2017 RAM 2500 Complaints

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

The contact owns a 2017 Ram 2500. The contact stated the ABS warning light illuminated intermittently. The vehicle was taken to the dealer where the ABS sensor was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where the mechanic replaced the ABS sensor a second time; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 10,000. The contact stated that the failure has occurred three times now. The part necessary for repairs in currently on backorder.

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.

The vehicle was purchased new Oct. 2017. On or about 1 Oct 2020 the vehicle had 19,100 miles. The vehicle displayed a constant "ABS Fault" / "Traction Control Fault". This was reported to my local dealer in Panama City, FL. The dealer service dept. worked the current Recalls and the ABS Fault at that time. Service was completed 10/16/2020. The vehicle was still under the basic 36M/36K mile warranty. The dealer reported the replaced part as MOPAR # 68143491AA, brake controller module. The vehicle is not in daily service, so the mileage is low for the age of the vehicle. On or about 1 June 2022, the vehicle had 22,250 miles when the ABS Fault resurfaced. At first it was intermittent, but later the ABS Fault / Traction Control Fault is constantly displayed. The brakes feel and appear to work normal, but I feel they would not work as intended during a hard braking or a skid or on wet pavement. I read dozens of owner blogs, Cummins forums, Ram owners forums, U-Tube, etc. It seems a large number of similar trucks are reported by their owners to have this problem. many owners like me have reported having this problem fixed by the dealer only to have it soon reappear. Many owners that have had this problem repaired also indicated the same part or part number and/or cite the trouble as brake hydraulic controller or a controller module.

Hydraulic Control Unit failure on Ram 2500. This causes antilock brakes to stop working as well as traction control.

The steering components are causing it to be difficult keeping the vehicle in the driving lane; the vehicle wanders from side to side. Two seperate Dealers cannot locate the problem.
