That code is also tied to other parts of the emission system. When mine threw that code, I also swapped out 2 OEM caps without success.
Finally took it to the dealer for a smoke test and found that there were several leaks in the system (old hoses) and a purge valve.

I had that error one weekend about 2 yrs ago in my 2012. In my case, a re-seating of the larger hose that goes to the Evap canister instantly fixed the warning message. Nothing I did with the gas cap had an affect. Really, I just grabbed that hose and rotated, pushed, pulled, then the light went out. I'll try to find a picture of the hose. Under the hood. By firewall on drivers side.

Around here, it's like $100 for the test.
