OK.... so I think it is fixed this time. New updated program required to get this running is #PIT6504 dated Apr 1 , 2026. Appears the applications cover numerous Chevy and GMC vehicles with fwd col, AEB, and LKA options. Hopefully this helps someone out in the future with these issues.

I am really glad I found this post and this site... We have a 2022 1500 refresh LTZ that has these problems: - forward collision avoidance warning light - lane keep assist unavailable - adaptive cruise control unavailable The truck was bought as a new leftover in 2023, so it was still under the 3/36 B to B when it went in for these problems earlier this year. It has been at the dealer on and off now for about 110 days now. These are some of the things they have done that I can read on the service tickets. - replace/add ground straps (4) - check all battery cables and vlts - replace serial data gateway module - replace front view camera - numerous reprogramming - a few calibrations (apparently ending with 'learned') Last week when I had it back the truck had those 3 warnings every time we used it except for 3 times. On three separate occasions the truck started and ran perfectly with no (zero) warning messages or warning lights lit - everything worked perfectly. Over that same time period the truck did not work on every other 'key' cycle which I would estimate at 60+ cycles. On those estimated 57 cycles it had the same 3 problems each and every time. It is back at the dealer now - can anyone help at all with what the true problem might be? Or possibly what can be ruled out leaving a lower number of possibilities? Thank you very much for any help you may be able to supply....
