2023 Tahoe Premier Does Not List DFM on the window sticker

[Z15]

Friend is considering buying one from dealer inventory and looking over the window sticker, no where does is mention Dynamic Fuel Management (DFM) nor does is says Not Equipped with DFM. They seemed to have made a conscious effort to downplay DFM?

AFM/DFM on 2022 Tahoe?

Does anyone know if my 2022 Tahoe has AFM/DFM or was it temporarily deleted from this year due to constraints? The owner's manual has two locations for AFM fuses for the underhood fuse block but the diagram on the actual fuse cover shows no such fuses. The window sticker nor any other...

Ask for a copy of the build sheet...it'll show on there.

This is strange and you’re correct. I looked at 3 window stickers online for the 2023 models and there’s no mention of it. Also, the fuel mileage rating is one MPG less on the 5.3L motor window stickers I was viewing (showing 15 city, 20 highway…my ‘21 shows 16 city, 21 hwy).

Wonder if they gave up on that tech???

I don’t believe the stickers ever listed DFM. Good catch on the MPG difference though….

At the bottom it lists the available engines and says both have DFM

My point was not that they did away with, but that they don't blatantly advertise as they did in the past. Probably because of the bad reputation of DFM engines. According a friend who is in parts at local dealer, they stock all parts to R & R the lifters and its not uncommon for them to see 1 or 2 failures per month. Mine has failed 2x in 21,000 miles. First time, the replaced one bank and the last time they replaced all of them. 5 yrs or 60,000 miles and this truck will get traded in. Anyone would be crazy to buy a GM V8 engine vehicle out of powertrain warranty.

Loving the fact my dealer includes a Lifetime Powertrain Warranty on every new and used vehicle w/ 80k miles on it or less. Its got a lot of exclusions, but it does cover "Internally Lubricated Parts."

It's not that serious and probably has no bearing on why it's not included. 2 a month ? I was doing transmissions all day everyday. Still doesn't mean that most fail. Keep beating the dead horse lol.
