2018 RAM 2500 Electrical System Problems

Abs lights are coming on and off I took to a shop where they told me it's known problem and parts are on backorder

Service electronic braking system message, ABS light and traction control light are on. Code:C0020-0. ABS HPU problem. This is an obvious issue with these year make and model of trucks.

The abs and traction control lights stay illuminated on dash. No abs, traction control, or cruise control. Abs module looks to be the problem

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.

ABS light comes on screen along with traction control. Immediate loss of cruise control while traveling 70 MPH pulling 10,000 lbs on a highway. If brakes go on that everyone's safety on the road is at risk. I have not had it to dealer but have had a mechanic put his code reader on it. Warning lamps for this were the ABS light and traction control light.

ABS and Tracton control

my vehicle and hundreds of other owners are having bad HCU/ABS units that turn OFF the ABS and traction control on our ram 2500's.

Abs/ traction control light comes on and off lose all cruise control. Get code c0020-1.

At around 50,000 miles the ABS light started coming on. This affects traction control and speed control. Dealer said it was the ABS Control Module and is a known issue but not a recall. Finally repaired at my cost of $ 1,103.32. st 57,377 miles on 9/13/2022. Less than 12 months later it is doing it again on 7/29/2023 at 69,649 Miles. This seems to be hazard as the ABS does not work or traction control. Also cuts off the cruise control when it occurs.

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.

Intermittent Abs Failure. Kicks off cruise control and looses ABS brakes and traction control. Very dangerous. Lost this ability while pulling my RV Camper on wet roads. Went into other on coming lane do to sliding and skidding. I guess this is a very well known issues with no recall or information from Mopar\ Ram to the owners. This almost killed me My wife and my 3 year old grandson.

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.

Vehicles touch screen becomes unresponsive to touch and skips around screen turning items and censors on and off while driving. Seat heaters have turned on and off on boiling hot days, radio stations switch back and forth, volume has gone up and down, parking censors have been turned on and off while driving, radio has called random numbers and people while driving and while waiting for truck to prime and start. The problem has progressively gotten worse and skips around more with every day that passes. Vehicle has been to the dealership twice for this issue. The dealership said it has become a common problem with the touch screen for this vehicle and doesn't know why it's not a recall. This is a huge distraction and $1800 replacement which is not an easy random add to a budget, meaning most will deal with the distracted driving and probably cause and...

Message comes up to "Service electronic braking system." Code found was C0020-01 (ABS pump motor failure). Couldn't order part due to engineering review. Truck only has 20,400 miles. This part cannot be worn out. Should be a safety recall.

ABS Module and HCU Failure. No ABS or Traction control which could cause the driver to lose control of the vehicle. There have been several complaints filed but no recall issued. The same part (same part numbers)was recalled for 2019 and newer trucks.Service brake and traction control system lights on. Parts on extended back order.

Driving, hit 40,5xx miles and ABS and traction control light was flickering on and off. Kept getting warnings to service ABS and Electronic Brake System. After 25 miles of on and off flickering and chimes which were extremely distracting, it turned on and stayed on permanently. I do not have ABS, Traction control or cruise control. This is a known issue with the 2017/2018 models, and Mopar does not cover it even though it should be a recall. Thousands of people are having this issue, and dumping thousands into it all for it to just break again in 10/20k miles. The ABS modules are complete junk

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.

ABS hydraulic control unit failed. less than 25k on vehicle. dash message to service and ABS and traction lights as well. bumps and hard braking seemed to cause this to happen, but originally happened as driving as normal. vehicle was rendered uninspectable by dealership and part was ordered . called chrysler and was told this is a known problem without a recall at this time.

As of 07/10/2023 vehicle Display saying "service electronic braking system" and "service ABS" intermittently. Vehicle is available for inspection. Vehicle has 46000 miles on odometer. upon further research this is a very common problem involving the need to replace the ABS module and HCU to fix the issue. there is a class action lawsuit on this matter. Estimated repair cost is $1700. Failure of these components can cause injury or death. Vehicle is not recommended to be driven with these component failures.

Truck has 67,000 miles and is currently at the dealership for the 3rd time with hydraulic control unit and antilock brake system modules needing to be replaced. Service ABS and service electronic braking system lights constantly blink and alarm is chiming. Dealership says part is on backorder with no ETA.

ABS lights flash on the dash, electronic braking system fault, traction control flashing. Intermittent. Research shows replacing HCU will resolve, I will order the part and repair myself but this should be a covered recall since it is a safety concern.

Reporting back-up camera glitches and/or blanking mirror screen! This can cause serious damage or injury to persons or property and even fatalities.

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...

