      A reader is having a strange issue where the sunroof on his 2024 Sierra opens automatically.

      “When driving in daylight, then going under an overpass or thru a tunnel, the headlights come on. When the headlights come on and only when going from day to dark the sunroof opens.”

      Is anyone else having this issue?
