MY CAR WOULDN'T START. THERE IS A SOLID LIGHT WITH KEY ON DASHBOARD WOULD REMAIN LIT. I TRIED ALL METHODS TO POWER ON THE CAR, BUT FAILED. HAD TO GET THE CAR TOWED TO THE NISSAN DEALERSHIP WHERE I WAS TOLD THAT THE CAR REQUIRES A "STEERING LOCK ACTUATOR" REPLACEMENT AND COST RUNS TO APPROXIMATELY $1150. MY CAR IS OUTSIDE OF THE 3 YEAR WARRANTY PERIOD AND HENCE IT CANNOT BE COVERED UNDER WARRANTY. IT SEEMS TO BE A KNOWN ISSUE UPON LOOKING UP ON THE INTERNET. THERE SHOULD BE A RECALL ON THIS VEHICLE FOR THIS PART AS IT IS MALFUNCTIONING MORE THAN USUAL. *TR

KEY INDICATOR LIGHT CAME ON ABOUT A WEEK PRIOR TO THE INCIDENT. MADE 2 PHONE CALLS TO LOCAL NISSAN DEALERSHIPS (ONE IN PORTLAND OR AND ONE IN VANCOUVER, WA) BOTH DEALERSHIPS CLAIMED THEY HAD NO IDEA WHAT WAS GOING ON BUT I SHOULD BRING IT IN FOR A DIAGNOSTIC TEST WHICH RAN AROUND $118 JUST TO LOOK AT. SINCE NOTHING APPEARED WRONG WITH MY CAR I WAITED BECAUSE THE "KEY" LIGHT WOULD GO OFF. IT CAME BACK ON THE DAY I HAD THE INCIDENT AND LEFT ME STRANDED ON MY LUNCH HOUR WITH NO POWER TO START MY CAR. I AGAIN CALLED NISSAN AND THEY WERE NOT SURE WHAT THE PROBLEM WAS. I HAD TO HAVE MY CAR TOWED TO THE NEAREST NISSAN DEALERSHIP WHICH RAN A DIAGNOSTIC TEST. I THEN RECEIVED A PHONE CALL THAT AFTERNOON TO SAY IT WAS MY STEERING LOCK ASSEMBLY AND THE PART WAS EXPENSIVE TO REPLACE. I WAS TOLD THE LABOR WOULD NOT BE MUCH SINCE IT WAS AN EASY FIX. SO THIS PROBLEM TURNED OUT TO THE A $1,200 FIX. I DECIDED TO GO ONLINE TO SEE IF I CAN FIND THIS PART ANY CHEAPER. I THEN RAN ACROSS MANY WEBSITES AND BLOGS WITH NISSAN OWNERS HAVING THE EXACT SAME PROBLEM WITH CAR FROM 2009 TO 2011. APPARENTLY THIS IS NOT SOMETHING NISSAN WAS UNAWARE OF. THE SERVICE REP AT THE DEALERSHIP SAID SHE HAS SEEN OTHER 370Z'S WITH THIS SAME PROBLEM AND JUST HAD ONE TOWED TO THE SERVICE CENTER 2 WEEKS AGO. I FIND IT HARD TO BELIEVE THAT WITH THIS MAY CASES BEING REPORTED AND BLOGGED ABOUT ONLINE WHY NISSAN IS NOT DOING SOMETHING ABOUT THIS. THIS CAN BE A VERY DANGEROUS SITUATION IF LEFT STRANDED IN A CAR THAT WILL NOT START. WHEN YOU TRY TO BE PROACTIVE NISSAN SERVICE CENTERS CLAIM THEY ARE UNAWARE OF THE ISSUE. SOMETHING NEEDS TO BE DONE AND QUICKLY. THIS WILL BE THE LAST NISSAN EVER PURCHASED IF NOT RESOLVED AND REIMBURSED FOR EXPENSE. *TR

