Man I just want you to know I love to see content on the Zr2, the offroad videos are the best. It's the whole reason I came to this channel. I don't mind it if you sell the Silverado, the taco seems pretty cool, but I would love to see another Colorado Zr2 in the future, maybe the bison?

Hopefully GM can warranty it. If they do, let's hope they don't find your channel and say you're at fault for the issue because of what the truck has been through lol.

I’m great full that all of my 6.2s have not had these issues. Currently have 2 have had at least 8 other 6.2s with no issues. I have read about the lifter issues. Goodluck.

The new 6.2 has DFM (Dynamic Fuel Management) lifters. They are controlled by the VLOM (valve lifter oil manifold). The old AFM system allowed the vehicle to switch from v8 to v4 mode when proper conditions allowed it to do so. The new DFM system allows the vehicle to operate with whatever combination the ECM deems most efficient and necessary. Whether thats V8, V7, V6.. all the way down to 1 cylinder firing. The issue with these systems, new and old, is that GM is sourcing very cheap components to facilitate the operation of these very complex and advanced systems. I'm surprised there has not been a lawsuit filed.

Got treated the same way with my 2016 Z71 Silverado. I got the 8 speed transmission and it decides to shift really hard at random times. Because the truck drives down the road, GM refused to fix it under warranty. At 80k miles now and just waiting for the trans to go out. Just paid off the truck this year.

Never was a Chevy person until November 2020 when traded a new piece of junk 2020 Explorer Limited for a new 2020 Silverado 1500 RST Z-71 Black 5.3 and I love it. I have an assigned work vehicle so don’t drive it every day and we just got back from beach last Friday and now it has 14,000 plus miles on it. Had second service done at 10,000 miles at dealership and at 10,300 it dropped a lifted. Still would start and run but missed a lot. Tow and repair completely covered under warranty and they had it done within a week including weekend. Had it repaired same day parts came in and they replaced entire bank where lifter problems was. Even with that issue I still love my truck.

You're awesome. I've been watching your videos for a long time

Great video as always Bobby! Sucks the Silverado ZR2 is down but hopefully it will be resolved. I do think if you do plan to sell the ZR2 maybe a bison would be cool like u said, but with the baby duramax it would be even cooler. RIP!

Wow, Rip Zr2. I got a 21 trailboss with 20,000 miles no issues yet, knock on wood. Beautiful truck by the way. When it gets fixed it will be Beautiful again.

Dang, that really sucks bud. It's most likely the AFM system malfunctioning, that's pretty common on the 6.2L so I'd expect a couple of lifters be replaced along with a rocker or two. Might also have them look into the fuel injectors, those have also shown to be problematic in these engines. Best of luck to ya bud. Hope to see the ZR2 back on the channel soon.

Fun fact Chevy says since 2012 98% of its trucks are still on the road to this day they are just waiting for tow trucks 🛻 😂

that 6.2 has been having the lifter issue for years now, i thought they fixed it in early 2021 and were using the upgraded parts. Glad i went with the 5.3 in my Trail Boss. Too bad they don't put the duramax in that ZR2. Love the content man, was waiting for someone to get the ZR2 since i really wanted one but didn't want the price tag, hence the trail boss.

Rip zr2 , let’s see what this Toyota has going manual or not , SEND IT

Idk why cars can be so strange, my grandpa has owned chevys and gms all his life pretty much and they’ve been reliable as hell, so it’s just kind of a one of one thing for your zr2 Silverado breaking down

There is a class action suit over the afm/dod issues on GM trucks. Most of the issues are with the 6.2L but the 5.3L has had issues as well. The newer AFM system seems to be more troublesome the the older DOD system. RAM runs a very similar system on their trucks also with most problems with the 5.7L hemi. The TRX doesn't use the system. Hope it is an easy, quick fix for you.

It just happened to me when I was exiting off an interstate coasting down hill, maybe 35mph. Left me stranded too, couldn't even put it in neutral to move out of traffic. Towed to dealer and was told engine needs replaced. Blamed me for following manufacturer recommended service program. I was told I need to service it every 5k miles not the 7.5k MyChevy App, the dealer and chevy says. So a little dirty oil locked up the motor? Head mechanic said not to worry, his mechanic takes care of this all the time. Why didn't the sales person tell me that? I just rolled 20k miles on my 10 month old 2023 Silverado zr2. Should've gotten the Toyota or Ford. I'm not feeling confident about this $70k+ chevy truck. My first chevy truck. Ugh, should've listened to friends and avoided GM.

