My 2010 Buick Lucerne daytime running lights are always on. On previous Buicks they went out when you shift into park. Is this normal?

Yes. The manual says the light should go out when the transmission is in park.

Dealer says it's normal and that the Owner's Manual is a misprint. I have owned 5 Buicks with DRL and this is not how any of the other ones operated. LJM.
P.S. What is BCM?