Abs and traction control lights intermittently on and off as well as service abs system message. Had the vehicle scanned and code C0020-1 “abs pump motor control” was identified. After a lot of research this exact problem is being reported by many others with the same year and model caused by a faulty hydraulic control unit and module. Please help us resolve this known safety issue.

I've been dealing with the ABS light going on & off with alarm constantly chiming for almost 2 years now. The anti lock breaking is compromised as is my cruise control. I can no longer operate the vehicle safely and I've had to park my truck permanently, which has created many economic and logistical issues for me and my family. I work 60+ a week to support a 2 and 4 year old child. The abs modulator and hydraulic unit need to be replaced according to the dealership (Ferman Dodge, Holiday, Florida) and (2) other non-dealer mechanics (Hilton Automotive, Ocala and Tuffy Spring Hill) have stated the same when I sought a 2nd and 3rd opinion. I don't understand why there's not a recall? Please, advise to the steps the NHTSA is taking to resolve this ongoing issue. I'm still waiting on the part/ parts to become available and I've...

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, the ABS, traction control, and cruise control intermittently failed to operate with the warning lights illuminated. The contact took the vehicle to an independent mechanic and was informed that the ABS module was defective and needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 66,520.

ABS Hydraulic Control Unit C0020-01 ABS Pump Motor Control Has been in for repair once and diagnositc 2nd time. Awaiting parts. Anti-Lock Brake System Warning Light, Traction Control Warning Light, Service Electronic Brake System Message - Continuous Lit and Intermittent Chime

Braking power was diminished. ABS and Traction Control lights illuminated on dashboard and did not go out.

For about 8 months, our 2018 Dodge Ram 2500 has had interment ABS and HCU warning lights and the notification to "Service electronic braking system" followed by "Service antilock brake system". This may occur for a period of hours or seconds and disables our trucks ABS, traction control, cruise control and other systems. When checked, the truck has no stored fault codes. When this first occurred, I went to the dealer where the truck was purchased and inquired about replacement ABS and HCU modules and was informed that none were available. After subsequent visits and internet research, I found TSB#C0020-01, "ABS Pump Motor", that directs replacement of the ABS/HCU modules, and directs that the replacement parts will be provided by a "STAR system". We have had three incidents that we narrowly avoided accidents, two due to the intermittent ABS failure and one due to sudden loss of traction control while...

HCU / ABS module issues. Truck while driving has no cruise control my lights stay illuminated all the time, truck only has 57,000 miles and already repaired all 4 abs wheel speed censors, spent countless hours visibly checking all wires and fuses make sure no defects there. This could be a very dangerous and life threatening situation and I would think it's only right for Dodge Ram to recall the 2017-2018 for this ABS issue.

ABS ESC constantly flashes and chimes non stop…. Failed control to wheels in wet weather conditions/ no cruise control/ 4x4

The Anti-Lock Brake control module along with the Hydraulic control unit is failing. At any rate of speed, the traction control light and the ABS light comes on and off repeatedly. When this happens, the cruise control disengages which has cause the truck to slow down rapidly in heavy traffic causing other drivers to almost rear end my pregnant wife, 3 year old son and I. I had my local ram dealer pull the Diagnostic Trouble Codes and confirmed that the parts stated above, were in fact failing. The messages that pop up on the instrument cluster are “Service Anti-Lock Brake system” and “Service Electronic Brake System”. I can not have this component inspected as it is a daily driver and is the only vehicle we have currently.

track control and abs light on and no cruise control working

The ABS, traction control, cruise control and 4x4 no longer function. It started intermittently and now is constant. The vehicle is available for inspection. After a hard stop the abs won’t engage and I lost traction of the truck. There are two warning lamps that are on at all times (abs and traction control). It has been ongoing for almost 1 year and 10,000 miles or so.

Radio will show back up camera when driving, call cops,call people, turn the station, turs the heat up and A/C on and offd

Driving down the highway with the cruise control set and all of a sudden the cruise control stops working and my dash is dinging with service ABS system and service Electronic Brake System. The truck had 78,500 miles when this first happened. Now it does it intermittently while driving down the road. I notice there’s no recalls and it sound like a large problem. Haven’t taken it to a dealer yet.

ABS Control Module defective at 40,000 miles. OBD scanner confirmed issue. Warning lights and dinger sporadically on and off.

At 36,000 miles have been told I need to replace ABS pump control general electrical failure. Also replace ABS module. Parts are not available and are on backorder. I pull a 25 foot camper and this issue is causing concern with vehicle stopping. Apparently is a big problem as parts are not available and dealers that have part will not release parts so my truck can be fixed.

