Coming down a ridge with a loaded hay trailer approximately 14500 pounds, the Service Electronic Braking System and Service Automatic Braking System messages appeared in the cluster EVIC display and the service brake and traction control warning lamps illuminated and there was associated chime. I applied the brake pedal and it went to the floor with zero affect. The trailer brakes didn't respond either. I used the exhaust brake and skillful downshifting (it has a manual transmission) to slow the vehicle and then used the foot applied emergency brake pedal to bring the truck to a stop. I was lucky I was already carefully descending off of the ridge and I was able to downshift and slow before engine RPM became an issue. I cycled the ignition and the warnings went away. I very carefully and very slowly completed my descent off the ridge. Now the warnings, light, and chime are incessantly coming in and then just as soon turning off. I don't trust the truck is fit for my purposes at this point in time. I hadn't been that scared since my dad and I lost a rear axle and brakes on our 1969 Ford F-250 with a load of wood in the back coming down a mountain road when I was 12.
I have a 2018 Ram 2500. Service anti-lock brakes message is intermittently coming on and off. This occurs every few seconds while driving the truck.

I have a 2018 Ram 2500. Service anti-lock brakes message is intermittently coming on and off. This occurs every few seconds while driving the truck. I took the truck to a repair facility and was displaying a code for the ABS/hydraulic control unit. I learned that there is not a known replacement to solve the issue. I have connected with other Ram owners who are dealing with the same issue while replacing unit multiple times. Ram needs to address this issue, I and along with many others are driving with no anti-lock brakes.
I’m receiving two codes; Service Antilock Brake System and Service Electronic Braking System. I met with my mechanic this morning and he said that this is a very common problem with the 2018 Ram 2500. Since this is a reoccurring safety issue i feel that Dodge should resolve not the owner.

I’m receiving two codes; Service Antilock Brake System and Service Electronic Braking System. I met with my mechanic this morning and he said that this is a very common problem with the 2018 Ram 2500. Since this is a reoccurring safety issue i feel that Dodge should resolve not the owner. Should I get in an accident from a break failure who is responsible?

Antilock braking and traction control system failed. I was driving on a snow/ice covered road and hit the brakes with no anti lock control and truck slid in road side ditch. Truck has not been repaired. This is a known problem that Dodge is well aware of. This could have caused serious injury or death under alternate driving situation or heavy traffic. Any help would be greatly appreciated.
ABS and Traction control has been lost and have created a safety risk especially during inclement weather. The ABS pump or the ABS control Module is faulty in multiple years Ram vehicles. I believe based on forums there is a recall issue with these parts.
ABS and Traction control lights keep going on and off, this still continues and it looks like Ram knows this is a safety issue. Dealers have no parts for repairs
On October 6th, 2023, my ABS and traction control light began to intermittently come on and turn off. Truck had about 60k miles on it at this time. Problem still persists now at 63k miles and seems to be getting worse. In 5 minutes of driving at freeway speeds, the lights come on and turn off about 20-30 times. I worry that my A…

On October 6th, 2023, my ABS and traction control light began to intermittently come on and turn off. Truck had about 60k miles on it at this time. Problem still persists now at 63k miles and seems to be getting worse. In 5 minutes of driving at freeway speeds, the lights come on and turn off about 20-30 times. I worry that my ABS system is not functioning properly and may result in an accident. Issue has been replicated by technicians at 4 Wheel Parts. Code reader is showing a C0020-01 code is stored in the computer.
I spent close to $1,700 to replace hydraulic control unit (HCU) at a local dealership on 4/7/2022 when my pickup truck was only 25,392 miles. Since the flashing of ABS/Traction Control lights did not stay on, I paid for the first diagnostics at this dealership but did not read the error code. I had to return couple times, and th…

I spent close to $1,700 to replace hydraulic control unit (HCU) at a local dealership on 4/7/2022 when my pickup truck was only 25,392 miles. Since the flashing of ABS/Traction Control lights did not stay on, I paid for the first diagnostics at this dealership but did not read the error code. I had to return couple times, and the service tech finally saw in person when the lights were flashing and was able to use the factory diagnostic scanner to read the error code, C0020-01. This error code directed the tech to replace hydraulic control unit (HCU). "...The replacement procedures says to drive vehicle if code comes back replaced abs module..." From online search, I found out that the replaced HCU in my truck was still XXXXXXXXAA, not XXXXXXXXAB, as shown on the invoice. Therefore, it explained that my truck now has the same ABS/Traction Control light flashing problem while driving or idling only after no more than 13,000 miles after the repair. So no cruise control could be used. I returned to the same dealership today, 1/15/2024. However, the service advisor warned me that I'd have to pay for the diagnostics ($296) that might not guarantee to find the error code since the flashing was not happening in front of the service advisor. I was told that until the flashing became permanent then return like last time. Based on this conversation, I felt that the dealership did not want to take any responsibility. My last paid repair at this dealership would only cover new part and labor for 24-months by the manufacturer, MOPAR, which is about to expire on 4/6/2024. I strongly recommend NHTSA to: 1) require MOPAR or the dealership to have free diagnostics, especially when customer provided video evidences the day before arriving at the dealership for help. 2) recall all ABS & HCU modules in 2018 Ram 2500 Diesel or gas. 3) require MOPAR to reimburse prior repairs nationally for all Ram owners experiencing the same problems prior to Nov 2022. Thank you very much

PE22012 · Loss Of Brake Performance
Opened Nov 28, 2022 · Closed Mar 3, 2025
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module ; Service Brakes, Hydraulic:power Assist:electric:control Module; Service Brakes, Hydraulic:power Assist:electric:control Module:software; Service Brakes, Hydraulic:power Assist:hydraulic
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.

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.

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
