My ABS module and HCU are acting up. Warning lights on dash keeping going on and off intermittently stating service Anti Lock Brake system and Service Electronic Braking System. Traction Control loss warning light accompanies these lights. I have had the module replaced twice already and still not working. Was told yesterday (Dec 07,2023) by warrant repair facility that there is a new upgraded part available and to file a complaint. These problems started in October of 2023.
2018 Ram 2500 electrical complaints
Page 10 of 17: complaints 251 to 280 of 476, newest first, as owners wrote them.
ABS Module Failure. Truck is available for inspection upon request. The ABS Module Failure directly effects the safety of all occupants and other vehicles on the road if not able to stop as intended to. The problem is confirmed by a dealer. There were no warning lamps until the ABS Module failed and needs to be replaced. This is a standard issue that needs to be recalled.
Abs module is out again. Second time in just over a year since I replaced it last time. This is an ongoing issue and numerous people locally are complaining, so national has to be thousands. Ram is aware of the issue but not fixing.
The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the ABS and Traction Control warning lights illuminated on the instrument panel. The vehicle was taken to the dealer, who diagnosed a failure with the ACU, causing a general electrical failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 50,000.
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.
ABS and traction control lights are on, scanned and got code c002-01. Unsure if system is working. Verified by shop, needs a new hcu but none available to fix, no time line on when parts will be available.
ABS and traction control light are intermittently flashing.
Had brake module replaced under warranty at the dealer and less than 10k miles later it’s doing the exact same thing again. Abs is not working, alarm constantly chiming while driving and abs and electronic brake malfunction lights coming on in the dash. Truck still has less than 48,000 miles on it cause I’m scared for my family’s safety so we just don’t drive it anymore. Is a shame we have a truck we can’t use that we have paid for for this long and still can’t use due to a safety concern that the dealer won’t repair again cause the time limit has expired on the parts warranty.
Service abs system immediately popped up on information screen, also abs and traction control lights all at the same time. This disengages cruise control and removes digital speed reading. Almost got tailgated.
Purchased truck and abs light is on that disables abs and traction control. Which in turn won’t let you use cruise control
This is my 4th HCU/ABS Failure. 3 Priors were replaced/reported in FEB/March to the federal safety agency. ABS / HCU System Failed. My safety was directly impacted. Various warnings and lights on the dash lit up with "Service Electronic Braking System". When the ABS / HCU system has an issue, it deactivates the cruise control, ABS System, traction control, and parking detection system. This can cause a sudden and unexpected deceleration or loss of vehicle control, as the traction control system also shuts off without warning. The dealer is able to verify the issue. I have taken the truck to the dealer, who is reporting a part shortage and multi-month backorder for the part. This is a huge safety issue, and could have killed me and my children. This should become an immediate recall since it directly impacts the safety features of the vehicle as well as the cruise control system, which may suddenly deactivate and cause sudden deceleration. Various warning lamps display. BRAKE, ABS, Traction CONTROL.
ABS light and Traction Control service alert light on dashboard. Second time this has happened. I had this issue prior and had Ram replace both parts that needed to fixed and was not covered by Ram. This/ these are faulty parts and Ram needs a recall. There are thousands of Ram owners that have the same issue and Ram refuses to acknowledge and recall these parts/ issues! Please help us!
"Service Antilock Brake System" & "Service Electronic Braking System" error messages are popping up on the dash on and off while truck is running. Sometimes pop on after starting the vehicle while sitting in drive and other times while driving.
Anti-lock brake / traction control lights come with audible chime. Message reads service anti-lock brakes and service electronic brakes. Problem is intermittent with light coming on for a duration then going out and clearing message center. At times, the warning lights turn on and off rapidly giving multiple audible tones. Activation of light causes deactivation of cruise control. At highway speeds - rapid deceleration occurs. Unknown if the anti-lock brake or traction control will function while light is on. This will be the second time this issue has occurred. First time repair was covered under warranty for same issue. Diagnostic’s performed at authorized Ram dealer (10/27/2023) (Approx. 48500 mile's) indicates issue with Anti-lock brake control and Anti-lock brake module. Remedy - replace defective parts with: 68143491AB Control: Anti-Lock Brake 68347098AB Module: Anti-lock brake Total cost to repair: 1478.25 Dealer states that no factory warranty on this repair. Parts not available until February 21st 2024
While driving the truck my ABS, Traction Control and red brake symbol come on the dash as a warning. The vehicle once this happens no longer can utilize cruise control nor its ABS system during hard braking. This problem began intermittently and has become permanent. Dealerships are unable to get parts for repair.
When I had to use excessive pressure on brakes, I received a DTC and a messaged flashed on my display to service ABS system as well as TCS. I had the DTC read which showed C0020-01 ABS Pump Motor Control General Electrical. It was cleared but when I drove over a speed bump at my kids' school, the same message displays. The message has also displayed during wet weather and minor wheel spin (over white painted crosswalk lines) from a stop. I spoke to a technician from the Chrysler dealership and was informed this has become common and to file a concern here.
Intermittent dash flashing of ABS and "service electronic brakes" messages tied to known HCU/ABS module fault/failure. C002-01 code. Driving over light bumps trigger lights on/off. Dealership told me to ignore lights and code.
I am getting an ABS sensor warning that was previously fixed 3 years ago under warranty but is now resurfacing. It is a constant alarm that prevents the cruise control from engaging.
ABS Control Module causing ABS light to come on, consistent audio warning, and disengages Cruise Control function. Currently being diagnosed by Dodge dealer the ABS Module and Hydraulic Control Units failing internally. Initially it was very seldom, and now is constant.
Vehicle started flashing “Service ABS Braking System” and “Service Electronic Braking System” intermittently. There is no rhyme or reason and no way to make vehicle reproduce this at will.
Trucks and electronic braking and traction control randomly quits working.
Service ABS light comes off and on sporadically. This is a known problem through out the country and needs to be addressed by a recall.
ABS light and traction control light comes on all the time and when lights comes on curse control stop working, by lights coming on all the times don't feel safe to drive truck.
1. ABS/Electric Stability Control service antilock brakes lights flicker on and off. 2. When ABS light is on you could lose control of brakes due to possibility of wheels locking up. 3. Went to the dealer twice to correct the problem and still having the same issue. 4. The vehicle was inspected and worked on by Ram Dealer. 5. No warning lights before failure.
I keep getting warning lights for ABS problems. Saw there was recalls for the 2019-2022 and saw there was a class action law suit for the 2018 models.
Abs problems due to HCU
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.
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
Abs, traction control lights on, defective hydraulic control unit. Second time it has gone bad, warrenty the first time, needs to be replaced again, need to look into a safety recall.
