Has anyone else gotten one of these on the DIC I had it pop up twice a few weeks ago. I haven't noticed any issues with my AWD since. The TSB tells the dealerships to ignore it but not why it happens.

I haven't seen this message, but it is on the TSB list.

This just happened to me. Its in the shop but they say they have no idea why as there is no code popping up for it.

Sounds like a software issue which has been common problem. Ask the dealership if they can download the latest update.

They said they would do that while they have it
You should be ok. I haven't heard of any "real" problems with the AWD system, just software glitches which can also cause other messages to pop up like "service power steering system" or "service ESC", etc.

We got a "service chassis" message months ago. Dealer found no code or the like for it. We have not seen the message since.

Yeah there are several glitched messages out there. I haven't seen one for while now and none since the last software update. I would only worry about a warning message if it's accompanied by a check engine light (CEL) or if something seems obviously wrong.

Other than a leaky coolant line to some cooler or the like on the TB ours has done well, closing at 9k miles.

Hi, same here, I just got this warning sign "Service All Wheel Drive". Trailblazer 2021.
Driving cold water. Near freezing water.

we had that warning like 3k miles ago. No issues with the system ever. Appears to be one of the few ghost in the machine messages the TB throws up.
