I don't know about you guys but is it me or does your civics have this sort of flapping sound. Something like a fan hitting something? I can only hear when I accelerate but I was headed up a mountain during that time. I will definitely record it if it continues.

I'd do a cursory check in the engine bay and under the car to see if you happened to catch some debris on the road which is making that noise. Otherwise take it into the shop and have them look at it. Good luck!

This what it exactly sounds like but mines isn't as loud. It's not even noticeable when I'm listening to music

Mine does sound like the fan noise, I haven't noticed it before. Just installed intake so I have been driving around with no music on. :D

So I also have a friend who has a 2016 Honda EX-T Sedan who apparently bought it around the same time I bought my civic. I asked him if his engine made that fluttering sound and he confirmed it that he had it too, especially when going uphill. He took his car to the dealer and they said it was normal.

My 2016 civic makes a similar sound too, only when I step on the gas pedal. The only way I can describe the sound is when you place a card on a cycle wheel.

It's the valves from the high pressure fuel pump. Normal with turbo setups and with high pressure fuel pumps.

My Touring does not make that sound. At least not that I've heard, and I go up a very steep hill at least twice a day.
