I have a 2020 gmc sierra 1500 elevation. At around 10,000 miles my service 4wd light came on. Next, the vehicle was stuck in 4-low and I had to have it towed to the dealership. The service tech said it just needed an update and was good to go. 2 days later the same light comes back on and off to the dealership I go. Anyone else have this issue and get it resolved?