We had a 17 Silverado 5.3L with around 100,000km (62,000mi) and coming home one day the engine light started flashing so we pull over, turned it off the on again, code went away, normal operation so we got it to the Chevy dealer and when this happened we had it 8 months...so we got it looked at and it was saying multiple cylinder misfire, ALL the tests they did came back normal, so had to fork out 700 bucks for that, 3 weeks later...same issue!!!!! So I got it towed to another dealer and this time it was saying that the multiple cylinder misfire was double from before so they did more testing and....yet again another 500 bucks for nothing...so we had the truck for just under 2 years and traded it for a 21 Classic Ram 5.7 brand new and got 5k more than what we paid for the Silverado

RIP the 6.2. I feel like it can’t be super serious. The dod/afm stuff has been around a bit. I know gm does change things very slowly, but I thought that stuff was figured out in the gen 4 small blocks. It seems like it’s not even attempting to turn on to the run position, key on engine off. Did they tell you how many control units are missing. I remember you saying that you had no heating steering because there were components not installed do to the semiconductor shortage.

Dod/afm has been an issue since they introduced it and still to this day. It’s a junk system that kills what used to be very reliable motors that got the same if not better at times fuel economy. They had a huge lawsuit against them over it and somehow won even though it’s such a massive common issue.

Got a 2022 Trailboss with the 6.2, 6500 miles on it, love it, but getting nervous. Have a friend with a 2019, he's had no issues.

I love the look of Chevy trucks. I just can't get passed the lack of quality in modern GM vehicles. I know soooo many people with Chevy Trucks and many with Cadillacs that have all sorts of problems. I went with a 2021 Tundra TRD Pro. It doesn't have the tech you'd like to see but I have yet to have a single issue with it.

Honestly I don’t know about modern day Chevy anymore, I would say 2000s Chevys were pretty reliable, my dad had a 2005 suburban, started having (small) issues, nothing major but it was just starting to get pretty expensive (at least I believe it was getting expensive) around 200k-250k miles, we traded it in for a Kia Sorento, it been pretty good the past like 2-3 years

Frustrating, to say the least. I had a similar experience - I bought a new Ford F-150 with the V-6 Ecoboost engine a few years ago. Under 20k miles, the engine started billowing thick, white/blueish smoke from the tailpipe, accompanied by a metal on metal grinding sound in the engine when I accelerated. Read online that many were seeing the same issues. I didn't even try to resolve or investigate further, I took it straight to the dealer and traded it for a Toyota. I'd driven Toyotas my entire life, had decided to try one of these F-150's I'd heard so much about over the years because the mpg on the Ford ecoboost was so much better than Tundra. And the thing was a piece of junk. It's ridiculous to spend that much money on a vehicle and have problems right out the gate. The Tundra is awful on mpg, and the Tacoma is a bit small, but they just run. Chevy, Ford, GMC, all have some good looking trucks but I don't trust them to make a reliable product.

I'm not a chevy guy, but people talk shit about ford all the time. I've NEVER been left on the side of the road in my car. Now it doesn't have A/C right now because the compressor won't... well.. compress air, but it's still going, and the only thing's i've replaced on it before 100k were the alternator and water pump. things that commonly go out on all cars. A/C Compressors are common to go out as well, but that's all cars as well. I would hope they warranty the engine because it's clearly a warranty issue, maybe the computer, maybe a chewed wire somewhere, who knows until it's diagnosed. Hopefully it's not too bad and it can be brought back asap. It would be neat to see a supercharged truck since chevy is very unlikely to even do one... they'd have to maybe put the ZL1 supercharger on the truck I think (still same engine... should fit right?!). Anyway, I would maybe look for an older chevy truck to beat on, I think lots of people enjoy those kinds of projects too.

same this happened to the youtuber lmfscrew with his 6.2 trail boss. it’s a common thing. gm will fix it for free as well, then you gotta get a module to turn off all the cylinder shut off stuff

My GMC Denali 2022 (new body) with the 6.2L also had the same issue. Truck is currently in the dealership.

This is why I have always been hesitant to buy new and it's hard to find trust worthy mechanics let alone an honest dealership or a company who stands behind their products

Some of these technological advances with performance are great, but sometimes, good ol points ignition and a carburetor just seem so much simpler to deal with 😂

RIP! IF you decide to keep it, best upgrade before adding a blower, is to delete the AFM lifters. There's a kit, which I dealt with the older version when I had an 09 G8 GT.. Kia does the same thing as far as waiting till the car is fully broke before fixing it. I had a 12' Optima which was known for engine problems so Kia extended the warranty for the engine. Did all the recalls, which showed the engine had problems, they wouldn't do anything, then on the hottest freakin summer day on the way to work... My engine blew leaving me on the side of the road for damn near 5hrs!! Kia did put me in a rental and put a new long block in, but a shame they wait till the engine blows. Chevy should fix it without any issue, especially since this is a well known problem. Interested to see what the actual issue is and what Chevy does..

thank you for making this video made me make up my mind im not buying a new chevy

It’s most likely the AFM system (Active Fuel Management) the lifters in the cylinders that shut off while cruising may not have good oil flow, ultimately causing their downfall quite literally. They collapse and get stuck in off position and it puts the engine in limp mode after the computer registers a misfire. Sadly this has been happening for almost 15 years I think since they released these motors.
