Noise coming from passenger rear speakers on new car

I have a new 2022 Limited with Kenwood factory sound system. I’ve had a noise coming from my passenger rear speakers even with the radio/music off. The noise seems to come on only when I switch on the car lights, or when I hit the brakes (and brake lights are on). Does anyone have any idea what this might be ?

Sounds like ground loop interference. Should be covered by warranty. Take it back and make them fix it.
they wanted me to leave it for a few days for their trial and errors attempts. Which I think is ridiculous. Mine is currently at 210km, so it’s incredibly frustrating.
With electrical issues like this, you're never going to just know the answer by hearing a buzz from a speaker. It will take them time to trace down the wiring and test all the options until they resolve it. Not sure how else you expect them to fix it. That's pretty normal.

This sounds like such a nightmare. I didn’t buy a brand new car so I would spend my time at the dealership! Especially if it’s clearly a manufacturing issue that they should have addressed. I have another appointment there in 2 days and will see how that goes. But this doesn’t sound too promising.
If anything, I think I should be offered a replacement.
I can understand your frustration, but this isn't unusual for a new vehicle to have some kind of issue pop up. That's exactly why a warranty is included. They need a opportunity to make this correct before just handing you a replacement vehicle. This defect should be able to be resolved, but it will take time. They literally have to take 1/4 of your interior apart to trace wiring and test every connection that could be causing the problem.
Well, they've already had the car for a week, and they still can't seem to figure out what the problem is. I call them almost every day, and it's always "we're still trying to figure it out, and we'll share an update tomorrow"
That is when you ask them to escalate the issue, or reach out to corporate for assistance. If they refuse to escalate, then you can for sure play the replace my vehicle card. Sucks that you're dealing with this.
