It gets stuck on the floor. ie. It doesn't disengage. Kind of scary. You let up the clutch and the pedal stops halfway. So now you're in gear, your foot is not even touching the pedal and the clutch is still 'in'. You can re-press the clutch but even that doesn't really do much, since it's pretty close to the floor anyways.
In my case I had to apply the parking brake, shift to neutral, wait a few seconds (maybe 5 or so), then go again...
I've had it happen after a lot of stop n go and also on a couple of hill starts at a stop sign or something. then the smell of burning clutch comes. (or at least it did in my case)
You just have to hold off for a bit and then try again
BigSash I'm not trying to be an *** but I think we've passed the point where we're trying to establish if it's a legitimate problem or not... There's obviously some condition that makes the clutch stick, we just don't know what it is or how to solve it long-term. Noone should have to double clutch a car with syncro mesh even if that was a good sensible solution.

k you r not being an ***, and i obviously just switched disengaged and engaged my mistake.
Either way the double clutch should solve it, but you are right you shouldn't have to double clutch a late model car =]

You shouldn't need to do that to take off any quicker, just shift faster or hold the clutch lower not so high to "feather" but high enough that it is just below the point at which it engages not actually engaging until your finally ready to go, rather than feathering and engaging/disengaging repeatedly. My guess is you engaged the clutch while feathering and when you backed off and on again feathering you just got something stuck lol, did you happen to look at your revs when you are still gassing but clutch won't disengage? the acceleration is probably not doing anything because the gear isn't engaged and clutch is stuck, once you stop revving, the gears stop and let the clutch loose.
Clutch should really be used as little as possible. You shouldn't even touch it if you don't have to, and when you do it should be fully depressed.
just my $.02
I have driven a lot of MT cars over the years and used to live in a very steep area of san francisco where clutch drivers have to replace their clutches annually.
(clutch drivers = people who lightly touch the clutch pedal while in gear and driving, just resting a foot very lightly on the clutch pedal. this is bad and lots of people do it without realizing it. when you are not using the clutch your foot should be 100% off the pedal and next to it)

In other words, right when you notice the clutch is not popping all the way into it's disengaged resting position, you resupress it and try to shift again cleanly?

Only reason I ask these simple questions is 1, double clutching has nothing to do with launching, its simply the old fashion way to downshift and 2, how is it driver error when the clutch gets stuck? I've driven numerous manual transmission cars and this is the first car where the clutch has gotten stuck. Another thing, this has nothing to do with shifting quicker, the problem is the clutch gets stuck, the engine over revs and even if you do shift into second, the car has bogged down to an unsafe power band that could potentially get you side swipped or rear ended.

right that is why when the clutch gets stuck you depress it fully again and then shift into first at lower revs (since you lost power). Or if you were going to shift up and it got stuck double clutch move to neutral and then back into the same gear. d00d i def. know what double clutching is, and while I own an automatic g35 i have driven 6mts and over 100 other MT cars. I used to have to double clutch my camaro to shift into reverse.

Ok, problem solved for my '05 G35c. I am @ 13000 KM at the moment, and bought in the car for fix'n just 2 days before. "Sticky Clutch" and werid sound coming out from the clutch side when engine is warm (2000-3000rpm). What they TOLD me they did was;
1. Changed the flywheel, to resovle the werid "dig dig dig" sound when the engine is warm / hot (depend how you say it).
2. (didn't told me what they did about this, but I could tell what was changed) They changed my "pressure plate" if I didn't say it wrong. As some ppl here know, '05 clutch is more deep than the '03-'04 G...and now I have the same feeling clutch as the '03-'04...Doesn't make scenes to change my '05 "pressure plate" and changed to the '03-'04, ya but that's what they did...now my clutch is NOT deep, and I have to take time to get use to it again...
Anyways, I just got it and drove like 20km on it. I will still need sometime to get use to it and see if there would be anymore problem. Let you guys know once I got the answer.
Ahh, yes, the 5th gear...can't get it in all the time, think they dropped my transmittion for checking and did something wrong??? after replace it back up? Anyhow, I will be bring it back to the dealer again for this matter...
Keep you guys update!!

KCC Baby which dealership fixed your car?
I have had all the same symptoms. I've sorted through the bickering and explanations but until it happens to you, it's hard for someone else to understand. I have had this problem under moderate throttle and heavy throttle. Infinity dealerships all over Florida say they have never heard of it. What dealership did you go through?

I would go to an Infiniti dealership, if I were you.

Well, this happened to me this AM in my 2004 6MT. All the same stuff. (Moderately high RPMs, Getting ready to merge, and then can’t because someone moved into my target lane (clutch feathering, revs down). This repeated twice in about 3 seconds, and when it came time to go, well….
The best way to describe the feeling that while the clutch "sticks": It feels like your seat is moving backwards while your foot is coming off the clutch.
And man, that smell.... I know there has been some premature wear, now I need make sure it doesn't happen again.
Not too thrilled….. I guess a single hard launch would have been better than this crap.

I also had this problem. Replaced the factory parts with a JWT clutch, pressure plate and aluminum flywheel. No problems.
The stock pressure plate is garbage. Upon hard acceleration while feathering the clutch pedal, the pressure plate does not hold enough clamping force and does not fully engage. This causes the clutch plate to begin to slip. As soon as slippage occurs, the pressure plate stops in its current location, which stops the hydraulic pressure returning the clutch to its original position. This causes the pedal to remain at the 1/2 waypoint. That's why once you let off the gas, the rpm's slow which allows the pressure plate to fully engage and return the pedal to its correct position.
I would be willing to bet you will not find anyone that has an aftermarket pressure plate that is experiencing this problem. Please post if you are......

Infiniti Satisfaction Guarantee?
What are the odds that enough people will have this problem and Infiniti will own up to it? They designed the car. In my opinion the weakest link should be the tires on the pavement, not the clutch. I just got home from the dealership and they say they don't have reason to open it up because they can't re-create the problem. I asked them if they got on it and was told that they don't condone excessive driving. B.S. That wasn't what the salesman was saying prior to purchase. I bought a 298hp RWD sports car. I'm saving my service slip so in the future I can say this problem was hapening at 4000 miles. BTW, how much did the Jim Wolf clutch combo cost to have installed?
