Hey Guys,

A strange sound I have heard recently when slowing down. It is like a humming sound almost sounding like electricity buzzing. It typically happens 20-40km and to complete stop. Once the cars stopped in neutral no sound happens. Brakes do not have to be pushed to hear this sound. As when i take my foot off the brake to move up slowly and then press the brake again i can hear the sound. It is not the ATF that is completely different.

Anyone else experience this and know what it may be?

Thanks.

I have 2013 Acura TL Special Edition and I happen to notice the same thing in my car as well, when I drove through the parking lot around 20-30mph. the sound came when I let the gas paddle go, it sounded like somebody was using lawn blower at distant.

Didn't paid much attention to it afterwards, cuz I know my OCD would bother me, now that you have mention it makes me want to research on my car as well.

Anyone know or familiar with this sound please help.

engine braking?

Is it maybe similar to this noise? https://soundcloud.com/user531803926/new-forward-3

Thats what my car does, I have a 12 awd. I've found out it seems to do it either only or a lot more when I need gas.

Just to say, the buzzing I hear starts around 7 seconds. The "bumps" are me going over grooves in a parking garage

Yeah that is pretty much the sound. A little bit of music and you dont hear it though haha.
Anyone have an idea what it is?

propeller shaft may be the source of the noise

Isn't that an issue with the AWD?
Mines a FWD. Sorry should have mentioned that.

Yea mine is AWD, so if yours is FWD, then it wouldn't be that. Like I said, I hear it more when I need gas but I am glad someone else in the world is experiencing it

Does yours only happen when you need gas?

Im at a half tank now. And i tried replicating it but could not. I always tend to hear it after leaving the train in the evening after work. I will try to do that then, maybe its when the car is cold. Will let you know.

Yea I'm almost empty and will try to duplicate it tomorrow. What state are you in? I'm in the DC area.

Yep still just under half and not able to duplicate it. It must be when gas is low. Taking her in next week for regular maintenance. Ill inquire about it.

Let me know

Took it in, they said they could not duplicate the sound. Of course they said that. But on a side note they did duplicate the sound for the ATF gurgling and finally have that fixed. So at least im happy about that. Did say the car was in perfect condition though.

Ha yes, that gurgle was the most annoying thing. Took forever for them to believe me that it was the ATF. Now they have a service bulletin for it

Definitely heard the humming sound today again. Sounds like a computer and only ever hear it when slowing down below 20km/h. And my tank is over half full.

damn it! I thought I had the gas thing narrowed down

I seem to notice it more, at least in my car, when the weather is humid.

Bump? Any help with this?

Try shifting into N when you're at that speed. See if the noise is still there. If its gone, then you can rule out the drive train.
Ive had a humming noise at idle and slow speed. Found out while changing the timing belt that the outer belt (ac,alternator ) tensioner pulley bearing was worn to death.

Has anyone figured out what this is? It's driving me insane. For the past few weeks I have noticed the sound (a humming, perfect description was said, "like a leaf blower in the distance" from the front end of the car), thinking it was only inside the car that I could hear it and I rolled down the window and it's even more audible.

Its not gas levels, I have a full tank of gas, and it's not engine temp I don't think because the car was at normal operating temp.

It it happens every time I've been driving above 40mph and then decelerate (to come to a stop sign, for example).

It's killing me softly (and loudly if the window is rolled down). HELP!

for those who has this humming sound is it coming on the right side (air filter housing)? Mine seems to be coming around that area.

I think it may be coming from the right side, yes. I'm wondering what around that area would cause that odd humming noise...

My sound is gone, that sound was from my failing alternator. Sadly mine failed at 148,709 KM while I was on my way to my shop to get it replaced. Car just stalled all kinds of warning popped up and on top driving on highway. With no power this electric steering was heavy turning but safely no one was behind me and I was able to pull over on right even the brakes were hard to press.

I am surprised my alternator failed that early.

Are you sure it was your alternator? What would cause it to make that sort of noise as it fails? And how long was it making that sound before it died?

I hate the idea of having to replace that. Was it expensive?

Yes, battery wasn't charging and I got Check Charging System. At the dealer they quote $1500 CDN but I did it from small shop iGarage at $580 installed.

My 2014 TL FWD 55k miles just started making this Noise & it’s driving me crazy
it only does it when off the gas slowing down around 10-15mph & it’s not every time
