ABS/HCU modules have failed. A loss of ABS and braking power have been experienced. When towing, this creates a problem as it happens very suddenly and intermittently, placing myself and others at risk of loss of braking power. Warning lamps indicating ABS failure/electronic braking system service is needed come on only when braking, and is intermittent. There is no indication of a problem until brakes are applied.
2018 Ram 2500 brakes complaints
Page 54 of 79: complaints 1,571 to 1,600 of 2,349, newest first, as owners wrote them.
I have a 2018 Dodge Ram 2500 pickup truck and my ABS engine light came on back in February 2023 indicating that I have a problem with my braking and traction control system. It was because of the Hydraulic Control Module was bad. I Contacted a Factory Chrysler Parts supplier to obtain a new part to have it replaced but they were on backorder until June. In June I contacted them again and was told they were on back order until October 2023. I just contacted them again 9/27/23 and now I am being told the part is on back order until February 2024. This will be a full year causing me to drive without the ABS or Traction control not working, as well as not having cruise control. Doing a search on the internet there are a lot of others having the same issue which is bad enough but when you can't even get the replacement part for over a year on a piece of safety equipment for your vehicle . This is more then a safety issue.
While driving ABS and traction control lights came on and cruise control would no longer function. This has occurred 3 times and had to be repaired 3 times. 10/10/2019, 07/20/2021,and 08/19/2023. The parts replaced: 68347098-AB Module AN 08035030, 68143491-AA Control A 08035030, 68143491-AA Control Anti-LO 080, 68143491-AB Control Anti-LO 080. The parts are not available for inspection. Also, brake fluid 4318080-AD was replaced or added each time. These parts were replaced by authorized Dodge Ram dealers, one in Michigan and twice by a local Dodge Ram dealer in Florida. No warning of problem and vehicle still functioned except for cruise control. Problem first occurred at 3,305 miles, then at 17,161 miles, then at 25,203 miles
Recently the ABS Warning light and Service Electronic Braking System light have been coming on intermittently. When it happens an audible alarm goes off and several functions shut down, like the cruise control. The problem has no rhyme or reason and some days it happens for several hours and some days it never happens. I am concerned that the ABS is not working properly but also concerned that I might be using cruise control on the highway and it shuts down creating a hazard and possibly accident. I have not contacted the dealer but see that it is a common problem with my vehicle on online forums and that there are class action suits for the issue. This should be handled by the manufacturer with a recall before someone gets killed. Currently the dealers are making a fortune making repairs that often recur in a short period.
Keep getting “service anti-locking brake system” and “service electronic brake system” that intermittently turns off and on. 2018 Ram 2500 6.4L with 81,000 miles. Appears to be a common issue but no recall has been made.
The contact owns a 2018 Ram 2500. The contact stated while driving approximately 55 MPH, the ABS and stabili-trak warning lights illuminated. The contact stated that an audible beeping alarm was sounded. The contact stated that when the ABS warning light and other warning lights eliminated, with the Cruise Control activated, the cruise control would deactivate and needed to be reactivated by depressing the accelerator pedal. Additionally, the failure recurred while driving at various speeds. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle had not been diagnosed and had not been repaired. The contact had researched online and related the failure to the federal safety agency Action Number: PE22012 (Service Brakes, Hydraulic). The manufacturer had not been informed of the failure. The failure mileage was approximately 74,000.
The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated. The failure was intermittent, but it had since become a persistent failure. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 72,000.
I bought this truck new from the dealer. At 18,920 miles, the ABS service light came on and the dealer said the ABS module would need to be replaced. A new part was installed. At 49,715 miles the light came on again and the dealer says the module is defective and needs to be replaced again. This part is on back order for over 2 months telling me these items are in high demand. I don't believe that items like this should be defective and require replacement in this short interval.
Failure of the HCU (Hydraulic Control Unit) and ABS module. Caused loss of ABS system, Electronics Stability Control system, Electronic braking system, cruise control. Messages appeared on dash. All associated warning lights illuminated. Dealer stated this is a known problem and parts have been on backorder.
