I WAS DRIVING IN MY TRUCK WITH MY FRIEND ON SR 101. APPROXIMATE SPEED WAS 60 MPH. WE WENT AROUND A BEND IN THE ROAD OVER A CONCRETE BRIDGE EXPANSION JOINT WHERE THE PAVEMENT CHANGED LEVELS. THE TRUCK JUMPED AND BEGAN VIOLENTLY VIBRATING AND FORCED ME INTO PASSENGER SIDE GUARD RAIL OF THE BRIDGE. THE VIBRATING CONTINUED UNTIL I SLOWED DOWN TO APPROX 10 MPH. THE PROBLEM I THOUGHT WAS FIXED WITH NEW STEERING STABILIZER AND SHOCKS, A.K.A. THE DEATH WOBBLE HAS RETURNED. AFTER RESEARCH ON THE INTERNET, I CALLED MY LOCAL DODGE DEALERSHIP WITH SKEPTICISM. HE KNEW OF NO RECALLS AND IT WOULD NOT BE COVERED UNDER WARRANTY. I DO NOT FEEL SAFE IN THE VEHICLE AND DO NOT WANT MY FAMILY RIDING IN THE TRUCK. I HAVE ESCAPED INJURY TO THIS POINT.

THE OWNER CALLED HIS DISTRICT MANAGER WHO STATED HE HAS NEVER HEARD OF THIS PROBLEM (BUT THE OWNER SAID HE HAS). THE OWNER SUGGESTED I BEGIN VIDEO TAPING WHILE DRIVING. I HAVE BEEN VIDEO TAPING EACH TIME I ENTER THE INTERSTATE SO I CAN "CATCH" THE DEATH WOBBLE ON VIDEO. AT THIS POINT, I DO NOT FEEL SAFE IN THE VEHICLE AND DO NOT WANT MY FAMILY RIDING IN THE TRUCK. I HAVE ESCAPED ACCIDENT TO THIS POINT BECAUSE THERE WEREN'T ANY VEHICLES AROUND ME AT THE TIME THE DEATH WOBBLE OCCURRED. THIS IS MY 3RD POSTING. PLEASE HELP. WHAT SHOULD I DO? *TR

I WAS DRIVING WITH MY SON IN THE VEHICLE GETTING ON I-65 GOING SB. I CROSSED OVER AN EXPANSION AND THE TRUCK STARTING VIOLENTLY JUMPING AND VIBRATING. IT THREW ME FAR ENOUGH THAT I WAS ALMOST IN THE GRASS. ONCE I APPLIED THE BRAKES, THE TRUCK SLID COMPLETELY INTO THE GRASS. THE VIBRATING CONTINUED UNTIL I WAS ALMOST COMPLETELY STOPPED (APPROX 10 MPH). I NEW IMMEDIATELY SOMETHING WAS WRONG WITH THIS PARTICULAR TRUCK. I TOOK THE TRUCK TO MY LOCAL DODGE DEALER AND EXPLAINED WHAT HAD HAPPENED. THE INVOICE READS "CUSTOMER THE FRONT END WOBBLES BAD FROM 65 MPH DOWN TO 10 MPH, AFTER HITTING A BUMP". "REPLACED FRONT BRAKE CALIPERS AND HOSES. ADD FLUID". I DID NOT BELIEVE THIS WAS THE PROBLEM SO I BEGAN RESEARCHING TO SEE IF ANYONE HAD EXPERIENCED THE SAME ISSUE. TURNS OUT MANY OTHER DODGE TRUCKS HAVE EXPERIENCED THIS ISSUE. SO MUCH SO THAT IT HAS BEEN GIVEN THE NAME "THE DEATH WOBBLE". IN MY RESEARCH I HAVE FOUND NUMEROUS FIXES FOR THIS PROBLEM BUT THEY ARE ALL AFTER MARKET PARTS. I CONTINUED TO DRIVE MY TRUCK HOPING THE PROBLEM WAS RESOLVED. I HAVE DRIVEN THE SAME ROUTE MANY TIMES WITHOUT ISSUE AND I ASSUMED THE PROBLEM WAS RESOLVED. *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! THE STEERING SHAKES SO BAD THAT YOU CAN BARELY HANG ONTO IT AND I THINK ALL THE TIRES QUIT TURNING BECAUSE YOU LITERALLY ARE BOUNCING DOWN THE HIGHWAY. *TR

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.
