Fluttering sound! Has anyone had a similar issue?

[Davidsbronco]

I typically have a fluttering sound in the bs every time I drive it. It usually happens at low speeds. Has anyone had this issue? If so, what was the fix?

Can't hear it. All I hear is the road noise.

Air passing over turbo at peak boost

Air passing over turbo at peak boost

So it is completely normal?

Don't have any fluttering noises on mine.

Doesn’t sound normal. Sounds like something is loose? Maybe go underneath and check the plastics.

Are you talking about that sound at the 4 second mark?

Only fluttering I get is when the windows are down and the middle seatbelt starts to flutter. really kind of annoying.

I know the sound and I get it too. I know it's an oddball engine so I'm just kind of rolling with it, so to speak. I'm keeping my ears open for any worsening and then at that point maybe I'll do something about it because I know they're not going to hear anything 'out of the ordinary' at the dealer already and that'll end up being my problem TimeWise.

If noise is coming from interior then it’s probably this.

Hard to tell from video but could be park cable. There’s a few threads on it already. More info in my post here:

Pretty sure you're in the realm of the infamous second most epic forum thread there is.

Although I could not hear it in your video, I am almost certain I know what you are talking about.
Mine does it specifically at low speeds with minimal pressure on the gas pedal. I am almost certain that it is the turbo kicking on and off... there is not enough power demand for the turbo to stay on, but there is just enough for it to keep trying.

The reason I say this is that if I give it more gas the sound will stop and i have normal acceleration sounds, and if I completely let off the gas the sound also stops (and my bronco decelerates). Plus, I can actively cause it to make the fluttering sound if I play with the gas pedal pressure at low speeds.

Count me among those who only hear a car driving down the road with the same typical road noise I hear in every car I've ever been in. I'm not saying you don't have a noise in your car ... just that my ear can't hear anything abnormal in that video.

And I only mention this because maybe you could try again to capture the offending noise and thereby get more specific help ... since lots of the above was speculation based on what you might be hearing (since few can detect anything in the original video).

Hey there. Can you send over a private message with your VIN and the name/location of your local Ford dealer? I would like to look into your engine flutter concerns on my end!
