So my burb will randomly tell me to service the 4wd system. Usually when it does this the 4wd buttons stop working and I'm stuck in whatever was selected. I'd say 30% of the time the "auto 4wd" button will still work so I'm not stuck one way or the other lol.
A lot of the time a simple turning the truck off and on will fix the issue as well. Could it be the button panel going out or is it something else that's common?
