My 2018 Challenger SXT with 94K miles, didn’t start earlier.
I was stranded in the middle of no where for two hours. Until it magically decided to work again like there was no problem. Except, I have traction light on now and can’t turn it off.

Has there been any recent drivability issues with the trans?

If not, I’d be more inclined to think this was an issue with the wiring harness plug that connects the engine control module to the transmission control module. That or actual damaged wires in that section of harness somewhere.

No matter what it is, you will likely have to take it to a pro to get an accurate diagnosis. We can guess over the internet all day, but without some way to actually diagnose the symptoms and retrieve data from the car’s computer, guessing is as close as we’re going to get.

I have a garage but how know where this car’s been sitting before…
I’ll take it to dealer tomorrow, hope my engine starts in the morning…. 😅

So I tried to start my automatic 8-speed 2015 Scat Pack earlier today and I received the message "Service Transmission. Continue in D(rive). Do not shut engine off. Shifting may not be possible.". The odd thing was, the engine was off (although the electrical was still working) and I was in...
