for any 6.2 owners out there you should look

Yep. My 2024 Denali(Mount McKinley now I guess) is on the recall list.

I saw this - I have two friends who own older versions who have both just gone through major expenses with their 6.2 motors. One, camshaft failure at 140k, the other, a cylinder failure at 80k. The one got a new camshaft only to have the retainers not be torqued correctly and failed after only 3k and the other got a whole short block replacement. Neither are too happy to see the recall only covers 21-24 models.

yes and the parts are the same from 19-24. they admit manufacturing defect and solve it with thicker oil. can't make that shit up. maybe a can of stp is next

What’s the main issue with them?

I heard it is something to do with the inferior crankshaft and connecting rods.

Yeah, I was thrilled to see this in the news earlier this week

My '21 Denali has been excellent, outside of the lifter bank issues I had very early on (replaced). This bulletin doesn't exactly give a guy a warm & fuzzy feeling. I just had it in for an oil change 2 weeks ago so I guess it'll go back again and see what they say. I'd actually be OK if they said I get a new engine, but I don't know how thrilled I'd be with the downtime - or knowing whether or not it could just lead to other issues.

The fix is thicker oil? Oh boy, that would give me a lot of confidence.

wait till you see the price of your next service

I left GMC around 11-12 years ago and won't hesitate to do it again, if that's what it boils down to. Granted, I'm sure I'll take it in the shorts from the other brand/dealership trying to unload my truck (when the stop sale is done).

Anyone get their 6.2 looked at yet? Seems the bulletin / recall is official now, based on this ... I thnk?

I gave the dealership where I purchased my '21 a call, and the service dept. rep that I chatted with asked me if I was calling about the "Propulsion Bulletin" (which is how it's worded in the link above). I confirmed that's the one, and she said she looked up my VIN in both the GM system and the NHTSA system - neither had my truck's VIN listed as part of the recall. So I dunno

Gonna give it a little more time and follow up again as I don't know if I trust, 100%, the person I spoke with today.

Crankshafts mfg in a Mexico plant were cut improperly. Oil clearances are too large resulting in oil film breakdown. The 0W40 oil is but a bandaid. This is what happens when critical engine parts are farmed out to $2/hr workers. This is a continued shitification of automotive products. Wait until the cost cutting to adjust for tariffs hits the automotive industry.

Powder metal connecting rods. No thanks

Does anyone make a decent 1500 pickup right now?

Toyota's new engine is shit. GM has this going on. Ferd has their egg shell Ecoboost. Rams like to grind away at their camshafts.

Nissan, maybe?

not to mention ridiculous prices for a half ton. 60k is way too much , and they go in to the 90s. at4x is 94k. overpriced and garbage too. that's a fuckin right there. so here is how the recall is being handled . 21-24 6.2. if you have recall we first check for replacement engine. they get inspected by serial number. when the truck comes in it gets hooked to a scope looking for a vibration frequency. if it has this it fails and gets an engine. that new engine will still get 0w-20. and no warranty extension. if it passes , it gets a new oil cap, 0w-40 , and filter change. that will get 15/150 warranty extension , but currently it reads like connecting rod failure only. so no lifter coverage. they managed to get people to buy overpriced trucks, but fell short on delivery. now anyone with a 6.2 and a ten speed should be concerned. 4 years plus of building an engine that they had to know was flawed. don't forget how many 21 trucks were sitting waiting for chips

I’ll be looking for a newer to me sometime in the next few months - 3/4 ton most likely. Probably should start researching a little.

I’d locate an older vehicle that’s in good condition and fix all the known problems and weaknesses. Then drive it forever. A relative just picked up a 2001 ford F350 with the 7.3. 43,000 miles. Lived its life in the state of Oregon. He paid $43k and will stick another $10k into the motor and chassis. He’s 65 and plans to be buried in it.

The shitty part with this 6.2 recall is, I've absolutely loved my truck. Yeah, I had both lifter banks go out on me early on, but those were repaired and the truck has been all I could ask for in the 50K+ miles since that issue. Pulls my trailer(s) great, pretty decent gas mileage when we use it to travel, rides extremely nice, etc. Having this recall issue hang over my head, sucks. I always figured if I'd have issues with it (beyond the lifter banks) it would be some electrical gremlin, knowing how much electronics go into these things. I'm definitely not a fan of the bandaid GM plans to use. If we weren't in the process of buying another vehicle already, I'd wait for the stop sale issue to be done with & trade my truck on something else. But I'll roll with it ... for now.

Just put $3K+ plus into our Explorer with gen 1 3.5L Ecoboost. Water pump, cam phasers, timing chain, tensioners, guides, etc. 12+ hour job, for a $100 water pump.

Seriously? I think my Sea Doo even has forged connecting rods.

22+ F150s have aluminum bodies and the fixed 10 speed transmission. The 2nd gen 3.5L ecoboost is garbage. 5.0 seems ok if it doesn't burn or leak oil. The 2.7L Ecoboost would be ok too if you don't tow a lot. Many reports of those 2.7s going over 200k miles.

Do like @X2700 and haul a 20 year old truck up from Arizona that still has a black frame and not a spec of rust.

That’s what I have now, 20 year old truck that’s pretty reliable, gets shitty MPG’s towing, and driving for that matter, but rusty as hell. I don’t want a yard Princess, and most of what you find around here is just that. And people want top dollar for it…

Hear ya. My 2012 F150 I think I paid $12K for. I don't tow much but it pretty much gets used as a dump truck. Rust will kill it eventually.

With the price of the new stuff and all the issues every manufacturer is having, I just don't see a reason to buy something newer.

Our 2017 Exploder 3.5L N/A started smelling like coolant and had corrosion starting on the hood at 80k-ish miles, so I cleaned it up and traded it off before the coolant smell came back.

Not sure going with another Exploder was the right call, but it is what it is.

So far the Silveraydo with the 5.3 is doing good. Can't really justify trading it off given what dealers are offering for trade and what a comparable new one costs 4 model years later.

I can tell the dealers are hard up to move inventory. Weekly we are getting letters from several telling us how good the deals are right now for trades.

My last three American trucks were such a disaster I am done with domestic garbage.
