2018 Ram 2500 ELECTRICAL SYSTEM,SERVICE BRAKES

Service ABS light constantly alerting, every time I touch brakes. Loses cruise control. I called two local dealerships who tell me parts are unavailable. This is on recall, why aren’t parts available?

My ABS module has an active recall. I have replaced brakes and rotors in the front and rear. I have had to resurface my rear rotors due to the issue. My breaks are locking up and causing issues. I can't back up my trailer without my breaks locking up. The recall has been active for almost a year without a resolution. This problem is unsafe and people's lives are at risk. Something needs to be done. I can't even buy an aftermarket updated part to fix this issue. Thank you!

My vehicle has a recall for a an ABS control module which affects, the ABS system, traction control, and cruise control system. The cruise control system will randomly turn off when the vehicle is at highway speeds causing a momentary struggle to keep control of the vehicle. The driver information display in the gauge cluster will randomly flash an error message with an audible "ding" which is highly distracting while driving. At times, this warning flashes every 3-5 seconds and lasts for 10-30 minutes at a time making it very difficult to concentrate on driving the vehicle. The traction control system fails when the message flashes which has been a problem on wet roads. The dealership has acknowledged the recall of the ABS module multiple times and indicated the manufacturer has not made a fix available for nearly a year. The issues with my vehicle are becoming more apparent and frequent every week. This is the second Ram 2500 I have owned that experienced a failure of the ABS module. I began to notice the issues with this vehicle in July of 2023 and the frequency has dramatically increased in recent months.

ELECTRICAL BRAKE FAILURE WARNING

WHILE OPERATING VEHICLE THE ABS AND TRACTION CONTROL LIGHTS WOULD FLASH ON AND OFF AND MESSAGE SERVICE ANTI LOCK BRAKE SYSTEM. THEN SERVICE ELECTRIC BRAKE SYSTEM WOULD FLASH AND BEEP IN MESSAGE CENTER. AFTER FLASHING ON AND OFF MULTIPLE TIMES THE MESSAGES SELF CLEARED AND LIGHTS WENT OUT. DURING THIS IT IS HARD TO CONTROL THE TRUCK. CRUISE CONTROL NOT WORKIING EITHER.

The ABS and and electric circuit lights came on, on the dash. Then a week later my Transmission started acting up. I had it into the shop and they are saying the 2 are related. They have given me the paperwork showing how the code that comes up is from the recall and the paperwork showing it can trigger the transmission control module. The manufacturer made the recall back in December of 2024. They have yet to come up with a fix. Now we have a none drivable truck that has to sit until they find a fix. I am still making payments on this vehicle and they have nothing to say. We are almost coming up on a year, where is the liability?

While operating my 2018 Ram 2500, the Hydraulic Control Unit (HCU) failed suddenly and completely, causing the loss of: Anti-lock Braking System (ABS) Electronic Stability Control (ESC) Traction Control This failure occurred without warning, creating an immediate risk of accident. The dashboard illuminated warning lights indicating system failure. The most recent diagnostic, performed by Einspahr Auto in Brookings, SD confirmed that the HCU requires replacement. Previous incidents with the vehicle involved intermittent failures of the same systems, indicating a persistent and unresolved safety defect. The dealer has not indicated when a permanent fix will be available. Due to the ongoing safety risk and extended timeline for repair, I am requesting a manufacturer buyback at this time. Stellantis has not provided any acceptable fix which does not impose financial hardship while the vehicle remains unsafe. Impact / Safety Concern: -The vehicle cannot be safely driven. -Significant risk of injury or property damage due to failure of critical braking and stability systems. Requested Action: I request federal oversight and that Stellantis provide a permanent remedy, including: -Manufacturer Buyback – Repurchase of my current 2018 Ram 2500 at 120% of the current market value; or -Manufacturer Replacement – A comparable vehicle with no unremedied recalls, free of the defect, and without additional cost Legal Assertion: I am submitting this complaint in good faith under 49 U.S.C. §30166 and related federal safety defect statutes.

