2018 RAM 2500 Vehicle Speed Control Problems

I am submitting this complaint about Safety Recall C4B / NHTSA 24V‑896 for my 2018 Ram 2500 (VIN: 3C6UR5CL4JG333543). I am active‑duty military living in Virginia; the truck is registered in Tennessee. FCA’s recall notice says the brake hydraulic control unit (HCU) may fail, causing intermittent then permanent loss of ABS, ESC, and traction control, and that this “may cause a vehicle crash without prior warning.” My truck shows as affected, but I have been unable to get the recall repair. The notice also states that the remedy is “not currently available” and that FCA will contact me when it is. As of February 2026, more than a year after the recall was initiated, I am still being told that parts are unavailable and there is no firm ETA for when the repair can be performed. In the meantime, I continue to drive with a known safety defect FCA has...

This has been a recall for almost 2 yrs now and the dealer is saying no parts available. There are 1000s of RAM trucks driving around waiting for parts. A simple google search shows there are parts available on line. What is taking so long. This should have been resolved a year ago.

Received a recall letter Jan 2024 concerning C4B/NHTSA24V-896. I have contacted the FCA recall assistance center several times since then. They say there is no parts available for this recall. Yet they have not seemed to have this problem with 2019-2026 models. They say I can have the HCU replaced at my own cost and they will reimburse me for the cost. But there is no guaranty it will fix the problem or how long it may last if it does. This causes me problems because why should I have to pay nd Waite on my money to be returned to me in 60 days. I am retired and on Social security and can only afford to put this on a credit and which I would have to pay interest on. It seems you or FCA has any intentions of coming up with a fix for this recall.

My 2018 Ram 2500 has an active safety recall for the ABS/EBS system that has been open for over two years with no remedy or parts available. The issue was first noticed in August of 2023. I contacted CDJR dealership on how to repair this issue. This is a serious safety defect that directly affects braking stability, trailer brake communication, and emergency handling. Because the ABS module and electronic brake system are malfunctioning, the truck cannot safely perform the heavy towing it was purchased for. When towing a large trailer, the trailer’s electronic braking system does not communicate with the truck, forcing the truck to absorb the full braking load. This has resulted in unstable braking, increased stopping distance, and unsafe emergency handling at highway speeds. The ABS fault also disables cruise control, which significantly increases driver fatigue on long-distance trips. I regularly travel 1,500 miles each way to Florida,...

CB4 Recall Some (2017-2018 MY Ram xxx) vehicles may have been built with a brake hydraulic control unit ("HCU") that 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. Been dealing with this issue since the recall got initiated back in November 2024. I call Mopar every month to check on the status and still no parts available. I haven't had any brake failures in my truck or scares, but whoever has this issue has to understand how annoying the constant chime is. Can't use cruise control and worst thing is if you are considering selling your truck outside of a Ram dealer, they won't take it in because of the open recall and privately, who would...

ABS TRACTION CONTROL LIGHT HAS BEEN ON/OFF SINCE 2020. Can't drive on snow ice due to traction control abs 4-wheel drive doesn't work correct. I almost hit the divider/wall on Interstate 30 on 01/28/26 due from poor braking.

Dash warnings for abs / traction control flicker on and off steadily. Every time the warnings come off it kicks off cruise control. I live in often snowy conditions and I worry that steadily changing traction control systems will absolutely be dangerous. Not to mention the frustrating noises of the alerts coming on Avery few seconds. As I was told by my dealer, this recall has been out there since December of 2024. I’ve been dealing with this issue for months and it is getting worse.

I own a 2018 Ram 2500 equipped with the 6.7L Cummins diesel engine that I purchased brand new in Iowa. For approximately the last four to five years, my vehicle has displayed persistent warnings including “Service Electronic Braking System,” ABS warning light, and traction control warnings, accompanied by constant audible alerts. As a result, multiple braking safety systems are disabled, including anti-lock braking, stability control, traction control, and cruise control. For several years I contacted Ram dealerships and the manufacturer regarding this issue and was repeatedly told that repair parts were unavailable. During this time, widespread reports of identical failures were being discussed on owner forums and among dealerships. A federal safety recall was eventually issued for the ABS control module, and I received my official recall notification letter approximately one year ago. Despite the recall being active, the manufacturer and local dealerships continue to state that no replacement parts...

