2018 Ram 3500 complaints

Abs trac control going crazy dealer repaired under warranty about 15k drove approx 2k and same issue no longer under warranty tried to buy parts none available. truck doesn't start correctly when the lights are on and when driving there is a dinging as lights flash on and off.

Related to investigation PE 22-012, abs hyd control module failed truck only has 18,000 miles.

The ABS pump motor was replaced on 10/22/20 at 28,095 covered by warranty. The ABS/ ANTI SKID warning lights came back on at around 58,000 miles. The vehicle was taken to Firkins CDJR in Bradenton, FL for diagnoses confirmation and repair on 04/11/23. I was advised the ABS hydrolic control unit, part # 68143491-AA, needed to be replaced but was unavailable anywhere and it was not going to be available in the foreseeable future. Advised to call customer care who advised me to try a different dealership. I discovered that a replacement control unit, part # 68143491AB, is apparently available at Mopar parts for approximately $350. At this time I don't understand why a CDJR dealership says a part is unavailable that appears to be available on the internet. I pull a 5th wheel and at this time I apparently can't get the ABS system repaired in my 2018 RAM drw diesel with 59,000 miles on it. There was no incident or accident due to ABS system failure. Although the vehicle runs normal I consider this to be a potential safety risk.

The EVIC display showed Service Antilock Braking System and alternated to Service Electronic Brake System. It would constantly bing and display the ABS light and the Traction Control light. Unit failure of antilock braking system and traction control while driving. Problem is intermittent. Ram is aware of issue, but will not honor as warranty. Parts are BQ for months. Problem apprears to be wide spread.

I have two warning messages appearing on my dash. Service Electronic Braking System and Service ABS System. Took it to my dealership Michiana Chrysler Dodge Jeep Ram FIAT in Mishawaka Indiana. I was informed that it needed an HCU (hydraulic control unit) and that the part was unavailable because of engineering review until at least August 2023. The work order was closed and i was sent on my way and told to check back at a later date for availability. After a little reading i found that this issue is under investigation and i wanted add my truck to your list of reports.

Service electronic braking system ABS light. No parts readily available from dealerships 6-8 months for parts and still no contact on parts or a fix.

The contact owns a 2018 Ram 3500. The contact stated while towing a trailer full of horses, the traction control and the ABS warning lights illuminated. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the turbo and the ECU to be replaced. The vehicle was not repaired due to the parts not being available. The contact took the vehicle to another local dealer: Jacksonville Chrysler Dodge Jeep Ram Arlington (9600 Atlantic Blvd, Jacksonville, FL 32225: (877) 677-5782), where it was diagnosed with needing the turbo and the ECU to be replaced. The vehicle was not repaired due to parts not being available. The manufacturer had not been informed of the failure. The failure mileage was approximately 61,000.

Abs brake module problem over 8 months ago, replaced and same problem occurred soon after waiting on parts for several months, parts on back order. Dealer is well aware and also frustrated having several trucks with same issue. Since truck is used for towing heavy loads, Its a dangerous situation still having to use truck for towing, speed control and trailer brakes will not work when abs failure is flashing chimes all the time. Putting extended wear on truck brakes. I'm sure it against DOT rules and will fail my upcoming DOT inspection and not legally able to drive legally. Unfortunately I have another 2018 truck with same issues and this is the most frustrated I have ever been as a ram owner sine 1998.

My vehicle has under 18,000 miles. Driving down the road, the Service Antilock Brake System error light came on and also the Service Electronic Brake System light - they both started coming on and the bell to the light rang. It did this for the next 6 hours of driving (we were on a long trip) - I did research, and it appears to me, this is an ongoing issue with the 2018 RAM 3500 and people have been replacing parts and it does not go away. The next time I drove it, I had nothing going off. The next time I drove it, a few miles in, it started again. I took it to a RAM dealer, they had nothing on the code reader. Based on all the research I have done on line, it appears that this should be a recall item. I wanted to make you aware. We aren't what the exact fix is (without just randomly replacing parts) and we are not sure if the vehicle is safe to drive.

The ABS and traction control lights came on. The code reader reads C0020-01 Hydraulic contrl unit/ ABS Called several Ram dealers, they said this has been a problem with the Hydraulic control unit and should be a factory recall. I'm looking into having it repaired and it looks like the dealers are the only one that can clear the codeonce repaired and are the only ones who can bleed the brakes after the repair.

