FRONT LEFT TIE ROD WAS A SAFETY RECALL IN MARCH. I HAD IT LOOKED AT AND THE DEALER SAID IT WAS FINE. ON FRIDAY AUGUST 24TH I WAS TURNING AROUND IN A DRIVEWAY AFTER I GOT OFF THE HIGHWAY 10 MINUTES PRIOR WHEN THE TIE ROD BROKE. I CALLED ROADSIDE ASSISTANCE IN WHICH THEY TOWED TO THE NEAREST DEALER SINCE WE WERE 58 MILES FROM HOME. THE DEALER GAVE ME A RENTAL CAR AND TOLD ME NOT TO WORRY ABOUT ANYTHING, CHRYSLER WOULD HANDLE IT. ON SATURDAY THE 25TH, THE DEALERSHIP CALLED ME AND TOLD ME THAT I WOULD HAVE TO USE MY EXTENDED WARRANTY BECAUSE CHRYSLER SAID THEY WOULD NOT PAY FOR THIS, EVEN THOUGH THIS WAS A RECALLED PART. I WOULD HAVE TO PAY THE 100.00 DEDUCTIBLE. I THEN FILED A COMPLAINT WITH CHRYSLER, WHO THEN CALLED ME ON MONDAY THE 27TH AND TOLD ME THEY WOULD PAY THE DEDUCTIBLE AND I WOULD HAVE TO ISSUE THE CHECK FIRST AND THEY WOULD SEND ME THE CHECK. I DID NOT HAVE 100.00 AND TOLD THEM THAT THEY WOULD NEED TO PAY UPFRONT. THEY SAID THEY WOULD TALK TO THE DEALER AND TAKE CARE OF IT. ON TUESDAY, THE 28TH I GO TO PICK UP MY TRUCK AND THEY SAID CHRYSLER DID NOT PAY AND I HAD TO BORROW 100 TO TAKE CARE OF THE DEDUCTIBLE AND ALSO HAD TO FILL UP THE RENTAL CAR. I FEEL THAT THIS WAS ALL ON CHRYSLER AND I HAVE BEEN A DODGE OWNER SINCE EARLY 90'S AND I REFUSE TO BUY DODGE EVER AGAIN BECAUSE OF THEIR LACK OF CUSTOMER SERVICE. I COULD OF BEEN KILLED IF THIS WAS TO HAPPEN ON THE HIGHWAY AND CHRYSLER JUST DOES NOT CARE. *TR

I WAS ON THE HIGHWAY DOING AROUND 75 AND HIT A SMALL BUMP AND ALL 4 TIRES LOCKED UP, THE STEERING WHEEL AND COLUMN SHOOK VIOLENTLY, THE DASHBOARD AND EVERYTHING SHOOK REALLY HARD. I STARTED TO HIT THE BRAKES AND DID NOT LET GO OF THE STEERING WHEEL EVEN IF IT WAS SHAKING HARD. MY TRUCK STARTED TO GO ONTO THE SHOULDER THEN WENT INTO THE GRASS ON THE RIGHT AND CAME TO A STOP. IT WAS STILL RUNNING AND I GOT OUT TO LOOK AT THE TIRES AND UNDERNEATH BUT NOTHING WAS WRONG. I TOOK IT TO A DIFFERENT DEALER AND TOLD THEM I EXPERIENCED THIS BEFORE AND NOT TO TRY TO DUPLICATE THE COMPLAINT BECAUSE IT WILL GO OUT OF CONTROL. TODAY THEY CALLED ME TO SAY THEY REPLACED THE BALL JOINT (UNDER WARRANTY) BUT I HAVE TO PAY FOR AN ALIGNMENT. I TOLD THEM THAT I LOOKED THE SYMPTOMS UP ON THE INTERNET AND SAW THIS IS A REAL PROBLEM THAT CANT BE FIXED AND I DON'T WANT THIS TO HAPPEN TO ME AGAIN, THEY CAN KEEP IT. WHY DO I HAVE TO PAY 700.00/MONTH PAYMENTS AND ALSO PAY WITH MY LIFE OR SOMEONE ELSE'S LIFE TOO? I WILL NOT PICK THIS 'FIXED' TRUCK UP FROM THE DEALER. ON THE INTERNET AND YOU-TUBE ITS CALLED, THE DEATH WOBBLE AND IS WHAT HAPPENED TO ME, ONLY WORSE AND TWICE! SO, TODAY I WENT TO NHTSA AND FILED BOTH COMPLAINTS. BELIEVE ME, I MAY NOT HAVE IT ON VIDEO BUT ITS VERY VIOLENT AND YOU CANT STEER!

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.
