2018 Ram 2500 complaints

Service electronic braking system continues to flash along with Service Antilock brake system--This is a failure of the HCU (hydrolic control unit) that should be a RECALL. Thousands of people are having the same issue.

The contact owns a 2018 Ram 2500. The contact stated while driving at various speeds, the ABS and traction control warning lights illuminated. Additionally, a message advising to service the vehicle was displayed. The dealer was notified of the failure and informed the contact that it was a known failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000. The VIN was not available.

My ABS light came on and then shortly later I noticed that my stability control system was disabled and its warning light came on. I also lost the ability to use my cruise control. Took vehicle to the dealer and they determined that the ABS Control unit needed to be replaced. They trouble shot the issue and replaced the ABS Hydraulic Control unit. This repair is for the same recall as 85B for Ram 1500's.

Nothing has happened so far, however it has come to my attention that the grid heater bolt will eventually deteriorate until dropping into the intake and then into the number six cylinder. This could be a serious safety issue for me when pulling our 2970 RL Imagine Travel Trailer that could possibly weigh upwards toward 10,000 pounds fully loaded. We have traveled and likely will again Interstate 75/85 through Atlanta, parts of which has as many as six lanes. In addition to a potentially serious safety issue there would be a considerable repair cost with likely having to spend up to $20,000.00 for a new engine destroyed by a defective bolt in an extremely terrible location, and my truck has only between 50,000 and 60,000 miles on it with this engine being known as a million mile engine.

Continually getting ABS warning and "Service electronic brake system soon" warning. Electronic Stability Control suddenly shuts off without warning to include cruise control if engaged. ABS and ESC lights remain on most of the time with constant chiming. This is a widely known problem. Recall just came out for later model years but not these.

The contact owns a 2018 Ram 2500. The contact stated while driving 60 MPH, the ABS and Service Electronic Stability warning lights illuminated. The contact had previously taken the vehicle to the dealer for the same warning lights being illuminated. The contact had taken the vehicle to a dealer for the first failure. The dealer diagnosed the vehicle and determined that the ABS module had failed and needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact had not taken the vehicle back to the dealer for the most recent failure. The vehicle was not repaired. The contact had researched online and related the failure to NHTSA Campaign Number: 24V653000 (Service Brakes, Hydraulic, Electronic Stability Control (ESC); however, neither the year nor the model was included in the recall. The manufacturer was informed of the failure. The failure mileage was 54,590.

1. ABS SYTEM FAULTS, NO KNOWN TRIGGERING, CONTINUOUS FLASHING, RESETTING, AND GOING OFF AGAIN. DROPS THE TRUCK OUT OF CRUISE CONTROL. 2. I WOULD SAY YES, MY SAFETY AND THE SAFETY OF OTHERS ARE PUT AT RISK WHEN THIS HAPPENS, ESPECIALLY WHEN THE TRUCK DROPS OUT OF CRUISE CONTROL AT RANDOM UPON ONSET OF THE ISSUE. 3. ONSET 17SEP24, CONTINUIED 18SEP24, TWO DAYS IN A ROW NOW. TROUBLESHOOTING CALL HAS BEEN MADE TO DEALER THIS AM FOR FOLLOW ON DIAGNOSTICS. CURSIARY RESEARCH DONE THIS AM SHOWS MULTIPLE REPORTS OF FAULTY ABS SYSTEM PARTS AND MODULAR ISSUES BEING REPORTED, CLASS ACTION LAWSUITS, NHTSA REPORTS ETC. 4. NO 5. YES, ABS SYSTEM FAILURE WARNINGS, ABS FAULT LIGHT WITH SYSTEM CHIMES

I am getting a code "C0020-01" causing my vehicle to not brake properly, traction control is deactivated, constant chime of the warning system, loss of cruise control and unstable driving conditions when driving on wet roads. Researching the code has led me to forums on the internet which shows there are several incidents of this issue common to the 2017-2018 Ram 2500 vehicles.

ABS brakes module. Failed at 60k miles and has been on back order for almost 2 years. So I have not had ABS brakes in almost 2 years now. Seems to be a major problem. I know of 5 people with the same issue.

The ABS warning light and alarm come on while driving. Loss of ABS and cruise control, near rear end collision by following vehicles on the freeway while using cruise control. Ram knows they have a problem with 2017 and 2018 2500 pickups. Why no recall? Safety problem!

