Owner reports filed with NHTSA about this vehicle, newest first and reproduced as filed. They are unverified accounts: one proves nothing, and a pattern across many is the thing worth reading. Back to the full 2018 record →
ABS & Traction control light keeps coming on. Believe this is a safety issue. My research has shown this to be a major problem with vehicles like mine and the parts are not available. My family and I use this vehicle to tow a camper and I feel that the manufacturer should issue a recall and repair since this is a known safety issue. This started approximately one month ago and is continuing to get worse.
Service electronic brake system and ABS system
I purchased the subject vehicle in NEW condition in September 2019. On April 2021 the vehicle ABS lights came on and off. The mileage of the vehicle at that time was 16,538. I took the vehicle in to get serviced by ANCIRA Chrysler Jeep Dodge Ram dealership and the HCU PUMP was replaced. I have the service invoice that has all this information. On August 20, 2023, the same lights came on. The vehicle now has 48,000 miles on it. As a part time mechanic, I conducted a diagnostic test and found that the error code is the same as the initial incident, which is Code C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRIC FAILURE. The vehicle no longer as a warranty and since there are no available parts available for repair, I have no choice but to drive this truck putting myself and my family in danger. The vehicle is available for inspection if needed.
ABS and Traction Control warning lamps lit with chime. Vehicle scan shows abs pump failure, confirmed by an independent service center. Loss of antilock braking, traction control, and cruise control.
ABS traction control, light code c0034
The abs module and abs pump has failed for a second time. Anti lock brakes do not work or traction control with lights on in dash The message appeared 2 years ago. Bought the parts and dealer fixed it. Now the message is coming up again.
Service electronic braking system light comes on intermittently every 1-5 minutes while driving. Also, a light indicating issues with the traction control system comes on. ABS system seems to be failing or indicating failure almost constantly. Cruise control is disabled during these times. I've read this is a common problem with these vehicles. There really needs to be a recall issued for this. Is my truck safe to drive if the braking system functionality is in question? Not really.
My ABS and Traction control lights activated visually and with audible alarms. I brought it to the dealer. It only has 23,000 miles on it with a manufacturer extended warranty. The dealer told me that the ABS pump motor control as well as the HCU has failed and need to be replaced. They also told me that the parts are not going to be available until the EARLIEST February of 2024. The vehicle is not safe to drive without these safety systems working especially towing. They told me the parts are under Engineering review. They suggested I park the vehicle until parts are available. NOT ACCEPTABLE!!! I have looked at owner forums and this issue is common and needs to be addressed by NHTSA and the vehicles recalled due to safety.
Service ABS system and traction control light continually flashes on and off. Does not allow me to use cruise control and it also turns off my ABS which is unsafe.
Abs system lights keep coming on even without system needing fixed.
The service anti lock brake system light is on, the service electronic braking system light is on. This causes the ABS, traction control and cruise control not to work.
The “service electronic braking system” light is on, also the “service antilock brake system” light is on as well.This causes the ABS, traction control, or cruise control to not work The truck has 49,000 miles
ABS failed, brakes locked up causing truck to skid out of control
My vehicle keeps throwing up a service ABS and service electronic braking system intermittently and the braking system is greatly diminished. Vehicle has been inspected and the replacement parts for the breaking system are on national back order without a recall open.
The contact owns a 2018 Ram 2500. The contact stated that on several occasions while driving at various speeds, the ABS and traction control warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed that the ABS controller and ABS pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 70,000.
My ABS / Electronic Stability control warning lights keep coming on intermittently and also sometimes staying on for hours at a time. I cannot use my cruise and my ABS will not work with these problems making this a very dangerous truck to drive. I have read that there are many other trucks with this issue. More specficially the 2017-2018 Ram 2500's. I believe there should be a recall for these parts as this is a intergral function in these HD trucks.
ABS module and HCU module are at fault. Have been driving it and lights and dings will come on and off at random. When lights are on I cannot use electric brakes for my trailers either. Dangerous when I’m hauling live horses and no trailer brakes. This is a common issue that Chrysler refuses to recall.
Abs HCU failure. This is a know common issue and yet no recall. THIS IS NOT SAFE
The HCU and ABS modules are defetive. This has been a safety issue as the ABS system is inoperable. The parts are finally available. However, it will cost $2000.00 for repairs since the vehicle is out of warranty. Should this not be a recall?
Ram 2018 ABS pump failure. No abs, no traction control. Dealer states no parts until,maybe, Feb 2024. Service manager stated do not drive as brakes could/may totally fail. Web search shows common issue with 2018 Rams.
"Service Electronic Braking System", & "Service Anti-Lock Braking System" indicators flash & ding constantly. Started on 8/15/23. Vehicle can be available for inspection. It has not been inspected by a licensed mechanic yet. ABS, & Traction Control lights on the cluster are lit up.
Drivers side battery died, after replacement of the battery, the ABS ,traction control lights came on and off with display of "service ABS system" in the display center. this has continued to flash with audible warning ever since battery replacement.
ABS and Traction Control warning lights on dash, go off and come back on. Truck was in cruise control with exhaust brake on and tow/haul mode engaged. ABS/Traction control light flashed on, truck dropped out of cruise control, exhaust brake came on car following the truck almost collided with my rear bumper. This is a dangerous situation, it is also affecting the cruise control. The dash board ABS and Traction control light cycle on and off, however this last few days they have been on more than they are off. This needs to be fixed at no charge by RAM trucks.
The contact owns a 2018 Ram 2500. The contact stated that while driving approximately 68 MPH and hauling a gooseneck trailer, the ABS system became inoperable. The vehicle was taken to the local dealer, where it was diagnosed that the ABS module needed to be replaced. The vehicle was repaired, but the failure recurred. The contact stated while her husband was driving approximately 55 MPH, the ABS system became inoperable. The ABS, traction, and engine warning lights were illuminated. There was an abnormal dinging sound detected. Additionally, the cruise control was inoperable. The vehicle was taken to another local dealer, Findlay Chrysler Dodge Jeep Ram (10305 US-224, Findlay, OH 45840), where it was diagnosed that the ABS module and hydraulic system needed to be replaced; however, the vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 60,000.
Anti-lock braking system and Hydraulic Control Unit were replaced on my truck. The original parts are defective, and many owners of 2017-2018 Ram 2500 and 3500 trucks have had the same issue.
My Vehicle along with thousands (maybe hundreds of thousands as I have been looking on internet ) has antilock brake warning buzzer on that will not go off and I only have 25000 miles on it. It is out of warranty with Ram but I know this should be fixed as I am Leary to drive a vehicle with a brake warning light and warning buzzer constantly going off while driving. If the brakes fail these trucks could kill someone or kill the driver when they cannot stop.
ABS / traction control intermittent failures.
"Service Anti-Lock Brake System/ Service Electronic Brake System light continues to chime. Mechanic has inspected, cleaned, and die-electric greased the connectors. Light stays off until the first bump. It is unknown if the ABS is operating properly and may lead to accident or death if not corrected.
My truck is getting a periodic message to service the ABS system as well as the Electronic Braking System. After doing some research, I see that RAM is the defendant of a class action lawsuit over this issue and the NHTSA is doing an investigation into several people having these issues. I took my truck to a dealership -- they said my truck needs an ABS control module and brake control module. However, the parts are not available and Ram does not know whey they will be available. The dealership told me it could be six months or more before parts are available but my truck "should" be safe to drive. I own this heavy duty truck because I tow a travel trailer. I cannot tow anything with a vehicle that has a failing braking system.
Service abs system, abs light and traction control light flash on and off intermittently indicating possible faulty HCU and ABS Module installed from factory causing the abs system to fail along with the traction control system and loss of cruise control . My safety and others are put in danger with the brake system not being allowed to work properly
ABS light/service electronic brake system. Dealer advised that ABS actuator and hydraulic controller unit needs to be replaced. Items are on back order and can not be ordered until released by Chrysler in February 2024. In the meantime no one can tell me if it is safe to drive my truck or not.

