The worst model year for it is 2018.
Recall C4B The Antilock Braking System in a constant On-Off state of failure. I've been told by multiple dealers and Ram Customer Service folks that there are no parts available. I have also been told that they will be available next quarters and that was multiple quarters ago. This has been going on since December 2024. I'm not sure if the braking system will function as designed if put in an emergency situation at this point. I also am unable to use my cruise control, because every time it goes into a failure mode, it kicks off the cruise control. I'm not talking about alarming once in a while, it's constantly every few seconds sometimes. I just want my truck fixed, this is ridiculous.

The abs and traction control intermittently is unavailable making my cruise control unavailable...this is all due to a recall that the dealerships keep telling me they cant get the part to fix and hasnt been fixed...pay 57,000 dollars for a truck back in 2019 and cant hardly drive it cause its unsafe and gives me anxiety everytime it goes off
NHTSA complaint #11764057 — an unverified report by a vehicle owner.
This problem was finally acknowledged by Chrysler in November 2024 but so far there is no repair offered by Ram. That, to me, is an unacceptable situation. The defect was generally know on my 2019 Ram 2500 several years before finally be acknowledged by them. And now after finally acknowledging the obvious they are still not offering a fix. As a practical matter, the actual defect is in the brush holders used in the small DC powered motor attached to the anti-lock control module. Replacement of the motor takes less than an hour but Chrysler is not even offering a suitable redesigned motor. I am not sure which is worse: Ram's refusal to offer a simple motor replacement or the lack of enforcement of a simple fix by NHTSA. I wore out a set of rear tires in under 3000 miles of use because of this problem.
NHTSA complaint #11763936 — an unverified report by a vehicle owner.
My 2018 Ram 2500 has a continuous ABS/ESC/Traction Control failure related to recall C4B (NHTSA 24V‑896). The hydraulic control unit (HCU) is failing exactly as described in the recall. The ABS light, traction control light, and stability control warnings come on constantly, and the cruise control shuts off while driving. This is a safety‑critical defect that increases the risk of a crash, as NHTSA states in campaign 24V‑896. My dealer confirmed the recall but says the remedy parts are unavailable and may take months. I am driving a vehicle with disabled ABS and stability control because Stellantis cannot supply the required HCU replacement. I am requesting NHTSA assistance because the manufacturer cannot provide a timely safety repair. I also have a bad knee and can NOT drive without cruise control.

NHTSA complaint #11763589 — an unverified report by a vehicle owner.
While driving, the vehicle suffered a sudden, complete, and catastrophic loss of braking power due to a total failure of the brake fluid line. The vehicle had to be immediately pulled off the road to avoid a serious collision.The vehicle was transported to a certified Ram dealership service center (Southern Motors CDJR in Savannah, GA). Upon inspection, the certified factory technician discovered and documented a severe manufacturing assembly defect: the primary brake fluid line was routed incorrectly at the factory. Due to this improper routing, the line was resting in direct, constant physical contact with the hot exhaust pipe. Over time, the extreme heat from the exhaust melted completely through the brake line and the protective heat sleeve, causing an immediate drop in hydraulic pressure and total brake system failure.This is a critical manufacturing assembly error that poses an imminent life-safety risk and fire hazard to myself and other drivers of this model year. If this incorrect routing is widespread on the assembly line, it will lead to sudden brake failures at highway speeds. I am requesting a formal safety investigation into the factory routing of the brake lines relative to the exhaust system on the 2024 Ram 2500.

