Service electronic braking system / service ABS light comes on and off when driving on on bumpy roads and when turning. It usually stays on which disables traction and it has cause me to almost spin out when accelerating in wet conditions.

Service electronic braking system continues to flash along with Service Antilock brake system--This is a failure of the HCU (hydrolic control unit) that should be a RECALL. Thousands of people are having the same issue.
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.
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.
ABS needs service. Was quoted 2k from Dodge for repairs. As well as electric brake system not working Chrysler told me it is safe to tow my 10000 lbs rv with the errors and no ABS.
ABS service light was intermittently coming on and off for a period of time and now is constantly on. This results in constant beeping and also prevents the cruise control from working.
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.
Constant on and off of abs and traction control due to abs module and hydraulic control unit failure. It’s a known issue by fca.
ABS and traction control modules randomly deactivate leaving 20,000 LBS of truck and trailer without the ABS and traction control system to aid in emergency stopping. This is A KNOWN ISSUE to Ram who refuses to acknowledge and properly recall and provide replacement parts on some of the most heavily used tow vehicles.
Truck chimes and says service ABS brake system and service electronic brake system. Traction control and ABS light pop on and off intermittently while driving.
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!!!
Second time my antilock brakes module has gone bad with 56000 miles not covered under warranty. Cost me $1700 to fix a little over two years ago. It went out again today and they said they wouldn't cover it. I have been reading about this and it's a major problem with many Ram trucks. I feel it should be taken care of on a recall and not having to pay every time it goes out. Ram knows this is a big problem and not doing anything but taking my money. Thank you
ABS control module fault code. Seems to be a lot of people having issues with this on 2017 and 2018 year model trucks. A class action would be nice or some sore of solution for ram to make a permanent fix.
Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. Both the ABS and traction control lights are illuminated. I contacted my local dealer and they indicated that this isn't an immediate safety concern and is due to an electrical issue for which they haven't solved. They quoted me $1,600 for the replacement of the Anti-Lock Brake System Module and Hydraulic Control Unit. After some online research, it seems that this is a common issue with many resulting in total brake failures. A potential brake system failure should be a recall for obvious reasons.
The issue with the Electronic Braking System and ABS has worsened. The two warning lamps are almost constantly on, or rapidly come on and go off rapidly. If I'm towing a trailer, all braking is lost momentarily - brake pedal to the floor - including the trailer brakes. The trailer brakes do not return until an ignition cycle, if the warning lamps stay off, that is. The dealer says no parts are available, but won't even take it in for troubleshooting or attempted repair. This truck scares me. This has been an issue for about two years and 20,000 miles.
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.
Service Electronic Braking System and Service Antilock Braking System lights have been popping on the dash for the last two months nonstop at random times. Sometimes I can drive for hours and not see them, then other times they flicker on and off constantly. It’s very frustrating as my truck has only 27000 miles for a 2018. I’ve checked rear wheel sensors and found a tiny bit of metal shavings which from what I’ve read could be wheel bearings but still don’t know a for sure answer. I’m about tired of chasing down this rabbit trail. What caused this was I was backing my trailer and I started to spin a little and the lights came on so I clicked into 4x4 and lights stayed on. I turned the truck off and thought nothing of it and next morning truck had no lights on that day. But ever since then I’ve been plagued with them going on and off.
ABS control module/pump very common problem with this year truck that Fiat/Stellantis needs to address.
Abs traction control light
error code c0020-01abs/hcu pump motor control. i am one of thousands with the problem of getting abs and traction control lights flashing on my dash of my truck. it takes away my abs brakes my cruise control and the trailer brakes. i use my truck to pull a large trailer which has forced me to stop using my truck and it is now useless to me.please help us all and force ram to recall and fix our problem. my truck is a 2018 2500 and has 18,000 miles on it. and now i can not use it.
C0020 error code. Required replacement of ABS system's HCU (hydraulic control unit). Vehicle's ABS and electronic braking systems warning systems would flash. Loss of cruise control when the warning light came on. Vehicle lacked ABS made especially dangerous in wet road conditions while towing.
This complaint is the same as many seen by googling this problem. There’s a beep and then the ABS and traction control light come on. Message is given to service abs system. Then the message goes off and returns a few seconds later. this happens consistently during the driving duration. This only happens about every other driving session, but when it happens, it’s consistent. This is a known incident that is happening in 200s perhaps thousands of drivers. It sounds like a malfunctioning part to me, plus I have no idea if I have a real issue. I called ram care with no help.
ABS and TCS modules failing cruise control and abs unavailable when lights appear on dash. Vehicle not inspected by authorities or dealer at the moment will take to service center shortly.
ABS Pump Motor Control: General Electrical Failure code-C0020-01
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!
Driving the vehicle the alarm dinged and the panel displayed service ABS system, service electronic breaking system. Would go off and on flashing intermittently
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
For the last 3 years the ABS and traction control warning lights come on and off intermittently. This occures every time the truck is driven. I have replaced the ABS control module and the Hydraulic pump unit with new OEM parts and this issue keeps coming back. Driving and towing heavy loads this truck is extremely dangerous (without a functioning ABS system). A recall is urgently needed!!!
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.
