Post Recall Remedy Brake Transmission Shift Interlock (BTSI) Failure

Opened Jul 3, 2025

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.

Steering loss due to linkage separation

Opened Dec 1, 2019
Closed Nov 20, 2025

On December 17, 2018, NHTSA's Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18016 to investigate alleged drag link failures in the steering system on model year (MY) 2015 and 2016 Ram 2500 trucks manufactured by FCA US, LLC (FCA).  The drag link failures were found to be due to a safety defect with the steering linkage where the drag link adjustable connector (used to adjust the steering system), held in position by two opposing jam nuts, can loosen.   The loosening of this part can lead to wear and deterioration of the threads and eventual separation of the drag link, causing loss of steering.  During the course of PE18016, it was found that two styles of drag link were used by FCA on the subject vehicles.  The subject vehicles consist of two drivetrain types including four-wheel drive (4WD) and two-wheel drive (2WD).  The 4WD and 2WD trucks used drag links of differing design but both incorporated the same threaded connector.  In January 2019 FCA issued recall 19V-021 to address a potential loss of steering control in certain Model Year (MY) 2013-2018 4WD RAM 2500 and 3500 trucks.  The trucks using the 2WD style drag link were not included in the scope of recall 19V-021. ODI upgraded PE18016 to an Engineering Analysis EA19004 on December 12, 2019.  The purpose of EA19004 was to investigate if the root cause of the safety defect addressed by recall 19V-201 also affected the 2WD trucks and evaluate FCA’s rationale for not including them. ODI also monitored incoming consumer complaints regarding the remedy associated with 19V-021 and evaluated the suitability and long-term effectiveness of the prescribed repair. In the Defect Information Report submitted for recall 19V-021, FCA stated that the outboard jam nut could loosen and result in damage to the threading of the steering drag link connector.  This could cause a separation in the drag link resulting in a loss of steering control.  FCA determined that only the 4WD style drag link was affected and did not recall trucks with the 2WD style drag link due to design differences that made it unsusceptible to this failure mode.  The repair remedy called for the steering coupler to be tightened to the proper torque prior to the jam nut being spot welded to the coupler body. If the coupler has already become detached or correct torque cannot be obtained, the drag link is to be replaced with an updated unit that went into production on the MY2019 RAM trucks.This updated unit uses a clamp to secure the coupler in place of the jam nuts used on original style components. In order to determine if the 2WD drag link was susceptible to the same defect found on the 4WD vehicles, ODI requested that our Vehicle Research and Test Center (VRTC) conduct testing on both RAM 2500 4WD and 2WD trucks.  This testing was to determine operating conditions that might lead to loosened jam nuts of the recalled 4WD design and recreate these conditions on the 2WD vehicles to discover whether the 2WD design would also experience the loosening defect.  Results from VRTC’s dynamic testing indicated that when the jam nuts are significantly under-torqued, they may loosen further from regular vehicle operation on the 4WD vehicles.  Further, VRTC testing does not refute FCA’s assertion that the failure mechanism does not exist in the 2WD steering system. At the time of this closing resume, ODI has only received two allegations of drag link separation on 2WDvehicles.Neither could be validated as resulting from loose jam nuts. Since the release of recall 19V-021 ODI has received consumer complaints regarding the appearance of the spot weld applied to the defective drag link and the inability to have the steering properly aligned after welding of the jam nut.  In September 2023, FCA provided owners with a supplemental Vehicle Alignment Clarification notification that provided information on an updated alignment procedure. Regarding the spot weld remedy used on the 4WD vehicles, ODI is concerned about the remedy in that during an alignment by a non-dealer repair facility, the spot weld might not be replaced after the alignment.   To date there is no complaint trend of post alignment drag link separations, weld failures or other safety related incidents on remedied vehicles. This investigation is being closed with no further action. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

