Software update - If it ain't broke, don't fix it

Perhaps it wouldn’t have been so bad if he had recognized the error and advised me of it instead of driving off telling me that everything was OK. He had to have realized the problem when he drove the truck back into the garage.

You seemed to describe your issue as a total electronic failure which makes it sound as if it were undriveable? The tech did drive the truck back in to your garage to park it, correct? Again, plausible that the truck was acting perfectly fine but something didn’t save well when the truck went into sleep mode.
I don’t know this guy, but I do know how incredibly difficult these modern vehicles can be.

And regarding the progress on the repair, I’d like to shed light if I may.

If a control unit is locked up it most likely needs to be replaced. Warranty usually won’t pay for a CU replacement unless Technical has been contacted and they’ve given the go ahead.

The guys on the manufacturer side of the Tech Line are also traveling techs that go around to their assigned dealers where they have to work a whole day trying to exorcise all manner of demons, AND THEN reply to the requests from their other dealers from their hotel or home if they drive back. I know this to be true. These dudes are unsung heroes, and there is a gigantic talent gap - listen to Mike Rowe for explanation on that front.

Control units are rarely kept in stock, so it would have been ordered. Ever since the Covid shutdown, parts availability has been a major issue.

What I’m trying to say is, man, your, our, techs are really trying. This software stuff is all invisible magic and we aren’t software engineers.

Also entirely possible that the dude is a hack and murdered your truck. I think the dealer wouldn’t send that kinda guy on the road though.
