On 8/10/2024 at 3.10 PM while traveling 68 mph on an interstate, the vehicle started displaying Service Electronic Brake System and Antilock Brake Failure warnings. This also shut off the cruise control system, causing a sudden and unexpected loss of forward momentum. The warnings would reset and then come on randomly while travelling.
2018 Ram 2500 electrical complaints
Page 6 of 17: complaints 131 to 160 of 476, newest first, as owners wrote them.
Got an ABS fault for a corrupt hydraulic brake unit. So I replaced the unit at the cost of $200.. once replaced I still had an ABS light, traction control light, Brake light. Reading the codes it would tell me that both rear wheel speed sensors failed to compare. Ultimately I got a check engine light for wheel speed sensor 1 failure. So when I rest the code it clears the lights and I lose the speedometer for 25 plus miles. Also renders the 4x4 feature useless on the truck. I took it to the dealership on 8/8/2024 and they attempted to do an update to the ABS module. After the update I lost the speedometer again. I was told that the ABS module will need replaced at the cost of $600 plus labor and program time.
The electronic braking system/abs light/traction control light constantly comes on and off every few seconds when driving. Having intermittent loss of anti lock braking system is a hazard.
Driving in normal conditions .. even leaving my driveway ABS light comes on and traction control light comes on. and flashes randomly. Sometimes in doesn't come on for a bit but then will flicker on and off.
ABS braking Module and hydraulic control unit on this vehicle has been replaced under warrenty twice (in 2020 & 2022), vehicle now has 59K miles now and ABS has failed again, dash warnings are constant and cannot be turned off. Failed while driving from MO to FL last weekend
C0020-01-ABS pump motor control - general electrical failure
Abs light and traction control light continue to turn on and when they light up my cruise control stops working
ABS notification light and traction control light keep beeping.
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 federal safety agency 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 light and traction control light come on and off- sometimes stays on and sometimes fluctuates. Been a constant occurrence
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.
Anti lock brake module repetitively fails. First one replaced 7/2021 with 51,xxx miles. Second failed 7/2024 with 69,000 miles. Loses ABS system, cruise control, electronics affect electronic throttle and stabilitrack.
ABS and Traction control warnings intermittently go off and sometimes stay on for a while. This causes the truck to not have abs and traction control. Had a bucking issues sliding down a boat ramp yesterday. Truck is under 40,000 miles. This is a well known issue for years now.
Service ABS and traction control warning keeps going off. Cruise control kicking off.
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.
ABS lights flash on and off while driving constantly. Affects concentration and cruise control. Radio will randomly start pressing all over the screen changing settings and distracting the driver.
Abs system failed and had to brake hard causing the wheels to lock up and lose control of the truck ,lost speedometer, brake lights, 4x4,cc,trailer brakes
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 light and traction control light would come on intermittently while driving then stayed on causing cruise control to not work. been happening for over a year
ABS light and traction control light comes on – says service electrical break system and antilock brake system
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!!
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.
