Took the units out, cleaned them(really was not to dirty). Reinstalled and still “temporarily unavailable “. Read online to disconnect ground cable on battery for 10 minutes, nope still does not work. Anyone have any thoughts?

I have the same issue, brought to the dealer, they said it’s an issue with dirt/ salt buildup. Was told it is a know problem with no fix other than to take unit apart and clean. Since it’s listed as a “maintenance “ item dealer is not responsible for the repair. The vehicle (2026 2500hd) it is washed 2/3 per week. I have taken it to a self service wash and sprayed all around units, still not working. Was told that I need to take them off and clean them. Going back on previous posts, some as long as 6 years you would think that GM would have found a fix, possibly enclosed the area. So even after this gets resolved, the system is useless because as much as I enjoyed it on my Ford, I won’t trust it on my GMC.
