Assistance Please... ERR Codes, Beeps, Lights (Video + Codes)
While it happens...
So I was driving back to work this evening from dinner when I attempted to raise the drivers window... it would not go up.
Then this happened: The gauges you see in the video went down to "0" and back up again.
Various display messages on the DIC came up: "Check Tire Pressure" "Service Vehicle Soon" "Service Active Handling" "Reduced Engine Power" "Shocks Inoperative" "Service Ride Control" "Service Traction System" "Service Tire Monitoring System" "Check Tire Pressure" and one you don't see in the Video "Max Speed 80 MPH"
I apologize for the shakey video and radio playing in the background (AND still driving) but I just grabbed my phone ASAP and took a brief video as it happened. Trying to be as detailed as possible. I will post in the Tech section as well. Thanks in advance!
The codes I pulled from the DIC: (Some repeat but I have never checked the codes before so there were quite a few)
10-PCM: 1 CODE
P 1626 H
28-TCS: 1 CODE
U 1301 H

Start by reading this thread. It seems to apply well to your symptoms:

The consistent U1255 (Serial Data Line malfunction) really points to the symptoms from the link above.
However, if the info from that link doesn't resolve the issue, there are some interesting codes there that could help also.
Have you recently been having problems with your battery or perhaps replaced it or disconnected it? Many of the codes for the RDCM and LDCM are typical of battery related issues. If you recently replaced the battery they would show up. But a weak or bad battery or loose or corroded battery connections including the one at the starter can also cause them. So I would also check out your battery.......

I haven't replaced or disconnected the battery in quite some time. (a few months I would say) I will also check my battery connections and have it tested.
The starter was replaced about 2,500 miles ago because I was having the infamous no start issue (Which Bill assisted me with) so I will check those connections as well.

Something is corrupting the serial data line.. Either a wet/ corroded BCM OR a wet/corroded/damaged seat connector or door connector with damaged bent/deformed female pins.
Find the serial data connector to the LEFT of the BCM and pop the top of the one with four wires and see if the issue resolves it self. that will tell you if its the seat, LDCM or RDCM