Steering loss due to linkage separation

Opened Dec 17, 2018
Closed Dec 12, 2019

On December 17, 2018, NHTSA's Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE) 18-016 to investigate the steering system on model year (MY) 2015 and 2016 Ram 2500 manufactured by FCA US, LLC (FCA). Four complaints were received alleging separation of the drag link, a steering linkage that connects between the right front steering knuckle and the pitman arm on the steering box output shaft. The failures were found to be at a threaded coupler within the drag link used for adjusting the length of the linkage during routine maintenance (alignment) of the steering system.Once separation occurs, turning the steering wheel has no effect, and there is no way for the driver to control or maintain the direction of the vehicle. During the investigation, it was determined that the same threaded coupler was used on two different drag link designs FCA manufactured on MY 2013-2018 Ram 2500 and 3500 pickups. FCA refers to the designs as either 4x2 or 4x4 style. In both designs, the coupler is prevented from turning on the drag link via two jam nuts that are tightened against the coupler. In its response to NHTSA's March 15, 2019, Information Request (IR) letter, FCA identified 48 incidents alleging separation of the steering linkage at the coupler resulting in a loss of steering control. Of those, 13 involved a crash, one of which resulted in an injury. All of the separations involved the 4x4 style drag link. Additionally, FCA's IR response refers to over 300 4x4 style equipped vehicles that experienced, or may have experienced loosening of one or more coupler jam nuts. On January 25, 2019, FCA submitted a Defect Information Report (DIR) initiating NHTSA Recall No. 19V-021. In its DIR, FCA stated that the outboard jam nut in certain MY 2013-2018 Ram 2500 and 3500 could loosen potentially resulting in damage to the coupler and/or drag link threading allowing one end of the drag link to separate. The DIR notes that drag link separation results in loss of steering control, which in turn can cause a crash without warning. FCA's DIR did not identify a root cause for the defect, however it posits that an improperly torqued outboard jam nut could loosen, and with long-term vehicle use, cause damage to the outer link bar and/or coupler threads due to relative motion between the two components. The scope of Recall 19V-021 included vehicles with the 4x4 style drag link only. Also discussed in its IR response, FCA noted that the 4x2 style drag link contains a design difference (the outboard portion of the drag link is straight while the 4x4 style contains a bend) which it suggests may result in differences in the mechanical (bending) loads presented at the coupler and jam nut interface. Moreover, the DIR states that While root cause of the 4x4 style defect has not been established, FCA US believes that bending loads on the drag link is, at least, a causal contributing factor. FCA notes it did not identify any reports alleging 4x2 style separation as well as only three reports of loosening of jam nuts, two of which resulted in loosening that provided obvious warning to the vehicle operator, indicating a different failure mode.NHTSA is upgrading this investigation to Engineering Analysis (EA) 19-004 in order to continue to monitor the subject 4x2 style vehicles for evidence of field failures. Additionally, in conjunction with NHTSA's Vehicle Research and Test Center, ODI intends to more thoroughly study potential root cause(s) of the 4x4 style defect mechanism, and if identified, will seek to determine if the 4x2 drag link is susceptible to the same mechanism(s). NHTSA will also evaluate the long-term suitability of the recall

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

On two separate occasions, once in 2025 and again in July 2026, while pulling a travel trailer an emissions control fault in the EGR system caused the Cummins turbo diesel engine in the truck to lose power. At this reduced power, highway speeds could not be maintained, and even small hills were difficult to climb. This is a significant safety problem, and the dealerships could not provide a timely repair due to lack of parts availability. The manufacturer of software in the engine control system does not allow the use of aftermarket parts. This is monopolistic and anti-competitive. An emissions control fault Code should not deprive me of the use of my vehicle.

Mopar has discontinued parts for many Ram vehicles with a 6.4L Hemi motor including the exhaust manifolds. My exhaust manifold is currently cracked and has an audible leak. Exhaust enters the cab of the vehicle when starting, idling, or reversing. They have no indication of providing a fix for this and the parts are not available aftermarket either. This broken piece not only affects the performance and safety but renders my truck unusable per DOT guidelines and would be red flagged during a roadside DOT check. In my area I know of three other trucks with the same issue. I have tried to reach out to the manufacturer with no response and all the dealers I have tried to reach do not have a solution. This problem can affect trucks as new as 2019 and old as 2011.

MANUFACTURER VIOLATION OF FEDERAL TREAD ACT REIMBURSEMENT REQUIREMENTS Vehicle experienced ABS hydraulic control unit failure in September 2022 with warning lights and transmission shifting problems. Repairs cost $5651 addressing brake system hydraulic control unit defects. In November 2024, manufacturer issued Recall C7B/NHTSA 24E-100 for identical hydraulic control unit ABS defects affecting 2012-2018 Ram vehicles. Federal regulation 49 CFR 573.13 requires manufacturers reimburse pre-notification repairs reasonably necessary to correct recalled defects. Manufacturer FCA US LLC improperly denied reimbursement under case 92237530, claiming parts not covered under recall repair. This violates federal TREAD Act mandatory reimbursement requirements. Manufacturer referenced wrong recall campaigns in denial letters, demonstrating failure to properly evaluate claim under applicable federal regulations. Request NHTSA enforcement action to compel manufacturer compliance with federal reimbursement obligations. Manufacturer operates established reimbursement system but improperly applies federal requirements. Safety defect was present in 2022 and subsequently recalled, establishing federal obligation for pre-recall repair reimbursement.
