2012 Dodge 1500

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.

While the vehicle was sitting in the driveway not running, the back of the headlight caught on fire. There wasn't any incedents (e.i. any collision, repairs) prior to the indecent. It is available for inspection. No dealership report yet, but have an appointment with local dealership Tuesday to get an itemized estimate for the repairs.

The contact owns a 2012 Dodge Ram 1500. The contact stated that while driving approximately 55 MPH and hauling a camper, the rear wheels locked up, and the contact lost control of the vehicle and the vehicle spun out. The camper jackknifed during the failure. The rear axle and wheels locked without warning. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 146,000

My 2012 Dodge developed an engine issue at 129,000 miles. The issue was rough idling and no acceleration. I took it to a Dodge dealer. They diagnosed it as a chronic cam issue with this generation Chrysler hemi engine. I had the cam and replaced at Waldorf Dodge. The cost was at $3400. I believe this is a known problem and Dodge is aware of exactly why it happens. Lack of oil pressure to two of the cylinders that are dropped while driving for fuel economy. This should be Dodge problem not the consumer. I take excellent care of my vehicles. I also have a 2004 Dodge truck but that’s over 450,000 miles on it same engine same transmission.

The contact's ex-wife owns a 2012 Dodge Ram 1500. The contact stated that while his ex-wife was driving at an undisclosed speed, the vehicle stalled. There was no warning light illuminated. The driver shifted into park(P) and then restarted the vehicle. The contact stated that the starter and key fob were replaced twice. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Campaign Number: 23V265000 (Power Train); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was 165,353.

The contact owns a 2012 Dodge Ram 1500. The contact stated that while driving approximately 65 MPH, the check engine warning light was flashing, and the vehicle unexpectedly decelerated. While depressing the accelerator pedal, the vehicle was shaking and continued decelerating. The vehicle was pulled over to the side of the road. A certified mechanic was contacted and advised the contact to drive the vehicle approximately 45 MPH with the hazard lights flashing to the repair shop. The mechanic diagnosed a misfire in cylinder #2, lifters failure, causing the camshaft failure, which allowed metal debris to enter the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 80,000.
