Hey friends -- I'm getting ready to pull the trigger on a 23 Sierra SLT (5.3 motor) but some of the known engine problems are making me nervous.  Does anyone have insight as to what percentage of the 5.3 engines will end up in the shop with premature lifter failure?

Out of the total production of vehicles, only a small percentage of us ever join an online forum, an even smaller percentage of us on forums experience lifter failure. Guess who posts online more abou

They all have DFM.  GM no longer mentions it on the window stickers but they make no 5.3L or 6.2L engines in the truck w/o it.   Some it may come disabled but all the components exist in the engine, j

I didn't give it a 2nd thought. There are probably 100's of thousands of trucks out there that have never had a problem. If it happens, it happens. Then I'll deal with it. Sure not losing sleep...

Guess who posts online more about lifters. People who are posting about how their lifters are going strong? OR People who have experienced lifter failure? People who post about lifter failure are a very loud super small minority. The likelihood a vehicle you purchase has lifter failure in its lifetime due to DFM/DOD is infinitesimally small and I have never let it deter me from purchasing any of my 5 2015+ GM vehicles.

Will it use oil, transmission clunk, rear window leak etc.

DFM is the contributing factor to lifter failures.  Check if the 5.3 has DFM.  I ordered My 2022 in Dec. of 2021, got it in March of 2022 and it didn't have DFM. Doesn't sound like a helicopter with performance exhaust.

I would not worry about this issue at all. IMHO GM makes the best pickup trucks in the world. I have been driving Chevy and GMC trucks for over 30 years. All brands have some issues or failures (including motorcycles). I would go ahead and order the new GMC. Disable the DFM when you take delivery.

The DFM cannot be disabled. Disabling DFM will void the power-train warranty.

It's all back now. You just got one of them during the chip shortage.

You got a truck without DFM software/hardware installed. You still have an engine with all the DFM components, including the DFM lifters.

Correct, but I think the lifter problem comes from DFM activations.  I've kept up with other lifter threads and haven't heard of any failures from one that has DFM deactivated;  yet that is.

...Is your opinion.  There is no collaborative evidence that lines up with that - Bad lifter springs and lifters have failed in engines with and without DFM, those parts are the contributing factor, not DFM.  But, your popular yet unproven opinion sells lots of Pulsars and gives false security to those of you seeking out trucks that shipped without the DFM chip.

You’re asking equipment to do more. Adding more parts to make it happen. Requiring more maintenance to keep it happy. So naturally raising the odds for failure. That’s the facts jack. It doesn’t take much research to find those facts.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
