2025 Heritage 2.7

Hi all,

2025 bronco Heritage - 2.7 1200 miles

Yesterday I went on a 200 mile drive round trip and noticed a whirring sound coming from what appeared to be directly in front of me behind the fire wall and in the engine bay.

The sound was definitely louder at highway speeds and only occurred when I would put any amount of pressure on the gas pedal. As soon as I let off, no matter the speed I was driving, the sound went away. As soon as I tap the gas again to begin accelerating, sound is back until I let off the gas again.

towards the end of the trip, I was more in tune with this sound being present and also noticed it even at lower speeds when going from stoplight to stoplight util I made it home.

I’ll be scheduling a service appointment but curious if anyone has any insight here.

Late Edit: Front differential had a bad/defective seal and was leaking, thus causing the whirring sound. Dealer repaired.

Have you driven a vehicle with turbos before?

Sounds very much like you could just be hearing the turbos spin up.

I knew I should have edited the post to include the answer to this! Yes, I’ve had quite a few turbod vehicles before. It’s most definitely not the wind up of the turbine. This sound happens before there’s even any amount of boost.

This is not the best video at all but if you listen very closely, you’ll hear this very subtle whirring sound. You’ll hear the turbo as well. In the video I was hitting the gas for a bit and then letting off completely. When doing this while inside the car it’s much more noticeable of the sound.

had to shorten the video because on mobile it won’t let me post the full 1 min. You’ll hear the sound start right at about 8 seconds in and throughout the rest of the clip.

Appreciate your input man.

Anyone have any ideas?

I'm scheduled with the dealership tomorrow and will keep you all posted once they figure it out. I've scoured Google and wasn't able to locate someone with a similar issue that posted about it.

Try turning the climate control completely on and off while it is making the noise. Might be a stretch, but I had a car with a bad wheel on the AC compressor which made some crazy sounds.

You can check your Fordpass app on the Service side and see if there are any vehicle health alerts for thrown codes. You might also find a recall notice there for Child Safety Locks.

Since it’s happening under throttle, might be worth checking your intake tubing and be sure all those connections are securely clamped.

Good luck at the dealer!

Appreciate the reply! I did test this at both highway speeds and stoplight traffic and the sound was unaffected.

Thanks for the reply! I tend to forget about the Fordpass app as a resource, I will look into this!
