Buicks tend to have problems with grounds, especially the ones for the BCM, my last Buicks seats would just quit working then would start back working, took me a long time to find the problem due to the intermittent operation, it was a ground wire under the passenger seat, and yes I did have to remove the seat and carpet on that side, after that I have found similar grounding issues and BCM connector problems. Do not rely on the dealer to find the problem cause they won’t go any further than checking for codes, and as it won’t leave a code that’s when they stop.

Yes, yes & yes....erratic behavior in the instrument cluster. Where is the body control module located?
Your vehicle has on the left side of the dash, after you get the lower panel off you should be able to see it.
