The abs control module has gone bad. When you take it to the dealership ship to get fixed they can-??t order the replacement parts. The abs system is very important in heavy truck like these when it comes to drive on wet roads.The manufacturer should become responsible for making sure it get fixed and their is parts available to do so.

Antilock brake system control module failed causing loss of ABS.

- Norman, OK, USA

Getting the same check engine warnings that many others are getting. Class action law suit going on in California.Ram says not covered by warranty

- Milford, NH, USA

ABS hydraulic control unit: Warning light and audible "ding" on the dashboard notes there is an issue with the ABS system. After taking this truck to several RAM service centers, the service tech says that it is part of a recall and that parts are not available. I cannot find any such recall, only a class action lawsuit. I haven't noticed a lack of breaking capabilities although I also have not engaged the breaks to the maximum which is where the ABS system would normally engage. Warnings are now constant while the truck is running.

ABS/Electronic brake indicator light on continuous, no Dodge repair facility cannot seem to fix issue. This should be a recall item.

- New Bern, NC, USA

Hydraulic cont module/ abs module is constantly going in and out causing the abs/traction control to be disabled and non functional cruise control. Highly unsafe when towing heavy like I do most of the time.

- Cambridge City, IN, USA

Intermittent ABS/cruise control failures and warnings. Disables trailer brakes while towing. Truck has 28k miles, has been repaired once already. Dealer says no recalls, and out of warranty. Subject of class action lawsuit?

Intermittent ABS Light on slippery roads. C0020-01 Code found by dealership. Warranty does not cover failure.

- Sacramento, CA, USA

Vehicle keeps getting ABS control valve general power fault. Code scanned is C002001. Indications in vehicle are 1. Cruise control suddenly disengages if in use. 2. Instrument warnings of "ABS Control Failure" and "Electronic Braking System Failure" continue flashing for 10 seconds or sometimes constantly. Keeps happening to me on long trips away from home. Never locally. Gives the driver no idea if system is safe to drive or not. RAM forums on line are full of these complaints. I believe a recall is in order.

- Lexington Park , MD, USA

My ABS/TRACTION CONTROL Electrical warning is coming on and shuts my cruise off. When driving at highway speeds and towing, this has caused me to swerve some and come close to be rear ended. I had the system replaced at 48000 miles for the problem and it is doing it again at 103000 miles. I can tap on the electrical motor on the system and get another week of use without warnings

1. My truck is randomly throwing a C0020-01 code. 2. When the code is active the traction control and cruise control are disabled abruptly causing a safety concern. 3.

Fist happened on or around May 1st, 2024. Warning message on the heads up displays "C0020-01 Active, ABS PUMP MOTOR CONTROL-GENERAL ELECTRICAL FAILURE".

The ABS Light is on and my ABS braking system on my 2018 RAM 2500 doesn't work. I drive on icy roads for at least 6 months out of the year. I need to have the ABS working on my vehicle so I can stop on icy or wet roads and not cause an accident. I scanned the code C0020-01(ABS Pump Motor Control - General Electrical Failure) using my Innova 6100P scan tool. The problem first occurred on [XXX]. RAM wants over $1,000 to replace the defective component. Dishman Dodge/Ram in Spokane, WA has confirmed this problem with their scan tool. My 2018 RAM 2500 is available for inspection upon request.

- Metaline, WA, USA

2018 Ram 2500 diesel truck, ABS braking system was intermittent and now has stopped working all together affecting the cruise control and the ability to stop without locking up the brakes all together. This has started a couple of years ago and the dealer said everyone is having the problem and parts are hard to get.

ABS Service light flashes on after rainy days and or going over a bumpy road.

- Elmira , CA, USA

The service electronic brake system light flashes intermittently, along with the traction control light and ABS light. Seems to occur when for no reason.

- Sperry, OK, USA

ABS and Traction control light indicators on dash appeared intermittently. After diagnosing from the dealership, it is advised to changed the Antilock Brake System module. However, the dealership advised there is a block and that they must first change the Hydraulic control unit, although they say it is perfectly fine. While we have not had an accident (luckily) it appears there is an ongoing investigation and multiple lawsuits against Dodge/RAM/Chrysler for this systemic problem of faulty ABS on 2017-2018 Ram 2500/3500. My 2018 RAM 2500 only has 36,000 miles. This failure is premature and potentially very dangerous. The dealer could not advise whether my truck was safe to drive or not even if the indicator lights were off or on. I have not yet had the HCU replacement completed, however will have it completed next week. I am submitting this incident report as a pro-active report as this is a serious safety issue and one that is systemic across too many 2017-2018 Ram 2500. The manufacture is not allowing replacement of the ABS Module until the HCU is repaired which is an additional (Double) cost to the consumer.

While driving while it was raining earlier this year, the abs/ anti lock braking system service initiated on the dashboard. It now acitivates intermittenly. During my investigation into the issue I've found that this is a persistent problem with the Ram 2500 /2018 year model and newer and that there is a class action lawsuit that has been filed. I used a OBD11 reader and it threw a code ( C0020-01 )

ABS lights flashing

- Oklahoma City, OK, USA

The ABS light and traction control light comes on and off over and over again. When it is on, its seems to not work as well on slick surfaces. I have seen that there are numerous complaints of the same thing on these trucks. I have been told it is not under warranty by a dealer. Only 21,000 miles. I purchased the truck in 2019. I put a code reader on the truck and it came up with C0020-01. 1. ABS Pump Motor Control 2. Recirculation pump- General Electrical Failure. The truck is avalible for inspection.
