Warning lights for ABS and traction control coming on with message to 'Service Electronic Braking System'. During this time the ABS does not work and cruise control stops working. Being a 2500 vehicle, it is commonly used for towing trailers as it has a towing capacity up to ~16K lbs. Suddenly not having ABS and traction control is dangerous. In July 2024 I was driving from Phoenix, AZ to East Texas with a ~10K lbs trailer and this issue suddenly started popping up. This is the first time I experienced this with this vehicle. I understand there is a known issue with the hydraulic control unit and the ABS modules for 2017-2018 2500 & 3500 models yet there has been no recall on these vehicles.

The ABS dash light and traction control light started coming on about a year ago. the light is intermittent with a ding sound. Some days it comes on non stop, sometimes it doesn’t come on at all. cruise control does not work, and “park rear” button is not able to get out of the off mode.
Driving on interstate highway with cruise control engaged. Experienced rapid deceleration as cruise control disengaged without driver input. Received anti-lock braking error / service electronic braking system error. Was very dangerous situation to have occur unexpectedly and could have easily resulted in rear end collision or loss of control of vehicle. Received no warning prior to this failure. Issue has been sporadic but occurring more frequently. Vehicle has less effective braking in adverse road conditions. Never know when the anti lock brake system will be functional. A bump or vibration in the road can cause it to engage or disengage. Ram dealer service dept indicates Hydraulic Control Unit needs to be replaced. Looking online, I see this is an exceptionally common occurence in same year/make vehicles. So much so that the replacement part is backordered for months.
While driving the PU with my camper in tow, the ABS and Service electronic bakes system warning were displayed on my dash. Then they went out. This process repeated several times over the next 3-4 minutes. Then the warning lights came on and stayed on. It remained that way until I parked on the side of the road and turned off the vehicle. I checked the undercarriage for any signs of any visible damage to the braking system. None was readily identifiable. Upon restarting the vehicle, all warning lights were extinguished. I proceeded to the campgrounds with out further warnings on this system. The next day, with out the camper in tow, the warning lights were again active flashing on and off for a period of about 3-4 minutes before they again came on and stayed on. This process repeated itself as I would turn off the vehicle and then restart it. Upon parking for the evening they were still on. When I started again the next day, they were off.
ABS/traction control warning lights and alarm intermittently on and off during driving, speed control does not work during the alarm cycle. ABS not working when warning comes on
It's clear that my abs module is bad but it consists of three components. Mopar online doesn't have any components available to fix the problem. And the Dealer is selling the components separately and telling you which one they will sell you first and also at a higher price than what's available to you online
ABS and TRACTION CONTROL warning lights appear and disappear. Timing of warning lights have no discernable pattern. Vehicle has had no collisions and only 120,000 miles. Vehicle will be going in for inspection at garage.
Thai dang ABS going out in these trucks. And still no fix. Went out when going down the high way. Kicked out Cruze co trip 4 we and all sensors. Almost died this is crap that nothing is being done to fix this and get a part that fixes this for the customers that bought these trucks. I have a 50k truck I can’t drive. Have not driven it’s in almost a year now. SOMETHINGS NEEDS DONE
Abs module failure causing cruise control shutdowns and potentially causing an accident as well as transmission issues. Yes it’s been confirmed by an independent shop . Not by any others. No warning before just straight failure. Vehicle is available currently for inspection if wanted
My ABS light came on and then shortly later I noticed that my stability control system was disabled and its warning light came on. I also lost the ability to use my cruise control. Took vehicle to the dealer and they determined that the ABS Control unit needed to be replaced. They trouble shot the issue and replaced the ABS Hydraulic Control unit. This repair is for the same recall as 85B for Ram 1500's.
Continually getting ABS warning and "Service electronic brake system soon" warning. Electronic Stability Control suddenly shuts off without warning to include cruise control if engaged. ABS and ESC lights remain on most of the time with constant chiming. This is a widely known problem. Recall just came out for later model years but not these.
The ABS warning light and alarm come on while driving. Loss of ABS and cruise control, near rear end collision by following vehicles on the freeway while using cruise control. Ram knows they have a problem with 2017 and 2018 2500 pickups. Why no recall? Safety problem!
Abs light and traction control warning light constantly coming on and off while driving and a warning sound playing every time the lights come on in the dash, which is very annoying and frustrating. The truck is under 30 000 miles and unfortunately is out of warranty. I don’t drive this truck very much and having this kind of problems with it is totally unacceptable.
Vehicle will display Service Electronic braking system randomly throughout driving the vehicle. The cruise control is not available when the code shows up. Also, the ABS and Traction Control lights pop up. The problem will shortly go away when I press the brakes all the way.
