Thanks for the suggestion. I’ll check it today when I get home.Check your interior cabin air filter behind the glove box to see if it’s seated properly and also get your head down in the passenger foot area and see if the blower motor is making that noise.
Check tranny fluid level. Most of these vehicles come from factory with fluid level barely in safety range! Just like your antifreeze is barely above the min mark. Only thing I can think of is they can save money on fluids to barely in the safe range. Just a thought. Good Luck!!I have a 2018 Touring and mine does this as well. You can actually hear it outside the vehicle while it is running. It seems more noticeable when its colder, but still makes the noise consistently. It seems to be coming from the Drivers side front area. Honda had it for 2 hours and said they found nothing, and of course when we drove it with the service guy it didn't make the noise.
Finally, they have a TSB for this issue. I had the sound on my wife Pilot 2019 EX-L and they had to change the driver side motor mount. I still here the noise and I am planning on taking it again to check the other side.There is a TSB for noisy rear engine mounts causing a chirp at idle in Drive.
