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 light and traction control light comes on and off all day long. Brakes will lock up if you’re using cruise control when the abs and traction control light come on. Both lights come on at the same time. The parts needed for this issue is on back order.
ABS/HCU second time malfunctioning. Causing no abs and no cruise control. Parts are on back order until feb 2023. Causing me not to be able to safely operate my vehicle
The ABS system is failing. The braking system is now uncertain for driving.
For thousands of miles and almost 2 years, my ABS constantly warns, then resets, then warns that service is required. Dealers across the country scan my truck and find code C0020-01 ABS PUMP MOTOR GENERAL FAILURE. This part has not been available for over 18 months and every dealer has said they have dozens of customers needing the same part/repair. Nationwide forums show this to be an ongoing issue with faulty parts, yet Stellantis has not issued a recall, nor have they provided any sort of remediation. Several have "off the record" suggested pulling the ABS PUMP fuse to provide temporary relief from the constant alarming of a bad part.
ABS warning light and service brake system light keep going on and off. Sometimes only occasionally and sometimes constantly going on and off. Service code 0020 indicates ABS computer and possibly hydraulic pump replacement is needed. Truck has less than 36000 miles when this started but it exceeds the 3 years warranty period. Dealers indicate parts are no longer available to make repairs. This needs to be a safety recall with parts available for repairs to be completed. I have had it inspected by an independent service center and they have continuously said parts are still not available since April 2023 when this problem first occurred and was diagnosed. I see many forums and some class action lawsuits online indicating I am not the only one with this issue.
Service anti-lock brake and traction control system warning lights intermittently flash. This also causes a dinging sound. Problem is persistent. Ram dealer says abs brake module and hydraulic units need to be replaced. Parts backordered until March which means I will have to drive an unsafe vehicle with the constant distraction of flashing lights and warning tones or park my vehicle for 4 months.
Service abs system and traction control lights come on and go off at random times. When the lights come on it disables cruise control. While driving it has come on and disabled the cruise on several occasions and is a hazard while driving. I have told I will need to replace the hydraulic control unit but is on back order with no eta on parts
My ABS/Traction Control warning lights have been coming on and off for some time. They come on for random lengths of time. I brought it to the dealer at the end of July when the lights had been on long enough for the dealer to plug a unit in to read the code. I believe they stated it needed a control unit/board. I made an appointment to fix it a week later. When I arrived they stated they did not have the part in stock and they would notify me when it came in. Later that day I received a call from the dealer stating that the part would not be available until February 2024 because engineers were working on a fix. I now have to wait at least 8 months for a fix. I have researched online forums and there have been complaints for several years on this problem. There also seems to be a class action suit over this in two states. To say this is a safety hazard is an understatement. At any time I can no longer have ABS/Traction Control. There is no reason for not demanding a recall to correct this dangerous safety issue.
My 2018 Ram 3500 had less than 36,000 miles when the anti-lock brake system and service electronic brake system alarms began randomly flashing. this happens now every few seconds and so speed/cruise control no longer functions, also anti-lock and skid prevention has failed. Dealers have 3 month back order on the Hydraulic Control Unit, leaving owners the choice of operating an unsafe vehicle, or parking it for months.
ABS and Traction control lights/audible warnings came on at about 25K miles on my 2018 Ram 3500 Dually truck. ABS control module and I think HCU were replaced under warranty. At about 50K the problem came back, ABS and Traction lights constantly coming on. Dealer said the issue is out of warranty now. Dealer said I'd have to pay a diagnostic fee, parts/labor, and computer re-program in the thousands. Dealer said because this is a common issue, and my truck was repaired once under warranty, that after the repairs they could file to see if the manufacturer would cover any of it. Even if I buy and replace the parts that have been back ordered, I'd have to pay thousands for the parts and to have the dealer program the parts to the truck. I have not repaired this yet, because I believe the parts are faulty and will need to be replaced every 25k miles. I've read about many people having these same issues with the brakes on these Ram trucks.
