They have made parts for a 2500 model but neglected to fix the 3500, 4500 and 5500 models. They will fix it with another faulty sensor and still expect owner to pay a 1700 repair bill even though it’s a recall. It’s ridiculous on the time this is taking.

Stellantis is unable to provide a timey remedy for NHTSA Recall Number24V-896. The hydraulic control unit ("HCU") is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss. The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning. Driving the vehicle is a safety risk to me and the public. The vehicle is garaged at an authorized dealership since 2/13/25 and has resulted in a loss of income totaling $40,000 as the truck was used for transporting heavy loads. Additionally, I have paid $9,000 towards the monthly truck note and insurance for a vehicle that I cannot drive. Stellantis has not provided an adequate solution, and they are ill-equipped to be a manufacturer of vehicles in the United States. Stellantis is actively misrepresenting safety information to the public without any regard for the public’s safety. Out of an abundance of caution, I filed Better Business Bureau complaint case #[XXX] on [XXX] with the Detroit and Eastern Michigan office after Stellantis advised me that the 2018 Ram 3500 was safe to drive even though the recall was not repaired. Stellantis’ response can be viewed by the public at the Better Business Bureau of Detroit and Eastern Michigan’s website. It reads as follows: “We issued this recall out of our commitment to your safety and recommend that you complete the repair as soon as the remedy becomes available. However, please rest assured that you can continue driving your vehicle safely in the meantime." They made 5.5 billion in profit in 2024 and they won't deal fairly regarding a rental vehicle. On 7/17 they told me they would reimburse up to $60 then 8 days later they said up to $50. When I submitted my rental receipts they said their system is down.

The stereo malfunctioned on several occasions, I have taken it to the dealer and had a new stereo put in. My safety was at risk because the radio started jumping from station to station and calling people in my contact list. All of these increased concerns and my driving was impacted. This made it impossible to drive safely due to this issue. I had to pull over each time and disconnect my Bluetooth and unplug my phone for hands free driving. This issue caused a very unsafe and distracted event. Yes this has been confirmed. It has not been inspected by the police; this is a huge issue with these trucks there are several complaints that have been turned in. There were no warnings. The radio would work fine and then start going off on a tangent, there is no way to even turn off the radio to prevent this from happening. This needs to be covered by Dodge Ram, this issue is unsafe and could cause an accident.

On May 3, 2025, while driving my 2018 RAM 2500 with approximately 46,000 miles, the check engine light came on and the engine immediately experienced a significant loss of power. The vehicle entered a limp mode condition, drastically reducing speed and acceleration. I was forced to pull into a nearby business as the truck could not maintain safe highway speeds, creating a traffic hazard and contributing to congestion. The vehicle was diagnosed by a repair facility as having a failed turbo actuator, a critical component in regulating turbo boost and engine power delivery. After researching this issue, I have found numerous similar complaints and reports from other RAM truck owners on various owner forums and websites, indicating this may be a recurring and potentially widespread defect in these vehicles. Given that this failure occurred at relatively low mileage, caused a hazardous driving condition, and seems to be a commonly reported problem, I believe this issue warrants investigation by NHTSA for potential safety risks and manufacturer accountability. No injuries or property damage occurred, but the incident posed a significant safety risk to myself and other drivers.

