I noticed the last couple of fill ups, the pump clicks and when I get in the car, it is not completely on full, a smidgen below. Kinda like it reached into that extra 3 gals that is not used and then is only filling up to the 12.6 gals and is displaying not full. I thought I read there was a TSB about the fuel gauge? Is there? Or is it just how my car is sitting the gas station ? I filled up at a" "more level " station and it seemed to get "fuller"
