2018 Ram 2500 complaints

I am receiving an alert in my truck that states, "Service Antilock Brake System." The emergency warning sound and lights on the dash/display appear constantly. This also affects the "Speed Control" as it kicks off the cruise control when the emergency warning sound and lights come on the dash. I have taken the vehicle to a RAM Dealership who diagnosed the issue, but was advised that parts are on backorder, which is unacceptable as this can be a very dangerous and potentially costly situation. I believe that NHTSA should look into this and provide a recall on the vehicle and expedite the process to getting, not only my vehicle, but others around the country fixed in a timely manner.

ABS Pump Motor Control - General Electrical Failure, code C0020-01, needs to be replaced. A critical item. Part is not available. I live full time in my 5th Wheel 40’ RV. Part may be under some engineering review due to failures. I need new part asap. No dealer has them. Truck is grounded.

Antilock braking system and electronic brake system warning lights flash on and off frequently while driving.

ABS Module failure and Hydraulic Pump failure.

ABS, and traction control systems fail intermittently. Lights come on and flash and ABS and cruise control no longer work. Happens at various speeds and times. Sometimes can be addressed by pulling over turning off the vehicle and restarting. Dealer states that ABS module and pump need to be replaced but have no available parts. I was advised that the estimated cost is ~ $1800 and the problem may arise again. This is on a vehicle that has less than35k miles

My truck has 32000 miles on it. Its just out of warranty and the ABS Hydraulic Control Unit is out again. This will be the third HCU put into my truck. This is a known problem from Ram and it has never been addressed. NHTSA please have RAM make it right and fix the problem so costumers are not spending 1500.00 every 15,000 miles.

The ABS/Traction Control System (TCS) error flashes intermittently while driving the vehicle. This dash warning states the ABS and TCS systems are non-functional. The vehicle is available for inspection. Safety is adversely impacted by the braking system not performing its design function. Traction Control perturbations can also have adverse impacts to the drivers control of the vehicle. This vehicle has has yet to be inspected, but similar failures for this make/model indicate a faulty ABS module and/or sensor issue. Warning error messages are broadcast frequently via the instrument cluster display. Initial warnings @ 32k miles, fall of 2023.

Service electronic brake system keeps coming up on the dash. When this happens you lose cruise control, ABS, and your abs and traction light come on. This goes on and off constantly and dings every time it happens. This is a huge problem that Chrysler is aware of but will not do anything about. I had mine replaced once and 23 months later I have the same 13000 dollar issue.

ABS goes on and off continuously. Warning messages and beeps constantly. Started October of 2022. Independent service center has been trying to get a replacement nodule from the manufacture for all most a year.

The ABS/Traction Control light continually goes on and off. I took the vehicle into Tate Dodge Ram Service center in Glen Burnie, MD the first week of January 2023. They diagnosed the problem as the ABS Control Module and Hydraulic Control Units as bad. I was told that it would take 2 weeks to get the parts. I checked back with them 2 weeks later and the ETA had changed to March 16, 2023. I left the vehicle with them and checked back after March 16th, the ETA had then been changed to August 15, 2023. I picked the vehicle up from the service department and check on it August 15th. They had received on of the part, but the other one was scheduled to be delivered Sept 15, 2023. I contacted them again on Sept 18th, when I was told that the part would not be delivered until February 15, 2024 (13+ months). The lights continue to go on and off with a bell each time the light comes on, which is very distracting. It is unsettling to drive, not knowing if my brakes will work in an emergency or if the traction control will work when we get slippery road this winter.

Service ABS and Traction control warning lights on. Computer says ABS circulation pump is bad. Part is unavailable. There should be a recall, this is a known and documented safety issue. Part is discontinued, how is it possible to disregard this issue? What are we supposed to do........drive a vehicle that wont stop as it should?

The hydraulic control unit (HCU) of the anti-lock braking system (ABS) is defective (part number 68143491AA). Without warning the defective HCU will cause the ABS and or cruise control to shut off. If this happens during hard braking, on slippery terrain or in heavy traffic, it could cause an accident. The indications the system is having a problem are warning messages on the dash display, which is great, but the warnings goes on and off for no apparent reason (does not stay on). This can happen at any speed. I replaced my HCU with the same part number (68143491AA) approximately one year ago. This corrected the problem until a couple of weeks ago when the same indicators started again. After a lot of research (Google, Ram heavy duty and Power Wagon forums) I came across one post that discussed how a brush in the motor for the HCU can become stuck, failing to maintain electrical contact with the motor windings. With nothing to lose, I decided to pull the motor off my HCU and take it apart. Once apart, I did determine that one of the brushes was in fact stuck. I am not sure if the brush became stuck just because of dirt or if the metal body the brush slides in was crimped too tight (could be a combination of both). I was able to free up the brush and put the motor back together; the motor functioned properly when bench tested. Unfortunately, I have not been able to reinsert the motor back into the HCU body (plungers are in the way and need to be compressed). I do not know if th

About a month ago the ABS and Traction Control warning dash lights started coming on intermittently with warning tone. They go on/off randomly or not at all some days. I had the codes pulled and there was only one, C0020-1 General ABS System Failure. This has not resulted in any dangerous vehicle incidents as of yet, but I must have my vehicle to tow/work and the expensive replacement parts are on indefinite back order. I understand this is a very common problem for 2017-2018 Ram HD trucks and Ram is doing very little to prioritize a solution.

