Yukon Stopped While Driving

[cjlewis]

2023 Yukon Denali Ultimate - Was driving home from work and it just stopped running. Had to coast to the side of the road. Aux power comes on; however it wont start, doesn't do anything and can't shift out of park. Being towed to the dealer. Anyone have this problem before or thoughts on what it might be?

Any warnings pop up on the dash ?
Any specific noises?

Might help guide you to a proper thread of similar issue

 

[cjlewis]

zero codes, no specific noises or dash lights.

There have been others on here in the last couple months with similar happenings. Not sure of the post names though

I few of us have had our engines quit while driving without warning. Failure ended up being a failed rod bearing. My dealership ended up replacing my entire 6.2l engine. My vehicle had 3400 miles on it when the failure happened.

Not sure if it is the same issue or not. 2023 Yukon XL with 3.0. Truck shutoff going 50mph switches to neutral will not restart till you can place in park. Dash says reduced acceleration, once in park vehicle can be restarted. Service Engine Soon light on. Dealer is saying fuel pressure control module, not sure I believe them

You can always look through OnStar and confirm the codes.

This EXACT thing happened to me yesterday in my 2021 Yukon XL Denali. I couldnt even put it in Neutral. I had to have the car towed to a closed GMC dealership in Clearwater and then rent a car to drive home to Jacksonville. Such a frustrating experience and no idea what's up with it. I would try to restart it but it acted like it wasnt getting any fuel (even though there is a full tank).

if it frustrates you then it might be time to learn a little bit more about the vehicle and it how works. that way you are less likely to be dependent upon the dealer to fix it, sometimes there is no way around it but a lot of things you can still do yourself.

Hi I also have a 2023 Denali ultimate today I was driving my daughter home from school and it just stopped running in the middle of the road. It went into park I couldn’t not change gears not even into neutral. A message appeared on Deb conditions not suitable to shift anytime I tried to get it out of park. I was literally stuck in the middle of the road. I also already had the battery replaced two months ago. It doesn’t even have 8,000 miles on it. Did you find out what the issue is with your car?

What was the issue and resolution? I was driving yesterday and noticed I couldn't accelerate, the car forced into neutral and put an error message that said "press start again". I coasted to a safe place and tried to start the car. At that point, nothing came on except the aux, the engine wouldn't start or even turnover and it was stuck in park and the message said "conditions not correct for shift".

@Kikilett Unfortunately the OP has left the building. Has has not been here since November 2023.

What did it end up being? Same thing happened to my 2021 Yukon XL Denali today.

Same thing happened to mine today. What did your issue end up being?

Mine did the same this weekend. Dealer sent a tow truck and hauled it back.

Mine felt like a slipping transmission just before it died. Had a noise like a bad belt, but couldn’t find any that were loose. 31k miles on a 2023 I bought 23 months ago.

The bad belt noise, did it do that right when accelerating from a stop? My ‘21 just started to do that…doesn’t feel like a slipping transmission but just hear an odd chirp like from a belt all of a sudden.

I was 45 miles into a road trip and had just hit the hill country. Was running fine then I had to slow down for a turning car at the bottom of a hill. Felt sluggish getting to speed up the hill, got to about 75mph but turned down the radio, heard the noise, backed off accelerator, it went away, hit it again and the car died. All happened in about 45-60 seconds with no warnings beforehand.

Just to update, my engine is seized. Glad it’s in warranty but that’s 2 out of my last GMC’s that lost the engine before the warranty expired. Other was a diesel 2500.

Oh well, gonna let them replace it and keep driving it. Should get a new warranty at zero miles.

That’s just nuts. Not good at all.

Hopefully you don’t have to wait too long for a replacement.
