Saw this on GM Authority:


I looked on the My Chevrolet app and my 2021 Silverado Custom Trail Boss with the 6.2 shows this recall outstanding on it. Wonder how long before I get a letter from GM or call from the dealer to bring it in. I'm at about 31,600 miles with no issues. I changed the oil at about 1000 miles and have changed it at 6K miles since. I've put some strontium magnets on the bottom of the oil filter(Purolator Pure One or Boss) and cut the last two open after I bought the proper tool and I was surprised at the amount of metal paste on the bottom of the can where the magnets were stuck to. This was just the last two most recent oil changes. Wonder how bad it was on the first couple changes. I also get some pretty nasty looking gunk in the JLT catch can. Can't imagine that helps things any going back into the motor.

bearing or ring metal (material ) ? if worried...send in a sample and see, certain metals are normal.

although, i am one that does believe... it the engine is spec'd properly, the internals do not touch each other as you do have a fluid film. with the short exception at start up...maybe.
 
Ignorance talking here but is the 6.2 and 5.3 basically the same engine? The power output isn’t hugely different.
 
Bore and stroke difference. Don't believe they share any internal components in the block. So the bearings are different between them as well as connecting rods which this appears to be related to vs the lifter failures that both 5.3 and 6.2's suffer from.
 
Thanks for the info GETGONE. I'm in the middle of a GM buyback and I will be looking to purchase a 2024 3.0L I6 Diesel LT Trail Boss. Does anyone know if there have been any major issues with this Powerplant?
 
GM ISSUES...these are off the top of what i see the most common to be

5.3 & 6.2 Possible lifter failure, 10 spd trans issues
6.2 crank & rod bearings CAN be out of spec
2.7 it has some but dont follow those to close
3.0 trans temp issues, some fuel system (if i recall)
 
This is a write up from Car And Driver

  • General Motors is recalling 887K full-size trucks and SUVs with the 6.2-liter V-8, as the engine might be defective; a stop-sale has also been ordered.
  • The recall list includes popular models like the Cadillac Escalade, Chevy Silverado 1500, and GMC Yukon—all of which are 2021–2024 models.
  • The problem stems from internal manufacturing defects, and vehicles must pass inspection or possibly require an engine replacement.
Earlier this year, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into GM trucks and SUVs with the 6.2-liter V-8. This came after the federal agency received 39 complaints regarding engine failures. While that investigation is still open, GM has now reportedly recalled 887,000 vehicles with possibly defective engines and also issued a stop-sale order for affected vehicles in dealer inventory.

The recall affects many popular vehicles, which include the following 2021–2024 models: Cadillac Escalade and Escalade ESV; Chevy Silverado 1500, Suburban, and Tahoe; and GMC Sierra 1500, Yukon, and Yukon XL. When equipped with the 6.2-liter V-8, they can experience engine damage that could lead to a loss of power or even complete engine failure.

The issue stems from internal engine parts (crankshaft and connecting rods) that were damaged during the manufacturing process. As a result, all the vehicles involved in the recall will need to be inspected. If they pass the inspection, the dealer will replace the oil filter, oil cap, and add higher-viscosity 0W-40 oil, according to GM's internal service bulletin for the recall. Engines that don't pass inspection will be repaired or replaced.

Car and Driver has reached out to GM for more details about the recall, and we'll update this story with more information when we get a response.

I have the 5.3L but i'm curious why they want to add higher-viscosity oil, wondering if its something to consider for my engine
 
Because the recommended 0-20w doesn’t provide adequate lubrication and is only used to squeeze out another .001 MPG to satisfy the EPA.
 
My '22 VIN is confirmed (on experience.gm.com) as part of the recall, but I went to the dealer yesterday and they told me it will be a month or more before they start bringing trucks in for the "correction" procedure.
 
Just got off the phone with the Customer Support Rep. at the NHTSA office and was told that the Automotive Manufacturer has 60 days to get the Recall Instructions letter to its customers.

All about displacement. So many factors play into it. Different scenario, but I had a Ski-doo 900CC Ace snowmobile comparable to the 1200CC in a lot of ways. However the added weight just didn't work for me.
