Whenever I attempt to fill up my car it always stops before being completely full, it stops about 1/8 of a tank short of being full. Then to completely fill up my car, I have to shake, rock the car, then pull the hose out rock the car more put a little gas in and do it all over. Sometimes it can take me over ten additional minutes to fill up my car. I have taken it to the dealer a few times for this, and they tell me to bring it back when almost empty and I do and they put gas in and say that they don't see anything wrong. I think they are thinking that I don't know what I'm talking about and they only put gas in and when I get my car back it still is not full, and of course it is closing time and it seems like they still don't understand what I'm saying the problem is.
