HI, I HAVE HAD SEVERAL ISSUES WITH MY CAR WHICH HAVE HAD SEVERAL ATTEMPTS TO FIX. SAFETY CONCERNS REGARDING THE CRUISE CONTROL LOCKING UP ON MY VEHICLE, CONVERTIBLE TOP STILL NOT ADJUSTING AND BLOCKING LINE OF SIGHT IN THE BACK SO YOU CANNOT SEE WHAT IS BEHIND YOU WHILE DRIVING, AND START UP ISSUES WITH CAR NOT ALWAYS STARTING UP CORRECTLY, HAVING MISFIRES. THE CAR HAS ONLY BEEN WORKED ON THE DEALERSHIP WHERE I PURCHASED THE VEHICLE AT THE FIAT OF VAN NUYS, CA. THE CAR HAS BEEN WORKED ON SEVERAL TIMES SINCE I FIRST PURCHASED IT BACK IN JAN OF 2013. I AM SEEKING OUT ANY HELP NECESSARY AS I HAVE HAD THESE SAFETY CONCERNS SINCE I FIRST GOT THE CAR TO NOW AND I AM FEEL VERY UNSAFE WITH THE WORK THAT HAS BEEN DONE AS WELL AS MY OWN SAFETY AS WELL AS OTHERS. THANK YOU, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).'*JB

CAR IS VERY YOUNG, 24, 781 MILES AND TURNED IN BY PRIOR OWNER WITH 22,400'S MILES. AFTER CAR WAS SOLD WITH A RECALL, IT WAS NOTED IT ALSO SUFFERS FROM OIL LEAKING FROM THE REAR MAIN TRANSMITTION, PER MECHANIC IT AFFECTS BOTH THE TRANSMITION AND THE MOTOR, AND COULD CAUSE DEATH IF CAR RAN OUT OF OIL. LEAK PER SEVERAL INDEPENDENT MECHANICS IS TOO SOON FOR A FIAT WITH SO LITTLE MILES, AND A CAR THAT STILL OWNS THE ORIGINAL TIRES, WIPERS, AND STILL HAS THE SMELL FROM WHEN IT WAS NEW. CAR BY PRIOR OWNER WAS FOR VACATION, BUT CAR NOW LEAKS AND IT SEEMS MANY VEHICLES THIS YEAR MODEL HAVE THE SAME ISSUE PER BLOGS AND FIAT COMPLAINTS BLOGS, UNFORTUNATELY THE DEALER WONT FIX THE PROBLEM AND MECHANICS ARE IN SHOCK CAR WAS SOLD WITH A RECALL AND WHEN IT WAS SERVICED THEY TOO REFUSED TO WORK ON THE SEAL WAITING FOR THE CAR TO GO THROUGH THE BANK FIRST & HOPE FOR A WARRANTY TO PAY FOR THE LABOR AND PART, EVEN AFTER I OFFERED TO PAY FOR THE PART WHILE THEY WERE ALREADY IN THE CAR CHANGING. HOWERVER, THEY FAILED TO INFORM ME ABOUT THE ISSUE, UNTIL I GOT HOME WITH THE CAR. ISSUE IS LIFE THREATENING BY MECHANICS WORDS, AND ALL 4 DIFFERENT SHOPS DEMANDED I EITHER RETURN THE CAR TO THE DEALER OR DEMAND THEY FIX IT BEFORE I WOULD END UP DEAD OR IN AN ACCIDENT ON THE HIGHWAY. THIS ISSUE SHOULD NOT BE PART OF A YOUNG CAR, IT SHOULD NOT BE LEAKING FROM A SEAL, PARTICULARLY THE TRANSMITION MAIN REAR SEAL, WHICH PER MECHANIC IT TOO AFFECTS THE MOTOR AND THE T RANSMISSION ABILITY TO FUNCTION ON A MANUAL VEHICLE.

