Hi there, wanted to get your expert opinions on what is probably a common Santa Fe issue. I have a 2005 V6 2.7L model which has travelled 81,000 miles (131,000km). The power steering is and has been working fine, but over recent week has developed 2 symptoms :

a) The reservoir overflows (see pic)
b) There is a whining noise when the vehicle is travelling and when turning the sounds modifies to more of pressure-release type sound. When the vehicle is stationary, the noise is very evident when turning the steering wheel (please see video here : Power steering noise - YouTube )

Other things to report are that the reservoir is full but has not needed a top-up for months. The power steering pump appears to be leak free. I have a slow drip from the rack & opinion area (detected at Hyundai first service - about a few drips per day and they decided it didn't warrant fixing)

I have read on this forum the issue may be related to the reservoir filter becoming blocked and this ties in with the fact the rack and pinion has a known drip leak, but I never need to top-up the reservoir.
Any advise on this greatly appreciated.

All fixed - I assumed it was a reserve blockage from the above thread, so first drained the reservoir as much as I could. Below video link shows how to, but instead of using a pump as per the video, I just went down to the variety store and in the kitchen section picked up a $2 cooking syringe (flavour injector, which holds a couple of fluid ounzes). Then attached some plastic aquarium pipe (about 1/4 inch dia and about 6 inches long). This was perfect to get thru the reservoir hole which is only about 1/3 inch.
I then removed the inlet and outlet pipes. The reservoir then pulls off the metal bracket, as it has two plastic lugs on its underside that mate with rubber mounts in the metal bracket.
The nylon mesh microfilter at bottom of the reservoir did not look too bogged-up, there were some fragments but is a VERY fine mesh, so figured would not take too much residue to impede the flow of the fluid.
I gave the filter a good blast with degreaser, then slooshed the filter a few times with more degreaser then flushed for a few minutes with cold water and air dried in the beautiful Sydney sunshine for 20 minutes. Double checked it was 100% dry then reassembled.
I refilled the reservoir with clean fluid and when I restarted the engine, the change was almost immediate. The pump screeching noise completely disappeared after a few seconds as the fluid (assume now circulating properly) made its way thru the system. The steering wheel felt immediately lighter to turn. I then did approx 6 empty-then-refill flushes per the video, starting the engine and turning the wheel inbetween and the fluid changed from a brown colour to dark red. The system is 0.9 litres, I flushed the system with about 1.8 litres of new fluid. The fluid was noticeably clearer and about half the viscosity of what I had flushed out too. (probably still need to put another litre thru it to bring the fluid back to a lighter shade of red).
So with the job completed, the power steering is now much lighter as a result, the reservoir no longer leaks thru the lid and the pump noise is all gone - so appears fully fixed for $22 total cost !! :)
One tip if you think you have a similar reservoir problem to this, is to check your reservoir with the engine running. Look at the side of the bottle, the top fluid line should be clearly disrupted and agitated due to the fluid circulating thur the bottle. If there is not much movement of the fluid surface - you have a circulation issue with the reservoir or pump or other blockage, but as I have read in this forum and from my own experience here - ALWAYS start by reservoir cleaning and fluid flushing as described here firstly, as could save you big bucks.

You are right. This is a very common issue although it did not manifest itself in my 04 until well past 100,000 miles.

Thanks for your reply Andrew. Are there any other common problems to watch out for? I've also had the top and bottom water hose leaks where they attach to the water pump. That was a couple of months back. I think I am overdue for the timing belt change too.

I just worked this problem on my 05 with 157,000 miles. The fluid was black so I drained the reservior and removed it. I flushed it with brake cleaner until it was clean and let it dry. Once dry I mounted the reservior again, connected the lines and refilled. I cycled the steering wheel through full range about 6 times. Once again the fluid was almost black, so drained the reservior again and serviced with new fluid. I repeated this process until the fluid remained clean. It took about 3 quarts to completely flush the system. By the end of the first quart of fluid the noise had completely gone. I plan to check it again in a week to see it the fluid remains clean. If it isn't I'll flush again.