The contact owns a 2018 Ram 2500. The contact received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that the ABS and Traction Control warning lights were illuminated. While attempting to use the cruise control, the system failed to activate. The dealer was contacted. The manufacturer was made aware of the issues and confirmed that the remedy was not yet available. The failure mileage was approximately 118,000.

Recall/Campaign: Ram/Stellantis C4B Problem: “Dealer says remedy/parts are not available / cannot schedule recall repair.” This has been a problem since 2023. Have not had ABS for years or 4x4 and i live in a snow environment. My breaks and rotors are trash from not having ABS.

My 2018 RAM 2500 has had an ABS system recall since Nov 2024. My truck has had a problem with the ABS since 2019. I do not have anit-lock brakes or cruise control as a result of this failure to be able to resolve the problem. Over a year since the recall, and still no parts available. How long is the NHTSA going to let RAM get away with this?? Maybe after some has an accident or hurts someone they will respond. I have been a RAM owner since 1989 since the first CUMMINS engine was put in their 2500's. I'm VERY disappointed in RAM, and the NHTSA for not resolving this.

I am the owner of a 2018 RAM 2500 that is subject to NHTSA safety recall 24V-896 (manufacturer recall C4B), involving a potential failure of the Hydraulic Control Unit (HCU) affecting ABS, electronic stability control, and traction control systems. This recall has been active for over one year on my vehicle. Despite repeated contact with authorized RAM dealerships and the manufacturer, I have been informed that no repair remedy or replacement parts are available, and no timeline has been provided for when the recall can be completed. This is a brake-related safety recall, and the continued inability to repair the vehicle creates an ongoing safety risk. The manufacturer has not provided an interim remedy, loaner vehicle, or alternative solution. I am filing this complaint to document that the recall remains unresolved due to parts unavailability and to request NHTSA review of the extended delay in providing a safety remedy.

Early 2024 and it continues today, I randomly get an alert about my braking system needing checked but then the message will go away and everything works fine. I finally took it to Keer Automotive dealership in New Lexington OH in March 2024 to see what was going on and they advised there was an issue with the ABS module and the part wasn't available but they were expecting it in May 2024 and it would cost about $1800 for the repair. They put me on their list to contact when they received the parts. Around November 2024, I received a recall notice. To date, I am still waiting on the part. I continue to follow up with Keer but they have no answers. In the meantime, I am stuck with a $65,000 truck that has a faulty braking unit. It is my mode of transportation and with winter upon...

Stellantis and RAM companies have had Manufacturer Recall NumberC4B NHTSA Recall Number24V-896 Recall Status: Recall Incomplete, remedy not yet available This has been well over a year and I have lost the use of my Truck for loading my Truck Camper for the entire year due to their lack of resources allocated to fix this issue. I have had the Traction control light /ABS Service light associated with the HCU electric pump motor fail on this recall since June of 2024 and it is due to defective parts that do not last as this was the second HCU/Electric pump motor in the truck from the Manufacturer and installed serviced by my local RAM dealer dealer( first one failed at 11,500 miles approximately. my truck has 23,000 miles on it currently as and when the repair part(s) come into stock, it will be the 3rd unit installed. This time on waiting...

I have a 2018 ram 2500 purchase from the dealership within the same week of purchase magically the ABS system failed driving down the highway in the middle of winter time kicking out cruise control and traction control causing me to almost crash on the highway and get hit by a semi Not only have I had the truck for almost 2 years unable to drive it I believe the dealership should never been able to sell me this vehicle with the known problems and what they already failing ABS system making me unaware of the issue Yes and the brake system not working in the truck sitting has caused other failures in the vehicle now a transmission shop told me the ABS failure affecting other parts of the truck caused the transmission brain to not work correctly and my warranty could not fix the transmission is corrected and fixed...

Traction Control and ABS not working properly. ABS light on dashboard is on called dealer several times and am told that the parts are unavailable. However, they said if I want to pay for the parts they could fix it. We called mopar and were told that the parts are available and can even be purchased on [XXX] . Called and explained this to the dealer and they said they had 1 in stock and made an appointment. Then received a call that they didnt know if they could get the parts - seems like if I want to pay out of pocket they will fix it. I would like to know if I lose my brakes or have an accident because of this safety issue who will be responsible?? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

24v896-unit has been coding for months, dealership or chrysler have no fix in site. this is a safety hazard and I need my unit for daily driver and have been without for more than 3 months with no solution. I need them to replace this unit with a new unit or buy it back for the price of what it would cost me to get a new one. I need to have a truck to use if they are not going to repair it. I need this now.

abs and traction lights stay on. cruise control does not work. recall is 24V-896 and parts are still not available after almost a year.

