2018 Ram 2500 complaints

Service abs system light is on as well as service electronic braking system. My truck no longer has antilock brakes. Cruise control does not work. Dealers do not have parts available to fix the issue. This is a very common and well documented issue with these trucks. This was an intermittent problem to begin with but is now permanent. They should be recalled.

Hydraulic control unit was replaced July 2020 (ABS traction control lights coming on MEANING, NO ABS NO TRACTION NO 4 WHEEL DRIVE.) Hydraulic control Unit not working AGAIN. I have NO ABS, NO TRACTION, NO 4 WHEEL DRIVE, AGAIN. CHIME GOING OF CONSTANTLY AND DEALERSHIP HAS HAD "PART ON ORDER SINCE JAN 2023"

HCU, ABS Modules. Inspection Is Available Apon Request. Concern For Safety With Hard Brake Pedal, Not Stopping As Required. Modules Do Not Respond To Hard Braking Like Described. Speedometer Not Reading. I Changed The Cables To The Wheel Hub With Still No Response. 42,600 miles In It, No Accidents. Problem Started 8mo. Have Not Driven For 3mo Now. Safety Not Confident. No Dealer, Mechanics Only A An Advanced Code Reader Scanner. Engine Light, ABS, Car/Lane Symbol Display.

Abs and traction control light, warning comes on and off and says service system

Truck throws ABS and Traction control warning codes intermittently and when hitting bumps. On a six hour trip today it threw the codes 50-60 times. Worried this could cause serious accidents if features do not work as they should.

ABS module/ HCU. Abs light & traction control light is on. Was driving down the road when they lights started flashing. Have been waiting for parts for 4 months because its on national backorder.

Abs light comes on turns off cruise and traction control, brakes becomes spongy and vehicle gets pushed through refle light bey trailer. Near miss accident.

Abs and traction control lights are illumated when towing a trailer it would turn off trailer breaks I have taken it to auto shops and they state its the abs module or hydraulic control unit. When normally driven abs will be intermittent and can pose a safety hazard.

ABS warning to service anti-lock brakes. Mechanical brakes continue to function. The ABS system continually warns and chimes about the electronic ABS system not working. The ABS fault code is C0020. A Chrysler/Ram dealer has attempted to repair it once.

ABS light and Traction control lights go on and off constantly. Issue started around 38,xxx miles. This is a known issue in the ram community and Chrysler needs to recall these trucks to make the proper repairs to the HCU and ABS module. This is a major distraction while driving as the lights and chimes constantly go on and off and I cannot focus on the road. when these lights come on the ABS system is disabled, all traction control is disabled as well as my cruise control.

Abs braking system has been flashing and traction control light flashing. My left front wheel started grinding and smoking out of the blue when driving today. No problems with brakes before that. Cruise control doesn’t work. And four wheel drive service light is flashing again!! The four wheel drive sensor was replaced once already a couple years ago.

Our truck has the AB HCU module light showing with a problem.Constant dinging while trying to drive. The part has been on backorder from the local Ram dealership since October 2022. We have been told that it's a known problem with Ram diesel pickup trucks. Please help by providing a recall. This is ridiculous on a truck with less than 45k miles.

Was driving vehicle on a rock road, when rounding a slight curve in the road, the antilock brake system light and the traction control lights both illuminated at the same time. The rear end of the truck began to slide due to having light pressure on the brakes and I was pulling my fifth wheel camper. Fortunately there were no injuries or damage to the truck or the camper. I washed off the mud when I got back to a hard surface area that had a car wash available and continued on my journey. Approximately 30 more miles later on the same trip both warning lights came on again. I immediately pulled over to read the message warning that was up on the dash to see if I could continue with my journey or not. After reading the message on the display in the truck, I decided it would be safer not to continue with my journey with that truck due to the safety issues and possibility of injury or death to me and my passengers, or another vehicle that I may encounter either head on or from behind. I had a friend of mine bring his fifth wheel truck to pick up my camper and return it back to my home. I had to cancel my camping trip for that week, which cost me approximately $400 out of pocket and then I had to pay my friend gas money to bring my vehicle home for me. I placed a call to the dealership nearest me and they advised me it would be $1,000 to begin any sort of diagnostic procedure on the I have now been driving the vehicle only unladened with any sort of extra payload, the light will c

Service Lights on dash. Service Antilock brake system, SERVICE electronic braking system. Defective part is HCU, hydraulic control unit. Part has been unavailable for over a year and part availability always pushed back on estimated arrival date. This safety issue needs to be addressed with a recall.

