This recall affects the brake hydraulic control unit ("HCU") on my RAM 2500. I already had this part replaced back in 2022, and it went bad again in the Summer of 2025. I'm trying to sell the truck, but the incessant error messages and bell ringing makes that impossible. Nobody is going to buy a truck in this condition. Ram has known about this for years, and the recall was issued 14 months ago. Still no fix? I had the truck to my dealer last week and they said they are unable to help me with a replacement part, because it is not available. So now I'm driving around with a broken ABS system and constant error messages and audible warnings from my dashboard. For such a big company, it shouldn't take this long to develop a remedy to this problem. Anything you can do to assist would be appreciated. Thanks.

CB4 Recall Some (2017-2018 MY Ram xxx) vehicles may have been built with a brake hydraulic control unit ("HCU") that is 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/Traction control progressing to permanent loss. Been dealing with this issue since the recall got initiated back in November 2024. I call Mopar every month to check on the status and still no parts available. I haven't had any brake failures in my truck or scares, but whoever has this issue has to understand how annoying the constant chime is. Can't use cruise control and worst thing is if you are considering selling your truck outside of a Ram dealer, they won't take it in because of the open recall and privately, who would really consider buying a truck with this issue. My fear is that Mopar (Stellantis) is just putting this in the backburner with no plans on fixing it.
It has been 7months since I bought my truck. STILL I have an open safety recall that hasn’t been fixed since no parts are available. I live in the Midwest and bought a ram truck just for the snow and conditions. I’ve been stuck more this winter than ever due to this abs recall. It takes away traction control, takes away cruise control. It’s not safe at all. I need this figured out IMMEDIATELY

Truck def system error derates vehicle speed to 5mph in 85 miles. This is unacceptable as no dealerships are open on weekends or in the middle of nowhere. This EPA rule will get folks killed as folks driving 5mph on freeway towing a big trailer will get run into real quick. Vehicle should NOT cause you to slow to 5mph if a pollution control device has issues. Please investigate.
ABS TRACTION CONTROL LIGHT HAS BEEN ON/OFF SINCE 2020. Can't drive on snow ice due to traction control abs 4-wheel drive doesn't work correct. I almost hit the divider/wall on Interstate 30 on 01/28/26 due from poor braking.

Dash warnings for abs / traction control flicker on and off steadily. Every time the warnings come off it kicks off cruise control. I live in often snowy conditions and I worry that steadily changing traction control systems will absolutely be dangerous. Not to mention the frustrating noises of the alerts coming on Avery few seconds. As I was told by my dealer, this recall has been out there since December of 2024. I’ve been dealing with this issue for months and it is getting worse.

This is an excessive amount of time to still not have a remedy available. Especially when RAM has remedied the same issue with the RAM 3500 Chassis.

I have had this recall for over 3 years and its still not fix. Its dangerous to drive because you will never know when the brakes goes out completely. I have call the dealership many times and I receive the same answer like they waiting on the parts to arrive.
The transmission is slipping and making clunking noises and I'm worried it fails while driving it could be a safety issue. I noticed other people online mention the same problem. This should be a manufacture recall to get repaired not a consumer.

Code C0020-01 ABS-VSC lamp and intermittent warning chime.
My VIN had the steering recall performed, but the welded drag link, which was the "remedy." At the time, it prevents alignment. The vehicle is now non-serviceable. I called Dodge requesting authorization for the updated adjustable drag link and alignment under recall remediation, and was told there is nothing they can do. This is incorrect. I called them four (4) times and was hung up on each time. Recall remedy V06 rendered the steering non-serviceable The vehicle cannot be aligned. The steering wheel cannot be centered.

I am in Virginia and received a recall code C0020-01 for general abs fault. The truck continues to beep alerting me of this fact. I need replacement of the hcu. Which i have been told controls the breaking hydraulics. To me this seems to be of concern and could easily cause an accident and injury. This has been occurring since August of 2025 and I have been in contact with the dealership, Blackwell of Danville, VA, since then. On 11/1/25 I went into the dealership for other issues but this problem as well. They told me there is no part available for replacement and hasn't been for over a year. Well we are in a new year so how much longer do I need to wait for my truck to be safe?
Abs control module defective been having this problem for over five years. Ram just keeps saying no parts available. That they are working on solution. I think they are dragging there feet on purpose hoping the trucks will wear out before they have to fix. These companies need to be held accountable. Thanks for any help

The vehicle had multiple unresolved safety defects from the time of purchase. The radio and electrical system never functioned correctly and could not be repaired despite repeated dealer visits. The stabilizer bar failed and fell out while driving, causing loss of steering stability. The vehicle is currently subject to an open federal safety recall for ABS/ESC/traction control loss with no repair remedy available. These defects created a serious crash risk and caused loss of safe use of the vehicle. The manufacturer and authorized dealer failed to repair the vehicle.

Anti lock brake control has failed twice and then afects cruise control and warning bell continues to ring paid to have fixed twice and still no factory fix .it hs been on recall list for years now!
I own a 2018 Ram 2500 equipped with the 6.7L Cummins diesel engine that I purchased brand new in Iowa. For approximately the last four to five years, my vehicle has displayed persistent warnings including “Service Electronic Braking System,” ABS warning light, and traction control warnings, accompanied by constant audible alerts. As a result, multiple braking safety systems are disabled, including anti-lock braking, stability control, traction control, and cruise control. For several years I contacted Ram dealerships and the manufacturer regarding this issue and was repeatedly told that repair parts were unavailable. During this time, widespread reports of identical failures were being discussed on owner forums and among dealerships. A federal safety recall was eventually issued for the ABS control module, and I received my official recall notification letter approximately one year ago. Despite the recall being active, the manufacturer and local dealerships continue to state that no replacement parts are available and that there is no estimated timeline for when a remedy will be provided. As of today, my vehicle remains unrepaired and continues to operate with disabled braking safety systems and constant warning alarms. This is a heavy-duty truck that is regularly operated in Iowa, where inclement weather conditions including snow, ice, and heavy rain are common. I am concerned about the safety risk posed by operating a vehicle with compromised braking and stability systems a

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
