This is the second time the antilock brake control module has failed and this truck has less than 75k miles on it. The warning lights constantly come on and off and if I needed to brake I am not sure that my antilock brake system would work.
ABS lights flashing on dash, intermittent at times, sometimes all the time. Deactivates cruise and traction control. Dangerous when hauling loads. Sudden loss of cruise almost caused an accident.
ABS and traction control failed causing me to lose control on an icy road. I was able to regain control without hitting anything or having an accident but now I get an intermittent ABS control module service warning. When this appears the antilock brakes, the cruise control and traction control do not work. Once the light goes off all systems return to normal operation. It is intermittent and unpredictable. Parts are on National back order, I do not think replacing all of these parts is the issue. As dealers like to do… they just replace the whole system without identifying what the issue is. I do not think I should have to pay for replacing parts that are working properly. FCA needs to recall all of these systems and replace them at their expense!
The ABS module has to be replaced!
2018 Ram 2500 6.7L Cummins. While driving, at any speed, “Service ABS” and/or “Service Electronic Braking System” flashes rapidly and intermittently on gauge cluster display. During this, the “Traction Control Fail” icon displays. Additionally, the cruise control will automatically disengage (creating a safety issue through increased risk of being rear ended while at highway speeds) and the warning chime activates constantly leading to distraction while driving. The truck is essentially undriveable. It is incumbent on the manufacturer to remedy this problem. It’s a shame I cannot use this truck more than a few miles at a time. How am I to stop with my family of 6 inside the truck, towing a 10,000 lbs trailer on a rainy day at interstate speeds without functioning ABS? This is a serious design flaw and I encourage NHTSA to continue their investigation into Ram’s process for remedy as soon as practical. Strongly recommend mandatory recall.
ABS traction control warning comes on intermittently. This causes cruse control to disengage intermittently, and causes braking and traction to be compromised at times
My vehicle has 45347 miles. It started throwing "Service Electronic Braking system " and "Service Antilock Brake system" messages intermittently. While driving on highway, truck would abruptly throw these messages and turn off ABS, EBS and also cruise control. It appears to be a very common safety issue with 2018 RAM 2500. I took my vehicle to the dealer but he couldn't read the codes because they were off and didn't come on. This is a safety issue for driving a one ton pickup truck and especially if driven in wet conditions.
The service brake system and service antilock brake system light came on. This light comes on quite often and shuts off intermittently. The pick-up no-longer has anti-lock brakes, traction control, or stability control. When light is on cruise will not work which if it set and light comes on it will shut-off and cause vehicle to drop speed which could cause an accident. Last time I drove it it felt like the brakes were spongy or not really engaging, which almost cause me to go through stop sign on to a highway. I have not had a chance to take it in to get checked yet, and the parts to repair I believe are back ordered.
Brake ABS and traction control system is malfunctioning due to failed ABS Hydraulic Control Unit as diagnosed by Ram dealership. Malfunctioning includes illuminated warning lights for ABS and electronic braking system. Malfunction also effects use of cruise control system. Vehicle is available for inspection upon request. Safety is at risk due to unknown effects on use of ABS system. Problem has been diagnosed and confirmed by dealer. Warning lamps have been intermittently illuminated for several weeks.
ABS failed, cruise control and traction control are inop as a result. The risk is loss of ABS when traveling, especially on wet or snow and ice covered roads. It has not been inspected by a mechanic. The failure light is on in the dash cluster and I have clearly lost traction control and cruise control. This began on July 31, 2023.
ABS module and traction control starting going off while driving. I took the car to the dealer but refused to fix it despite being under warranty at the time. The ABS and traction control lights go on/off suddenly and my cruise control shuts down and I loose ABS braking which is CRITICAL. this can cause an accident and I am not the only one with this issue. 2019+ Rams have already been recalled for the same issue. I need to get fixed ASAP, I HAVE CHILDREN IN THE CAR WITH ME! Issue keeps getting worse and lights come on more and more frequent, so most of my driving is without proper brakes.
Dec 1, 2022, Service dept. at Local RAM dealer in Binghamton, NY, diagnosed and concluded that the vehicle requires a new abs hydraulic control unit. PN: 68143491AB was ordered (Order # 1201BP) At that time, Parts were listed as being on Backorder and unavailable until mid January, 2023. ?? Mid January 2023, Part still unavailable, New estimate of part availability was mid March 2023. ??? Mid March 2023, I'm now being told parts will not be available until mid August 2023 ??? At this point, it will be over 9 months to correct this issue.
A warning light comes on that there is a failure with the anti lock brakes and electronic braking system. The cruise control will also fail to work. When the roads where wet the other day, i was sliding to avoid hitting deer that began crossing the road. It took longer to stop than it should have. I'm concerned that living in Michigan with the inclement weather, it may cause a accident that could have been avoided. The vehicle was checked by a mechanic who said the control was going out. The incident started some last summer (I only have 22,000 miles on my truck) but it is intermittent.
Beginning at almost exactly 28000 miles, this truck intermittently shows a warning for a fault with the “electronic braking system” and the “antilock braking system” where there are multiple warning lights and tones, and the ABS, traction control and cruise control becomes inoperative. This has increased in frequency and occurs in any conditions at random intervals. Recently it has come on and off as many as 20 times in a 12 mile trip. I am aware of a current NHTSA investigation into these vehicles as well as a class action lawsuit against Stellantis. I have reported the condition to my dealer who advised it is not covered under warranty and no parts are available to repair it.
