Happened on my Sedan after approx 20k miles. 1st allocation. It was the fastest fix I have ever seen. I had the car trucked in, and 45 minutes later, I was on my way. They really didn't like that yellow car sitting WAY up there on that flatbed for the world to see.

I got bit by the power steering bug! lol. Today at Buttonwillow coming hot into turn 1 at the end of the front straight I was braking and then turned in...uh oh.....I see smoke billowing out the back end...I thought I blew the motor until I kept turning and realized that it had become extremely stiff... whew! I pulled in and jacked the car up and sure enough one of the jam nuts was so loose I could spin it around with one finger. Luckily I tightened it up and wrapped teflon tape against it so it couldn't back out again, then had a friend drive me to get more fluid to replace. No problems the rest of the day with that, but I'm taking it in next week to get a full inspection and fix.

ps: during this run my passenger had commented that his coworker who has a wrx wagon had this happen to him on the street just recently. I laughed and said I knew that people had been experiencing this problem, but personally had not yet checked on it. One lap later murphy's law took affect... :P

i just went to an independant right by Honda and they tightened it up. I didn't know what was wrong but my steering just started going away when I was getting lunch. (on a brighter note, my unichip and exhaust should be here next week)

So, other than the clutch, how many other problems are there that are known publicly?
Check the problem poll thread in this forum. Common problems include clutch/tranny (17%). Potentially serious problems include ABS malfunction (3%). Also noted in "Lemon-Aid, New Cars 2001" publication.

JD Powers 2001 Initial Quality Survey ranks the Impreza at 185 if 195 models, with about 200 defects per 100 cars. This polls 50,000+ owners as problems encountered in the first 3 months.

Consumer Reports puts them on the recommended list, so if you can get your dealer to fix your initial defects, it seems a good car for long term durability.

jamz,

200 defects per 100 cars mean 2 defects per car on average. Keep in mind some cars will have no defects at all, some will have a dozen.

Here is some experience I have gained from working in the OEM automotive industry, on steering systems.

It was recommended never to run the pump when dry. Whether you were preparing a pump or car for test, or testing the engine which just happened to have a pump attached. I don't know if the pump on our WRXs uses a bushing or bearing for driveshaft support, but neither likes to spin without oil. For those that fixed their cars at home after the fluid had leaked out, you might want to call this out to your dealer so that if you have pump problems in the future he might be inclined to help you out. For the owner who drove 3 hours in colorado without power assist, did the dealer replace the pump? Should have.

If you have loss of assist when the engine and pump are hot, I think you have lost some "compression" in your pump. They do not use pistons but the analogy is a good one. I believe the pump is a vane style pump. The pump rotor spins and in the process intakes fluid into a volume bounded by two vanes, the rotor, the ring, and the pressure and thrust plates which sandwhich the rotor, ring, and vanes. The rotor and vanes spin between the plates. The clearance between the rotating parts and the plates is very small which limits pressure losses once the fluid is compressed. As the fluid heats up it becomes thinner, so more susceptible to leaking through these clearances and not providing assist. As you steer the car, more pressure is required to provide assist as you turn further into the corner. Your steering lifts the car due to kingpin angle, more turn - more lift required. Your car may have enough pressure to handle assist near center, but not near the corner.

If you run the pump without oil, it will heat up. The metal parts will expand. This may cause the rotating parts to contact the stationary parts, scoring them. This will limit the pump's ability to provide pressure the next time, because you have created leak paths.

Lastly, it appears that the fittings on or near the gear do need to be checked and maybe tightened. They likely use o-ring fittings, so don't reef on them as you will crush them and they will leak. They *should not* loosen over time, even with vibration. All the big 3, and likely the major import makers too, test cars to 100k miles and beyond. During this time you aren't allowed to retorque bolts or fittings so they pass test. Now maybe they do loosen on * this car*, but that would indicate some bad test planning and results gathering on Subaru's part.

Good info from all, thanks.