I have a 2018 Ram 2500 - 6.7 Cummins diesel, The service ABS system and service electronic brake system dash lights come on and go off constantly. Every time they come on there is an alarm that goes off, and it also kicks the cruise control out. This problem started had around 32,000 miles and has continued to now 71,000 miles. I have tried multiple times to have this, diagnosed with a system reader with no luck. Have had the system reset also with no luck. I’ve read on multiple Dodge/Ram forums that this is an ongoing problem with 2017-18 and up Rams that they refuse to address. Any information would greatly be appreciated to get these problems resolved as it appears there are multitudes of people having the same issue. Thank You Note: The mileage on the pictures below is not when the problem started, these were a picture of the lights that I could catch in between them coming on and going off so I could show the mechanic what was happening.

I started getting a "service electronic braking system" message in the EVIC intermittently

The ABS module is bad. Can not drive the vehicle for fear the brakes will fail, especially when pulling a trailer loaded with animals (farm). This is ridiculous, a $86K vehicle with less than 40K miles (we have not driven the truck in over a year) because of a faulty part that the company will not own up to. PLEASE have MOPAR/RAM/Chrylser own up to this faulty part and issue a recall ASAP. When the brakes lock up and someone dies, that will be a real issue. Sincere thanks,

HYDRAULIC CONTROL UNIT FAILURE. While driving I encountered an emergency braking situation (deer in roadway) I applied the brakes and they did not go into an ABS slide/braking condition and upon applying the brakes, causing the brakes to lock up and the vehicle begin to change its direction, the dash dinged and illuminated the ABS and Traction Control light. After this incident the lights continued to flash on and off even while parked, and the brakes not applied. I was able to get to my home, I attached my scanner and followed the procedures set for diagnosis coming to the conclusion that the hydraulic control unit had failed. I was able to get it into the dealer on the 14th of September and they had concurred with me that the Hydraulic Control Unit had failed. There were no lights on prior to this incident to make me or any other driver aware that there was an issue with the ABS system. Chrysler has knowledge of this for there is a TSB (S2005000004) as well as a redesign of the part, 68143491AA to 68143491AB. Per the dealer the part is on national backorder until February of 2024. The vehicle is available for your inspection for I will not take it on the road with these faults risking mine or the safety of my family or others especially with winter right around the corner.

Service Electronic Braking System warning locked in. Service Electronic Stability Control warning locked in.

ABS module has gone out 3 times since I bought the truck new. Without the ABS system working properly the stopping distance could be reduced. Dealer has acknowledged the problem, saying they had a bad batch of parts but that seems to be incorrect. Looks to be a bad design with the number of these problems on these year model trucks. The dealer has already replaced the part twice and it’s gone out again, less than a year later. Warning lamp, message, and audio alarm cycle on and off intermittent but constant through a drive.

A few months after I bought this vehicle I started getting abs and traction control lights intermittently. Fast forward a year and it has progressed. Now while I’m driving every few seconds I get and audible chime and lights on the dash. This is constant and extremely irritating and distracting. It is also unsafe. I’m constantly driving which no ABS, no traction control and no cruise control. Ram obviously know this is an issue due to lawsuits filed against them and they have done nothing to fix the issue. You cannot buy a new part to fix it because they are “reengineering” the part. It was originally supposed to be ready to ship in august 2023. Here we are in September and they have pushed the date back to February 2024. Leaving all customer drying a 2017-2018 Ram 2500 with an unsafe vehicle and no option to fix it. We also can not trade the vehicle in as the dash lights up and chimes and no dealer wants an unsafe truck that cannot be fixed. A recall is expect at the very least

First evidence of a problem had to deal with the accelerator pedal A new pedal was installed. .The engine would start but only idle, truck would not move when put into drive .It had to be towed .Then it was something about a door sensor .It was replaced .Then the brake fluid problem started. It used 2 full quarts with no drips on the floor . Now I am told that the brake booster / hydraulic system Is the problem. This truck Has only 31,000 miles ,Not driven in the winter and looks like new . I am now afraid of the safety issues associated with plowing into another vehicle in a panic stop , The truck has been in the dealer (Jeff Wyler ,Canal Winchester, Ohio ) for nearly 8 weeks . It has been promised last Friday then Tues, then Thursday. Today is Friday and the service advisor (Jay or Joey) are not returning my calls. Please let know what I should expect .