The system that is malfunctioning is the braking system, ABS module, or HCU. The traction control light and ABS light intermittently flash, disengage cruise control and the antilock braking system. The lights never stay on consistently but rather they come on and off without any pattern. This same issue happened a right at 2 years and 30k miles previously which the truck was then taken to a dealership and supposedly replaced. However, the same issues are happening again with no indication as to why this part keeps failing. Truck has less than 90k on it currently, mainly highway use. There have been no inspections done, however, I plan to take it to the dealer in the near future.

Abs light and traction control warning light constantly coming on and off while driving and a warning sound playing every time the lights come on in the dash, which is very annoying and frustrating. The truck is under 30 000 miles and unfortunately is out of warranty. I don’t drive this truck very much and having this kind of problems with it is totally unacceptable.

The ABS HCU has failed again this is the third time. The brakes feel spongy and the cruise control and 4wd does not work. The cause is unknown faulty design of parts. I don’t remember the mileage of the first or second failure.

“Service AntiLock Brake System” and “Service Electronic Braking System” lights flash intermittently while driving. ABS, Traction Control., and Engine lights up on dash. Code is C0020. It has done this several times while driving. Vehicle has just over 34,000 miles on odometer. Its a common issue apparently known by Stellantis and they had changed supplier and part number.

Abs light and braking system needs servicing and found out it is a common problem with Dodge Rams , scanner shows ABS pump motor control general electrical failure

Vehicle will display Service Electronic braking system randomly throughout driving the vehicle. The cruise control is not available when the code shows up. Also, the ABS and Traction Control lights pop up. The problem will shortly go away when I press the brakes all the way.

ABS been down since July,2023,alarm dings constantly, dealer says no parts available, and Chrysler is no help

ABS service light was intermittently coming on and off for a period of time and now is constantly on. This results in constant beeping and also prevents the cruise control from working.

The contact owns a 2018 Ram 2500. The contact stated that while driving 70 MPH uphill and hauling a loaded trailer, the contact noticed that the radiator fan had engaged, and the vehicle made an abnormally loud shredding sound and the engine started overheating. Additionally, there was smoke coming out of the exhaust pipe and there was an abnormal coolant odor. The contact pulled over to the side of the road and inspected the vehicle. The contact noticed that the rubber part of the radiator fan shroud was stuck inside the radiator fan and was shredded, causing a hole in the rear of the radiator. The contact noticed that there was no coolant inside the reservoir. The vehicle was towed to the dealer, where the radiator, the fan, and the fan shroud were replaced; however, the failure recurred while hauling a loaded trailer. The vehicle was towed to a second dealer, Cronic Chrysler Dodge Jeep Ram (2515 N Expy, Griffin, GA 30223), where the same repair was made. Additionally, the dealer installed pins on the radiator fan shroud. The contact stated that the pins were detaching, and the contact was concerned that the failure would reoccur. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

Vehicle has a control module failure causing the ABS, Traction Control, Cruise Control and other braking systems to intermittently turn off and on. The vehicle has been brought in for this issue and we have been told they are unable to get parts to replace the module at this time. This has been an ongoing issue for multiple years, with the failure occurring at a higher percentage of time the vehicle is driven now.

ABS needs service. Was quoted 2k from Dodge for repairs. As well as electric brake system not working Chrysler told me it is safe to tow my 10000 lbs rv with the errors and no ABS.

I received the recall notice V06, for the Drag Link, I purchase 4 new tires and took the truck in to have the repairs done, the dealership informed me that I also needed upper and lower ball joints both sides and front end alignment, I had them preform all that they said it needed. I took the truck back because I noticed excessive tire were and they told me that the Drag link needs replaced, the alignment redone and that I would have to pay for it

I bought my 2018 Ram Truck in 2019 new from a dealership. the first sign of a problem started at about 25,000 mi. It started sending tones with the message "Service Electronic Braking System" and "Service Antilock Brake System". It would toggle between these two messages and sound warning tones while the truck is in operation. The first shop I took it to replaced my carburetor. That was not it. I then took to a Diagnostic Shop and the message from the computer read: ABS pump motor control general electrical failure. On the dash it also shows the icon for slippery road conditions. Looking on the internet i realized that this is affecting 2017's and 2018's. There are a lot, maybe all of them being affected by this potentially dangerous malfunction.

Constant on and off of abs and traction control due to abs module and hydraulic control unit failure. It’s a known issue by fca.

