2017 RAM 2500 Service Brakes Problems

The HCU for my truck failed and was replaced 6/25/2021. It failed again 12/2024 but before it could be replaced a recal for the HCU came out with the warning "The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning" Now the warning light keeps coming on and going off with the alarm sound as I drive. It also turns off the cruise control. This has been going on for well over a year with no date for a fix of something that can cause a crash without prior warning. There doesnt seem to be any urgency to fix something that can cause such a big problem. I have no choice other than to keep driving my truck hoping for the best. Any help with this is most appreciated. Thank you for your time, G. May

C4B 2017 Ram D2 DD DF DJ DP Hydraulic C / Not Available We are at Risk everyday Yes Confirmed Recall and Problem Yes inspected by Ram Dealer & CarMax The warning lights and the noise constantly goes off and they’ve been happening since a few days after we purchased the vehicle and the dealership that we purchased, the vehicle knew about the problem and never fixed it until this recall which they’re still not fixing for us. I am going to file a lemon lawsuit. Unless they solve this issue. $40,000 Vehicles should not have these issues. The brakes are locking up and almost crashed several times . I can forward the receipt from the dealership, but it’s not letting me upload it on this page.

Hello, I received a recall notice "C7B" from FCA. Checking with my dodge dealer they said it has been completed. Problem is I never had this done. FYI, I have had past problems with this break system and it had been replaced I think 3 time, but no recall had been issued before all this. Anyway I contacted FCA and they now have given me the updated recall notice called C4B with no resolution or repairs and referred me to arbitration.

My ABS light has been on for 2 years. It was previously diagnosed as the ABS pump/module. The parts were on backorder. The C4B Recall came out over a year ago. There is still no parts available. My truck is at the dealer right now and they said they can't do anything with the Recall. I figured they could at least verify the failure and put in an order for the part. This a big safety issue for tons of RAM owners as most of us bought these trucks to tow and haul heavy equipment, trailers etc.. I am on several forums and everyone wants to get these repairs completed.

HCU issue. My traction control light is on and dealer said some of the 2017 rams were covered but not mine. I looked it up and there was a recall for the HCU’s

While driving the anti-skid anti-lock failure light flashes with an audible warning. This has routinely been happening since early 2025, with the only local dealer advise is to rapidly depress the gas pedal with the key on (engine off). There’s been zero advancement to provide remedy to date. When I ask the dealer, he says “we haven’t been notified yet of parts being available. You’ll be notified when we get to okay. This is in reference to safety recall 24V-896.

I have called & been to Fletcher Chrysler in Franklin, IN and they said that there is still no remedy/fix for the brake recall on my vehicle. I use it to tow our 5th Wheel & am seriously worried about towing it in the Spring, as well as daily driving in around. It has now been 14 months and there still is no repair for this Recall issued in Nov 2024.

Received a re-call letter from FCA US LLC back in November of 2024 stating there was a re-call for the HCU which will affect the ABS as well and the ESC. ( Letter attached). Upon receiving the letter, I immediately ( with a day) starting calling around to dealerships to get it fixed, and not one was able to help me. Stating the part isn’t available, which was odd as I just received the letter. So I was thinking maybe I called to soon. I called once a month, every month since November 2024. Thinking this would be enough time to find the part, or find a new company or have the part fabricated some how? After months of no luck, I called Mopar/ Fiat. I was told the company that makes the part is no longer in business and when I asked about any other company making this part,...

I was pulling my gooseneck trailer with equipment on it and had to stop quick because car pulled out in front of me an when I pushed the brake pedal it was very hard to push an my exhaust brakes did not come on an I noticed check brakes light an anti trac light were both on.exhaust brake was turned on in full exhaust an exhaust light on dash showed it to be on but exhaust brakes did not start working so I had ended up leaving the highway an going through a ditch so I wouldn't hit the vehicle in front of me an hurting or killing someone or myself,luckily it wasn't a steep ditch so I was able to make it down to the service road down below without any injuries or damages to my truck or trailer or equipment, I've call several times once I recieved the...

This is in regards to Recall #C4B for the ABS/HCU failure on my 2017 RAM. This recall was issued over a year ago in November of 2024, but Stellantis has yet to DO ANYTHING and can't even tell us when a remedy will be available. I have asked my local dealership and get the same answer, NOTHING!!! The parts must be available, because the dealership told me that I could purchase the part from them and pay them to install it. But, I would have to then wait to get reimbursed from Stellantis once the recall is "remedied". Two problems with this; 1) I don't have the $1500+ to spend on this, and 2) I don't trust them to ever pay me back! But, this does tell me that they have the parts. Plus, they have no trouble making and selling new vehicles with parts that don't have this safety...

