2018 Ram 3500 Complaint Log

Constant ABS issues, most recently HCU has been diagnosed.

Dealing with intermittent service brake system messages for over a year now. Light is constant now which means my ABS / anti skid/ and cruise control no longer function. Believe this is the ongoing HCU / ABS module known issue. Frustrating going into the winter months with such a heavy vehicle and loss of safety feature with no fix from Ram.

ABS PUMP Failed on 09/03/22. ABS light constantly coming on and off and dinging had it repaired on 10/21/22 had to wait for part, was charged 930.00 ABS FAILED 2ND TIME ABS Light constantly going on and off and dinging ON 1/31/25, Received recall C4B/NHTSA 24-896 on 01/13/25 in mail. Ferman Dodge of new port Richey refused to cover it, and their recall center refused to cover it or reimburse me. I had it replaced a second time on 4/11/25 had to wait for the part to come in. They are not honoring the recall which has been under investigation by NHTSA since 2021. So, I have been charged 2 time, another 957.00 and the second time the truck had not even been driven 30000 miles since last repair. So, every 30 to 40 thousand miles the abs pump fails possibly causing the brakes to malfunction. They are also saying that it was repaired on 12/05/25, Truck was not in for service on that date, see attachments,

September-October 2022 --The Anti-Braking System module has quit working. (ABS). Requested replacement part from Dealership in October 2022. Dealership advises Mopar cancelled parts request to them. I have no anti braking working on vehicle. Dealership advises me to contact Mopar directly for help. I advised them that wasn't my job it was theirs' .

ABS light is on and while driving a message appears on dash which indicates "service electronic brake system." It comes on and stays a few seconds and goes off and then comes back on. Mechanic has diagnosed and found code C0020-01 which indicates ABS pump motor control general electrical failure. This truck only has 16,000 miles on it.

Intermittent warnings to service ABS system and electronic Braking System. I have had this checked by an independent mechanic and all sensors checked good. He was told by the local dealer that the ABS module is on backorder with no estimate of availability. Truck is almost due for annual inspection and registration and I do not know of it will pass the inspection.

I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit.

ABS and Traction Control lights and DIC alarms came on while driving. They stayed on for a few minutes then went off. Also the service trailer brake system message came on. This has happened several times now turning off cruise control too. I reseated all fuses and went for two weeks before it started happening again. Happens sometimes as we go over expansion joints or hit potholes while driving at highway speeds. I notice several other reports of this here at NHTSA site and various RAM forums across various RAM years.

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.

Intermittent flashing and dinging for ABS system. Message in dash says “Service Antilock Brake System”. Has been diagnosed and confirmed by credited service shop. The problem occurred around 80 thousand miles, a year or so ago.

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.

ABS and EBS sytem is shutting on and off on highway at speeds. This is a random event that started at about 20,000 miles then went away for about 6,000 miles then came back at 29,000 miles whil on a 1,500 trip and is now not going away. The system shuts on and off constantly with chimes and alarms to "service ABS/EBS. I have the truck at the dealership and they advsied it needs to have the ABS pump and control module replaced. I have looked on the internet and see several hundred complaints for the same issue. The delaer says this is not a recall and is not covered by warrenty. To me this seems like a safety issue that is being ignroed by Chrysler corp / Ram. They are looking at the numbers and not enough people have been in accidents to justuify the cost of a recall. I have a video of the issue system turning on and off constntly at about 62 MPH as I enetered the freeway from and on ramp to merge in trafic.

Abs and traction control system stopped working with only 33000 miles. Dealer states module and pump need replacement. No warranty as vehicle is 4 years old as no driving during covid. This has happen to 1000's of ram trucks. Repair is $1600. Will have to drive with out repair.

