Nada for me. Ive actually never seen any GM truck I have owned get an OTA update lol. Probably will just intro more issues anyway. Give years on the refresh and audio still cuts in and out on the new trucks.

What is the 'Aero shutter system'?

The shutters behind your grill.

I hit decline on the last one. My truck is running good why spoil it.

 

[Byrds8]

Mine cuts out once in a while. Everything else seems fine running wise.

Word!

Can't decline this one.

 

[MO_ZR2]

Can't decline this one.

Last sentence - “There’s also the option to forego the update entirely via the Decline button.”

Only for 2500HDs!

GM Authority must be running short on content. I've had this update installed OTA in my 2024 LZO ZR2 for a few months already. A quick Reddit search shows talk about this update 5 months ago.

Cannot wait to get this one! The shutters on mine froze shut in an ice, sleet and snowstorm last year. Had to go to a car wash in Pecos and use the hot water to melt it all. Threw a check engine light and told me to pull over to prevent over heating lol. No problems after I melted it all off. Was several inches thick!

That's cause you didn't put your grill cover on from under the rear seat and drove right into the storm! We already covered that slick!

Still haven’t seen it pop up for mine. Maybe 2026 don’t count lol.

But you don't want to do that or Mary will get mad

I read somewhere you have 45 days to install the OTA or GM may not cover whatever the update was supposed to fix (or break which is usually the case).

 

[OC ZR2]

Checked for updates and it doesn't come up on my rig. Shutters don't freeze in SoCal

Any excuse not to pay
