THE CAR HAS HAD THE RECALL SAFETY RECALL S34 / NHTSA 16V-302 <BR/>MANUAL TRANSAXLE CLUTCH PEDAL PERFORMED BACK AT 30,000 MI. CLEARLY DOSENT FIX THE PRESSURE PLATE ISSUE, AS I'M AN SURE THIS IS WHAT HAPPENED WHEN I WAS GETTING TIRES INSTALLED AND THE STATE INSPECTION AT A NTB SHOP. WHEN YOU HIT THE PEDAL THE CLITCH DOES NOT DISENGAGE, MEANING THE CLUTCH IS ALWAYS ENGAGED AND YOU CANNOT SHIFT GEARS. I PERSONALLY INSPECTED THE CLUTCH SYSTEM FROM THE PEDAL TO THE CLUTCH ARM AND CAN SEE THE CLUTCH DISENGAGEMENT ARM MOVING WHICH LEADS ME TO BELIEVE THAT THE PRESSURE PLATE SPRING IS BROKEN. I HAVE TRIED TO CONTACT THE LOCAL DEALER HERE IN ROANOME, VA TO NO AVAIL. SOUNDS LIKE I WILL BE DOING THE CLUTCH AND RELATED PARTS MYSELF, SO I FIGURED I WOULD GET MY COMPLAINT IN INCASE SOMEONE WANTS TO INSPECT PARTS AS THEY GET REMOVED. THE VEHICLE HAD THIS FAILURE WHILE MOVING SLOWLY IN A SHOP TO BE PUT ON A LIFT TO HAVE TIRES INSTALLED. NO PHOTOS YET, BUT WILL BE GETTING THEM SOON.

SO - I'VE GOT A 2013 500E AND IT STARTED DOING THIS LAST WEEK OR SO. THE RBC, THE ESC, THE ABS, AND EVEN THE HILL ASSIST TRANSIENTLY, AND ONCE OR TWICE EVEN WENT INTO 'PROPULSION SYSTEM SERVICE' ERROR MODE AND WOULDN'T RUN. AFTER A RE-START IT WOULD THEN RUN. EVEN DID THE BATTERY TRICK. NOT SURE IF IT HELPED OR NOT. SO, I DECIDED TO DO THE OBD2 - WITH THE KONNWEI AND THE ALFOBD - FULL PROGRAM - AND IT WAS ABLE TO CLEAR THE CODES AND PULL UP THE ERRORS : U0001, U1201, U1487 - AND EVEN THOUGH IT RECURS AND I FEEL A CLICK AND CHANGE IN BRAKING WHEN THE RBC LIGHT GOES OFF, AND THE ESC LIGHT, AND EVENTUALLY THE ABS LIGHT TOO, AND IT STARTS MAKING FUNNY NOISES FROM THE BRAKES WHEN STOPPED AND PRESSED DEEPLY, BUT I'M ABLE TO CLEAR IT AND GOES BACK TO NORMAL. BUT IT ALWAYS RECURS. ONCE IT WENT AWAY FOR 2 DAYS. ANYWAY - FOUND A TSB ON THIS : NUMBER 08-045-16 - FROM APRIL 22, 2016. AND DESCRIBES PRETTY MUCH ALL THIS AND THE CODES. APPARENTLY THE RBC, AND ABS MODULES NEED REFLASH BY THE DEALER - OR SOMEONE WITH THE WITECH SOFTWARE AND INTERFACE. HERE'S A LINK TO THE PDF ITSELF: HTTPS://STATIC.NHTSA.GOV/ODI/TSBS/2016/SB-10076281-3639.PDF - MY MAIN PROBLEM IS MY LOCAL DEALER IN TUCSON DOES NOT HAVE 500E CERTIFICATION NOR A TECH TO SERVICE THE 500E. I'D HAVE TO DRIVE 100 MILES OR SO UP TO PHOENIX TO GET IT DONE. SO I WOULD NEED TO HAUL IT UP THERE. THIS SUCKS. CALLED THE FCA SUPPORT LINE, THEY SAY THERE'S NOTHING THEY CAN DO, I HAVE TO GET IT THERE.