WHAT UPDATE COULD THEY HAVE MY VEHICLE RECALL HAS NOT BEEN FIXED IN A TIMELY MANNER. MY VEHICLE HAS NOT BEEN FIXED AT ALL. THE TRUTH IS THERE ARE VERY FEW MECHANICS IN THE UNITED STATES OF AMERICA CAPABLE OF FIXING A FIAT BECAUSE OF THE UNIQUE DESIGN MOST MECHANICS DON'T HAVE THE PROPER TRAINING FOR THIS PARTICULAR DESIGN OF VEHICLE NOR DO THEY HAVE THE CORRECT TOOLS THE VEHICLE IS DESIGNED USING A EUROPEAN METRIC SYSTEM IN ORDER TO BRING THE VEHICLE TO SAFETY STANDARDS FIAT MECHANICS NEED THE PROPER TRAINING AND TOOLS! BOTTOM LINE MY RECALL HAS NOT BEEN FIXED!

DURING A NORMAL OIL CHANGE AROUND 37,000 MILES THE DEALER INFORMED ME THE REAR MAIN SEAL ON MY FIAT 500 WENT OUT AND THAT THE REPAIRS WOULD BE UPWARDS OF $1,000. I RESEARCHED ONLINE AND FOUND OUT MANY FIAT 500S MANUFACTURED FROM 2012 HAD THIS ISSUE OCCUR AT VERY LOW MILES. THE DEALER INFORMED ME MY 4 YEAR/50,000 MILE WARRANTY HAD RUN OUT IN JUNE 2016 AND THAT I MUST PAY THE COSTS. I ENDED UP PAYING OVER $1,100.

I KNOW FOR FACT THAT THIS VEHICLE DID NOT HAVE THIS SOFTWARE AVAILABLE FOR THE 2012 THAT SOFTWARE WAS ONLY USED ON VEHICLES IN 2010 AND FIAT DIDN'T HAVE 5 DEALERSHIPS IN THE ENTIRE UNITED STATES OF AMERICA IF THEY HAD ONE IN 2010. THE SOFTWARE FOLLOW ME WAS ONLY ON FOREIGN FIAT CARS ALSO I KEEP GETTING A LIGHT SAYING TIRE PRESSURE MONITORING IS UNAVAILABLE! WHEN I CALL FIAT I GET POOR CUSTOMER SERVICE I EVEN HAD A LADY CALL ME A CRIMINAL FOR GIVING MY WHOLE VIN # SHE STATED SHE NEEDED TO "MAKE SURE YOU DIDN'T JUST WALK BY THE VEHICLE AND GIVE A VIN # THAT YOU GOT FROM SOMETHING ELSE." I BELIEVE FIAT IS HACKING IN TO VEHICLES IN AN EFFORT TO GET CUSTOMERS TO BRING THE VEHICLES TO KEN GRAFF FIAT 198 E 500 SOUTH SALT LAKE CITY UTAH 84111. I REFUSE TO GO BACK TO THIS CAR DEALERSHIP BECAUSE THEY SEEM TO BE MORE CONCERNED WHITH WHEN AND WHERE I PURCHASED THE CAR AND IF I HAD A CAR NOTE FIAT TRIED TO PRETEND THAT THEY DIDNT HAVE PARTS AVALIBLE AND TO GET ME TO DRIVE A LOANER CAR. I OWN MY CAR! I DONT HAVE A CAR NOTE AND IT SEEMS TO BE ALOT OF FUNNY BUSINESS GOING ON IN REGARDS KEN GRAFF AND CHYSLER FIAT AURBUN HILLS REFUSES TO HELP WITH THE MATTER ALSO THE MILEGAGE SEEMS TO HAVE SLOWED DOWN A WHOLE LOT FOR EXAMPLE IF I DRIVE 20 MILES IT WILL ONLY SHOW 15.

1EA19001 · Electrical Overstress
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.