The ABS failed while on hwy. Researched, and break loss is a common problem in this gen pickup.

At 9955 miles, the WARNING CHIMES were activated on this vehicle, and the error message on the dash indicated 'ABS FAILURE' and/or 'SERVICE ABS SYSTEM'. I checked the OBDII codes and saw code C0020, 'ABS pump failure and/or Hydraulic Control Unit Failure'. Took vehicle to the stealership, who also checked the OBDII scan and replaced both the pump and the HCU with the SAME SUBSTANDARD COMPONENTS that were previously used. Less than 6000 miles later, the SAME PROBLEM BEGAN OCCURRING AGAIN, along with the SAME OBDII failure code. Took vehicle back to stealership, who confirmed that this was the SAME PROBLEM that occurred at 9955 miles, but that they couldn't order the 'new and improved' parts from FCA until Jan, 2023. Returned to stealership in March, 2023, and was told these ABS parts were now on backorder. Filed a complaint with FCA Customer Care, who then sent the 'backordered' parts to the stealership two weeks later. The stealership WILL NOT INSTALL THE PARTS UNLESS I PAY FOR THE PARTS AND LABOR in spite of a RAM TSB describing this failure and a Texas class action lawsuit against FCA for failing to address these ABS safety problems affecting thousands of RAM HD truck owners. FCA still has not issued a recall on the faulty ABS components. EVERY TIME THE ABS WARNING CHIME OCCURS (OFTEN EVERY 10-15 SECONDS), IT DISTRACTS THE DRIVER AND CANCELS THE CRUISE CONTROL, AND, OF COURSE, THE ABS SYSTEM STOPS FUNCTIONING.

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 trailer brakes traction control works on and off

2018 Ram 2500 Diesel Antilock Braking System light Traction control light Park sensor warning 4 wheel drive unavailable light All issues are intermittent. Issue seems to be a reoccurring issue according to my research. Vehicle has not been inspected but has had codes scanned when the issue occurred. I feel with the brakes being at an intermittent state it puts myself and others on the roads at Rick if they were to stop working with no indication.

There seems to be a huge ongoing problem with ABS pumps and control modules for this model vehicle. I can find pages and pages of issues online for the same truck. The 'service brakes' warning comes on and off intermittently and I managed to replicate the fault after several months long enough to get it diagnosed. I am told the following parts are the issue: 68347098 - AB MODULE AN 08035030 68143491- AB CONTROL A 08035030 I got the truck diagnosed in January but was initially told Mid March for the parts and now am being told August - which would mean no functioning ABS on my vehicle for 8 months! And no guarantee the delivery date won't creep again. This is unacceptable for a safety critical component and clearly shows a fundamental flaw with the parts as they can't seem to make them faster than they are failing. I can find many reports of these happening from as early as 14,000 miles and with the replacement parts also failing.

ABS traction control warning comes on intermittently. This causes cruse control to disengage intermittently, and causes braking and traction to be compromised at times

RAM has a “known issue” with the ABS system, mainly the Hydraulic Control Unit, with the brake systems in at least the 2018 model year heavy duty trucks. They redesigned part number 68143491AA and released a new version, 68143491AB. However this part has been back ordered. I have waited 3 months so far, and have been told earliest to expect the part is August 2023. Others have waited more than a year already. Without the part, the truck rapidly flashes warnings on the dash. Additionally, the ABS, traction control and stability control systems are inoperable. For a 10,000 lb GVW truck with 800+ lb/ft of torque, this makes for dangerous handling for wet roads. I don’t need anything for free, but something should be done to make RAM accountable for the dangerous situation they are forcing on the owners of their vehicles. These parts need to be manufactured quicker and made available for purchase by effected customers ASAP.

ABS pump motor control general electric failure found by dealer code C0020-01 per dealer needs hydraulic control unit. Warning comes on ABS unit need service. Safety concern braking system could fail. Mileage at time of dealer diagnostic 28572 keeps reoccurring current mileage 29791

My ABS light has been intermittently illuminating my dashboard since December. I took my truck to the dealer on 3/13/23 and it's still there. Per the dealer, it needs an ABS module and the Hydraulic Control Unit. I had already replaced the HCU over a year ago so thankfully it will be covered by the dealer, but the ABS module still needs to be replaced and was told that the HCU won't be available until August. Dodge needs to address this. Obviously, this is an ongoing issue and it's not safe to drive and puts myself, my family, and others in potential danger if the electric brakes aren't performing properly. Also, I was advised by the dealer that the ABS module going out has caused the HCU to go out and is an ongoing issue that they have been seeing with no known cause.