ABS and traction control lights flash and ding on and off. Trouble shot it at dealership and wires were repaired hoping that would take care of it…. Nope, lights and dinging are back on. I tow a large gooseneck horse trailer up and down steep hills with sharp curves, across many state lines. We have the truck full of young children ready to show their horses - hence we have the crew cab. I’ll be towing within the month. I figure it must not be a safety issue - Parts are on back order until August??? We only have 40,000 miles on the truck. I can do without cruise control, but would like a safe braking vehicle - glad my husband got a stick shift to help control speed.

Rapid intermittent ABS warning light due to a diagnosed faulty ABS module. Module has been replace previously and now experienced second failure. Ram has no replacement parts available and now I am forced to drive with inoperable anti-lock brake system and a continuous warning chime.

FOR THE LAST 10000 MILES OF THE TOTAL 53K ON THE TRUCK, THE ABS AND ELECTRONIC STABILITY CONTROL LIGHTS TURN ON INTERMITTENTLY AND THE WARNING CHIME SOUNDS. THIS SOMETIMES CONTINUES FOR 1 MILE, SOMETIMES FOR 20 MILES. SOMETIMES IT WILL NOT HAPPEN FOR 50 MILES. IT APPEARS TO HAPPEN MOSTLY ON ROUGH HIGHWAYS OR CITY ROADS. HAPPENS AT 3 MPH AND AT 75 MPH. WITH ABS AND ESC DISCONNECTED IT IS EXTREMELY HAZARDOUS TOWING MY NORMAL 16000 LB TRAILER, ESPECIALLY ON WET OR SNOWY ROADS. I HAVE NO OTHER VEHICLE. IF ABS IS REQUIRED ON US HIGHWAY VEHICLES FOR SAFETY REASONS, HOW CAN THIS NOT BE A SAFETY ISSUE? IF 2019-2022 RAM 3500 TRUCKS ARE UNDER A RECALL FOR THIS SAME ISSUE, WHY IS 2018 NOT? RAWLEY CDJR IN SIERRA VISTA AZ HAS VERIFIED THE ISSUE AND RECOMMENDED REPLACING THE HCU AND ABS MODULE, BUT IS NOT ABLE TO GET THE PARTS. THEY SAY POSSIBLY IN AUGUST. THEY HAVE OFFERED TO REFUND MY PAYMENT FOR THE PARTS THEY ORDERED AND TO DISABLE THE TRULY MADDENING CONSTANT WARNING CHIME TO SAVE MY SANITY. THEN MY TRUCK WILL NOT HAVE ABS OR ESC OR CRUISE CONTROL AT ANY TIME. IS THAT SAFE? THIS SAME ISSUE IS WELL DOCUMENTED AT NHTSA BY MANY OWNERS. IT APPEARS TO BE TIME TO START COMPLAINING TO OUR CONGRESSIONAL REPS.

The ABS system activates intermittently, causing random braking or unable to break. Took to the RAM dealership to be told the ABS hydraulic control unit 68143491AB needs to be replaced but it is on back order until August.

The contact owns a 2018 Ram 3500. The contact stated while driving at various speeds, the ABS and traction control warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS Hydraulic Control Unit (HCU) needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 23,000.

What component or system failed or malfunctioned? 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. How was your safety or the safety of others put at risk? I pull a Travel trailer loaded with our life's possessions and obviously my immediate family is with me. I cant trust or rely on my breaking system to stop my vehicle and trailer, Its a complete hazard to drive the vehicle on the road. Has the problem been reproduced or confirmed by a dealer or independent service center? I dropped my truck off today for a diagnostic to check the ABS issue and the dealer wants to charge me $199.00 + tax to verify this WELL KNOWN issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not at this time 3/20/23 Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no prior warning to the ABS failure, it simply started "dinging" and throwing the ABS failure warning on the IDC.

UNKNOWN - The ABS brake system warning light blinks on and off repeatedly. Then the warning will not occur for several days, but then starts blinking again. When this happens, the cruise control is abruptly disengaged. The code for this event is C0020-01(1/1)Active ABS Pump Motor Control-General Electrical Failure. I captured this with my own code reader as the event was occurring. When this event is occurring, the code clears itself after the warning light goes off and is not retained in the system for the dealer to see. The problem is chronic. It is the same problem that involved the NHTSA for the 2019-2022 Ram 2500/3500 trucks. I have also read that there had been a class lawsuit. I simply want Ram to repair and correct this issue

Abs hcu warning can’t stop my 20,000 lb trailer. Slid off road in drizzle. No parts Chrysler is aware of problem

The ABS light is on and it has a code But dealer cant get the HCU part to fix it this is a common problem as i have researched this in the internet. I have had part on order for 11 months now. With the abs light on the cruise control and the trailer breaks will not work. The light comes on several times a day so working this truck is not possible. So i have a truck with 70,000 miles that i cant use but have to pay for. I see nothing for a recall and what good would it be when you cant get parts?????

