Had a few codes pop up at 99,987 miles. Any help is greatly appreciated for a fix. Codes b124d, u0258, u0252, u0208, u0200, u0199, u0256, b1448, b1182, u0164, p193e, p05b0, and p05ae. Basically started with blind spot fault and cross traffic fault then went in in to running boards not deploying, ac losing power, radio volume not adjustable, door locks not operable from inside buttons, and whatever else. I feel like it is all connected since no troubles prior to this. Also if truck sits for a while when I crank it runs just fine for about 10 minutes, then all goes faulty. Seems like a short somewhere but don’t know where to look first. Figured I would turn to the experts here.

Possible suggestions while you wait for people way smarter than me.
Low battery charge
Poor connection of battery cable to battery
Poor/corroded ground connection(s).
When the "U" codes clear, things may go back to normal. Those are communication problems, no communication and lots of haywire stuff. Start with cleaning your connections to the battery and getting the battery on a charge (if if not possible -get the battery load tested at a parts store).
Is something amiss with MS1-CAN comm network? Because it started with BLIS system, check condition of rear tail lights and the associated BLIS modules and connectors.

Working to check this out the best I know how. Seriously thinking it is all related since everything happened at the same time/day without any notice or condition to make it occur. My brother mentioned a gateway module from another forum post and is looking into that. The rear tail (bottom) light is out.

As mentioned before, it is a common problem to get water into the connectors at the SODL or SODR (BLIS modules) in the rear taillamps. Those modules communicate over the MS-CAN bus as do almost of everything else you have "U" codes for. Start with the taillamp that is not working.
The Gateway (GWM) Module controls all four communication buses and is what communicates with the OBD port. If the problem was there, you likely would either see more codes or no codes at all, depending on the failure mode.
Codes for days