ABS has been a non-stop issue on this truck since purchase. It has been "fixed" 3 times and currently is not drivable due to no ABS, traction control, cruise, or 4 wheel drive available. aBS module is on backorder for 3 months.

ABS Control Module failed and was replaced with part #68143491AB. Truck was purchased for plowing. Without anti-lock breaks and traction control, myself and passengers were at risk , and my ability to plow more than a few inches of snow was nearly impossible. Living on a dead end private road, plowing for neighbors to access main roads was not possible, putting neighbors and family at risk during winter emergencies. The part was back ordered for several months, delaying the repair and extending risks. The vehicle did provide an alarm to audio alarm of this problem which was a distraction throughout the part backlog period. The cost of the repair to me was $1, 119.95. This should not have occurred on this truck that had less than 40,000 miles.

Have taken the vehicle into Dodge / Ram Dealership twice within 90 days and steering issue remains an issue. I have been charged over $2000 for replacement parts and labor to include a new Drag Link. Was driving on the highway on 12 March at 1430, when truck began to drift to the right almost striking another vehicle. Vehicle has been a local Dodge Dealership and they have left me leave 2x putting my family, other drivers and myself at risk.

The ABS system warning lights have come on and system not working, had it checked and was told it was the ABS controller assembly pump motor, code # C0020-01, and that it was a common problem with this vehicle. I was told i should report it.

My 2018 Dodge Ram 2500 has a known faulty issue with the HCU/ABS (hydraulic control unit/Anti-Brake System). My ABS light continues to flash while driving. This problem is very well known with 2017-2018 RAM trucks. The local dealership stated that the part is on backorder till August. This will be $1,000.00 + fix from dealership. This has been an ongoing issue, not just myself but many RAM owners, that happens at various times. The issue occurs at various speeds, when I hit a bump, or when I hit the brakes. This issue needs to be resolved with Dodge Ram and a recall issued.

The anti lock brake system module failed in September of 2022 and Ram is still unable to provide a replacement part. The brakes lock and the truck slides easily when pulling a trailer in rain. This is a VERY common problem and should be addressed by a recall.

My ABS and Traction Control fault lights came on in my dash. I was towing a camper that weighs approximately 10,000lbs. and the trailer brakes did not function while this fault is active. Without the operation of the trailer brakes this is a very dangerous situation to stop that much weight. Had the code checked. Code C0020-01 is what was displayed. While this code is aluminated the trailer brakes do not function.

The Service Electronic Braking and Service Traction Control comes on intermittently while operating the vehicle. I have had it fixed once under warranty. It is not a safe vehicle to operate without traction control and abs.

In November of 2022 I reported to the dealer that the ABS and Electronic Brakes System warning lights were intermittently coming on an off. The dealer diagnosed the problem as a hydraulic brake control module failure, but stated that the part(s) were back ordered until March of 2023. This seems to be a common problem with this model and year of truck, but Chrysler (FSA) has done nothing to resolve this safety issue. It's been 5 months now and I this issue could cause a crash or worse.

ABS light and Tracking control lights flicker on and off constantly. No warnings just came on one day. I have 38,000 miles on my truck not very many for warning lights to come on. I cannot use cruise control as well as about half of my controls. Including tracking control which is now permanently off and is a major hazard! Took it to the dealership in Concord, CA and was told the control module is bad. With no time frame to fix. Probably will be a fix once my warranty is up so the dealership is not liable to fix my truck. A quick search online shows this is a problem for this vehicle.

ABS Traction control turns on and off as truck is driven. Sets code for ABS motor. Called dealer was told to drive until light stayed on.

ABS HCU module was intermittent in 2020, replaced HCU Has been working fine till now. looks like I was sold the old part number. 2 years later it is throwing fault codes again. RAM has an updated part number now. This should be a recall and I shouldn't have to pay to have it replaced for the second time.

Intermittent ABS Service electronic braking system & service antilock brake system

Antilock Braking system warning flashes on and off constantly. Diagnosed as HCU (Hydraulic Control Unit). DTC code is C0020-01 Researched and found RAM TSB S2005000004. Also found that MANY of these have failed. Not only that, but my dealer cannot even order a replacement part until late June 2023 and it is March 4th, 2023 now. Then, when it is ordered, may still take another 3-5 weeks to receive. My point is. This needs to be treated as a recall. Obviously there are major issues with this component, so much so, that you can't even buy one to replace the failed component. In the mean time, I have vehicle without ABS braking.

