Service ABS and traction control warning keeps going off. Cruise control kicking off.

- Lone Grove , OK, USA

I have replaced the HPU 2x's and currently the ABS warning light comes on. I have a RAM case #86697757. This is going on for a year and the dealer says parts are unavailable for repair. The truck has 24,000 miles on it.

My 2018 Ram 2500 has 85,000 miles currently. At about 80,000 miles I got the ABS and Traction control warning lights along with dash messages to check the ABS amd electronic braking systems. I am a heavy equipment mechanic and thus checked the systems myself with a scan tool and other test equipment. I found that the ABS module has an internal electrical failure resulting in power not being supplied to the ABS pump/electric motor. I have verified that the pump works and has about a 48ohm resistance. If supplied with 12v and ground to the motor it will come on. Circuit testing from the electrical plug to the contacts for the motor one pin has contact and the other is an open circuit. I also have one seized plunger in the hydraulic control unit that is actuator by the motors eccentric lobe on the output shaft. After doing some research online I've found this is a very common issue on the 2017 and 2018 Ram heavy duty trucks, the 2500 and 3500 model specifically. I also found that neither the hydraulic control unit nor the ABS module have been available for purchase for a long time. I myself have been trying to order one for about 6 months. No dealer in my area can even give me an estimate time of availability. So currently I and many other have to drive a vehicle with a failed ABS system. This poses a greater risk of collision and unsafe braking. It is also a requirement to be working to pass a vehicle inspection so selling the vehicle or depending on state lived in you may not even be able to drive the vehicle at all.

Several systems suddenly were disabled, ABS, Electronic Stability Control, Front & Rear Park sensors, Tire Monitor system as well as the cruise control that may not be considered safety. The truck only as 11K miles. I have not been able to reset the system and the noted systems are inactive. I will contact the dealership but am bracing for a less than supportive meeting. From what I've read this is a very common failure on this year and model truck

July 11, 2024 Message alert appeared indash with instructions to service ABS system. This vehicle experienced the exact same issue in April of 2022 and was taken to the dealer(Patterson Dodge-Tyler, TX) for repair, where the ABS Module was replaced. The replacement was not covered by the warranty.

My ABS light sporadically comes on and off. Dealership says it is the HCU module. It was replaced under warranty in 2020 and now has failed again. Wanting to file report so it is noted to help with initiating a recall on this failing part. I have read that the ABS module has also had similars issues with no recall as of to date either.

ABS and ECS warning indicators are continually coming on and going off. I have read many complaints on Ram forums that are identical to mine.

The truck's warning lights indicate ABS module, HCU module, and cruise control failure. The trailer brake controller, ASB system, and cruise control does not function. The truck's warning lights and chime have been going on and off for over 2 years.

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

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.

Purchased vehicle new. ABS and TC lights presented on dash intermittent. Cruise control inoperative when lights on. Had issue under warranty and had components replaced to resolve issue and now happening again. Afraid to have family in vehicle with inoperative safety systems.

Abs module/hcu are intermittently shutting off and on. Brakes work, but you loose your abs. The problem has not been fixed. The abs module is on back order everywhere. It-??s a hard part to find new or used.

- Stockbridge , GA, USA

CONSTANT & iNTERMITTENT system notification (Dash lights and chime tones) of required ABS serving, Traction Control failure, and DISCONNECT of Speed Control system. The problem has been on going for past 15,000 miles. NOTE: Took vehicle to RAM Dealer in Kerrville Texas and they determined no problems despite dashboard messages and lights. Dealer states that they are NOT aware of ANY issues with ABS and Traction Control on any of the 2018 RAM 2500 vehicles.

ABS and traction control lights come on intermittently. Cruise control won-??t work when this happens. Problem seems to be a wiring issue and mainly happens during wet conditions and then stops after engine compartment warms up. I-??m guessing ABS brake-??s won-??t function when light is on.
