2021 Yukon Denali - Auto stop/start - any news on disabling automatically?

[Craignor]

I'll try this out! Maybe the adapter will fit inside the plastic hitch cover as well. Nice.

Please try it out and let us know if it works.

I can confirm that the Range Technology start/stop disabler will not work with the 2021 Yukon. Their site does not list the Yukon under 2021 models, but does list the Sierras. I ordered the 2020 model and called their support line (which is Holley, which owns Range), and was told "it should work".

It doesn't. Full refund, but I hope they get one put together soon. I went ahead with our purchase of a 2021 Yukon with the thought that for sure Range would have a 2021 product that would work. I use the Range cylinder management product on my 2017 Sierra and it's flawless.

I'm a little troubled that you can't get through to anyone at Range using the numbers and email addresses on their site, you have to navigate to Holley. I'm not sure Holley is invested in making Range continue.

Anyone have any luck with this yet?

I can confirm the Duramax does indeed have autostop, Bummer. Anyone have a solution yet?

Also wishing it could be permanently disabled. I have found that it cuts power to the auxiliary plug in the back which causes horrible static sounds in the kids headphones.

BTW, trailer coupler with leds does not disable our Autostop.
(I do not have the Max Trailer Pkg)

Bump - my dad bought a 2021 Tahoe and I'm wondering if there is a fix out in the wild yet.

First of all, the Tech 2 hasn't worked on ANY model since 2013...

GM cannot disable the auto stop because it will affect emissions output. They gave you a button to be able to disable it so you're just going to have to use it. That's the price to pay to still be able to buy a body-on-frame SUV with a big V8. There probably will eventually be something aftermarket to disable it but unless it is like the Range device that just plugs into the DLC port and can be removed at any time it will void your warranty.

You can disable this on the F150 with a $10 FORSCAN cable and <5 min. Certainly, there must be a simple way to disable this for GM products. So much so that GM just announced that they will build Tahoes/Yukon without the start-stop function temporarily because of the chip shortage:

GM to build some pickups, SUVs without Automatic Stop/Start feature during chip shortage

GM will stop offering an automatic stop/start fuel saving technology in some pickups and SUVs due to the ongoing semiconductor chip shortage.

Has anyone seen or tried this? It seems like a great option. Does not remove the feature but remembers The last setting when vehicle is shut off. But it can be turned on if desired. The video on the site shows install on a slt trim and not a denali trim. Works with both gas and duramax
