THIS TRUCK HAS HAD ISSUES WITH STEERING SINCE ABOUT 10,000 MILES. I HAVE HAD THE PREVIOUS STEERING RELATED RECALL (13V529000) FIXED YET THE STEERING STILL DOESN'T FEEL RIGHT. I HAD BROUGHT TO THE DEALER MULTIPLE TIMES TO ADDRESS THE ISSUE AND EACH TIME I WAS TOLD THAT NOTHING WAS WRONG. LAST SUNDAY I TURNED ON TO A TWO LANE ROAD AND AT A CRUISING SPEED OF ABOUT 35 MPH MY STABILITY CONTROL STARTED GOING CRAZY. WITHIN A FEW SECONDS, A LOUD POP. I WAS TRYING TO FIGURE OUT WHAT WAS GOING ON WHEN I REALIZED THE CAR WAS NOT REACTING TO MY TURNING OF THE STEERING WHEEL. I WAS ON A SLIGHT RIGHT CURVE AND VEERING INTO THE ONCOMING TRAFFIC LANE WITHOUT STEERING AND I SLAMMED ON THE BRAKES JUST BEFORE HITTING A PARKED VEHICLE ON THE OPPOSITE SIDE OF THE ROAD. I AVOIDED A HEAD-ON COLLISION ONLY BY CHANCE THAT THERE WASN'T A VEHICLE COMING THE OTHER DIRECTION. WITH THE KNOWN STEERING ISSUES OF THE TRUCK I AM NERVOUS THE EXISTING RECALL DIDN'T PROPERLY FIX THE TRUCK'S STEERING PROBLEMS. I HAD THE TRUCK TOWED TO THE DEALER AND I WAS TOLD THE PROBLEM WAS NOT RELATED TO THE STEERING RECALLS. I HAD A BROKEN DRAG LINK TERMINAL AND PITTMAN ARM (NEITHER UNDER WARRANTY). MY TRUCK HAS 70,000 MILES AND HAS BEEN DRIVEN ON-ROAD ONLY AND UNDER NORMAL TO LIGHT CONDITIONS FOR ALL THE MILES. IN MY OPINION THESE CRITICAL COMPONENTS SHOULD NEVER BREAK ESPECIALLY AT ONLY 70K MILES ON A SUPPOSEDLY HEAVY DUTY TRUCK. WITH MY FAMILY IN THE CAR, THIS EVENT COULD HAVE ENDED MUCH MUCH WORSE. WE ARE THANKFUL.

MY VEHICLE IS PART OF THE RAM TRUCK REPURCHASE UNDER RECALL N49. FCA US SENT ME AN OFFER FOR MY TRUCK THAT I RECEIVED OCTOBER 26. I FILLED OUT THE PAPERWORK AND E-MAILED IT TO THE LISTED ADDRESS. I CALLED THE NEXT DAY, OCTOBER 27 AND FCA US VERIFIED THEY HAD RECIEVED MY DOCUMENTATION. THEY SAID A CHECK FOR THE REPURCHASE HAD BEEN REQUESTED. I WAS INFORMED THIS WOULD ONLY TAKE 2-3 DAYS TO ISSUE A CHECK. I CALLED BACK ON NOVEMBER 17 BECAUSE I HAVE NOT HEARD FROM FCA US FOR THREE WEEKS. AT THIS POINT FCA US CLAIMED THEY WERE WAITING ON MY DOCUMENTS. I TOLD THEM THEY HAD ALREADY VERIFIED RECEIPT OF SAID DOCUMENTATION ON OCTOBER 27. THE REPRESENTATIVE SAID " LET ME LOOK" AND AFTER LOOKING VERIFIED FCA US DID HAVE THE DOCUMENTATION AND STATED THEY WOULD REQUEST A CHECK FOR THE REPURCHASE. I ASKED HOW LONG UNTIL I COULD EXPECT TO HERE FROM THEM AND I WAS INFORMED THAT THEY ARE NOT GIVING TIMES. I QUESTIONED THE FACT THAT THEY TOLD ME 2-3 DAYS 3 WEEKS AGO AND WAS TOLD "THAT'S NOT TRUE, WE ARE NOT GIVING TIMES". IS FCA US GOING TO BE HELD ACCOUNTABLE? IT DOESN'T SEEM LIKE THEY HAVE ANY INTENT IN PAYING ME OR MY FAMILY FOR OUR UNSAFE VEHICLE. THIS RAM 2500 IS MY PRIMARY VEHICLE AND I CANNOT REPLACE IT UNTIL FCA US PAYS US WHAT IS OWED AND THIS BEING OUR PRIMARY VEHICLE WE HAVE NO CHOICE BUT CONTINUE TO DRIVE THIS UNSAFE VEHICLE WITH FAULTY STEERING THAT COULD BREAK AND CAUSE US TO CRASH.

I TOLD THE DEALERSHIP ABOUT IT THEY COULD FIND NOTHING BUT AXLE SEALS LEAKING BUT DID,NT HAVE TIME TO FIX THEM. I WORK IN THE NORTH DAKOTA OIL FIELDS I HAVE TO HAVE THIS VEHICLE SO I GOT AN APPOINTMENT AT ANOTHER DEALERSHIP 100 MILES AWAY THEY COULD FIND NOTHING WRONG INCLUDING THE AXLE SEALS AND CHARGED ME 96.30. I TOOK THIS VEHICLE 1150 MILES TO NORTH DAKOTA WITHOUT ANY PROBLEMS HOWEVER ON THE WAY BACK WAS ANOTHER STORY. MONTANA RAISED THEIR SPEED LIMIT TO 80 MPH AT SLIGHTLY OVER THAT THE VEHICLE STARTED WOBBLING OUT OF CONTROL WHEN I WENT ACROSS ONE OF THOSE LITTLE BUMPS ON A BRIDGE I DID NOT THINK I WAS GOING TO GET IT UNDER CONTROL BEFOR I WENT OFF THE ROAD OR IN TO THE GUARD RAIL IT DID THIS TO ME THREE MORE TIMES BEFOR I GOT HOW. I STOPPED BY THE DEALERSHIP THAT I BOUGHT IT FROM AND THEY SAID THERE WAS NO RECALL ON THIS VEHICLE. I CALLED DODGE CUSTOMER SERVICE THEY INFORMED ME THAT IT WAS PROBABLY A WOREN TIRE OR IT WAS OUT OF ALIGNMENT. I FIND OUT THERE IS A CLASS ACTION LAWSUIT AGAINST DODGE FOR THIS AND THEY RISK MY LIFE AND MY FAMILIES LIFE NOT TO MENTION THE PEOPLE I COULD HAVE KILLED IF I HAD BEEN PASSING A TRUCK OR ANYONE ELSE ON THIS FREEWAY AT THE TIME THIS HAPPENED AT 80 MPH SOMEONE USUALLY DIES IN AN ACCIDENT. I WAS NEVER NOTIFIED OF ANY KIND OF SAFETY HAZARD WITH THIS PICKUP.

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.
