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)

Dash light illuminated with codes relating to ABS pump and traction control.

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 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 system lights flashing, and other alarms show up. Have been told by the dealer the ABS system will not work when lights are flashing, but standard braking will work. This affects the cruise control system and trailer brakes will not work when the system is flashing. Can not use this vehicle to pull my trailer. This is a true safety issue and is causing a loss of revenue. To just tell the public you don't when good parts will be available to fix the issue in not excusable. Dodge / Ram should have to buy the truck back if they can't fix it.

ABS module has been replaced twice on this truck. The latest was two weeks ago. However the problem of service ABS and service electronic braking messages still appear randomly, killing the cruise control and dinging. The dealership who took 2 months to get the ABS module this time stated that the Hydraulic Control Module was now bad and back ordered forever so I will have to live with it, apparently forever by the sound of it. So now I’m cruising around in a 15k lb bucket truck with no sign of getting it repaired in sight without buying another for 150k.