The "service electrical brake system" and "service abs system" lights / warnings have been intermittently going on and off. This also does not allow the cruise control to work. The alerts can range from once every couple of days to repeatedly going off non-stop during my drive. Issue started around Oct of 2022. Warnings will stop for several months then return.
My 2018 Ram 2500 has an intermittent ABS/ Service Electronic Braking System light. If I am using the cruise control when this light, comes on the cruise control turns off and the vehicle slows in front of moving traffic. I seem to also loose traction control which is dangerous when towing heavy loads.
ABS HCU/and pump failure. Truck dies. no Brakes
Antilock braking system and electronic brake system warning lights flash on and off frequently while driving.
ABS Pump Motor Control - General Electrical Failure, code C0020-01, needs to be replaced. A critical item. Part is not available. I live full time in my 5th Wheel 40’ RV. Part may be under some engineering review due to failures. I need new part asap. No dealer has them. Truck is grounded.
I am receiving an alert in my truck that states, "Service Antilock Brake System." The emergency warning sound and lights on the dash/display appear constantly. This also affects the "Speed Control" as it kicks off the cruise control when the emergency warning sound and lights come on the dash. I have taken the vehicle to a RAM Dealership who diagnosed the issue, but was advised that parts are on backorder, which is unacceptable as this can be a very dangerous and potentially costly situation. I believe that the federal safety agency should look into this and provide a recall on the vehicle and expedite the process to getting, not only my vehicle, but others around the country fixed in a timely manner.
The “Service Anti-Lock Braking System” warning turn on and off intermittently and the yellow “ABS” and “traction control off” icon turn on and off intermittently about every 4-5 seconds. In the morning after first start, the warning lights and message proceed after the first brake pedal application. I have 78,500 miles on the truck.
Service ABS system/ Electronic break system warning light came the dash control. When that happened in September of 2020 I lost traction control and cruise control on my truck. Since this accrued I’ve had several near misses of accidents do to lose of ABS system. I have not had it looked at by the dealership due to the fact that two family members have the same truck with the exact problems. They took their trucks into dealer. The 2021 was fixed under warranty and the 2017 truck was repaired out of pocket to dealership.
The ABS/Traction Control System (TCS) error flashes intermittently while driving the vehicle. This dash warning states the ABS and TCS systems are non-functional. The vehicle is available for inspection. Safety is adversely impacted by the braking system not performing its design function. Traction Control perturbations can also have adverse impacts to the drivers control of the vehicle. This vehicle has has yet to be inspected, but similar failures for this make/model indicate a faulty ABS module and/or sensor issue. Warning error messages are broadcast frequently via the instrument cluster display. Initial warnings @ 32k miles, fall of 2023.
My truck has 32000 miles on it. Its just out of warranty and the ABS Hydraulic Control Unit is out again. This will be the third HCU put into my truck. This is a known problem from Ram and it has never been addressed. the federal safety agency please have RAM make it right and fix the problem so costumers are not spending 1500.00 every 15,000 miles.
ABS, and traction control systems fail intermittently. Lights come on and flash and ABS and cruise control no longer work. Happens at various speeds and times. Sometimes can be addressed by pulling over turning off the vehicle and restarting. Dealer states that ABS module and pump need to be replaced but have no available parts. I was advised that the estimated cost is ~ $1800 and the problem may arise again. This is on a vehicle that has less than35k miles
ABS Module failure and Hydraulic Pump failure.
Service ABS and Traction control warning lights on. Computer says ABS circulation pump is bad. Part is unavailable. There should be a recall, this is a known and documented safety issue. Part is discontinued, how is it possible to disregard this issue? What are we supposed to do........drive a vehicle that wont stop as it should?
The ABS/Traction Control light continually goes on and off. I took the vehicle into Tate Dodge Ram Service center in Glen Burnie, MD the first week of January 2023. They diagnosed the problem as the ABS Control Module and Hydraulic Control Units as bad. I was told that it would take 2 weeks to get the parts. I checked back with them 2 weeks later and the ETA had changed to March 16, 2023. I left the vehicle with them and checked back after March 16th, the ETA had then been changed to August 15, 2023. I picked the vehicle up from the service department and check on it August 15th. They had received on of the part, but the other one was scheduled to be delivered Sept 15, 2023. I contacted them again on Sept 18th, when I was told that the part would not be delivered until February 15, 2024 (13+ months). The lights continue to go on and off with a bell each time the light comes on, which is very distracting. It is unsettling to drive, not knowing if my brakes will work in an emergency or if the traction control will work when we get slippery road this winter.
