CLUTCH SLAVE CYLINDER WENT OUT AT AROUND 40K MILES. AFTER DOING SOME RESEARCH, THIS IS A KNOWN PROBLEM WITH MANY OTHER 370 Z'S. I AM NOW WORRIED THAT I WILL NEED A THIRD CSC.

WHILE DRIVING DOWN THE HIGHWAY IN 6TH GEAR FOR ABOUT 30 MINUTES TO AN HOUR, THE CLUTCH PEDAL BEGINS FEELING VERY SOFT AND BEGINS STICKING TO THE FLOOR TO THE POINT WHERE IT IS NECESSARY TO PULL IT BACK UP WITH MY FOOT. ON TEXAS HIGHWAYS, THIS IS EXTREMELY DANGEROUS IF I AM UNABLE TO ENGAGE A GEAR WHILE DRIVING IN HEAVY TRAFFIC, ESPECIALLY SINCE A LOT OF HIGHWAYS ARE UNDER CONSTRUCTION WITH NO SHOULDER TO SAFELY PULL OVER TO. THE PART AT FAULT IS A POORLY CONSTRUCTED CONCENTRIC SLAVE CYLINDER. THIS IS A PIECE OF PLASTIC THAT IS EXTREMELY PRONE TO FAILURE. IT SHOULD HAVE NEVER BEEN CONSTRUCTED FROM PLASTIC. NISSAN ALSO REFUSES TO OBEY THEIR 5 YEAR, 60,000 MILE POWERTRAIN WARRANTY TO FIX THIS ISSUE. (THE ONLY CLUTCH PART LISTED AS "NOT COVERED" IS THE WEARABLE CLUTCH DISC ITSELF). THEY ALSO REFUSE TO ACKNOWLEDGE THAT THIS IS A COMMON ISSUE. I'M ATTACHING A SCREENSHOT OF OVER 100 370Z FORUM MEMBERS WHO HAVE REPORTED THIS ISSUE AS WELL. THIS IS CLEARLY A PROBLEM THAT NEEDS ADDRESSED, BUT NISSAN REFUSES TO ACKNOWLEDGE THE SAFETY OF THEIR LOYAL CUSTOMERS.

TAKATA RECALL. I FIRST OCCURRED A PROBLEM WITH THE Z ON MY WEDDING DAY. MY CLUTCH DROPPED TO THE FLOOR AND WE COULDN'T GET THE CAR IN GEAR. WE WERE PUT IN THE MIDDLE OF THE MOUNTAINS WITH NO WAY TO CALL A TOW TRUCK SO WE DID OUR BEST TO MAKE IT TO THE CLOSEST NISSAN DEALER. ON THE WAY WE CAME TO A FOUR WAY RED LIGHT AND COULDN'T SHIFT TO A LOW ENOUGH GEAR TO GET TO CAR TO SLOW DOWN, A SEMI WAS TRAVELING ABOUT 60 MPH RIGHT AT US, WE SWERVED INTO THE EMERGENCY ON AND THE TRUCK TO BARELY MISSED US. AFTER THAT MY HUSBAND FOUND OUT FROM A MECHANIC THAT HE SHOULD BLEED THE CLUTCH SO HE DID AND THE CLUTCH WAS NORMAL AGAIN. BESIDES THAT THE CAR HAS HAD ONLY ONE OTHER OCCURRENCE WITH THE CLUTCH. I AM PETRIFIED TO DRIVE MY CAR AFTER THAT SITUATION BUT I HAVE NO CHOICE CONSIDERING I SPEND MOST OF MY PAYCHECK JUST TO PAY FOR THE ONE THING THAT WILL PROBABLY SEND ME TO MY GRAVE. THIS IS A VERY SERIOUS PROBLEM AND SHOULD BE FIXED! NOW TO MENTION THIS MORNING... I WOKE UP TO GO TO WORK AND WENT TO START MY CAR WHEN MY CAR WOULDN'T START DUE TO A STEERING LOCK MALFUNCTION AND WILL PROBABLY END UP HAVING TO TAKE IT TO A DEALERSHIP IF MY RESEARCH DOESN'T WORK OUT AS PLANNED. THE BRAKE LIGHT COMES ON WHEN I PUSH THE CLUTCH... THE TRACTION CONTROL LIGHT COMES ON AND STAYS ON FOR LONG PERIODS. THIS CAR IS GOING TO HURT SOMEONE BAD! WORRIED ABOUT THE PEOPLE DRINKING AND DRIVING? YOU SHOULD BE WORRIED ABOUT THE PEOPLE DRIVING A NISSAN 370Z !!!! SO FRUSTRATED!

