Thinking of selling my new 6.2L Denali...

[Rickjk]

I have the 6.2 in my 2016 Yukon Denali. 73,000 miles. No issues and I love it. Keep your vehicle. You will lose money.

In October of 2023 I purchased a 2023 6.2L GMC Yukon Denali. I have only put 9,100 miles on it and am thinking of selling it. I am seriously concerned about the engine issues that these vehicles are having.. I wish I knew what % of these 6.2L engines were failing so I could decide if it were worth the gamble of keeping it. In any event, I paid about $92K for it and put a $1700 set oz Yokohama Geolanders on it. If I were to sell it what is my best avenue and what should I ask for it? Craigs list? Facebook Marketplace? I guess another option would be to trade it in to the dealer for a model that is not having this issue..

I've had six new Tahoes and Yukon's since 1995 and were all excellent vehicles all with the 5.7L engine. So in September 2023 I purchased a new 2023 Yukon Denali, nice vehicle but I was a little disappointed how it drove compared to previous ones. Also there was no handle on the "a" column of the passenger front seat which made it extremely difficult for my short wife to enter and exit the vehicle. OK, I can live with these small problems. Then I started reading about the 6.2L problems and discussed it with the service writer at my local GMC dealership. Here's what I was told, GMC has a program setup if your engine fails they will toe it to the nearest GMC dealer and replace (not repair) and order you a new engine. The service writer told me it takes approximately six months to get one as the engines are backordered, they will supply you with a vehicle. In the mean time you are making monthly payments for a very expensive that you cannot use. The service writer added they replaced six engines in the past 5 months, one made it about 20 miles and failed one made it a couple of months. I was told by one friend when his engine failed it just stopped, no warning. My 2023 Denali was 9 months old with 8,000 miles. I traded it in for a 2024 Lincoln Navigator and couldn't be more pleased, my opinion is it drives and rides and is quieter than any of the Tahoes and Yukons I drove for over 29 years. I must also mention I am a diehard GMC individual so the choice wasn't easy, my advice is to take a test ride in a Navigator, if you like it as much as I do, trade the Denali in and save some sales tax as opposed to selling it outright. I now have just over 6,000 miles on it and could not be more pleased.

The new Navigators are pretty sweet. Had my eye on a blue-on-blue… couldn’t get onto the $115k price point and by the time they called me willing to negotiate and do 0% I had already bought my 2018 Suburban… for less than $115k lol

This is pretty good feedback. I don't have any immediate plans to get rid of it. If I were going to get rid of it, I would be replacing it with a GMC pickup with a gas engine.

Pretty sure the pickups have the same engine problems unless you go with an HD and get the 6.6 L8T. Otherwise, if you are thinking of just a 1500, I am recommending sticking with the truck you have. Hard to beat it and would be in a similar boat still.

Haha I think a lot of ppl have weighed in tho. Good luck with the choice and keep us all posted!

Oil change every 15k miles? Is this a typo, or do you really keep the oil in the motor for that many miles?

I changed mine every 4500,full synthetic and it grenaded at 27,000. I would never go 7500, let alone 4500 as these things are known to consume oil also

Why don't you just get an extended warranty from your dealer. They do an inspection to make sure nothing is wrong then you but it.

The oil consumption on mine (both my current 2021 and my 2015) went down to almost nothing when I switched from 20 weight oil to 30 weight Amsoil. I am in Florida and my mechanic is adamant that 20 weight oil is too light for our heat.

Jan 17 (Reuters) - The U.S. National Highway Traffic Safety Administration said on Friday it was opening a preliminary probe into 877,710 vehicles manufactured by General Motors (GM.N), opens new tab, after receiving reports alleging engine failure.
The investigation covers certain Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon and Cadillac Escalade trucks and SUVs from model years 2019-2024, equipped with the L87 V8 engine.

Man oh man your worried about essentially nothing. There are hundreds of thousands of these motors made every year. We are talking a abysmally low failure rate. Does it happen ? Absolutely. Has it always happened? Absolultley. Will it happen to you? By the numbers probably not unless you just have bad luck.

I've bought tons of vehicles over the years and forums can sour some experiences when all you do is concentrate on the issues.

I remember my 1st gen 2002 mini cooper s fondly. But holy shit the forums would have you think they were made of paper. I never drove a car harder and tracked it more than that car and it held up! And now? 1st gen minis and all their faults are held to high esteem.

The same thing happens with many gm vehicles. C6 z06. Holy shit the heads! Don't buy dont buy trade it in! Guess what? People love them and it rarely happens and the soft head issue is way more prevalent than the lifter and bearing problems of the 6.2

Then of course you have people that tell you the ten year old or older stuff us better when guess what ? It isn't and they broke a lot. I'm talking about things that happen constantly. Hvac issues. Trans issues. Steering issues. But now here in the forum people think they are good because they are cheap and they didn't buy it new.

Luxury brands are even worse. Don't buy a bmw or Mercedes or insert brand here. Reality is even the new land rover defender is way more reliable than a cursory forum search will show.

Sure there is an investigation as there should be on 6.2 failures since the failures could be a safety issue but there won't be a recall on a million vehicles with the 6.2 if anything even comes of it.

If you like it. Keep it. If it keeps you up at night sell it. The beauty of GM products is they are easy to fix and the beauty of new is you have a warranty.

Take care and good luck on your decision.

Admittedly I was getting a bit anxious about the news concerning the engine. My Tahoe is only 4 months old, so to speak. It has 9,000+ miles on it now and I am getting ready to take a long trip. Supposedly the oil range can be up to 7,500 miles between oil changes but the dealer wanted to change oil at 5,000. Is that the best route to take to hopefully negate some of the concern about engine failure: oil change every 5K?
