Picked up my MX in March, and almost immediately suspected that the interior rearview mirror was loose. It would hold its position for smaller drivers, but at the angle that would allow me, a taller person to see, it would kind of wobble slowly and shift upwards. Last month, the SC told me that this was a defect and will change it when the new parts arrive. He did mention that quite a few MX's have the same problem, but I haven't seen any threads about this issue. Anyone have my problem?
