Started having abs and traction control issues in early October of 2022. Have had two cases of compleat brake lock up. Took to ram deal for repairs and it was diagnosed as the abs hydraulic unit. When road conditions are icey and slick will have issues with the brakes locking up.

"Service ABS, " "Service Electronic Breaking System, " and "Traction Control" caution lights illuminate on vehicle during driving. Started with intermittent illumination. Took vehicle to dealer and was told that ABS pump failed, but no parts are available to repair. Service advisor said it was ok to drive, that the brakes will function without ABS system. Brake performance is diminished. There is no pumping sensation when I apply brakes hard.

When driving, the Service Anti-Lock Brake System (ABS) light would intermittently cut on and off and would disable the ABS system and Traction Control system. This would happen at any speed. I scheduled an appointment at Pearson Chrysler Dodge Jeep in Richmond, Virginia for 11/22/2022. I was told the ABS Control Module was defective and the part had to be ordered. The dealership advised that this equipment has malfunctioned in many 2017 Ram 2500 trucks and that the part was on back order until late January 2023. They also advised me that if I drove the truck when the light was on I would NOT have anti-lock brakes or traction control. I have called multiple times to inquire about the status of my part order to get the safety issue fixed. I was told in January that the part still wasn-??t in and that the timeframe was pushed out to March. I called again today (3/17/2023) and was told the part now was in the process of switching suppliers and that they did not know if or when my part will be available. This is a huge safety issue. My truck has been mostly parked since before Thanksgiving and it-??s now almost April. RAM as a manufacturer is creating a large safety issue for anyone with this same issue. I have not been able to get my truck serviced properly with OEM parts due to their negligence. This is a warranty claim and my contract will expire in 2 months and I am not sure if this will be covered once or if the part ever arrives. Please assist in getting this issue resolved. I do a lot of towing and depend on this truck to be safe for me and other drivers and RAM is preventing this from happening. My truck is still mostly parked and cannot be trusted on long trips. My truck is also due for state inspection in June and this warning light will cause my truck to be rejected and then I will not be able to drive it at all.

I have dash lights going on and off for the ABS and traction control. This is very intermitted. On two occasions I have experienced times where I had to slam on the brakes to avoid an accident. Both times the ABS failed to work causing me to come to near collision with another vehicle. One of the times this caused me to go off into a ditch. This was with slick roads and snow covered in areas. Have also had several times the truck would steer out of control with no traction aid. I am constantly losing speed control using cruise control. It will work for a bit and then turn off when the ABS and traction control lights come on.

Second failure of ABS system in 2 years. Error code c0020-1 for failed ABS HCU part number 68143491AB. Replacement parts are currently unavailable from manufacture and has been in the status for nearly 6 months. Service center is unable to restore functionality of brake systems and vehicle has been un-driveable due to ABS safety concerns since October 2022. As stated this is my second failure with same part, first failure was in Sept 2020.

ABS light and alarm come on and goes off at random intervals. This issue was repaired before on 03/04/2020 and now the issue is reoccurring when rain or hight humidity. The original ABS code on the system was C0020-01 (ABS pump motor control - general failure). The HCU part #68143491AA was replaced and ABS module the issue corrected. My concern is that the ABS is disabled on the vehicle once the condition occurs and could result in loss of control during a hard or panic stop. I pull a 7,000 lb trailer and am concerned that if a hard stop occurs the truck could start sliding and cause the truck and the traile to lose control.

ABS light and alarm come on and goes off at random intervals. This issue was repaired before on 10/06/2020 and now the issue is reoccurring. The original ABS code on the system was C0020-01 (ABS pump motor control - general failure). The HCU part #68143491AA was replaced and the issue corrected. My concern is that the ABS is disabled on the vehicle once the condition occurs and could result in loss of control during a hard or panic stop. I pull a 12,000 lb camper and am concerned that if a hard stop occurs the truck could start sliding and cause the truck and the camper to lose control.

Faulty break module. Dash reads service antilock break system, ABS light on in dash, traction control light on as well. Cruise control will not work because of this issue. Intermittent occurrences at first, now constant after 3 years. It has been taken to multiple dealerships, while under warranty with these exact problems. No results! An independent service center diagnosed this issue and has ordered the part. Have been waiting two months now still nothing.

- Haubstadt , IN, USA

The service abs and anti lock brake light comes on and off. I have talked with 3 different dealers and they all told me the abs module is probably bad. The part is on backorder for the last year, so I can-??t get it fixed.

