recall C4B hydraulic control unit still not addressed as of may 7 2026 recall received on

Ref NHTSA 24v-896, Recall C4B The problem started back in 2021 when the anti-lock brake Hydraulic Control Unit failed. It was replaces and then it failed again in Dec 2024 while on vacation. When returning home in Jan 2025, the truck was brought to the dealer for repair. It was found to have failed again and told that a repair parts were not available, nor was it known when the redesigned part would be available. Shortly after that I received a letter stating that my truck was included and confirmed to be part of this recall. I have been severely impacted (restricted use of) due to safety concerns when driving this truck. I've not been able to get any assistance from Ram dealership or Ram customer service. What can be done to resolve this issue with RAM? Thanks for you assistance! [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My ABS pump went out, causing my stability control to not function and cruise control to not function. Cruise control would randomly deactivate, causing a momentary loss of control and ABS function. Dash light illuminated with codes relating to ABS pump and traction control. ABS pump was replaced (part no. 68195569AB) and problem was fixed, but FCA will not reimburse me since I did the work myself.

The contact owns a 2018 Ram 5500. The contact stated that while driving at various speeds, the ABS and Traction Control Service warning lights illuminated. Additionally, the contact stated that the cruise control failed to operate once the warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a defective ABS module. The contact was informed that the ABS module needed to be replaced. The mechanic called an unstated dealer and was informed that parts for the repair were unavailable and that there was no ETA on when parts would be available. The manufacturer was not notified of the failure. The failure mileage was approximately 93,000.

The ABS module has failed. This has caused the service ABS light to come one, the service electronic braking system to come one, and the service electronic throttle control light to come on. The module according to Chrysler is part number 68347099AC which is unavailable at any dealer in the country. We have called many dealers and they have searched for the part to no avail. We have contact Mopar corporate and they told us there is no update on this part. We feel that operating the vehicle is unsafe but we don't know what to do without the part. Chrysler has offered no assistance. I have attached photos of the check engine lights as well as a photo from the scan tool showing the failure of the module - it cannot communicate.

The contact owns a 2018 Ram 5500. The contact stated that on several occasions while driving 60 MPH with the cruise control activated, the ABS warning light and the Traction Control Service message was displayed with an audible pinging sound intermittently. Additionally, after the message and audible ping, the cruise control message was displayed. The vehicle was taken to a dealer where it was diagnosed that the ABS/HCU module needed to be replaced. The vehicle was repaired but the failure reoccurred. The manufacturer was notified of the failure. The failure mileage was 11,870. The contact stated the dashboard alarm (ping) alerting the driver of loss of traction control on the dashboard pinged no less than 300 times in the 1168 mile trip.

The ABS/HCU module has experienced a premature failure which is a huge safety risk as it controls my vehicles' Anti-lock Braking System, Traction Control & Cruise Control systems. Since experiencing this failure, my vehicle has had numerous safety incidents where Braking would lockup, traction with the roadway is lost etc. Please initiate a recall for this issue for these generation of trucks so this safety issue can be addressed.

Twice in the past year I have experienced a loss of the ABS braking system. Warning messages appear to service the ABS braking system as well as a general braking system malfunction. This loss of ABS is intermittent. I have taken it to the dealer to have it fixed both times, and they have replace the hydraulic control unit and ABS module. Mechanic told me this is a very common problem with these trucks. I was put at risk by not having a functioning ABS.

Abs/Hcs module failed causing intermittent braking issues along with intermittent warning light. Had to replace both the pump and module to resolve the issue. Over $1500 in repair.
