"Service 4WD" - Master Thread
No problem goes this long without a fix. The engineers would be looking for work. If a problem persists for a length of time such as this it is because they are trying to find an inexpensive solution. That said - I had my truck fixed 3 weeks ago with new software. The service manager said...- Coltsneckbob

"Service 4WD" - Master Thread
My truck was taken in for service of the problem 2 weeks ago today. They told me they had a s/w update to fix it. The dash now displays a "4WD mode change" message when I switch. So far so good. I can use 2WD, Auto and 4WD with no problems. The 4WD does not make any unusual noise either...- Coltsneckbob

GM just called me. They just gave me $1,000 for my troubles!
Yes, GMC gave me several perks. First my Yukon Denali was delivered 9 weeks beyond the original expected date. This was due to inability to get a train to ship it and then some fire hazard they had to correct while it was still at factory. They gave me a free loaner to use for 6 weeks. I...- Coltsneckbob

Mine was fixed yesterday. The service guy told me it was a known problem and (duh) and was under recall. He said it was a s/w fix. Obviously something was done with s/w. When I switch to 2W, auto or either 4W the dash displays a new message (well at least I never saw it before). It...- Coltsneckbob

Well, I called Roadside Assistance. They told me not to drive the vehicle and scheduled a pick-up with a flat bed for tomorrow morning.- Coltsneckbob

Thanks for the information. I have had 4WD trucks going back to the early 80's (mostly Fords) and I was always advised never engage 4W on a dry road because you might wind up the trans/axel. When this occurred yesterday (1/17/15) I called On-Star right away. They acted like this was some...- Coltsneckbob

New Here I just experienced the problem yesterday where my transfer case locked into 4WD. I have a question though. Will it harm the car/trans to drive on dry roads with this condition? I need to get to the dealership for repair and it is 10 miles away?- Coltsneckbob