My 2018 Ram 2500 has a safety recall (C4B/NHTSA 24V - 896) for BRAKES AND TRACTION CONTROL and the remedy for this condition is "NOT CURRENTLY AVAILABLE" ??? I have contacted FCA recall assistance center and 2 different dealers and they all are "SORRY" but say there is nothing they can or will do. One dealer offered to replace the defective part with another defective part if I was willing to pay for it and said that it would probably fail again. How can the US Dept. of Transportation allow a "US auto manufacturer" to sell a defective heavy duty vehicle used to transport loved ones and haul heavy loads with DEFECTIVE BRAKES? To add insult to injury Rams new promotional add states "Nothing Stops Ram" (True statement - Not even the BRAKES)... I'm happy to report there has not been a serious accident to date but the driver and passengers do not feel safe when the bells go off and warning messages appear on the dashboard... Thanks.
NHTSA complaint #11763029 — an unverified report by a vehicle owner.
While traveling approximately 65 mph on a two-lane highway, I crested a hill and encountered a vehicle stopped in the roadway waiting to make a left turn. When I applied the brakes to avoid a collision, the vehicle's Anti-Lock Braking System failed to function properly, causing the wheels to lock and the truck to skid uncontrollably. To avoid striking the stopped vehicle, I was forced to take evasive action and steer into the ditch. Fortunately, I was able to avoid a collision, but the incident demonstrates a serious safety hazard associated with this recall condition. The vehicle is currently subject to an open recall related to the ABS system; however, the local dealership has informed me that the necessary replacement parts are unavailable and cannot provide a timeframe for the repair. As a result, I am left with a vehicle that is unsafe to operate and poses an ongoing risk to myself and other motorists. Additionally, the unresolved recall has significantly diminished the vehicle's value. With multiple warning lights illuminated on the dashboard and a known safety defect that cannot be repaired due to the lack of available parts, I am unable to sell or trade the vehicle at its fair market value. I am requesting immediate action to address this safety issue and provide a remedy for owners who are unable to have their recalled vehicles repaired in a timely manner.
NHTSA complaint #11762687 — an unverified report by a vehicle owner.
The recall for the HCU is not being taken seriously. My "service ABS" alert is constantly on, as well as my service 4 wheel drive (which is part of the HCU). My brake pedal will randomly shake when applying. I am worried that this will cause an incident and don't understand why we can't get this fixed under the warranty. It has been 2 years and nothing has been done.

I have the active recall associated with the vehicle listed. It’s been nearly 2 years with the active abs service light, traction control light, and inoperative cruise control due to those lights. Stelantis is not very helpful. Will not fixit yet. But says I can pay myself and some or all may be reimbursed. There is no reason it should take this long. Endangering lives potentially. I sent truck pulling all the time. And you buy these things with these safety options that should work. To be taking this long to remedy this. Is unacceptable

NHTSA complaint #11761017 — an unverified report by a vehicle owner.
I am filing a formal complaint regarding m y 2018 Ram 2500 which is subject to safety recall 24V-896 for a defective anti-lock brake system module and hydraulic control unit. This critical safety recall was issued in November 2024 and as of today 8/29/2026 it has been nearly two years, and the manufacturer (Stellantis/FCA) has failed to provide a remedy. My vehicle currently displays warning lights for the ABS, Electronic Stability Control and Traction Control Systems indicating that these vital safety features are entirely disabled. Driving a heavy-duty truck without functioning ABS or stability control poses an immediate safety hazard to myself, my passengers, and others on the road, especially when towing or diving in inclement weather. Because the manufacturer has failed to provide a remedy within a reasonable timeframe, I am requesting that the NHTSA intervene to compel Stellantis to expedite parts distribution or provide immediate alternative transportation (loner/rental vehicle) at their expense until my vehicle is repaired.
NHTSA complaint #11760638 — an unverified report by a vehicle owner.
I bought my 2026 RAM in Sept 2025. RAM knew about the recall but didn’t announce it until Feb 26. I found that out after I purchased it. The trailer brake module is faulty as you know. I bought it to replace my 2017 RAM that also had an unrepaired recall. I have a camper I would like to use but I am afraid to pull it. I call every week to check availability of parts. So far nothing. The vehicle also had a radio/entertains screen issue, which was fixed, but is having issues again as it doesn’t turn of when exiting the vehicle after shutting the truck off. Now I see it has another recall. I found this totally unacceptable. I would trade it or sell but cannot due to being so far upside down. I also had to sell my cows due to being unable to haul a hay trailer. All I want is this truck gone so I can get one I can actually use. Now I see on your site where it has another recall. What are my options?
