2018 Ram 2500 ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,SERVICE BRAKES

Service abs system immediately popped up on information screen, also abs and traction control lights all at the same time. This disengages cruise control and removes digital speed reading. Almost got tailgated.

Traction control and abs warning lights flash on and off intermittently also cruise control not working when this happens. It is sporadic

ABS module or HCU bad. Anti lock brakes not working. Cruise control not working. 4WD not working. Caused issue driving with a load when ABS did not engage and almost rear ended another vehicle.

Intermittent ABS and traction control lights. Service lights come on and go off when braking or driving over bumps. Code C0020 - ABS Pump Motor Control General Electric Failure. Issue is so random I haven’t taken the truck to a service center.

I keep getting warning lights for ABS problems. Saw there was recalls for the 2019-2022 and saw there was a class action law suit for the 2018 models.

Continued failure of hydraulic control unit (HCU) and Anti-lock brake system (ABS) module causing fluctuations in brakes at times (have to press harder on brakes) and lights go on and off, sometimes staying on for lengthy periods (usually on highway) or while driving and disables the cruise control. Second time in just under 3 years (fixed in Nov 2020 and reported to dealer Sept 2023), same issue on parts both time, fix identified as faulty HCU and ABS module as dealer identified issue and placed order for parts (5 month backorder to Feb 2024 as apparently very common issue with these trucks). The issue is both the change in brake sensitivity due to this part failure and the sudden cancellation of cruise control, the braking impacts the braking performance and cruise control drop out causing sudden drop in speed on highways.

Whenever it rains or is high humidity, my dashboard lights up and repeatedly chimes with ABS lights and Electronic Braking System error. The error repeats itself on and off again every few seconds. It is a dangerous distraction of error messages. Since it is raining, all traction control and ABS systems deactivate themselves with this error. I spun out this morning due to the error. It is absolutely dangerous. This is the EXACT error that occurred on my previous Ram. This is a dangerous faulty hydraulic control unit (and ABS system). Upon a little research, I found tens of thousands of posts of owners being stranded or driving without ABS / traction control due to this malfunction. This is deadly and needs to be recalled. RAM is aware of this issue but has not issued a recall. It is raining today, and my RAM will not have traction control or ABS. This is unacceptable. This is affecting tens of thousands of owners. With upwards of $1,600 for a repair. Yet, the part can create a fault AGAIN within weeks or months. DANGEROUS.

Hydralic control unit is bad causing on dash safety alert for service electronic brake system alert and anti lock brake system alert. When towing will not have brakes to assist in stopping tow vehicle. The alarm constantly going off distract your attention from the road. Upon going to the dealer for repairs I was told they are on national back order and may not be available until after the 1st of the year. It apparently a widespread issue with all 2017 and 2018 Ram 2500s. I am unable to tow my 38' 5th wheel camper for fear I will lose my brakes on the tow vehicle putting myself and others at risk. The anti lock brakes not functioning properly could result in losing control of the vehicle when road conditions are wet or slippery. This loss of traction put me and other motorist at risk. Ram know there is a problem with the HCU. My understanding is they have had to completely re-engineer the part and as such has created an availability problem for anyone owning these vehicles. There are several blogs and forums online describing this as well as a class action suit initiated by the state of California. Would appreciate you looking into this matter and getting Ram to do the right thing. Thank You

While applying the breaks the vehicle will deactivate ABS and force the vehicle to slide without control. ABS will turn off and on without warning. While using cruse control abs will deactivate and cause cruse control to stop working, causing the vehicle to slow unexpectedly. This has happed while towing a goose neck trailer causing additional pressure on vehicle when sudden loss of cruise control and abs.

ABS HCU/and pump failure. Truck dies. no Brakes

The ABS light came on and went off intermittently, which also disabled the cruise control when the light was on. Eventually the light stayed on. Most recently the start button quit working properly. We have had it at the dealership twice with no results. We have talked to the dealership many times and been getting the run around. The latest was today and was told the parts are back ordered until 2024. They have not given us any paperwork because we do not have to pay. We also have and had the radio (main computer) replaced a couple of times and the screen still blinks randomly.

ABS/traction control sensor issue. I believe it to be a faulty sensor or sensor connection issue which is causing my service brake light to chime and light up at every bump in the road. While driving even just a short distance my service brake light/alert chime goes on and off sometimes every 2-3 seconds and while driving on the freeway my cruise control disengages every time the brake warning pops up. Upon researching this issue I've found thousands of Dodge Ram owners complaining of the exact same issues and dealerships are suggesting they know nothing about this problem.

the abs module and the hydraulic pump have a issue that turns on the abs and light and turns off the cruise control and reverts to non abs braking due to faulty module and pump assembly that was changed already and now the wont cover this under any warrenty known faulty part

C0020-01. Electronic Braking System and stability control system continually go in and out of alarm kicking the truck out of cruise control suddenly. This was repaired once under warranty by replacing the hydraulic control unit at 40,000 miles and it is now doing the same thing again at 90,000 miles. This is a significant safety issue as it prevents the use of cruise control and turns off the stability control system on the truck. The parts to repair the system are not available due to them being in “Engineering Review” until 2024. The only guidance from Ram was to continue driving the vehicle until parts become available.

