2018 Equinox AWD System messages

[rick0415]

When I start the car a message pops up saying "Service All Wheel Drive System Dismiss" when I click on Dismiss a message comes up at the bottom of the Android Auto screen "SuperCruise and Fuel Level 85%".

The AWD indicator lighjt on the center console does not light up. If I push the button the Service All Wheel message comes up again.

To troubleshoot further, you'd have to start with a full code scan. How many miles on your 2018? Do you live in the rust belt? The only electronics associated with the AWD system are back by the rear differential. There is an AWD control module back there and a wiring harness that could suffer from the effects of corrosion.

Here's a pic I borrowed online. The pointy tube end points towards the front of the vehicle, but you can see the components and the control module on top w/ the wiring.