Driving on cruise control the Anti-Lock brake light came on causing the cruise control to turn off at highway speeds. The anti-lock brake system, cruise control and traction control all quit working. Warning light went out and then all started working again. Very intermittent problem at first then started getting more frequent. After research I found it is a known problem on 2017 and 2018 ram pickups. The parts to fix it are revisions from the original and known bad but no service bulletins or recalls. There has been a recall for 2019 and later but Ram is not addressing the earlier problems.

CONSTANT PROBLEM OF SERVICE ELECTRONIC BRAKING SYSTEM AND TRACTION CONTROL LIGHT GOING ON AND OFF. HAS BEEN HAPPENING FOR THE LAST 6 MONTHS ON A TRUCK WITH ONLY 25,000 MILES ON IT.

When driving and hit a bump the abs/ traction control lights come on and off. Does this consistently with bumps. Problem is not a wheel hub or sensor, when scanned it comes back as a C0020-01 code abs pump motor control general electrical failure. Safe to assume that the brushes within pump motor are sticking and failing to slide properly.

The anti-lock brake control unit failed while under warranty and was repaired and it has failed again with only 53737 mi. When the ABS light comes on the traction control light comes on and the cruise control quits working. Seems very unsafe. Don't know if I can afford to fix it and no parts are available.

Truck chimes and says service ABS brake system and service electronic brake system. Traction control and ABS light pop on and off intermittently while driving.

Brake module malfunction kicks out cruise control and dings constantly. Seems to be a recall for other years but this year is missing?

ABS and traction control modules randomly deactivate leaving 20,000 LBS of truck and trailer without the ABS and traction control system to aid in emergency stopping. This is A KNOWN ISSUE to Ram who refuses to acknowledge and properly recall and provide replacement parts on some of the most heavily used tow vehicles.

At 41,000 miles “check abs and electronic brake system” warning started coming on causing system failure to vehicle. Vehicle was taken to dealer with it requiring replacement of Hydraulic Control Unit and ABS control unit. Now at 71,000 miles same problem is occurring with cruise control deactivating, traction control failure, and ABS failure without warning. Apparently this is a known issue by RAM that continues to cause system failures across the vehicles sold between 2017 and 2019. To date I’ve not had an accident due to this issue but it is definitely a safety issue that RAM should be forced to issue a recall to correct! Please respond with updates. Thank you…

Abs light comes on and off all the time. Randomly and hitting a bump. Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. It doesnt seem to matter what speed you are going. Upon research online looks to be a common problem that RAM has. There is an issue with pump motor electrical brushes making contact which causes this issue.

ABS control module fault code. Seems to be a lot of people having issues with this on 2017 and 2018 year model trucks. A class action would be nice or some sore of solution for ram to make a permanent fix.

Second time my antilock brakes module has gone bad with 56000 miles not covered under warranty. Cost me $1700 to fix a little over two years ago. It went out again today and they said they wouldn't cover it. I have been reading about this and it's a major problem with many Ram trucks. I feel it should be taken care of on a recall and not having to pay every time it goes out. Ram knows this is a big problem and not doing anything but taking my money. Thank you

Two issues with my truck. #1. The ABS HCU was replaced under warranty once. I am now at 75k miles and it is doing the same thing again. Difference is I'm having to pay for it. #2. The Clock Springs has been replaced once already and now needs it again. I paid the first time and am now having to pay again!!! Absolutely not acceptable!!!

This truck has had two major REAR-END repairs. After the last one it vibrates. Several sets of tires and even a new set of rims and it still vibrates. NONE of the dealers can locate anything.I took it to a shop that has vibration detection equipment. Their results show the issue is in the rear end. I get no resolution or help in resolving the issue. I have been out a lot of money on this truck due to odd break downs and issues that Ram refuses to acknowledge. I am beyond sick of this. I paid a lot of money for this junk.

Driving in traffic a vehicle in front made a sudden emergency manuver. I braked to avoid, the ABS warning light flashed and beeped "service abs system". The failed abs system nearly caused an accident. Took to the dealer, and they replaced the failed abs module under warranty at 20k miles on truck. Now, with 34k miles it failed again. Parts are reported to be on national backorder. Friends with this model truck are experiencing similar failures. Fact that these trucks are often work trucks, towing etc make these failures very serious. I urge you folks to push Ram to recall these defective parts before someone is killed.