WHILE DRIVING HOME FROM TEXAS MY CLUTCH STARTED TO WEAKEN AND EVENTUALLY STUCK TO THE FLOOR WHILE I WAS TRAVELING APPROXIMATELY 70 MPH. UNDERSTANDING THAT MY CAR HAD A PROBLEM THAT WAS LIKELY TO LEAVE ME STRANDED, I CONTINUED TO TRAVEL AT 70 TO 75 MPH FROM JACKSON, MISSISSIPPI TO BIRMINGHAM, ALABAMA WITHOUT STOPPING. WHEN I ARRIVED AT THE END OF THE OFF RAMP, I COULD NOT GET THE CAR INTO 1ST GEAR SO I COULD CONTINUE ON HOME. AFTER BEING STRANDED FOR ABOUT 30 MINUTES, I EVENTUALLY GOT THE CAR INTO FIRST GEAR. I HAD TO DRIVE FROM THE EXIT TO MY HOME IN FIRST GEAR. WHEN I GOT TO MY HOUSE I HAD TO USE THE STARTER TO GET MY CAR INTO THE GARAGE. THE TRIP FROM JACKSON TO BIRMINGHAM WAS EXCEPTIONALLY DANGEROUS AND THERE WAS MANY OPPORTUNITIES FOR A TRAGEDY FOR EXAMPLE: (1) NOT BEING ABLE TO REACT PROPERLY IN TRAFFIC, (2) NOT BEING ABLE TO REACT PROPERLY TO CONSTRUCTION ZONES, (3) NOT BEING ABLE TO REACT PROPERLY TO CITY SPEED ZONES, ET CETERA. GIVEN THAT THIS ISSUE CAME ON QUICKLY, A DANGEROUS SITUATION PRESENTED ITSELF IN HEAVY FAST MOVING TRAFFIC WHEN I COULD NOT PROPERLY CHANGE GEARS WHEN DOWN-SHIFTING. DUE TO MY DELAYED RESPONSE TRYING TO GET MY CAR INTO GEAR, I WAS ALMOST HIT FROM BEHIND WHICH CAUSED OTHER NEARBY CARS TO HAVE TO REACT TO THE SITUATION AS WELL. FORTUNATELY EVERYONE AROUND ME AT THE TIME OF FINAL FAILURE WAS PAYING ATTENTION. TAKING A LOOK AT THE HISTORY OF THIS ISSUE, IT SEEMS TO HAVE CARRIED FROM THE 350Z TO THE 370Z WHICH STARTS IN 2002 AND CONTINUES YEAR TO DATE. BASED ON RESEARCH IN FORUMS, THIS FAILURE TAKES PLACE AT AN AVERAGE OF 25,000 MILES AND CONTINUES TO REOCCUR AFTER REPLACEMENT AT THE SAME INTERVAL. IT IS A MATTER OF TIME BEFORE THIS FAILURE CAUSES A DEATH, BUT THEN AGAIN, IF SOMEONE DIES THEY WILL HARDLY BE ABLE TO REPORT THE PROBLEM. PLEASE LOOK INTO THIS ISSUE AND CONSIDER BOTH THE 350Z AND THE 370Z--WHICH HAS INHERITED THE ISSUE.