My vehicle (Ram 3500 w/ a 6.7 liter diesel engine) has less than 38,000 miles and the ABS Hydraulic Control Module has to be replaced. I’ve been told the part is on back order and cost to replace the unit is over $500 with another $400 plus to install this part. The dealership stated they could not place more orders until late March and since I’ve been researching and found out that this is a larger issue that has been identified to Ram with a class action lawsuit for certain years and I think that this issue should be handled at no cost to the consumer.

Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.

ABS hydraulic control unit has gone out twice in a year.

ABS failure caused cruise control to disengage at 75 mph with another car close behind that almost rear ended m vehicle. Also, ABS failure cases skidding in wet road conditions resulting to near contact with highway barrier.

I HAVE 2018 RAM 3500 THAT KEEPS SHOWING THE MESSAGE THAT I HAVE NO ABS OR TRACTION CONTROL. MY MAIN CONCERN IS STEERING AND BRAKES ARE THE TWO MOST IMPORTANT PARTS OF CONTROL AND THAT THEY ARE COMPROMISED BY FAULTY PARTS THAT YOU CANT REPLACE BECAUSE OF BACK ORDERS AND ON TOP OF THAT WHEN YOU REPLACE THEM THERE IS A CHANCE THAT THEY GO BAD AGAIN ACCORDING TO ALL THE PROBLEMS I HAVE BEEN READING ON FORUMS. THIS IS VERY DANGEROUS AND NEEDS TO BE INVESTIGATED.WE PAY ENTIRELY TO MUCH MONEY FOR A TRUCK THAT HAVE INFERIOR BRAKE PARTS!!!!!!!

Experienced a failure of the ABS Control Module and Electronic Traction Control during a light snow storm in September of 2022. Dash warning lights come on and go off intermittently. When warning lights come on and cruise control is being used, cruise control is deactivated. Dealership confirmed ABS CPU failure on 11/17/2022. Still waiting on replacement parts and are projected to be in around 4/18/2023. Warning lights continue to come on and go off intermittently. Never know how long cruise control will work before deactivated by warning lights for ABS service light and Electronic Traction Control coming back on.

NOTE: 11/18/22 filed a complaint with NHTSA - they will share it with manufacturer case number(ODI) - 11494143 QUESTION: What component or system failed or malfunctioned, and is it available for inspection upon request? ANSWER: ABS module problem Code : c0020-01 service electronic brake system Service Antilock brake system The display indicators for all of these systems come on intermittently. They effect the use of the cruise control as well. QUESTION: How was your safety or the safety of others put at risk? ANSWER: There is always the potential that any or all of these systems can fail at any moment when I am on the road driving; especially with 18k-20k pounds of load behind me. QUESTION: Has the problem been reproduced or confirmed by a dealer or independent service center? ANSWER: Yes. Galleria Tire Center in Pelham, Al. confirmed the display of all these warnings and also provide me with the code that I posted above on first question. QUESTION: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ANSWER: NO QUESTION: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

My truck is a 2018 Ram 3500 with only 12,500 miles on it, and it is not driven in the winter. Recently it has been has intermittent activation of the ABS and traction lights. It has been on consistent for over a month now. I code scan showed C0020-01 ABS module general electrical failure. I search online and talking with the dealership revealed this is a fairly common issue on 2017 and 2018 trucks and the fix with either the HCU, ABS module or both. I see NHTSA has opened and investigation into the matter so I am just reporting mine as additional truck with issues. It has not been repaired yet. Thanks.

While reviewing NHTSA's website I noticed PE22-012 concerning Loss of Brake Performance on 2017-2018 Ram 2500 and 3500 trucks. My 2018 Ram 3500 recently started giving me an ABS, traction control and/or "Service Electronic Braking System" warnings. I first noticed the ABS light shortly after I most recently rotating the tires. The tires were rotated for the 3rd time on 14 Dec 2022 with 44,158 miles on the truck. I rotate all 5 tires (spare included in the rotation). I didn't think much of it at first as I was driving in PA on snow covered dirt roads the first time the ABS light came on. After that it became more frequent with the traction control light typically also illuminating. And now more recently a message on the dash information center appears after the lights come on. The lights don't always go out after a key cycle but will often turn off in the middle of a trip. I have not taken the truck to be inspected. Nor have I noticed a degradation of braking ability. I also have never had to brake hard enough to activate the ABS on this truck, nor have I tried it just to see.