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.

Message appeared on truck display while driving in a snowstorm, "Service Electronic Braking System". Loss of ABS/EBS control while navigating dangerous roads. Code C0020-01, ABS pump motor control is faulty.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the ABS hydraulic control unit needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that they would assist in expediting the replacement part. The failure mileage was approximately 33,600.

Abs/traction control lights come on and disconnects the cruise control dangerously wen pulling a trailer, code is c0020-01 this is a very common issue with these trucks parts unavailable, I’ve talk to many other owners with same issues please address the problem before someone gets hurt thanks.

The contact owns a 2018 Ram 2500. The contact stated that the ABS warning light intermittently illuminated while driving at various speeds, followed by an audible chime. The contact had taken the vehicle to a dealer where he was informed that the hydraulic control unit (HCU) needed to be replaced. The contact agreed to have to replace the part; however, he was informed that the part was on backorder. The manufacturer was also notified of the failure and the contact was provided a case number. The vehicle was not repaired. The failure mileage was 34,000. The contact stated that the dealer still does not know when the item will be available.

The contact owns a 2018 Ram 2500. The contact stated while driving 5 MPH, the ABS and electronic braking system (EBS) warning lights illuminated. The vehicle was taken to the dealer and the dealer stated that the ABS pump motor needed to be replaced. The vehicle was repaired but the failure reoccurred. The manufacturer was not contacted. The failure mileage was 37,000.

Began receiving a warning message of " service ABS breaking system / service electronic braking system. Contact dealer " while message is displayed, ABS and traction control will not work. Dealer diagnosed as a known issue with a faulty ABS controller and/or hydraulic control unit failure. The dealer said there was no recall even though it's a known issue so the repair is the customers responsibility. The cost of the parts if available, plus the cost of labor is forcing the truck to be operated on daily basis and quite often towing heavy loads in a condition that is extremely unsafe.

The ABS system has failed again on this vehicle. It was repaired by the dealer at 23,836 miles initially. The ABS module is in need of replacement again at approx. 58,000 miles. The ABS and traction warning lamp come on and off intermittently while driving.

Driving along freeway to visit family, cruise control engaged, travelling 65 mph, when all of a sudden several messages flashed on the dash to "check electronic braking system", and traction control disengaged light and service light came on as Cruise control shut off. after a few seconds lights went out and system returned to normal. Repeated several times on way back home (3 hr drive) and had randomly happened since almost every time I drive the truck. Had similar situation a year after I bought the vehicle, 11/2020 @6600 miles, local dealer replaced HCU. This can potentially leave me without Traction control and ABS when I need them and could cause an Accident. I'm waiting for dealer to get other parts in for a covered warranty repair, (Been waiting since Nov 2022), and have them fix both, again, but it renders my truck useless- dangerous to drive until then.

Chrysler issued a recall involving the 2019 to 2022 Ram 2500, the 2019 to 2022 Ram 3500 Chassis Cab with GVWR under 10K lbs., and the 2021 to 2022 Dodge Durango due to an ABS Software issue. They have completely ignored the 2018 RAM pickups with an ABS Controller issue. We have had a part on backorder for months and the dealership we work with has 14 of them on backorder. Research on the internet has confirmed hundreds of other RAM owners of 2018's have the same issue. The ABS warning message and ding goes on excessively. In an hour's drive, it might go off 12 to 15 times, warning the ABS system is not operating. It also causes the Cruise Control to cease working. We need some help on this issue.

At 15,000 miles i had Service ABS, Service Electronic Brake System and warning lights activating at different times/ conditions. When this happened the cruise would also disengage without warning. Brought to the dealer and the ABS control module and pump were replaced under warranty. At 75,000 miles the Service ABS, Service Electronic Brake System and warning lights were activating intermediately at different times/ conditions. Again the cruise would disengage without warning. I had the code checked at it was listed as code C0020-01 "ABS Pump Motor Control- General Electrical Failure." which i believe is the code that was thrown at the 15,000 mile mark. Right now i am waiting for the part to become available for replacement.

The Uconnect display will randomly start rapidly selecting features causing great distraction to the driver and occupants. This includes automatically initiating the SOS call, dialing 911 on Bluetooth connected phones, turning on seat heaters, steering wheel heaters, activating the reverse camera display (the list of things it will do goes on for most of the features), all causing great distraction.
