This happens to my 18 every once in a while when i hit the memory seat number. Dealer never gave me a real answer other than they couldn't replicate it.
I also notice if I tap the same memory seat number a few seconds after everything readjusts, the mirror moves a little... tap it again it readjusts again, and again.
This is only the drivers side mirror.
Yeah, only the driver side too. During this cold winter, i remotely start a lot. when I tough the handle to open the door, the mirror start clicking. this happens more frequently then before.
I dont know what to do if the service man will not replicate it. I request all reports everytime i went to the dealer.
