Entered Limp Mode on the Highway

This exact same thing happened to me yesterday, luckily I was not on the highway, but I was driving on a main street and several cars behind me started honking. I had the truck towed to dealer and the dealer says there's no lights now and when they test drove it for 30 miles there was no issue. I also had another issue where when braking the whole truck shakes. I asked the dealer to drive again and check for the braking issue as well.

I am having a similair issue with multiple system warnings- took it to my dealership and they claim they cant reproduce the pre collision assist fault- which happened multiple times for me and anytime i stepped on the gas hard at all- but they did of course find $1200 worth of work to do- replacing the throttle body , which was one of the other faults- im afraid after pating all this money the original problem wont even be solved

Have you checked to see if your truck has any recalls? This sounds very much like symptoms from trucks that got a bad software updates last year from a recall. Then those trucks got a recall on the recall software update.

I just got two recalls fixed a couple weeks ago and i believ they did a software update, now its back at the dealer with multiple fault warnings happening- they say its unrelated but i dont believe it- the truck was running perfectly before i took it there
