Abs problems due to HCU

- Boerne, TX, USA

Intermittent ABS and traction control lights. Service lights come on and go off when braking or driving over bumps. Code C0020 - ABS Pump Motor Control General Electric Failure. Issue is so random I haven-??t taken the truck to a service center.

- Virginia Beach, VA, USA

Continued failure of hydraulic control unit (HCU) and Anti-lock brake system (ABS) module causing fluctuations in brakes at times (have to press harder on brakes) and lights go on and off, sometimes staying on for lengthy periods (usually on highway) or while driving and disables the cruise control. Second time in just under 3 years (fixed in Nov 2020 and reported to dealer Sept 2023), same issue on parts both time, fix identified as faulty HCU and ABS module as dealer identified issue and placed order for parts (5 month backorder to Feb 2024 as apparently very common issue with these trucks). The issue is both the change in brake sensitivity due to this part failure and the sudden cancellation of cruise control, the braking impacts the braking performance and cruise control drop out causing sudden drop in speed on highways.

Abs/traction control errors Alarm keeps coming in and going off This is the 3rd time this truck has had the same issue

Braking failed on vehicle, manufacturer refuses to provide repairs parts nationwide on all Ram 1500,2500,3500 trucks

- Inverness, FL, USA

Whenever it rains or is high humidity, my dashboard lights up and repeatedly chimes with ABS lights and Electronic Braking System error. The error repeats itself on and off again every few seconds. It is a dangerous distraction of error messages. Since it is raining, all traction control and ABS systems deactivate themselves with this error. I spun out this morning due to the error. It is absolutely dangerous. This is the EXACT error that occurred on my previous Ram. This is a dangerous faulty hydraulic control unit (and ABS system). Upon a little research, I found tens of thousands of posts of owners being stranded or driving without ABS / traction control due to this malfunction. This is deadly and needs to be recalled. RAM is aware of this issue but has not issued a recall. It is raining today, and my RAM will not have traction control or ABS. This is unacceptable. This is affecting tens of thousands of owners. With upwards of $1,600 for a repair. Yet, the part can create a fault AGAIN within weeks or months. DANGEROUS.

Hydralic control unit is bad causing on dash safety alert for service electronic brake system alert and anti lock brake system alert. When towing will not have brakes to assist in stopping tow vehicle. The alarm constantly going off distract your attention from the road. Upon going to the dealer for repairs I was told they are on national back order and may not be available until after the 1st of the year. It apparently a widespread issue with all 2017 and 2018 Ram 2500s. I am unable to tow my 38' 5th wheel camper for fear I will lose my brakes on the tow vehicle putting myself and others at risk. The anti lock brakes not functioning properly could result in losing control of the vehicle when road conditions are wet or slippery. This loss of traction put me and other motorist at risk. Ram know there is a problem with the HCU. My understanding is they have had to completely re-engineer the part and as such has created an availability problem for anyone owning these vehicles. There are several blogs and forums online describing this as well as a class action suit initiated by the state of California. Would appreciate you looking into this matter and getting Ram to do the right thing. Thank You

The ABS and traction control indicator lights come on and off intermittently. This is a huge safety concern has the ABS and traction control may malfunction. This issue has been brought to the dealer and they replaced parts less than two years ago. It has reoccurred less than two years later.

2018 Ram Sept 23, 2020 at 15,000 miles ABS light flashed on. Code said pump electrical failure. Dealer replace under warranty. Oct 12, 2023 at 50,900 miles, service ABS notice flashes on screen. Dealer confirmed ABS failure but said parts were on indefinite back order. Said last one took over a year to get parts in.

Intermittent warnings of ABS system needing maintenance while driving. No known cause or correlation to type of road/weather conditions. Intermittent ABS failure affects ability to use cruise control. This started when the truck was at 52k miles. This has been happening for over a year now and we have been told that there is an indefinite timeframe for repair due to massive back orders.

ABS service light coming on, and service electronic brake system keeps coming on. Recall on 2019-2022 RAMS for same issue. Told to report issue here.

The ABS and traction control systems on our 2018 2500 RAM truck are failing randomly, and the warning lights are coming on. The cruise control system is also randomly failing. Therefore, as we drive the vehicle and using cruise control the vehicle will randomly turn off the system causing safety concerns. The braking system and traction safety systems are not working properly and safely. The cruise control issues have been occurring for about 2 to 3 months. Over the last 1 to 1.5 months the ABS and traction control systems have started randomly failing and turning on the warnings lights and bell. We took the vehicle in for service today at the RAM dealer and was informed that the parts are backordered and unknown when any parts would be available. The dealer confirmed the systems are not functioning properly and provided written estimates and summaries of their findings. The dealer advises to replace the HCU and retest the system. The dealer advised to replace the steering wheel wiring and cruise control switch. The vehicle mileage at the time of the dealer evaluations was 23,052 miles.

Anti Lock brake system and service electronic brake system message keeps going on & off every 30 seconds & will shut down cruise control if it is engaged. Happened in 10/11/2021 & now 10/8/ 2023.

My truck has the same issue as many thousands of other RAM owners. The forums are full of people with the same issue. It clearly is a faulty part/design or similar. My "check ABS/ Traction Control- Brake light" turns on and off intermediately all the time. It is an issue many have had and had fixed for between $800-1,000.00. For your reference here are some links to forums showing this issue in fact a OEM problem. Apparently there are class action law suits going on in Texas and California over this matter. [XXX] [XXX] [XXX] There are many more. RAM should have to furnish a recall and fix this issue at no cost. Parts are not available until February of 2024. This is a safety concern!! This issue will not allow the use of cruise control or remote start. Winter is coming and im not sure the ABS works as long as the light is on. RAM needs to supply parts faster than Feb 2024 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Intermittent ABS light and Service Electronic Braking System lights coming on and off. Appears from previous reports this is a known issue that has been going on for years now with this vehicle and should be fixed. I purchased a new hydraulic and electronic module from dealer at around 35000 miles and replaced. Issue was fixed or so I thought, at around 70000 miles lights are intermittently on and off again. No known issue was contacting ram direct, dealer I bought vehicle from stated the electronic module is backordered and has already been replaced with another part number, I believe it was a faulty replacement from the get go. Hydraulic module was said to be under engineered testing again per the dealer. Extremely frustrating from the customer end, no cruise, no abs braking capabilities. No known deaths to this point linked to this specific issue to my knowledge but I wonder if Ram will move a little faster on the fix or recall once they have something fatal on their backs for this.

- Needville , TX, USA

the abs module and the hydraulic pump have a issue that turns on the abs and light and turns off the cruise control and reverts to non abs braking due to faulty module and pump assembly that was changed already and now the wont cover this under any warrenty known faulty part

- Bradenton, FL, USA

ABS/Trac lights ding constantly with the dash displaying "service electronic stability" or something along those lines. ABS system becomes inoperable as well as kicking your cruise control off. Very unsafe and parts are not available for repair as well as Ram not taking recall action up to this point.

ABS module failure, brakes can potentially lock up causing you to slide. Preoblem has been verified, but has not need inspected by manufacturer (on my vehicle). And there were no symptoms, light came on as soon as it failed