WHEN I ENTERED MY CAR TO LEAVE IN THE MORNING MY CLUTCH PEDAL HAD NEXT TO NO PRESSURE WHEN DEPRESSED. THE CLUTCH WOULD ONLY DISENGAGE WITH APPROXIMATELY HALF AN INCH BEFORE REACHING THE FLOOR. I IMMEDIATELY SHUT MY CAR OFF AND CALLED THE NISSAN SERVICE CENTER. I WAS ADVISED TO BRING MY CAR IN. AFTER WAITING FOR TRAFFIC TO SUBSIDE I NERVOUSLY DROVE MY CAR TO THE SERVICE CENTER WITHOUT INCIDENT. WHILE DRIVING, I NOTED THAT THE PRESSURE IN MY CLUTCH PEDAL WAS GETTING WORSE. HAD THIS STARTED WHILE DRIVING I COULD HAVE BEEN SEVERELY INJURED, OR WORSE. THE NISSAN SERVICE CENTER DETERMINED THAT THE FAULTY PART WAS THE CLUTCH CONCENTRIC SLAVE CYLINDER. THIS PART IS SOMEHOW NOT COVERED IN MY VEHICLE'S POWER TRAIN WARRANTY, EVEN THROUGH IT IS AN INTERNAL PART OF THE TRANSMISSION. I AM FORTUNATE THAT THIS DID NOT HAPPEN WHILE I WAS DRIVING MY CAR, AS THINGS COULD HAVE BEEN MUCH WORSE. NISSAN HAS BEEN RELUCTANT TO EVEN ACKNOWLEDGE THAT THIS HAS BEEN AN ISSUE WITH THIS VEHICLE, EVEN THOUGH THERE ARE MANY COMPLAINTS ABOUT THIS FAILURE, WHICH IS EASILY DISCOVERED WHEN DOING INVESTIGATION ONLINE.

SINCE I COULD NOT PUT IT IN THE NEXT GEAR, I PUT IT IN NEUTRAL AND PUSHED IT BACK INTO MY GARAGE. MY MECHANIC SAID IT WAS THE CLUTCH SLAVE CYLINDER. HE ALSO SAID THERE WAS A LOT OF BREAK FLUID IN THE TRANSMISSION COMING FROM THE CSC. I WENT ON 370Z PAGES AND THIS COMPLAINT IS ALL OVER THE PLACE. THERE ARE NUMEROUS FORUMS TO THIS ISSUE. LUCKILY I WAS NOT DRIVING ON THE FREEWAY OR I COULD HAVE CAUSED A MAJOR ACCIDENT. IF THIS ISSUE HAS BEEN HAPPENING FOR A LONG TIME TO HUNDREDS IF NOT THOUSANDS OF CARS FOR THIS MAKE AND MODEL, WHY HAS THIS NOT BEEN FIXED? BILL WAS AROUND $1000.00. HAVEN'T HAD ANY ISSUES SINCE REPLACING THE CSC BUT ONLY HAVE PUT ABOUT 4 THOUSAND MILES ON IT SINCE.

