I have noticed the same issue on my 11' WRX LTD with 18K on it. I only have the gritty feeling in the clutch after driving a little harder on the car. I have not inspected the reservoirs yet but it does go away. I am thinking of just flushing out the system with a better fluid and making sure it is properly bled.

I had Subaru look at it with the 15k mile checkup. They claim they didn't notice anything out of the ordinary. This is bologna. Some days I'll feel nothing what-so-ever in the clutch all day long and other days, I can feel a very distinct vibration (imagine a stereo speaker being off versus vibrating as music is played with your leg against it and that is what the clutch pedal reminds me of. It's not severe. If anything, I can feel the grab point of the clutch easier with the vibration, but it's very disconcerting since it didn't do when I got the car and none of my past 4 cars EVER did it, even at 130k+ miles.

Sitting in the dealership waiting room (City Side in Belmont, MA) as I write this. My third time back here having them look at it. This time a tech will be doing a ride along with me.

I notice it is most prominent at the top and bottom of the clutch throw. I can replicate the feeling by leaving the car in neutral, holding the RPMS around 1,500/2,000 and pumping the clutch.

It is mostly felt at slow speeds in lower gears. I've noticed it a lot when cruising in first and coming to a rather quick stop, depressing the clutch.

I have also had issues putting the car in reverse from neutral in the mornings. It will take 1-2 tries till it goes into gear. I've also had issues stalling on rare occasion when starting off in first. Something wrong with the engagement point? (From what the tech said, this is a common occurrence with our 5spd gearboxes, nothing to worry about)

Ill report back with the verdict in a little bit.

Update:

Looks like I might be having my tranny/clutch pulled and inspected. Will know the end of next week.

Update to the Update:

Last week Subaru replaced my clutch, flywheel, springs, and TOB under warranty. The issues were found to be caused from a failed throw out bearing. It was also noted that the Tech found that my clutch was slipping.

All of the previously mentioned symptoms have gone away. The clutch is smooth as butter, and is much much lighter than before. I didn't realize just how hard the clutch was to actuate until now. It seems I had just gotten used to it over 12k miles. No wonder I have lower back pain on my left side.

On an unrelated note, my OEM Blue Fram filter decided to stop holding a seal and barfed up 1+ Qts of oil . Come to find out it was one of the Recalled Fram filters (http://fram.com/sites/default/f/uplo...stribution.pdf). I was almost due for an oil change, so I guess it isn't all that bad.

Updated update to the Update (Trace busta busta busta)

After a week of sweet bliss the feeling started creeping up again. Now it's in full effect, it not worse than before. Pedal is stiffer, vibration present.

Brought it back to the dealership, tech looked at it. Said he did feel the vibrations, noted that it wasn't normal when we went out on a drive. I left it with the dealership for the past two days. They are telling me there is nothing they can do at this point. Said the tech found the issue in some wrx's off the show room floor. Whether i believe that or not is another story.

I am going to be drafting up a letter to SOA expressing my concern, displeasure and request that it be noted, so if there is a clutch/tranny failure in the future (big concern is after warranty) that it be covered.

I am bummed out.

Will be watching for info. Personally, while my car has this vibration, I haven't thought of it as something that I'd want the transmission pulled out to check. Maybe my tune will change if it turns out to be a real problem for you. Probably not.

So I've been having this same issue on my 04 sti. Took it to the dealership and they said I needed a new clutch. About $1500 later I get my car back from the dealership and I don't feel the vibration anymore. I go out to my car the next morning and notice there's a huge puddle of transmission fluid under my car. I look underneath and the dealership forgot to put the locking pin back in the axle and the axle was half way out of the transmission!!!! I get the car back and now my pedal is vibrating again whenever the car is cold or is reved over 1500 rpms. Same issue I took it in for!!! I took the car back to the dealership again and now they're saying that the clutch is fine and that the vibrating clutch pedal is normal. WTF!!! I'm just gonna keep driving it I guess till something s**ts out.

My 2013 WRX has done this sporadically since I drove it off the lot.

It seems like it's during turning into my driveway, so I just assumed there's some diff vibration in tight turn being transmitted through the driveline.

My Landrover used to judder like hell doing this in 4WD, so a bit of minor vibration doesn't seem like a big deal.

I guess I'll just keep an eye on it. Aside from the vibration, there's no other issues present.

WRX 2012 26000km, been having the same grittiness through the clutch pedal since 20000km.

Only happens after a WOT, goes away with a few pressure. nothing if I keep it under 4000rpm.

Went to 2 dealers, nobody could reproduce.

Going to try a 3rd one, supposedly good with warranty issues on tranny...

I'm also going to send & print that thread!

Hope to get to the bottom of this, a new clutch on warranty would be the least.

I've started having the same issue lately on my '11 WRX. It has 20k miles.
Didn't have a chance to discuss it with my dealer yet.
There is a thread started not so long ago on our Montreal Subaru Club forum.

I think some on here are having different issues than others. I only get grittiness some of the time (although it's rarely vibration free like it was originally on and on my last WRX entirely) and it's not a really bad vibration (I can just feel the clutch engaging, etc. through the pedal as a light vibration) and revving the engine, etc. has no effect one way or another. It's the same whether I'm shifting at 1500 RPM or 6000 RPM. Once in awhile it'll go away completely for an entire day or so. I don't even see a strong correlation with the weather now that it's warmed up a bit.