On March 3rd, This dealership replaced the stop sale safety recall on our Commercial vehicle (C4B) with a part that was not created for our truck. This resulted in hydraulic brake fluid spewing out of the HCU all over significant areas under the hood, including the ABS Module and wiring. Upon realizing the HCU was spewing hydraulic brake fluid, we brought the truck back on March 7th, and again, the dealership replaced the HCU with the incorrect part (but assuring us it was the actual part for this specific recall) and Sam (service advisor) told us they would also be replacing the ABS Module and the wiring associated, as the ABS module had also been recently replaced and was still covered under warranty. When we received the car back, Sam (service advisor) explained that they would like the truck back at a later date to replace the wiring - that they have already replaced the ABS module so we will still see the ABS light, but only because the wiring needs to be redone.  We picked up our truck on Friday March 8th, and when my fiancé began his route on [XXX] with his trailer attached, he made it about 20 miles before his truck completely shut down mid-drive while on a busy road- forcing him to have to coast over a 4 lane roadway and into a ditch avoiding collision of oncoming traffic with his trailer and equipment attached. We discovered that the mechanics had fraudulently replaced our HCU with another trucks HCU and had to force the recall through Mopar's reimbursement process, as it was rejected multiple times because the remedy is not currently available therefore unable to be completed. I have attached the full story in a PDF document for further information.  Phone: [XXX] Email: [XXX] contact me for any information you may need in addition to this.

There is nothing I can do to make it go away or function correctly. I took it to the dealer to talk about the recall and asked if I could go ahead and pay to have the replacement parts installed and they told me everything was unavailable. This problem has been going on for over two months. It is unsafe, now I don't have any ABS or traction control in the middle of the winter, this is the worst possible time this could happen.

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 Office of Defects Investigation (ODI) opened this investigation on November 28, 2022, after receiving 134 reports from consumers alleging an intermittent or permanent loss of braking performance in certain 2017-2018 Ram 2500-3500 pickup trucks manufactured by Fiat Chrysler Automobiles (FCA). The alleged failures continued to occur at a steady rate across both models, at all speeds, with limited detectability.  Consumers complained that the Anti-lock Braking System (ABS) warning light illuminated on their vehicles.  The ABS module works in conjunction with the Hydraulic Control Unit (HCU), an electromechanical device that controls hydraulic pressure to the individual wheel brake assemblies, to manage braking forces during emergency stops. During this investigation, ODI received over 2,500 consumer complaints concerning ABS or HCU warning lights that illuminated on the dashboards of their vehicles.  Many consumers described also having trouble with cruise control, traction control, or electronic stability control.  Of the complaints received, over 50% mentioned that the ABS or HCU warning light was intermittent in nature. ODI learned that in January 2021, FCA was aware of a problem with the ABS pump motors on the subject vehicles.  FCA had been working with the supplier, ZF, on an issue concerning swelling of the brushes inside the motor.  According to a briefing given by ZF to FCA on January 15, 2021, the ABS, electronic stability control (ESC), traction control system (TSC) and other functions utilizing the motor would be disabled in the event of a problem with an ABS pump motor.  ZF also informed FCA that Slip Control would be inhibited with the driver warning lamp illuminated, base braking would not be affected, and FMVSS stopping distance requirements would still be met. In order to better understand the potential consequences of the brushes swelling and the disablement of the ABS, ESC, TSC and other functions, ODI requested that NHTSA's Vehicle Research and Test Center (VRTC) conduct testing on a subject vehicle with a faulty pump motor installed. During the testing, VRTC found that as the brushes started to swell in the motor, the warning lamp could illuminate intermittently, causing confusion to drivers.  Although the warning light illuminated intermittently, VRTC discovered that the pump was not working properly regardless of the warning light status.  In this condition drivers might think that their vehicle is operating normally when the warning light is off, but instead, the ABS, ESC, TSC and other functions supported by the pump will not work. Following a series of meetings with FCA to demonstrate the findings ofVRTC's testing, FCA conducted an internal review and on November 27, 2024, FCA submitted safety recalls 24V-896 and 24E-100. In view of the recalls being conducted by FCA, ODI has closed this Preliminary Evaluation.  The Agency reserves the right to take additional action if warranted by future circumstances.

EA19004 · Steering Loss Due To Linkage Separation

Opened Dec 1, 2019 · Closed Nov 20, 2025

Status: closed (inferred from source dates) · Steering:linkages:drag:link:connection

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.

PE18016 · Steering Loss Due To Linkage Separation

Opened Dec 17, 2018 · Closed Dec 12, 2019

Status: closed (inferred from source dates) · Steering:linkages:drag:link:connection

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