Truck gets a service electronic braking check engine light and disables traction control as well as the cruise control. The braking becomes disabled at random times. Taken the unit to the dealership just to be told the part has been backordered for over 2 years and that they cannot sell me the HBU to repair it. They said they could remove the unit and have it shipped off to be remanufactured but my truck will be inop for min 2 weeks. Was told the part I needed 68143491AB
ABS activator system and stability control out. Dodge has replacement parts but are not replacing or releasing at this time
UNKNOWN. abs pump problem
ABS and traction lights come on intermittently with the brakes feeling different.Diagnostic shows code C0020-01 which is apparently a very common issue with 2018 Rams.Dealer told me today(10-25-23) no part’s available at the earliest will be Feb. of 2024.This truck has 81000 miles on it and is my daily driver.I would hope Ram steps up and fixes problems at NO CHARGE for everyone effected.
The HCU /ABS lights go on and off and the truck feels like it brakes different. My safety is at risk because the brakes are not functioning properly No, this is a well known issue with these trucks. Nothing on my truck as been inspected by an outside source. The ABS light and the traction control light come on and off intermittently.
The ABS and traction control lights come on intermittinly.code c0020-01 for pump motor control was the diagnosis.This truck has a total of 8211 miles.
ABS /Traction Control Light Service Electronic Braking System Service Antilock Brake System Vehicle ABS malfunctions and makes it difficult to stop
In August 22 I replace the hydraulic control unit on this truck to fix the intermittent abs and traction control message and ding on my evic and now in October 23 I am getting the same intermittent messages again. I paid and did the repair back in august myself but now seems to be a delay in getting the parts. I bought the truck in December 2017 so if you average the miles the second HCU only has approximately 8000 miles on it. These parts should last longer than that. The truck has only 47000 total miles on it.
The ABS light and traction control light randomly come on. I loose breaking power from time to time. It is a known issue with these vehicles. Unfortunately there is no way to fix it at this time. All of the dealerships near me have the part on back order and have for well over 6 months. It’s not very fun to drive around with no reliable ABS and the possibility the brakes may fail. I do not drive my truck basically at all anymore. It is a 2018 with 44000 miles. There is no reason the ABS should have failed. The vehicle has been inspected and I was told that a new module was needed. The problem is, I can’t get the module. This needs to be fixed
Abs module
Dashboard ABS and Traction Control Lights come on intermittently with message to service breaking system. The lights are accompanied by loud audio alarms. The audio alarms usually cycle through a minimum of three times; sometime five. The dashboard ABS and Traction lights reset by themselves. Scanner codes identify an electrical problem with the ABS HCU and/or hydraulic pump. Dealership maintenance and service departments advise new parts are not available but to check back frequently for supply updates. If/when repair parts become available, this repair will be the second time I have endured this problem. Also, I have been able to reset the above dashboard alerts and audio alarms without the aid of Bidirectional scanner by cycling my windows down and up. So, I’m not sure if I have an ABS/TC problem or a wiring problem.
Keeping getting ABS warning light and electronic braking system warning.
Antilock Brake light C0020-01 DTC
Service ABS System goes on and off at various times causes cruise control not to work as designed.
ABS/HCU intermittent warning lights/ alarm on dash. Renders ABS brakes inoperable at only 25000 miles
At around 50,000 miles my truck began to turn off cruise control while driving, ding, and the ABS ,as well as, the traction control light came on. It goes on and off repeatedly while driving. This is incredibly distracting and quite possibly dangerous for braking and handling. The local dealership is aware and have stated that even though it is still under warranty, there is no available part to fix it.
On August 18th, 2022, my "Service ABS system" light starting blinking on and off constantly. I took it to the dealer. They replaced the HCU unit, part of the ABS system. It was not a cheap repair. Yesterday, it starting doing it again. I have read several places that this is a known issue and lots of people are having it. Shouldn't there be a recall by RAM for this? I tow a trailer with my truck. I'm sure this is a safety issue.
ABS PUMP WENT OUT AND THE ABS AND THE TRACTION CONTROL DOES NOT WORK. WE HAVE CHNAGED THE SENSORS ON THE WHEELS. THE PART IS ON BACKORDER AND IS HARD TO GET.
The ABS/ Traction control is intermittently failing. It is aviliable for inspection. When the light comes on I have no ABS or Traction control which may cause me to lose control under certain circumstances. The dealer has and the manufacturer has confirmed the problem. The dealership was able to reproduce the issue. The component was inspected by the dealership. There are the ABS/ Traction control light that comes on the dash sometimes. I have been told that the part that needs to be replace is backordered indefinitely and the manufacturer has no idea when they will get any new ones. From what reasearch I have done it looks like they need to reengineer the parts to make them work right. Also told that this is not covered by any recalls which I think is wrong as it is a safety issue that they knew about.