2017 Ram 2500 Laramie Crew Cab , 4x4, 6.7 Liter Cummings A/T. Receiving a “Service Electronic Brake System Soon” warning light intermittent after start up since at least since June 2025. Code reader advises to replace “HCU” Hydraulic Control Unit, ABS Module. My vehicle was produced 03/2017, however the ram recall is from vehicles produced from April 2017. Seems they are excluding other production vehicles for the recall replacement of the improved ABS HCU Module.

I have been waiting for these recall parts for nearly a year or better. I'm not able to safely drive my vehicle or inspect it. It has been far too long and my vehicle sits in the garage with 49,000 miles on it. I can't move it, drive it, sell it, use it. I think chrysler should be made more responsible for the losses of many many people and this part for their vehicle. I contacted the AG's office and they recommended I file a complaint with you folks. Please, please help!

ABS Module and or HCU finally quit working. Loss of cruise control, ESC (traction control), 4x4 and speed sensor not registering. Had now storm around the 1st of December and got stuck on road in front of house due to loss of traction control and 4x4 not engaging. Dealer had said 4x4 was working when they informed me the ABS module needed replacement. It currently at a private diesel repair shop and they confirmed the ABS module needs replacement. Currently awaiting a ship and repair service to see if the module will work and fix the loss of above. There were two warning lamps on the dash lit up. The ABS and Traction Control light. I am hoping that all I need is the module repaired and that I don’t need the HCU replaced. This is super frustrating because there is a recall on the parts but the dealer and...

One instance all the brakes locked up on dry pavement. Second instance the brakes were slowing the truck on a wet surface but would not stop and did not engage the antilock brakes properly. 3rd time brake locked up just on right front wheel.

The recall was issued over a year ago and still no remedy.

I have code C0020-01-ABS Pump motor control on in my 2017 Ram 2500 for almost two years. I bought it used at a dealership in Maryland in June 2022 and each time I check with them, the part to fix it is backordered or not available. According to a Star online publication dated 4/28/20 from FCA, when this code is on the HCU and the ECU should be tested and replaced, but the abs module is on parts restriction. Also, NHTSA ODI (NEF-102ig PE22-012) sent a letter to Head, vehicle safety compliance FCA, on January 23, 2023, notifying them that NHTSA had opened a Preliminary Evaluation to investigate allegations of intermittent or permanent loss of braking performance in my truck type and year. I feel this is a severe safety Hazzard and a fix to repair should be immediately available, and a recall issued so the solution is free of...

The abs braking system failed and the truck was put in an uncontrolled skid where the brakes completely locked up and crashed into another car. The cause severe damage to 2 cars. I reported it to the dealership and they don't have a fix for it. There were no warning lamps prior to the collision and none are up now.

NHTSA Recall Number24V-896- HCU unit replaced once. Replacement unit has now fully failed. Dealer Dutch Miller Ram of South Charleston made positive diagnosis of failed unit [see attached]. Same dealer notes NC replacement HCU part is not available. Same dealer notes however for a charge of @$1100 Stellantis has replacement units available for installation with a part # separated from remedy part by a single digit. The warning chime causes distracted driving as warning light and chimes occur persistently intermittently. This unpredictability requires driver eyes and attention to confirm cause of warning! Recall letter received early January of 2025!

My truck will lose all throttle response and brakes harder to stop accompanied by a service electronic brake system, service electronic throttle control, and electronic traction control warning. It only happens intermittently and sometimes will go a few weeks before doing it again. (The date below for incident is latest date it happened)

This is related to recall C4B/NHTSA 24V-896. The ABS/ESC/Traction control warning lamps come off and on while driving. The recall states that this issue may cause a vehicle to crash without prior warning.

Continuous warnings and tones showing issues for anti lock brakes and stability traction control. In less than 3 months will be a year since the recall was announced and there is no remedy. This is a nuisance and safety issue and should absolutely be a priority to fix. NHTSA #24V-896

This is my 2nd NHTSA complaint regarding this issue on my 2017 Ram 2500. Initial online complaint was done on 4/30/2022 regarding the trucks annoying and unsafe warning light indicating “Service Electronic Braking System” and amber ABS warning light. These warnings began on my truck in 2021 when it only had 12,000 miles. These intermittent warning lights and audible “dinging” still persist today at 22,000 miles. On 2/8/2025, I received notification of Recall #C4B (finally) as a result of the class action lawsuit and was pleased to see this development. To date, I, like many Ram owners are still awaiting parts to become available to have them replaced per the recall and am requesting that the NHTSA step in to assist as we all have essentially unsafe trucks on US highways. I believe this should be a priority, given the fact that owners of 1500, 2500 and 3500 trucks often...

