picture is bad quality but that was what it was. They replaced the lifters but I give them credit, it only took a couple days.

Just started having this same issue in my 2021 RST (5.3l V8) bought in March of this year. Started running rough and misfiring yesterday on the way home. Could hear the knocking in the engine (thinking it was a stuck lifter or valve issue). The knock/tick increases in speed as the RPMs go up (and coasting with no gas pedal input stops the ticking). Parked it in front of the garage and checked the oil. It's due for a change (14% oil life left at about 6,500 miles, so first change). Oil is dirty and dark, as expected, but nothing that should be super sludgy. Turned it on today and engine is still running rough. After idling for about a minute, I got the Service Parking Brake and Service ESC messages with the traction control light. Calling dealer tomorrow.

Mine has done this several times. Service ESC, Parking brake, and traction control I think. Then the transmission shifts funny. If I turn the truck off and on again it will go away. Don’t have much faith in my local dealer so I haven’t brought it in yet. 

This is exactly what just happened to my truck (2020 trail boss) took it to dealership they said they will look at it on Monday, hope the problem can be found and fixed. Downshifts horribly 12000 miles

Following. Just had to tow my 2021 Sierra 1500 SLT with the 6.2 into the dealer as well. Stopped and filled up with fuel and on the way to work it started to misfire and shifting hard. Stopped at another gas station along the way and parked it and had a buddy that I work with come pick me up. Returned after work to haul it into the dealer and went to start it to put it on my buddy's trailer, it started running real rough with the check engine light, service parking brake light, and check ECS light all on. Started second guessing the fuel and everything but had my receipt that said I had got premium fuel and not diesel. Truck has 10k miles on it and looks terrible being pulled into a dealer by a Ford.....LMAO

Welcome to the site.

 

By your description of how the engine is running, my guess would be an internal failure, lifters, bent/broken push rod as possibilities.

Really don't even want to read all of these different threads on the same lifter issue anymore at all.  So disappointed in this truck now.  Should have stayed in my old one.

I got one of these. and it works great. It turns off the cylinder deactivation. https://www.edgeproducts.com/products/in-line_chips_and_modules/pulsar/pulsar_lt/parts/22451                                                                                                                               The truck runs better, no more auto shut off and I think I picked up some mileage.

This is exactly what just happened to me today. I have already had injector #4 replaced because of this 3 weeks ago.

This sounds like a common problem and doesn’t sound like they have a fix for it. Im starting to get worried.

My 2021 Sierra 1500 AT4 with 24000 miles, today the service ESC and parking brake screen came on. Cab started shaking if I drove above 45 mph. Steering screen on truck said to be careful.  I was pulling a trailer at the time. Was wondering if the light hook up from trailer to truck might have messed with trucks computer system.

I have a 2020 Silverado LTZ 6.2L with 4500 miles and after slowing down and accelerating again I noticed it was running very rough and seemed to be missing.  The Service ESC first came up and then the check engine light came on.  Shorty after the wrench and parking brake light came on, and I also noticed the whole time the traction control ight was illuminated.  Then the error message went to service parking brake.  This is some BS.  Will update when and if I get a resolution.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍

      primary drive belt tensioner

      By Bill Lemmond · Posted

      2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Atlas · Posted

      +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...
