GM To Offer $50 Credit On Chevy Silverado And GMC Sierra Without AFM/DFM32
General Motors is starting to build light-duty Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks without Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) technologies as a result of the ongoing global microchip shortage. Now, GM Authority has learned that GM will offer a small credit on every impacted vehicle.
In an email exchange with GM Authority, Communications Manager, Chevrolet Trucks and Full-Size SUVs, Megan Soule, confirmed that General Motors will offer a credit of $50 MSRP on every VIN impacted by the change.
As GM Authority covered previously, some 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 models equipped with the naturally aspirated 5.3L V8 L82 gasoline engine and naturally aspirated 5.3L V8 L84 gasoline engine will no longer feature Active Fuel Management and Dynamic Fuel Management due to the ongoing microchip shortage.
Active Fuel Management deactivates half of the engine cylinder banks under light drive conditions, thus improving fuel mileage. Meanwhile, Dynamic Fuel Management also deactivates cylinders for improved fuel economy, with up to 17 different cylinder activation patterns for optimum efficiency and power delivery.
According to GM spokeswoman Michelle Malcho, the omission of AFM and DFM technologies on 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 models is expected to lower fuel economy by about 1 mpg. Malcho added that GM will continue to build light-duty pickups without the fuel-saving tech, but did not specify the volume of vehicles expected to omit AFM and DFM. That said, the change is expected to be in place for the remainder of the 2021 model year.
So far, the microchip shortage has reduced availability of various vehicle options, including those for GM’s popular full-size SUVs. It’s estimated that the shortage will result in nearly 60,000 vehicles to be cut from GM’s North America production schedule.

Wow! I’ll take 10.
$50 credit. GM basically giving the middle finger to their customers. Just imagine, between this and the “sorry your 10 speed truck was made with an 8 $200 credit” you can be saving a total of $250 on your 60k truck!!! WOW!!!
I don’t necessarily think there is anything wrong with DFM, but I think a lot of people would be willing to PAY $50 to get a truck without.
There is a huge problem with the afm system. Failed dod lifter. Get better mileage with a proper tune and disable it. Added cost of the system is not worth the headache and its actually counter productive. You probably wont believe me on the better fuel mileage part but ive/we’ve tuned over a hundred trucks and cars with it and all have increased mileage, more hp and torque. People like to believe engineering data tested in a controlled environment but never test real world applications. And in a real world scenario removing it is better for the vehicle and the customers wallet.
Afm hasn’t been a widespread issue in a long time. Regular lifters fail too but lots of people who blame any engine issues on AFM, ESPECIALLY if they’re selling a product to get rid of it. What you’re not pointing out is that any increase in mileage is from setting it up to run 91 octane which completely wipes any savings, and some. That’s where a lot of the power gain is coming from too, typically lower rpm timing increases (gm is very lazy with this for powertrain protection) and more aggressive shift patterns.
The $50 saved isn’t ditching any of the afm or dfm hardware, just the software to control it.
I still run afm in my 2018 at speeds above 65 and my fuel mileage does increase when it activates.
Damn could be a great time to buy an A10 SS if they cant supply AFM chips for the camaro
This is great news. Maybe I won’t see as many Chevy’s in my shop with collapsed lifters.
Oh gawd. I doubt you are a mechanic and I doubt you see Chevy trucks with gen 5 v8s with problematic afm lifters. Just making stuff up
I actually own the place. I leave the monkey work for blockheads like you. Work smarter not harder.
Don’t believe that GM can’t find the chips for the AFM ,I believe that after so many complaints from GM vehicle owners they decided to eliminate the fixture without admitting that it was creating havoc in the vehicle systems…
Driving the truck to get the most out of the fuel mileage is not on 99% of owners mind. People drive them. Engineers are trying everything to get more fuel mileage. But you can’t change the driver. More and more plastic is being put in them, and more plastic is being put in our landfills. Look at the debri after an accident. Plastic lying everywhere. Give me my truck back!