I have a 2018 Ram 2500 Diesel and throughout the past 24 months I have been receiving intermittent ABS and Traction Control lights while driving. Recently (3 days ago), the lights have come back, are staying on, and the screen displayed the words "Perform Service". I attached my diagnostic tool and the Code captured is: C0020 Status: MIL/Confirmed - ABS Pump Motor Control - General Electric Failure.
2018 Ram 2500 with 18,900 miles. While driving at various speeds, the ABS and traction control warning lights illuminated with an audible chime. The brakes would slip upon depression of the brake pedal while the warning lights are illuminated. ABS control module/traction control is intermittently failing. There is no antilock braking or traction control on wet/icy conditions.
Abs, stability control and cruise control are not working as they should. Dash is constantly displaying a warning error about the brakes and stability control.
During the month of July 2021 I would get a message to service the antilock brakes. At 16400 miles I took the truck to the dealer any they replaced the Control Anti-lock brake system and Module. Part numbers 68143491AA & 68347098AB. As of this week with 24400 miles on the truck I am getting the same intermittent message. The the message comes up with shuts down cruise control, makes a chime noise and turns on dash lights. The message will come up stopped to moving at any speed.
Intermittent failure of the electronic braking system. Audible Warning tone and indication "Service Electronic Braking System" followed by "Service antilock braking system" experienced intermittently. The multiple warnings automatically disabled the antilock brakes, stability control, and cruise control as well as producing annoying audible tone. This failure originally began occurring in August 2020 and was taken to the local Ram dealer in September 2020 when it was diagnosed as a defective 68143491aa hydraulic control unit module. After a three week lead time, the module was replaced under warranty with 12116 miles on the vehicle and the problem disappeared. Two years later in July 2022, the same warnings began intermittently with the same disabling safety issues at 24000 miles. On 10/19/2022, the Ram dealer diagnosed the problem as "Abs Control Module 68143491aa Has Internal Short. Part Is On Backorder With No Eta". I have repeatedly checked on the status of the part with the Ram dealer resulting in the same "Backorder with No ETA" response. In November 2022, I filed a formal complaint with Ram Cares. They have provided the same response "Unplanned resource requirement resulting in supply disruption. No firm ETA to provide at this time. Working to improve". This failure is a safety issue, not just an inconvenience and annoyance. My Ram 2500 is periodically used to haul a 10000lb trailer. The sudden loss of cruise control, stability control , and antilock brakes could cause and accident resulting in property damage and injury or death.
Service Electronic Braking system and Service ABS braking system messages with accompanying chimes occur every 2-3 seconds while driving. This turns off the traction control and abs as well as the speed control. Diagnosis reveals abs control module and hydraulic brake control unit needs to be replaced. Vehicle only has 60,000 miles. Parts are discontinued according to dealer site.
ABS Hydraulic Control Unit and Electronic Control Unit Failure. ABS MIL and Traction MIL began turning ON and OFF intermittently during daily driving, sometimes turning ON and OFF over 50 times during a 20-mile drive. Lights up the dash and sounds a beep to inform the driver, while displaying a message on the dashboard screen. Again, this occurs every time the alarm activates. No dealership was able to get me in for an appointment when the issue first began. Took into the dealership today for diagnosis. The technician immediately knew the problem when I said the ABS light was blinking randomly and noted that he has seen this with all 2018 RAM 2500s. The first safety issue is regarding the loss of situational awareness while driving caused by distracting alarm systems. The second safety issue is that ABS WILL NOT work if the alarm is active, effectively setting up the driver to be placed into a dangerous situation during inclement weather conditions where ABS might mean life or death during a hard braking situation. The ABS system is only covered under a basic warranty with Dodge (3yr or 36K). The ABS system failed around 36K, but due to dealership waitlists, I was not able to be seen until 41K. The cost for total ABS HCU and control unit replacement is around $1500.
39,125 miles - 2018 RAM 2500 6.4L (purchased new in 2019), intermittent ABS / traction control light and alarm dinging! Dealership diagnosed it as the ABS / hydraulic control unit with code C0020-07. Many reports of this same issue can be found online from RAM owners having this exact issue, most are just out of the warranty. Low or backorder status of the replacement parts also suggests an issue. ABS function and cruise control are disabled when the error occurs and no way to know when or how long the issue and alarm dinging will last. This is a major safety problem that should be a recall.
Service Electronic Braking System and Service ABS system lights are flashing intermittently and the ABS and traction control lights are on. Dealer has indicated the hydraulic control unit is bad and needs replaced but they no longer manufacture that part and there are no aftermarket offerings so vehicle cannot be repaired until parts are located. In the meantime these vehicles affected have no anti-lock brakes and the cruise control randomly shuts off if the ABS light flashes while cruise is enabled.
ABS Electronic Brake System warning. "Service Antilock Brake System" warning as well as "Service ABS System" warning. Warnings are intermittent. It is available for inspection. Traction control light is on and braking seems difficult. I have not taken to a dealer because of prohibitive costs. This vehicle has not been inspected as it is a very common problem for this model truck. The problem has been intermittent for the past year or approximately 5000 miles driven (with only a total of 48,000 miles on the vehicle.
Driving the ABS and Traction Control light comes on randomly, when on neither the ABS or Traction Control work when light is on. Cruise control is also not working when light comes on. Took Ram to dealer, they tested and stated a failure of ABS Module, took over a month to get in as they are in demand. Dealer stated this is a common issue and parts are backordered. ABS Module was replaced and system is still not working. This is a safety concern as no ABS and Traction control make the vehicle unsafe to operate. I do have the old ABS module on hand after dealer replaced old one. Dealer is trying their best, but always have one or two on lot with issue. Stopping and handling are hazardous when system goes out.
