I've got an '09 that I've had at the track several times, including last Friday. As usual, I had to fill up part way through the day, but with unusual results. The gas pump cut off automatically, and when I removed the nozzle from the car I had a HUGE backwash of gasoline down the side of the car and down the pavement. I would estimate 1-2 gallons. It slowed to a trickle after about five minutes, at which point I put the cap on. It was a hot day (90 degrees- hot for Calgary) and the tank had gotten down to about 1/8 full. I'm wondering if the fuel tank got hot enough to vaporize some of the gas when it entered the tank, thus expanding and causing the backwash. All I know is the car was hot as hell from lapping,and I could imagine it going up in a ball of flames- especially when I got in and hit the ignition button. Has anybody else seen or heard of this?.
