I just saw this topic - thank goodness because i thought I was either hallucinating or the car is haunted. I drive through rural areas and i find the ambient lighting quite distracting so i turn them off and leave them off. Except, maybe twice a month they'll come on (often midway through a drive!) of their own accord. I can't relate this to any physical switches, temperature, remote start, etc.). Since I am the only driver, only use one set of keys, and this happens infrequently (once every 20 trips on average) - I can't nail down the cause. Twice in that time (I've had the car 8 months & 20k miles) both outside mirrors point straight down. Once this occurred when I was backing up and used the zoom feature on the backup camera but couldn't get it to happen again. If i had to guess it's either a firmware issue or perhaps an intermittent short somewhere. Cheers! /Gerry
