Re: Gas gauge issues
There's another thread on here, titled, I think, Gas Gauge Issues Thread, in which this issue is discussed by those who have experienced it. IIRC, mostly 2006 and 2007 had the issue, but one or two 2010 said too.
Drop the tank and free up the stuck float lever (or cut a big hole in the floor under the rear seat and free up the stuck lever that way).
Sorry that this happened to you, hope you can find that other thread, and that it is easy to fix.