I WENT OUT TO START MY CAR FOR A DRIVE ON 06/21/15. AS I WAS REACHING FOR THE CLUTCH PEDAL WITH MY FOOT TO START THE ENGINE, I FOUND THE CLUTCH PEDAL HAD ALREADY SUNK HALF WAY TO THE FLOORBOARD BEFORE MY FOOT CAME IN CONTACT WITH IT. I HAD TO REACH IN FURTHER ALMOST COMPLETELY EXTENDING MY LEG IN ORDER TO MAKE CONTACT WITH THE PEDAL. UPON CHECKING THE CLUTCH FLUID I WAS SURPRISED TO FIND SOME OF MY FLUID LEVEL WAS HALF EMPTY HAD AND LOOKED VERY DARK. THERE WAS BLACK DEBRIS SITTING UNDER THE FLUID RESERVOIR. MY FLUID LEVEL WAS AT THE MAX WHEN I LAST CHECKED IT TWO WEEKS PRIOR, SO BETWEEN THAT TIME SOME FLUID HAD LEAKED OUT. I FILLED UP WITH SOME BRAKE FLUID AND PUMPED THE PEDAL SEVERAL TIMES, WHICH HELPED REGAINS SOME PRESSURE IN MY CLUTCH PEDAL BUT NOT COMPLETELY, THERE IS STILL SOME SLACK IN THE PEDAL TRAVEL. I IMMEDIATELY WENT ONLINE TO RESEARCH THE PROBLEM. I RAN ACROSS COUNTLESS COMPLAINTS FROM OTHER Z OWNERS HAVING THE SAME ISSUES WITH THEIR FACTORY CLUTCH SLAVE CYLINDER (CSC) & MASTER SLAVE CYLINDER. MANY REPORTED THEIR CLUTCH PEDAL "DIVING" AND WOULD NOT RETURN DURING DRIVING. UNLIKE ME, MOST OF THEM WERE LEFT STRANDED ON THE SIDE OF THE ROADS DUE TO NOT BEING ABLE TO OPERATE THE CLUTCH AFTER THE PEDAL LOSS PRESSURE AND DIVES TO THE FLOOR. FURTHERMORE, PEOPLE HAVE REPORTED THEIR FACTORY CSC FAILURES SINCE THE NISSAN 350Z WERE STILL IN PRODUCTION (2002-2009). NISSAN NORTH AMERICA IS FULLY AWARE OF THIS DEFECTS IN THEIR CLUTCH ASSEMBLY. IN 2008, NISSAN ISSUED A RECALL TO 350Z OWNERS TO REPLACE THEIR DEFECTIVE CSC. I AM APPALLED THAT THEY (NISSAN) CONTINUED TO RELY ON THE SAME DEFECTIVE PARTS ON THEIR NISSAN 370Z. CURRENTLY, NISSAN HAS NOT ADDRESS THIS PROBLEM ON THEIR 370Z MODEL, NOR ARE THEY HONORING ANY WARRANTY CLAIMS REGARDING THIS ISSUE. THIS IS A REAL CONCERN AS IT POSSES A SERIOUS SAFETY THREATS TO ALL Z'S EQUIPPED WITH MANUAL TRANSMISSION. UPDATED 09/01/2015*LJ

I PURCHASED THE 2011 NISSAN 370Z NISMO WITH 30,000 MILES FROM A NISSAN DEALERSHIP AND AFTER 2500 MILES OF DRIVING I HAD THIS ISSUE WITH THE CLUTCH. I WAS DRIVING AND THE CLUTCH PEDAL WENT TO THE FLOOR AND WOULD NOT COME BACK UP. AFTER PULLING OVER I CHECKED AND SAW THAT THE CLUTCH FLUID RESERVOIR WAS COMPLETELY EMPTY. I KNOW THE FLUID WAS FULL AND CLEAN WHEN I GOT THE CAR BECAUSE WE LOOKED AT ALL OF THE FLUIDS AT THE TIME OF PURCHASE. I RAN TO A GAS STATION TO GET SOME BRAKE FLUID TO FILL IT UP AND DROVE HOME. I DID NOT TOUCH THE CAR UNTIL I WAS ABLE TO DRIVE IT TO THE DEALERSHIP THAT WEEKEND. THE DEALERSHIP TECHS WERE UNABLE TO FIND ANY KIND OF LEAK IN THE CLUTCH LINE, SLAVE CYLINDER, OR MASTER CYLINDER AND RECOMMENDED I HAVE THEM FLUSH THE FLUID WITH NEW "GTR BRAKE FLUID". AS OF RIGHT NOW THAT HAS BEEN DONE (NOT COVERED BY MY DRIVE TRAIN WARRANTY), BUT I'M NOT SURE HOW NEW FLUID WILL STOP A LEAK. I DON'T DRIVE THE CAR AS MUCH AND HAVE BEEN KEEPING A CLOSE EYE ON THE FLUIDS.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
