Autopilot error APP_W397

[CTSomi]

Has anyone seen this error before. I googled and found nothing. I've lost all autopilot/FSD. This issue popped up day #2 of ownership.

I've also seen an article saying HW4 computers have been failing. I have a bad feeling this is related.

Was there any resolution to this? I just had the same error message, and lost all autopilot / FSD. Truck doesn't recognize any vehicles, stoplights, people on the digitizer, but has the lines and won't lane keep anymore or show blind spot monitoring. SC has ordered me a new autopilot computer ahead of my service in 3 days, but concerning nonetheless! Did they replace the autopilot computer for you and not had any issues since, or what happened?

Yes, they replaced the HW4 computer. I think it was the first time my service center had seen that error/issue because they had quite a bit of trouble getting the new computer to mate to the truck. Good news is I've been trouble free since then and we're at 11 months now.

Also great that they've already ordered the computer ahead of your visit. With mine, they had to diagnose the issue, then wait a week for the part to arrive. They might turn you around in a day.
