6.2 not a good idea because of issues?

[xycrazy]

I found a nice Chevy High Country but I heard about issues with lifters and misfire.

So I'm wondering how reliable the 6.2 in particular is compared to the 5.3. I have a 2017 5.3 and never had any misfire or lifter issues. Thought that the V8s are a super reliable engine with millions of miles on it.

So what is the truth here? Shall I better not buy a 6.2 and opt for a 5.3? Shall I buy a Diesel instead?

I'm afraid of having the truck in the shop all the time and I'm unsure right now If I even should trade-in my 2017 Yukon for a new car that is known for issues. Or am I overthinking it?

My understanding the same lifter are used in both engines I think diesels are pretty bullet proof.

 

[decembersend]

Yep same lifters are used in both. Personally if I were in the market I would do diesel for power, towing, fuel economy (once tune and deleted). But if you want to stick to gas go with the 6.2L and then either do a AFM/DOD hardware delete or buy a AFM/DOD disabler and prevent it from coming out of V8 mode.

I’ve had a 6.2 since 2007 with zero engine issues. Just bought a 5.3 hoping for the same.

3.0 Dmax is the overall best choice for this vehicle if you are going to rack any miles at all. Mileage is at least 40% better and its smooth as butter.
Only downside.. they are rare as hens teeth...Good luck trying to find one...

Question Regarding this, I have a new 2022 Silverado ordered, was built today actually and is the 5.3 and they are taking off the DFM I assume to save chips. Isnt this a good thing? I thought about the diesel, but there’s limited builds on those and I woulda been waiting a while I think...

Well the only diesel that I can find is a GMC Yukon SLT with 5k miles on it. Nicely equipped with Brake Controller, Sunroof, RSE, white leather, etc. However the price is heavy... $84K - I think that's roughly 14-15k over MSRP lol

Car gurus is showing 909 gassers and only 125 diesels. Definitely not very common overall haaaaaaa.

Heres a brand new denali diesel with an msrp of 84k and its listed for 77k (although i find that hard to believe and probably not that true sale price).

Same lifters and issue with both motors. Last May we rented a 2021 Suburban to go cross country. The truck was being brought in from the airport rental store. As we stood in front awaiting here it came limping in. Yep brand new-- lifter went bad. We were packed and ready to go. Had to wait till 4 hours later when they found another. He told us they had two new ones both bad lifters at the dealer. So our trip was delayed one day, and we put 9000 miles on that truck. Beautiful ride, was flawless. BUT believe me I was concerned in some parts of the country!! We came home and bought the only 3.0 diesel we could find as the market went nuts! Good luck

How do you notice a defect lifter? What are symptoms?

 

[R32driver]

We had a 2011 suburban with a 5.3 for 10 years and the only issue it ever had was a broken accessory belt tensioner that cost me $60 and took 15 minutes to replace. That said I went with the 5.3 in our '21 and it's been great so far but only at 10k miles so far. Lots of horror stories about failed lifters but will cross that bridge if/when it comes.

As much as I don't like the sound of a wet belt for the oil pump I think I would lean towards the 3.0 diesel at this point given known issues with the gassers and the great fuel milage of the diesel. Only downside is diesel fuel is and will most likely remain more expensive than gas but the added fuel mileage of the diesel pretty much negates the added price at the pump

Lifter issues are with the new trucks....

 

[Dustindu4]

The 6.2L lifter issue was corrected almost a year ago. Fake news

There is no symptom. It's a failure. When it happens there is no doubt you will know. Engine light, misfire, loud tapping, engine shake, depending on intake or exhaust smoke from exhaust. When it happens, your stuck. When we were out in the middle of nowhere in Utah, Montana and Wyoming it was a concern. Great truck, great ride, Gm is fully aware its a subpar, defective part or they would not have a memo to replace all the lifters.

We had a 2013 suburban 5.3 2wd 118,000 miles when I traded it recently.....the best truck ever! Since new, it only required a master cylinder. They did have a AFM lifter issue, but with our maintenance nothing! Ran like a sewing machine. Considered a cam and lifter job to go the distance but the fuel mileage was the killer. Solid, reliable truck, miss it. But with todays fuel prices, I am loving the 3.0

Ok my friend was at the GMC dealership and got told that GM's supplier has left the parts outside when COVID hit. So parts got wet and were impacted by the climate. That has led to bad part quality which they figured later. That's obviously causing the lifter issues. And that's why it only happened during a specific timeframe

Huh? So what about the lifter issues prior to Covid? Were those parts left outside as well?
I’m not buying that bullwash story; as told from the stealership in order to help sway the public or convince them that it’s a “new” issue. Don’t take my word for it though, ask any of the hundreds (prob more like thousands) of 2007-2012 owners who’ve had this issue, and long since corrected it after many failed attempts or engine swaps.

Please don’t think this reply is an attack on you. I just had to laugh at the idea of someone from the dealership either believing the info passed down to them from higher, or they convinced themselves this was the truth and have passed it off as such since that time. I’m not saying that all dealerships are shady; however, by this point even those who are good should be well read-in on this topic.

The problem in my mind is outsourced parts that aren't under strict quality control which if made in house a lot of these problems with quality of parts would be addresses in a timely manner, and customer satisfaction would be at the top.

The problem in my mind is outsourced parts that aren't under strict quality control,
which if made in house a lot of these problems with quality of parts would be addressed in a timely manner, and customer satisfaction would be at the top.

If customer satisfaction were top priority, GM would:
1. compare the profit margins they're making off of Escalades / Denalis, vs Tahoes / 'burbans
*(Escalades / Denalis are just Tahoes / 'burbans with fancier bits)*

2. correctly assess that the 6.2L V8 is a fancier bit,
from which GM profits even more than they profit off a 5.3L

3. Spend another $500 per engine to prevent the engine failures in the first place

4. snort slightly shorter kokegain rails off of slightly cheaper hookahs with slightly cheaper fake bewbz
to offset the temporary lower profits

*(How much money would one save by buying a Tahoe / Yukon, stripping it, and
replacing every visible piece with an Escalade-upgrade?)
