Of all the stupid reasons to have my car in the shop! When I drove my car home from the dealer, I noticed the tank was only 3/4 full. Thought that was a bit cheap on their part at the time. So when I went to fill it up the first time, the fuel gauge only went to 3/4! Took it in, and they said the vapor canister in the tank was not venting, and therefore not letting the tank fill all the way. Got it replaced, and it still only "fills" to 3/4! So they're lookin' at it again. Any ideas on what might be going on?
