Engine shut off

[Suekon105]

2023 Yukon Xl Denali with 6.1L engine just shut off driving on interstate. Won’t start but power (battery) works everything else.
My GMC app tells me everything is fine!

Waiting on a tow truck.

Unbelievable! 38K miles. First trouble of any kind we’ve had and the app didn’t diagnose any issues. I don’t understand, and I see in this forum others have experienced the same issues and problems.

Well….its because you are missing .1 L’s.

Sorry, I know that doesn’t help. I’m assuming you have plenty of gas?

Here is a thread that has some of same sounding problem.

2022 Yukon Denali XL completely shut off while driving

Hi Guys, I never been posted on any forum for car until now. I have yukon denali XL 2022 with all updated services. I was driving on highway way on 9/15/24 at 7pm and the car engine is shut off completely while driving on highway. I try to use the SOS button & OnStar button and they keep saying...

But bottom line dealer will have to diagnose. Good news I believe your vehicle is under warranty.

Must be a Monday or Friday build!
Bring it back to dealership immediately and demand a refund.
They built your motor .1l less than the spec!

Assuming the engine cranks over normally, then my guess is the (FPCM) fuel pump control module.

See this thread here - https://www.tahoeyukonforum.com/threads/spare-fpcm-fuel-pump-control-module-wise-idea.152090/

If engine does not crank over as expected, then maybe you lost the engine?

Hope the problem is the FPCM and the dealer has one in stock, a 15 minute repair and your back on the road.

Update the thread once you know what the issue is and hopefully you have the vehicle repaired and are back behind the wheel.
