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.
The problem with the check gas cap message and will not pass inspection in the state of Texas. No solution yet to be found.
The light of the gas cap on went a turn the car on
i have changed the gascap several times and the ones that are supposed to fit dont.

Check gas cap / engine light have been on for approximately 2 to 3 weeks. Ordered an OEM replacement but did not correct the problem. Looks like I might have a evap leak as others have mentioned.

Engine light came on , computer said to it was the gas cap. It was'nt the gas cap but rather the fuel filler neck which is apparently made of a hard plastic that has split in its stress point. I'm convinced that this is a common problem in GM malibu maxx hatchbach vehicles and could be a potientially deadly and dangerious defect. Their is no recall that i have received yet and the apparent OE reconfirgured replacement , that i'm sure won't be of the same orginal material , is a outragious $400 dollars from the gm parts department. I managed to find it for $350 after an exhausted internet search , but will have to save up to purchase it and in the meantime i hope my patch work holds.I'm not going to hold my breath for GM to recall it , does people got to die before that happens.The parts man at the GM dealership gave me no warning of danger but he commented that he thought the price for the oe filler neck was outragious when he told me in his words "he said he could'nt see why it was so expensive to replace and let me just walk away. How concerned is GM any way after all of the recent recalls you would think their people would be trained to look for these problems. I think it all about the money , they don't wan't to spend , their not concerned about human lives. Hope i survive till the problem's fixed.

sporatically gives the check gas cap message for the past year, then clears after I take it off and readjust the cap. Finally this month it popped a code P0455. Will be replacing the gas cap but from all I have read I am not overly confident that it will correct the problem.

This is the second time I have had this issue in the last 4 yrs. I have replaced the gas cap three times. I was finally told that it was NOT the gas cap but was in fact the fuel evaporator canister near the fill tube that was the issue (about $150 to have fixed by mechanic). I replaced that and problem was resolved for about 2 years. I took my car to have recall work done at dealership and they broke the sensor tube near the throttle body. I replaced that for around $40 (easy fix). I still have the check engine light on and the check gas cap message. I was told that a leak anywhere along the vapor return line can cause this issue. I live in NC and any check engine light will not allow vehicle to pass inspection in my county. I don't have the money to have it traced right now so car is sitting in driveway until I get money to have car checked out. I hope this helps.

I drive a 2005 chevy malibu maxx ls and i have had every problem in the book. The simplest problem that i thought could be fixed isnt fixed. First speaking of the gas cap problem. The dashboard said to check the aftermarket one i replaced in 2012. I went to get another after market one in 2014 when the check gas cap light came on in the dash that locked and put it on. Then suddenly check engine light comes on!. Later i find my evap has a hole in it and then i just took off the new gas cap because it was obviously making things worse. If i knew chevy was a GM car i would have NEVER bought it. Im only toyota

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.
