My power steering pump makes a whining/moaning noise when the car is cold. As soon as the car warms up the noise goes away. Any ideas of what this could be? Fluid is at the recommend level

check the fluid could be low if so you could get power steering fluid or use automatic transmission fluid also try rotation all the right and left work the steering might just be low on fluid hope this helps

Probable cause is that air enters the power steering pump through the inlet joint O-ring. See Acura service bulletin 07-060. My 2004 Acura TL is doing the same thing and I am investigating whether or not it can be repaired under warranty.

I have a 2004 Tl, same issue. I received a recall notice on a power steering fluid leak - hope this fixes it.

I took my car to the Acura dealer and they told me the O ring was worn out allowing air to pass thru the pump. As the pump runs it forces the air out, causing the noise to stop. I was quoted est $115 to replace the O ring.

I had the same issue with my 2004 TL. The dealer fixed it under the recall in January and I haven't had a problem since...

I had the same issue. The o-ring in the power steering pump had to be replaced. no problem since.

There is a technical bulletin out by Acura on this. It's caused by air bubbles entering the power steering pump. The remedy Acura recommends is to replace the o-ring in the power steering inlet valve. They said that if your car is out of warranty, Acura dealer can ask their local Acura mfr rep and see if they can extend a goodwill reimbursement.
