Lifter issues resolved?

[clg82]

Hello everyone I know I know, there are hundreds of threads here regarding lifter problems. I just purchased a new 2023 TB, and was curious if the lifter issues were addressed for the 2023 model year, with all of the known lifter issues in the past. Didn't know and after searching if there was any data out there to support this yet. Thanks for any help!

I read there is still an issue. Take that with a grain of salt though. I did a lot of research and only know what I read about it online. You can’t believe everything you read online. I just didn’t want to risk it. That’s what pushed me to the diesel.

It's important to note that there are two different "lifter issues". The one you hear about the most is the defective lifters from the early '21 models. Those affected a lot of trucks, and those are the ones that are pretty much guaranteed to break - generally within the first 20k miles. But that problem has been resolved. The second issue does not appear to be resolvable. It's the same one that has existed since the dawn of collapsible lifters, and that is simply the fact that more complicated designs are more failure prone. But this issue is not remotely as widespread as these and other forums would have you believe. I had a 2010 with the same lifters and put over 200k miles on it with no problems. My dad has a 2008 with almost 200k with no problems. Between my friends and family there are a total of 7 AFM-equipped trucks with over 100k miles on them with no lifter issues. You'll find plenty of guys on this and other Silverado/Sierra forums with 100k+ on the T1 trucks with no issues.

Bottom line is this - it can happen. Unfortunately the days of the bulletproof V8 are over. As soon as we started crippling these engines with fuel-efficiency gimmicks it was only a matter of time. Before I decided on my '21 I looked thoroughly into all the options - and what it comes down to is you must choose between either lifter issues or turbo issues if you want a new truck. So pick what you like and extend the powertrain warranty. It's the automakers that decided to saddle us all with this crap so lets keep it their problem and not ours.

I'm thinking about getting a 6.2.....this may be a wild thing to do, but has anyone just bought the truck and immediately put a new cam and lifter set up in? Like maybe a bigger/better cam and lifter kit, get it tuned and roll with it?

I have a 2020 TB with the 6.2. Have almost 28,000 miles and runs great. I always think will my lifters go, or did I get lucky. I do run the Pulsar LT.

Is this problem only associated with the 6.2L or is it the same for the 5.3? Curious and concerned.

Both engines use the same lifters so really there should be no difference. Anecdotally, the dealers in my area insist that it happens a lot more to the 6.2s. I don't know if there's actually something to that - maybe because they output more power, maybe because they attract owners that push them harder - or if it's just all speculation based on what things "seem" like. Theoretically though, there's no obvious reason that it would happen more on one particular engine.

Just wanted to post this video. I have followed this guy when I had my previous truck. He is usually pretty spot on. His example is not a Trail Boss, but it is basically the same animal with GM skin.

My lifters just went on my 2019 this weekend, just under 81k miles. I had the extended warranty till 75k, should have made it the 100k. So that’s my advice…. Get the extended till at least 100k. Or more if you plan on running the truck long. Other than that, my truck has been great to me.

I wonder what GM will do with busted lifter vehicles with expired power train warranties?

 

[BorakTrailBoss19]

I’ll be sure to let everyone know here.

Umm nothing? This is nothing new. My advice as a GM tech is just get an extended warranty like I did on my truck. Also change your oil around 4k miles.

Great advice from a Pro! Extended warranties are not all the same. I just read some horror stories about the Car Shield warranty. They make the customer pay for labor required to prove component failure, even with known problems. This could amount to thousands of dollars out of pocket for an engine tear down and confirmation. Caveat Emptor my friends.

The lifters on my 2019 just went out on Friday the 2nd of February I am at 88k miles and some change. Thank god my warranty goes up to 103k miles because of GM certified Pre owned. so in 3 to 4 weeks I was told to expected it back. I hope you have good luck getting yours repaired in a timely and painless manner.

I have a ‘22 6.2 refresh with 18k now. No issues other than a few minor electronics gremlins (although I swear the engine smells like hot coolant after driving as of late), but every time I turn around I see horror stories about lifter issues - one ‘24 today with 800 miles.
If it’s truly that common of a problem, why would’t NHTSA have pushed for a recall?