ABS, service brake system, cruise control failed and no parts available to fix it.
THE ABS BRAKING SYSTEM WAS REPAIRED ONCE 3 MONTH'S AGO AND NOW I TOOK IT BACK TO DEALER AGAIN FOR THE ABS BRAKING SYSTEM NEED REPAIR AGAIN WARNING KEEPS GOING OFF BUT DEALER SAID ITS SOMETHING DIFFERENT IN ABS BRAKING SYSTEM. THE TOLD ME NOW THEABS PUMP FAILING.HYDRAULIC CONTROL UNIT NEEDS REPLACED AND ITS ON BACK ORDERED TILL 2/21/24. I TOW A 32FT., RACE CAR TRAILER AND I NEED THE ABS BRAKES TO WORK. THESE TRUCKS ARE EXPENSIVE TO BUY THIS IS A SAFETY ISSUE.
The ABS Brake control module malfunctioned causing several electrical issues. Fortunately the vehicle was able to function. RAM Service center noted a wait time of over 3 months. When I brought the vehicle to another Service center looking to see if the part was available, I was told to make an appointment and they charged me $90 to tell me what I told them. Uggg.
Hydraulic Control Unit controlling the anti-lock brake system failed under warranty. Replaced unit by Dealer. Unit failed again after warranty expired. Now a constant alert stating "service anti - lock brake system" is displayed on the dash. Due to the expense involved I cannot have this fixed. The truck has only 21,000 miles on it. Dealer should repair. No accidents involved but no anti-lock brakes. Truck is a 2018 model.
The brake Brake HCU pump failed at 33,489 miles and was replaced under warranty last year. Now with 45,000 miles I have the same problems occurring and will have to go to the dealer again. The traction control, ABS and cruise control all do not work and the service electronic brakes message flashes on and off. The problem is intermittent. I've read online that the replacement parts are unavailable from the dealer or on a 6-8 month lead time. It seems this is a fairly common failure in the 2018 3500 trucks and Ram needs to find a better fix than a part that lasts 12,000 miles after the original only lasted 33,000 miles.
ABS and traction control lights come on intermittently and a chime sound occurs. When this happens cruise control stops working. Getting a “Service Electronic Braking System” message and “Service Antilock Brake System” message. Had to wait three weeks to get an appointment for dealer to troubleshoot. Dealer said it has code C0020-01 logged. Dealer says the Hydraulic Control Unit (HCU) has an internal failure that is shorting out the ABS pump control. Dealer stated that part will not be available until February or March of 2024 if not later for repairs. Dealer verbally said to either park the vehicle until part is available or drive it knowing that the ABS braking system may not work properly in case of emergency stop. Dealer said there is no recall for this problem but they are aware of many vehicles with it. I feel there needs to be an immediate recall issued for this problem as it is endangering the public.
My ABS and Traction control warning lights and Chime continue to come on and off while driving. Replaced the anti brake Hydraulic Brake Controller two years ago and now the same problem. I read that there are quite a few of the same model trucks having the same problem!
My 2018 3500 Dully with 34,000 miles started having an issue with the ABS, Traction Control and Eletronic Brack control systems. While driving the truck on a trip, the Traction Control, and ABS lights started coming on intermittently and the check Eletronic Brack control came on at the same time and it too flashed intermittently. Also, while this is happening, the cruise control does not work. Took the truck to the dealer, parts are not available until February of 2024. Five months from now. They recommend two parts be replaced, Anti-lock brake system, part number 68347098AB and Control Anti-Lock Brake System Part 68143491AB. I'm being told it will cost around $2,000 for the repairs. The 5-year 100,000 drive train is within the warranty period; however, this is not covered by RAM. For such an expensive truck, I find it disturbing that in the event of such failure It was advised to take the truck into the dealer as soon as possible because the truck with an ABS issue is not drivable and the dealer says its ok to drive it even though all the systems lights are flashing intermittently.
Warning light flashes ABS needs service. It intermittently goes on and off. When it does start to flash it shuts off the cruise control. The ECU also comes on/off. In 2020 Driving in the mountains when it was raining having the cruise control shutting off almost caused an accident. Braking in the rain is also dangerous if the ABS goes out. The truck now has 42,000 miles and we need to have it replaced again This makes this truck very dangerous to drive.
