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.

The system that is malfunctioning is the braking system, ABS module, or HCU. The traction control light and ABS light intermittently flash, disengage cruise control and the antilock braking system. The lights never stay on consistently but rather they come on and off without any pattern. This same issue happened a right at 2 years and 30k miles previously which the truck was then taken to a dealership and supposedly replaced. However, the same issues are happening again with no indication as to why this part keeps failing. Truck has less than 90k on it currently, mainly highway use. There have been no inspections done, however, I plan to take it to the dealer in the near future.
ABS been down since July,2023,alarm dings constantly, dealer says no parts available, and Chrysler is no help
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 light and braking system needs servicing and found out it is a common problem with Dodge Rams , scanner shows ABS pump motor control general electrical failure
“Service AntiLock Brake System” and “Service Electronic Braking System” lights flash intermittently while driving. ABS, Traction Control., and Engine lights up on dash. Code is C0020. It has done this several times while driving. Vehicle has just over 34,000 miles on odometer. Its a common issue apparently known by Stellantis and they had changed supplier and part number.
The ABS HCU has failed again this is the third time. The brakes feel spongy and the cruise control and 4wd does not work. The cause is unknown faulty design of parts. I don’t remember the mileage of the first or second failure.
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.
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.
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.
The anti-lock brake control unit failed while under warranty and was repaired and it has failed again with only 53737 mi. When the ABS light comes on the traction control light comes on and the cruise control quits working. Seems very unsafe. Don't know if I can afford to fix it and no parts are available.
When driving and hit a bump the abs/ traction control lights come on and off. Does this consistently with bumps. Problem is not a wheel hub or sensor, when scanned it comes back as a C0020-01 code abs pump motor control general electrical failure. Safe to assume that the brushes within pump motor are sticking and failing to slide properly.
Constant problem of service electronic braking system and traction control light going on and off. Has been happening for the last 6 months on a truck with only 25,000 miles on it.
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.
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.
At 41,000 miles “check abs and electronic brake system” warning started coming on causing system failure to vehicle. Vehicle was taken to dealer with it requiring replacement of Hydraulic Control Unit and ABS control unit. Now at 71,000 miles same problem is occurring with cruise control deactivating, traction control failure, and ABS failure without warning. Apparently this is a known issue by RAM that continues to cause system failures across the vehicles sold between 2017 and 2019. To date I’ve not had an accident due to this issue but it is definitely a safety issue that RAM should be forced to issue a recall to correct! Please respond with updates. Thank you…
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.
Brake module malfunction kicks out cruise control and dings constantly. Seems to be a recall for other years but this year is missing?
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.
Abs light comes on and off all the time. Randomly and hitting a bump. Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. It doesnt seem to matter what speed you are going. Upon research online looks to be a common problem that RAM has. There is an issue with pump motor electrical brushes making contact which causes this issue.
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.
My abs/traction control and electric braking system warning light has recently cone one for the third time. The first time it was repaired around 3,200 miles, the second time was around 32,000 miles and now around 72,000 miles. The light flases randomly and when it does i can't use my cruise control.My vehicle can be inspected any time.
Vehicle warning lights and message on dash keep going off and on indicating need to service the ABS system following a break-job. Warning comes and goes as many as 30 times per minute. Anti-lock brakes and traction control are currently inoperable. Dealer cannot diagnose between electronic ABS module and hydraulic control unit blames one or both as culprit. Module is on back-order from Mopar due to this being a widespread and prevailing issue and they even suggested the matter has been escalated to their engineers for a more robust solution. My ABS pump module was replaced under warranty at 90k miles. I was quoted $1800 to repair upon part availability. I would appreciate the federal safety agency investigating this matter for eligibility of a forced recall with Ram to pay some or all costs to remedy.
Abs light comes on and off all the time. Randomly and hitting a bump. Code is c0020-01. The cruise control is disabled when this occurs. Also I assume abs would be disabled also. Took truck to dealer to look at. They tell me there is no engineering fix at this time for this issue and no parts available. Upon research online looks to be a common problem that RAM has. There is an issue with pump motor electrical brushes making contact which causes this issue. Truck is a fairly low mile truck.
Driving in traffic a vehicle in front made a sudden emergency manuver. I braked to avoid, the ABS warning light flashed and beeped "service abs system". The failed abs system nearly caused an accident. Took to the dealer, and they replaced the failed abs module under warranty at 20k miles on truck. Now, with 34k miles it failed again. Parts are reported to be on national backorder. Friends with this model truck are experiencing similar failures. Fact that these trucks are often work trucks, towing etc make these failures very serious. I urge you folks to push Ram to recall these defective parts before someone is killed.
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.
