Gm to stop selling 6.2 Ltr. trucks and suv's

[rwBrooks]

General Motors has issued a stop-sale order for all full-size pickups and SUVs equipped with its 6.2-liter L87 V8 engine built between the 2021 and 2024 model years, citing concerns over connecting rod and crankshaft integrity which are causing engine failures.

Key Points​

• GM has issued a recall for 2021–2024 full-size pickups and SUVs equipped with the 6.2L V8 engine due to potential connecting rod and crankshaft defects that could lead to sudden engine failure.
• A stop-sale order is in effect for affected Cadillac, Chevrolet, and GMC models, with inspections required; vehicles that pass will receive higher-viscosity 0W-40 oil and a revised owner's manual insert.
• 2025 models are not affected thanks to updated manufacturing processes, but the availability of 6.2L V8 trucks and SUVs remains limited.

This is interesting statement. Maybe I missed it in the other articles.

lol, I bet the 2025s are exactly the same. They just didn't want a stop sell or this recall on the current model year. Probably not enough 25s reported yet to make them include them. Average person only logs 12k miles a year.

What about the suggestion of going to a heavier weight oil?

Just because they said it, doesnt mean it's true considering how much they cover up to avoid paying out. How many 2025's with 6.2Ls are on the road with enough miles to know for sure they arent affected? If people drive an average of 12K a year, MOST would have less than 10k on the clock right now.

Is there an echo in here?

They may have replaced the rod or cam bearings, which i think would be easy to do. Just like the lifter issue, we don't see many of those issues lately, so I think thos bad parts were flushed frome the system..........maybe!

Always a possibility. However, If that is the case, why did it take them 4 years to do it? Guess we could say money for that one too lol.

Cause Mary Bad Bearing Barra wanted her $30M payday before she gets canned!

Yep. I have never thought it made sense to pay anyone $30M or anything like that. I got it you are over a billion dollar corporation but still. With that type of money Id work one year and retire damn it.

That was exactly my thinking. This stuff doesn't happen over night. Chevy could have simply switched to a different part number on the 25s and said it's fixed. If I remember right GM updated the lifters for model year 22 that was supposed to fix that problem as well, But we all know it didn't. Plenty of ZR2s had lifter failures. I know I thought it had been fixed when I bought my 22. Didn't take long before I started seeing lots of refreshed trucks with lifter failures online. Them saying don't worry the new ones on our lots are good to buy wouldn't overwhelm me with confidence, lol. Imagine people worried about it going out and trading for a 25 only to find out in 6 months they are in the same spot...

My post on the Recall Thread has some information.

 

[Waterdog]

I am nearly certain I came across one or two owners in some fb group I’m in that recently had a failure on a 25.

Pretty sure when they rolled over to the 2025 production the only thing that changed was the year designator in the vin.

These posts are really making us look bad on the 3.0 vs 6.2 thread

"The recall indicates inconsistencies in manufacturing tolerances that could cause premature wear or total engine failure. GM is advising that switching to thicker 0W-40 oil offers improved protection under high load and temperature, aligning with specifications seen in performance models like the Camaro and Corvette."


So the 6.2l is built at multiple facilities, although the article specifically mentions the Buffalo, NY plant as the source for the affected trucks. I wonder 2 things: is that true? If so, what inconsistencies in manufacturing tolerances are at fault? The process or the quality of parts?

If there really is only one plant making these, we wouldn't be able to discern which vehicle is liable to fail. If multiple plants produce them, it would be interesting to find out which plant had the highest fail rate and why...

I thought the Camaros and Corvettes had superchargers to make more power. I though that's where they needed higher viscosity oil.
