So I have a 12 AWD advance. I've already had the propellor shaft replaced once and the noise I had with that was at highway speeds and it sounded like white noise inside the car.

This noise is different and I can't describe it well so I had a hard time searching. Basically its happened twice in the past week. I've had my windows cracked and was driving next to a solid object (like a wall or car where the sound would resonate) and it sounded like an old GMC truck power steering whine. This morning when it happened, I had driven the car for 25 minutes, so I don't think its a "cold" factor. The only other noise I can compare it to, is if you're driving next some people trimming a tree and your windows are up, that whine that would echo in the car, is what I'm hearing.

The other time I heard it I was going through a drive-thru. But like I said, I've only heard this a few times, I can't figure out how else to describe the noise, it seems to be more towards the right side of the car but I could be wrong.

I called the dealership to see if they were aware of any issues that sound like this and they said it sounds like something with the differential or the tranny but without duplicating the noise, they can't be sure.

SO i'm trying to see if anyone knows of any possibilities, or things to try, I can't figure out how to duplicate it.

I actually like the whine that is coming from the passenger side .

SlyAccord

Wait are you being sarcastic or do you have the whine too? I can't figure out how to duplicate it

I had a similar noise on my MDX. It was the power steering pump. Dealer replaced it under warranty as there was also a tsb on it.

My TL is only 40K miles and has the same whining noise. It sounded like it's from the passenger side and getting louder by day but it doesn't affect the driving condition. Not sure what it is but will drop it at the dealer to check that out.

I was able to get it recorded.

The first clip "Forward" has the whine while in a parking garage at 2seconds-4seconds.
The second clip is another whine again through a parking garage. You can hear it at 7seconds-14seconds (I think this is best example).
The last clip from 1:30 to 2:00 switching back and forth between drive and reverse and it makes a quick whine, so I'm thinking its the transmission??

Man that was a really weird noise. The noise I've heard on my car wasn't like that, it's more like a consistent whining noise. At first, i thought it was the tires need balance but it wasn't the case..
The noise you recorded sounds like one gear just popped (lack of better description)....strange....

SlyAccord

No no no haha, I was driving through parking garage..

listen to this one..

The sound starts about 7 seconds and sounds like a table saw. The "bumps" or "knocks" you hear is me driving over the groves in the garage..lord jesus if those knocks came from my car

Cooldude01

I couldn't tell what it is....it's just strange and that's not the noise I experience with my car....You can't duplicate it at the dealership?? How about letting listen to the audio see if they can tell what it is...

SlyAccord

Car was at the dealer and they couldn't duplicate it. Said the tech checked the propellor shaft and it looked fine.

I'm going there tomorrow to play the clips for the actual tech to see if it gives him an idea what it could be as I don't think the advisor had him listen. They want me to go on a ride with him but I have no idea how to duplicate it..ugh

This just popped into my head..I have dual led switchbacks. a while ago, my left one was staying solid white and not flashing Amber or flashing at all. Curious I just gave the lens a little smack and it fixed it.

My setup has resistors, could the resistor be buzzing?

SlyAccord

I got them from ijdmtoy

So I was told its the power steering and its "normal" but they can't do anything until they get a code on the car. They were able to hear the noise and then I got a notice on my navi driving home that the power steering motor may not be working properly! The rep said it could be just because we were messing with it.

Has anyone had issues with their power steering motor? its a '12 awd advance

Cooldude01

Power steering Motor??.
Bring your car to a different dealership see if they give you the same answer.
