Hi! Anyone experienced a humming sound from your EC while idling or on a stop. Its a different sound from the AC and the fans. It's like there's a mosquito flying near your ear kind of sound. I checked the sound this morning near my rear tires and it kind of loud from there. Not sure though if its really from there.

Can't say I have heard anything of that kind jancarlo, but will listen out for anything unusual and report back if I notice anything.
Could be that Lunatic59 is on the right lines, that it is connected to the exhaust system in some way.
Only other thought is, could it be the sound of the petrol pump located in the fuel tank that is making its presence felt?

There's not a whole lot going on at the rear of an Eclipse Cross at idle. It can really only be the exhaust or the fuel pump. An exhaust noise would be about the same from both sides and the exhaust pipes follow the center line of the car. The fuel pump would be louder on the side with the tank.

What would be cause if the sound is coming from the fuel pump? I using the car for 9 months and i just heard the sound like 2 days ago. I really hope that its just the heat shield.

A loose heat shield or broken mount is going to be a buzz or a rattle set up by harmonic vibrations of the engine. The fuel pump can be a lot of different noises. If you can consistently get the noise at idle, ask someone to rev the engine a little to see if the noise changes or disappears at higher RPM's. If the noise stay constant at a higher rev, then it's probably the fuel pump. It might be loose in the tank, or a piece debris stuck in it, or even a failed bearing in the electric motor. If you suspect the fuel system, I'd take it to the dealer and let them sort it out.

Thanks! The sound is consistent. I will go and ask dealership to check where the sound is really coming from. I dont like driving unnecessary sound. Its just so annoying. Thanks for the inputs. Really appreciate it!

I have this aerosol release like sound coming from the rear left side, just next to the tyre.
It is the fuel pump!
Nothing abnormal apart from the sound.
Waiting for the new pump to arrive and dealer will replace it under warranry terms.
It will take some time though, with the COVID-19 supply chain disruptions.

I own the car for 1.5 years with 31k km.
Abnormal sound came out after an oil change at the dealer.
The car sat idle in a garage for a month before this occurrence, again because of the virus lock down.

Hmmm.. I think it really is the fuel pump. It is louder at that same spot. Do you always hear that sound every time you drive? I haven't heard the sound for 3 days already. i hope it wont come back.

Hi, jancarlo, When you first heard the noise, what was the fuel level in the tank. I'm just wondering if this would have any bearing on the noise from the pump. It should not really have an effect, but just a thought, that if the fuel level was low or near empty, this might have had an affect and caused the noise from the pump. Good to read the noise has disappeared now, and lets hope it stays away..

Hi! I remember i still have 3/4 in the tank that time. I had a 1/4 tank fuel this morning and luckily there is no sound. I really hope it will stay that way.

thanks! stay safe!