Vehicle has a control module failure causing the ABS, Traction Control, Cruise Control and other braking systems to intermittently turn off and on. The vehicle has been brought in for this issue and we have been told they are unable to get parts to replace the module at this time. This has been an ongoing issue for multiple years, with the failure occurring at a higher percentage of time the vehicle is driven now.
I bought my 2018 Ram Truck in 2019 new from a dealership. the first sign of a problem started at about 25,000 mi. It started sending tones with the message "Service Electronic Braking System" and "Service Antilock Brake System". It would toggle between these two messages and sound warning tones while the truck is in operation. The first shop I took it to replaced my carburetor. That was not it. I then took to a Diagnostic Shop and the message from the computer read: ABS pump motor control general electrical failure. On the dash it also shows the icon for slippery road conditions. Looking on the internet i realized that this is affecting 2017's and 2018's. There are a lot, maybe all of them being affected by this potentially dangerous malfunction.
Driving on cruise control the Anti-Lock brake light came on causing the cruise control to turn off at highway speeds. The anti-lock brake system, cruise control and traction control all quit working. Warning light went out and then all started working again. Very intermittent problem at first then started getting more frequent. After research I found it is a known problem on 2017 and 2018 ram pickups. The parts to fix it are revisions from the original and known bad but no service bulletins or recalls. There has been a recall for 2019 and later but Ram is not addressing the earlier problems.
Brake module malfunction kicks out cruise control and dings constantly. Seems to be a recall for other years but this year is missing?
Two issues with my truck. #1. The ABS HCU was replaced under warranty once. I am now at 75k miles and it is doing the same thing again. Difference is I'm having to pay for it. #2. The Clock Springs has been replaced once already and now needs it again. I paid the first time and am now having to pay again!!! Absolutely not acceptable!!!
ABS pump motor control and anti-lock brake hydraulic unit is out again. first time replaced at dealer on 12/27/2019 second time8/10/2022 and now ABS light flashing again for about 3 weeks now with code c0020-01. This should be a recall it is very dangerous to be hauling heavy equipment with this reoccurring problem approximately every 20,000 miles or so.
Code C0020-01 appears and ABS service light appears - the vehicle is equipped with a defective and dangerous hydraulic control unit (HCU) module and anti-lock braking system (ABS) module. Anti-lock braking, traction control and speed (cruise) control are inoperable. Causing a safety concern
The Service Anti-lock Braking System warning lights and audio alarms come on almost constantly at times along with the cruise control failing, a common problem I understand which Dodge Ram has to be aware of. This truck has only 7000 miles on it!
Abs module failure. Traction control failure Stability control failure. Module replaced by dealer once under warranty and failed a little over a year later. Dealer would not replace defective unit stating it was out of warranty.
My abs system is not working the ETC is not working was told this is because of the abs pump and abs computer. Most safety components related to brakes not working. There are over a thousand complaints to Chrysler about these trucks and still no recall. Please help.
The "Service Electronic Braking System" warning comes on and off intermittently with an annoying "DING" while driving. It never stays on and always just comes on, DING, and goes away but repeatedly. It will eventually go away after driving a bit but then comes back unexpectedly. This also disables the Cruise Control. There are tons of complaints throughout the RAM forums and I see a lot of complaints filed here on the federal safety agency. The dealer is obviously very aware of the problem as the replacement parts are not available except for months of waiting, if at all. The dealership has not only stated the part is a long lead item and on back-order but it will be $1200 to $1600 for replacement and that part may fail as well!
The abs control module and HCU are faulty . No parts have been available for a fix. I have now been driving a truck in the north with no ABS , 4 wheel drive, cruise control or traction control. This truck is a hazard to everyone on the road but with no parts it’s hard to fix it. I only have one vehicle. Tons of people have the same issue and nothing is being done. Ram won’t do anything, stallantis wont do anything. It’s just crazy
Getting the Service Electronic Brake System, Traction Control, and Anti-lock Brake System. First noticed these alarms a couple years ago but they cleared by themselves. Sometime this 2024 Spring, around 70k miles these alarms started again. This time the alarms are nuisance going on and off multiple time a minute all by itself. Cruise control won’t work when alarms are on. When I checked forums, seems like there is a problem with these modules. The supply of the parts is a problem also. I ordered the parts from Mopar and after I paid for the parts and received an order number. The next day Mopar cancelled my order tell me to go to the dealer. Seems like Mopar is monopolizing these parts.
2018 Dodge 2500 w 75K miles. "Service ABS" and "Service Electronic Braking System" warning lights coming on intermittently for appx last 1.5K miles. When this happens, it disengages the cruise control when set, or keeps it from being engaged when unset . Noted yesterday that Braking performance is now lessened- slightly increased stopping distance noted when pulling an appx 3K lb trailer (no trailer brakes), which i regularly tow. Brake fluid levels good, brake shoes/calipers/rotors in very good shape.
