My ABS alarms constantly as I drive. This issue started in September 2024. I cannot use my truck as desired because of constant alarming making traveling, as the truck was purchased for, impossible to enjoy for us. I have contacted my dealership approximately twenty times about repairing. I have been given multiple answers but have received no help. I have contacted customer care, customer service departments at Stellantis/Mopar five times and basically have been given the same answer, we are working on a repair. Please get Stellantis/Mopar/Ram to help customers. Manufacturer Recall Number-C4B NHTSA Recall Number-24V-896 Recall Status Recall: Incomplete, remedy not yet available

Received Important Safety Recall notice, Hydraulic Control Unit (HCU) ABS, C4B/NHTSA 24V-896 more than 2 years ago. To date, nothing has been done and I'm scared to drive it for safety reasons. There is a very annoying alarm dinging most of the time. I have phoned several times asking when the recall can be performed. Every time the answer is parts are not available yet. For our safety, we would like the parts available and the recall performed very soon.

NHTSA Recall #: 24V-896 Dogde Recall #: C4B Dodge Part #: 68143491AB HCU My complaint is because the I have tried to get this recall done a two separate dealers and it can't be done. Both service departments have told me the same things, the part # that is supposed to be the recall item has been taken out of inventory and the dealer can't get the part. This I believe happened in 2024. There is no current inventory part number to handle the HCU recall putting my vehicle in limbo. The dealer said this isn't the first experience with the problem. My truck has 15k original miles and I have ABS and Brake warnings flashing at me and 2 dealerships have confirmed that there is no current replacement part to order to do the recall.

Before the recall, I was driving my vehicle and the brakes and the power steering locked up. The vehicle felt like it was trying to drive with the emergency brake on. After this happened, I took the vehicle to Haley Jeep Jam, Richmond, VA, and they said they couldn't determine anything was wrong, but replaced the brake pads. Shortly after this visit to the service department, the recall appeared. Since the recall, we have contacted Haley Jeep Ram and Whitten Brothers multiple times, but they are unable to fix the recall due to no resolution from Daimler Chrysler. In August 2025, Whitten Brothers, Ashland, VA, replaced the part with a new, recalled part as a temporary fix. There is still no permanent fix for this recall which continues to be a safety risk. Since the vehicle has an outstanding safety recall, we are unable to sell or trade in this vehicle. We have been patiently waiting but believe this should no longer be our problem. Daimler Chrysler needs to do the right thing to assist the vehicle owners. We have mailed a corresponding letter to NHTSA. Thank you for your time.

Waiting over 18 months for recall repairs to be made. My truck will not pass the mandatory state safety inspection because the ABS lights in the dash board display. This makes me operating the truck illegal and subject to a violation. Called manufacturer numerous times to complain yet they take no action.

I am the owner of a 2018 Ram 3500 subject to Recall C4B (NHTSA Recall No. 24V-896) involving the Brake Hydraulic Control Unit (HCU). The recall was announced on November 27, 2024. As of June 2026, NHTSA’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 NHTSA 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.