As I approached stop sign and applied brakes the ABS and traction control light came on. My truck then started surging up and down As I attempted to proceed thru the red light my truck stalled and shutoff an on coming car had to stop aggressively to avoid hitting me

I received notification of Manufacture Recall C4B (NHTSA Recall 24V-896) in Nov 2024. My intermittent ABS light on my dashboard is continuously going on and off, indicating a problem with the anti-lock braking system since 2024. This prevents the setting of cruise control as well as a constant alarm sound. I feel this directly correlates from the brake hydraulic control unit HCU susceptible to failure or malfunction as stated in the recall and feel unsafe to drive my vehicle due to the potential risk of loss of ABS/ESC/Traction control that may cause my vehicle to crash without prior warning. I have attempted to remedy this situation by contacting the Washington, NC and Greenville, NC Dodge dealerships and Mopar Parts Support (800-765-7732) directly for immediate repair only to be told that they do have my information on a ticket but do not have a part to fix it, but in the...

Truck has ABS and Traction control lights kicking on and off intermittently. Cruise control will kick off if engaged and won’t re engage until the lights go back off. Concerned this is gonna be a major safety concern hauling a 10,000 lb trailer

I was notified about a recall (NHTSA 24V-896) with the HCU being susceptible to failure around 1-15-2025. They have yet to fix the problem. They claim they are still working on a fix. I had the original replaced at 7336 miles and now the second unit is sending "check ABS system" lights. It has been 6 months of "chimes and warning lights" and they still claim they do not have a fix yet. Are they even trying to fix the problem or trying to figure out a way to get out of doing it. I would like to NHTSA to look into this matter and urge RAM to fix their manufacturing problem.

When I have gone to slow down and try to stop, the vehicle has slide forward a fee times. I thought it was a little weird, but didn't think to much of it. After a while, my transmission started acting up as well. I will be driving down the road about 50-60mph and it will shift to 4th gear and not come out of 4th gear until stopped and shut off and restarted. I recently heard about the recall when I took my truck to the dealership that is close to where I am located at the moment. I decided to research about the recall and what could happen if that part fails. It showed me that if the recalled part fails, it will cause all the problems that is going on with my truck. I am a full-time rv'er and trailer the country pulling an rv everywhere I go....

Antilock brakes module failed part is unavailable for 6 months I am wondering why it is not being recalled

My HCU has failed resulting in loss of traction & locked steering wheel. The truck is not safely operable at this time and dealerships have repeatedly told me they can’t fix it. This has been going on for 2 months.

Today I was attempting to come to a complete stop as the light was turning yellow but my brakes were hard to push down and eventually I ending up passing the red light and went gliding through the street. Thankfully no vehicles were passing or oncoming. It was a very horrible experience to have, I no longer trust the car to go on freeways as I am terrified to crash.

As I was driving back home from the airport on [XXX] both front brakes started smoking and my vehicle became noticeably difficult to drive. At the same time an ABS brake warning light came on as well. Although the vehicle was more difficult to drive I drove slower to prevent a crash & arrive home. On [XXX] I brought my vehicle into Midas Sarasota where they diagnosed a failed brake hydraulic control unit (HCU,ABS pump). In addition Midas stated that the failed hydraulic control unit damaged both front calipers causing them to stick which is why my brakes were smoking. Midas also stated that the failed HCU caused damage to the mesh in my brake lines and that they had to be replaced. As a result of the failed HCU Midas had to install a new HCU, install new front calipers on both sides, and install new brake lines for...

Can not get the dealership to repair the recall c7b. Stating the parts are not available. Been several months waiting on parts and scared to drive my truck due to the danger?

My vehicle is under the Manufacturer Recall # CB4 (NHTSA Recall #24V-896) On January 1, 2025, while driving on a rural road, all the warning lights for the ABS and Traction Control systems lit up and I lost all braking power. I pushed the brake pedal to the floor, no brakes. I veered off into a field to stop the vehicle. Turned the vehicle off and back on. Still no brakes. I started to drive the vehicle to my house (3 miles away) and after a right turn the brakes locked. The Ram Recall center apologized for the incident and said I would be authorized a rental and gave me a case # but that there was no remedy for my vehicle. My 3rd call to Ram, the representative said they aren't sure if a rental is authorized, and that Ram would not cover towing my vehicle to the dealership...

My ABS and electronic braking system is doing the same thing that is covered in the ABS recall just issued for other 2017 Rams but apparently my van is not covered.

I was driving when m ABS system errored failure as I was preparing to haul horses. I completely lost traction behind. Accordingly my truck is now completely unsafe.