My rack and pinion unit also had a small leak, so I used the power steering fluid with stop leak in it. I'm hoping this will solve that problem also.

Ah - looks like most of the detail on this problem is covered in below thread. Looks like the first thing for me to do is clean the reservoir filter.

Glad to see that thread helping people out. Unfortunately it seems my bad luck with power steering has returned.

As I said in the original thread, the issue went away after the mechanic tried several pumps, several flushes and replaced the hoses and clamps. He did the reservoir LAST despite my bringing it up on first visit (thanks to this forum). That and another flush or two made the issue stop, for a few months anyway.

It's back again as of today. No visible leaks, but the whining is identical and loud. I'm wondering if the pump suffered too much damage in the trial-and-error process and was already on its way out by the time the reservoir got replaced. We're talking about a good 4 weeks of driving it with noises, while the mechanic tried different fixes.

Actually I hope it's the pump this time since its under warranty. An also because the reservoirs are a bit of a pain to order (in hindsight I suspect that might have contributed to how hard the mechanic looked for other causes before he gave up and ordered one).

Back to the garage tomorrow...

JLCK, I'd like to know what the garage says for you. I had gotten a timing belt replaced and ever since I get whining from the power steering. Even replaced the reservoir with no luck and cannot find a leak anywhere. It's been that way for a few thousand miles now. At least you aren't alone! Good luck!

No problem. I'll be sure to follow up. Unfortunately I had to postpone my trip back to the garage (wife just had a baby and can't drive, so me & the Santa Fe have to pull double duty for a few days, noisy steering or not).

Here's the weird thing though: I drove the Santa Fe today for about 3 hours over the course of 3 different errands, and while the pump sounded slightly louder than normal in general, the REALLY loud, troublesome noise never surfaced this time.

When the loud noise happened two days ago, it was after I had to slam on the brakes and swerve hard to avoid being T-boned by another car.

I wonder if that action caused a temporary strain on the power steering that settled down once I parked the car and allowed it to depressurize. (But I don't know much about cars, so if that theory is ludicrous, I'd be happy for someone to set me straight).

I have had the exact same experience: I had a timing belt replaced, and ever since my power steering has become noisy. Still operates properly, and PSF reservoir is full.

Any idea what causes this?

I had this crazy noise going for last 4 months,and could not find what was the cause.Zylion ideas and blames on timing,idler,pulley bearing's noise,old PS fluid,that I have changed many times switching from Prestone to synthetic Castrol ATF. No luck.
My advise to You is simple one,and the job is not terribly complicated-get the PS pump out,and get Yourself 3 arms 3" puller,put the pump on the working table,remove 4 bolts and carefully split that thing.If you carefull ,gasket may be reused.My problem was worn out ball baring-there is only one inside.I have change that-less than $10-and problem stopped.No more whining.

I had the same over flowing P/S reservoir and then a very faint whine from the top back passenger side. (I had the power steering pump replaced at the dealer 3 years ago). The fluid in the reservoir never got below the min while the over flow problem was happening, I watched it and would add if needed, but didn't really have to. I got a new Power steering reservoir from the dealer and had a regular garage put it in. There is no more over flow now and the fluid level strays where it should. There is no leaks under the truck ether. However, the faint whine is still there and after 45 minutes of driving a loud whine starts. After stopping and coming back out a while later to drive it the whine is again very faint unless I drive it 45 minutes or more. Short distances it's stays a faint whine. It is not louder if I turn the steering wheel all the way to the sides at all I tried to check. The steering feels normal too. But after I stopped it when it started to whine after a 45 minute trip and came back out it didn't start so easy, but the slow start was just that once the last few days in the same situations it didn't start slow after the cool down re-start. I hesitate if its the P/S pump just because its not that old only 3 years old and done by the dealer. Did you ever figure out what it was on your's?
