So far I only put around 500 miles on the car and loved every minute. I've been reading about some of the common problems and am trying to determine if mine has any of them. So far the drivers mirror appears to be solid. Unfortunately it does have to go to the dealer tomorrow because the Bluetooth stopped working. The options on the screen are greyed out and can not even be accessed. Hopefully it's an easy fix and the whole unit doesn't have to be replaced. I did read of a few that were successful in getting it working again by unhooking the battery for a few minutes but the Mazda service department didn't want me to do this, they wanted the CX9 brought in. Aside from the current issue the CX9 has been awesome.
