NHTSA Defect Investigations for the 2015 Ram 1500

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2015 Ram 1500, both ongoing and closed, are listed below:

  1. INVESTIGATION: Software security vulnerability

    NHTSA Defect Investigation #RQ15004

    Component(s): Electrical System: Software

    Summary: On July 23, 2015, Fiat Chrysler Automobiles (FCA) launched Safety Recall 15V-461 to remedy security vulnerabilities in approximately 1.4 million model year (MY) 2013 through 2015 vehicles equipped with Uconnect head units (HU) 8.4A (RA3 radio) and 8.4AN (RA4 radio) manufactured by Harman International.On July 24, 2015, the Office of Defects Investigation (ODI) opened Recall Query, RQ 15-004, to investigate HU security vulnerabilities and remedy effectiveness in the recalled population and to determine whether similar units have been supplied for use in other FCA vehicles.In an August 11, 2015 letter, FCA submitted a second Part 573 safety recall report expanding the scope of the Uconnect RA4 model radio to include additional 7,810 MY 2015 Jeep Renegade vehicles manufactured from September 18, 2014 through June 25, 2015 (Recall 15V-508).Scope analysis indicated that Uconnect radios installed in FCA vehicles not included in recalls 15V-461 or 15V-508 (subject recalls) are not equipped with built-in cellular access or short range wireless communication features and, thus, do not contain the security vulnerabilities addressed by the subject recalls. SUBJECT VEHICLES: MY2014 through 2015 Dodge Durango, Jeep Grand Cherokee and Jeep Cherokee sport utility vehicles; MY2013 through 2015 Ram 1500, 2500, 3500 and 4500/5500 pickup trucks; MY2013 through 2015 Dodge Viper vehicles; and MY2015 Chrysler 200, 300, Jeep Renegade, Dodge Charger and Challenger vehicles.According to FCA, long and short range wireless vulnerabilities identified in the recalled vehicles could allow unauthorized third-party access to, and manipulation of, networked vehicle control systems.Successful exploitation of the vulnerabilities, coupled with reverse engineering of networked microprocessor control modules, could result in unauthorized manipulation of vehicle control systems. This unauthorized manipulation of vehicle controls and systems could expose the driver, vehicle occupants or other highway users to an increased risk of injury.FCA and its network provider, Sprint, conducted a nationwide campaign to block access to a radio communications port that was unintentionally left open.On July 27, 2015, short range wireless vulnerabilities were also blocked.Finally, third party security evaluation and regression testing identified vulnerabilities that were either remedied by Sprint or through updates to the FCA Uconnect software.ODI identified a total of 30 complaints or field reports on unique vehicles submitted by FCA (29) or received by NHTSA (1) alleging incidents of theft from a vehicle or anomalous performance that the owner alleged were caused by, or may have been caused by, remote hacking.Twenty-six (87%) of these reports were submitted after a magazine article was published on July 21, 2015, describing the remote hacking of an FCA vehicle by researchers who were able to affect the operation of various vehicle control systems, including the service brakes, steering, throttle and ignition.Most of the complaints involved vehicle systems that were not safety critical (e.g., complaints related to radio, navigation system, or air-conditioning control) and did not affect vehicle control.Three complaints reported engine stalls.One owner reported sudden unintended acceleration allegedly related to hacking.None of the complaints or field reports reviewed involved the steering and braking vehicle control effects demonstrated by the research hackers prior to the recall.There were no confirmed incidents of hacking in any of the records reviewed by ODI.The remedies completed by Sprint and FCA appear to have eliminated vulnerabilities that might allow a remote actor to impact vehicle control systems.This recall query investigation is closed; this action does not constitute a finding by NHTSA that a safety-related defect does not exist.

  2. INVESTIGATION: Vehicle Rollaway

    NHTSA Preliminary Evaluation #PE16014

    • Status:
    • Date Opened: December 16, 2016
    • Date Closed: N/A
    • Recall: No recall yet

    Component(s): Power Train:Automatic Transmission
    Power Train:Automatic Transmission:Control Module (Tcm, Pcm)
    Power Train:Automatic Transmission:Gear Position Indication (Prndl)

    Summary: The Office of Defects Investigation (ODI) has identified 43 complaints alleging vehicle roll-away from a parked position in model year (MY) 2013-2016 Ram 1500 and MY 2014-2016 Dodge Durango. These subject vehicles are equipped with an electronically shifted transmission and electronic rotary control for driver gear selections.The reports alleged that the unintended motion occurred after the driver moved the transmission gear selector to Park and exited the vehicle.Nine injuries have been alleged in eight reports, 25 crashes are alleged. Thirty-four of the reports alleged that the vehicle was moving while the shifter indicated that it was in the park position.Many of the incidents alleged the engine was running, however it was noted as off in a few cases. Notably none of the reports indicate that the parking brake was engaged at the time of the roll-away incident.Subject vehicle owners, and in fact all drivers, should always apply the parking brake to prevent vehicle roll-away.A Preliminary Evaluation has been opened to assess the scope, frequency, and safety-related consequences of the alleged defect.The ODI complaints cited above can be viewed at www.safercar.gov under the following ODI identification numbers:10554951, 10559744, 10617268, 10648455, 10664380, 10701261, 10726180, 10744809, 10746012, 10746574, 10749304, 10761819, 10764187, 10787674, 10808836, 10820611, 10825024, 10859918, 10860998, 10861070, 10861275, 10861466, 10863765, 10865590, 10870288, 10875626, 10875918, 10883952, 10884961, 10887416, 10896337, 10898192, 10898999, 10899161, 10903709, 10906809, 10907102, 10910068, 10911170, 10914057, 10917680, 10917771, and 10926262.
