Vehicles “service antilock breaks” code is flashing. Began doing this with under 15,000 miles. The cruise control and the anti lock breaks don’t operate as a result. Problem started as intermittent and is now a constant issue. It appears to be the hydraulic break control unit, and is a very common issue with this year of truck.

Page 9 of 10: complaints 221 to 250 of 253, newest first, as owners wrote them.
The ABS and traction control service lights and alarm come on and off and shuts off cruise control. stops coming on for days at a time then happens again. Been told brakes could lock up and trailer brakes may not work
Vehicle has had multiple failures of the ABS system. One failure occurred while under warranty at 14,228 miles, but a subsequent failure at 45,994 miles is stated as "not covered" under standard or safety-related warranty. In the first failure, the "CONTROL A 68143491-AA" was replaced. For the second failure, "CONTROL A 68143491-AB" and "Module AN 68347098-AB" are to be replaced. The replacement has not occurred as of this date (3 months post diagnostic) due to a shortage of parts. It is claimed that there are so many failures of these parts and the pass-rate during manufacturing inspection is so poor that a resolution time for my primary vehicle is unknown. The quoted cost of this safety-related epidemic problem is near $2000 or almost 4% of the cost-new of the vehicle.
Abs service light came on for the second time. I took it in to the dealer they replaced a part and now its back on and off.
Code for right rear wheel speed sensor came on. Resulting in no abs,traction control, 4x4,or parking sensors. I bought new part from dealer had mechanic change it. Reflash abs and still on. Went off briefly for 5 seconds came back on. I've realized it's it's common problem. Resulting in the abs module needing replaced. But it's only a temporary fix.
At 36,100 miles I started getting ABS light warning flashing intermittently on my dash. I took it to a mechanic who told me it needed a ABS module and/or a controller device replacement but these parts have been on back order for the last four months (says RAM). It looks as if many, many people are having this same problem with this vehicle. This problem resigns the vehicle as inoperable since it involves a braking component that is obviously a safety issue. This is my only vehicle so I MUST drive it at times which makes me very nervous.
At 67k mileage my 2018 Ram 2500 abs, traction control and electronic braking system warning lights flash intermittently, dealer, auto parts store and several online sites state it is the ABS and HCU modules electrical failure. This causes the abs system to malfunction and poses immediate threat for crash especially while pulling trailers. When the lights flash the cruise control will no engage/disengage. No dealer has these module with no clear indication of availability as of 1/27/2023
While the vehicle was still in warranty ~30k miles, the ABS and traction control lights would flash off and on numerous times as the vehicle was driven. Knocking the cruise control off. The dealership replaced the ABS module and HCU. Less than 20k miles later the issue has come back again. The alarms and lights flash repeatedly every time I drive and traction control along with the cruise control is unavailable. Now the truck is out of warranty, and this is over $1000 to replace. This is a known and well documented issue with Ram and needs to be looked at for a recall. The parts are backordered for 9-12 months. And the replacement does not fix the issue.
Anti lock brakes are on and no towing brakes. Replaced hydraulic control unit and ABS control module. Message showing service anti lock and ABS. Dash continually ding to service. Unable to reset.
Service ABS and traction control warnings go on and off, on and off, on and off etc to the point where the vehicle isn’t drivable. The truck has only 14k miles and is out of warranty. Took it to the dealer, they said it is a known issue and that the ABS hydraulic control unit needs replacing but it is on back order until at least January of 2023. So now I have a $60k truck that is not safe to drive and can’t even get it fixed.
The contact owns a 2018 Ram 2500. The contact stated while driving 40 MPH, the ABS and traction control warning lights started flashing. The vehicle was taken to an Auto Zone to be diagnosed; however, the cause of the failure was not determined. The manufacturer was not contacted. The approximate failure mileage was 90,000.
