The gas gauge is irradict. I can have just filled it up and moments latter the needle pegs out at zero. Then after a short ride it pops back up.

What does your dealer say it might be? I am guessing you talked to them first before asking here.

I did not talk to the dealer. I prefer to hear from other owners. Input from owners is sometimes more benificial.

Take it in, no need for speculation or advice, it's a warranty issue.

I myself, am waiting for a new set of headlights, as the dealer somehow overlooked the fact that a very important screw was missing and my headlights were hanging out of the socket.
