I just got the vehicle and had no problems out of it. I put just $20 worth of gas in and and it registered 3/4 of a tank. When I woke up to go to work it showed that I had over a full tank of gas, until I started to drive it then it dropped back down to the original amount. Then it did the same thing the very next day.. I'm not sure if I should be concerned about it.. Just wanted to tell some one about it..
