Any 4G TL owners got issue with this problem? I noticed whenever I fill mine up or when it's cold out, sometime I get a notification on my dash to tighten gas cap. I would pull over, check the gas cap, drive off and it still shows. Then other time it doesn't shows. I have went to the dealership to have it check out and they said its common due to the weather changing. Any owners with this problem?

 

I never had that issue, but that's one of the funniest dealer responses ever. I would make them fix it, bro.

 

you have a faulty gas cap, go get a new one and see if it does the same thing

 

I started getting that message aperiodically during my last year of ownership of my '10 ... normally after filling the tank (and by filling I mean topping off with out overflowing). Normally it would disappear within about 15-20 miles of continued driving. I was told by a dealer that it 'could' be caused by something other than condensation finding its way into the overflow outlet. First time happened after filling when outdoor temps were around freezing, but don't believe the other times were totally weather temp related.

 

I had the same issue with the warning message, there's a TSB which was a software update. Once update was applied, the message never came back.
