Noise From Power Steering When You Start Your Accord? Here Is The $100 Solution

Your Honda Accord makes a loud moan or similar noise when it is cold and you turn the steering wheel. Here's the cause of the problem and the fix.

If your Honda Accord has a loud steering sound when cold, you may be in luck. We researched the problem in our own 2006 EX-L V6 Accord and discovered that the problem is air entering the system via a defective o-ring. Honda has a TSB on the subject.

The problem is manifested as a sound when the car is cold and you turn the steering wheel from left to right and back again. It sort of groans or moans. It is an easy sound to detect. Honda says of the sounds, "A moan or whine is heard when turning the steering wheel when the engine is cold. There may be air bubbles or foam in the power steering reservoir. The noise usually goes away when the engine warms up."

Honda says the probable cause is "Air is entering the power steering pump through the inlet joint O-ring. This causes bubbles to form in the power steering fluid, leading to reduced pump performance."

We posted our problem in the CarTalk Community and one of the members there quickly shot back a TSB that was exactly right for us. Thanks, member Nevada_545!

We took our car to a local trusted mechanic, Mark McMullen at G&M Services in Millis Mass. Mark obtained the parts needed for the repair on Amazon. He followed along with the instructions and the outcome was great. Zero noise. Even better, the cost to perform the repair was very modest. Just $100. Compare that to multiple hundreds for a new power steering pump and you will see that this is a happy outcome.

If your Accord is having a similar problem we suggest showing your mechanic the TSB linked above.

$8.22 for 91345 o-ring part??? Are you kidding me! I just did this on my 07 Accord and got the part from dealer. It was less than $2.
