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?

It certainly can't hurt.

I love this entire post and agreed wholeheartedly but this part is where you lost me. Land rovers *initial* quality may be great. But they are truly trash once over a certain threshold. Don’t care how well they were maintenanced.

Like the old saying goes, if fluid ain’t underneath it, fluid ain’t in it. (Had a 2000 Land Rover discovery, very FUN truck, but one of the worst vehicles i ever owned).

I still agree with the main sentiment that forum naysayers can make you overthink the most trivial of things.. let any particular forum tell it, and you’d think there is no reliable vehicle ever made.

Anyone planning on running OCI over probably 6000k miles should probably be performing oil sampling at some fixed interval to determine if the oil contamination is becoming a problem.

A kit like this if the tube will fit down the dipstick can be used to obtain an oil sample. I know the earlier 6.0l had a flattened dipstick tube and could not fish anything inside it.

But for the money that is spent on oil analysis, you might as well just change it. In most areas you can get a quality synthetic oil and filter for about $50 if you are doing your own oil changes. There are other reasons to have shorter OCI in these newer DI engines. My plan, and this is my plan, is not to exceed 4000 miles between oil changes. Some may think this is too often, but this is my plan. I really do not trust the fuel contamination and oil breakdown and carbon or potential sludge build up with ultra long Oil Change Intervals. Unfortunately I think the DI engines introduce a lot of cylinder oil wash down and carbon buildup with the low tension oil rings can be problematic. Not sure there is a real solution for much of this.

All the marketing hype about 15,000 mile oil and 15,000 oil filters is not something I am going to buy into.

Dude 2000 and 2025 is a completely different animal. That's 25 years of making better processes that are not secrets to any one manufacturer. We live in 2025. The only reason a car is bad is because of a supplied part that is out of spec. Not bad design. It's the same issue that has plagued GM for a long time.

& exactly how many land rovers / range rovers have you owned . . .

4. We love our range rover sports. Never had any issues except once with the air suspension compressor.

I was never really a big fan but my wife was and she had one when we met. I was convinced it was a ticking time bomb and it never went off lmao. So we kept getting newer ones.

I'm on the fence about ordering a 2 door defender with the supercharged v8 for a compact fun vehicle.

We got rid of my wife's last range rover for the yukon as we needed more size. And have ordered a XL cuz we need even more space lol.

I like the extended defender too but it's too small..still cool tho

You haven’t stated how old the Rovers are or what the mileage you’re getting rid of them at.. but if you are buying new LR/RR, riding them 30/40/50K and then trading them in for new ones, congratulations.. you are LR’s target demographic.
2000 LR Disco leaked every fluid possible. Don’t matter how much TLC you put into it, it was always some new weird issue. interior and body were absolute MINT! This was almost 15 years ago, so it’s not like we’re talking about a 25 year old truck. Sold it to a scrapper.

2017 RR HSE, entire infotainment went haywire at 60K. Big pita. Truck ONLY serviced at Land Rover dealer since new. Has like 68K on it now, sounds like a pawn shop dirt devil with low batteries.

My personal experience isn’t forum fearmongering. If you have had great luck with LR/RR, buying them used and riding them 100’s of thousands of miles, more power to you . . . but if so, i think you are the exception and *NOT the rule. Plus, i am not sure how much stock in ‘reliability’ i would put in a company that refuses to service their own vehicles that are older than 8 years from the newest model year.

Meanwhile, tahoe/burb/yukon have pretty much had a solid reputation for being generally reliable and capable trucks / workhorses since their inception, .. the whole 6.2 grenading itself with no warning phenomena seems to be the exception, not the rule.

Yeah man im not sure what you are trying to argue. You had bad luck. Sorry.

It happens. Somewhere there's a guy with a broken down toyota corolla screaming to the heavens....it happens to all.

We kept them till we got bored. Purchased new. Anywhere from 80 to 165k miles when we got rid of them.

Land rovers main current objective is to shake their reliability concerns so hopefully that continues to improve.

I think you are nuts. That is a nice car. Your risk is the electronics, as it is with any car made today. This forum is a very small subset of GMC Yukon buyers. A few have had problems. That is what you read about here. But it has nothing to do with the vast majority of Yukon's out there regardless of year. My 2011 with AFM only went 203,000 miles before I pulled the plug and bought my 23. And that was with AFM that was more primitive. The Queen put most of those miles on, but when I drove it on vacation it got exercised. Nothing, as in NOTHING, ever happened. Best car I ever owned.

I bought a 2023 equipped like yours. It could be going to hell behind a wrecker. I can't tell you until I get 200,000 miles on it. So far with 30,000 miles nothing has gone wrong that the dealer did not cause. And it had to do with a bad front end alignment. Directions were in the owners manual. Tech could not read, but few of them can these days.

But bad stuff rarely happens. I think the weakness on most if not all cars these days is the electronics. Regardless of make. That is why I have the extended warranty. I will continue to drive a 2023 GMC Yukon Denali XL.
