Clutch Pedal/linkage Problems of Nissan 370Z - part 2

Premature failure of the concentric slave/master cylinder. Causes the clutch pedal to sink down and not come back up. Very dangerous when clutch randomly engages because of this. Enthusiasts have diagnosed the problem is due to plastic components used in the cylinders. There is already a aftermarket slave cylinder that fixes this problem by using metal components.

I have a 2013 370z with a manual transmission. On 4-9-2014 I was traveling 45 mph on expressway. I began slowing for light and downshifting from 6th gear to 5th and 4th. When I shifted into 4th gear the clutch pedal did not return to it's normal position and stayed about 1/2 way down towards the floor of the vehicle. I then shifted into 3rd gear and the clutch pedal went completely to the floor and remained fully depressed and did not return to it's upright position. I had no clutch function at this point. I muscled the car into neutral to avoid stalling the engine and came to a stop at the red light. I was unable to place the car in gear when the light turned green. I ground the gears and got the vehicle into 2nd gear, got off the expressway and into a nearby parking lot. I called a tow and had the vehicle towed to the nearest Nissan dealership. I was informed that the hydraulically actuated clutch fluid had overheated and failed causing the hydraulic actuation of the clutch to fail. The dealership flushed the hydraulic system and replaced the hydraulic fluid with higher temperature fluid from a gtr per Nissan service bulletin ntb13-026a. The vehicle seems to be operating properly at this point but I was very concerned and could have easily been involved in a accident as I was sitting at a green light on an expressway with a disabled vehicle. Nissan is obviously aware that standard duty hydraulic fluid in 370z's can overheat and fail as noted in their service bulletin. I feel that hydraulically actuated manual transmission 370z's should be filled with high temperature hydraulic fluid from the factory.

Base model. Manual transmission. Stock - no aftermarket enhancements. On freeway attempting to decelerate (shifting down from 5th to 4th) clutch pedal "disappears" into the floor board. This marks the beginning of problems with the clutch pedal having a mind of it's own. Transmission hard to shift 1st and 2nd gear. Barely made it into dealership next morning. Dealership only has a TSB to replace the transmission fluid. Fluid changed, drove away. Problem returned 2/7/14 and continued to get worse for next few days. Returned vehicle to Nissan dealership on 2/12/14 where it is waiting for parts (clutch slave cylinder). Nissan corporaation TSB recommends replacement of clutch master cylinder at same time of clutch slave cylinder, however, dealership has not made mention of this. Part supposedly won't arrive until 3/3/14. After further research, the 370z suffers from this clutch slave/master cylinder issue on a consistent basis. Current car has only 7,600 miles. This is covered under 3/36 warranty, however, the issue is dangerous because it can happen so suddenly and I would reiterate that this problem is apparently common. Who waits 3 weeks for a clutch part unless Nissan corporations is so back-ordered on 370z clutch components that Nissan cannot keep up with this repair demand? Nissan needs to re-engineer this clutch master/slave cylinder issue and reacall these cars to get them fixed properly.

While driving the car under normal driving conditions, the clutch pedal would not come up from the floor after coming to a stop at a stop sign. After letting the car sit for approx. 90 minutes, the clutch pedal operation appeared to return to normal. I went online to research this problem and found this. . . Per Nissan: subject: sb 370z coupe and roadster; clutch pedal does not return to rest position summary of ntb13026: if you confirm: the clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor or the customer states the clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor there are no leaks in the clutch hydraulic system*. Action: change the clutch hydraulic system fluid with gt-r r35 special brake fluid (see parts information). - refer to service procedure for bleeding procedure. See this bulletin for further detail. I took the car to a local Nissan dealership and they were able to replicate the problem. Their solution was to replace the clutch fluid withe the gtr r35 special brake fluid as described in the service bulletin. However, I've read multiple reports that this "fix" only holds up temporarily and, that eventually the csc (concentric slave cylinder) and/or the cmc (clutch master cylinder) fail. Many, many 370z owners have had to have both the csc & cmc replaced. The Nissan dealership where I took my car said they would replace those parts but, only if I experience the clutch pedal failure again. My feeling is that they should've replaced these parts when they replaced the fluid since they're aware that merely changing the fluid is not really fixing the problem since the csc & cmc so often fail even after the fluids have been changed.

This problem of the clutch sticking has been an ongoing problem since I purchased the vehicle. I don't drive the car that often but when I do the clutch pedal does not come up once pushed to the floor. In order for the clutch pedal to return to the up position I have to pull it up with my left foot and this have become a hazard driving. The car currently have 42,242 miles.

Part has failed 3 times . (1)@65k miles. Clutch slave cylinder failure . While coming to a stop I push clutch pedal in and it didnt release ,and addition the clutch did not disengage creating a stopping issue. Could not get out of gear, causing the car to lunge forward when forcing to a stop. Stuck in traffic. (2)@77k miles. Clutch slave cylinder failure . While coming to a 4 way stop during rush hour the clutch pedal when in and didnt come out. Unable to change gears. Car stuck in traffic. (3)@83k miles. Clutch slave cylinder failure . Pulling into garage I go to push the clutch in and the car keeps moving, almost running into back walll of garage. Clutch pedal went in and didnt come back out. Clutch slave cylinder failure again. Having that same part fail with increased frequency its certainly isnt the way I drive my car. Oem part lasted 65k than oem part lasted 12k than oem part lasted 6500 miles. I love this car so much I bought a car lift to replace this part myself. Dealer charges over $1100 to replace a 75 dollar part. But it is very dangerous to have this part fail. I have been very lucky that no person was walking by the front/rear of my car while I push in the clutch pedal or had it failed while trying to park. This last time I noticed a shudder from the clutch pedal prior to part failure.

At 40,000 miles my clutch slave cylinder failed while driving. My clutch pedal went all the way to the floor of the car and would not come back up. Dealer attempted to say this was a wear and tear part, but my extended warranty had to cover the cost. . Read more...

Engine was replaced at 30,295 miles (due to excessive oil use) on 5/16/12. Upon return and on may 17, 2012, while driving the car, the clutch pedal would remain at the base of the floor of the vehicle. After driving, the clutch pedal would eventually came back to it's normal position. Approximately 2 months later, this re-occurred while driving the vehicle again, but this time, the vehicle would not go into 3rd gear, (leaving me stranded in traffic). . . Everything eventually went back to normal. At 38,607, the clutch pedal once again remained on the floor board & on 1/26/13, the dealer diagnosed and replaced the failed clutch slave cylinder & master cylinder. On 5/27/13, at 45,769 mi, the vehicle was taken back to the dealer for the same problem (clutch pedal remained on floor)-dealer stated-couldn't duplicate the concern. On 2/05/14, approx. 52,000 mi, the vehicle was taken to the shop after the clutch pedal remained on the floor and would not shift into gear (once again stranding me in traffic). This part (slave cylinder) is a common failure in the 350z, g37, 370z vehicles (as indicated in various forums) because of it's poor design and has a history of failure. There are no previous warnings given and can render the car helpless while driving in traffic.

I have a 2009 370z. It is daily driven (no clutch dumping, burn out, track, racing, etc. ). The clutch is oem. At 16,158 miles I was leaving work. I was getting ready to pull out of the parking lot when the clutch pedal sunk to the floor. The more I press down, the more pressure was lost. The dealership diagnosed the problem as a failed concentric slave cylinder. This is probably the same part that is used in the '07+ 350z with similar issues. Thankfully this problem occurred in the parking lot. The pedal sinking to the floor was sudden and without warning.
