2018 RAM 3500 Complaints

ABS and traction control lights activate and error message states to service electronic braking system. No ABS functions as a result. Dealership diagnosed problem as the ABS HCU(hydraulic control unit). Issue can not be corrected due to unavailability of parts. This is a safety issue that should be recalled as it is a known problem by the manufacturer.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the brakes inadvertently engaged. The traction control warning light was illuminated, and the Service Electronic Braking System message was displayed. The vehicle was taken to the dealer, where it was diagnosed that the HCU needed to be replaced; however, the replacement part would be on backorder until March 2023. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 37,353.

The contact owns a 2018 Ram 3500. The contact stated that while driving at various speeds, the "Service ABS" warning message and ABS warning light were illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the ABS hydraulic unit needed to be replaced; however, the part for the repair was not available. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 25,000.

ABS and Traction Control lights stay on due to the HCU (Hydraulic Control Module) failure, a known problem reported from the garage. I've been waiting for a replacement part for 6 months. I was told to check back in the middle of March 2023.

While driving on a paved 4-lane road near Mount Rushmore National Memorial in dry conditions, the dash warning system began intermittently flashing "Service Electronic Braking System". The orange ABS and traction control lights also began flashing. The foregoing visual warnings were accompanied by an intermittently ringing audio warning. Retrieval of error codes from the ABS control system with a INNOVA 5610 scan tool showed: DTC CODE C-0020-01 - ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. This code relates to failure of the ABS Hydraulic Control Unit (HCU) and indicates that repair requires replacing the failed HCU with part 68143491AB (replaces part 68143491AA HCU). (SEE Fiat-Chrysler Automobiles STAR Online Publication case number S2005000004. This STAR Online publication (released on 4/28/22020) further states that if replacing the HCU does not solve the failure, the ABS control module may require replacing as well.)

ABS and Traction Warning lights illuminate, and go out, repeatedly. Dealership diagnosis indicates that the ABS Hydraulic Control Unit needs to be replaced. ABS is not functioning. Initial estimate for repair was two months, but has been updated to four months as of today (January 27, 2023).

Abs hydrolic module out again for second time ealerships has no parts tells me not safe to drive. Told me they have 12 vehicles with same issue waiting for parts???? This needs to be a recall. These trucks cost to much h for ongoing issues over same parts.

Intermittent loss of breaking performance. Constant on off error saying service ABS and service electronic brake controller. This also effects traction control. This goes on and off several times per minute. When the warning comes on, it also disengages the cruise control if set. I carried it to the dealer, and they ran a scan, told me it was the hydraulic control unit (HCU) and the anti-lock braking system (ABS) module. They said the part was on backorder, so I guess I am stuck with driving a vehicle that is unsafe, as it has ABS and traction control issues, and no part in stock to fix it. This is wonderful news for such an expensive and robust vehicle. Nice to know that a very heavy truck pulling a trailer with a load on it no longer has working safety features for the brakes and traction control. There seriously needs to be a recall on this issue as safety is at the heart of the problem, and these trucks still have to work daily as they were designed to do. It appears there may be a recent class action lawsuit on point in the state of Texas only. It would be a much better solution if a recall was initiated heading off multiple state class action lawsuits that do not fix the problem but simply make the attorney's rich. These issues need fixed, not just a small check for compensation to the truck owner who will then likely never fix it. I feel time is of the essence.

It seems to be a very well known issue with the antilock brake control module and it affects the traction control, cruise control, and disables the trailer braking system which is extremely important, I tried to make an appointment with my local dealer and they knew exactly what I was concerned with and I was told that the part is back ordered and may take a month or two to get the part needed to make the repair. This should most definitely be a safety recall, I have several different trailers that I pull that if I had not known of the trailer braking issue with the module not working correctly it would have been a nightmare in certain circumstances

1. ABS pump failure, stable tract for steering. Available for inspection if requested. When this warning light comes on cruise control will not function. 2. If ABS failure cannot slow down in a timely manner danger to occupants. 3. Yes 4. Unknown 5. Yes, warning lamps appeared at 15,000 miles. Would like to see this be a recall because numerous other owners have this same issue.
