I've seen one or two folks mention this still being an issue with 2022 trucks and/or the ZR2. Any current owners out there experiencing any lifter drama or sounds leading up to that drama? I got lucky with my 2014 2WT having zero issues and 2019 RST having only minor electronic bugs but I'd be lying if I said I wasn't worried paying $80k for a truck with that kind of dependability issue still looming. Having minor bugs is one thing but what I've seen (consistently) with these lifter issues leaves folks stranded on freeways/interstates hundreds of miles from home, etc. with catastrophic failure of their engine as well as weeks in the shop. HOPEFULLY I get tons of responses telling me those lifter issues are done and over with and not to worry about my ZR2 on order. 🤞

The lifters have been a problem since 2007 and GM hasn't changed the design at all since then(when cylinder deactivation started). They don't normally fail until they get a bunch of miles on them though.

It's been a while since I've seen a relatively new 5.3 or 6.2 have a lifter failure. What happened back in 2020-2021 was a bad batch of lifters from the supplier. There were a lot of factors that cause this but you can pretty much blame the disaster that was Covid and the production problems that it caused back then.

I have a 2021 Trail Boss with a 6.2L that was built right at the tail end of the timeframe when it could have issues. So far, 15k+ miles with no issues(knocks on wood).

My 2009 with its lifter eating AFM 5.3 made it 165k with not a single engine related problem.

The lifter supplier issue is over.

I’m a firm believer in you get out what you put in. Impeccable routine maintenance.

Service ahead of schedule, use quality oil. Coolant flushes, diff fluid changes, transmission fluid.

This truck had its oil swapped at 1k with M1EP and will receive the same every 5k as long as it’s mine. (No oil plug, use what you like)

That’s the secret. Cheap insurance.

My 21 TB 6.2L I traded in for my ZR2 had lifter failure at 10-11k miles

well since i've got about 5K miles and I'm currently 500 miles from home, I think I'll follow this thread... :unsure:

No idea. I wouldn't want it disabled. The 6.2 already sucks with fuel mileage. At least DFM helps. It's a misconception that disabling it will prolong the lifters.
With an aftermarket exhaust the sound isn't great when DFM is active. I would like to see real world MPG difference with/without it

I'll say, I am new to GM, but from what I have seen, this lifter "issue" is way blown out of proportion across the interwebs. Even then, it seems the 5.3s have more issues than the 6.2s. I'm sure there will be issues eventually, just not as many as some people make it out to be.
