My new Silverado was stuck in 4WD. The dealer found a Chevrolet "Field Action" for the vehicle that indicated the transfer case shift control module required reprogramming. The "Service 4WD" message appeared on the driver info screen.

 

Some of the vibration issues being reported could be that the truck is stuck in 4WD - that causes steering wheel vibration at highway speeds. In my case, the control knob was in 2W HI and there was NO indicator light on the knob. The service 4WD did not come on initially.

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

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 m

I drove today approx. 200 miles with Auto setting due to black ice this am. I came home tonight fine and parked in my driveway for a few hours. I tried to backup in to my turn around and noticed immediately. that it was in 4wd, yet the dial stated 2wd. I tried the dial with no effect. I also saw a service 4WD error on the display.

 

Have others had this issue? Does anyone have more info on the field report referenced above?

Thanks.

Yes. Cold temp is screwing up the tccm. Take it to your dealer to get reset, and wait for permanent fix from gm.

 

Dealer told me to put the truck in 2wd before shutting off, only codes in auto/4wd on startup. So far so good.

Mine is stuck in 4 wheel drive. Reprogramming didn't help, it lasted a couple of hours! After the reprogram it flagged the alarm again while I was driving with it in 4hi. Contacted GM last week but they have not gotten back to me! Trying to back in of dry pavement is brutal and I'm just causing more damage! Come on GM.....fix my truck!!

Reprogramming on mine lasted 8 days before the service 4wd light came on and it locked in 4wd again..... Back to the Dealer again.

Take it in. Alot of problems with shutting the vehicle off in below freezing temp in 4wd or auto 4wd, starting back up and being stuck in 4wd with the shift knob display not working. The only thing the dealer can do is clear the codes and tell you to shut the vehicle off in 2wd until they come up with a fix. Per bulletin No. PIP5250

Another couple months and we won't need a fix till next December! I'll never remember to put that back in 2 wheel drive after every trip! But I still loves my truck!

So did GM not test these trucks in below freezing temperatures? I'm really curious as to how this could possibly happen.

I was told the same thing but i never remember to do it and it hasn't done again, been about a month but its also -10c not -35c when it happened. I guess i have to move to Florida to drive a new GM

Wow! Can't handle the cold? What a joke. Mine just started acting up since having the transfer case recall done. I'll have to try the 2wd shutoff option and see if that helps.

GM has never been the leader in vehicle electronics technology. I recall when these 14's first came out reading about numerous starter issues and power steering issues due to freezing temps. Sad to hear now there are 4WD issues as well due to the electronics.

 

One can assume GM proving grounds are somewhere in Arizona only where they're road tested for a week then sent into mass production.

They do have one in the Yuma, AZ area, but also one in Milford, MI

You can assume that if it makes you feel better some how, but you'd be wrong.

Same thing they told me.

Shutting down with 2wd selected didn't do anything for me. Still stuck in 4. I got a service appointment for Friday so we'll see how that goes.

      MPG at 600 miles

      By Byrds8 · Posted

      100% agree, there are a lot of variables. I definitely do not drive I’ve like a grandpa but also don’t drive like I stole it. Truck is currently in the shop so I’ll have to get weight later. The price for driving it doesn’t bother me. My precious was a 6.2l so the cost between the two is a wash.

      summer road trips in the 2026 2500HD

      By c4racer2 · Posted

      that is pretty awesome MPG there!  I think so far one observation is these trucks do way better on MPG under 65mph vs 70+ and they really suffer at 75+   I noticed on the stretches into NE on 76 and 80 which is posted 75MPH and I was doing 82 I was getting more like 13.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By newdude · Posted

      No ETA is available for that engine at the moment in the GM system.   I would start at the dealer.  Try and talk to the parts manager or service manager and see if they can start a CX Connect case and get an ETA from GM on when engines may be available.  If they just check Parts Workbench and say "no eta", they aren't trying hard enough.  They need to do a CX Connect and chat with DPAC to find the ETA.

      MPG at 600 miles

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.
