I am the owner of a 2018 Ram 3500 subject to Recall C4B (the federal safety agency Recall No. 24V‑896) involving the Brake Hydraulic Control Unit (HCU). The recall was announced on November 27, 2024. As of June 2026, the federal safety agency’s website still states that the recall is incomplete and that a remedy is not yet available for my vehicle. The defect causes active symptoms during operation. The vehicle continuously chimes while driving, similar to a seatbelt warning, and cruise control is disabled. These symptoms substantially interfere with normal operation, especially during long trips and towing. I have contacted authorized Ram dealerships and Ram Customer Care multiple times. Dealerships state that no remedy is available and refer me to Ram Customer Care. Ram Customer Care confirms that no remedy is available and provides no repair timeline or meaningful resolution. Most concerning, neither the dealerships nor Ram Customer Care will initiate a repair attempt because no repair procedure or parts exist. Owners are therefore unable to obtain repairs or even establish documented repair attempts despite the existence of an active safety recall. I was also advised that I could rent a vehicle at my own expense and potentially seek reimbursement if approved. Given that this recall has been open for more than 18 months with no available remedy or repair timeline, expecting owners to personally fund rental costs for an unknown period with only the possibility of reimbursement is unrealistic and inadequate. This open safety recall has negatively impacted the vehicle’s usability, resale value, and trade-in value while preventing owners from obtaining a repair. Stellantis acknowledges the safety defect, yet no practical remedy or alternative solution is available. I respectfully request that the federal safety agency review the continued lack of an available remedy, the extended delay in repairs, and the absence of a meaningful process for affected owners to obtain relief.

Several years of ABS check light illuminated. No ABS, no cruise control. Started intermittently then became permanent. Diesel shop diagnosed defective HCU/ABS module. Local RAM dealer parts department doesn’t have parts for years - “ indefinite back order”, they say.

There is still no remedy to this recall and my truck is affected - I have been driving with NO ABS AND NO TRACTION CONTROL for almost 4 YEARS. This has also deactivated my cruise control. This is unacceptable and compromises me and my families safety. This is not a question of if it is going to happen, but when. My vehicle isn't under the category of "may be susceptible to failure" it has failed and I have permanently lost those BASIC and CRITICAL safety features. It is simply a matter of WHEN the lack of those features will cause an accident. There must be something done. . I have spoken with Mopar and several dealerships and nobody has given me any solution other than to say they will call me when a remedy is available. That is NOT ENOUGH. Recall language for C4B "The brake hydraulic control unit (HCU) on your vehicle [1] may be 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/ESC/Traction control progressing to permanent loss. The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning. "

I am getting an error concerning the antilock brakes on my truck. This error is random shows up every few days. When it does show up it dings every thirty seconds and does not stop, which is very distracting. Also shuts off the cruise control. It took a copy of the recall to my local dodge dealer and they will not fix it.

RAM recall dates December 2024 on ABS failure. Received letter a long time ago. However, RAM still says parts are unavailable and it's been 18 months. This is ridiculous. Failure includes Cruise Control turned off. Audible sounds and warning lights on Dash.

It has been 3 years of our ABS failing due to a Brake HCU not being replaced. Now the engine light comes on due to issues with the Electronic Braking System. We cannot use this to travel due to the cruise control going out as soon as the ABS light goes on which is every 5 minutes. Why is this allowed to be on recall but ‘ no fix has been determined’?!!!! We need answers.
