The ABS and Traction control lamp keep flashing on and off intermittently. When those warning lights are not lit up, I can use the truck normally. However when they do light up cruise control no longer functions. I have not tested if ABS or Traction Control is not functioning, but I am not going to take a chance. This endangered my family, and surrounding drivers as I was towing our trailer on the freeway and had set the cruise control. In the middle of the drive, the warning lights came on, and the cruise control turned off by itself. At the time we were climbing up a grade, so the truck slowed down rapidly. The Semi-Truck behind almost crashed into me as I tried to determine if I had an engine failure, and deciding if I had to pull over. They honked at me repeatedly. I determined that it was not an engine failure and I could increase speed. By then the truck was below 30 mph. I may have caused more catastrophic issues behind me but, I could not see past the 5th truck behind me. My wife was screaming at me to pull over, and was upset that the vehicle was not working. It works, but the brakes are not dependable for ABS, and cruise control is not dependable. I drove the vehicle several times since and the issue keeps occurring. I have not taken it to a dealership, and do not drive the vehicle anymore at this point. The vehicle has not been inspected as that would require driving it to be inspected. The ABS and Traction Control warning lamps started to illuminate around November of 2022. That was the only indication that something was wrong. I was going to take it to the dealership but it is out of warranty. It drives fine otherwise when the lamp is lit, and it does goes on and off with a dinging sound, but I could not tell that anything was not working. It was not until the incident with the cruise control that I realized it impacted the ability for the cruise control, and that it would turn it off when I am using it. It is completely random.

The ABS and Traction Control lights flash and ding on/off intermittently. Sometimes the lights on the dashboard come on as soon as I leave the driveway and sometimes it takes several miles. But once they flash on and ding on the dashboard, the lights flash on and off intermittently for seemingly no reason at all. I am not sure if this is due to an electrical issue, a hydraulic control unit issue, or something else, but something is not right, making the lights and dashboard flash/ding a lot.

ABS Service Light and warning bell keep coming on. I've had this fixed twice and appears looking at forums that investigation is under way as part is failing on most all 2017-18 Ram 2500 trucks. Please make Dodge to replace under recall.

Issue with ABS and HCU. Known issue with Ram trucks but no recall for 2018. "Service Electronic Brake System" warning comes on and off constantly.

- Arlington, TN, USA

The ABS-HCU is defective causing a loss of the safety aspects of it purposes, Constant warning alarm and flashing screen.The parts to repair are not available. My dealer is not optimistic of the part replacement correcting the problem, it might be the Electronic Braking module, got an additional fee. The dealer would not say it was safe to operate but advised against towing I stated that was the purpose of the truck.

While driving with cruise control activated the Service ABS light came on and made an audible ding and the cruise control deactivated resulting in a loss of speed traveling along an interstate highway. This has happened several times, and no time frame to get fixed.

ABS warning light comes on and off again. Each time it comes on, the cruise control turns off. This continues to happen -- going on and off. This is unsafe as the trucks cruise control stops functioning without warning.

This truck has just over 40k miles and the hydraulic control unit and the anti-lock brake system module has failed 3 times. The first failure was at 28k miles, the second failure was at 36k miles, and the third failure was at 40k miles. When the systems fail ABS, Traction Control, and Cruise Control are all disabled. The problem is easily reproducible by the dealer, and at the 3 RAM dealerships I have been to, the service managers all say this is a problem that plagues all 2017-2018 RAM 2500 and 2018-2019 RAM 3500 trucks. If you at any of the RAM forums or Facebook groups you will see this is a very common failure that leaves the owner without ABS or Traction Control, which is very dangerous when using the truck for its intended purpose (hauling trailers). This problem is so common that the part is commonly on backorder for 3-6 months. When I went to the dealer after my latest failure in Nov 2023, I was told the part would not be available until sometime in the summer of 2024. The the failure occurs the ABS and Traction Control Light come on, and you get a message that says "Service Electronic Braking System". RAM really needs to redesign the part(s) and issue a recall for this. The contact stated that the vehicle has yet to be repaired.

Intermittent -??service brake system-?? comes on. Spoke to dealership and said they do not have the part to fix the brake system. It is on back order being -??re-engineered-?? and have no indication when it will become available.

- Bossier City, LA, USA

The truck randomly started flashing service electrical anti skid braking system. It will go on and off randomly and other times stay on all the time. It will not allow cruise control to work and I-??m guess my ABS will not work either if I need it. I bought the truck with 132K miles on it and the light starting coming on at 134K miles. I don-??t want to possibly injury others or myself is the ABS does not work. I took it to the dealership and the light went out and they couldn-??t see any codes. The light is back and almost always on. Going to take it back to the dealership. To see if they know what is wrong since this is a known issue with most Ram trucks.