ABS / Traction Control lights began intermittently turning on. After roughly 5k miles, the lights are on all the time. The truck is throwing code C0020-01. From looking around online, this is certainly not a unique situation. The fact that there is an updated HCU (P/N 68143491AB) to be released later this year, shows that this is a known issue.

ABS and traction control systems are malfunctioning. Dodge dealer states that the abs module and hcu need to be replaced which both are on back order. Roughly $1500 worth of parts and labor are required to fix issue at my cost. Truck has 80,000 miles currently and problem started about 1000 miles/month ago. Both abs and traction control lights flash on/off constantly.

Truck continuously warns and chimes to "Service Electronic Brake System." Truck no longer has working ABS. https://static.nhtsa.gov/odi/inv/2022/INOA-PE22012-9925.PDF

ABS module and hydraulic control units replaced in 2019, after driving the truck less than 20k miles the exact same issues have returned. Truck is out of warranty now, no cruise control, ABS, or traction control. Very common issue amongst 2017-2018 Rams. Second issue happened recently when temps dropped below freezing. DEF system fault - DEF injector checked for crystallization. No crystals - truck will go into limp mode rendering it useless due to an inferior component manufacture is aware of and have addressed on new models but have not afforded older models a solution.

Around the 1st of October I started to get the Service Electronic Braking System and ABS warning lights on my Ram 2500 so I took it into Rairdon-??s in Bellingham, WA on November 8, 2022. (Note- it took me 4 weeks to get an appointment to take it in) I was informed that the HYDRAULIC CONTROL UNIT (HCU) is faulty and to replace it first and if the fault code comes back then replace the ABS module. Never heard back on the HCU part ETA so I called back to the dealership on November 15, 2022 and was told the HCU will now be in January 18, 2023. Once again when I contacted the dealership on January 8, 2023 and I was told the HCU is now pushed out to March 15, 2023. So I have to wait 4 months (if it shows up to the dealership in March) to get a Mopar part to fix my vehicle?

My dash will randomly start flashing the messages "service electronic braking system" and "service antilock brake system". Sometimes this happens as soon as I start the vehicle, other times it happens while driving down the road. Sometimes it seems as if a bump in the road will trigger the messages, others are random. When the messages are there, the traction control feature does not work. I do not know if the abs system will work or not as I have been lucky enough to not have to test that. Also, while the messages are present, the cruise control function will not work.

2017 Ram 2500. ODO 77,000 miles While driving at any speed, warning lights and audible tones intermittently come on. Display reads "Service Electronic Braking System" and "Service ABS". ABS and Traction Control lights also illuminate on the dash. Sometimes the warnings will come on and off so fast that the truck is constantly chiming which is very distracting. Speed doesn't appear to be a factor. Sometimes the warning lights stay illuminated. Sometimes they go away. Sometimes they flash on a off rapidly. Truck has not been taken to the dealership yet but an appointment has been made and the dealer said it is most likely the ABS module and Hydraulic Control Unit that needs to be replaced. This sounds like a known issue. Safety issues I am concerned about are: Loss of ABS and traction control. Trailer braking system issues while towing (horse trailer). Distractions from audible alarm constantly chiming, loss of braking power.

Starting roughly a year from the date of this report, the vehicle would randomly issue a warning "Service Electronic Braking System" and turn on the Traction Control and ABS warning indicators; it would also disable Cruise Control. These errors would appear sporadically and persists for a few seconds to a few minutes. The dealer was unable to diagnose as the error was not actively triggered at the dealership. Over time, the error happened more often and persisted for longer time periods (minutes, hours, then days) but would eventually (and randomly) reset. It became clear that it was oftent triggered by a sharp jolt or a tight turn. Recently the error stayed on permanently and the dealer was able to retrieve an error code which led them to suspect a faulty connector. It took 6 weeks to get the connector and when the dealer attempted to install it they came to the conclusion that both the wiring harness and the connector are OK. They were able to retrieve additional error codes that pointed at the HCU (Hydraulic Control Unit) of the ABS system needing replacement. No HCU units are currently available. I have conducted extensive online research concerning this issue and the four symptoms: 1. "Service Electronic Braking System" message 2. Traction control indicated lit and traction control disabled 3. ABS indicator lit and ABS disabled 4. Cruise Control disabled and found that there are a large number of reports for RAM 1500 and 2500 models with mileage as low as 12,000 miles. This appears to be a wide spread failure of the HCU component that points at a flawed part that causes significant safety issues as it randomly disables both traction control and ABS functionality. RAM simply burdens the consumer with the cost of having to replace the HCU, sometimes multiple times as new units tend to fail again.