ABS goes on and off continuously. Warning messages and beeps constantly. Started October of 2022. Independent service center has been trying to get a replacement nodule from the manufacture for all most a year.
Service electronic brake system keeps coming up on the dash. When this happens you lose cruise control, ABS, and your abs and traction light come on. This goes on and off constantly and dings every time it happens. This is a huge problem that Chrysler is aware of but will not do anything about. I had mine replaced once and 23 months later I have the same 13000 dollar issue.
I have a 2018 Ram 2500 - 6.7 Cummins diesel, The service ABS system and service electronic brake system dash lights come on and go off constantly. Every time they come on there is an alarm that goes off, and it also kicks the cruise control out. This problem started had around 32,000 miles and has continued to now 71,000 miles. I have tried multiple times to have this, diagnosed with a system reader with no luck. Have had the system reset also with no luck. I’ve read on multiple Dodge/Ram forums that this is an ongoing problem with 2017-18 and up Rams that they refuse to address. Any information would greatly be appreciated to get these problems resolved as it appears there are multitudes of people having the same issue. Thank You Note: The mileage on the pictures below is not when the problem started, these were a picture of the lights that I could catch in between them coming on and going off so I could show the mechanic what was happening.
About a month ago the ABS and Traction Control warning dash lights started coming on intermittently with warning tone. They go on/off randomly or not at all some days. I had the codes pulled and there was only one, C0020-1 General ABS System Failure. This has not resulted in any dangerous vehicle incidents as of yet, but I must have my vehicle to tow/work and the expensive replacement parts are on indefinite back order. I understand this is a very common problem for 2017-2018 Ram HD trucks and Ram is doing very little to prioritize a solution.
The hydraulic control unit (HCU) of the anti-lock braking system (ABS) is defective (part number 68143491AA). Without warning the defective HCU will cause the ABS and or cruise control to shut off. If this happens during hard braking, on slippery terrain or in heavy traffic, it could cause an accident. The indications the system is having a problem are warning messages on the dash display, which is great, but the warnings goes on and off for no apparent reason (does not stay on). This can happen at any speed. I replaced my HCU with the same part number (68143491AA) approximately one year ago. This corrected the problem until a couple of weeks ago when the same indicators started again. After a lot of research (Google, Ram heavy duty and Power Wagon forums) I came across one post that discussed how a brush in the motor for the HCU can become stuck, failing to maintain electrical contact with the motor windings. With nothing to lose, I decided to pull the motor off my HCU and take it apart. Once apart, I did determine that one of the brushes was in fact stuck. I am not sure if the brush became stuck just because of dirt or if the metal body the brush slides in was crimped too tight (could be a combination of both). I was able to free up the brush and put the motor back together; the motor functioned properly when bench tested. Unfortunately, I have not been able to reinsert the motor back into the HCU body (plungers are in the way and need to be compressed). I do not know if this requires a special tool, and my research has not come up with anything. Ram has apparently corrected the problem with an updated part, part number 68143491AB. Unfortunately, I cannot find anyone that has this new part in stock. As this is a safety issue affecting a lot of Ram trucks (check the forums and you will find a lot of people discussing the issue, so this is probably way underreported to the federal safety agency), Ram should replace all 68143491AA with 68143491AB under a recall.
The ABS module is bad. Can not drive the vehicle for fear the brakes will fail, especially when pulling a trailer loaded with animals (farm). This is ridiculous, a $86K vehicle with less than 40K miles (we have not driven the truck in over a year) because of a faulty part that the company will not own up to. PLEASE have MOPAR/RAM/Chrylser own up to this faulty part and issue a recall ASAP. When the brakes lock up and someone dies, that will be a real issue. Sincere thanks,
I started getting a "service electronic braking system" message in the EVIC intermittently
