2018 Ram 2500 Complaint Log

A recall notice was issued on November 27, 2024, regarding a faulty hydraulic brake control unit (HBU) in my 2018 Ram 2500. It has now been over a year since the recall was announced, and there is still no remedy available to replace the unit. Currently, both the ABS and Traction Control service lights are illuminated on the dashboard. When I contacted my service department, I was informed that no action can be taken until an official remedy is established. Could you please advise how much longer owners should expect to wait for this issue to be resolved? Given that more than a year has passed since the recall was issued, I would have expected a corrective solution to be available by now. Thank you for your time and assistance.

Why, after more than 5 months of a recall issuance, is there still not a "fix" issued to service dealers to make needed replacement of the Hydraulic Control Unit ABS (recall C4B)? Is anybody overseeing this matter to ensure timely resolve to this safety issue? I called my local Dodge dealer this morning to check on this after not hearing any further word about it despite registering my vehicle for recall notification with Fiat Chrysler Automobiles, and learned that they have a bulk shipment of 16 HCU units in stock, but they do not have the vehicle computer programming (or something to that effect) to initiate fixing the matter. I sure hope the HCU on my truck doesn't fail and cause an accident.

Had my abs replaced once already with around 20k now has 57k and my light is back on

I do not feel this recall - considering it is regarding BRAKES - has been remedied in a timely fashion. It started over a year ago. They obviously are not interested in addressing the fix. I assume they are taking the hit and paying off lawsuits as it is cheaper than actually completing the recall. But whatever the reason, they have not addressed this and my RAM repair location keeps telling me "parts are not available" to fix it. A recall was issued but it does not appear it has any teeth. What is the point? Please let me know if any action is imminent. It can also potentially effect the transfer of title if I chose to sell the vehicle. Thank you for your attention to this matter.

The recall was issued in November 2024 and it been almost a year and the part is still not available yet.

The local dealer was called and confirmed that the parts were on back order. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The contact had not experienced a failure.

ABS warning keeps flashing intermittently. The HCU module apparently has issues. Took vehicle back for another recall issue and they told me to watch it and if I pulled trailers to bring it in. Apparently, dealers are aware this is an issue and research showed me that a recall Is possible so I am reporting the issue.

The contact owns a 2018 Ram 2500. The contact stated while driving approximately 25 MPH, the ABS warning light intermittently illuminated.

CB4 Recall Some (2017-2018 MY Ram xxx) vehicles may have been built with a brake hydraulic control unit ("HCU") that is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss. Been dealing with this issue since the recall got initiated back in November 2024. I call Mopar every month to check on the status and still no parts available. I haven't had any brake failures in my truck or scares, but whoever has this issue has to understand how annoying the constant chime is. Can't use cruise control and worst thing is if you are considering selling your truck outside of a Ram dealer, they won't take it in because of the open recall and privately, who would really consider buying a truck with this issue. My fear is that Mopar (Stellantis) is just putting this in the backburner with no plans on fixing it.

My vehicle has had the Service Electronic Braking System/Service Antilock Braking System warnings appearing for approximately 6 months, along with the ABS light and Traction Control light being illuminated. It was intermittent at first but has been on steady for the past month. The vehicle has not been to the manufacturer to get inspected yet due to the intermittent nature at first. With the lights being illuminated, I have had a time or two where when the brakes were applied in a quick manner, the abs was not engaged and the tire locked up when a deer ran across the road.