ABS TRACTION CONTROL BRAKING ISSUES AND DANGER. ONLY HAS 24K MILES GARAGE KEPT

My ABS and Traction control lights activated visually and with audible alarms. I brought it to the dealer. It only has 23,000 miles on it with a manufacturer extended warranty. The dealer told me that the ABS pump motor control as well as the HCU has failed and need to be replaced. They also told me that the parts are not going to be available until the EARLIEST February of 2024. The vehicle is not safe to drive without these safety systems working especially towing. They told me the parts are under Engineering review. They suggested I park the vehicle until parts are available. NOT ACCEPTABLE!!! I have looked at owner forums and this issue is common and needs to be addressed by NHTSA and the vehicles recalled due to safety.

My ABS / Electronic Stability control warning lights keep coming on intermittently and also sometimes staying on for hours at a time. I cannot use my cruise and my ABS will not work with these problems making this a very dangerous truck to drive. I have read that there are many other trucks with this issue. More specficially the 2017-2018 Ram 2500's. I believe there should be a recall for these parts as this is a intergral function in these HD trucks.

C0020-01 code began coming in and out immediatly following a service at my local Ram dealer. I returned to the dealer after the warning lamps and messages all came in around ten times within a mile of picking my truck up from them. The dealer used a device to clear the messages, but the alarms returned again after I left. There are multiple warning lamps and messages that remain in as a result of this: service anti-lock braking system, ABS warning lamp, traction control lamp, and a loss of cruise control functionality. While the constant "dinging" sound and loss of cruise control on a truck with less than 20K miles is disappointing, I am concerned whether or not these warnings are indication of a serious safety hazard to my family and/or those we are on the highway with. My truck is available for inspection. The issue was confirmed by my local dealer who cleared the alarms when they first came in.

The abs pump and module are bad and there is no replacement parts available through ram. The truck only has 32k miles. They say the parts are on back order. The truck has no abs function nor does it have vehicle traction control. This should be a recall as it’s happening to thousands of trucks. This is a blatant safety violation. Yet the new trucks are still being built with these parts that are somehow not available.

My 2018 Ram 2500 6.4l is experiencing intermittent ABS, traction control, electric braking warnings on the dash which affects cruise control once alarm is active. This issue seems to be globally.

Hello, I have been having issues with my 2018 Ram 2500. The Service Traction Control and ABS lights on the dash have been flashing on and off constantly. Along with no Cruise Control when this happens. This has been going on now for about 3500 miles. I am still driving the vehicle due to being my only work truck. I have been doing some research along with talking to the Ram Service Departments and have noticed that this is a very large safety problem that is highly known about that is not being taken care of. Even the service manager I had spoken with is amazed that this has not been a recall. This should most definitely be a recall and should be taken care of before more people get injured or killed.

Service ABS light comes off and on sporadically. This is a known problem through out the country and needs to be addressed by a recall.

Similar to the 2019 & newer Ram HD recall for the ABS electronic control module, my 2018 Ram 2500 has the same issue. It was recently diagnosed at the dealer in August 2023, but due to the abundance of impacted trucks, the dealer estimates that replacement parts will not be available until at least February 2024. While I wait for the repair I have no ABS, traction control, stability control, or cruise control. I drive the truck approximately 750 to 1,000 miles per week and have a 3,000 mile vacation planned in October. This translates to driving the truck approximately 15,000 to 20,000 miles without the above noted safety features. I believe my truck should be added to the recall, and RAM needs to step up and provide faster repairs.

Faults for the ABS (anti-lock brake system) and EBS (electronic braking system) have been coming on intermittently for a couple months. Now the faults are permanently on indicating the ABS and EBS needs serviced. The fault code is c0020-01which indicates the known malfunction involving the anti lock brake system module and anti lock brake system control. While these faults are present the cruise control also doesn’t work. This is a well documented and known issue with certain model years Ram 2500 and 3500. My truck had approximately 57,000 miles when the faults began.

Consistent and predictive Failure of Anti-lock brake control module (68143491-AA /68143491-AB) in 2018 Ram 2500/3500 Trucks. Nationwide shortage of OEM Replacement Parts leading dealers to hoard exclusively for customers for whom repairs are to be made. Extremely difficult to find a dealer willing to sell brake control module, if they have one in stock, to anyone. Instead, dealers recognize there is up to a 6 month waiting period for restocking and therefore taking advantage of those who chose to utilize independent mechanics. Dodge/Ram is acutely aware of shortage, as well as failure of part and has chosen to not warranty or conduct a voluntary recall. Every Ram mechanic and parts office I spoke with acknowledge EVERY 2018 Ram 2500/3500 will fail. The subject vehicle had under 31,000 miles. During failure, the vehicle loses its' anti-lock functions, traction control, defeats cruise control, dash continually lights up with error message 'SERVICE ELECTRONIC BRAKING SYSTEM' then 'SERVICE ANTILOCK BRAKE SYSTEM' while simultaneously and constantly generating an audible warning over and over again during the operation of the vehicle. Price gouging for part, if you can find a dealer that 1) has the part in stock, and 2) willing to sell the part can run between $180.26 - $525.02 (MSRP $262.00). Part is in use for year models 2012-2018. I personally paid $525.02 (and grateful a dealer sold the part to me over the objections of the parts manager), drove 4 hours to obtain, plus install.
