I have had this problem for a long time. Its disappointing to see that no one else has been able to get it fixed either.

I had the problem of the Gas Cap issue, I replaced the gas cap with 3 different models and at the same time happened to start having another issue where my Malibu was powering off while driving. The power failure was an issue because they could not run diagnostics because the computer was resetting. They pretty much told me I was making it up. I started keeping a journal that stated what order the lights and warnings went of at and mph I was driving and if my lights and radio were on and how long before I could restart and get back on the road (I started only driving in the right lane so I could coast off the road safely). I drove back and forth three times to the dealership, all three they told me to come and get my car, nothing was wrong with it. I finally lost it and told them to keep it until it was fixed and after three weeks, they called me and told me that PMC Module was bad and they it was covered under my 100,000 mile warranty along with the Gas cap issue which was a leak in my fuel line and was an emissions issue. I have not had a power failure. What a head ache. My check engine light has been on ever since and this happened two years ago. Not sure why its on but I have not had any issues since other than cosmetic (door panel ungluing and DVD player stopped working). I purchased this car new in 2005, I will not purchase another GM product.
The light of the gas cap on went a turn the car on