RECALL ISSUED NOV 2024. PARTS STILL NOT AVAILABLE FROM MANUFACTURER BUT CAN ORDER THEM ONLINE FROM THIRD PARTY. ABS AND STABILITY CONTRPL LIGHT STAY ON CONTINUOUSLY, ALSO PREVENTS 4WD FROM WORKING AND CRUISE CONTROL. THIS IS A DAILY DRIVER FOR WORK AND IS A 7 YEAR OLD VEHICLE. WHY CAN WE NOT GET THIS FIXED. CANT GET A RESPONSE FROM MANUFACTURER.

Recall C4B/NHTSA 24V-896 Hydraulic Control Unit ABS. Continual tripping of the ABS warning resulting in loss of ABS, Cruise Control, Traction Control. Each trip give a warning and chiming resulting in nonstop alarms, noise and loss of the above features. It has been a year since the recall, over two years since the first class action and still no remedy to this safety issue. It is time for the NHTSA to sue and obtain a consent order from FCA similar to earlier FCA consent orders to repurchase these vehicles as they are currently unsafe to drive, there is no remedy in sight, and the resale value has plummeted as a result of this recall and lack of remedy.

Since the recall was announced, my truck has experienced constant ABS and traction control alarms, including an unending beeping warning chime that makes the vehicle unpleasant and unsafe to drive. My local Ram dealer confirms that the repair parts (HCU/ABS module) are not available and that there is no estimated time frame for replacement. This situation has now persisted for months, leaving me with: •A continuously beeping alarm while driving or idling, •A loss of confidence in braking and safety systems, •And a significant loss in resale value, since I cannot sell or trade the vehicle while this open safety recall remains unresolved. Impact This recall defect has made my vehicle effectively undriveable and unsellable. I have made multiple attempts to have it repaired, but the dealer and Stellantis representatives continue to tell me that parts remain on national backorder. As a result, I am deprived of the safe and...

The ABS system continuously dings and the cruise control will not work and shuts itself off due to recalled defective part. Waiting for new recall part!!!!!!! Why was a recall issued with no part to fix??? Make them get their act together. This is dangerous and maddening to listen to constant bell ringing in the vehicle. Not to mention the possibility of an accident. This vehicle is my daily driver. I need the vehicle to be operational and safe.

Recall 24V-896, cannot be repaired, no repair timeline in site, vehicle is coding and dealership has confirmed code. Driving cruise will turn off and braking system becomes difficult and unstable. Warning systems come one. Dealership attempted to repair but manufacture advised they were not allowed to do so because it would not be permanent. Dealership has advised to park unit and contact Chrysler for buyback. We have called Chrysler customer care daily for 3 weeks with no success and no end in sight. The will not provide daily driver solution, vehicle replacement or repair fix. This is part of our daily driver to and from work and to and from farm to carry trailer with cattle. It is unsafe without proper braking system functioning and dealership has confirmed this and advised us to not operate. Chrysler has also advised us to not operate since it has coded but has offered...

My HCU has failed and now I don't have anti-lock braking, electronic stability control, traction control, or cruise control. I have contacted Mopar and two Ram dealers in my area but they just tell me there is no remedy. This has been going on since December of 2024.

Brakes went out abs/traction control/tpms lights on. Brake pedal goes to floor 50% of the time. Have to downshift and use engine brake to stop.

Vehicle is subject to safety recall for malfunctioning HCU. Frequent illumination of Anti-Lock Break and Traction Control Warning Lights with accompanying Chime and loss of Cruise Control function. When illuminated, vehicle rear wheels will slip and braking is degraded. Illumination of Warning Lights and chime very distracting. FCA initially estimated repair parts available first quarter of 2025. This has passed and no updates are available from manufacturer. This is an unsafe condition.and I request NHTSA intercede on behalf of the 300,000+ owners affected and seek clarification from manufacturer on when they plan on honoring this recall.

