Hi
I seem to have a chirping noise in the cabin once the car has been driven around for a bit. The dealer changed the fuel pump first thinking it was related to that, but the noise was back. By then I figured out that if I turned the HVAC off, the noise goes away - with this information, the dealership changed the blower motor but the sound is still there. Has anyone else experienced this and what are your suggestions? It's not always possible for the sound to be reproduced at the dealership which makes it hard. In the attached video, the noise can be heard and once I turn the HVAC off it goes away.

My 2017 MDX Tech has the exact same issue too. I noticed that it started happening one day after I floored the car from a stop. I'm not sure what caused it, but i've found that if you put the fan speed to 3 or higher that you wont be able to hear it as much.

So on one of the other forums, someone suggested that it may be linked to the rear blower motor and advised me to turn off the rear HVAC and notice it. I tried it this morning and lo and behold it actually disappeared with just the rear HVAC off and front still on. It kinds of makes sense as the sound seems to come from the center console area and that's where the rear motor is located. I now need to get my dealer to fix it.

Oh interesting, I never thought of turning off the rear A/C. Well that solves that I suppose. As for getting the dealer to fix it, are they doing in by goodwill or do they charge you for it? I'll have to look into getting it repaired aswell.

I have extended warranty so they are covering it through that, also I took the chirping issue to them when I had comprehensive warranty and they changed the fuel pump, so they know the issue was opened before my warranty expired and have been great so far. I just spoke to the dealer and told him my findings and he's going to come back to me with when he can replace the rear motor. Your 2017 should still be under warranty and should be covered.

Oh I see, thats good to have I suppose. Our MDX is currently at 64k miles so i'm a decent bit past the warranty period. I'll probably just let it be for now as its a minor inconvenience at most. Thanks for the info though!
