Just went in my garage to put something into my Denali. After I closed the door all of the interior lights faded to darkness except. the 2wd/4wd control pod in front of the armrest. I waited for a few minutes and the switches remained lit. I assume that the 10 minute timer will eventually turn the light off. I'm wondering if this is an issue or if it is normal. Can I please get some feedback from those with the new generation as to whether this is normal. I realize that feedback will be slow in coming until at least dark unless your vehicle is in a darker garage. Thank you in advance.
