Our Pacifica has had intermittent issues with the stereo intermittently making static sounds. A few days ago it was so doing this when we turned the car off, then it started making a clarinet or bagpipe like sound that we could not stop. It quit on its own when the stereo timed out after one minute. Now when we turn the car on it makes a constant screeching sound that we can sometimes turn down or sometimes have to power off head unit. We have unpaired all devices, pulled everything from USB ports, and tried different media sources. I also pulled all fuses that seemed relevant to Uconnect, media, or radio functions. Has anyone experienced anything similar? If so what was resolution.

It’s anything and nothing. FM, AM, Bluetooth, CarPlay. Or nothing. We have paired and unpaired and pulled all media from USB ports. If the main unit is on and volume is up it is screaming, even if we are not playing anything at all.

Sounds like it’s oscillating.

Could be the amp

Sounds like it’s oscillating.

Maybe I don’t understand the term as used here, but my research on oscillating leads to engine vibrations or similar engine noises. This is coming from speakers and happens when stopped, in motion, on gas, electric mode, or engine off and in accessory mode. Does oscillating refer to something else in this instance?
I finally snagged an appointment at dealership so hopeful for a resolution. I was told the earliest I could get in was over two weeks out but got lucky!

The radio amplifier possibly going into oscillation.
Nothing to do with the driveline.

Ours did this for a while. Then the uconnect died. We took it in and it needed a whole radio module. 7-10 days to get it as it "has to be configured by Sirus. Which I do not use. Still waiting.

what ended up happening? You mentioned taking it to the dealer, what did they say? Mine is doing this now too 🤦🏼‍♀️

We are going through the same situation. Going to call the dealer today. We have a Pacifica 2017, bought brand new and no issues until now.
