THIS OCCURRED IMMEDIATELY AFTER THE VEHICLE WAS SERVICED A HALEY AUTO GROUP (CERTIFIED DODGE DEALER) FOR A RECALL ITEM (P65/NHTSA 14V-635) AND BULLETIN ITEM (25-002-14). THE VEHICLE'S COMPUTER SYSTEM DID NOT SHOW A CODE AS TO CAUSE ON EITHER OCCASION AND THE ISSUE HAS NOT BEEN RESOLVED. THE INFORMATION WAS REPORTED TO DODGE FOR TECHNICAL ASSISTANCE AND A CASE MANAGER ASSIGNED (CASE # 27675333), TO WHICH A RESOLUTION WAS NEVER REACHED. UNFORTUNATELY, AFTER PAYING HEFTY EXPENSES FOR EXPERIMENTAL PARTS THE ISSUE WAS NOT RESOLVED AND THE TRUCK WAS SOLD TO THE DEALERSHIP. I ACCEPTED AN OFFER AT A STEEP FINANCIAL LOSS TO MYSELF BECAUSE TO THE DANGEROUS SHUT DOWNS I HAD EXPERIENCED FIRST HAND WHILE DRIVING. THIS VEHICLE IS NOW OFFERED FOR SALE BY THE DEALERSHIP AND I AM CONCERNED FOR THE UNAWARE POTENTIAL BUYER! ALSO, I AM CONCERNED FOR THE SAFETY OF OTHER MOTORISTS IF THIS VEHICLE IS BACK OUT ON THE HIGHWAY. I FEEL STRONGLY THAT THIS ISSUE NEEDS TO BE DISCLOSED WHEN SELLING THIS VEHICLE AND REPORTED AS A SAFETY CONCERN.

I WAS DRIVING DOWN MY STREET TO MY HOUSE AND RIGHT BEFORE MY HOUSE I HEARD A BIG POP, I WAS DRIVING ABOUT 10-15 MPH. I WASN'T SURE WHAT IT WAS UNTIL I NEEDED TO TURN AND I COULDN'T. I GOT OUT AND MY TIRE DRIVERS SIDE TIRE WAS JAMMED INTO THE FENDER WELL AND THE TIE-ROD WAS BROKEN. WELL ABOUT 3 MONTHS PRIOR TO THIS HAPPENING I GOT A SAFETY RECALL NOTICE IN THE MAIL FOR THAT EXACT TIE-ROD. I CALLED THE DEALERSHIP AND THEY SAID THEY DIDN'T HAVE THE PART AND WHEN THEY DID GET THE PARTS IN FOR THAT RECALL THEY WOULD CALL ME. SO, BACK TO THE TIE-ROD BREAKING. I CALLED THE DEALERSHIP DWAYNE LANE IN EVERETT,WA AND ASKED THEM IF THEY TOW VEHICLES THAT ARE AFFECTED BY RECALLS AND IF I COULD GET A LOANER/RENTAL CAR AND THEY SAID NO. THEY ALSO SAID THEY STILL DIDN'T HAVE THE PARTS TO FIX THE ISSUE(RECALL). I WASN'T HAPPY WITH DODGE DUE TO THIS ISSUE. SO ABOUT 3 DAYS LATER THE DEALERSHIP CALLS ME BACK AND SAYS THEY GOT THE OK FROM DODGE TO PUT ON THE "RECALLED TIE-ROD" SO I CAN HAVE MY TRUCK BACK UNTIL THE FIX(NEW PARTS FROM THE RECALL) IS AVAILABLE. I ASKED THE SERVICE MANAGER IF HE WOULD EXCEPT THAT IF HIS FAMILY WAS IN THE VEHICLE AND HE SAID YES. I WASN'T HAPPY WITH THAT DECISION FROM DODGE TO PUT ON THE RECALLED TIE-ROD END TO GET ME BACK ON THE ROAD. SO, I ENDED UP GETTING MY TRUCK BACK WITH FAULTY PARTS ON IT AND DROVE IT FOR ABOUT 2-3 WEEKS AND THE DEALERSHIP CALLED TO SAY THE NEW PARTS ARE IN. THEY FIXED IT AGAIN AND HERE I AM NOW. NOW WITH THIS BUY BACK FROM DODGE, THE WAY I SEE IT SINCE THE RECALL HAS BEEN FIXED I WOULDN'T HAVE THE OPTION FOR DODGE TO BUY MY TRUCK BACK. I THINK THEY SHOULD HAVE TO GIVE ME THE OPTION ESPECIALLY SINCE MINE ACTUALLY DID BREAK WHILE I WAS WAIT FOR DODGE TO GET THE RECALL PARTS. PLEASE LOOK INTO THIS I DO NOT FIND THIS EXPECTABLE BUSINESS, IT WASN'T SAFE TO PUT THE RECALLED PART BACK ON MY TRUCK AND DODGE SAID IT WAS.

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.
