Ram 1500 Investigations
NHTSA Office of Defects Investigation records
High pressure fuel pump failure
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-generati
Vehicle Rollaway
Basis â 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 â 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
Software security vulnerability
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 201
Intermittent/Comp Loss of Power 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.
Post Recall Remedy Brake Transmission Shift Interlock (BTSI) Failure
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. To review the ODI reports cited in the Op
Engine Stall With Intermittent Restart
The Office of Defects Investigation (ODI) has received 80 consumer complaints alleging an engine stall and loss of motive power on model year (MY) 2022 RAM 1500 pickup trucks and 2022 Jeep Wagoneer SUV vehicles. The particular engines in the subject vehicles are equipped with the Fiat Chrysler Automotive Group LLC (FCA) 5.7L Hemi eTorque system. The eTorque system is a mild hybrid system that lets the vehicle partially power itself. It accomplishes this by converting the captured energy from the braking system into electricity for the battery pack, which is then used to power a variety of electrical components. ETorque engines replace the alternator with a 48-volt battery-powered belt drive and a motor generator. The motor generator provides extra torque to the crankshaft during gear changes. Simultaneously, the motor generator uses the 48-volt battery pack to increase torque. Many of the complaints state that the vehicle's engine would shut off, often while travelling at slow speed, the vehicle would shift into park and apply the emergency brake. The vehicles were sometimes able to be restarted. In addition, complaints state that the malfunction warning light with the battery faul
About NHTSA Investigations
NHTSA investigations include Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), and Audit Queries (AQ). Investigations may lead to recalls if defects are confirmed. An open investigation means NHTSA is actively examining the issue.