Service electronic brake system and service antilock brake system comes on intermittently which disables traction , cruise and antilock brake control systems when it happens, very dangerous in slippery weather
Brakes seem to be intermittent. Check Electric Brake warning comes on every time you start the truck and has shutdown the ABS and cruise control options. This is a very big problem if you research it on the internet on Ram and Mopar forums.
The truck ABS, traction control, and service electric brake lights and warnings have flashed and beeped on and off and on and off every few seconds. I took the truck to the dealer to be fixed under warranty. The dealer states it has a bad HCU and no longer has anti lock brakes however I can still drive the truck with all that distraction going on in the dash. The part is on back order and I won’t have my truck repaired until February (2.5 months) This same part was also replaced a a little over year ago under warranty along with Abs sensors and wire harnesses. I have 2 friends with the same year trucks who also had to have the same repair done. Upon looking up information on the internet it seems like this has been a on going issue on the 4th generation ram trucks 1500-3500 models from 2012-2018 I feel the safety of this could cause a car accident by the distraction of the dash going nuts and the possibility of a vehicle skid while not having anti lock brakes properly working. I would hate to drive it putting my life as well as others drivers and passengers lives in the line due to this safety issue ram is having. The issue happens randomly some times non stop while driving and sometimes I can drive 15 miles or so with nothing then it will start again. It first happened when I had approximately 50,000 miles on the truck and has done it again at 73,500 miles. When the lights are on it will not allow cruise control to work or 4x4 to engage. I have not noticed anything else not working properly.
The ABS control module has begun failing sporadically while the vehicle is running. When this happens is disables the traction control system and the ABS system until the alarm clears, and if the vehicles cruise control is on, it immediately disengages. All of these symptoms deteriorate the safety margin of the vehicle, and cause mid-driving malfunctions that can be unpredictable. When the module is malfunctions both the ABS warning light and TCS warning light are illuminated and a text warning is displayed on the multifunction display of the gauge cluster. The contact found that the parts to rectify this issue are being rationed by Stellantis, leading to unacceptable lead times in simply procuring the parts. When added to the shop rates charged to fix this issue, the price of replacing this clearly defective component begins to total in the thousands of dollars. Therefore, in order to continue his profession and responsibly take care of my liabilities, operating a four-ton vehicle with a compromised braking system and have done so for two years now. In addition, the ABS Malfunction Indicator chimes repeatedly while driving, creating an endlessly distracting environment.
The contact owns a 2018 RAM 2500. The contact stated that the ABS and traction control warning lights illuminated continuously. The contact stated that the failure indicated that the ABS system and the trailer brakes needed to be serviced. The contact took the vehicle to the dealer to be diagnosed. The contact was informed that the ABS pump and ABS module had failed and needed to be replaced. The vehicle had not been repaired due to parts being on back order. The manufacturer was made aware of the failure and referred the contact to the federal safety agency Hotline for assistance. The approximate failure mileage was 65,000.
ABS Module & Hydraulic control unit
ABS Module and HCU bad with 40K miles, a WELL KNOWN ram issue that they continue to ignore and take thousands of Additional dollars out of consumers pockets as they seem to go bad JUST after the basic warranty expires. 70 thousand dollar truck that is garbage, and Ram won’t remedy this problem. Second power wagon I’ve owned, same issue, similar mileage.
ABS and HCU module failure on a vehicle with less than 50,000 miles on it following all maintenance intervals and instructions. Results in traction control and automatic emergency braking not working as intended. Parts are backordered until January at the earliest, and will be over $1k after labor.
The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the “Service Electronic Braking System" and the Traction Control icon were illuminated. During the failure the cruise control would independently be deactivated. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure but no assistance was offered. The failure mileage was 9,000. The consumer stated when the vehicle is started and placed into gear, "Service Electronic Braking System, Traction Control, and Anti Lock Icons" all illuminate. The manufacturer stated the vehicle is out of warranty and if fixed it will be at the owner's expense.
