I filed my NHTSA report on the fuel gauge almost two years ago (see my August 2010 post above). This week I got an official recall notice - it will be fixed for free by Infinity - "repair the fuel gauge circuit board". I'm not sure this is the problem since posts here reference the trunk sending unit, float arm, and gauge cluster - but I will demand it be fixed if the it is something besides the circuit board.
I called Roswell Infinity today and they know about the recall and gave me an appointment tomorrow.
The recall says "If you have previously paid to have it repaired, you may be eligible for reimbursement". If you have a problem, call Infinity @ 800-662-6200, NHTSA hotline @ 888-327-4236, or go to

Like others posting here - losing about a quart of oil every 2,000 miles. Changed the spark plugs, put a quart of Lucas oil treatment in with an oil change, and am replacing the valve cover gasket while checking valve clearance. We'll see if those things work.
Also, the trunk closing struts no longer pop the trunk, but I hope to find after market ones a lot cheaper than what Infinity will charge.
