WHEN STOPPED AT A FUEL FILLING STATION THE CAR WOULD NOT TAKE IN ANY FUEL FROM THE GAS STATION PUMP AS USUAL. IT REACTS LIKE THE TANK IS FULL BUT IT IS NOT. A VERY SMALL STEADY FLOW OF FUEL WILL FLOW AND FILL WHEN THE NOZZLE IS ENGAGED AS SUCH. THE DANGEROUS PROBLEM IS THAT THE GAS PUMP 'AUTOMATIC STOP' DOES NOT ENGAGE AND FUEL RUNS OUT OF THE FILLER AREA AND DOES NOT STOP UNTIL YOU MANUALLY PULL OUT THE NOZZLE. THE FIAT DEALER SAYS IT COULD BE THE ROLLOVER VALVE AND THEY HAVE SEEN IT HAPPEN BEFORE. THEY WANT TO CHARGE FOR SERVICE/INSPECTION, THEN REPAIRS. SOME DEALERS CHARGE FOR A NEW FUEL TANK @ $1200-1600 AND IT STILL HAPPENS. ONLINE CHATS REGARDING FIAT 500 ALSO DESCRIBE THIS ROLLOVER VALVE PROBLEM. MY CAR HAS 48,000 MILES AND IS A 2012.

A FEW WEEKS AGO, I WOKE UP AND DROVE TO WORK IN THE MORNING. MY FIAT PARKED, I WORKED, EVERYTHING WAS GOOD. 5 HOURS LATER, I GET BACK TO MY CAR TO DRIVE HOME. I START MY ENGINE AND THE DASHBOARD LIGHTS UP SAYING, "HILL START ERROR ... SEE OWNERS MANUAL". I THOUGHT TO MYSELF, "WELP, L GUESS I'LL GO SEE A MECHANIC NOW.". I LIFT THE E-BREAK, PRESS DOWN THE BREAK PEDAL, AND THEN TRY TO MOVE THE CAR INTO REVERSE, BUT IT'S LOCKED IN PARK. I TURN OFF THE CAR. I USE GOOGLE SEARCH ON MY PHONE TO FIND MY FIAT 500 OWNER'S MANUAL ONLINE. I LOOK FOR THE "HILL START ERROR" AND FIND AN OVERRIDE TO GET MY CAR OUT OF PARK AND INTO REVERSE/DRIVE. I RESTART THE CAR. NOW THE DASHBOARD IS COMPLETELY BLANK EXCEPT FOR THE LETTER 'P' IN THE BOTTOM-CENTER OF THE CIRCULAR DASH PANEL. THE LETTER "P" IS BLINKING CONCURRENTLY WITH A BEEP THAT DOES NOT STOP. THERE IS NO MEASURE OF SPEED AND I'M NOT ENTIRELY SURE IF MY LIGHTS ARE WORKING AT THIS POINT. I'M JUST TRYING TO GET THE CAR TO A MECHANIC ABOUT 10 MILES AWAY. I FOUND AN HONEST-FAMILY SPOT AND THE GUY TELLS ME TO LEAVE THE CAR THERE AND HE'LL LOOK AT IT. BREAK LIGHTS WERE OUT AND A SAFETY FEATURE CAUSED IT TO LOCK UP. A COMMON ISSUE IS A BREAK-LIGHT SWITCH WITH THIS CAR, SO... WE REPLACED THE BLS AND DID A FULL DIAGNOSTICS, BUT STILL NO FIX. WE TROUBLESHOOT ALL WEEK AND FOUND THAT A 5-AMP FUSE BLEW OUT IN THE BODY CONTROL MODULE. HE REPLACED THE FUSE AND FOUND THAT IT BURNED OUT AGAIN BECAUSE OF A LOOSE WIRE SOMEWHERE BEHIND THE STEERING WHEEL. IF I RUN THE CAR, THE LOOSE WIRE WILL CAUSE MORE CONNECTIONS TO BURNOUT AND BREAK. THE CAR SHORTS IF WE RUN IT NOW. THE LOOSE WIRE CAUSING THIS SHORT CAUSED MY CAR'S GEARSHIFT TO LOCK UP COMPLETELY, DISABLED MY BREAK LIGHTS, AND LEAD TO SHORTAGES ACROSS THE BOARD. I CAN'T DRIVE IT AT ALL, LET ALONE START IT. I BARELY HAVE 89K ON THIS CAR AND IT'S PRETTY MUCH COOKED.

EA19001 · 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.