A 2018 3500 RAM WITH 31K MILES JUST EXPERIENCED TWO WARNINGS ON THE DASH. 1. SERVICE ELECTRONIC BRAKE SYSTEM 2. SERVICE ANTI-LOCK BRAKE SYSTEM DIAGNOSED USING OBD BY MIDAS: BOTH ABS MODULE AND PUMP ARE GOING OUT. VEHICLE IS NOT CONSIDERED SAFE TO DRIVE. AREA IS BACKLOGGED FOR THESE PARTS (1000). THIS IS A MAJOR SAFETY ISSUE AS I'M TOLD THIS IS A CRONIC PROBLEM. COST TO REPAIR IS EXCEEDING $1800 NOT INCLUDING THE DIAGNOSIS. CALLED OUR LOCAL DODGE/RAM DEALER AND THEY SAID IT IS NOT ON ANY RECALL. WHY NOT? ITS MY UNDERSTANDING THAT NHTSA INITIATES SAFETY RECALLS WHEN VEHICLES ARE IN PERIL OF CRASHING DUE TO A FAILURE. WE MADE IT HOME BUT IF IT WENT COMPLETELY OUT, WE WOULD NOT BE HAVING THIS DISCUSSION.

In August 22 I replace the hydraulic control unit on this truck to fix the intermittent abs and traction control message and ding on my evic and now in October 23 I am getting the same intermittent messages again. I paid and did the repair back in august myself but now seems to be a delay in getting the parts. I bought the truck in December 2017 so if you average the miles the second HCU only has approximately 8000 miles on it. These parts should last longer than that. The truck has only 47000 total miles on it.

My car keeps giving the warning that the ABS brakes need to be serviced.

1. Serv anti-lock brake system,. 2. service electronic braking system. ABS light on and traction control light on. Diagnosed issue is Hydraulic control unit and possible module antilock brake system. Dealership does not have the parts for repair. Manufacturer refuses to put a recall notice even though several complaints have been issued by the RAM community.

The contact owns a 2018 Ram 3500. The contact stated that while operating the vehicle, the ABS and traction control warning messages were displayed, and the cruise control feature became inoperable. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet notified of the failure. The failure mileage was 6,000.

Our 2018 RAM 3500 is factory equipped with Nexen LT235/80R tires. This Ram has 16023 miles on it. We pull a 36 foot 5th wheel RV, weighing approx 15K lbs. When coming home from a trip on July 16th 2022 at 7pm, on I75 south around Sidney Ohio, 15 miles from home. This is a 70 mph zone, when we got to 60 mph the entire cab and bed started shaking and vibrating to where it was hard to keep on the road. At this time we feared of being or causing an accident. We exited and visually inspected the Ram and unit, and visually looked to be fine, We continued home via back county roads at a 35mph speed as the fear was still within us from what we just experienced. On Monday July 18th 2022 I took the Ram to Tires Choice 1101 West Main Street Troy Ohio [XXX]. The tech and I took the Ram out and reproduced exactly what we experienced on July 16th, without the trailer hooked. After inspection while on the lift it was found that the belt was broken on the front passenger tire , and was told we were lucky this did blow hauling a 15k trailer. I replaced all 6 tires in fear that the other tires may also be faulty, and if fear of having or causing an accident to would result in serious injury or even death. After researching this particular Nexen tire I found SEVERAL negative and shocking reviews. THIS TIRE NEEDS TO BE REMOVED AND RECALLED FROM THE PUBLIC. Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Abs hydraulic unit and module needs replaced

Right before 36000 miles the ABs and Traction control lights come on and off intermittently. I took the truck to my local dealer and was told 2 components needed to be replaced. They informed me it was not covered under warranty and they did not have the parts nor knew when they might get them in. This has been 4 or more months now and the lights stay on more often than they are off. I can’t use cruise control and it will not pass inspection with the lights on.

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.

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.

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.

Abs/hcu faulty, brake warning light, message, and alarm will sound on and off while driving. I have tried to buy the parts and they are not available through dodge with no estimated availability. This has been going on for a year.

The ABS sensor warning indicator comes on randomly. Normally every 45 seconds or so. The cruise control will not work when the warning triggers. The dealer replaced the sensor and the HCU units when the truck had @ 40k miles. Problem reoccurred within 6 months. The replacement parts have not been available now for 18 months and the dealer tells me they have no expectation when the parts will be available.

