2018 RAM 2500 Electrical System Problems

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).

Vehicle showing Electronic Brake System as well as Antilock Brake system and traction control system not working. Pinging all the time, currently 165,000 miles on truck. Same issue was dealt with on 8/15/2020 with 39512 miles on truck. Was an out of pocket expense for $927.10 to fix this very important safety related issue. The cruise control is also affected by these messages and will not work. This is known issue around the country with these trucks and something must be done. If folks don't have money to fix or parts to get fixed we will just drive these safety hazards down the highways and jeopardize ourselves and others. What is your fix to this known problem because you all obviously are not correcting the issue for the known problem.

Hcu system failed now trucks and system is messed up, can’t use cruise control and nervous too drive the truck for safety reasons. Dealer says it could be months for a new system

Service electronic brakes, traction control, and service trailer brakes light stays on.

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.

At around 74,000 miles in December of 2023, a warning to "Service Electronic Braking System" and "Service Antilock Brake System" started to show up on the screen of my 2018 Ram 2500 6.7. The truck was taken to a Ram dealership and the fix to the problem was determined to be replacement of the ABS module in addition to replacement of the HCU. Apparently, the ABS module is faulty and is causing the HCU to go bad so both need to be replaced. Replacing only the HCU will not fix the problem. The truck has not yet been repaired as a new ABS module is not available until June of 2024. When driving, the on screen errors come up frequently at all driving speeds and the error is present the majority of the time while driving.

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

ABS system and traction control lights turn off and on intermittently. ABS pump and module have already been replaced and issue is still happening

ABS/HCU is a known issue for failure. Mine is intermittently flash alerts for service/problems. 1000’s of people are having these issues. Where is the recall? This is a safety issue, is it not.

Failed parts . #1 abs module #2 steering box & intermediate shaft #3 balljoints .available anytime for inspection? # 1 risk brakes locking up or soft pedal #2 steering wheel back and forth to stay on highway #3 knuckle fall off failed balljoint all causing an accident.. all independent shop for all components. Dealer for steering ?? Abs traction lights

Got a code for service abs system, abs module pump bad. Ram cannot even get people in to fix the issue and they want like 2000 dollars out the door to fix this unsafe issue. I also have no cruise control now and no abs. This is an absolute shame that my truck only has 66k mostly highway miles and is now worthless because I cannot afford to fix it. Ram will not fix this issue under warranty. There is a current lawsuit under James Neu vs. Fiat Chrysler to get them to make this a warranty issue and fix it. Please please please release the recall so we can get our trucks fixed! Thousands of trucks are affected and at risk of accident. Thankyou please let me know if there is any hope in the future of this recall. I don’t know if I should just wait it out...

As with thousands of other owners with this model of truck my anti-lock control module is bad. The malfunction causes the anti-lock brakes service light as well as the traction control service light to be on. This malfunction renders both systems to be inoperable, thus causing a major safety concern.

ABS & traction control lights on along with messages reading "Service Antilock braking system and Service Electronic Braking System. 1st intermittently then very often. Code C0020-01 is stored in the system via OBDII scanner. It is available for inspection at any time. I can not tow anything that requires trailer brakes because I here, through many other online complaints that trailer braking will be inhibited. I have not yet taken it to the dealer yet because it is out of warranty and the part required to fix it properly won't be built/available until Feb 2024. I first saw warning lights/messages in July of this year 2023 with around 37,000 miles. See attached pics.

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 control module had went out twice in 3 years and hydrolic unit causing brakes to fail

Took my Vehicle to dealer for abs and traction light displayed on dash. Dealer states my truck needs a new HCU and control module. At 28,000 miles these same parts had to be replaced for same issue. The truck now has 63,000 miles. To top it off abs, cruise control and 4x4 does not work or quits working when this warning is displayed. It’s absolutely ridiculous how many ram 2500-3500 owners are having this issue over and over. I would hope you all will step up and demand a recall be performed.

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

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.

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.

The radio screen has delaminating which causes random pushing of buttons on the display. This is a known issue with dodge radios and has been labeled as “ghost screen”. This is a major concern during the day as well at night while trying to drive. The distraction from the constant screen changing is a major concern. It is unavoidable to focus on the screen instead of the road while this is happening. Dodge knows of this problem and the repair cost is unaffordable. I feel for the safety of drivers and people on the road, this needs to be addressed. I have videos of this occurring but am not able to upload videos, only photos which do not show the event happening. I would like the chance to be contacted so I can share the video of this happening to express my concern, as well as the concern of many...

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 NHTSA. 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...

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...

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.

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.

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.

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.

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.

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.

Trucks and electronic braking and traction control randomly quits working.

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.

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.

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.

Abs problems due to HCU

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.

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.

Whenever it rains or is high humidity, my dashboard lights up and repeatedly chimes with ABS lights and Electronic Braking System error. The error repeats itself on and off again every few seconds. It is a dangerous distraction of error messages. Since it is raining, all traction control and ABS systems deactivate themselves with this error. I spun out this morning due to the error. It is absolutely dangerous. This is the EXACT error that occurred on my previous Ram. This is a dangerous faulty hydraulic control unit (and ABS system). Upon a little research, I found tens of thousands of posts of owners being stranded or driving without ABS / traction control due to this malfunction. This is deadly and needs to be recalled. RAM is aware of this issue but has not issued a recall. It is raining today, and my RAM will not have traction control or...