Abs light comes on and off all the time. Randomly and hitting a bump. Code is c0020-01. The cruise control is disabled when this occurs. Also I assume abs would be disabled also. Took truck to dealer to look at. They tell me there is no engineering fix at this time for this issue and no parts available. Upon research online looks to be a common problem that RAM has. There is an issue with pump motor electrical brushes making contact which causes this issue. Truck is a fairly low mile truck.

Vehicle warning lights and message on dash keep going off and on indicating need to service the ABS system following a break-job. Warning comes and goes as many as 30 times per minute. Anti-lock brakes and traction control are currently inoperable. Dealer cannot diagnose between electronic ABS module and hydraulic control unit blames one or both as culprit. Module is on back-order from Mopar due to this being a widespread and prevailing issue and they even suggested the matter has been escalated to their engineers for a more robust solution. My ABS pump module was replaced under warranty at 90k miles. I was quoted $1800 to repair upon part availability. I would appreciate the NHTSA investigating this matter for eligibility of a forced recall with Ram to pay some or all costs to remedy.

My abs/traction control and electric braking system warning light has recently cone one for the third time. The first time it was repaired around 3,200 miles, the second time was around 32,000 miles and now around 72,000 miles. The light flases randomly and when it does i can't use my cruise control.My vehicle can be inspected any time.

Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. Both the ABS and traction control lights are illuminated. I contacted my local dealer and they indicated that this isn't an immediate safety concern and is due to an electrical issue for which they haven't solved. They quoted me $1,600 for the replacement of the Anti-Lock Brake System Module and Hydraulic Control Unit. After some online research, it seems that this is a common issue with many resulting in total brake failures. A potential brake system failure should be a recall for obvious reasons.

The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the air bag warning light remained illuminated, and the message "Service Air Bag" was displayed. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer, but the cause of the failure was not yet determined. The manufacturer was not contacted. The failure mileage was approximately 127,000.

ABS control module/pump very common problem with this year truck that Fiat/Stellantis needs to address.

SERVICE ABS BRAKE SYSTEM WARNING LIGHTS.THE ABS UNIT WAS REPLACED 6-7-2022 AT FELDMAN DODGE WHEN THE LIGHTS CAME ON AT 15525 MILES.NOW THE LIGHTS ARE COMING ON AGAIN AT 30000 MILES THIS SEEMS TO BE A KNOWN RAM PROBLEM.PLEASE ADVISE [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Service Electronic Braking System and Service Antilock Braking System lights have been popping on the dash for the last two months nonstop at random times. Sometimes I can drive for hours and not see them, then other times they flicker on and off constantly. It’s very frustrating as my truck has only 27000 miles for a 2018. I’ve checked rear wheel sensors and found a tiny bit of metal shavings which from what I’ve read could be wheel bearings but still don’t know a for sure answer. I’m about tired of chasing down this rabbit trail. What caused this was I was backing my trailer and I started to spin a little and the lights came on so I clicked into 4x4 and lights stayed on. I turned the truck off and thought nothing of it and next morning truck had no lights on that day. But ever since then I’ve been plagued with them going on and off.

The abs/traction control lights are coming back on again. The abs control module and the hydraulic control unit were replaced when the truck had 34,000 miles. Now it has close to 60,000 and it has started doing the same thing again. Talked to the dealer and they said it would be close to $2000 to do the repair this time since it isn't under warranty. I have seen many of this same problem in a lot of the ram or cummins forums and feel this is a known issue and should be recalled. You lose the abs and traction control when these are out but it is intermittent. Fortunately, I haven't had an accident from this so far but could very well see how it could cause an accident. When my traction control was out the truck fish tailed on a wet road.

ABS pump motor control and anti-lock brake hydraulic unit is out again. first time replaced at dealer on 12/27/2019 second time8/10/2022 and now ABS light flashing again for about 3 weeks now with code c0020-01. This should be a recall it is very dangerous to be hauling heavy equipment with this reoccurring problem approximately every 20,000 miles or so.

The issue with the Electronic Braking System and ABS has worsened. The two warning lamps are almost constantly on, or rapidly come on and go off rapidly. If I'm towing a trailer, all braking is lost momentarily - brake pedal to the floor - including the trailer brakes. The trailer brakes do not return until an ignition cycle, if the warning lamps stay off, that is. The dealer says no parts are available, but won't even take it in for troubleshooting or attempted repair. This truck scares me. This has been an issue for about two years and 20,000 miles.

ABS/HCU problem. Code C0020-01
