Can anyone shed some info on this. It's the 3rd or 4th time I start the truck and get the message on the cluster " Rear Axle System Off". I play with the drive and mode controls and it only erases when I hit the "check" button on the steering wheel. All seems to be normal. But it's concerning. Any info???

Still under warranty? It sounds like the system is turning off the locking differential.

On other gm cars with elsd this can be caused by misfire, old batery, voltage issues, alternator, ground issues, etc.

100% only has 7000 miles bought in December 2023 abd also gas 120 mile whatever year extended.
But thanks for the info. That could be it.
