2017 Ram 3500 Brakes

The problem with the ABS module started in 2019 when the truck had 43000 miles. The dealership told mee what the problem was but didn't have the parts to repair it. I've been driving it since then with no anti lock brakes, traction control, and no cruise control. This seems unsafe to me and all other drivers. I have contacted the dealership and there is still no remedy for the issue. Please consider this a formal complaint. Thank you.

I have been trying to get a ram dealer to fix the hcu unit under recall. All I get is no remedy available, im driving a truck with an open “ safety recall” that’s been a recall for over a year. I never stop listening to warning buzzers and flashing alarm lights.

The contact owns a 2017 RAM 3500. The contact stated that while driving at an undisclosed speed, the service brakes activated, and the vehicle slid and crashed into a deer. The contact stated that the deer appeared instantly. The brake pedal was depressed; however the vehicle failed to stop, and the vehicle crashed into the deer. The ABS and traction control warning lights were illuminated. The contact stated that the failure occurred two times, and each time the contact's vehicle crashed into a deer. The contact stated that each time the deer appeared so fast. In addition, the contact stated that the area in which the contact resides was highly populated with deer. The vehicle was towed to an independent mechanic for damage repairs to the exterior of the vehicle. In addition, the vehicle was taken to an independent mechanic, where it was diagnosed with a failed HCU module. The contact was informed that the HCU module needed to be replaced. The vehicle was not repaired. The dealer was made aware of the failure. In addition, the contact stated that the dealer ordered the parts two years ago. The contact was informed that the parts were on back order and the parts were not available. The contact received a recall notification NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic) however, the parts were not available. The manufacturer was made aware of the failure. The contact was advised to take the vehicle to the dealer for diagnostic testing and provide a diagnostic fee. In addition, the contact was informed that the parts were not available. The failure mileage was approximately 86,000.

2nd time truck has warning lights on related to ABS, electronic braking system with no parts available from manufacturer - HCU. Truck is set up to tow a gooseneck trailer. Loss of braking capacity has put me in hazardous situations as the problem is intermittent. Previous repair, where dealer stated my rotors were bad with fewer than 20k miles, was expensive and tech said it could be related to the electronic braking system failure causing rotors to malfunction. No remedy from manufacturer is unacceptable as I'm unable to use my vehicle and if I did, I could be in a situation causing a major accident with no brakes.

The ABS system has deactivated along with traction control and all the lights are on the dash with a message that says service electronic brakes system. Stellantis claims that I am not included in the recall even though my model year and model match others being recalled and the part needed to complete the repair is the one that is being redesigned because the original one is faulty. Please help!

I am filing this complaint regarding the unavailability of a critical safety component for my vehicle. Multiple dealers have informed me that the part is not available through the Mopar parts chain. However, the identical part is currently available for purchase by consumers through MoparGenuineParts.com (111 Bond Street, Westbury, NY 11590) at the following link: [XXX] ). One verified buyer even confirmed this discrepancy. As [XXX] wrote in his 5-star review dated 04/03/25: *"ABS PART – Fixed my problem just what I needed. Dealership said they could not get to because of part shortage??"* This highlights a troubling inconsistency: Mopar’s authorized dealer network is unable to supply parts that consumers can easily purchase online. It makes no sense that the official supply chain is cut off while direct-to-consumer sales remain active. The component in question is critical to the safe operation of the vehicle. If it fails at high speed, the driver could experience sudden loss of braking or steering control. Such a failure poses an imminent danger of severe accidents, rollovers, or fatalities, both to the vehicle occupants and to others on the roadway. My concern is twofold: (1) why Mopar dealers cannot access parts that clearly exist in Mopar’s system, and (2) how long-term safety is being compromised if consumers must resort to inconsistent third-party availability for essential components. This disconnect directly threatens public safety. I respectfully request NHTSA investigate why Mopar’s dealer network is unable to provide critical safety components, while consumers can obtain the exact same part online, and whether this practice constitutes a systemic safety hazard that warrants recall, investigation, or enforcement action.

The truck has had the HCU not working for at least two years, with no success at repair due to part unavailable. Truck has low miles due to the brakes being a safety concern. Reached out to RAM customer care several times with the response being parts unavailable. January of 2025 a case number was issued !00Dj001qsDF.!5007y0tkhWy. We had been notified of the recall Jan 2025 and told parts would be available April 2025. Contacted 3 RAM service departments, and no parts are available.

Abs light continuously cycles. Front left brake is very hot

The ABS brake system control module HCU is failing vehicle is available for inspection I’m not sure if the brace are going to work or not the traction control is affected. Vehicle is not safe to drive long distance. The vehicle has not been reproduced for a dealer or independent service center. It has not been inspected by the manufacturer or the police or the insurance representative or any other Agency? I was driving along when I got the notice on my dashboard. My ABS module was malfunctioning and then it quit malfunctioningand then it started malfunctioning again, right now it is back-and-forth at random. A call to the local dealer service rep said that the parts not available and they do not know when it will be. My concern is it safe to drive or not?

