WHEN I CALLED FOR THE THIRD TIME TODAY THEY SAID I HAD TO ACCEPT THE OFFER THEY MADE ME FOR MY VEHICLE. THEN THEY WOULD SEND A LETTER TO ME TO SIGN AND THEN THEY WOULD ASSIGN AN INSPECTOR TO LOOK AT TRUCK. I ASKED WHY WAS THIS NOT TOLD TO ME LAST WEEK WHEN I CALLED. THEY REPLIED WE DIDN'T KNOW THE VALUE OF YOUR TRUCK. I SAID YES YOU DID I PRINTED IT OFF YOUR WEBSITE AND FAX IT TO YOU ON OCTOBER 13, 2015 PER YOUR REQUIREMENTS. THE WHOLE PROCESS HAS BEEN VERY POORLY HANDLED.

THE 2010 DODGE RAM 1500 HAS SUSPENSION PROBLEMS WITH THE FRONT BALL JOINTS BEING TOO SMALL. THIS LEADS TO MY TRUCK SKIPPING ON THE HIGHWAY AND ANY BUMPY ROADS AND HAS CAUSED ME MANY, MANY TIMES TO SUDDENLY LOOSE CONTROL. ON BUMPY DIRT ROADS IT CAN HAPPEN AT 35-45 MPH. ON THE HIGHWAY IT IS VERY BAD BETWEEN 55-60 MPH IF YOU HIT ANY BUMP OR EVEN IN A TIGHT CURVE. THIS TRUCK IS HIGHLY UNSTABLE. WHEN PULLING A BOAT WHERE LESS WEIGHT IS ON THE FRONT WHEELS, IT MULTIPLIES THE PROBLEM. I AM FORCED TO NEVER GO FASTER THAN 50MPH ON ANY CURVES THAT ARE REMOTELY SHARP. THE SECOND PROBLEM IS NOT A ACTIVE SAFETY PROBLEM BUT IS A HORRIBLE PROBLEM FOR EMISSION. MY TRUCK HAS THE INFAMOUS HEMI TICK. THIS IS CAUSED BY FAULTY MANIFOLD BOLTS THAT EITHER BACK OFF, RUST OFF, OR BREAK OFF LEAVING GAPS BETWEEN THE HEAD AND THE MANIFOLD. CO2 IS LEAKING OUT OF THE ENGINE PRIOR TO GOING INTO THE EXHAUST SYSTEM. THE EPA SHOULD GET INVOLVED...

THE ISSUE AT HAND IS THAT PHONES (MAINLY APPLE IPHONE'S USING ICLOUD SERVICES) ARE DISCONNECTED FROM THE RADIOS AND ARE SUBSEQUENTLY UNABLE TO RECONNECT. I HAVE REPORTED A POTENTIAL FIX TO THE ISSUE TO UCONNECT AND WAS ADVISED THAT THEY WILL NO LONGER OFFER SUPPORT FOR THE RADIO. THE RADIO IN MY MODEL YEAR VEHICLE IS ALSO AVAILABLE UP UNTIL 2013 CHRYSLER VEHICLES AND I FIND IT CONCERNING AND DISHEARTENING THAT CHRYSLER/FIAT/UCONNECT WILL NOT SUPPORT SUCH A RECENT GENERATION RADIO. THE ABILITY TO USE BLUETOOTH IS ESSENTIAL IN TODAYS SOCIETY AS MAKING AND RECEIVING PHONE CALLS AND TEXT MESSAGES HAS BECOME THE WAY OF LIFE. SHOULD DRIVERS BE UNABLE TO USE THEIR VEHICLE'S NATIVE BLUETOOTH HANDSFREE IT COULD LEAD TO POTENTIAL DANGERS AS DRIVERS WILL MORE THAN LIKELY HAVE TO MANUALLY ANSWER THEIR CALLS/TEXTS/ETC. I DO UNDERSTAND THAT OTHER BLUETOOTH OPTIONS EXISTS HOWEVER CHRYSLER/FIAT/UCONNECT FAILING TO SUPPORT THEIR RADIO WHICH WAS SOLD WITH THIS FEATURE IS UNACCEPTABLE AND POOR BUSINESS ETHICS. THE MOST RECENT SOFTWARE VERSION FOR MY VEHICLE IS RER_2.404 WHICH WAS SUPPLIED TO ME BY CHRYSLER WITH A PURCHASED MAP UPDATE FOR THE RADIO'S GPS NAVIGATION.

Dec 20, 2017

Chrysler (FCA US LLC) is recalling certain 2016-2017 Ram 3500 Cab Chassis with a Gross Vehicle Weight Rating (GVWR) of less than 10,000 lbs, 2011-2017 Ram 3500, 4500 and 5500 Cab Chassis vehicles, 2009-2017 Ram 1500 and 2010-2017 Ram 2500 and 3500 pickup trucks, all equipped with a column shifter. Pushing the brake pedal for prolonged periods when the vehicle is running and in PARK may cause the Brake Transmission Shift Interlock (BTSI) pin to stick in the open position. With the pin in the open position, the transmission can be shifted out of PARK into any gear without pushing the brake pedal or having the key in the ignition.

Consequence & remedy

Consequence: Being able to shift the transmission without pushing the brake pedal and/or without a key in the ignition can increase the risk of an unintended vehicle rollaway that may result in personal injury or a crash.

Remedy: Chrysler will notify owners, and dealers will update the vehicle software, inspect the BTSI, and, as necessary, replace it, free of charge. The recall began February 26, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is T79.

13V038000 · Power Train:driveline:differential Unit

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.
