I recently hydroplaned and within 20 minutes my truck was thrown into limp mode. Service Shifter was the first wanting, then Service Transmission, service electronic throttle, service electronic braking. Now when these lights come on, I can park and shut my truck off, wait 30 minutes and start it up and drive fine.
These lights are not on constantly. They don’t come on every time I drive it either.
What Boostn said. Happened to my 2017 driving in slushy snow conditions. Intermittent messages and sometimes wouldn't start. Found corroded connection in transmission harness.

I haven't experienced that specific issue but several times while underneath my truck changing oil I noted that the wiring harness connector had been pulled from it's attachment point on the frame and was dangling in the wind. I pulled the connector apart, applied electrical connector cleaner, liquid spray, and once dried applied Dielectric Silicone Grease to the connector and reinstalled the connector and buttressed with a zip tie.
I would also search for Pending Codes with my scanner not just existing DTC's, and clear them as well.