I'VE BEEN OPERATING MY TRUCK SEVERAL TIMES NOW WHERE THE CRUISE CONTROL HAS WENT OFF OR DISENGAGED WHILE DRIVING, CAUSING A SLIGHT PANIC FROM NOT KNOWING WHAT WAS GOING ON IN THAT MOMENT. THIS HAS ALSO HAPPENED WHILE TOWING, WHICH MADE THINGS EVEN WORSE. MY CRUISE CONTROL IS NO LONGER WORKING AND NOW I AM DEALING WITH THE RECALL WHERE THERE IS A "REMEDY NOT YET AVAILABLE". THIS WOULD BE RECALL MANUFACTURER NUMBER C4B AND NHTSA RECALL NUMBER 24V-896. I BELIEVE THIS RECALL TO BE TIED IN WITH MY CRUISE CONTROL ISSUE. NOW I HAVE A TRUCK THAT I HAVE NO OTHER OPTION THAN TO OPERATE AS MY DAILY DRIVER; WITH NO CRUISE CONTROL, ABS/ECS/TRACTION CONRTOL. I'VE CONTACTED SEVERAL DEALERS TO SEE IF THEY HAD ANY INSIGHT AND I HAVE BEEN GIVEN THE SAME ANSWER ABOUT THERE NOT BEING A 'REMEDY'. I WANT IT TO BE KNOWN FOR LEGAL PURPOSES THAT I DO NOT FEEL SAFE OPERATING MY TRUCK AT THIS TIME BUT AGAIN I HAVE NO OTHER VEHICLE AT THIS TIME TO OPERATE. I HAVE AGAIN REQUESTED ASSISTANCE FROM SEVERAL DEALERS WHO HAV BEEN UNABLE TO HELP ME WITH THE RECALL LISTED ABOVE.

ABS and Traction Control lights come on intermitenetly and loss of cruise control. Says service ABS Control System. This is a very common issue and something that could easily cause a major accident in not ideal situations if not resolved quickly. The dealership has inspected it and confirmed the ABS Module is the culprit. This is obviously something that is common and should be investigated more.

My brakes locked up due to the abs pump not working.

My trucks braking systems hydraulic control unit (HCU) is Malfunctioning. It goes in and out of service while driving and two warning lights and a buzzer will sound on and off. This part was replaced during the 3/36 warranty and again when out of warranty for two replacements before 71k miles. Now for the third time it’s malfunctioning at 111k miles. I failed to convince Ram to replace it for the third time under warranty and was denied. I was told the part and the truck is out of warranty and will be an out of pocket expense to repair. I feel the dealer installed a known faulty part and Ram should replace it with the new corrected part number at no cost.

In November 2024 through December 2025 our Ram started experiencing issues with the traction control and ABS lights coming on randomly and the vehicle not braking properly. Braking in corners is very sketchy and feels like you are going to run off the road. As December went on, all brake related lights stayed on and the truck feels like it has manual brakes from the 1970s. We received a Legal Notice explaining there is a class action settlement going on due to the ABS module and Brake HCU on our truck in late December 2024. We did not drive the truck long distances for the latter half of December due to the issues we were experiencing plus receiving the legal notice. A couple weeks into January 2025 we received a notice from FCA US LLC indicating there is a safety recall for the Brake HCU which affects the ABS and ESC systems. The notice said the vehicle may lose control and cause a crash without prior warning. Due to this second notice and the fact that our truck was having more issues with the braking systems and the lights were permanently on, we parked the truck mid January 2025 and have not driven it since. In early March we contacted the local dealership Morie's of Little Fall, MN as well as Chrylser/Mopar asking when our truck can be repaired and explained this is our daily driver and only safe vehicle we have for distances over 30 miles. Neither of them have been helpful and could not give us an answer. The service person at Morie's confirmed our vehicle is a part of the recall and the things we are experiencing would be related. He advised we do not drive the vehicle either. We are now mid April, THREE MONTHS WITHOUT A SAFE VEHICLE TO DRIVE, and we have received no further communication from anyone relating to our truck. It is still parked and unsafe to drive. Action needs to be taken to remedy this situation. We are normally a two vehicle household down to one that can't be driven far and one that can't be driven at all.

Traction Control and ABS not working properly. ABS light on dashboard is on called dealer several times and am told that the parts are unavailable.

Anti-lock brake hydraulic controller failure

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE continues to come up in my vehicle each time a bump in the road is hit. I am very concerned that this will cause intermittent or permanent loss of braking performance while driving and potentially endangering myself and other motorists. There are numerous complaints about this same issue on the internet with these model year trucks and FCA should be doing something about this inherent risk.

Abs light and traction control light stays on plus keeps popping up to service electric trailers brakes. Electric trailer brakes well not work. Cruise control stopped working. All do to recall. Truck has had this recall for over a year now and I’ll I ever get told by dealerships that the parts are unavailable. Dodge makes this junk ass trucks everyday so I don’t understand why parts are unavailable.
