2018 Ram 2500 brakes complaints
Page 33 of 79: complaints 941 to 970 of 2,349, newest first, as owners wrote them.
Antilock braking system lights started coming on intermittently about 2 months ago. It would occur then stop for a few trips. It has progressed to a constant alert with a notice to have the ABS system serviced. The vehicle has less than 50,000 miles on it and is not used daily. It has been in the shop for over a week and they have not returned my calls as to the diagnosis. I have read that there have been alot of issues with this.
[XXX]. Location : somewhere in rural Pennsylvania. Incident ahead of me in heavy traffic. Applied brakes, more forcefully than usual. Immediately warning lights and audible alarm appeared on dash. “Service ABS system” . Was located in very rural area , no safe place to exit highway. At next exit , pulled off , brakes appeared to be functioning as normal. But dash warning lights proclaimed no ABS system and no traction control. Also lost function of cruise control and trailer brake control.. cautiously proceeded to destination. Relative had code reader - revealed code C0020-01 ABS Pump Motor Control. Investigation on internet revealed this is a very common problem among Ram 2500 trucks. Very expensive and not covered under warranty. I believe the federal safety agency has received numerous reports from other Ram owners as to this problem. This situation is very unsafe with the loss of these very important safety features. Ram has refused to address this issue. I’m reporting this today in hopes that this agency dedicated to Safety will address this in a very timely manner.

Yes, I am on my second ABS brake module at 102,000 miles. The first one happened around 70,000 miles.
Issue with the Hydraulic Control Unit. It requires replacing.
ABS light and traction control light comes on – says service electrical break system and antilock brake system
Service ABS light on dash comes in every few seconds while driving. When this happens cruise control shuts off and ABS system does not work. The issue started happening with about 45,000 miles on the truck.
Hi, The ABS System shows Service Antilock Brake System at the display, It comes and go so I assume that it is an intermittent issue, it does stays for hours or days and go on ad off during the whole drive, definitely is an issue. It allow the brakes to preventing locket when brake on certain circumstances. Had an issue on a wet pavement and have to handle to avoid crash with other vehicle cause the tires got locket and the truck slipped on the pavement for a considerable amount of feet's. Dealer inspected and replaced the module under warranty when I bought the truck and told me that it has to be replaced again.
Traction control, electronic braking system and ABS warning lights flash and ding repeatedly with a warning message to service ABS system and Electronic braking system. Dealer and local shop cannot obtain parts. I need a safe truck for work.
My ABS light keeps coming on and off intermittently causing my cruise control to be interrupted and causing vehicle to slow down unintended in traffic. doesn't stay on and only comes on and off when it feels like it. This is dangerous and could cause my brakes to not work properly or have someone hit me from behind when cruise control kicks off at high speeds on the highway. This should be recalled.
HCU and ABS module brake failure causing the ABS and traction control warning lights and audible tone to intermittently go off. This also results in the cruise control failing to work. This is the second time of such occurrence. First at 3 years old and 30k miles and second at 6 years old and 50.5k miles.
The anti-locking braking and traction control warning lights flicker along with a beeping. This causes the cruise control to also disengage. This first occurred when the 2018 truck was slightly over 3 years old and with 30,000 miles. I had both the HCU and ABS module replaced and it stopped the issue for a few years and 20,000 miles longer. At 50,500 miles, it has again become an issue.
ABS Hydraulic Control Unit intermittently malfunctioning while driving causing service ABS system warning to display and render ABS system along with Traction Control System and Stability Control inoperable. HCU electronic motor removed and internal inspection of brushes and motor components conducted. Inspection identified brushes sticking in guides causing intermittent contact with center shaft of motor. New HCU ordered 28 June 24.
Service ABS braking system keeps appearing intermittently along with traction control and ABS lights illuminating on instrument panel. NO RECALL for this problem has been issued and parts are expensive to replace. Please direct manufacturer to fix issue immediately. Thank you for your mission to ensure the safety of others!!
The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, there was an audible alarm activated and the messages "Service ABS" and "Traction Control" were displayed. The contact stated that while driving on wet pavement, the vehicle was difficult to stop while depressing the brake pedal due to the failure. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet notified of the failure. The failure mileage was 60,000.
Second time my truck has thrown a code for the HCU being defective.
Have 47000 miles on truck and abs light kicks on and off. When it was checked code was abs general electrical failure.
Abs and service electronic braking system warning lights continuously go on and off while driving truck
The Hydraulic Control Unit begins to malfunction presenting on the ECU as C0020-01 ABS Pump Motor Control-General Electrical Failure. This is fairly common in 4th generation 2500-3500 RAM trucks. The malfunction affects the ABS system, Traction Control system, and Adaptive Cruse Control system by deactivating them when the malfunction presents. This could cause the braking system and other systems to not perform in hard breaking/ emergency braking situations causing the operator to loose control of the vehicle. The Traction Control system and ABS system warning lights illuminate on the dash and the message of "service electronic braking system" is displayed on the HUD.
HCU for ABS has failed - Intermittently fails when in operation. Basically hit a bump in the road and it fails. Hit another bump and it "fixes itself". Then hit another bump and it fails. Lights up the ABS light, ESC light, brake light, esc. After some research, this seems to be a common issue on the 2018 Ram 2500's.
I have had the ABS system failure happen for the third time. the first was around 24000 miles about May of 2020, repaired at a Ram dealer in New Mexico, I believe they only replaced the ABS ECU. The second time was 43,298 miles [XXX] 2022, they replaced the HCU AT Walker Ram in Alexandria Louisiana. It has now failed again with 65,723 miles on [XXX]. Every time it has cause the truck to lose the Anti-lock braking ability, traction control, cruse control & ETC. I feel that Ram should do a recall and fix the issue with a upgraded parts that doesn't fail every 20k so miles and cause a safety risk.

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.
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
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.
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.
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.
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.
