Steering Pump Whistle
 
So when I am idle, a faint whistling sound can be heard. I have asked about this in the past and thought it was simply my CAI causing the noise. However, the other night I noticed that it only happens when the steering wheel has no pressure applied to it.


For example, if I am stationary pointing straight ahead and the wheel is straightened out as well, the whistling can be heard As soon as I turn the wheel, the noise disappears. I can't tell if this is the case when the car is in motion as there is too much ambient noise to drown it out.

Anyone else experiencing this? Any thoughts on what it could be?

Did you check the fluid level?

Mine does this as well. Bought the car new 5 months ago, and the noise has been present for as long as I can remember. Figured it was just the nature of the system, but I've never had a car with a power steering system that whistled like that. Keep us posted if you find anything out. I haven't checked the fluid level myself (as new as the car is, I wouldn't anticipate low fluid levels), but it's actually a good idea that I'll have to look into.

I have the same very low whistle sound. Happens exactly as Runawayhacker described.

Eric Baker 11-18-2012 04:44 PM

Power steering pumps whine if they're low on fluid or if there's air in the system. But this usually gets worse when you turn the wheel, not quieter. Without hearing the noise, it's hard to say for sure.

I've just recently noticed the same "whistle" on my '12 with > 5k miles. I started it up with the remote start to let it warm up and as I walked down stairs I could hear what I originally thought was a squeaky belt... Power steering could also be a problem. I plan on bringing it in for service tomorrow morning. Any updates/explinations will be posted.

BlueRay-J 11-18-2012 07:08 PM

I notice it on my new '13. I thought it was the belt, but maybe its this too.

Comrando 11-18-2012 07:32 PM

My old lady whines like this. It's getting worse :laugh:
You don't want to hear :rolleyes:

Is the wheel straight when you park? If you spin it while stopped it will remain under load. Go past center 1/8 and back to center.

We apologize for the frustrations you may be experiencing. Have you had a chance to go to a dealership for a proper diagnosis? They should be able to pinpoint the concern you are having.

Please let us know!

I was persistent with my dealership about the whistling from my car and got an experienced technician to drive around with me... this was after I had tried to get them to listen to some recordings. I was almost positive it had to do with the steering because it would get louder as the steering wheel was being turned.

The technician told me that it was the plastic intake. He said that there's probably defect/bump in the plastic that's causing the whistling. He also said that a lot of GM trucks had this issue at higher revs (mine was at a very low rev). He pointed out that when stopped, the whistling gone/faint, but as soon as the revs get a little higher, the whistling will start.

I hope this helps someone..

I notice a whistle or whuring sound when at low speeds and turning. As I turn the wheel you can hear the sound, whuuuuurrrrr. When driving straight slowly I don't hear it.

I had this as well, and when I told the service tech, he had it checked, and a seal was bad. However, on the '11 SS this is a sealed unit, so the entire rack and pinion had to be replaced, thankfully under warranty. They had to keep my baby overnight to be sure the bubbles in the system were gone before alignment, but they gave me a rental, an Impala... gold (bleah), but hey, this is the nicest the dealership has ever been to me. I will only work with this tech from now on.

Good luck,

Jason

2013 Camaros have electric power steering now, so you definitely don't have the same issue as this person as their is no fluid or belts for your power steering.

BlueRay-J 01-05-2013 07:21 PM

Then it's just the belts for me. I hoped it would go away, but it's annoying me enough where I'll have to risk a dealer visit.

I'm having EXACTLY this problem right now!

When the wheel is in a "relaxed" state (doesn't necessarily need to be straight) there is a high pitched whistle... like air sneaking through the ventilation system but its definitely from the steering because... apply ANY amount of pressure to the steering wheel in either direction and it goes away (until the wheel is relaxed again). I can also hear it from out under the hood, but with all the other ambient noise there, its harder to spot. But if you just stand still and listen, it sounds like a periodic cricket sound. It can be hear while driving too, but is largely masked by road noise. You notice it more by its absence whenever you change lanes.

Using my iPhone connected through the bluetooth I was able to actually capture the sound quite well. I'll see if I can post it here later. I've got an appointment at my dealer tomorrow to have it looked at... will post results.

Hi Rally-RS/SS,

It looks like you may be experiencing a similar issue. I would recommend taking your vehicle into a dealership for diagnosis and service also. Could I assist you in setting up a visit?

Thanks Reggie,

Its at the dealer as I speak. I sent them this thread and they also eluded to some sort of bulletin (not necessarily a TSB) that made reference to it. Should be done today or tomorrow. I'll let everyone know what the outcome and solution was (assuming it comes back corrected).

Great news Rally-RS/SS,

That sounds like a good plan, I will be awaiting your update on your vehicle and hopefully we can get this issue resolved quickly.

Well, the dealer changed out the steering rack, but sadly, the sound is still there. Sounds exactly like a tea pot that is just starting to whistle. It's slightly more noticeable when revved, but then the exhaust is louder too so hard to notice that its more pronounced... But it is. :(

Not sure where to go from here... Ideas anyone?

I have this whistle kinda sound when I first hit the gas just slightly. Does yours do this as well?

Vespula2012 05-21-2013 06:47 PM

No, mine is isolated to the steering, and is only present when the wheel is in a "relaxed" state. Turn it even the slightest to one side of the other and the noise immediately stops. It gets slightly loader with increased RPM, but not very much so. If you have the radio or fan on, you almost don't notice. But if its a "quiet" driving time (no radio, no or low fan) you can hear it steadily while your driving straight and goes away whenever the wheel is turned. Good luck with yours!

Vespula2012 11-18-2013 10:41 AM

Does anyone have any further updates on this issue? I'm still periodically vexed by it. Luckily it doesn't do it all the time. But yesterday I pulled into a parking lot and it was especially loud. Fortunately it stayed that way long enough to get it to the dealer and for them to also hear it.

After the rack was replaced it has still been there periodically, and faint. But yesterday it was notably louder. Today it is silent. I hate issues like this. When its present, it drives you crazy!

tezell 11-19-2013 10:09 AM

I have a 2013 V6 and I have a whistling noise when accelerating. Although I describe it more as a chirping or high-pitched whirring. It happens when accelerating, lessens or goes away when I let off gas. Push he pedal, it's back. Mine is exactly as you describe as far as barely noticeable with radio on. I hate it because I can't have a "quiet drive" with radio off or else the noise drives me crazy. Dealership said they couldn't find a problem and all noises are "normal". Very unhappy but not worth it to go back to the dealership. I'm looking for info as to whether or not it could be fixed with any modifications. They comment above regarding the plastic intake is making me think maybe some mods would fix the issue? I don't know....

My 12' SS does it also. The dealership replaced the steering gear this week and it still does it just not quite as loud, YET... It will only do it when I'm not turning the wheel. After it gets warm on a long road trip it gets louder.
I was told I have to live with it, all of them do it. Not exactly the answer I was looking for from the dealer.
