2023 Yukon Denali 6.2L, Dead at 3600 miles

[NoYukonYet_1Jeep]

Picked up our truck (finally) after a 9 month wait on the custom order -January 9th. 2023 Yukon Denali with 6.2L. Logged some good mileage, really enjoying the vehicle and all it has to offer. 3600 miles later and exactly 1 month to the day on Feb 9th -

Driving home 1 block from my house, engine shuts off, car goes into neutral and that’s it. I rolled up the hill and pulled over to the curb. Both Kids asleep in the back on an 80° day. Battery good. Car wouldn’t turn over at all. First flatbed couldn’t get us because the car was locked in park and didn't want to damage drivetrain. (3pm) Service dept at the local dealer knew no way of manually unlocking the transmission / getting the car out of “park”.

Fast forward six hours later (9pm) via GM roadside assistance, second truck arrives with correct dolly equipment, all four wheels off the ground and away we go. Cars currently sitting at the dealer with no status updates (after 1 full day) other than potential serious internal engine issues.

What bugs me is zero warning lights, zero signs of issues, really zero anything to clue me in that my vehicle is about to fully fail. With all the tech available, I’m just dead in the water on the side of the road with two sleeping kids in back .. luckily my brother in law came to the rescue in his Tesla.

My first GM Vehicle and really a pretty awful experience. Had high hopes for the 6.2L and all of the great tech this Yukon had to offer. More to come here

I’ll add I asked the tow truck driver if he had a code reader so we hooked it up and absolutely zero codes. checked 5 different modules that came up on his scanner and nothing.

1 month old, $87k truck. useless pile of metal right now.

You should have a rental soon and an answer as to what happened on Monday or Tuesday.

Something similar happened to our new car once though I was alone. Took the dealer a month to find it, a bent pin on the connector to the computer. I enjoyed putting the miles on the rental car while waiting.

 

[NoYukonYet_1Jeep]

did you just rent on your own and await reimbursement? Seems like GM will offer $25 / day. And my auto policy will give us another $31 / day. Not getting a Yukon rental anywhere these days for $56 / day..

This dealer only has 7 loaners and none are currently available

If you read page 376 in owner's manual in link shows procedure for flatbed vehicle. The tow company that dealer sends should be able to get vehicle set to load but they didn't but also didn't damage vehicle buy not knowing just a lot of frustration for you.

Think somebody else recently on this board posted a similair thing. also brand new. it will be fixed i’m sure. possibly fuel pump.

What a total bummer. Sorry to hear that. Gotta love corporate greed and cost cutting!! I'd let it play out and then start going after things like extended warranty etc. If it gets really ridiculous, then I'd ask GM to take their paperweight back.

I've been a loyal GM guy for 30 years, but what you get nowadays for the exorbitant cost and all the issues makes me want to consider a different brand when the time comes. I hope they monitor sites like this because it's almost laughable at this point how many super expensive rigs have died.

Keep us posted

Lot's of similar stories on here... I would have thought/hoped quality would improve since June 2020 when I purchased my first 2021 Yukon. I've been waiting 2 weeks for a stupid washer fluid pump. A part, which I would think is part of every GM Vehicle and easily acquired.

Wife and I went looking for another vehicle for her yesterday and I think we're set on the "tried and true" dinosaur Lexus GX 460. It's still made in Japan and drivetrain is old school. The older I get; the less problems I want to deal with, so GM products will likely be off our list of vehicle purchases. At least having one vehicle we don't have to worry about....

give it some time. To early to tell. Don't worry once you have your yukon back you will be rescuing your brother in law in his tesla in short order so no worries there.

No codes probably a fuel issue. Good luck!

I came here to spread word and I do know that GM monitors forums like these.

I really hope this is not something common at all - and I fully understand people don’t always come to forums to spread all their happy experiences, but this one was quite ridiculous.

Appreciate the suggestions. I will definitely look into negotiating an extended warranty or see what GM will offer as compensation.

Wouldn’t it at least turn over if it was fuel pump ? Barely even makes a click when I attempted to start it

Yeah - this is exactly what we did when 2nd tow truck arrived. Flat bed was not ideal for a car locked in park.

We used the dollies which was the only way to not damage the drive train, per the local GMC dealer .

Battery?

 

[Stbentoak]

Give it a chance. I had a new Grand Cherokee and it was in the shop like crazy the 1st 6 months. But after that for 6 years it settled in to be a great vehicle…..
At least give them a round or two to fix it, then call the shots later if still unhappy…..

 

[NoYukonYet_1Jeep]

This is is good advice. I’ll try to stay positive and be patient while dealer diagnoses.

We did have a road trip coming up which would have been quite comfortable in the new Yukon which we’ll now have to rely on borrowing the in-laws vehicle . Some inconveniences for now, hopefully we’re back up and running soon.

In owner's manual there is way to put vehicle in car wash mode that will let them flat bed and two holes in frame to winch with.They will have to do that at dealer to move in service bay probably.

Interesting- I see it here, page 207-208 of the manual. It does specifically say to not use this for towing though. It also looks like the engine would need to be running in order to initiate the steps for car wash mode. Wouldn’t have been an option for me in this particular scenario - no running engine.

Yea wouldn't use to tow but to get on flatbed would work.

Battery?

Would be amazing if it is the battery. Entire dash was still all lit and everything else seemed to be firing as normal which made me think battery was okay. The first tow truck also hooked up a jumper pack and let it charge for ~30 min and starter still wouldn’t crank.

Would think you’d get a low battery warning or if alternator died another type of alert. Was very difficult to troubleshoot on the spot. Hopefully more answers this week.

I have a brand new 23 denali ultimate that’s been in the shop a month. Battery keeps draining. Car alarm goes off, replaced glass w sensor in cargo rear and still problem persists. Onstar alerts say rear hatch lift gate door open as a part of the theft deterrent system. Techs at dealer call gm techs to trobleshoot but no GM tech has been out yet in person to assess the vehicle. Has 403 miles on it. Pathetic and frustrated. Dealer thru a battery at it initially was not the issue. Something in the electronics is draining. Not sure why GM is taking a month to get a tech out. Supervisor at GM says it takes 2 weeks to get a rep out and the dealer is the one who initiates it. Beyond frustrated. I’m in PA
