I've had the car about a month and can't seem to fill the tank properly without it stopping not being full.

What is that about!!! I know how to put gas in a car!

 

here is the tsb for this take it to the dealer for replacment. have them order the tank protector also as some of them have been breaking. it takes about 2 hours. so if you bring it in first thing you should get it back in the afternoon