The contact owns a 2018 Ram 3500. The contact stated while driving 40-45 MPH, the ABS warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that ABS pump control had failed and needed to be replaced; however, the parts were not available. The dealer informed the contact that the parts would be available within 4-6 months. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 33,500.
The contact owns a 2018 Ram 3500. The contact stated that the brake failure and traction control malfunction warning lights were illuminated. The contact took the vehicle to the dealer and the ABS system was replaced. The contact stated that after the repair was completed, whenever the contact depressed the brake pedal, the pedal was spongy. The ABS and traction control warning lights were again illuminated. The contact stated that a certified mechanic diagnosed the vehicle and determined that the hydraulic control unit had failed and needed to be replaced. The local dealer was notified of the failure but was unable to repair the vehicle due to the parts not being available. The manufacturer was not made aware of the failure. The approximate failure mileage was 15,000.
My 2018 truck since owning has had 4+ of the ABS Hydraulic Control Units replaced. None of them last more than 1 year, sometimes 2 years before the ABS HCU fails again. Dodge / RAM does not offer a solution of any kind. Other than it's a know issue and parts are back ordered. Considering the part never lasts there must be another issue, Dodge/RAM needs to fix this. Thank You
I had my ABS module/HCU changed a few years ago, now I am getting the same issues and will need it replaced again. This malfunction also cause cruise control to be inoperable. This time on my dime. After research this has been an ongoing issue with ram trucks since atleast the 2018 model year. Why has a mandatory recall not been called?
At 6000 miles the hydraulic control unit and and ABS module went bad, at 15000 miles the same thing happened again
The contact owns a 2018 Ram 3500. The contact stated that the ABS system had failed to operate as needed. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the hydraulic control unit (HCU) needed to be replaced. The vehicle was not repaired due to the part being on back order. The contact was informed that the part would be available in March 2024. The manufacturer had not been made aware of the failure. The approximate failure mileage was 65,000.
ABS and traction control warning, flashing and audible alarm sounding. ABS braking system disabled. Loss of cruise control. Dealer confirms that this is a known problem with 2017/18 2500/3500 Ram pickups. Stared at around 31800 miles. Problem is ongoing, and not resolved. Dealer said parts are on nationwide back up. And not covered under warranty. See a California Class Action lawsuit for this problem.
At 26075 miles 9/10/2020, got error saying service electronic braking system. Dealer diagnosis code C0020-1was HCU (hydraulic control unit) failed; replaced unit part number 68143491AA. Problem solved. At 34412 miles 5/31/22, got same error stating to service electronic braking system. Dealer diagnosed code C0020-1, HCU failed. They replaced part number 68143491AA, again problem solved. At 40,125 miles, 8/30/2023 same error message. I will be taking to dealer, but parts are not available until February 2024 or later. When this unit fails, ABS is disabled, as well as trailer braking and cruise control. This creates a serious danger as the truck is capable of towing a load in excess of 17000 lbs. using the same part that appears to have an issue is not the solution.
ABS and HCU modules are not operating properly. Resulting in no abs and no cruise control.
HCU failure at 75k miles causing loss of ABS, Traction Control, and cruise control functions brakes are not as efficient anymore part is 8-12month back order, fiat Chrysler dealership locally said nothing we can do don't drive it wait for $700 part to come In some time in the future. Only vechicle I have I. Self employed can not just park truck for 8-12 months and continue to make payments, there is no option to sell as someone will not buy with abs issues and traction control in-op. This is a wide know issue on rams fiat Chrysler has done nothing to ensure the safety of its drivers and owners. For them to simply say park it do not drive wait 8-12 months to be fixed is absolutely ridclious. A reca needs to be issued and part failures need to be handled. Quick search on line shows many trucks having same problem and same results at dealership.
ABS/HCU intermittent failure resulting in loss of traction control, ABS function, cruise control. The risk associated to myself and others is the loss of ABS and traction control, in bad weather (rain, snow sleet) conditions the drivability of the vehicle is severely compromised. I was made aware of the open class action suite regarding this flaw and have not left the truck for dealer service. Warning lights include ABS, traction control, and service electronic breaking.
ABS Light and Traction Control Light are both on. Loss of ABS functionality. The code displayed is C0020-01. The dealer has not looked at this vehicle yet but service will be scheduled with them.
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.
