The systems in question are the ABS and Traction Control Systems on my 2018 Ram 2500 6.7L 4x4 Heavy Duty. This vehicle has had issues from the beginning with these systems as the first repair took place at 10,640 miles at the dealership it was purchased from. This took care of the codes/lights for a short period and was covered under warranty but the same issue persisted not too long after mileage-wise. The next time this issue occurred was when the truck had 22,628 miles, the brake fluid was flushed in an attempt to correct the ABS light but was unsuccessful. The truck was then brought to another repair shop to correct the same issue again where the ABS Hydraulic Module, ABS Control Module, and the brake fluid were replaced at 23,702 miles at the sole cost of the owner. As of early July 2024, at 45,000 miles the lights have again started intermittently coming on stating there is an issue with both the ABS and Traction Control Systems and must be serviced. After reading through multiple forums and speaking to other owners, this seems to be a common occurrence and needs to be looked into by the NHTSA due to major safety concerns. Although there were no accidents or police reports in this case, this malfunction poses a major safety hazard for the driver, passengers, and others on the road if a recall is not issued. There should be no reason a $60,000+ heavy duty premium truck consistently has these issues with no accountability and/or repercussions held to the FCA group. My personal concern is for my family as this is our primary vehicle and living where we commonly have inclement weather, if the ABS and Traction Control Systems fail randomly during a storm, this has a high potential to cause major injury or death to both our family and other drivers on the road. Not to mention the potential cost of collision damage to the vehicle(s) and/or other person's property.

2018 ram 2500, abs and traction control light came on and front driverside brake locked up cause me to lose control of the truck. Almost hit 2 other vehicles. Now there's a loud grinding noise and seems to be not drivable. Vehicle was towed to my local dealer this morning 7-29-24 (kendall jeep ram chrysler). Was told by a service advisor that I could possibly be a faulty abs module but they do not have any available diesel technicians available to diagnose at the moment. Might be serval days or weeks before they can troubleshoot.

Abs control module & HCU module not working properly. Ram brand knows about these problematic modules on the 2014-2018 rams trucks. Now, I can-??t drive my truck since Ram fixes this issue.

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

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.
