AWD vs 4WD

I have not kept up a lot with GM trucks the last few years. The keeping up I have done mostly revolves around the Gen V motor.

 

Anyway, I am little surprised to find out that none of the full size rigs offer AWD anymore. Is this correct?

 

For the last 12 years or more, AWD was available on the Denali, Escalade and Silverado SS in the form or a viscous coupling or a open center differential.

 

As far I can tell, all trucks including Denali trim Yukon and Escalade now only offer a 2 speed driver selectable 4WD transfer case.

 

Are there any K2XX rigs that have AWD?

 

Any discussion on this? Buyer demand? I know there was some complaints about performance of the last generations open center differential and it's performance on snow.

 

Thanks!

For real? EPA testing is only done in 2WD I assume?

 

Surely there is more to it than that. These are not the economy leaders for GM... But they sure do make up a big chunk of volume production

It wouldn't surprise me if fuel economy came into play. They only test the trucks in whatever the default mode is. And every little bit helps when it comes to fleet fuel economy. My other guess is just consolidation of features. Having an AWD transfer case means additional parts.

I guess I will chalk it up to:

 

-Fuel Economy/GHG Emissions

-Consumers not demanding it

-Production simplification and cost reduction

 

I guess it just surprises me, when damn near every German crossover/SUV and many other downmarket vehicles have AWD standard or optional but promote it heavily.

 

I am not against it. They are trucks after all. But it at least seems like the Escalade or Denali might offer it to be competitive. They sell like hotcakes anyway, so GM will keep on keeping on.

In the end the auto 4WD setting is basically the same as AWD. Of course whether or not it's okay to run auto all the time is subject to a massive debate here. lol

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
