I HAVE CONTACTED DODGE 5 TIMES TO HAVE THEM REPLACE MY TRANSMISSION AND DIFFERENTIAL AS THEY ARE NOT WORKING PROPERLY. THEY DON'T SHIFT WHEN NECESSARY, THEY DON'T ENGAGE WHEN NEEDED AND AS A RESULT I HAVE ALMOST BEEN IN 2 ACCIDENTS. THE FIRST HAPPENED A FEW WEEKS AGO WHEN AFTER THEY HAD FAILED TO DETECT ANY PROBLEMS WHILE MY TRUCK WAS IN FOR SERVICE AND MY COMPLAINT THAT THE TRANSMISSION AND DIFFERENTIAL WERE NOT WORKING PROPERLY, THE DRIVE SHAFT ACTUALLY FELL OFF THE TRUCK WHILE IT WAS IN MOTION AND THE BOLT HOLDING THE U-JOINT FOR THE DRIVE SHAFT SHOT INTO THE DIFFERENTIAL RESULTING IN THE REAR WHEELS LOCKING UP. I WAS IN THE MIDST OF TRAFFIC WHEN THIS HAPPENED AND 2 CARS SWERVED TO MISS ME. I HAD IT TOWED TO THE DEALER, AND THE REPLACED THE DRIVE SHAFT AND A COUPLE PIECES IN THE DIFFERENTIAL, BUT DIDN'T ADDRESS THE TRANSMISSION ISSUE AND NOW THE DIFFERENTIAL WASN'T WORKING PROPERLY AND MAKING NOISE. AFTER CONTACT DODGE ABOUT IT AGAIN, THEY ARE TELLING ME THAT THE DEALER SAYS THERE'S NOTHING WRONG SO THEY WONT REPLACE THE TRANSMISSION OR THE DIFFERENTIAL EVEN THOUGH THEY ARE COVERED UNDER WARRANTY. THE DEALER SPECIFICALLY TOLD ME THAT THEY KNOW SOMETHING IS WRONG, BUT THEY AREN'T SURE EXACTLY WHAT AND THE ONLY WAY TO REALLY FIX THE ISSUES WOULD BE TO REPLACE THE ENTIRE TRANSMISSION AND THE ENTIRE DIFFERENTIAL BECAUSE THEY EACH HAVE SOME MANY PARTS TO THEM. AT THIS POINT, I WOULD LIKE TO FILE AN OFFICIAL COMPLAINT AS IT SEEMS THE ONLY WAY DODGE WILL HONOR THEIR WARRANTY IS IF SOMEONE DIES. YESTERDAY I WAS MAKING A LEFT TURN AND ONCOMING TRAFFIC ALMOST HIT ME BECAUSE THE TRANSMISSION WOULDN'T ENGAGE IN GEAR FOR THE TRUCK TO MOVE FORWARD. *TR

Feb 6, 2013

Chrysler is recalling certain model year 2009-2012 Ram 1500 trucks manufactured from February 27, 2008, through June 30, 2009, and from December 1, 2009, through October 20, 2011; model year 2009-2011 Dodge Dakota trucks manufactured from February 27, 2007, through June 30, 2009, and from December 1, 2009, through September 30, 2011; model year 2009 Chrysler Aspen trucks manufactured from January 3, 2008, through December 18, 2008; and model year 2009 Dodge Durango trucks manufactured from January 3, 2008, through December 18, 2008. The rear axle pinion nut may loosen due to an undersized pinion spline that can allow relative motion between the nut and companion flange.

Consequence & remedy

Consequence: If the rear axle pinion nut loosens, the axle can lock up and cause a loss of vehicle control and/or a vehicle crash with little warning.

Remedy: On November 7, 2013 Chrysler notified owners that dealers would install a pinion nut retainer, free of charge. In July 2015, and under a consent order with NHTSA, the company agreed to offer owners three options for remedying their vehicles: perform the original remedy, offer to repurchase the vehicle at the fair market value plus 10%, or offer an additional incentive offer towards the purchase of a new Dodge, Jeep, Chrysler, or Fiat vehicle. Chrysler will notify owners of the new recall options in a letter expected to be mailed on August 31, 2015. Owners may contact Chrysler at 1-800-247-9753. Chrysler's recall campaign number is N08.

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.
