My problems occurred when the temperature was below zero. There is a new software fix for this problem now supposedly. I've had my vehicle back for two weeks and the problem has not repeated itself but I have only tested it down to about zero degrees. I won't know for sure whether my truck is really fixed until next winter.

Mine stuck in a boat launch one time and there happened to be a mechanic waiting to launch and he crawled under the truck and banged on the cable with a hammer to get it to release. This is usually a problem though with an older vehicle where there is rust, dirt and corrosion blocking the cable's release. This seems to be too new a vehicle for that problem so it is some type of adjustment problems I am thinking. You may have to get under there and bang on that cable to get it released so you can get it into the dealer pronto!

They can't be trying too hard if the 2014 models had the problem and now the 2015's still have the same problem. Keep documenting all of the problems you have and file through the lemon law. If they get enough of us filing maybe they will wake up! I'm afraid to use the four wheel drive mode now for fear of it locking while I'm going to work. Had a hard time getting out of my icy driveway this morning. This is ridiculous!

My truck is only two weeks old with 1000 miles on it. I live in Minnesotain a rural area so getting in and out of my driveway can be difficult so generally keep my truck in the Auto four wheel drive mode at all times. Two days ago after sitting outside in below zero weather I remote started the truck for warm-up. When I went to start out and put the truck into drive I noticed the Service Four Wheel Drive alert come up on the screen. I thought it was part of the self test the vehicle goes through so I click the disregard button. Not sure what happened but did not notice if the truck was in high four wheel drive or not but the selector remained on the auto setting. When I got done with work nine hours later when I went to drive away I noticed the truck was definitely in four wheel drive mode, but this time in the low mode. I could not get it to come out of low four wheel drive. Called the dealer service department and they had me try different setting and shut the vehicle off and restart but nothing worked. I have fifty miles home from work so my dealer suggested going to the GM dealer in the town where I work and not to drive the vehicle. The dealer there said they were too busy to look at the truck but told me they have had four or five 2014 1500 Silverado's with the same problem and there was a service bulletin out on the problem, but get this GM doesn't have a fix for it. Evidently the Automatic Transfer Case on Some of these vehicles have a condition in which an electric signal short or software glitch may cause the active transfer case to switch without operator input. The transfer case mode selection knob would still indicate the last selected drive mode, and the driver will not have any feedback that the transfer case has shifted. I looked at the service bulletin and it was dated December 22, 2014! So now I am pissed off as I have to get home somehow. I call my dealer again and they say they will pick up the truck in the evening with a flatbed tow truck! Remember this truck only has 1000 miles! So I get a hold of my wife, and I'm sure you can understand her mood when I tell her she has to drive the 50 miles to pick me up and the 50 miles to take me home again!! The next day, yesterday, the local dealer calls to tell me they have the truck out of four wheel drive and in the 2 wheel high mode. So I ask what the fix is and they too tell me there is no fix! Can you believe this? The service bulletin suggests keeping the truck in a heated garage (they don't furnish those where I work!!), and only shift into four wheel drive or auto four wheel when the vehicle is started. The best part is that when you shut the vehicle off make sure the drive selector is always turned to 2 wheel drive only. I don't know about you, but I know I going to forget about that again at some point and be stranded with the thing in four wheel drive low again!!! In the mean time the service department tells me GM is working on a fix. People, this is a $53,000 sticker price vehicle! I mean they must have known about this problem for over a year because not only are the 2014 models affected but also some 2015's! And this was Truck of the Year?!!!!!!!! What should my next move be on this vehicle as this is totally unacceptable and not even sure when if ever they will have a fix and I can't be without four wheel drive for my commute and getting out of my yard!!!

I have the same problem and just got done posting a long narrative about my ordeal under another topic heading. The long story short is I was told about the service bulletin and the same BS about have to keep it in 2 wheel drive high before shutting it off, the low temperature problem, etc. The bottom line is there is no fix and it is also showing up on 2015 models! Come on GM this was supposed to be truck of the year! Looks like maybe there needs to be a class action suit started here!