In early December my 2018 ram 2500 was giving error messages to service anti-lock braked and service Electronic brake system. On December 19, 2018 I took the Ram to the dealer and the cause was the HCU-ICU stating internal electrical failure. They installed a new (Control unit HCU - brake- anti-lock module. It was fine until October 2024 when the same errors (service Anti- lock brakes / Service electronic brake system.) I received a RE-Call notice about the same module (HCU) having issues in November of 2024. I have called the dealership and they have not received a remedy (parts) to fix the issue. The error messages keep coming on Saying service anti-lock brakes- service electronic brake system. Its July 31, 2025 and Still no remedy from the dealership. I signed up on the RAM / Chrysler / Mopar website to be notified when a remedy is parts are ready however I believe it's been too long to wait and appears Im not the only consumer waiting on one. is there any way to remedy quicker I pull a travel trailer and don't want any failures although the dealer said the truck is ok to drive,

I have repeatedly asked the manufacturer and the dealership for a resolution to the antilock brake system failure on this vehicle. This issue has been on going for months and I have no resolution. This is Ram case management # 93024671. My last correspondence is as follows: Dear Stellantis Case Management Team, I am writing to express my profound dissatisfaction and serious safety concerns regarding my vehicle, 2018 RAM 2500. This letter follows a delayed response to my initial inquiry about the safety of my vehicle and family, which I find unacceptable. Firstly, I request an immediate and definitive anticipated release date for the crucial part that is pending. The continued uncertainty around this essential component is directly impacting my peace of mind and the perceived safety of my vehicle, my family and the general public. Secondly, I demand a thorough explanation regarding the active fault code on a manufacturer safety device within my vehicle, which your company has inexplicably deemed "normal" and stated the truck is "able to be driven." This assessment is illogical and deeply concerning. If a safety device, such as the anti-lock braking system (ABS) or a similar critical component, registers a fault code, its integrity and intended function are compromised. My fundamental question remains unanswered: If a safety system with a fault code is considered "normal" and safe, then why are such sophisticated safety features like anti-lock brakes installed in the first place? If their compromised state is acceptable, why not simply remove the entire system? This reasoning fundamentally contradicts the purpose of vehicle safety design and creates an unacceptable risk for myself and my family. I gave them 7 business days to respond- there has been no movement.

Experiencing persistent ABS and Anti skid lights flashing on dash board along with persistent dinging, which has become very annoying. Took the vehicle to my nearest Ram dealership and they ran a diagnostic on it and told me that it was a faulty ABS/HCU causing the problem, but that there were no parts available to repair it. They said they would call and schedule an appointment to have it repaired as soon as the parts become available. I don’t know if I can wait much longer, as the constant dinging is very upsetting to my wife, who normally drives the truck.

Hello, I received my recall notice cb4 hcu component and in my notice it said my truck has already been fixed. My truck has not been fixed and I called fca 10 or 12 times about the issue and I have received 10 or 12 different answers and they still haven't fixed my notice on the recall. What else can I do to get the issue fixed. Thank you [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

First, I was not involved in an incident or accident with my vehicle. My concern is for my safety in the future while driving this vehicle. My RAM 2500 Power Wagon has a safety recall C4B/NHTSA 24V-896 for the brake system but there are no parts available to fix it. I currently have an ABS caution light with a "Service Electronic Braking System" and "Service Automatic Braking System" that constantly flashes and dings at random. I took my vehicle in to my local dealership and they told me there are no parts available and they were unable to fix the ongoing problem. I asked if my vehicle was safe to drive and they told me they cannot legally tell me if it is safe or not. There is no way forward to fix my vehicle and I haven't received any information other than "we are waiting on parts". With this being a safety issue, I would expect a loaner vehicle of a similar make and model. I do not feel it is safe to continue to drive my truck with these warning lights associated with an active safety recall. I am looking for advice or some help with this issue.