My truck is a 2017 Ram 2500 and is experiencing the same issues as those included in NHTSA Recall No. 24V-896. However my truck was produced before the April 1, 2017 range listed. I have replaced the HCU as recommended by the dealer on [XXX] at my own cost and this did not resolve the issue. The dealer says the control module is faulty, but Chrysler will not provide the part as they say the HCU I purchased is in the Faulty range also but they say that even though the part I purchased to correct the issue is under recall, my truck is not and they have not responded to my request to correct the issue. This is a safety concern as it affects ABS, TSC, Parking Assist sensors and most importantly prevents the vehicles 4WD system from engaging which is an extreme safety concern in the mountains of...

I’m concerned, as I expect many owners of 17-18 Ram 2500 are. Feb 23, while returning to my home, I lost control of my vehicle after breaking before entering left to right turn that I had been thru thousands of times. Less than 1 mile from my residence I applied breaks gently prior to entering turn. After applying brakes, they locked up and I was unable to control my truck. I slid sideways a few hundred feet and made contact with a utility pole. I have never felt so helpless while driving. This caused significant damage to my vehicle. Never had any ABS problems prior to this event. After vehicle was repaired (well over $20,000) I had problems with ABS - Cruise Control that repair shop could not fix. They sent to tire shop who also could not repair. Was advised to take to dealer. Vehicle was repaired with new...

ABS/TRACTION CONTROL lights on, the systems do not work and the NTSB knows this. Numerous recalls on different years and Dodge models yet you won't recall the 2017. IT IS A SAFETY ISSUE. [XXX] and issue a recall on ALL YEARS and MODELS, or are you in their pocket????? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loss of brake function

ABS/ELECTRIC BRAKING SYSTEM LIGHT... HAD ABS PUMP MOTOR and HCU REPLACED 2 TIMES WITHIN 28 MONTHS AT MY COSTS..LESS THAN 60K ON ODOMETER

I have read online that this is a common problem for Ram Trucks. The SEBS and ABS lights and alarm will start flashing and dinging- the result is Intermittent ABS and traction control lights, no cruise or 4x4. I have 38,000 miles. I spent approximately $1300 to have it repaired. When I was. At the Ram repair shop, I was told that the parking lot was full of similar Ram trucks with the same problem.So clearly there should be a recall.

Repeated ABS service message on dash. Light and chime turn on and off while depressing brake pedal, turning, hitting bumps. ABS module and hydraulic module were already replaced 20k miles ago for same issue. Code C0020-01

HCU/ABS modules have failed for the second time in 50K miles. While using Cruise Control at highways speed (70mph) in heavy traffic the warning lines and chime came on. At the same instance the truck started slowing down dramatically. Almost causing us to get rear ended. It was like slamming on the brakes, but without brake lights to warn cars behind me. I finally figured out it caused the Cruise Control to kick out. Now I am having to listen to the constant chirping of the chime. It even chimes when the truck is not moving!!! Let me ask this question.... Why is it that long ago NHTSA required Anti-Lock Brakes on all cars to improve safety? Yet, when that system has a systemic problem of failure on these trucks, it's no longer a safety related problem? Makes zero sense!!! I purchased this truck with 99K miles on it. These...

Abs module and pump motor need to be replaced but are on back order and can't be replaced. Vehicle is now unfit for operation.

ABS Light and traction conrol light started acting up. Brakes not currently sticking but will be sending for possible repair as this is a common trend with this vehichle from What I have reviewed online.

ABS traction control keep flashing on and off due to hcu problem

Abs pump intermittent light

ABS module failure

In July of 2020 my 2017 RAM 2500 ABS and Service Electronic Brakes warning lights began illuminating intermittently. My vehicle had 12,343 miles on the odometer at the time and was three years old. There was no noticeable change to the brake performance. The vehicle was brought into a RAM dealer for service which found code C0020-01 ABS Pump Motor Control-General Electrical Failure present with Starcase #S2005000004 instructing the replacement of the hydraulic control unit. This corrected the issue until August of 2024 when the above warning lights began illuminating again, intermittently, but in increasing frequency. The issue was diagnosed by a RAM dealer with the same code as above (C0020-1) and the recommendation to again replace the hydraulic control unit. My vehicle had 30,901 miles on the odometer at the time. The total for the service in 2020 was $984.89 and in 2024 $698.46 for the second replacement of...

The illumination of the ABS light and traction control light. The light actives intermittently. The reported problem from a vehicle code reader is “ ABS pump motor control general electrical failure”. With the lights illuminated, I am no longer able to use cruise control. Prior to the warning lights I noticed I was having to depress my brake pedal harder than normally at random times. No signs of brake fluid loss or leaks. The brake pads are in good working condition. I have not taken it to a dealer as I have read the replacement parts are on back order and there are multiple lawsuits pertaining to this issue as well.
