New Yukon XL with 7,938 miles. Wife just left neighborhood to take kids to school and the car shut down and won’t restart. Saying there is an emissions issue, so now waiting to have this towed to the dealership it’s crazy that it won’t even let me restart and limp along to move it out of the street.

Update: tow truck showed up. You can’t put the vehicle into neutral without starting the engine and he didn’t have the wheel rollers that would be needed. I decided to try disconnecting the battery, which actually worked. I started the car fine and drove it to the dealer for them to look at. Seems like a possible electronics problem? Unfortunately disconnecting the battery clears the codes they said, which is crazy that they don’t get saved in GMC system. I got an alert from the GMC app about emissions issues, so why couldn’t that save the issue?

All DTCs are stored. It might not be an active DTC anymore, but even a $10 Bluetooth code reader from Amazon can tell you history codes. More advanced scan tools can show you FFD (freeze frame data) that can give a tech a glimpse at various sensor readings before the fault code occurred.
If the dealer says they can’t see the fault code then I would go to a different dealer.

Yea, that dealer either didn't want to deal with it and told you a story or they had their heads up their collective asses.

Just out of curiosity - what’s your DEF level?

IF DEF was the issue, there would have been warnings on the DIC that fluid level was getting low, etcetera.
My guess is an electrical issue, these things just don't go "bam" and shut down unless something isn't communicating/connecting.

Def was 75% level, so it wasn’t that. Definitely seems like an electrical issue. When I had it in for an oil change a month or two ago, they did a software update that was required. After that, when you start the car and drive, the radio audio wouldn’t play unless you changed the channel. I brought it in to have them check things and they said they needed to replace the whole thing based on the diagnostic result.
So maybe the radio issue has some relevance to what was going on?

Maybe your Dealer needs an update.

Do you have it back? If so, is it behaving?

More of GM's famous quality control. Sad.
I had something similar on a corvette. One harness connector wasn’t seated well. I had to self diagnose since the dealer couldn’t get consistent trouble codes to diagnose it. Seating it fixed it. However, later the connected wiring harness started going bad. Seems like at some point during assembly the harness must’ve got yanked out of place, and was rubbing through the wires.

Can you call OnStar and get codes from them still?
Sad that we all got screwed by not being able to move our vehicle without it running! My 2022 battery went bad and was blocking my other vehicle which left me stranded. Why the hell would GM manufacture a vehicle that can’t be placed in neutral and moved a few feet, without it being running? Ridiculous.
The tow truck driver has to either drag it up without the rear wheels spinning or place the rear wheels on mini trailers to move.

@DocDoug i agree, it’s pretty stupid “design”.
Latest update: the other day my wife was driving and the audio stopped working. The blinkers had no audio and the radio didn’t either. Even after changing channels and from Sirius to CarPlay and back, it still didn’t work.
After she turned the car off for a bit and then restarted, everything was working again.