Don't think you were talking about me, but I drove for about 3 hours after losing all fluid. I took it into the dealer (so I could get it documented), they refilled the system and verified that the pump wasn't making any noises, but they wouldn't replace the pump at that time... The main thing is I have it on record now in case the pump goes bad in the future.

Does this loss of PS fluid cause any long-term damage to the steering system?

Austin, I was talking about you. If you were driving highway, the rpms were fairly low which is good. And, if you lose all the fluid except a residual amount in the pump bearing or bushing, the pump won't be making any pressure which is good in one way. Without pressure the pump's plates aren't forced together as hard, so any scoring may be less. Its probably worse than it is good, because if the pump is a bushing pump (vs bearing), the bushing will have minimal hydrodynamic support without some pressure in the pump, and the driveshaft will probably wear the bushing prematurely, because the belt load is pulling on the shaft loading up the bushing. If its a ball or roller bearing pump you aren't relying on this hydrodynamic support in the same way. I don't know what effect it may have on the bearings.

I think any long term damage would be confined to the pump. The steering gear can steer just fine without any fluid in it, tho your arms will get tired. I suppose if you drove with no fluid in the gear for a long time you could cause some wear in the rack tube area due to a dry piston. The lines will have an easier time of it if there is no pressurized hot hydraulic fluid in them, so they will be ok.

I would be concerned about the pump if run without fluid for anything over a couple of minutes. After all, its a Subaru warranty problem that led to the no-fluid condition, not an oversight of the owner. The higher the rpms the quicker the pump will heat up due to internal friction so the potential for scoring is greater.

Any Subie experts know if the pump uses bearings or a bushing to support the shaft?

Mark

Actually- you were talking about me- in reference to 3 hours across Colorado anyway, and yes I tried to keep the revs down as low as I reasonably could.

I was a little worried about the pump at the time, (they were closing their shop so I had no chance of getting any service beyond tightening and topping off) but it has been trouble free for over 25,000 miles since then.

Both the dealer I bought it from and the one that does most of my regular service have been made aware of the incident and neither has suggested the need for pump replacement- especially since it seems to be working fine.

I figure the pump will probably just give up the ghost the day after the warranty lapses

Just went out to the garage to go for the morning drive and when i turn the steering the pump makes all kinds of loud noises and left a trace of fluid on the ground.. Im gonna go try and see if i can tighten her up so i can drive this weekend..

Car has 9500 miles.

Clutch slipping already also. Throw out bearing making noise too when engagement in nuetral like in a garage or something quiet..

Just went outside and when your looking under the car where the line comes down from the resevior i take it there is a little 14mm inline nut thingy.. Hard to explain but once ya get under there just follow the line going up and you'll see it. tighten her up as i did. took 2 minutes and now all i need is to get some dextron auto tranny fluid as they reccomend.

All fixed

Put me on the list. I was on the track and got black-flagged because of all the smoke. Before I could reach the paddock, all the fluid was on the track and the power steering was gone. The dealer fixed it, but they didn't let on for a second that they had ever seen the problem. Huh.

OK, ok

After reading all of these posts, what have we determined/learned, if anything?

Was there just a bad batch or is this really happening to everyone? AND if it has not happened to YOU yet, don't worry because it will?

Thanks

Hmm, happened to me this morning. I drove home from work last night in a lot of snow, having a little bit of fun on the road. Nothing serious, but just some small, slow drifting (<15 MPH) around corners.

This morning, I wake up to find PS fluid all over the ground. I'm taking it into the dealer to see what the deal is.

Edit: car has 16.5K miles, first allotment, built March '01.

OK, brought it to a non-mod-freindly dealer this am. They said that it was related to the underdrive pulley somehow but were not going to look at it further due to the engine being "half-aftermarket". Is anyone else running an UD pulley? Mine is a vishnu, so it's not too underdriven. Only other engine mods are ITG filter and an SBC-id EBC.
