ABS/HCU intermittent warning lights/ alarm on dash. Renders ABS brakes inoperable at only 25000 miles

- Mount Airy, MD, USA

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.

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, service brake system, cruise control failed and no parts available to fix it.

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.

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.

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.

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 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

At 6000 miles the hydraulic control unit and and ABS module went bad, at 15000 miles the same thing happened again

- Wilmington, DE, USA

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?

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.

ABS and HCU modules are not operating properly. Resulting in no abs and no cruise control.

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.

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.
