I recently purchased a 2026 Honda Passport and have been experiencing a persistent fluttering noise whenever the air conditioning is running. The sound occurs whether the vehicle is stationary or in motion and disappears when the A/C is turned off. I brought this issue to my dealership’s attention, but they advised me that the noise is “normal.” However, it’s distracting and detracts from the driving experience.

I would appreciate it if you could clarify whether this issue is known, if there are any technical service bulletins related to it, and what steps I can take to resolve it.
