Jacksknight Report post Posted May 9, 2019 (edited) Hey all, I have this odd buzzing noise coming from under the hood. This is my first hybrid so it may be perfectly normal, but i was wondering if anyone can tell me what it is? It seems to be coming from the passenger side around the wheel well, sorta sounds like a cooling fan is dragging the housing or something. I am linking a video so you can hear it, i moved the camera around so maybe you can get an idea where its coming from. I guess i should mention that it doesn't seem to do it all the time. Thanks all!

lolder Report post Posted May 9, 2019 It may be a noisy electric vacuum pump put that should only be on for about 10 seconds. Quote Share this post Link to post Share on other sites

The AC is noisy anyway so if it's not that, turning it off will help to better isolate whatever it is.

Texasota Report post Posted May 10, 2019 (edited) It may be a noisy electric vacuum pump put that should only be on for about 10 seconds.I think that is likely the sound also. I hear it in the garage after the car is parked but it runs for a lot longer than 10 seconds on mine. It might be up to half an hour. Note that on mine that buzz seems to be coming from the rear of the car as opposed to under the hood. Edited May 10, 2019 by Texasota Quote Share this post Link to post Share on other sites

It doesn't do it all the time though, it will stop after the car seems to warm up. Any fix for it or just part of owning a fusion hybrid? Thanks for the replies, sorry i haven't replied in a bit.

mwr Report post Posted June 11, 2019 just part of owning a fusion hybrid?.I don't hear such a noise with my 2015 FFH. Quote Share this post Link to post Share on other sites
aschulz261 Report post Posted June 11, 2019 It is going to sound like an airplane taking off when you turn the AC on. Because it's a variable compressor, the noise dies down A LOT after it has been running for a few minutes. Quote Share this post Link to post Share on other sites
