quarterwave Posted October 30, 2017 Report Share Posted October 30, 2017 I hate these little nagging things with cars now days.... After 3.5 years and 41,000 miles, the Check Fuel Cap message is coming on and annoying my easily annoyed wife. I checked the cap, re-seated it, ran the car, message came up. I scanned it, no codes. Besides the obvious, bad cap or seal, has there been any trend on these things having some other failure? I buy from a very good and reputable dealer, but every time I ask if they have heard of something happening on others, they always say no. Chrysler probably makes them say no. LOL> Thanks.

2late4u Posted October 31, 2017 Report Share Posted October 31, 2017 could be fixed as easy as just replacing the cap or something more complicated who knows.my son has a 5 yr old gmc truck that has twice had a warning light about his emission control problem both times has been a cheap fix but it happens to all the manufacture of autos. nature of the beast, of course in the old days you wouldn't get no warnings that something wasn't right and it would go until it caused a real problem or breakdown at a unfortunate time. just wait till we get driverless cars won't that be fun,,,,,, i dont think so... jkeaton 1 Quote Link to comment Share on other sites More sharing options...
bfurth Posted October 31, 2017 Report Share Posted October 31, 2017 It's either a bad fuel cap, or a bad fill port (most likely). Next time you fill up, check underneath the rear driver side to see if you find any signs of a leak in the filler tube. If not, replace the gas cap (only a few dollars) - that will almost certainly fix the issue. If that doesn't fix it, then you'll need to do a few more drastic things, including a more thorough inspection of the filler tube and/or dropping the fuel tank and inspecting for obvious signs of damage. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
jkeaton Posted October 31, 2017 Report Share Posted October 31, 2017 Be sure to use OEM (from dealer) gas cap only. Aftermarket won't seal good. 2late4u and lmccat 2 Quote Link to comment Share on other sites More sharing options...