Logging a second complaint for the brake hydraulic control unit that is already recognized by FCA as a defect that needs to be replaced. I am two years into this failed unit and continue to be told by the dealer and manufacturer's customer service that the replacement part is not available and they do not have a delivery date for this part. In the last two years I have had (4) near collisions as a result of no anti-lock brakes and no traction control. Additionally the cruise control is not active when this part fails and as a long-distance driver this is fatiguing. The contant dinging of the warning light and bell is extremely irritating. The reference number for FCA's recall is C4B/NHTSA 24V-896.

ABS INTERMITTENTLY ALARMS VERY FREQUENTLY AND CAUSES THE CRUISE CONTROL TO DROP OUT. I ASSUME THE ABS IS USELESS AND THIS TAKING PLACE. I’M TOLD THIS IS A COMMON PROBLEM.

HCU has failed on my truck back in July of 2024 it was impossible to find a replacement part got a recall letter on November had abs track control, and cruise control loss repeated dinging sounds to service ABS and electronic brakes and most recently you can hear the brake pads slightly rubbing on rotors and can feel a little bit of resistance while driving down the road

Truck will not shift and drops out of drive leaving you helpless

August of 2023 I had my service electronic braking system, abs, and traction control light come on. Dealer diagnosed as bad hcu. As of today 2-4-25 I am still waiting on parts with no answer as to when parts will be available for the repair.

I am filing this complaint due to a GREAT safety concern with my vehicle. I am a law enforcement officer as well as a firefighter. I was notified that there was a safety recall on my vehicle. The recall was for the hydraulic control unit ("HCU"). One of the risks of said recall is the loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning. After being notified about said recall, I notified several Ram Service locations in my area as well as the surrounding areas of where I reside. Each and every one of the service personnel or advisors I spoke with told me “there is not a remedy for the recall as of yet due to parts not being available.” When asked what I needed to do at that point, I was told to continue to drive my vehicle. Each dealership I spoke with stated they...

I'VE BEEN OPERATING MY TRUCK SEVERAL TIMES NOW WHERE THE CRUISE CONTROL HAS WENT OFF OR DISENGAGED WHILE DRIVING, CAUSING A SLIGHT PANIC FROM NOT KNOWING WHAT WAS GOING ON IN THAT MOMENT. THIS HAS ALSO HAPPENED WHILE TOWING, WHICH MADE THINGS EVEN WORSE. MY CRUISE CONTROL IS NO LONGER WORKING AND NOW I AM DEALING WITH THE RECALL WHERE THERE IS A "REMEDY NOT YET AVAILABLE". THIS WOULD BE RECALL MANUFACTURER NUMBER C4B AND NHTSA RECALL NUMBER 24V-896. I BELIEVE THIS RECALL TO BE TIED IN WITH MY CRUISE CONTROL ISSUE. NOW I HAVE A TRUCK THAT I HAVE NO OTHER OPTION THAN TO OPERATE AS MY DAILY DRIVER; WITH NO CRUISE CONTROL, ABS/ECS/TRACTION CONRTOL. I'VE CONTACTED SEVERAL DEALERS TO SEE IF THEY HAD ANY INSIGHT AND I HAVE BEEN GIVEN THE SAME ANSWER ABOUT THERE NOT BEING A 'REMEDY'. I WANT IT TO BE KNOWN FOR LEGAL PURPOSES...

Hydraulic brake unit failure. yes part is still available for inspection as it is still n the vehicle. I was driving to work at 21:30 hours on 1/1/2025 on a snow covered road. I gently applied the brakes and my truck went into a spin. I was going 25 mph. the abs unit failed and there was no pulsating in the brake pedal and rear brakes locked up sending the truck into an uncontrollable spin. my front left driver side of the vehicle then struck the jersey barrier and vehicle did continue to spin and then struck passenger rear side of the vehicle on the jersey barrier. currently has $17k in damages to the vehicle. I was not injured at the time but currently experiencing lower back pain. there was no lights or warnings on dash until immediately after the collision. I had the ABS HBU replaced a few months...

My abs control warning goes on and off and will not allow me to use cruise control and is constantly beeping at me.

My truck has 85000 miles on it. I have now experienced the ABS and traction control warning lights. They come on and off intermittently. The cruise control does not work when these lights are on. With all the complaints, its time Ram issues a fix under a recall.

My brakes locked up due to the abs pump not working.

Abs/hcu on the braking system has failed twice in the 3 years I've owned this truck.