I am filing this complaint regarding an unresolved safety recall for the Hydraulic Control Unit (HCU) on my 2017 Dodge Ram 3500, VIN ending in [XXX] , under Recall Number C4B/NHTSA 24V-896. We received the recall notification months ago and have been waiting ever since for further instructions or a remedy from FCA US LLC. After more than six months, we still have no resolution. Recently, the vehicle was towed to Patterson Dodge in Tyler, TX, where it was inspected by the dealership. They confirmed that there is currently no remedy available for the HCU issue and stated they have no idea when a fix will be provided. This is not just a matter of inconvenience — this is a critical safety concern. FCA's own recall notice clearly states: “The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning.” We purchased this truck specifically to tow our 5th wheel camper, which we now cannot safely operate due to the safety risk posed by this unresolved recall. Without proper braking and stability control systems, towing a heavy load would be incredibly dangerous, not only to us but to everyone else on the road. We understand that vehicle recalls can take time to resolve. However, it is extremely concerning that: FCA has offered no timeline or remedy after many months. The vehicle remains inoperable for its intended purpose due to the unresolved recall. We were never proactively contacted with updates and had to follow up on our own. The dealership confirmed the part is not only unavailable but with no estimated time of arrival. We respectfully request that NHTSA investigate whether FCA is meeting its obligations under the National Traffic and Motor Vehicle Safety Act to provide a timely and effective recall remedy. A known safety defect has been identified, but the remedy is indefinitely delayed, and the manufacturer is not offering alternative solutions (loaner vehicle, buyback, etc.) while we are left with a vehicle we cannot safely use.

Needed to use brakes but unexpectedly the pedal did not work or stop the vehicle. Had to swerve into a ditch to avoid a collision with another vehicle. Abs, traction lights then activated.

FCA issued recall C4B notification at the end of 2024, with estimated parts availability in the 2nd quarter of 2025. It is now the 4th quarter of 2025 (almost a year later!) with no update on parts availability. Considering that malfunction of the braking system is a critical safety hazard, it is unacceptable that they have and continue to delay a timely resolution for those impacted.

The ABS module has not worked for over a year. To me this isn’t a timely response. What are my options?

I own a 2017 ram 3500 that has had ABS brake problem, been trying to fix for years they have no parts available. I don't understand how other people or getting trucks fixed but we seem to get put aside. I actually had two trucks with same problem had to trade the 2018 in with value loss for check engine light with ABS. I was give a case number but no dealers have contacted for repairs. Case 92030267.

Defective HCU. 2015 Ram 3500 single rear wheel 4 wheel drive with 40,000 miles. ABS light, ESC/Traction Control codes and dingers started in 2020 at 28,000 miles. DTC code indicates defective HCU. Several dealerships have been unable to address repairs due to updated parts unavailable from FCA. This vehicle with known defective braking system has been restricted to local errands for 4+ years for safety reasons while family camper remains stored.

Service antilock brake warning is intermittent. This has been traced to defective pump/control modules. Parts are unavailable.

This issue is related to 2017 Ram 3500 truck with 6.7L Turbo Diesel motor: The warning lights for the ABS and the Cruise Control intermittently activate and there is an audible alarm ding noise along with them. This ABS warning light going off intermittently indicates that if a situation arises that requires the ABS system, it may not activate as designed. Which in turn could contribute to loss of control or accident with the vehicle. This problem has been confirmed by Villa Rica Auto in Villa Rica, GA. This vehicle has been inspected by Villa Rica Auto. They advised that the problem is with a defective HCU and that part is on back order with no ETA available. This problem first appeared a few days after buying the truck from Gravity Autos Atlanta. This truck was not involved in a crash.

My truck has 57,000 miles on it. Keeps getting "Service electronic braking system" and "ABS" message. "ABS" fault light and "Traction control" fault light comes on. Lights and message stay on for a couple seconds. Does this over and over. I had this problem before when the truck had about 20,000 miles on it. Braking system hydraulic control unit (HCU) was replaced under warranty. Contacted dealer service department and was told it was safe to drive, but abs may not work properly.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and Ram refuses to replace/repair it and I’ve been waiting a year. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. It also disables the cruise control and 4 wheel drive. I have contacted my local dealer multiple times and they have made no attempt to help me. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message. "

ABS system keeps beeping due to known defective part which Dodge has known about. My vehicle only has 27,000 miles on it

ABS module is bad. Didn’t last long and shut cruise control off. And makes hard to brake with trailers

ABS Module/HCU replaced 3 times defective yet again. This is a safety issue because Anti-lock brakes, traction control, and cruise control do not work

My abs and traction control lights come on and electronic brake service messages along with the chime Had the truck scanned by a personal mechanic and the abs pump is not working

Antilock brake module failure and no traction control. Also no cruise control. Having this problem for over two years, took vehicle to dealer and replaced valve in abs system. Having the same problem again for one and a half years now. Please fix.

Check engine light came on. Got a code C0020-01. abs pump motor control. Opon further research I found out this is a common issue and I was told to report it to nhtsa for there investigation. I did not have it fixed yet.
