Lifter anxiety

[Onlyone]

What does that link explain about a lifter call me ignorant that's an explanation for a 20-year-old vehicle.
The valve train for our newer vehicles are much more sophisticated.

It’s not worth arguing with children. Let him win.

So this thing gets bounced up and down 1000 times a minute against a 300 lb spring and it's expected to last how many miles?

Well, I left the Ford camp and purchased a new 22 burb last July, love the truck. This forum is great for all info related to our vehicles. Is there a mileage range when this lifter failure occurs? Reading the lifter related threads is seems mileage is all over the board. I only have 3600 miles As the owner of a new Tahoe, I appreciate your anxiety. If you want a trouble-free engine, my best advice to you is to go out and buy a 2022 Toyota Sequoia. Those engines will give you 300,000 miles RELIABLY. Unfortunately, the new EPA doesn't like them.

Did they fix the turbo wastegate issue?

If I'm not mistaken, the really bad lifter issues were corrected for the '22 model year. I think the DFM system had issues from '19-'21, but they should have been fixed by '22.

My part time jobs have (2) 2021 Suburban LTs and (2) 2021 Yukon XL AT4s, and two had to have engines replaced somewhere between 10k and 15k. I haven't heard any issues with the '22 models yet.

The bad run of lifters were Sept.2019 thru March 2020 of Engine build date not vehicle build date. My 2019 Silverado was built in Dec. of 2018 and engine was built Nov. of 2018 I bought it in March of 2019. Our 2022 Tahoe was built in July of 2022 with an engine build date of June 2022 and bought 1-2-23. This range effects the 6.2 motor also.

The company that built these lifters and components were out of spec of what GM wanted is what they found.

Sequoia? They used to be reliable but the DI Turbo engine changed that. Sadly, new vehicles are less reliable than just a few years ago.

2022 Sequoia is the old design with the 5.7L V8. Same design architecture from what they put out in 2008. It’s the ‘23 Sequoias that have the new twin turbo V6 that had turbo issues the day it was launched.
