Is there any truth to the below:

2026 Silverado owners found a reliability top priority: the 8th VIN digit "E" confirms the 5.3L V8 lacks DFM hardware. This factory delete solves the notorious lifter failure issue plaguing Chevy trucks since 2019?

Can anyone tell which trim are these trucks and where can I find a new 2026 with this fix?

No engine digit "E" for 2019-2026.  Stop reading slop online

 

 

All 2026 V8s have functioning DFM.  Hardware and software.  5.3 and 6.2.  The L84 5.3 has "D" as the 8th digit of the VIN, the L87 6.2 has "L" as the 8th digit of the VIN.  

 

 

If you want a factory DFM disabled 2019-2026, you'd have to find a used 2021 or 2022 chip shortage truck.  The vehicle build data will have a specific RPO code indicating its a factory disabled truck.  RPO code YK9 and only with the L84 5.3 engine.  These still have the hardware installed but are NOT functioning due to the COVID chip shortages that were ongoing.

Thanks New Dude'

I got my information from Torque News

2026 Silverado VIN Hack: Look for 8th Digit ‘E’ to Confirm the DFM-Free 5.3L V8 That Ends Lifter Failure

 

Can you tell me if a new gasser GMC 6.2L Denali or a 2026 5.3L Denali is safe to purchase? I have read a lot about engine failures and just want to be safe. What would you recommend? Plan on purchasing a new truck in the near future.

Thanks for your assistance,

John

That article is complete BS.

 

Get the 5.3 over the 6.2.  Or, wait for the new trucks.

He proves his stupidity even further here - 2026 Chevy Silverado Owner Scans VIN and Finds A ‘Holy Grail’ Discovery; He Says, “GM Officially Deleted DFM Because They Knew The Lifter Issues Were Killing The Brand”

 

The VIN in that article 1GCUKGED7TZ191335.  The 8th digit is literally a "D".  1GCUKGED7TZ191335

 

1st - 1

2nd - G

3rd - C

4th - U

5th - K

5th - G

7th - E

8th - D

 

D is for the L84 5.3 with DFM.  The build sheet of his "smoking gun" VIN shows L84 5.3 with DFM.  What a r'tard that person is.  He even sites an AI SLOP video on YouTube as a source.

Thank you very much for this info. I will start looking for a 5.3L. I have viewed several Youtube video and get so confuse. You are the first person to give good advice. 

Thanks again,

John

      AFM Experience

      By KARNUT · Posted

      The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda.

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
