Lots of "Lost Communication" faults

Hey.
2023 Tundra, 17,000 miles. Was on the freeway, every single dash light came on, a message like "LOW BRAKING POWER, PULL OVER" popped up. I seemed to have full brake power and appeared to operate normally.
Towed in, dealer pulled/cleared a bunch of communication fault codes. They opened a TAS issue, did some basic troubleshooting, but in the end found nothing and gave me the truck back, asked me to monitor it.
60 miles later I get the same light display on the dash, including message to pull over.

I looked through TSBs, none seemed to apply, but I donno. Does anyone have experiences like this? What'd your dealer do?
I would attach the service report/invoice but I am having trouble attaching a file. Codes were:
P0500, U110687, U0129, U015187, U012987, P050031, U114F87, U014087, U010087, U010187, U012900, U011487, U012587, U012687.
Seems like every module that could have a comms loss, had one.

 

I have no idea, but it’s on Toyota to fix it.

 

Oh, for sure its Toyotas to fix under Warranty.
Its also on me to deal with this huge hassle and complain to the dealership and next up Toyota USA. Both times it broke down I had the whole family with me. Miserable time.

I have found sometimes a dealer needs a little hand holding to prod along. With my previous Chevy I had to print out a TSB and wave it around to get them to do it. I donno.

 

A bunch of unrelated faults. Battery?
Most dealers are pretty good about replacing it before they start ripping into the SW and HW modules.
Good luck.
