Depressed Clutch Noise/Vibration
 

I recently started noticing a weird vibrating sensation, as well as weird clicking sound when the clutch is depressed(Pedal pushed in). I have about 3,000 miles on the car. This happens when I start up the car and in neutral. If I give it a rev over 2k rpm, the sound/sensation goes away. I am not sure if this is normal or not, since I seem to be having the exactly opposite issue as most. I did some searches, and most of the posts are in regards to chatter with the clutch (which should go away when the clutch is depressed). Of course, these symptoms only happen when the car is on, so I do not think it is the pedal itself. Sorry if I am explaining it wrong. Any help is greatly appreciated. Thanks!

Hey, yeah this is normal. You get vibration in the clutch pedal and also slight knocking too like something is hitting it.... it's weird but it's normal lol

Yup, I get the same thing. I think the vibration is pretty normal and the knocking sound seems to usually happen when you depress the clutch a little early or at certain moments or speeds .. If this is what your talking about it happens to most of us I think, if not all. But, if this is not what your talking about and your still concerned bring your car in to get it checked. Hope this helped.

^^^ I noticed the knocking.. rather a loud knocking sound... if I press the clutch too early.. and it usually happenes when I am shifting form the 1st to 2nd... so should I assume its normal?

Normal.

I noticed around 3k there was a small thud every now and then, lasted about 1k before it went away, guess it takes a bit to break er' in.

i haven't experienced what you described but i'm still breaking in the car (1,000 mi) maybe it would occur later on :)

mine makes that noise when i press the clutch pedal a little. it was like that from day one for me. even on the other z i test drove.

Thanks a lot guys for the feedback. I will still bring it in to the dealership sometime next week. I just wanted to make sure before I waste my time. I started noticing the mushy, vibrating feeling recently due to the cold weather. Unfortunately, it is not supposed to be sunny for a couple days before I test that theory. Thanks again!

Did you say cold weather? San Jose? how does that work?:icon18:

Global cooling :-P. But relatively speaking, it was warm for about 3 days, then got cooler.

It happens to me too and I thought it was because its my first time driving stick !!

Haha. I guess I'm Spoiled by the weather here.

I just took my car out again. I noticed that if I push the clutch pedal all the way down and hold it there in neutral, with the motor on, I can feel and hear the noise. I guess it is normal? Thanks.

:roflpuke2: coldest temperature I see on there is 56, thats speedo weather where i'm from :icon17:

^^^ hahaha.

my car with light weight flywheel
the noise is pretty bad
just idling make huge noise and rattling sound lol getting used to it now...

took mine to the dealer with this noise but i also had a pressure issue as well, they are replacing the release bearing on the clutch next week.

What kind of pressure issue did you have? Thanks. I really want to replace the throwout bearing also, as I think that is the cause. It just seems weird that the throwout bearing would be like this so soon (3k miles). My 06 Z did not have a problem and I drove that thing for >30k miles. Thanks again.

i had no pressure or very little pressure until it got to about 2-3 inches from the floor, then the clutch would engage/disengage. once i got it to the dealer the pressure issue was gone but was still making the noise. car is 3 months old bought it new with 60 mi on it, it now has 13500.

that's awesome. You sure drive a lot. Let me know what happens after the install and if the noise is still there. Thanks.

update: dealer has my car as of yesterday and they provided me with a rental via enterprise. i was given a nissan versa, extremely slow and extremely ugly. i asked why i didn't get a comparable car and they said nissan requested that i get a nissan rental and that was the only one available. i should get my car back today hopefully. i know now how a dog feels when it gets neutered after driving the versa.

just picked up the car, no issues with it now. did have to bring it back though to have the passenger side window reset since it wouldn't auto up like it used to and have the reverse lockout adjusted because i went to shift into 5th and 6th and went way past the gears. they fixed it in about 30 min though. can't say i see a different in the sound or feel of the clutch but hopefully i won't have any more issues or it will be right back up there.

I know this thread is old but I've just got a used Z with 5000 miles on it and it has the same issue - clearly audible clutch vibration. Sometimes I get a slight grind as I shift up into 2nd too, and my bite point it high like USMCASA describes. I know you guys said it's normal, but I just drove a friend's Z, which has 16000 miles on it and has been tracked repeatedly, and his clutch is A LOT smoother. I'm not happy. My $hit is comparatively clunky. I'm hoping Nissan will agree and do something.

USMCASA - how is your clutch now? Did the noise come back?

I wouldn't worry too much about it. I just got mine last week. Now with 600 miles on it, i hear clunk sound randomly when i shift from 1st to 2nd like many ppl have experienced

Yeah, thanks crazy yank! It's good to be reassured.

Well three months down the line it's not the shifting I have a problem with anymore - I've learned how to manage that and I shift a lot smoother on this gearbox now. But I'm STILL talking to Nissan about the clutch vibration.

They diagnosed it as the throw-out bearing, which they changed along with the clutch cover. That fixed nothing. I now suspect it could be the master cylinder. What else could it be, considering revving the engine up to 3k RPM and back again fixes it temporarily? I'm otherwise lost for answers.

It pisses me off that they deem it 'normal', when I'm now an avid member of Vegas' Z community and NONE of the other guys' 370Zs have that clutch vibration. It pisses me off even more when my Z-owning friends drive my car and say 'woah, that is rough'.

I ADORE my car, but I really wish I didn't have this issue.

2011 Z with 580 miles,Clutch feels weird,noisy when not engaged,noise goes away when clutch pedal pressed down.Normal or not??Never had that before.It almost feels like you can hear the flywheel spinning,and definitely feel vibration on the clutch pedal while pressing down.Vibration and noise goes away after the clutch pedal is fully depressed.
Anything wrong,or it is just normal part of brake in ??!!

Seems like this thread is pretty dead but I have the same thing. It happens when the pedal is up, sometimes is louder than other times. When I press it down, it goes away. If it's normal then fine. But it just sounds terrible!

Anyone has updates?

When I'm at the stop light while depressing my clutch..I just thought my Z was syncing w/ my heart rate..I totally can feel the clutch making that clicking vibration

Same noise with mine, pretty sure it's normal

When your clutch pedal is up or press down when you hear/feel the noise?

Got one for ya'll. In neutral I push the clutch in, I hear and feel a knocking noise. Thing is, it's not constant. It's it's random. I only notice it in neutral...Help...Please?

I notice it when I barely put my foot on the clutch pedal and somewhat in, it is normal.

Clutch Issue
 

Its normal for the 350Z and 370Z due to the clutch pedal two-piece off-set design.

Hopefully, Nissan will re-design the clutch pedal (one-piece) and its attachment point on the firewall.