The abs module has gave me issues and now has gone completely out causing no brakes and while it was having intermittent issues causes no cruise control and causes transmission issues which is another thing the transmission has went out again after this is the 3rd time replacing at around 10k everytime

in 2022 the abs and traction control lights began to come on together, leading to loss of ABS and traction control in addition to not being able to use the cruise control. Vehicle was taken to the dealer to be serviced and they stated they would replace the HCU but would not replace the ABS module as they would only address one thing at a time. The problem continues to persist with the constant alarm ding and loss of abs and traction control as the lights continue to flash on the dash. This is a safety issue as you don't know when you'll have abs or traction control and if it happens while driving with the cruise control on, it abruptly shuts down the cruise control.

The warning lights for my ABS and traction control come on and off while driving normal driving conditions. Every time they flash it also has an audible ding that is very distracting. If I am using the cruise control when this happens the cruise control will turn off. The ABS system does not work when the lights come on. I am afraid I will be unable to stop. I took it to a local dealer and they confirmed that the HCU unit is defective and needs to be replaced at a price of $1300.

While driving the service ABS System/ Traction control dash warning message appears on the screen & chimes at the same time. The cruise control then shuts off. At first it was intermittent then it was almost all the time. With winter coming soon the ABS/Traction control will be much needed. After going online, it seems like this is a common problem with 2017-2018 Rams. After going to a Ram dealer in my area they replaced the HCU/ABS pump. I feel that if this is a common problem it should be addressed with a recall to avoid potential vehicle control problems

Warning lights for ABS and traction control coming on with message to 'Service Electronic Braking System'. During this time the ABS does not work and cruise control stops working. Being a 2500 vehicle, it is commonly used for towing trailers as it has a towing capacity up to ~16K lbs. Suddenly not having ABS and traction control is dangerous. In July 2024 I was driving from Phoenix, AZ to East Texas with a ~10K lbs trailer and this issue suddenly started popping up. This is the first time I experienced this with this vehicle. I understand there is a known issue with the hydraulic control unit and the ABS modules for 2017-2018 2500 & 3500 models yet there has been no recall on these vehicles.

The ABS dash light and traction control light started coming on about a year ago. the light is intermittent with a ding sound. Some days it comes on non stop, sometimes it doesn’t come on at all. cruise control does not work, and “park rear” button is not able to get out of the off mode.

Driving on interstate highway with cruise control engaged. Experienced rapid deceleration as cruise control disengaged without driver input. Received anti-lock braking error / service electronic braking system error. Was very dangerous situation to have occur unexpectedly and could have easily resulted in rear end collision or loss of control of vehicle. Received no warning prior to this failure. Issue has been sporadic but occurring more frequently. Vehicle has less effective braking in adverse road conditions. Never know when the anti lock brake system will be functional. A bump or vibration in the road can cause it to engage or disengage. Ram dealer service dept indicates Hydraulic Control Unit needs to be replaced. Looking online, I see this is an exceptionally common occurence in same year/make vehicles. So much so that the replacement part is backordered for months.

It's clear that my abs module is bad but it consists of three components. Mopar online doesn't have any components available to fix the problem. And the Dealer is selling the components separately and telling you which one they will sell you first and also at a higher price than what's available to you online

ABS/traction control warning lights and alarm intermittently on and off during driving, speed control does not work during the alarm cycle. ABS not working when warning comes on

While driving the PU with my camper in tow, the ABS and Service electronic bakes system warning were displayed on my dash. Then they went out. This process repeated several times over the next 3-4 minutes. Then the warning lights came on and stayed on. It remained that way until I parked on the side of the road and turned off the vehicle. I checked the undercarriage for any signs of any visible damage to the braking system. None was readily identifiable. Upon restarting the vehicle, all warning lights were extinguished. I proceeded to the campgrounds with out further warnings on this system. The next day, with out the camper in tow, the warning lights were again active flashing on and off for a period of about 3-4 minutes before they again came on and stayed on. This process repeated itself as I would turn off the vehicle and then...

ABS and TRACTION CONTROL warning lights appear and disappear. Timing of warning lights have no discernable pattern. Vehicle has had no collisions and only 120,000 miles. Vehicle will be going in for inspection at garage.

Abs module failure causing cruise control shutdowns and potentially causing an accident as well as transmission issues. Yes it’s been confirmed by an independent shop . Not by any others. No warning before just straight failure. Vehicle is available currently for inspection if wanted
