontiac dealership, they'll kick me a new one for free? There "used to be a Pontiac" dealership about 4 miles from my house.

same with mine...just had to lay it on there...took it to the dealership a couple days later and it was working again...they told me they couldn't replace what wasn't broken...I showed them the paperwork from the TSB (or whatever it was, copied it a couple years ago) and they looked at me like I had three heads...

...I may just buy a locking Stant cap out of pocket rather than get stuck...

I even had a CEL come on; "small leak" or something like that was the code. If the cap doesn't seal, you'll get the light. Got a new one from Autozone for $12. works but just doesn't have a peg for the lanyard to attach. I'm just glad that light stays off now.

Yes go to your former Pontiac Dealer. Original owners of this car should have received the following letter, print it out and take it to them. This was addressed to me personally I omitted my name on it.

***unfortunately the reimbursement time line expired but its worth a shot. However if you still have the defective one, you will get a new one.
A loud DUH will come from a dealer "out of the loop."

Although this is addressed to a 2005 GTO (my year) all years are affected. Notice in the letter it states NOT TO APPLY A DOWNWARD FORCE when tightening.

That's not necessarily true after the initial code if this happens repeatedly. Once the computer is reset you may not get the notice again. I got it once (the first time) in the 4 times I had mine replaced. I noticed the other times when the cap was just sitting atop the neck and when it would ratchet but not secure. Every time I fill now I gently try and lift the cap up to make sure its working.
