Yes, I have the same issue when going under a Bridge or overpass. They also take a long time in the morning to go off once the sun is up.Does anyone notice the hair trigger on the sensor that turns headlights on & dims dash lights automatically? Mine triggers even when going under an underpass or even from the shade of passing a tree on a sunny day. Only takes about 2 seconds for the dash lights to dim, but considerably longer for them to come back on. This cycling is annoying. Had a Lexus w/autodim feature & it worked like a champ.
