Active Noise Cancellation? Not installed in Yukons

[Edavis5300]

We’re having issues with strange pressure in the cabin from our 2024 Yukon 3.0 diesel.

We thought it could be ANC, but our dealer is saying our Yukon doesn’t have it whatsoever.

Is this correct?

rpo code uqa has anc
noise does not create "pressure" though, perhaps sound pressure of some sort, if you want to see if it is the radio, pull the radio fuse and take a drive

Thanks for the reply!

When trying to trouble shoot why I would get an odd tone in my ears when just sitting in the car, I thought the ANC could be overbearing.. But the dealer said my Yukon didn’t have at all.

I’ll try to unplug the amp all together and see how it goes on a drive.

Seems we will be getting nowhere for a solution from the dealer.

Edit: Here's what I found for the RPO code, is the ANC built in to this?

UQA	Audio system feature, Bose premium 8-speaker system

well apparently on a 2nd look uqa does not indicate that it for sure has anc
On my 2012 I know it has ANC because there are microphones in the headliner
not sure if they still put them in the headliner in the t2's or not, but if you look right above your head in the drivers seat and see at least 2 little grills and atleast 1 little grill above the front passenger side then it likely has anc, if you only have 1 grill above the driver then that is just the environmental temp sensor.
a rear passenger side grill is also just a environmental sensor

according to the overlords the anc mic on the newer trucks is......
The microphone for the active noise control (ANC) in a 2014–2022 GM, GMC, Cadillac, or Buick vehicle with a Bose or non-Bose amplifier with ANC is located in the rear headliner. The microphones above the driver and passenger seats are for Bluetooth

 

[Doubeleive]

maybe someone else with a T2 that knows they have anc for sure can verify the locations

My Yukon only has a mic next to each sun visors, and not above the 2nd row passenger seat area like our 2015 did.
