I am looking at possibly getting a recent used suburban and the higher trims only come with the 6.2L. I am on my 3rd 5.3L and very comfortable with that engine. I know tbere was a recall on some 6.2s but not all of them.

I am looking at somewhere. Between a 22 and 25 suburban. Is a 6.2 a no go, or are issues overblown?

Overblown imo. Run 0w40 or 5w30, plug in a range afm disabler and enjoy actually having a suburban that's not gutless. Oh also enjoy buying 91 octane

Stuff I have seen online indicates there is possibly a bad design of the oil pump system when used with the 10 speed auto that keeps the engine at low rpm to save fuel which also keeps the pressure of the 2 stage pump low, but that doesn't match with the actual loading on the engine in all low rpm scenarios. There is some chance not enough oil is getting where it seems to go to maintain the necessary coating of friction parts and…you get metal wear, which snowballs into a catastrophic failure in a small but not insignificant portion of the engines. That's the latest theory. The oil viscosity changes are only a partial solution, reprogramming the engine rpm ranges to engage the high igher flow operation of the pump may help also, but neither is a true solution. The most likely long term solution is a pump with a higher flow and pressure design in all modes of operation.

My wife has a 21 Denali XL with every single bell and whistle. Amazing car while we needed long road trips for kids sports etc, but it had both lifter packs fail and replaced by GM due to faulty part which was well known and the transmission went out of on 35 at 105k no chance to repair it. 8500 later new ****** and 60k warranty on it.

Takes premium fuel but every other vehcile we have is a diesel so its less on fuel than those.

It just sits in our driveway right now prolly looking to sell it, enjoy it alot on long road trips will never buy another one unless its in warranty or transmission has been done. just my 2 cents

On my second 6.2L Yukon with no issues. I really enjoy it, just make sure you have a warranty for 100K or more.

I have a 2021 at4. I had lifter failure at 10k miles. Warranty would only replace the lifters on the bank that failed. At 74k I had lifter failure again that lead to a total engine replacement. Even though I had an extended warranty it still cost me 4k for expendables and 30 days of rental car payment. While the new engine came with a 100k warranty I still don't have confidence it won't leave me stranded again.

We bought a 2022 Escalade from Sewell. They said the inspection and anything related to the recall had been done and its warrantied to 150K.

I'm not too concerned

That stinks. I have the same truck with 80,000 miles on it and an extended warranty that goes to 100,000 miles but I have not had amy issues yet.

With the cost of new vehicles, especially new trucks, I am considering driving it until it fails me and replacing the engine if necessary. It seems like it would be a lot cheaper than buying new.

Do you unplug that disabler when you service it?

Like when I change the oil or trans fluid in my driveway? Lol I don't take my vehicles to the dealer. I suppose if I ever have to take it in for something warranty I would unplug it and keep it with me

I love the 6.2l. it gets 18.5 to 19.5 MPG (high octane) and really pulls compared to the 5.3

mine is in a 2018 silverado. I had the cam and lifters replaced on the one i have now. Delete the AFM as soon as you get it.
