There is a gas cap warning on my dash but i dont understand why the gas cap is closed as it should. As anybody experienced this issue already ?

 

The seal on the gas cap could be bad.

I'll bet you have more than one code.

All the computer knows is that there is a "large" leak in the Evap system. If it happens to detect it fairly soon after a fill-up, it calls it "gascap" because it may be the most logical cause, since the gas cap has been off recently.

 

Took mine in for that too I have a '12 also

 

mine did this too, not sure why though. It went away and never came up again.

what was the verdict from the dealer?

 

Mines an 09 and its the first time it does that. Anyway its going i just ordered a 2012 crush !

 

To save yourself a lot of time and pain of going to Dealers or Mechanics, get yourself an On Board Diagnostic tool. If you are popping hot for a fault that you know damn well that you fixed, you can delete the code from you vic's computer and remove the check engine light. Ensure that the On Board Diagnostic works for your model. I have a P/N 92063.9001 that works on my '07 JK.

 

Or a tuner. My Superchips will diagnose and clear codes as well

 

I have had to replace mine before

 

Well it seems to have diseappeard magicaly thanks guys

 

Could be a bad hose on evap can. I had that in my KJ and ended up fabricating a hose for it. I was not going to spend $90 for a 8" hose. No freaking way.
