I have the same issue.. only happens on hot days in city traffic. sticks right at the point of engagement. I told infiniti about it and they do nothing, and cant replicate the problem. Probably because, when I drop it off it cools down for hours before they drive it. I asked them to change the master or slave cylinder under warranty and they make up some excuse.. I will try the WD40 fix, doesnt hurt and is free.

 

I suspected fluid initially. ( I do drive aggressively.) I can't believe both a MC and Slave Cylinder would go after only 60k miles or at the same time. That wreaks of bad fluid or boiling fluid, especially when the clutch works fine after the car cools down. I suspect a good fluid flush will do the trick. Anyone have a writeup of how to do that?

 

Exactly my thought, even the worst designs of cylinders last longer than that

uh..it was in the link I provided lol

 

Exactly. Free and easy. Everyone should already have a can of WD40 in the house. Try it, if for no other reason than to rule it out. Worked for me.

 

Fluid flush always works for me. Have to do it about once a year or so. I suspect it comes on when you have your A/C since it's out which means your fluid is more prone to boiling. For those that replaced the MC/SC... I'm curious if the problem is fixed since you have to flush the system to replace those parts.

 

My clutch would stick during hot weather.. I didn't know what caused it but I brought it to the dealer and they replace the master cylinder under warranty. So far its been good without any sticking

 

Mine sticks too but I haven't even broken 40k yet?

Ha. Well I just called Infiniti Chantilly and described the problem and the guy told me it wasn't the slave and master cylinder that was the problem but a problem with the pin of the clutch assembly sticking? He said it's not covered under warranty but I don't even know if there's any truth to anything he just told me..

 

Mine started sticking when I only had about 12k on the car. It got really bad at around 15k. That's when I fixed it.

 

had a new clutch and fly put in, and it happened to me when I was in stop in go traffic in the mountains going to lick observatory, never happened again but just then it did. I hope it was just the pedal inside the car.

 

HAH you're a funny guy

 

This is what my fluid looks like. I just have to find time to replace it.

 

what fluid do we use.

 

I have noticed this on here too, and I am one who takes the hands-on approach whenever I can with all my cars. But to each his own lol. I just can't justify throwing a ton of money at a dealership if I can do it myself or with the help of a few buddies. I don't know about you, but I sure don't have a disposable income - I will try the cheap or free methods first before dumping money into it if need be.

Ranger is the man - I have been using his method for years now in any manual car I own. I started it with my '02 Z28 and still do it with the G. I typically do it about every 3-6 months, or whenever I notice a degradation in the performance of the clutch. Its a great cheap way to extend the life of your clutch and the hydraulic system.

 

I had this problem at 10k miles.. Infiniti replaced my clutch pedal
I had this problem at 25k miles.. Infiniti replaced my clutch pedal.
I had this problem at 37k miles.. Infiniti replaced my clutch pedal AND... they gave me a brand spanking new transmission..
I had this problem at 50k miles... HAHAHHAHA fvckers..!! They replaced my slave cylinder..

i have 64k now.. my car driver perfect..

The dealer sux.. They kept telling me that it was the way i driver my car.. I was pissed..
I hate Tustin Infiniti.. They blow..

have you tried to change the clutch fluid? Mine was murky with rust (shows that there was water in the system) and was sticking. Anyways, I changed it out and I can actually power shift now with no issues. before, I was grinding the gears or was locked out.

Just a little fyi. Btw, keep ur clutch fluid changed. The dust from the clutch can seep into the lines. check at every other fuel fill up.
