Also note.. the TSB I reference relays the problem as non-functioning Welcome Lighting, but the deal where the car just lights up all by itself... is the same related issue. Mine was doing it the night I took delivery from the dealer... we all wondered what it was doing... figured it was because it was outside the window and we had the Key Fob at the salesmans desk right there.
Come to find out... the vehicle needs to be locked for the approach lighting to activate and has to have been locked for like a few minutes with no interaction with the Key Fob before it will setup to trigger on next Key Fob recognition. (My vehicle was unlocked, mirrors deployed/unfolded when it was doing it). Ehhh hindsight....
