Good evening all,
I just experienced the weirdest issue and wanted to bounce it off y’all. I just got in my ‘18 F-150 diesel w/ 19k miles and got a solid back dash with only my turn signals on solid. I sat there for 20 minutes opening and closing doors and pressing the break (which was rock hard) and the ignition to try and reset something. After 20 minutes the truck decided to randomly start when I pressed the ignition but through a check winging light and a **** load of errors. I ran the ODBII and received 20 errors. I have since driven it to the dealer and dropped it off with 18 codes still present. Has anyone seen this? See attached
Conditions:
The truck had been sitting for about 4 hrs at about a 5-10 degree slope with nose up at about 88 degrees Fahrenheit. No issues prior.

Very good documentation, thanks. Hope they can get your truck up and running soon. I think it may be something as simple as one of the electric connectors being loose or not making contact. Hope for an easy repair!

THIS IS NOT A JOKE: Ford told me since the truck was in direct sun that it got to hot...WTF I am in Seattle and it was only like 85. If you are in Texas or Arizona I recommend taking you truck I. As it might explode🤣. This is the most horse **** response I have ever received on a truck malfunction.

Ford stated that the cause was some part of my dynamic cruise control system over heated while sitting in the sun. When I got the truck back they had it sitting in the bay all day. I guess they didn’t want to test the new part. Here goes nothing, I will be going to eastern Washington tomorrow. 🤣