I'm still betting on a lack of grease on the clutch fork, but until it gets worse, I don't think it's really worth pursuing. There's no signs of clutch wear from the pedal (still starts to engage fairly close to the floor when letting the pedal out and fully engages about 2/3 the way up (or disengage in the opposite manner/distance if pressing down). I see zero signs of slippage so I'm thinking whatever it is, it's not the clutch wearing out. It might be uneven wear on the disc or something, though, but I'd expect more of a tick/chatter in the slip zone, not just a general vibration that doesn't seem to speed up or slow down with slip. OTOH, I don't feel any vibration in the pedal at the far end of the travel up or down, only in the engagement zone.

im at 52k miles. ive had that symptom forever. like i mentioned earlier in the thread it basically disappeared, however it came back but not as bad, and doesnt happen as often. it only happens when i shift hard at redline from 2nd to 3rd.

basically it is not worth pursuing is what im trying to say. i'm hoping it will go away completely when the clutch is replaced someday due to wear.

i believe it's also worth mentioning that i thought my belt pulleys were squeaking, but i figured out that it's the clutch or clutch fork/throwout bearing. when i pulled over to park, but still had the clutch vibration before it goes away eventually, when the clutch is fully engaged (not stepping on the pedal), it sounds like a squeaky pulley. when i depressed the clutch the noise goes away.

this squeakign noise goes away when the clutch vibration goes away after normal driving and/or pumping the clutch as per discussed in the thread.

My throwout bearing made an audible noise from the first week. I could hear it ticking when in the garage or sitting next to another car with my windows down. It's not real loud (although I do have the SPT exhaust so it has to be loud enough to hear over that rumble). It disappears if I push the clutch in so I knew immediately it's the throwout bearing.

I had another car over a decade ago ('88 Cavalier Z24) that had a much noisier throwout bearing (high pitched whistling noise) and I probably only made it worse by sitting with the clutch in at red lights (due to the previous owner having worn out the 1st gear synchro the car was very hard to get into first from neutral at a stop so it was much easier to get it into first before completely stopping and just holding the clutch in. But I had the car for almost 90k more miles and the bearing never seized so I'm not terribly worried about the WRX ticking a little bit, but still, you'd expect a brand new car to be dead quiet in that regard.

ive read about subaru TO bearings, and the noise is not just present in the WRX/STI but in all of them. it's "normal" and i've never worried about it either. I do hear that same noise once in a while in the mornings, if i'm really listening.

I've had an issue with TOB noise on my '08 WRX.
The grittiness issue on the '11 is something else.

I've got it again this morning after a single WOT in 3rd while getting on the highway.
The feeling in the clutch pedal lasted for several shifts over a mile of driving.
Only when I stopped at a stop sign and pumped the clutch pedal in neutral several times that it went away. And I could tell the exact moment when it did.
When the problem is there, I feel the grittiness throughout the whole pedal travel. All the way down and up, with the tranny in neutral or in gear, driving or stopped. And then, after few pumps, the feeling goes away in an instant.

Fixed or replaced with another defect? I've seen a lot of premature clutch failures on this generation WRX, usually under 12k miles or so, some as little as 3k miles. I'm at 18k miles now and there are no signs of slippage, but the clutch is heavier than it was when I got it. The engagement point hasn't changed, though (should start moving higher when the spring runs out of movement and thus the pad is wearing out).

It could slip earlier, of course, particularly if glazed, but it's hard to tell just by the feel. My last WRX felt like this one does now it's entire life that I had it (from 36k to 80k miles) so I don't know if it just tightens up as it wears in from being brand new or it is indicating some wear. I had a Ford Probe GT to 140k miles and it was still on its original clutch (similar for a Z24 and the last (2004) WRX was at 80k with MANY MANY launches on it and still wasn't slipping at all when I traded it in) so I think I shift reasonably well. If this clutch fails in the 18-30k range, I'd say there's definitely a defect somewhere. Gauging by the way my dealer talks, though, most dealers just blame the driver when the clutch fails sine they get so many "Speed Racer" types buying the WRX that have more eagerness than they have shifting skill.

A WRX 2012 with the same clutch gritiness issue should have the whole thing replaced on warranty, bad TOB that start to squeal after a while...if the dealer keeps ignoring the issue...

Thanks for this update. I'd be bummed out too. This is exactly why I haven't wanted to try to get the dealership to do anything or look at this issue on my car.

I want to see if we can get to the bottom of this.

Has anyone tried to fix it themselves?

I've tried greasing all joints/pivot points on the clutch arm inside the car. That did not do anything.

Im curious to see if bleeding the clutch master cylinder will help. If it is the cylider by chance.

After the clutch job (clutch plates, flywheel, TOB, tranny fluid) the clutch was a dream. It was very easy to push, no binding/rubbing/vibration feeling. After a week or so it was back to crappy. (hard to push, rubbing/vibration.

What could possibly cause this? If it isn't something internal to the tranny, what else could it be?

Thoughts?

If getting the clutch replaced really does "fix" the problem for a few days, that should provide some hints. I wouldn't think the hydraulic system would need to be opened to replace the clutch, so I would not put my money on bleeding it having any effect. Correct me if I'm wrong. Same logic should go for the pedal linkage in the car

My guess would be that it has something to do either with the TOB or the clutch pivot. Maybe there's some lube that goes on during assembly and doesn't stay where it's supposed to? IIRC there are various posts about squeaking clutches that are fixed (at least temporarily) by somehow lubing the clutch fork pivot. Maybe it could be related?
