2024 6.2 engines

[Snowman4]

I know it’s been beaten to death I just really like the GMC or Chevy 1500’s.
 

I’ve been doing some every day and saw that some of the engines were put together in Mexico and had some quality issues, then they were going to be moving them back to the US. Has anyone had any issues with their 2024 6.2’s??

 

I really want to pick up a 1500 6.2 or order a 2025.

2024 6.2 with about 8k miles, no problems yet.  I had 2 previous 6.2s (2019, 2020) and no issues either.

I don't believe anybody has ever mentioned that the Mexico trucks have quality issues above and beyond any normal issues you might come across in manufacturing vehicles.  I know some of the early issues were actually on trucks built here in the states.  As far as the engines are concerned, they are pretty bulletproof other than the occasional lifter failure, and those lifters are in EVERY engine, regardless of location of assembly.

 

This isnt 1980, and GM, Ford, RAM, etc. all build vehicles in Mexico, and they are built to the same standards and requirements as US built units.

 

This being your first post, I wonder if this isn't a trolling post.

[Snowman4]

I’m definitely not a troll but if you look in the other post with about 5 or 6 pages their is a ton of people with 6.2 issues and that is where the Mexico built quality issues was brought and I read it. I’m just doing some research like everyone else.

I understand with this now being my 3rd post you could think that people are trolling but some people have just joined the forum and want to learn as much as they can before spending $60 or $80k

2022 and 2023 are known issue windows for lower end bearing failures.  2019-2021 is DFM lifters.  So far 2024s seem okay, I'd imagine whatever bugs they had going on have improved, but I've also noticed some dealers have hesitation on stocking 6.2 trucks now.

Don't forget lifter issues, from 2014 to at least 2023 they were still prevalent. But yes more concerning have been the lower end bearing issues, that seems to mainly be on 22 and up models.

'23 6.2 at 23k miles now, no issues so far.

2019 6.2 63k miles no dfm issues, oil lines replaced (leaking)

2023 6.2 33k miles no dfm issues but highway vibration issues

2024 6.2 1500 miles no dfm issues

I thought all 6.2's were assembled in the Tonawanda plant, outside Buffalo.

They are one of three Gen V small block plants.  St. Catherines Propulsion in Ontario, Canada and Silao Propulsion in Silao, Mexico are the others.

 

Tonawanda does LV1, L84, L87, LT1, LT2 and L8T.  The only 6.2 I know 100% exclusively rolls out of Tonawanda is the LT2 for Corvette.

Not VERY Prevalent relative to trucks sold...think of the volume

The bearing issue seems to be on MY23s...got informed of one case in Qatar...not sure about other Middle East Countries.

I would recommend to steer away until they fix the bearing problems...I hear fewer reports on the MY24s than on the MY23s...and there seems to be a change in the part number as well...so I think it will be sorted by MY26. 

 

At this point, better go to a MY22 LTD/MY21 6.2 w/o Auto Start Stop or DFM, or alternatively look at one MY20 or below (better option).

Some MY24s have failed as well....but there has been a part change recently in the midst of this. I suspect it may get fixed by the end of this generation...or at least reduced to lower levels. 

I still would not call the rate exponentially high...

Toyota did something similar with the Tundras...

Almost all the 5.3L and 6.2L engines are built in the USA.  Pull the windows stickers and it says right on there. My 2021 was built in Mexico (6.2) with the engine and trans made in USA.  The ones built in Canada go to Oshawa builds as its a few hours from the plant across line from Tonawanda.  I just looked at 28 trucks and all the V8's were made in USA, 1/2 the truck were Mexico and US builds. 

 

The Turbomax I4 is made in Mexico.
