    165 miles and I got a service 4WD message

    I posted this in your other thread: I have been reading this thread as a supplement to the other thread on this subject. But in this thread some have said that this problem may be user error. This is not the case, it is a computer control error in the system. Auto 4wd is a system that...

    9,865 miles 4Wd services just come up

    I have been reading this thread as a supplement to the other thread on this subject. But in this thread some have said that this problem may be user error. This is not the case, it is a computer control error in the system. Auto 4wd is a system that is designed to sense road conditions and...

    165 miles and I got a service 4WD message

    My Service 4wd message came up after the recall work was done. They did the relearn on it and so far so good. I cycled it again yesterday with no message.

    165 miles and I got a service 4WD message

    Yours is the Transfer Case Control Module gone bad, not unexpected for your year and mileage. Its a pretty easy fix on yours, but not necessarily cheap. ---------- Post added at 07:47 AM ---------- Previous post was at 07:46 AM ---------- GM really needs to figure this out before it snowballs...

    Why do some of you want to make us early buyers feel bad about our purchase. And I think most of us agree that the 8 will be better. But, my 6 speed will be fine till I replace it in a couple of years when it is mated with the 5.3 and has a little time in production. I have never bought the...

    Exactly. Oh and don't forget, GM sucks because they cant fill the enormous amount of orders for POS 6 speed equipped vehicles that nobody likes because the theoretical 8 speed is awesomer than all the others. Note: Spelling error was intentional and I am not a professional driver and I am...

    Gotta love forums. " Its not the car, its the way "you" drive", awesome. The V6 seemed under powered which forced it to hesitate and hunt for a down shift in slow traffic. Caveat, I am not a professional driver. Thus my observation is both unqualified and meaningless to this thread. I want to...

    Was there this much bashing when GM changed transmissions in the previous model. And the 8 speed is no surprise, I knew it was coming in March when I ordered mine and didn't give it a second thought. Anyway, washed mine this weekend, took the family out, outdated 6 speed and all. Have fun...

    165 miles and I got a service 4WD message

    After reading this I had the wife cycle ours and it worked fine with no light. My dealer did a simple relearn on the Tcase and it seems to be holding. I truly hope they get it worked out for you.

    Buyers be Aware

    This is dealer problem. Mine tells us to bring it in early and gives us a loaner while its being done. Not all dealers are created equal. I custom ordered my SLT XL and had it in 3 weeks, why, because the inventory manager modified an existing dealer order instead of starting from scratch. A...

    It is. :) If you cant buy it, build it (or have it built). I did, and its awesome. GM did not change the body bolt jig for the new model. From what I understand, You can bolt the new body to the 2007-14 3/4 Burb frame, then swap in the Diesel and voila, NNNBS 3/4 ton towing monster. Mine...

    So no 8 speed till mid 2015 for the 5.3. So none of Chevy line up is getting it till then. Wow The Chevy LTZ guys are getting screwed for sure. I cant figure buying the top of the line Chevy product and not getting the 8 speed, but buying the GMC top of the line product you do. I have the SLT...

    Converting a 15 Denali XL into a real truck

    GM dropped the 3/4 ton Suburban, that is what I was referring to. the 2500HD is the truck. I believe GM made a huge mistake dropping the 3/4 ton Suburban/Yukon XL, but unfortunately they don't build vehicles just for me.

    200 miles since the relearn and no light. Fingers Crossed ---------- Post added at 10:58 AM ---------- Previous post was at 10:55 AM ---------- Last Chance, do you run yours in Auto or 2wd? Also is everyone here running the 2 speed 4wd or Single speed. Mine is 2 speed with 2wd, Auto, 4hi, N...

    Converting a 15 Denali XL into a real truck

    A small lift is in order. And you will need to take a saw to the front air dam. That thing is stupid low. I think it will do what you want, but an 07-14 3/4 ton would be better. The 3/4 ton gives you leaf springs in the rear for better hitch weight. Plus 6.0 V8 and better ground clearance...

    Yet another problem: Oil Leak 2015 YD

    Have you had the oil changed. If you have, they may not have seated the drain plug. Happens every time I get mine changed, so now I just have them torq it before I leave. My 89 Grand Waggoneer doesn't leak oil and they are the worlds worst.

    165 miles and I got a service 4WD message

    Well the dealer did a relearn on my transfer case. I have cycled thru it multiple times during a 20 mile drive with no issues. I am not confident at all, but we will see.

    165 miles and I got a service 4WD message

    Darn sensor. I wonder if they can sense frustration. Hopefully that will fix it. Sure sounds better than driving it around in 4wd to loosen things up.

    165 miles and I got a service 4WD message

    I think operationally it depends in what mode the error occurred. Mine seems to be hung up in auto 4wd. I would be real worried if it were hung up in 4hi. It would be undrivable in 4 low or neutral. See if your dealer can tell you what mode it is hung up in, that would determine weather you...

    165 miles and I got a service 4WD message

    Add me to the list of people with the "Service 4WD" message. We have driven our from day 1 in 2hi. Today we hit a heavy downpour so I flipped it to Auto 4WD. Stopped for dinner, got back in and flipped it back to 2wd and the indicator never illuminated. My dealer has been great on...

    I am gonna drive the early 15 for a couple of years, then upgrade to a 16 after the 8 speed is proven. Simple.
