After 350,000 miles, the center control buttons end up wearing out (well, the internal coating of the button). Thanks to this forum, members have tracked down the correct replacement components to "rebuild" them.
I would encourage anyone that has button issues to spend the $5 and tackle the job. Very simple, only need a small pick and a screwdriver.
