    Have you experienced the headlights in auto mode doesn't turn itself off after the car emerges from shaded places?

    Here's what I've noticed:

    1. Start the car in the garage, headlights are on, drive it out of the garage, headlights immediately turns off.
    2. 5 minutes later, I stopped under an overpass waiting to get on the freeway, headlights turned on.
    3. Headlights remained on for the next 20 minutes while on the freeway.

    It was after 8:15am, so there are plenty of sunlight and therefore the headlights should have been off.

    Sometimes I also notice the headlights turns on at 4:30pm, this is in AZ where currently sunset is around 6:30pm.

    Sounds like a sensor problem. My headlights turn off from my garage before I get the the end of my driveway everytime.

    Had this issue this afternoon driving into NYC...came across the lower deck of the George Washington Bridge and the lights came on as they should. Got onto the West Side Highway headed south in blazing sunshine and the lights never went back off.

    Based on its behavior, the sensor seems to be recessed slightly into a cavity by design, so that when the sun is low, the headlights stay on even though there's enough ambient light outside to see.

    This is a good design, as it keeps your headlights on to make your car more visible when an oncoming driver may have the sun in their eyes.

    Not saying that's what's happening in your case--just thought I'd mention it.