The ABS and traction control light is flashing on and off, this truck has 57000 miles on it and is garage kept. I looked it up and many of these trucks are having the same problem. The dealer wants $200 just to verify the problem. It is unreasonable that the ABS system fails so quickly in these trucks. The ABS/traction control lights will also come on and stay on for a while and then go off.

The abs and traction control lights stay illuminated on dash. No abs, traction control, or cruise control. Abs module looks to be the problem
Antilock brake controller malfunctioning. After a quick google I see this is a a very common issue so I’m confused as to why it’s not a “recall” item. Thanks for your assistance.
Faults for the ABS (anti-lock brake system) and EBS (electronic braking system) have been coming on intermittently for a couple months. Now the faults are permanently on indicating the ABS and EBS needs serviced. The fault code is c0020-01which indicates the known malfunction involving the anti lock brake system module and anti lock brake system control. While these faults are present the cruise control also doesn’t work. This is a well documented and known issue with certain model years Ram 2500 and 3500. My truck had approximately 57,000 miles when the faults began.

Our backup camera glitches all the time and doesn’t disengage when it should
ABS and SERVICE ANTI-LOCK BRAKE SYSTEM warning lights randomly turn on while driving and cause loss of ABS braking and traction control, this is dangerous on slick roads.
ABS failure warning light comes on randomly. While it is on, cruise control is disabled. RAM dealer examined truck and determined HCU pump needs to be replaced, but the manufacturer will not allow them to order this part as it is on "engineering review" until at least February 2024. Called RAM Care and they said "there is nothing we can do". When pressed for where to take my appeal to, the only further contact given was a PO Box in Michigan. Not being able to drive a truck I paid $75K for seven months is unacceptable!
NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
