Recalls and investigations

2 recalls on the fuel and propulsion cover the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.

Post recall remedy brake transmission shift interlock (btsi) failure. Open.

NHTSA summary
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.

High pressure fuel pump failure. Open, led to recall 24V-957.

NHTSA summary
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

Vehicle rollaway. Closed jan 25, 2024.

NHTSA summary
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 th

Should you keep driving it?

This page can't tell you that. 1 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