ABS LIGHT AND TRACK CONTROL IS ON AND THE TRUCK IS NOT GETTING TRACTION TO THE GROUND AND MY CRUISE CONTROL IS NOT WORKING WITH THE LIGHT ON.

ABS module system has been replaced twice .. needs to be replaced again per Dodge tech. No parts available. Unsafe to drive vehicle with no power brakes This is not unique to my truck. various individuals having same problem with same model Electrical Instrument cluster with display has been replaced and currently working.

On my way to work one day the check engine light,ABS light and traction control light came on and I thought something under the hood had came loose thought nothing about it and went into work when I came back out and got into the truck the lights where gone no big deal just sorta let it go and since I work out of state this is the truck I drive when I go back to my home state so I drove it 4 hours one way and never had a problem and then on my way back to my work state the truck shut off and wouldn’t start back up for about 45 minutes or so but when it did it had a red lightning bolt,ABS,traction control and check engine light on so I called the dealership and asked them to check on it but by the time they...

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.

I purchased my 2018 Ram 2500 mega cab from Grieco Ford in Delray Beach 4 days ago. As I was driving home, the ABS service, electric braking system and anti lock braking service lights came on. Took it to New Smyrna Beach Jeep Dodge Ram, they plugged it in and said the HCU needed replaced and was it n back order until September. I don’t know what to do.

Received Code: C0020

Intermittent ABS, EBS and traction control issues causing spurious warnings and loss of cruse control. The alerts are distracting to the driver, loss of ebs/abs represents safety issues while traveling, as does the loss of traction control and cruse control. Dealer has diagnosed the issue to the respective abs/ebs controllers but reports no parts in inventory and no due date for when they will be available. Formally request NHTSA force a recall to require the mfg to correct the issue expeditiously.

The vehicle experiences intermittent fault displays for "electronic brake service" and "ABS Service". This causes the vehicle to suddenly come out of cruise control and slow dramatically. This causes the vehicles ABS safety function to be inoperative reducing the overall braking capability and increasing the safe stopping distance This causes traction and stability controls to be disabled further degrading the built in safety features This was diagnosed several months ago by the dealership as an ABS hydraulic pump problem with no parts availability. The lack of parts has been an issue for months and has rendered my vehicle inoperative. The dealer said this was a common problem and that they had multiple Ram trucks with the same problem. I also checked online and found multiple reports of the same issue across the brand and across the country. This is a significant and costly repair >$800 for a part which is...

Anti-lock brake system/ hydraulic control unit has been out for over a year. Paid dealer for part, that is on back order, have to continue to drive vehicle and have no idea when it can be fixed. The lights and alarm continuously go off making it incredibly unsafe to drive because they NEVER turn off and are totally random. I’ve been tolerating this for over a year and was told to file a complaint because many others are dealing with the same.

I HAVE BEEN EXPERIENCING ISSUES WITH THE ABS/HCU UNITS. THE WARNING COMES ON EVERY BUMP AND THE ABS SAYS IT IS NOT WORKING I HAD IT SERVICED LAST WEEK 4/18/2023 AND DIAGNOSED AS THE ABS/HCU NEEDS REPLACED AND WAS ORDERED. UNFORTUNATLEY THIS IS ON BO UNTIL 8/16/2023. I UNDERTAND THE 2019'S HAD A RECALL BUT MY 2018 DOES NOT?

ABS, TRACTION CONTROL, REPAIR ELECTRONIC BRAKE ALERTS HAVE BEEN FLASHING WITH AUDIBLE BEEPING AND AT TIMES REMAINS LIT WITHOUT BEEPING. Putting a load on the engine or hitting bumps on road seems to cause the warning lights and beeping. This has been going on since June of 2022. Vehicle was taken to shop and diagnosed with failing part (electronic abs brake module) Part was not readily available and waited two months for part for repair. Cost $525.00 total. Did not fix problem now repair shop states the truck needs HCU hydraulic brake fluid pump. Its been EIGHT MONTHS no part available. Truck is in need of repair, no parts available and has limited our use of airstream tow vehicle for travel.

ABS and HCU are in need of replacement parts. Because no replacement parts are available, I have no choice but to drive a Truck with questionable Breaking System, putting me, my family and others at risk, since the brake system is what stops my Truck when I need it to stop or slow down. I use this to tow the family travel trailer as well. This is also very important when brakes are needed to function safely. I have taken the Truck to my dealer of purchase. They completed a diagnostic test and also reproduced and confirmed the problem. The vehicle has been inspected by the manufacturer's dealership Service Dept. The Truck's "ABS SERVICE BRAKE SYSTEM" warning lights and warning tones alerted me of service needed back in November 2022, with just over 36,000 miles. I made an appointment and the dealership serviced my truck in January 2023. Since no...
