Service electronic brake system and service antilock brake system comes on intermittently which disables traction, cruise and antilock brake control systems when it happens, very dangerous in slippery weather

- Burlington , NJ, USA

Lost braking power. Anti-Lock brakes quit working. Lost cruise control. Unable to use anti-lock brakes. Brakes locked when stopping. Flashing dash alarm saying service ABS/Electronic Braking System. All occurring without reason, just randomly. This puts my safety and the safety of others at risk as the brakes lock up when depressed at times as well as loss of braking power.

Brakes seem to be intermittent. Check Electric Brake warning comes on every time you start the truck and has shutdown the ABS and cruise control options. This is a very big problem if you research it on the internet on Ram and Mopar forums.

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 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 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.

The electronic brake light and ABS warning goes off intermittent and with hitting bumps. When this happens the cruise control shuts off. This leads me to believe that the antilock brakes and and will malfunction in a panic stop. This is a repeat issue, dealership has replaced the HCU and ABS modules twice within a three year window.

The abs and traction control light is on and chimes non stop and my cruise control will not work when the abs and traction control is defective.It needs the abs pump replaced as do many of these trucks. The next issue is the computer sceen is delaminated and is wanting you to adjust the time and chimes non stop, so it will not allow you to turn on your defrosters so you can see the road. This truck is so unsafe it now just sits in my barn while I drive my 2005 ram with 210000 mile on it! The repair cost is around 5000,00 for a truck with 48,000 miles on it! All safty issues!

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 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.

I have been having intermittent ABS/traction control lights flashing on my dash. When I hooked my truck up to my DTC code reader, it says I have a C0020-21 stored. ABS pump motorcontrol - general electrical failure. I have noticed thousands of complaints on various websites about the same issue. My truck only has 38,000 miles on it. This must be a defective part.....I called and asked my local dealership about this and they said its a very common issue. I believe it is a safety issue because it reduces the trucks ability to stop quickly, it may cause my truck to swerve in an emergency stop situation, and if this happens while the cruise control is on it turns the cruise control off unexpectedly. This happened to me in a bad rainstorm and caused my truck to swerve into the next lane over. I asked the dealer when they could get to repairing it and thy told me it would be months before they could repair it and it would cost approximately 1,800 dollars. They told me to just keep driving it with the error codes active. This is ridiculous. This part needs to be recalled because it affects thousands of vehicles and it is unsafe. My vehicle is available for inspection.

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.

While driving and sometimes sitting still, the Service Antilock Brake System warning will flash on and off rapidly. Then go off. When this happens cruse control stops working. Antilock brake functions no longer work. And traction control no longer works. I found this out while driving on snow and ice covered roads recently. I was stopping at an intersection, and the ABS system started to work then turned off and my tires locked up, causing me to slide into the intersection. Fortunately no one else was at the intersection. Online forums show a great number of low mileage Ram trucks like mine with this issue. Seems to be a failure of the motors on the hydraulic control unit.

Constant warning to service electronic braking system kicks out cruise control. According to ram this is a known problem with related module

- Oxford, MS, USA

Abs and tc lights come on and ding randomly, freedom service told me it-??s a hydraulic pump and causes a safety issue it also knocks cruise control off when it happens. The dealership said they have changed many so I am sure ram is aware of this issue.

- Denison , TX, USA

the service abs and service traction control come on if i hit any bump on the road, seems to be a common problem with this vehicle model.

- Batson, TX, USA

I have a 2018 Ram 2500 with 24320 miles on it. The traction control light/ ABS/ebs service lights come on when driving. The speed control goes off. I have seen on the Ram forum that this is common on this and the 2017 years too. My question is if there are several 100 people with the same problem. Why have you not issued a recall. This will get someon killed if they are not careful.

The touch screen on the central control computer/entertainment/cell phone system has delaminates and randomly self selects buttons. On more than one occasion the distraction of cancelling phone calls at all hours, activation of back up cameras and signals that tell the vehicle to do wierd things negatively impact of drivers attention and function' there are laws about distract4D driving and this is a major distraction. I have tried to resolve the issue with the manufacturer and they are un responsive. Looking at the videos on how to re-lace the touch screen due to manufacturer requesting over $1500 to replace based on false claims of broken/cracked glass in the screen. When the real issue is the touch screen manufacturer failed to use an adhesive that can withstand the heat within the closed cabin of a stationary vehicle.

- Slidell, LA, USA

Loss of throttle from dead stop and while at varying speeds, vehicle is not throwing any codes. Dealer is stumped and has sent me away in a truck that could cause a serious accident. Ive filed a complaint with Ram trucks/Chrysler Fiat but not getting much traction.