44,000 MILES, 2018 RAM 3500 DUALLY 4WD ABS Traction control unit failure and this disables traction control and cruise control. No safety braking is working and there are no solutions from RAM dealers. All they want to do is swap parts until they can find a solution and that's is if they can even get parts. If ABS is a mandatory government requirement on USA roads, why is RAM allowed to sell these trucks? There needs to be an investigation of fraud and the public being put at risk of death on our highways.

The contact owns a 2018 Ram 3500. The contact stated while her brother was driving approximately 40 MPH, the rear passenger’s side wheel started to wobble. The contact stated that the driver was able to coast to the side of the road and removed the hub cap. The contact became aware that there were only two-wheel studs holding the wheel to the wheel hub. The vehicle was towed to the dealer who diagnosed the vehicle and related the failure to NHTSA Campaign Number: 21V398000 (Wheels) however, the VIN was not included. The wheel hub and studs were replaced. The manufacturer was made aware of the failure and confirmed that the VIN was not included. The failure mileage was unknown.

Constant ABS issues, most recently HCU has been diagnosed.

The hydraulic control unit is repeatedly having problems. 09-01-2020- Inspect Brake System. Serviced at Carlock Chrysler Dodge Jeep Ram in Tupelo, MS at 19,056 miles. No parts replaced that I can recall, but the warning light and dinging stopped. The warning that was emailed to me included this information- Your vehicle's ABS Warning Light recently indicated the Antilock portion of the braking system is not functioning. If the ABS Warning Light remains on or turns on while driving, the conventional brake system will continue to operate normally unless the Brake Warning Light is on. Have your vehicle serviced at your dealership immediately. This was at 18,302 miles. 1/13/23- It sent a report with the same issue again. The mileage at this time was 45,260. The light and warning had been going on and off since at least October every time I hit a bump in the road. I tried obtaining a replacement hydraulic control unit, but it was backordered. I have another vehicle to use so I only used this one when I absolutely have to. I have read on forums that this problem is widespread and I truly believe something needs done about it. Replacing a hydraulic control unit every 30,000 miles or so at the expense of $1200 plus dollars each time is not economically feasible. The first time it was checked, the truck was under warranty. I do believe mine is extremely low miles for it's age and should not be having this issue repeatedly. 2019-2022 Have a recall, however my 2018 is having the exact s

ABS and traction control lights activate and error message states to service electronic braking system. No ABS functions as a result. Dealership diagnosed problem as the ABS HCU(hydraulic control unit). Issue can not be corrected due to unavailability of parts. This is a safety issue that should be recalled as it is a known problem by the manufacturer.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the brakes inadvertently engaged. The traction control warning light was illuminated, and the Service Electronic Braking System message was displayed. The vehicle was taken to the dealer, where it was diagnosed that the HCU needed to be replaced; however, the replacement part would be on backorder until March 2023. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 37,353.

The contact owns a 2018 Ram 3500. The contact stated that while driving at various speeds, the "Service ABS" warning message and ABS warning light were illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the ABS hydraulic unit needed to be replaced; however, the part for the repair was not available. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 25,000.

ABS Brake Module and Electronic Braking Module are issues warnings. Unknown

ABS and Traction Control lights stay on due to the HCU (Hydraulic Control Module) failure, a known problem reported from the garage. I've been waiting for a replacement part for 6 months. I was told to check back in the middle of March 2023.

While driving on a paved 4-lane road near Mount Rushmore National Memorial in dry conditions, the dash warning system began intermittently flashing "Service Electronic Braking System". The orange ABS and traction control lights also began flashing. The foregoing visual warnings were accompanied by an intermittently ringing audio warning. Retrieval of error codes from the ABS control system with a INNOVA 5610 scan tool showed: DTC CODE C-0020-01 - ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. This code relates to failure of the ABS Hydraulic Control Unit (HCU) and indicates that repair requires replacing the failed HCU with part 68143491AB (replaces part 68143491AA HCU). (SEE Fiat-Chrysler Automobiles STAR Online Publication case number S2005000004. This STAR Online publication (released on 4/28/22020) further states that if replacing the HCU does not solve the failure, the ABS control module may require replacing as well.)

ABS and Traction Warning lights illuminate, and go out, repeatedly. Dealership diagnosis indicates that the ABS Hydraulic Control Unit needs to be replaced. ABS is not functioning. Initial estimate for repair was two months, but has been updated to four months as of today (January 27, 2023).
