hey guys, having a little problem. i went out to get gas last night and the gas attendant couldnt get my gas cap back on. the fuel door closes. the cap will not screw on. hung out there for about an hour trying to get it on. also had other people try, nothing. im not sure if the guy broke something when he unscrewed the cap. seems like a part might be missing, but couldnt find anything on the ground. anyone else have this problem? is it safe to drive the car with the cap not screwed on? i cant get the car to the dealership till monday. im gonna go crazy if i cant drive my car till then.