ABS and Traction Control warning light keeps intermittently coming on and then a message saying that the Electric Brake system needs serviced. This has happened to my 2018 RAM at 17,000 miles. Dealer replaced ABS module under warranty and problem was solved. Now I am at 35,000 miles and the problem is back. Same exact issue. This needs to be a recall item ASAP and this seems to be a VERY common problem with these trucks. This could be very dangerous as these trucks are made for towing heavy loads and losing your anti-lock braking capabilities could be catastrophic to you or anyone else on the road.
Service Electronic Braking system and Service ABS braking system messages with accompanying chimes occur every 2-3 seconds while driving. This turns off the traction control and abs as well as the speed control. Diagnosis reveals abs control module and hydraulic brake control unit needs to be replaced. Code c0020-01,Vehicle only has 22,000 miles. Parts are discontinued according to dealer site. I started getting a Service Electronic Braking System warning light and bell recently that is intermittent and seems to affect the braking system on the truck. The light will go off and then return, sometimes once and at other times frequently. I searched online for this issue and found this is common among the 2018 and later year RAM trucks. The dealers make repairs under the warranty or charge upwards of $1,000 to change components to clear the warning, sometimes resolving the issue and at other times the warning returns shortly after repairs were made. My truck has just over 22K miles and the warranty (36 months) lapsed in October 2021. I believe RAM has adequate historical information regarding this issue to recall these vehicles and replace the failing components impacting safe braking on these trucks. Some vehicles exhibited this warning with less than 10,000 miles on them. There is plenty of owners complaints available via internet sites, such as the RAM Forum, documenting this safety issue and the lack of support by Chrysler to resolve the problem. FCA RamCares was at no help at all, and kept referring to recall V06, which is the drag link welding of jam nuts, which is also a hack job of a recall.
The abs pump and module have failed on my vehicle leaving it without abs, skid control and traction control. This is a very common issue and known by the dealers and manufacturer. This has affected tens of thousands of Ram trucks anywhere from 1 year old to 4 years old. But is only covered under warranty 3 years or 36k miles. It is my opinion this is a safety concern and should be recalled by the manufacturer.

Intermittent alert on ABS and Traction Control warnings. These warnings are not consistent and come on/off. Researched and found numerous issues on this model vehicle for same issue related to ABS/Traction Control pump. Checked the speed sensors, all are working and reporting same speed. Dealer wants 2 days to trouble-shoot and there is no guarantee this will not return. I have owned other vehicles - GMC, Ford, Subaru, etc - none of them have failed on a critical item like ABS/Traction Control.
Randomly my 2018 ram 2500 ABS/Traction control go out. It’ll happen for 10mins in an out. Sometimes not at all, and others all the time. When the ABS and traction control like come on and off on the dash it causes the brakes to become spongy and harder to brake.
The service anti-lock brake system light keep coming on and off on dash, sometimes every few minutes then it could be days before it happens again. Diagnostics code reader is listing C0020-01 - ABS Pump Motor Control General Electric Failure
8.4 Uconnect (media center) screen delamination causing "ghost touches"/glitches on the touchscreen, which prevent backup camera from functioning. While backing up, camera randomly turns off or switches to a separate cargo camera. Backup camera often remains on while driving forward. Ghost touching also cause random phone calls and emergency phone calls, which cause a distraction to driving. According to simple Google search, 8.4 Uconnect screen delamination appears to be a common problem even on low-mileage vehicles. Manufacturer/dealer will not replace outside of warranty.
While driving my 2018 Ram 2500, the Service Electrical Breaking System and Service Anti-locking Break System flashes on and off. It usually does this while traveling on a bumpy road or driving over railroad tracks. Sometimes it will go days without coming on and some days while driving it constantly beeps and flashes the entire time while driving and it really distracts me from driving. When I called my local Ram dealership Lander's Dodge Bossier City, to make an appointment, they knew that it was a 2018 Ram 2500 before I told them. The first available appointment isn't until 22 November 21.
