I set my headlight to auto. It works well in most scenarios except when going from bright to dark surrounding. Every time when I drive the car from bright outdoor to my condominium's underground garage,it takes 10 to 15 seconds for the headlight to automatically turn on. There are 2 light sensors for that in the car and there is no obstruction to the sensors. I took it to the dealer and they changed the sensitivity from medium to maximum, but the problem remains exactly the same. The delay time is still the same. It appears to be a software problem.

The same delay problem also happens to windshield wiper activated auto headlights. It appears to be a software design mistake.
