I HAVE A 1500 DODGE 4X4. WHILE DRIVING HOME (WITH MY THREE KIDS) I PULLED UP TO A STOP SIGN AND NOTICED WHAT FELT LIKE MY BRAKES GRINDING. I ROLLED DOWN MY WINDOW AND IT WAS VERY LOAD. I DROVE ANOTHER 2 MILES MAYBE, PULLED UP TO ANOTHER STOP SIGN ONLY TO HAVE MY DRIVE SHAFT HIT THE PAVEMENT. A FEW MEN SELLING VEGETABLES ON THE CORNER HELPED PUSH IT BACKWARDS OFF THE ROAD. MY HUSBAND LATER WENT TO PICK IT UP WITH ONE OF HIS TRAILERS AND NOTICED THAT IN 4X4 WITH THE DRIVE SHAFT REMOVED IT WAS STILL LOCKED. THE DEALERSHIP HAS HAD IT FOR THREE WEEKS AND FIRST HAD PROBLEMS WITH THE PARTS, THEN SAID THAT THE PARTS WERE ON BACK ORDER, THEN SAID THAT THE HOUSING WAS DELIVERED BUT THE GEARS HAD TO BE INVESTIGATED AND RELEASED BY A REGIONAL MANAGER IN ORDER TO BE ORDERED. WHAT WOULD HAVE HAPPENED IF THAT HAD HAPPENED DOING 75MPH DOWN THE INTERSTATE THAT I WAS HEADING TOWARDS??? I HAVE LOOKED THROUGH FORUMS AND ONLINE AND NOTICED THAT THIS IS NOT TOO FREQUENT BUT STILL COMMON. WHAT TO DO? THREE WEEKS WITHOUT MY VEHICLE, NO END IN SITE ORDERING THE PIECES OF THE REAR END AND STILL NO ANSWER ON IF THE FRONT END OR TRANSMISSION HAVE ISSUES. *TR

STARTED TO HEAR A STRANGE NOISE WHEN I WOULD LET OFF THE ACCELERATOR (EMPTY TRUCK, NO TRAILER OR CARGO). I SAID TO MYSELF 'I NEED TO GET THIS TO THE SHOP TOMORROW TO SEE WHAT IS WRONG WITH IT.' THE NOISE GOT LOUDER, AND BEFORE I GOT HOME, THE NUT HOLDING ON THE DRIVE SHAFT HAD FALLEN OFF AND CAUSED THE DRIVE SHAFT TO DROP TO THE GROUND AND MY REAR END TO LOCK UP. I WAS DISABLED IN THE MIDDLE OF AN INTERSECTION AND HAD TO CALL A TOW TRUCK. AFTER GOOGLE SEARCHING THE ISSUE, I NOTICED THERE ARE MANY CASES WITH 2009 AND 2010 DODGE RAM 1500 TRUCKS WITH THIS EXACT ISSUE. THIS ISN'T A DRIVESHAFT ISSUE, BUT RATHER A PINION\REAR END ISSUE. SEEING THE NUMEROUS REPORTS OF THIS ISSUE, I THINK A RECALL IS THE LEAST THAT DODGE SHOULD DO IN RESPONSE TO THIS ISSUE. *TR

I HAVE A 2010 RAM WITH 50K MILES ON IT AND JUST GOT A WAKE UP CALL. WHILE RUNNING WITH RUSH HOUR TRAFFIC, I TOOK MY FOOT OFF THE GAS, HEARD A LOUD WHINE, THEN KABLAM!!! THE REAR OF THE TRUCK LOCKED UP AND KICKED ME DEAD SIDEWAYS, LUCKILY I HAD JUST GOTTEN INTO A GAP BETWEEN TRAFFIC. NOTHING LIKE HAVING A FULL SIZE CREW CAB TRUCK SLIDING SIDEWAYS ON AN INTERSTATE IN THE MIDDLE OF TRAFFIC. I MANAGED TO GET THE TRUCK STRAIGHTENED UP AND AS IT WAS ABOUT TO SLIDE AROUND THE OTHER WAY I HEARD THE REAR END EXPLODE AND THE REAR WHEELS FREED UP AND I GOT OFF THE SIDE OF THE ROAD. KUDOS TO THE DRIVERS BEHIND ME, CARS AND THE 2 18 WHEELERS THAT WERE ABLE TO AVOID T BONING ME AS I WENT ON THIS WONDER RIDE. I CLIMBED OUT THE PASSENGER DOOR AND CALLED MY DEALER, THEY HOOKED ME UP WITH ROADSIDE AND AN HOUR LATER!!! WITH RUSH HOUR TRAFFIC JUST MISSING MY TRUCK BY INCHES, I GOT TO MY DEALER. THEY HAVE YET TO GET IT ON THE RACK TO LOOK AT IT. I DID CRAWL UNDER IT IN THE LOT. DRIVE SHAFT FELL OFF. THE PINION APPARENTLY CAME LOOSE, I CAN SEE IT INSIDE THE DIFFERENTIAL AND ALL THE THREADS ARE PRESENT. THE DRIVE SHAFT IS BEAT ALL UP, YOU CAN SEE WHERE IT HUNG ON THE FRAME WHEN THE TRUCK WENT SIDEWAYS. THE FRONT OF THE DIF LOOKS CRACKED, THE PINION IS INSIDE THE DIF WEDGED AGAINST EVERYTHING. THE TRANS SEAMS TO BE LEAKING FLUID AS WELL, CRACKED????? THIS IS A MAJOR SAFETY ISSUE!!!! FIRST MINE IS NOT THE ONLY RAM THIS HAS HAPPENED TO. MY DEALER HAS HAD 1 OTHER IN FOR THE SAME ISSUE, AND ANOTHER FOR NO OIL IN THE REAR DIFF. ITS JUST A MATTER OF TIME BEFORE THIS SERIOUSLY HURTS OR KILLS SOMEONE. I HAVE MANY MOONS OF DRIVING EXPERIENCE UNDER MY BELT AND WAS ABLE TO KEEP THE TRUCK FROM SPLATTERING. CALL IT SKILL, LUCK, WHATEVER, BUT IT COULD'VE TURNED OUT VERY BADLY. *KB

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.
