2019 Ram 1500 longhorn acting crazy

[Alberto]

Hi, I have been searching for a fix of a recent strange behavior that started in my pickup truck (2019 ram 1500). One month ago driving at about 40mph all indicator lights went on, wipers, turn signals too, also I lost power steering. I pulled over and shut the engine off. Then started the truck again, now only the check engine light was on, 5 minutes past and the issue started again.
I immediately went to the dealership and they checked the battery and wires, said that everything was OK. Yesterday it started all over again, but now it dangerously shifted to park.

Here's a video when it stared.

I noticed several posts detailing a similar issue, have you found a fix yet?

FYI: couldn't attached the video, bur I uploaded to the cloud instead.

What codes were stored? With all those lights on, I would suspect a communication error code. A bunch of them, actually. Or a bunch of failed to initialize, something like that. Erratic voltage can cause those. Is the battery original? Forget that the dealership tested it. Plenty of people here have had batteries go berserk randomly but test fine, and once the battery is replaced, it is cured.

Previously had an issue where it would not come out of 1st gear.

The remark of it "dangerously shifting to park" could be the RF hub acting up.
Check for the leaky window running down the back seat and shorting the hub.

My 2019 ram 1500 big horn did this same thing today. Cluster went crazy, wipers came on, lost power steering. I was cruising at 75mph. Went straight to orilleys to get the codes checked and just bunch of communication errors or lost connection with pretty much everything. Went by the dealer in uptown dfw and they were 0 help. Did you ever find a solution?