DROVE MY CAR TO THE STORE THAT WAS APPROXIMATELY 2 MILES AWAY FROM MY HOME. ON THE WAY THERE, THE CAR WAS OPERATING IN GOOD WORKING CONDITION, AS USUAL. THE KEY INDICATOR LIGHT ON THE DASHBOARD LIT UP BUT THEN QUICKLY DISAPPEARED. AFTER GOING INTO THE STORE, I GOT BACK INTO MY CAR AND TRIED TO START IT UP WITH THE PUSH START BUTTON, BUT NOTHING HAPPENED. SINCE THE KEY INDICATOR LIGHT HAD GONE OFF PREVIOUSLY, I THOUGH THE BATTERY ON MY KEY WAS RUNNING OUT, SO I INSERTED IT IN THE KEY PORT, WHICH INDICATED THE KEY STILL HAD POWER TO IN. I TRIED TO START THE CAR AGAIN BUT NOTHING HAPPENED. THE CAR WAS COMPLETELY DEAD. I THEN CALLED A FAMILY MEMBER TO BRING MY SPARE KEY TO SEE IF THAT WORKED, BUT THE SAME RESULTS HAPPENED. I THEN CALLED A TOW TRUCK, WHO ALMOST WASN'T ABLE TO MOVE MY CAR ONTO THE TRUCK BECAUSE IT WAS COMPLETELY LOCKED UP, AND TOWED MY CAR TO THE NISSAN DEALER. IT WAS THERE THAT THEY TOLD ME THAT THE STEERING LOCK WENT OUT AND COULD NOT FUNCTION WITHOUT IT. *TR

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 CORPORATION 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 RECALL THESE CARS TO GET THEM FIXED PROPERLY. *TR

ON OCTOBER 19, 2012, WHILE DRIVING AND BEGINNING TO STOP, MY BRAKE LIGHT AND MY ABS LIGHT CAME ON. MY BRAKE LIGHT WOULD GO OFF; HOWEVER, THE ABS/TRACTION LIGHT REMAINED ON. I TOOK IT TO THE DEALERSHIP TO HAVE IT LOOKED AT ON OCTOBER 20, 2012 AND WAS TOLD THAT THE BRAKE MASTER CYLINDER WAS LEAKING AND THAT THERE HAD BEEN A RECALL ON THE PART AND THEY WOULD FIX IT, BUT DID NOT KNOW WHEN THEY WOULD GET THE PART AND AS OF OCTOBER 29, 2012, I HAVE NOT BEEN CONTACTED BY THE DEALERSHIP ABOUT THE PART. I AM VERY WORRIED AS I WAS READING ABOUT THE PART AND IT THE INFORMATION OBTAINED STATED THAT ""BRAKE FLUID MAY LEAK FROM THE MASTER CYLINDER," SAID NHTSA IN ITS RECALL SUMMARY OF THE 2009 SENTRA. "IF THE AMOUNT OF BRAKE FLUID IN THE MASTER CYLINDER RESERVOIR DECREASES TO BELOW THE MINIMUM LEVEL, THE BRAKE SYSTEM WARNING INDICATOR WILL ILLUMINATE AS DESIGNED, AND THE BRAKES WILL NOT FUNCTION PROPERLY. IF THE WARNING LAMP IS CONTINUOUSLY IGNORED, ONE OF THE BRAKE CIRCUITS ON THE VEHICLE MAY FAIL, INCREASING STOPPING DISTANCE AND INCREASING THE RISK OF A CRASH." NISSAN HAS YET TO FIX THIS PART AND I BELIEVE AT THIS TIME ARE BEING NEGLIGENT AS FURTHER READING ABOUT THE SITUATION SAID THAT THE BACK BRAKES WILL ALSO START TO WEAR DUE TO CONSTANT PRESSURE BEING PUT ON THEM TO STOP THE VEHICLE BECAUSE OF THIS MALFUNCTION AND I BELIEVE THAT NISSAN AT THIS TIME SHOULD BE RESPONSIBLE FOR REPLACING MY BACK AND FRONT BRAKES SINCE THEY HAVE BEEN NEGLIGENT IN RESPONDING TO THE ISSUE. *TR

1EA21002 · 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.