ABS System flashes on and off that it needs to be serviced, also cruis control doesn’t work. Took it to dealer to get it diagnosed. Dealer says the HCU needs to be replaced and the ABS pump needs to be replaced and also that cause the brakes and rotors to wear out and they need to be replaced too.

The contact owns a 2018 Ram 3500. The contact stated that while driving 75 MPH, the ABS warning light, and the service tow brakes message were displayed. The contact exited the freeway, and while depressing the brake pedal, the brake pedal was firm, and the contact stood on the brake pedal. The ABS warning light was illuminated. The contact was hauling a trailer during the failure. The contact pulled into the entrance to the dealer and pulled over and turned off the vehicle. The contact walked up to the dealer and explained what had occurred. The vehicle was diagnosed with ABS module failure. The vehicle was repaired; however, a year later, the ABS module failed again. The vehicle was repaired; however, the failure persisted. The brake light and ABS warning lights were intermittently illuminated. The vehicle was parked at the residence undriven due to the safety concerns. The manufacturer was not notified of the failure. The failure mileage was approximately 33,000.

Truck has 22000 miles ABS and traction control lights constantly coming on and off along with service electronic braking system warning. Kicks the cruise control off every time it pops up. The cause is the abs module which apparently is a very common issue on these trucks and costs over $1000 to repair

Unsafe and very hesitant acceleration nearly causing accidents. Long lag time between pressing the accelerator and engine responding to throttle input.

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 contact owns a 2018 Ram 3500. The contact stated that while driving at various speeds the ABS, traction control, and Hydraulic control unit (HCU) warning lights remained illuminated, and the cruise control became inoperable. The vehicle was taken to the local dealer who determined that the ABS and HCU control modules were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 587,000.

ABS FAILURE / DEALER SAYS WAITING ON PARTS/ WAITING FOR OVER ONE YEAR

Warning of Anti skid system needs service

"Service Electronic Braking System" intermittently flashes in the dashboard, along with the orange ABS and traction control lights. Seems to happen more on bumpy roads, goes away on smoother roads, then randomly comes back. Over the span of a few weeks, the frequency of the error message has increased, and now the error lights stay on almost all the time. 47,500 miles and purchased new 3 years ago. Here is a video of what happens: https://photos.app.goo.gl/hZ3GAAq3UryvgJWV9

ABS and Traction control pump system electrical failure. Went to a Dodge Dealer and had the system read due to light coming on and off. Originally started around 38,000 miles on the truck. A code came up C0020-01. ABS pump motor control electrical failure. Researched on the net. Seems to be a big issue from 2013 on up on trucks. Chaffing wires? Pump failure? Dealer said the ABS Pump could Possibly be bad. Wondering if there is a safety Recall or will have one. I have my truck scheduled for repair next week. Estimated cost of $700.00 according to service department.

The brake Brake HCU pump failed at 33,489 miles and was replaced under warranty last year. Now with 45,000 miles I have the same problems occurring and will have to go to the dealer again. The traction control, ABS and cruise control all do not work and the service electronic brakes message flashes on and off. The problem is intermittent. I've read online that the replacement parts are unavailable from the dealer or on a 6-8 month lead time. It seems this is a fairly common failure in the 2018 3500 trucks and Ram needs to find a better fix than a part that lasts 12,000 miles after the original only lasted 33,000 miles.

The contact owns a 2018 Ram 3500. The contact stated while driving approximately 35 MPH, the contact observed that the check engine warning light was illuminated and the coolant temperature warning light was also illuminated. The contact pulled over safely and turned off the vehicle. The contact drove the vehicle to a dealer where it was diagnosed and determined that the thermostat, coolant sensor, and air intake heater relay needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V798000 (Electrical System) however, neither the VIN nor the vehicle year was included. The manufacturer had been informed of the failure. The failure mileage was approximately 67,000.

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?????

The Automatic Braking System (ABS) and Traction Control lights come on intermittently. They flash and and sound at random. A RAM dealer stated the lights must be on for them to get a proper code to determine the problem. This is an extreme safety problem that could occur at anytime ABS and traction control may be needed.

