I have taken the truck to the dealer several times, and they have not been able to diagnose the check engine light problem. The engine light tends to disappear a day or so later. The local dealer can't diagnose or replicate the issue.
Update from May 23, 2026: I took the vehicle to the dealer again, and finally the issue was detected. The Gear Shift Module, for which there was a TSB, needed to be replace.
