"check gas cap" warning keeps coming on. After getting gas I retighten the cap several times. The warning light stays out for couple of miles before coming on again.....and again. Mean while the engine warning light is always on.
anytime i fill it up the fuel ,it wont start right away,
Gas cap light coming on, checked and tightened the cap and now the engine picture light is on...I see I am not the only one with the issue. Does anyone report any stalling or other running issues, Now I am afraid to drive the van which has been wonderful up to now. It runs fine for me with the exception of having to pump the gas occasionally after it has been started a few times during the day.

light came on said check gas cap i did it was tight now check engine light on, wont start after you put gas in it dies at random points, ran computer scan said air leak in gas line
If the the gas cap is not screwed back-on VERY tightly, the CHECK ENGINE light comes on & the gas guage goes crazy. Just turn it SEVERAL times when closing & that seems to do it just fine! If it does go haywire the computer takes about 24 hours to reset.

The van was purchased new and at 18,000 miles the engine light started coming on and stays on. I changed the gas cap, but light still stayed on. My husband had this vehicle as a company van. He told the dealership over and over that light stays on while it was under a fleet or lease plan, but they never corrected it. I have tried to talk to dealership, but they said they can't help me because it has too many miles. It is kind of strange that 161,000 miles of the 172,000 they serviced it, but they never took care of the problem. The dealership has records of everything even 7 complaints of engine light staying on, but like I said they never corrected it.

Whenever i fill the tank with gas my check engine light comes on for about a day then goes off. I haven't had it fixed. Just a weird little quirk. Also the indicator on the gas tank goes to empty right after I fill up then slowly goes up to full by the next day.
My engine light is on at all times - when plugged into a diagnostic machine it says to check my gas cap. I did and nothing is wrong with it. The light stays on ALL the time now. Whenever i fill the tank with gas my check engine light comes on for about a day then goes off. It actually goes off after about 30 miles driven. I haven't had it fixed. Just a weird little quirk. Also the indicator on the gas tank goes to empty right after I fill up and stays on until about 30 miles driven then slowly goes up to full. I also have ding ding dinging on both of the sliding doors. They will not stay shut unless forced or closed manually. I learned the hard way you cannot ignore. Left over night it ran down the battery. If you disconnect the battery it will reset the dinging will stop (until you open the door again!) Also the heater in the drivers seat has been fixed 3 times only to quickly go out again. within the first 4 years!!! This vehicle should not have been put out on the market!!!!!!!

We had the vehicle hooked up to a code scanner. It wasn't passing the evap test. Thr code was low evap pressure leak or something. I replaced the gas cap with a new gm one. Still had the issue. Turns out the pressure sensor on top of the gas tank needed replacing. Replaced it myself. Problem fixed.

Everytime I fill up with gas low fuel comes on and then the check engine light comes on. I drive it to work and back. Take the cap off and ususally the next time i start it the check engine light goes off.

I've had this problem many times. Just check the cap and wait for the code to clear.