The contact owns a 2018 Ram 3500. The contact stated that the ABS hydraulic control unit was making an abnormal beeping noise. While driving at various speeds with the cruise control engaged, the system disengaged without warning. The vehicle was taken to the local dealer, and the contact was informed that the ABS system needed to be replaced. The vehicle was repaired, but the failure recurred. The contact called the local dealer and was informed that parts were on backorder. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 78,000.

Uconnect screen delamination causes phantom button pushing while driving down the road. This causes random buttons to be selected and for things to start happening while driving. Driving distracted is dangerous driving. It will randomly call people, including using the SOS functionality. Making non-emergency calls to the emergency line is unacceptable. Once while driving, it turned the radio on and my volume was cranked up. I almost crashed into the car next to me because it scared me half to death. This is a known issue from what I've been reading on RAM forums and almost always shows up outside of warranty. The manufacturer should be held accountable for this to prevent future wrecks, distracted driving, and unnecessary SOS phone calls.

The warning chirp occurred and the ABS and ESC lights came on the first two times. The incident happened so quickly I could not clearly determine which warning lights illuminated. On April 18 with just over 39,000 miles on the vehicle the chirping alarm and the ABS and ESC light illuminated. In addition two warnings appeared in the dash: "Service Antilock Brake System" and "Service Electronic Braking System." The warnings happened multiple times per minute in some cases. Other times the vehicle would go for many miles without the warning. Every time the warning chirp was heard the cruise control would disengage. I did not notice any problems with the brakes of the truck. In researching the issue I learned that many people are having this problem. I contacted Ram and they directed me to a dealer who diagnosed the C0020-01 fault code and that the hydraulic control unit (HCU) for the ABS system was defective. According the the TSB Ram has put out about the issue the ABS module could also be bad, but the first part of the repair it to replace the HCU and if the problem persists to then replace the ABS module. Ram apparently has an inconsistent level of support for owners experiencing this malfunction with some getting the repair done out of warranty, while others have to pay for the repair. Because it is brake related it seems this should be an item replaced as a safety issue, no matter what the mileage on the vehicle.

HCU / ABS system failed at 34,000 miles resulting in the ABS system and speed control system not working as designed. It was a costly repair not covered under warranty however it needed to be repaired as not having the braking system working as designed was unsafe. This is a known issue with the 2017 and 2018 RAM heavy duty trucks. This unit was recalled on newer models however the the 2017 and 2018 models were not recalled resulting in an expensive required repair.

The contact owns a 2018 Ram 3500. The contact received notification of NHTSA Campaign Number: 21V398000 (Wheels) however, the part to do the recall repair was unavailable. The dealer had been notified about the issue; however, the contact was informed that parts were not yet available. The manufacturer had been notified of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. Parts distribution disconnect.

Ram has issued a service bulletin to replace the ABS control module on 2018 Ram 2500 and 3500. This needs to be a recall as Ram is forcing customers to pay out of pocket or drive a vehicle without functioning ABS.

Abs electronic brake light issue,brakes spongy and feels like it’s lost braking power.

The contact owns a 2018 Ram 3500. The contact stated that after taking the vehicle for a radiator repair at Phillips Chrysler Jeep Dodge Ram (3440 S Pine Ave, Ocala, FL 34471) he was made aware of NHTSA Campaign Number: 21V398000 (Wheels) however, the contact stated that he was not informed that the vehicle was repaired. The contact stated that while driving at an undisclosed speed the contact heard an abnormal sound. The contact pulled over to inspect the vehicle for a flat tire however, the contact saw no failures with the tires. There was no warning light illuminated. The contact exited the vehicle and noticed that some of the wheel studs were broken. The vehicle was towed to Advantage Chrysler Dodge Jeep Ram (8311 US-441 suite b, Mt Dora, FL 32757) where it was diagnosed that the rear passenger’s side wheel hubs and studs needed to be replaced. The vehicle remained at the dealer awaiting the parts for the repair. The manufacturer was made aware of the failure. The approximate failure mileage was 102,240.

Service electronic brake system with the traction control light lit. Seems to be a common occurrence
