ABS Brake system failure. Multiple reports of -??17--??18 yr models with exact problems.

- San Antonio, TX, USA

My truck has an intermittent ABS light along with a traction control light and a message displaying Service antilock brake system and service electronic brake system. these lights also sometimes stay on until the next ignition cycle or even several ignition cycles. it also disables the cruise control as well causing an extreme loss of speed on the highway especially when traveling up steep grades. there were no issues leading to the cause of the lights to come on to my knowledge and i have not visited any sort of dealership or service center regarding this issue nor do i have the time or funds to correct this issue at this time.

The Anti-lock Braking System (ABS) and the Hydraulic Control Unit (HCU) issue is present on my vehicle. The problem is intermittent and occurrences cannot be predicted, duration fault varies, sometimes repeatedly cycling fault/no fault/fault etc. When the fault occurs cruise control is either canceled (if active) or not available. Occurs at varios speeds. Please refer to NHTSA's open investigation (NHTSA Action Number: PE22012).

ABS/Traction Control warning alarm constantly going off, and affecting cruise control.

- Brighton, TN, USA

The ABS module is defective on my truck which controls the antilock brakes, Anti slip function, and the cruise control. Dealer ship has diagnosed problem and ordered parts but the parts have been on back order for quite sometime with no ETA from RAM when parts will be available. My dealer ship says they currently are wating on 25 parts for different vehicles with same problem.

- Paris, TX, USA

I'm just reporting the failure of my HRU as many RAM owners have experienced. The dealer ship replaced the part with the new model. When this fails it happened at highway speeds disabling the cruise control while towing a trailer. Becuase of busy traffic and under heavy weight when the truck fell on its face. I was almost rear-ended due to the sudden loss of speed. Very dangerous when towing.

The abs light blinks and sounder beeps on and off intermittently while driving and the cruise control does not stay functioning when this occurs.

Originally I started feeling like my brakes weren't stopping as well as they had been. The pedal seemed to feel soft and have further travel than normal. I recently had my brakes inspected by a certified mechanic, so I was confident it wasn't the actual brake pads, rotors, or calipers. After a day of this I started getting intermittent ABS system and traction control lights. About a day or two later the lights became more frequent until they eventually stayed on. During that time I was out of town while pulling my fifth wheel camper, so I wasn't in a good position to get the truck to a mechanic. Needless to say I felt my situation was becoming unsafe. Once I returned home I got the truck in to my mechanic and his troubleshooting led to a faulty ABS module and Hydraulic Control Unit. This was a very expensive repair. Once I was told what the diagnosis was I started to research this issue online. This is when I discovered that others were having this same issue and that the NHTSA had already opened up an investigation into this.

The "Check Antilock Brake" message appears on the dashboard. The vehicle has been inspected by a mechanic who confirmed that it is either the supplementary brake fluid pump, or the brake pump control unit. Because of the intermittent nature of the problem, the manufacturer requires replacement of both expensive parts, as they do not know the exact problem. Because of the issue, the following vehicle features do not function: * anti-lock brake system * electronic stability control / traction control * cruise control * the holding of the rear brake on a hill until the operator accelerates (important in a standard transmission truck used for towing)

Abs light and traction control light will flash and beep intermittently when driving have researched a lot of people have the same issue newer models have been recalled for the same problem.

- Christiansburg , VA, USA

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.

- Puyallup, WA, USA

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 electronic braking system failure.

- Ballwin, MO, 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

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 ($15,000)(basic model truck) because one part has made it impossible to use the truck in its fully designed capacity. No four wheel drive, no cruise control, and a dinging and flashing light that happens every 2 seconds and a message that say service electronic braking system. I would upload a video but you can literally google -??HCU ram 2500 problem-?? and a slew of videos will pop up. Maybe someone at either this organization or Chrysler will actually care and start holding people responsible for this problem and issuing a F%$#ing fix.

- Hollywood, FL, USA

ABS light and traction control warning on dash. Truck has been in shop previously for the same issue. This causes my truck to lose cruise control at highway speeds and to not have traction control capabilities when driving on wet roads. I will be taking the truck back in to the shop this week as this is occurring at all times and does not stop dinging.
