Check engine light on
2 weeks after getting the vehicle, got the same problem. Turned out the cap was good, just needed to be turned a couple of times. Now I crack the max out of the cap and it hasn't happened since.
In normal operation the engine light came on. Went to AutoZone and they ran a diagnostic check and told me the gas cap was bad. I went to the dealer who did not hurt me to badly, replaced the gas cap which took all of two (2) minutes and drove the car. The dealer told me that the light would go off after 15 cycles (starting, driving, and cutting the car off). Seems like it took forever for the light to go off but it finally did. The car just turned 100k.
