I haven't approached the dealer but I did notice the extra effort needed to switch the mirror from day to night mode. I put it down to the plastic being really cold at the time. The other thing I noticed was the length of the 'throw' needed to make the change. My Kia Rondo wasn't nearly as stiff and it was an easy switch, pushing forward with my thumb and pulling back with my index finger. Didn't need to take my eyes of the road to make the change, either.
