Blindspot monitor not available message

Firing up an old thread. Anyone have a Bling Spot Monitor not available after just dust? Seems like all the above reasons are mud and snow. Did about 20 miles of dusty dirt roads over the weekends. No issues on a 3 hour highway drive after that, but on the way home from the office 2 days later I get the BSM not available alert going off.

 

Check the wiring/connectors?

 

Looks like this is probably the issue. Noticed the driver's side of my rear bumper is separated a bit more that the passenger side. I think my underside of my bumper got pulled when going over a ditch on an old logging road I'm on about once a month. I don't see anything loose wires, but assuming I'll need to take the bumper off to get a good look. Odd it go out right after that though, and didn't stop working until a couple of days later when on the interstate.

 

Who knows, might’ve been enough to stretch a wire and it worked it’s way out. just seems like the easier route to look for trouble before diving into computer stuff.

 

I’m getting this this morning after not having done anything but city driving. 55k miles on my 2022 so out of warranty