HELLO, I BELIEVE I NEED AN ATTORNEY AND LEGAL ADVICE. I HAVE A DEFECTIVE CAR THAT SHOWS ON THE FIAT DEALERSHIP WEBSITE AS A RECALL. THE YEAR MAKE AND MODEL OF MY CAR HAS A RECALL (2/2013 RECALL N09 REPROGRAM POWERTRAIN CONTROL MODULE) I HAVE HAVE BEEN REPORTED MY ISSUE TO FIAT DEALERSHIP FOR THE LAST THREE YEARS AND WAS TOLD THAT BASED ON MY VIN NUMBER I DO NOT HAVE A RECALL. WHEN I SERVICE MY CAR AT DEALERSHIP THEY JUST TURN OFF MY ENGINE LIGHT. I HAVE NOT BEEN ABLE TO PASS INSPECTION OF MY VEHICLE IN OVER TWO YEARS. MY MECHANIC EXPLAINED TO ME THAT I HAVE A RECALL AND HE CANNOT PASS INSPECTION. I AM AFRAID TO DRIVE MY CAR, BUT CANNOT SELL IT OR TRADE IT IN DIE TO THE ENGINE LIGHT ERROR. I HAVE A RECORD OF ALL OF MY RECEIPTS. THIS STARTED IN JANUARY 2018. I BELIEVE THAT I SHOULD FILE CHARGES AGAINST FIAT AND WOULD NEED LEGAL ADVISE. THANK YOU.

LATE IN MARCH 2019 I WENT OUT TO MY CAR AT WORK TO DRIVE HOME (HOUR COMMUTE VIA MOSTLY HIGHWAY ROADS). WHEN I PUT MY CAR IN REVERSE, THE STICK SHIFT DIDN'T SEEM RIGHT. WHEN I ATTEMPTED TO PUT THE CAR IN 1ST GEAR IT WOULD NOT GO. AT THAT POINT I ONLY HAD 2ND AND 4TH GEAR AVAILABLE (3RD AND 5TH WOULD ALSO NOT WORK). I DROVE HOME AT LOWER SPEEDS DUE TO NOT BEING ABLE TO SHIFT INTO 5TH GEAR. I IMMEDIATELY DROPPED THE CAR OFF AT A TIRES PLUS IN ATHENS, GA WHERE I LIVE. I THOUGHT MY CLUTCH HAD GONE OUT AS BY THE TIME I GOT THERE I COULD NO LONGER SHIFT GEARS AT ALL (STUCK IN 2ND). OVER THE NEXT FEW DAYS, TIRE PLUS TOLD ME THEY THOUGHT IT WAS MY TRANSMISSION AND THEY ADVISED ME TO LOOK INTO GETTING IT FIXED ELSEWHERE DUE TO THEM NOT BEING ABLE TO DO THE WORK. ONE OF THE TECHS THERE DID MENTION THE POSSIBILITY THAT IT COULD BE THE SHIFTER CABLE AND THAT IT MIGHT BE WORTH IT TO TAKE IT TO A CHRYSLER DEALERSHIP TO VERIFY. I THEN PICKED THE CAR UP AND DELICATELY DROVE IT TO ATHENS DODGE CHRYSLER JEEP ON 4/1/19. THEY RAN DIAGNOSTICS AND DETERMINED SURE ENOUGH- IT WAS A BROKEN SHIFT CABLE (INVOICE ATTACHED SAYS THEY "REPLACED SHIFTER CABLES"). I RECENTLY BECAME AWARE OF A RECALL (VIA MAIL?) ON FIATS IN THE AGE RANGE OF MY VEHICLE (NHTSA CAMPAIGN ID: 19V817000 AND CHRYSLER RECALL #VB4) AND UPON LOOKING INTO IT ON BOTH THE NHTSA AND FIAT SITES, FOR WHATEVER REASON MY CAR WASN'T UNDER THE RECALL. I CALLED CHRYSLER DIRECTLY AT 800-853-1403 AND THE REPRESENTATIVE I SPOKE TO SAID SHE DIDN'T UNDERSTAND WHY MY VIN # WASN'T ONE THAT WAS RECALLED BASED ON THE NATURE OF THE MALFUNCTION AND SUBSEQUENT REPAIR LAST APRIL. SHE SAID THAT PEOPLE CALL ALL THE TIME HAVING ALREADY HAD THE WORK COMPLETED PRIOR TO THE OFFICIAL RECALL SEEKING (AND RECEIVING) REIMBURSEMENT. SHE SUGGESTED GOING TO THIS SITE TO REQUEST THAT MY SPECIFIC VEHICLE BE ADDED TO THE RECALL SO THAT I COULD BE REIMBURSED, AS WELL.

Opened Apr 19, 2019 · Closed Sep 19, 2024
Status: closed (inferred from source dates) · Air Bags: Air Bag/restraint Control Module
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications. The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU. In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment. FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle. Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW. These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes. An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time. In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU. This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners. Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW. The risk associated with the ASIC is equally shared among all OEMS involved in the investigation. The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage. There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation. The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU. If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC. Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC. All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled. In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024. With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.
