Recall on anti lock brake system been on wait list for over a year and Ram is not even attempting to fix my truck I have called and talk to Jessica with Ram back in October of 2025 was told part would be available in February of 2026 still no part I have no cruise control and my auto start won’t work with the lights on the dash I don’t know what else to do I just want my truck fixed
Subject: Safety Recall Remedy Unavailable Due to Lack of Parts I am submitting this complaint regarding my Ram truck, VIN [XXX], which is subject to a Stellantis safety recall involving the C4B Hydraulic Control Unit (HCU). Although Stellantis has acknowledged this as a safety-related defect and issued a recall, I have been unable to obtain the required repair because replacement parts are not available. After multiple attempts of inquiring for a repair, my dealership has informed me that there is no estimated date when the hydraulic control unit will be available. This situation leaves me with a vehicle that is subject to an unresolved safety recall, yet neither the manufacturer nor the dealer can provide the required remedy within a reasonable timeframe. The recall involves a critical braking system component that affects the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and Traction Control System. These are essential safety systems designed to help maintain vehicle control during emergency braking and adverse driving conditions. I tow a 16K lb fifth wheel and the risk is unacceptable for the past 18 months-not to mention the constant dinging of the warning, light, inability to use cruise control, and the inability to trade in or sell the vehicle. I am concerned that Stellantis has initiated this recall without ensuring that an adequate supply of replacement parts is available to promptly repair affected vehicles. Owners are left waiting indefinitely while continuing to own and, in many cases, operate vehicles with an acknowledged safety defect. I respectfully request that NHTSA investigate whether Stellantis is meeting its obligations under federal recall requirements by providing an effective and timely remedy. I also request that NHTSA require Stellantis to improve parts availability and communication with affected owners so that recalled vehicles can be repaired within a reasonable period. Thanks.

The HCU ABS is malfunctioning causing the cruise control to not work along with anti lock brake functions. This could cause a brake malfunction leading to a crash. We have received the recall notice, C4B/NHTSA 24V-896 over a year ago. We have contacted the local dealer several times during that year, including May 21, 2026. No effort has been made by the dealer to change the defective part and we have been told no parts are available and no delivery date can be given to change the part. Meanwhile we are forced to drive a vehicle with the potential to cause a crash. Please take action to help us.
The issue involves the ABS (Anti-lock Braking System) and hydraulic control unit on our 2017 Ram 3500. The recall states that the ABS module/hydraulic control unit may fail, which can impact braking performance and disable safety systems. The component has not been repaired because parts have been unavailable for over three years. The vehicle is available for inspection upon request. This defect creates a serious safety risk. The vehicle is primarily used to tow livestock, including horses, and loss or reduction of braking capability while towing could result in loss of control, increased stopping distance, or an accident involving occupants, other drivers, or transported animals. The problem has been confirmed by authorized Ram dealerships in Chehalis, Washington and Eureka, California. Both dealerships, as well as Ram customer care, have acknowledged the open recall and stated that no parts are available to complete the repair. The vehicle has not been physically inspected by the manufacturer for repair because no remedy has been available. It has not been involved in an accident related to this issue. Prior to the recall, there were no known warning messages or confirmed failures observed. However, the recall itself indicates a potential failure of the ABS system and braking components, which may occur without warning. The recall has remained unresolved for an unreasonable amount of time. The manufacturer has failed to provide a remedy for this safety-related defect within a reasonable time.
My ABS hydraulic control unit pump motor is not working properly. This has been affecting me since Oct 2024 when we were pulling our 5th wheel and losing braking and power. I learned later that It is part of a NHTSA Recall 24V-896000. Code C4B I was told by the Dodge dealer Jack Powell in [XXX] that I was on waitlist when I reported it to them 12/19/2024. During the next several months I always got the same answer so then filed a case on 7/7/2025 with the FCA. Case #XXX. During many calls after, and including the last call on 3/27/26 that the part was not available, that this was a National backorder with no ETA. I filed another case on 8/17/25 for a rental vehicle - case #XXX. After several calls I got that approved. The Dodge dealer diagnosed my truck with that active code in place. Also to be clear, the dealer has confirmed failure of the ABS system, which disables safety features Due to this defect, the truck can lose ABS braking, tractional control and electronic stability control. The dash warning lights come on all the time, with the sound too. Although I was approved for a rental vehicle, that is for $60 per day and only for a non-tow vehicle. The problem is that this vehicle is primarily used for towing. I have a 5th wheel hitch and use it for towing our 5th wheel trailer, that we purchase early 2024. We tow our boat as well. The bigger problem is that I am near retirement and we are not able to use our 5th wheel for the trips to prepare for that and the plan to travel once I retire later this year. I need to have a functionally comparable vehicle that is equipped for 5th wheel towing as a rental or reimbursement. I would also like a review for alternative remedies due to the unreasonable delay in completing the safety recall. When I contacted Stellantis on 3/27/26 I was told her was no buyback option and they would escalate to the rental dept for my concerns The vehicle is available for inspection upon request.

While driving on interstate 20 and then on I65 my cruise control dropped off causing the vehicle to sudden decrease in speed. Rear end collision narrow avoided due to commercial vehicles, following, quick action saved a disaster. This loss of cruise control, is/was caused by the warning ⚠️ of recall C4B/NHTSA 24V-896. We are now experiencing a total loss of safety (service electronic brake system, service abs system, loss of traction control, {loss of cruise control}). These safety functions are now making this, one ton, dually, a death trap, mental health problem (I have PTSD, depression, anger management, anxiety problems) . My wife is afraid of this vehicle, WILL NOT let me pull our 42 foot, 15,000 pound, Redwood 38GK 5th wheel RV. Should your investigation be done, this is the 3rd recall/repair on this system.

I've been driving it since then with no anti lock brakes, traction control, and no cruise control. This seems unsafe to me and all other drivers. I have contacted the dealership and there is still no remedy for the issue. Please consider this a formal complaint. Thank you.

The ABS module has not worked for over a year. To me this isn’t a timely response. What are my options?
