While fueling the car at the gas station, the pump shuts off and a second or two later, about a half a gallon of gas sprays out. This problem keeps getting worse. I've tried to fill it up on the lowest setting and I've tried pulling the nozzle out of the tank some so the (harmful) vapors can escape. It is happening about 90% of the time and this is not a safe thing to have gas coming flying back out and getting over the ground, myself and others around me. This is a real safety hazard. I have found there is a lot of issues with the 2005 models and now the 2006's are having the same problem. Apparently the problem is still not fixed. This problem is way out of control. I will be posting my youtube video along with the hundreds of others to show how unsafe this issue is and how it is being handled by the manufacturer and safety organizations involved. Hopefully this issue gets resolved before a real injury is realized.
