I searched for this topic, but all were old. This afternoon I ran into a
heavy rain and stopped at a gas station to fill up. When I started the AV and put it in drive, the "Service 4 WD" message appeared in the message center. None of the 2 or 4 WD buttons would light up. I shut the truck off and restarted, but the same results. I then drove away and it drove OK. I finally pressed the OnStar button and the guy could not find this message in his list of problems. He ran a diagnostic and found nothing. He offered to call the dealer to make an appointment, but I decided to do that myself. After I got home and parked in the garage, I let it sit for a minute or two and re-started and no more message. Earlier threads seemed to indicate Chevy may be aware of this, but I could not find any messages that imply the problem is fixable. Has anyone else had this fixed to their satisfaction??