Yep just had a lifter collapse twice in one month on my 2015 Sierra. Had i known they were going to do this I would have just traded it in for a new one instead of paying for an AFM/DoD delete kit.
The lifter issue is really a non issue anymore. They redesigned the system and there are few failures.
We used to sell tons of retro fit kits but when the redesigned the deal sales declined on the kits.
People would pay more to eliminate the auto stop so they don’t have to hit the button all the time.
Go ahead and delete auto stop/start. No one will miss it either.
Had lifters collapse TWICE within 2 months on my 2015 Silverado Z71 1500 with 5.3. Traded it in on a 2020 with “start/stop” feature that I absolutely hate. Cost me 100 bucks for a “start/stop” delete. Can’t win with these new trucks. Too many federally mandated fuel saving gizmos on today’s vehicles that result in headaches for the customer.
That’s why I’ll stick with my 2002 GMC Sierra.
I won’t buy modern vehicles and I have to actually laugh at people financially stupid enough to buy them.
I would pay $100 not to have AFM.
I deleted it on my 2007. Best thing I ever did!
Awsome. Now ditch the useless ABS too. I’ll go buy a new one.
Most people would have paid MORE to get rid of AFM.
Cool now they will stop having collapsed lifters due to the horrible afm design. There is nothing to gain from cylinder deactivation. Believe me ive done tuned a ton of vehicles with them. Disable cylinder deactivation and give it a proper tune and gain 2-3 mpg just from that and no other modifications. Surprising right? You will actually get better fuel mileage, 20 horsepower, and 30 torque to the wheels with afm disabled and a tune. That is actually the selling point of most of the tunes that ive done and customers are way happier with their vehicle after its all said and done. And thats on the trucks AND the cars. It one of you have a gm truck or car with the Gen IV LS or Gen V LT the first thing you have to do is get a tune with the afm delete and you will no longer have lifter failure.
I would have bought a new Chevrolet truck but the AFM stopped me from buying one. Ive always been a Chevy guy. But i screwed up an bought a stupid F-150. It was a piece of crap from the start. So i ended up buying a 2014 2500hd with the 6.0L im happy so far with it. Chevrolet please go back to the NON AFM MOTORS
50 dollar credit… its going to cost me over 400 to turn it off on my 21 that I just bought because I don’t want it or that auto start stop…
Ditch the ABS…you can pump the brakes that fast? I can’t begin to tell you how many people ABS saves…I say get rid of the fuel management system, start/stop and all the useless air bags… overhead, side, knee, curtian, man how many air bags do we need? Just the keep the driver and passenger. While where at it I want a rubber floor with a vinyl or cloth beach seat, real outside doorhandles you can fit your hand around with gloves on, a back window that opens, no fake plastic vents and grills, just a plain old work truck!
How about I trade them modules? Considering I just paid for an AFM delete module for my Chevy Silverado. I hear nothing but positive reviews for the range technology AFM delete module.
wow $50 what does GM give you for $50 you can’t even get $20 walmart grade mud flaps for $50 from GM.
$50 is ALMOST a tank of fuel 🤣
Had to have new cam and lifters put in and at an after market race shop after the GMC Dealership told me I had a “sctratch” in the cylinder wall” and charged me a $300 for a wrong diagnosis on my 2015 Yukon Denali. Absolutely NO ACCOUNTABILITY BY GMC. My next vehicle will be German!
$50… is that how much the system is worth? Def not doing any favors
I had a stuck lifter in my 2013 suburban. Deleted AFM. ABSOLUTELY worthless in my opinion. Fuel mileage the same. Thousands of class action lawsuits against GM for this issue, yet they sent an issue. Oil consumption is your first clue. $1800 later and no help what so ever from GM, my motor is great. What a shame GM didn’t fix this issue a long time ago. I would have paid $500 to not have it!
