At around 74,000 miles in December of 2023, a warning to "Service Electronic Braking System" and "Service Antilock Brake System" started to show up on the screen of my 2018 Ram 2500 6.7. The truck was taken to a Ram dealership and the fix to the problem was determined to be replacement of the ABS module in addition to replacement of the HCU. Apparently, the ABS module is faulty and is causing the HCU to go bad so both need to be replaced. Replacing only the HCU will not fix the problem. The truck has not yet been repaired as a new ABS module is not available until June of 2024. When driving, the on screen errors come up frequently at all driving speeds and the error is present the majority of the time while driving.

The ABS module is defective on my truck which controls the antilock brakes, Anti slip function, and the cruise control. Dealer ship has diagnosed problem and ordered parts but the parts have been on back order for quite sometime with no ETA from RAM when parts will be available. My dealer ship says they currently are wating on 25 parts for different vehicles with same problem.

Got a code for service abs system, abs module pump bad. Ram cannot even get people in to fix the issue and they want like 2000 dollars out the door to fix this unsafe issue. I also have no cruise control now and no abs. This is an absolute shame that my truck only has 66k mostly highway miles and is now worthless because I cannot afford to fix it. Ram will not fix this issue under warranty. There is a current lawsuit under James Neu vs. Fiat Chrysler to get them to make this a warranty issue and fix it. Please please please release the recall so we can get our trucks fixed! Thousands of trucks are affected and at risk of accident. Thankyou please let me know if there is any hope in the future of this recall. I don-??t know if I should just wait it out or get rid of the truck [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

As with thousands of other owners with this model of truck my anti-lock control module is bad. The malfunction causes the anti-lock brakes service light as well as the traction control service light to be on. This malfunction renders both systems to be inoperable, thus causing a major safety concern.

ABS & traction control lights on along with messages reading "Service Antilock braking system and Service Electronic Braking System. 1st intermittently then very often. Code C0020-01 is stored in the system via OBDII scanner. It is available for inspection at any time. I can not tow anything that requires trailer brakes because I here, through many other online complaints that trailer braking will be inhibited. I have not yet taken it to the dealer yet because it is out of warranty and the part required to fix it properly won't be built/available until Feb 2024. I first saw warning lights/messages in July of this year 2023 with around 37,000 miles. See attached pics.

The ABS and Traction Control lights flash and ding on/off intermittently. Sometimes the lights on the dashboard come on as soon as I leave the driveway and sometimes it takes several miles. But once they flash on and ding on the dashboard, the lights flash on and off intermittently for seemingly no reason at all. I am not sure if this is due to an electrical issue, a hydraulic control unit issue, or something else, but something is not right, making the lights and dashboard flash/ding a lot.

Took my Vehicle to dealer for abs and traction light displayed on dash. Dealer states my truck needs a new HCU and control module. At 28,000 miles these same parts had to be replaced for same issue. The truck now has 63,000 miles. To top it off abs, cruise control and 4x4 does not work or quits working when this warning is displayed. It-??s absolutely ridiculous how many ram 2500-3500 owners are having this issue over and over. I would hope you all will step up and demand a recall be performed.

The truck intermittently shows an alarm for failure of the abs braking system. This suddenly shuts off the cruse control and disables the abs. The loss of cruse control caused the truck to suddenly drop in speed in a highway traffic situation, which nearly caused a car behind me to hit me. The loss of abs leaves the truck vulnerable to brake related accidents in slippery or wet weather. I contacted a dealer for the replacement parts and they told me they would not be available until a new generation of abs module and hydraulic control unit were available. I believe the NHTSA should demand a recall for this extensive and dangerous issue.

The radio screen has delaminating which causes random pushing of buttons on the display. This is a known issue with dodge radios and has been labeled as -??ghost screen-??. This is a major concern during the day as well at night while trying to drive. The distraction from the constant screen changing is a major concern. It is unavoidable to focus on the screen instead of the road while this is happening. Dodge knows of this problem and the repair cost is unaffordable. I feel for the safety of drivers and people on the road, this needs to be addressed. I have videos of this occurring but am not able to upload videos, only photos which do not show the event happening. I would like the chance to be contacted so I can share the video of this happening to express my concern, as well as the concern of many others. Thank you

My ABS module and HCU are acting up. Warning lights on dash keeping going on and off intermittently stating service Anti Lock Brake system and Service Electronic Braking System. Traction Control loss warning light accompanies these lights. I have had the module replaced twice already and still not working. Was told yesterday (Dec 07,2023) by warrant repair facility that there is a new upgraded part available and to file a complaint. These problems started in October of 2023.

ABS Module Failure. Truck is available for inspection upon request. The ABS Module Failure directly effects the safety of all occupants and other vehicles on the road if not able to stop as intended to. The problem is confirmed by a dealer. There were no warning lamps until the ABS Module failed and needs to be replaced. This is a standard issue that needs to be recalled.

Abs module is out again. Second time in just over a year since I replaced it last time. This is an ongoing issue and numerous people locally are complaining, so national has to be thousands. Ram is aware of the issue but not fixing.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the ABS and Traction Control warning lights illuminated on the instrument panel. The vehicle was taken to the dealer, who diagnosed a failure with the ACU, causing a general electrical failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 50,000.

ABS light and traction control warning on dash. Truck has been in shop previously for the same issue. This causes my truck to lose cruise control at highway speeds and to not have traction control capabilities when driving on wet roads. I will be taking the truck back in to the shop this week as this is occurring at all times and does not stop dinging.
