There was a recall at one time for the transmission linkage about it popping off, I am now having it pop off I have no clue how long it been this way seeing as it goes to the dealership and they never said anything but it had been that way for a while you can just lift it off. Head lights go out almost every 6 months on the dot! I have been caught twice with no low beams.