Traction control and abs warning lights flash on and off intermittently also cruise control not working when this happens. It is sporadic

- Young Harris , GA, USA

The truck intermittently shows an alarm for failure of the abs braking system. This suddenly shuts off the cruse control and disables the abs. The loss of cruse control caused the truck to suddenly drop in speed in a highway traffic situation, which nearly caused a car behind me to hit me. The loss of abs leaves the truck vulnerable to brake related accidents in slippery or wet weather. I contacted a dealer for the replacement parts and they told me they would not be available until a new generation of abs module and hydraulic control unit were available. I believe the NHTSA should demand a recall for this extensive and dangerous issue.

On 15 Nov 2023, my ABS and Traction Control warning lights illuminated. I took my 2018 RAM 2500 Tradesman Diesel truck to my servicing dealership (Fayetteville Dodge Ram, Fayetteville, NC) that afternoon and was told I needed to replace the ABS Module (Mopar OEM 68347098AB) and Hydraulic Control Unit HCU (Mopar OEM 68143491AB). The dealership's parts department told me there was a backorder of about 4,000 of these parts nationwide. I attempted to obtain these parts through Mopar Parts Overstock and was told the same thing. After many internet searches, I find that this issue is wide-spread and potentially dangerous. I am now driving my truck with this brake defect, although my dealership assures me the braking system is safe to operate. Why is there not a recall on this wide-spread issue?

Warning Lights for "Service Electronic Braking System" and "Service Antilock Brake System" come on and off indicating repairs to module necssary; however, Ram/Dodge can't schedule repairs for over a year in most locations. This is an ongoing problem and it appears to be affecting thousands of owners of Ram pickups. The code is C0020-001. The ABS/Traction control light comes on - a message to service the Anti-Lock braking system comes on - and the cruise control does not work. This happens intermittently sometimes several times in a minute, sometimes it's several times a day and sometimes it will stop for 2 or 3 days without the warning lights coming on at all. It's very frustrating and unnerving as the cruise control just drops out while you're driving which is not safe. The ABS also does not function with this issue. This issue needs to be addressed. Additionally Ram/Dodge dealers indicate this is a well known problem and that there are parts shortages for this repair due to the amount of Ram pickups having this issue, the parts are in short supply with everyone needing to make this repair. Please require Ram issue a recall. This is not safe.

Twice the ABS hydraulic control unit has become faulty and no unavailability of parts. The -??issued warning-?? from Chrysler corp is be weary as the truck no longer has cruise control, 4 wheel drive, and a warning light and audible alarm that comes and goes to on/off every two to three seconds causing an immense amount of mental irritation while driving. This vehicle has been looked at twice by dealerships have diagnosed and also charged me every time to hook up to their diagnoses (around 200$). I have called RAM cares who is nothing more the a shell of the company to appear as though they care but of are little to no help. So recap, I have a ($60,000) truck that is the equivalent of a base model s10 ($15,000)(basic model truck) because one part has made it impossible to use the truck in its fully designed capacity. No four wheel drive, no cruise control, and a dinging and flashing light that happens every 2 seconds and a message that say service electronic braking system. I would upload a video but you can literally google -??HCU ram 2500 problem-?? and a slew of videos will pop up. Maybe someone at either this organization or Chrysler will actually care and start holding people responsible for this problem and issuing a [XXX] fix.

My ABS and Traction Control lights keep coming on and cruise control will not work when the lights are on. This has been occurring for the past few years. The lights are on most of the time and I-??m afraid my abs breaks will not work properly especially when i-??m pulling a trailer. This is an ongoing problem with 2018 Ram 2500s. Ram needs to remedy this problem.

2018 Ram with brake module problems. In September 2022, warning lights came on stating that the antilock brake system and electronic brake system were failing. At this time the problem was known to the dealership and parts were found and replaced under my extended service contract. Parts replaced were the: Module, Anti-Lock Brake(68347098AB) and the Control, Anti-Lock Brake System(98143491AA). Replacement was done at Payne Chrysler Dodge Jeep Ram Edinburg with Mopar parts. Replacement was done September 15th, 2022 service repair order #565792. Mileage at the time of repair was 38,538. On November 5th, 2023 the exact same symptoms appeared. On November 28th, the truck was diagnosed at Payne CPDJR with needing the exact same parts replaced. Mileage at this point was 41,998. Clearly, this is a serious problem if the exact same parts need to be replaced after less than 4,000 miles. This is obviously a dangerous and ongoing issue that needs to be addressed. I have been advised not to take the truck outside the local area until repairs are effected. I have a truck because we live on the road full time and use it to tow our 5th wheel(total weight is 9,800 pounds fully loaded which is easily within the trucks towing capability). As of today, December 8, 2023 I was advised that the parts were at least 2 weeks out. I contacted Chrysler customer care and opened a complaint. When the modules show failure, the cruise control is inoperative and it is advised to take the truck into a dealership immediately. Someone needs to make FCA step up and take responsibility for this clear disregard for customer safety, by ensuring that these parts are reliable and available if needed. Having to replace the exact same parts twice shows a clear disregard for quality control and vehicle safety especially when these parts are going to take a month for the dealership to receive.
