2018 RAM 3500 Driver assistance Problems

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.

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.

My vehicle is included in safety recall 24V-896 for a defective HCU (Hydraulic Control Unit). I have contacted the dealership multiple times, but the replacement part is never available. This recall affects critical safety systems including ABS and Electronic Stability Control. Despite being a safety recall, there is no estimated timeline for repair due to part unavailability. I am concerned about driving a vehicle with an unresolved safety defect. The manufacturer has been unable to provide the recall repair for an extended period.

There is an open recall (C4B) for my Ram truck. The ABS light and "Service Brake System" light and message are currently displayed on the truck's dash. I contacted FCA about a year ago and told them I have an active issue. They said they placed me on a priority wait list but the remedy is not available yet. It is unacceptable for them to not have a remedy ready for an 8 year old truck when the issue was known about some time ago. I would appreciate if NHTSA or other government agencies would put pressure on FCA to repair this issue as owner's and other motorists lives are on the line if faulty equipment is forced to drive on public roadways. Thank you

Since January 2023, my truck stability control system has been disabled related to CB4 NHTSA 24V-896 recall. TWO years! I can't sell the truck like this & I have no idea when it will result in an accident. Stellantis needs to be held accountable. Every contact with them results in a response of waiting for parts. I've had no choice but to drive another 18000 dangrous miles with this vehicle. This is unacceptable.

Almost got into a wreck because my ABS failed. I was going down the interstate with my cruise control on and my abs and traction light came on. My cruise control.immediately stopped working and I was almost rear ended. I called the Ram dealership and they said they have no time frame of when they will have parts in to fix it under the recall. Does someone have to die before Ram will start fixing these abs units. The recall has been out since Nov 2024. They need to be held accountable or buy back all 2017 and 2018 rams affected by this.

Traction control and ABS work intermittently. Ram sent out this notification for recall concerning stated problems but state there is no fix at this time. They continue to state there is no fix. This is a safety issue and you are not forcing them to repair. They are dragging their feet hoping it goes away. DO SOMETHING!!!!

The Hydraulic brake control has been a recall with no replacement part available for over 2 years and this causes many safety functions to not work properly including trailer braking. They have made parts for a 2500 model but neglected to fix the 3500, 4500 and 5500 models. They will fix it with another faulty sensor and still expect owner to pay a 1700 repair bill even though it’s a recall. It’s ridiculous on the time this is taking.

24V-896. This recall is a safety issue known for years. There is still no action from the manufacturer! I was extremely lucky to avoid a serious collision. The only solution the manufacturer offers is to authorize a dealer to replace the parts with another secondary market provider part, but they won’t cover the cost or warrant the replacement. How many YEARS do I have to drive an unsafe vehicle?!!!

I have not been involved in an accident yet. You can’t drive the truck because the warning goes every 2 minutes. The brake hydraulic control unit has failed and they will not fix the truck. I can’t pull my camper. I have at least 6 hours on the phone with Ram and they say there is nothing they can do. The dealer ship says they have the part that is on the truck now, but Ram will not allow them to install it. It’s not the new part. Mean while my truck is useless until they fix it. They have been aware of this issue since 2017 and they still do not have a replacement part. The right thing for them to do is put the they have on hand on it so I can a least drive the truck. The truck has 90k miles on it. The vin # [XXX] . My contact info is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This recall notice, was first identified in September or October, with the Official Communication issued in November of 2024. How long am I, or anyone expected to endure the nuances of this recall. We are well beyond 6 months now with no remedy, and it does not appear as if RAM\Stellantis is concerned with a fix. They've sent a disclaimer notice, but what is the resolve to a vehicle I purchased and continue to make a monthly payment towards - but you are basically telling me don't drive. Alternatively, dealership service advisors call me every six weeks to come in for a diagnostic ( not free of course ) only to say well it is related to the HCU so there isn't anything we can do right now. When\If I drive my vehicle I have to listen to a buckle your seatbelt type of alarm the entire drive. Its not only mind numbing its traumatic. Will Stellantis or Ram be forced to compensate me money I've paid monthly for a vehicle I technically can't use or shouldn't use? My complaint is to determine when this problem will be fixed and what is the NHTSA is doing to ensure my rights are protected as a consumer and what they are doing to push this manufacturer to fix this safety related issue.

Related to the known HCU failure on these vehicles. My first submitted complaint was on Oct 22, 2022 and this issue is still not resolved. I received a letter in mail on January 21st of this year stating that a recall was finally underway. Now it's late March and everyone's standard response is "No Remedy Yet". The remedy is actually installing HCU part number 68143491AB which replaces the corrupt factory installed part 6814391AA. These parts are readily available online so why can't factory service centers begin replacing these failed HCU's. This complaint is filed due to my belief that this dangerous safety issue is not being resolved in a reasonable, timely manner. Not even close.

I had the ABS recall repaired 3 years ago when Ram was refusing to acknowledge this as a defective product. I paid for this repair. Under the recall I'm elgiible for reimbursement but the company is refusing to reimburse me for the repair after I sent them an invoice showing proof of work and my payment. This can't stand. Please force them to issue a refund for the $100 I am owed.