HCU unit intermittently come On and off. Has the potential for loss of traction control and braking.

The Anti-Lock Braking System (ABS) Traction Control warning light and warning bell comes on after hitting bump in road or just randomly. Anti-lock brakes no longer work and it is a safety hazard. this issue back at about 78,000 miles. This is an ongoing safety problem with Ram 2500's and there is no recall by the manufacturer for a known defective part.

The service abs and service electrical brake system flashes on and off, dings. Occurs at all speeds, in town driving seems to make it ding worse on and off on and off Some days it doesn’t hardly do it, some days it is non stop. This prohibits the use of cruise control also, with a faulty braking alert the cruise aUto disengages From looking at dodge forums this is a very common issue in 2018 2500 ram trucks. A friend of mine who has the same truck is currently also having the same issue. No one but dodge can read the code or make a repair or even get the parts. They are covering up the issue I believe. You can find tons of people complaining of this issue and dodge needs to issues a recall. [XXX] [XXX] 2018 Ram 2500 [XXX] 2018 Ram 2500 Both having same issue conway ar I’ve talked to a local shop and they said they have seen several with it but their scan tool won’t tell them anything the software is blocked by ram. I have found enough info to know what parts are required to repair it but you can’t get the mopar parts anywhere but dealer. On average this is costing people 1600-2000 for the repair of the abs module [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The ABS service light keeps coming on and beeping. It will go off after a little while but then returns intermittantly while driving. Apparently this is a known problem and should be a recall. Many owners are wasting thousands of dollars for repairs that should be covered by a recall.

Had to replace HCU/ABS module July 2021 due to failure and abs/traction control lights illuminated fault code C0020. Now November 2024 i am having the same problem with the HCU/ABS module abs/traction control lights intermittently illuminated with fault code C0020. In process of locating new module and scheduling for repair.

Abs service abs lights come on with traction lights keep flashing and ringing.

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE continues to come up in my vehicle each time a bump in the road is hit. I am very concerned that this will cause intermittent or permanent loss of braking performance while driving and potentially endangering myself and other motorists. There are numerous complaints about this same issue on the internet with these model year trucks and FCA should be doing something about this inherent risk.

Abs and traction control light goes on and off constantly. When the lights come on, traction control doesn't work, brakes don't worry as they should, and 4x4 doesn't work. Almost caused me to have a wreck in the rain with no traction control.

Hello, I have an Anti Lock Brakes electrical motor failure on my vehicle. The motor failed once at 20000 miles and failed again after a warranty replacement at 60000 miles. The part is on national back order for 2 years now and keeps the ABS from being fully engaged. It also disables cruise control and constantly dings. Two Dodge dealerships have confirmed the issue. The code is C0020-01

The ABS Light along with the EBS light were popping up on the dash every 2-3 seconds. My cruise control quit working. The truck is steadily dinging. I am sure the ABS will not function when this light is on. I am worried the truck will not handle well on wet roads. I have a [XXX] and a [XXX] . Please help me resolve this issue.

ABS needs service. Was quoted 2k from Dodge for repairs. As well as electric brake system not working Chrysler told me it is safe to tow my 10000 lbs rv with the errors and no ABS.

Service electronic braking system Notification and ding won’t stop going off. Truck has less than 50k and through my research this is a common issue with this truck. I don’t want to drive it anymore fit safety reasons. Bought the truck 2 months ago and have had an issue since I purchased it

The component or system that is failing or malfunction is the ABS Hydraulic Control Unit (HCU) and ABS module. The malfunction is turning off my ABS and TCS system, making the vehicle unsafe to drive. Also the ABS and TCS dash lights are constantly dinging and going off and on distracting me while I'm driving. This issue is well know with the dealer. Here is a TBS from 2020: RAM TSB S2005000004 The vehicle has been inspected and and the ABS module was already replaced, but didn't fix the issue. This has been happening since I bought the truck.
