My 2018 Ram 2500 has Service Electronic Breaking System and Service Antilock break System, along with the traction control light coming on and off intermittently and will stay on for days the cut off and back on and off. I had a close call when a vehicle slammed on breaks in front of me (who knows why, it could have been a small child in the road) as I pressed the break pedal my breaks locked up and almost slid into the opposite lane. Thankfully the condition where dry and I had just put new tires on the truck. I took the truck to the Ram dealership in Jacksonville NC, and was told the ABS/HCU PUMP HAS INTERNAL FAULT AND PUMP MOTOR FAILURE. The part was on national backorder with no ETA and have been asking for updates for what seems like over a year and the same answer; under investigation and still on back order.... my family and I are on a nerve racking (due to dinging and flashing lights on the dash) road trip from GA to NE. I almost forgot to mention we are unable to use the cruise control functions due to the ABS/HCU/Traction control issues.. I understand there may be a class action lawsuit for this year make and model... What will it take to get an actual recall on these issues" Serious injuries, death" This should fall under the Lemon Law Act.

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.

ABS Pump failure: First occurrence July 18 2022. Mileage 24268 ABS pump replace under warranty by dealership. Second occurrence: July 23 2024 Mileage 45907 ABS pump not replaced as of yet, parts out of warranty by one week. OEM warranty out by 25 months. I am the original owner and this vehicle has been gently used and not abused. The ABS pump failure, two occasions, of a part which should be have a life expectance of 100,000 miles, minimum.. Two failures at less than 50K miles in my mind is not acceptable, especially with a safety related part. From the research I have done, additionally talking with other owners and dealership technicians, this is a common problem especially with the 2017 - 2018 year model vehicles. Something should be done to rectify this issue.

The hydraulic control unit (HCU) and the anti-lock braking system (ABS) module, not sure which one. They will only work intermittently or not at all; this causes the warning lights/chime to come on/off or just stay on. During this action the vehicle has no ABS or traction control, this is the Third time my vehicle has needing this part serviced with out-of-pocket cost as well as wait times for the part to actually arrive at the dealership.

Twice while going up a hill in the rain I was changing lanes and the cruise cut out causing the vehicle to slow down rapidly and kick out in the back. The cruise abruptly stops when the -??service electronic braking system-?? and -??service abs-?? lights and dinging come on. Apparently this also stops the traction control from working. Looking on the internet and forums, this is a very common issue. In fact, there is safety recalls on later model Rams with the same issue on the same parts. Why not the models that this started with?

[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 NHTSA 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.

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.
