Gas Cap Warning Light On on Nissan Altima

The gas cap warning light may illuminate. The can be caused by a loose or defective gas cap or a small leak in the evaporative system. A small leak can be very difficult to diagnose, often times a smoke machine can be used to try and isolate a leak.

Loose fuel cap light comes on about twice a month. Usually after I have driven for about 1/4 tank after filling with gas. I loosen then re-tighten the cap and it takes quite a while for the light to go out. Right now it has been on for 2 days and will not go out even after tightening the cap twice. Very unsettling when driving in rush hour traffic.
Gas cap waring light comes on abot 100 miles after putting gas in the car. This then turns on the check engine light. Been to the dealer each time, one answer the gas cap was loose and it will reset in about a week, the second time the cap has to be put in an exact way to prevent the problem. I do know how to put a gas cap on and feel there may more to this problem.
Gas cap light came on today. We purchased a beautiful 2011 slightly used Nissan Altima purchased last Friday. The car is a dream to drive, very comfortable, love the key fob/no shifting, but argh...this light shocked me today! I sure hope this will not be a continuing saga. Oh bother!!! Went to dealer today, and they seemed unshocked by it...told me to bring back if happens again...sure hope not in vapor system, too. sure hope does not happen again or more like above poster. :(
