HAVE A SHAKE IN THE TRUCK! HAVE TAKEN IT IN MANY TIME TO BE FIXED! FOR FOUR YEARS HAVE HEARD IT NORMAL TO YOU WILL HAVE TO LIVE WITH IT. FINALLY AFTER 6 OR 7 DEALER ONE DECIDED IT WOULD OPEN IT UP. THE HOOKED IT UP TO THIS MACHINE THAT WOULD TELL THEM WERE IT'S COMING FROM. THEY TELL ME THE ONLY THING THEY CAN FIND IS A TRANS MOUNT. SO AFTER THAT THEY OPEN THE REAR END THEY HAD TO REBUILD IT. THEN THEY HAD TO PUT ALL NEW FROM REAR END UP TO THE ENGINE WHILE POWER TRAIN. IT STILL HAD A SHAKE! THEN THEY GOT AN OK TO OPEN THE ENGINE FROM CHRYSLER. SO THEY ADJUSTED THE VALUE LASH. O ALMOST FORGOT THE DEALER HAD MY TRUCK 7 MONTHS TO FIX THE PROBLEM. SO WHEN I PICKED IT UP FROM SZOTT M-59 ON THURSDAY AT AROUND 7 PM AND BUY SATURDAY MORNING TRUCK IS ON FIRE IN DRIVE WAY AT ABOUT 9 AM. I DROVE IT ON FRIDAY ,I PARKED IT BY 4 PM . SO IT WAS OFF FOR ABOUT 17 HOURS OR SO. HAVE NO IDEA WHY THERE WAS A FIRE. REALLY WOULD LIKE TO NO WHAT HAPPEN. HEARING THAT THERE IS A PROBLEM WITH ALTERNATOR. BUT WITH THE DEALER TAKING OF THE TOP OF THE MOTOR OFF TO READJUST THE VALVE LASH.I THINK THEY HAD TO TAKE OF THE WIRE HARNESS AND BATTERY CABLES TO WORK IN IT. WOULD LOVE TO FIND OUT WHAT WENT WRONG!!!!!!!!!! THE TRUCK WAS IN DRIVEWAY FACING SOUTH WIND WAS COMING FROM THE SOUTH. TEMP OUT SIDE WARM. TRUCK WAS SHUT OFF AROUND 4PM FRI. FIRE LOOKED LIKE IT STARTED ON DRIVER SIDE. LOOKED LIKE BATTERY AREA IS WERE THE FIRE STARTED DRIVER SIDE. I HAVE TO MUCH PAPER WORK TO SEND!!!!

PRIOR TO EPA EMISSIONS RECALL I WOULD ACHIEVE DIESEL FUEL EFFICIENCIES AS HIGH AS 21 MPG HIGHWAY, PULLING A 18 FOOT TRAILER AT A 1 HOUR DURATION. THE CITY MPG AVERAGED TO 13-15 MPG, SINCE THE EMISSIONS RECALL UPDATE MADE ON THIS VEHICLE, MPG HAS AVERAGED BETWEEN 10-13 MPG ON HIGHWAY WITH NO LOAD/NO TRAILER AND AVERAGES BETWEEN 9-11 MPG IN CITY. THESE BENCHMARKS HAVE BEEN CONSISTENTLY COMPARED AND ROAD CONDITIONS HAVE BEEN SAME. TO ADD TO THIS ISSUE, THERE HAS BEEN A LOSS OF POWER THAT HAS CAUSED UNEXPECTED HESITATION IN A NUMBER OF INSTANCES. SEVERAL TIMES I WAS PUT IN HARMS WAY AS CROSSING CITY DIVIDED HIGHWAY, CROSSING STREETS AND/OR DIVIDING HIGHWAYS WHERE THAT MULTI-DIRECTIONAL TRAFFIC LIGHTS ARE NOT ALWAYS PRESENT. TO FURTHER EXPLAIN, REALIZING THE POWER PICKUP WAS NOT PRESENT AND TURBO DID NOT SEEM TO BE 'SPUN UP' EVEN THOUGH ACCELERATION WAS INCREASED DRAMATICALLY. NOTE, TO HELP TO POSSIBLY REMEDIATE THESE POTENTIAL ACCIDENT OCCURRENCES, I MUST POWER BRAKE AND INCREASE ENGINE RPM'S TO HELP BRING THE VEHICLE TO A POWER LEVEL TO REDUCE THE RISK OF POWER LATENCY. THIS SOMETIMES HELPS BUT NOT ALWAYS BECAUSE POWER IMPOTENCY SEEMS TO BE UNPREDICTABLE AT TIMES.

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.
