No start command! 2020 JT Overland with V6 at 127,000 miles. Two weeks ago had misfire cylinder 3 code. Changed plugs and coil packs and message cleared and no return. A week later ASS light came on. Got home late and didn’t drive it for a couple of days. changed Aux and main battery and all was good. Three days ago and It won’t start. All lLights are good but not even a click at the starter. It acts like the start btton has been pushed with my foot off the brake. On one attempt I did get a “START PROTECTION” message with a 60 second countdown followed by an indication that the passenger airbag was on and the Blind Spot Lights on the side mirrors flashed once! I Have checked battery connections, fuse array, fuses, remote start and key fob start. I manually put it in neutral to try a start and no luck there. I tried a new start relay and also confirmed the brake lights come on when pushing the brake pedal assuming that verifies the input from the brake pedal is good. It just acts Like the start command isn’t getting to the starter solenoid. At a loss on what to try next. Afraid I’m looking at a tow to my local shop!

You mentioned “ key fob start”. Is that where you push the start button with the with the tip of the keyfob?

Go back to the beginning. Check your battery install. Charge both batteries to full. Reset the IBS. Random troubleshooting only creates more issues. That's my opinion.

CAN connectors behind glove box?
I looked at the CAN bus connectors and everything looks ok. Don’t really have the equipment to verify inputs and outputs. And that is the Key Fob start method I was referring to.

It is the solder joints inside the connector block circuit board that crack and cause intermittent issues.

The below video discusses it with him opening it up and showing the issue at the end of the video.
