ON THE DAY OF FEB. 24 2015 ME AND MY WIFE WERE IN THE DRIVE-THRU AT STAR-BUCK. WHILE WE WERE IN LINE TO GET COFFEE WE SMELL THIS BAD BURNING SMELL. I THOUGHT IT WAS FROM SOME WHERE IN THE AREA, I EVEN ASK THE STAR-BUCK CLERK WHATS THAT SMELL, HIS REPLY WAS THIS IS THE FIRST TIME SMELLING IT. AS WE PULLED OFF FROM STAR-BUCKS I NOTICED WHITE SMOKE COMING FROM UNDER THE HOOD AND MAKING ITS WAY INTO THE CABIN OF THE VEHICLE. CALLED THE FIAT DEALERSHIP AS IT WAS HAPPENING, THEY SUGGEST ME TO BRING FIAT IN, SO I DID. FIAT VERIFIED THE PROBLEM AND STATED THIS.( VERIFIED CLUTCH BURNING TYPE SMELL UNDER HOOD. INSPECT AND FOUND NO LEAK AND NO CODES IN PCM OR TCM. DROVE AND FOUND ENGAGEMENT FROM STOP VERY SLIGHTLY DELAYED COMPARED TO NEWER VEHICLE. RELEARNED CLUTCH CONTACT POINTS. DROVE AGAIN AND FEELS BETTER. OK AT THIS TIME.) THEN ON MAY 6 2015 14005 MILES,MY FIAT 500L DID IT AGAIN. WE WERE AT POPEYES DRIVE-THRU WAITING IN LINE TO BUY CHICKEN AND IT HAPPEN AGAIN WITH THE BURNING SMELL AND WHITE SMOKE,BUT THIS TIME MY FIAT WOULDN'T MOVE WHILE WE WERE IN DRIVE. SO I SHIFTED OUT OF DRIVE TO REVERSE FROM REVERSE TO NEUTRAL AND CAR WOULDN'T MOVE. THEN I PUT IT IN PARK AND KILL THE CAR, REATRTED CAR AND IT DECIDED TO MOVE THEN. SO IT SCARED ME AGAIN WITH THE BREATHING OF THE BURNING SMELL, IN WHICH HURTS YOUR LUNGS AND BURNS YOUR EYES. SO I BROUGHT THE FIAT TO A DIFFERENT FIAT DEALERSHIP, WITH MY CONCERN. THEY KEPT THE CAR FOR 1 DAY AND SAID. (TEST DRIVE VEHICLE AND IS OPERATING AS DESIGNED. SHIFTS THROUGH GEARS PRO PERTLY, UP SHIFTS AND DOWN SHIFTS. UNABLE TO DUPLICATE CONCERN AT THIS TIME.

WE PURCHASED THE 500L FIAT IN DECEMBER OF 2014. ON FEBRUARY 14, 2015 WE BROUGHT THE VEHICLE IN BECAUSE ON A RETURN TRIP FROM TIJUANA MEXICO WHILE IN BORDER TRAFFIC THE ENGINE STARTED SMOKING. THE CAR LOOKED LIKE IT WAS GOING TO CATCH ON FIRE, IT SMELLED OF BURNT RUBBER. WE BROUGHT THE CAR IN AND THEY EXPLAINED THAT THIS HAS BEEN HAPPENING A LOT AND THE MANUFACTURER IS AWARE BUT IS NOT DOING ANYTHING ABOUT IT. WE CONTACTED CHRYSLER USA AND OPENED A CASE, HOWEVER DURING THE CASE REVIEW THE CAR DID THE SAME THING AND WE RETURNED THE CAR TO THE SERVICE SHOP ON MARCH 10TH...WHICH AGAIN THEY SAID IT IS OUR FAULT THE CAR IS DOING THIS DUE TO DRIVER ERROR. I SHOULD EXPLAIN THAT WHAT THEY ARE CALLING DRIVER ERROR, IT IS AN AUTOMATIC VEHICLE AND CHRYSLER USA IS SAYING THAT FOR THIS VEHICLE (MIND YOU IT IS AN AUTOMATIC) IF YOU ARE IN TRAFFIC FOR A PERIOD OF 5 MINUTES OR LONGER YOU MUST SHIFT THE CAR ON EVERY OCCASION INTO NEUTRAL OR ELSE IT COULD BURN OUT THE TRANSMISSION. THEY GO ON TO SAY THAT IF THE CAR DOES SMOKE JUST PULL OVER AND AFTER THE TRANSMISSION COOLS DOWN IT IS SAFE TO DRIVE AGAIN. I ASKED CHRYSLER USA TO SHOW ME ON EXACTLY WHAT PAGE DOES IT SAY THAT IN THEIR MANUAL, FURTHERMORE THAT WHEN PURCHASING THIS CAR THE DEALER DID NOT DISCLOSE SPECIAL DRIVING INSTRUCTION FOR THEIR AUTOMATIC VEHICLE. IF THE DEALER DID DISCLOSE THAT INFORMATION BEFORE THE SALE WE WOULD HAVE NOT BOUGHT A CAR THAT COULD LEAVE US STRANDED IN MEXICO OR OTHER AREAS. AT THIS POINT AFTER CHRYSLER USA, HAS REFUSED TO SHOW US WHERE IT STATES THAT IN THE MANUAL IF IN TRAFFIC MORE THAN FIVE MINUTES THE CAR MUST BE SHIFTED INTO NEUTRAL TO AVOID BURNING OUT THE TRANSMISSION, AND THEY ARE NOT INTENDING ON DOING ANYTHING BESIDES TELL US THAT "SORRY THE CAR IS PERFORMING AS DESIGNED". WE ARE TAKING EVERY MEANS NECESSARY TO GET A BUYBACK ON THIS VEHICLE. *TR

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.
