An investigation means NHTSA has decided a pattern is worth examining. A
preliminary evaluation is often closed with no action; an engineering
analysis is the stage that usually precedes a recall.

the power train
The Office of Defects Investigation (ODI) has received 14 Vehicle Owner Questionnaire (VOQ) reports and 6 EWR Death & Injury (D&I) reports describing post recall remedy failures of the brake transmission shift interlock (BTSI) system in certain Model Year (MY) 2013-2018 RAM pickup trucks.The subject vehicle models include 1500, 2500, 3500, 4500, and 5500 trucks equipped with a column mounted shift lever.The failures of the BTSI described in the VOQs occurred on vehicles that had all previously been repaired under recall 17V-821 or 18V-100.Both recalls address a potential condition which can cause the BTSI locking pin to become stuck allowing the transmission to be shifted out of Park without depressing the brake pedal and/or without having a key in the ignition.Shifting the transmission out of Park when not having the brake pedal depressed can result in a vehicle rollaway. ODI is opening this Recall Query (RQ) to review the effectiveness of the 17V-821 and 18V-100 recall remedies, understand the root cause of additional vehicle rollaway incidents, and identify any other possible root cause that may affect the performance of the BTSI system.

the steering
The Office of Defects Investigation (ODI) has received 380 reports from consumers alleging an intermittent or complete loss of power steering assistance in certain 2013-2016 Ram 1500.The failure allegations occur at various speeds with limited detectability to the driver.On March 23, 2016 Fiat Chrysler Automotive (FCA) conducted recall campaign 16V-167 to address a possible contamination of the electrical power steering unit in certain model year 2015-2016 RAM 1500. The recall involved 440 vehicles and potentially resulted in loss of power steering assist.Consumer complaints indicate a similar failure may be occurring in vehicles that are out of scope of the recall.A Recall Query has been opened to determine if the scope of the recall mentioned above is correct or if another defect might exist that causes the alleged steering concerns.The reports cited above are listed in the attached document.
High pressure fuel pump failure

Still open engineering analysis · opened March 17, 2023 · led to recall 24V957
the diesel fuel system
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337
Closed preliminary evaluation · opened December 16, 2016 · closed January 25, 2024

Basis – On December 16, 2016, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE16-014 to investigate 43 vehicle rollaway incidents with operators alleging they had shifted to Park and then exited the vehicle prior to the rollway incidents. These complaints involved multiple Fiat Chrysler Automobiles (FCA) model and model year vehicles that share a common electronic rotary shifter design. Of the 43 consumer complaints, 25 complaints alleged crashes, and eight complaints alleged at least one injury. Subject Vehicles – When NHTSA opened the investigation, the subject vehicles were model year (MY) 2013-2016 Ram 1500 vehicles and MY 2014-2016 Dodge Durango vehicles equipped with a rotary electronic shifter. However, NHTSA expanded the scope of the investigation to include subsequent model years of the same model vehicles when the Agency learned that those new model year vehicles use the same rotary shifter. Additionally, all subject vehicles manufactured by FCA are equipped with electronic rotary shifters supplied by Kostal Automotive. Reason for closing - During the course of this investigation, ODI did not find evidence that a vehicle-based design or manufacturing defect was the cause of vehicle rollaway incidents on the subject vehicles. Nevertheless, given the risk of a vehicle rollaway, FCA’s CSN actions provide automated vehicle securement when an operator attempts to exit the vehicle without successfully achieving a Park position with the rotary shifter mechanism. ODI closely monitored the subject vehicles on which the CSN actions implement a vehicle securement strategy and found that the CSN actions were effective in reducing the frequency of vehicle rollaway incidents in the subject vehicles. ODI analyzed the incidents when a CSN had been implemented and a rollaway still occurred, and ODI was unable to find an actionable defect that caused vehicle rollaway incidents. ODI found that the failure rates on subject vehicles that received a CSN remedy were similar to the failure rates on other vehicle populations and additionally had similar mechanisms as other vehicle populations such as slippery surfaces and various mechanical failures. Furthermore, as discussed above, after FCA’s release of the CSN actions, consumer complaints have decreased significantly. Given the absence of an identified safety defect based on available information and FCA’s customer satisfaction campaign which addresses the failure mode, further action is not warranted at this time. Accordingly, this Preliminary Evaluation is closed. However, the Agency reserves the right to take further action, if warranted.Please see the attached detailed closing summary for more information.

the electrical system
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 mi