ABS AND TRACTION CONTROL LIGHT ON. THIS IS A WELL KNOWN ISSUE WITH THE RAM 2500 YEARS 17-18. I PULL A TOY HAULER WITH 2 MOTORCYCLES IN IT. THIS IS A 28 FOOT TRAILER. I DID NOT NOT GET IN AN ACCIDENT BUT I HAVE NO TRACTION CONTROL OR ABS AT THIS MOMENT. TIRES WILL SPIN VERY EASILY IN THIS TRUCK IN THE RAIN. HAD THE BACK END STEP OUT LEAVING WORK CROSSING TRAFFIC AS I HAD NO ABS INTERVENTION AND IT WAS COMING OFF OF A BIG HILL. THE DEALER SHOULD BE COVERING THIS. I HAVE AN APPOINTMENT TO HAVE IT LOOKED AT AND WAS TOLD THE ABS UNITS ARE ON BACK ORDER TILL FEBRUARY WHICH MAKES PERFECT SINCE BECAUSE THEY ARE ALL FAILING. HOPEFULLY BY THE TIME I HAVE MY APPOINTMENT THIS WILL BE COVERED AFTER READING ABOUT THE LAWSUIT AGAINST THEM. APPARENTLY THEY RECALLED THE 19-22 VEHICLES FOR THE SAME ISSUE.

In July of 2020 the service alarm went off for my electronic braking system and ABS. I took it to the local RAM dealership and they replaced the Hydraulic Control Unit for the ABS System (not covered under warranty). Now, in August of 2023 I am again having the same service alarm for the electronic braking system and ABS sporatically occur. I have not yet taken it back to the dealership, but in my search on YOUTUBE, this appears to be a systemic problem that the manufacturer is not addressing.

The ABS light came on and went off intermittently, which also disabled the cruise control when the light was on. Eventually the light stayed on. Most recently the start button quit working properly. We have had it at the dealership twice with no results. We have talked to the dealership many times and been getting the run around. The latest was today and was told the parts are back ordered until 2024. They have not given us any paperwork because we do not have to pay. We also have and had the radio (main computer) replaced a couple of times and the screen still blinks randomly.

ABS and Electric Braking System - multiple failures.. 1st time system failed at around 24k miles, was reported and fixed under warranty, 2nd time same system failures at around 76k, same errors and same results.. will have to be repaired under owners costs.. Seems this is a 'known issue with a NTSB" but Ram still not owning the issue.. This part plays a huge role in the safety controls of the truck.. They are designed and built to pull heavy loads and the braking and traction controls play a huge role in the safety traveling of these vehicles..

The ABS warning light comes on and off continuously while driving the truck.

My truck has had a recall done on the ABS system. After the recall I had another problem with the ABS system where the ABS and traction control warning lights and chime came on and then off. This condition was very distracting while driving!! It eventually stayed on all the time. My cruise control did not work and I imagine the ABS braking system didn't work. All the time the dealer was saying there were no parts. I found another dealer and had to wait a few weeks and they replaced the ABS HCU and hydraulic unit. This was in 2022. It is now 9/13/23 and it is starting again!!! I am going to take it back to the dealer and hope they finally will resolve the problem. ABS brakes have saved many lifes. This problem needs to be fixed. There are countless concerns on the internet of this problem with RAM trucks, apparently 2017 and 2018 are the most affected. Please put some fire under FCA/RAM and help get this problem repaired.

ABS/traction control failure. This also disabled cruise control causing rapid deceleration at set highway speed. Getting repeating chime and check ABS and traction control warning messages. ABS module and HCU were replaced under warranty at under 11,000 miles for same symptoms. Truck now has just over 45000 and read ABS codes indicate that part has failed again. Part seems to be backordered or unavailable from dealers.

ABS/traction control sensor issue. I believe it to be a faulty sensor or sensor connection issue which is causing my service brake light to chime and light up at every bump in the road. While driving even just a short distance my service brake light/alert chime goes on and off sometimes every 2-3 seconds and while driving on the freeway my cruise control disengages every time the brake warning pops up. Upon researching this issue I've found thousands of Dodge Ram owners complaining of the exact same issues and dealerships are suggesting they know nothing about this problem.

ABS system failure, recirculation pump failure, code C0020, Ran off road while ABS and traction control was off during wet conditions. Unsafe to drive due to safety failure on ABS.

Lights on won’t go off

FOR THE PAST MONTH A WARNING LIGHT ILLUMINATES AND DINGS CONTINUALLY INDICATING AN ABS FAILURE AND NEED FOR ELECTRICAL BRAKE SYSTEM SYSTEM REPAIR. I CALLED THE LOCAL DEALER THAT WAS RUDE TO SAY THE LEAST AND INDICATED THEY KNOW THIS ISSUE WHICH IS VERY COMMON AND REQUIRES PARTS (ABS CONTROL UNIT HCU-HYDRAULIC CONTROL UNIT) THAT ARE ON BACKORDER AND WILL NOT BE AVAILABLE UNTIL NEXT YEAR (POSSIBLY FEBRUARY OR MARCH). THEY STATED IN CASE OF EMERGENCY BRAKING AND PARTICULARLY ON WET PAVEMENT OR GRAVEL THE BRAKES WOULD FAIL AND THE TRUCK SHOULD NOT BE DRIVEN. I SEARCHED THE WEB AND CLEARLY THIS IS A WIDESPREAD PROBLEM OF A PART/SYSTEM DEFECT. I AM LEFT IN A POTENTIALLY HAZARDOUS SITUATION WTH NO RECOURSE AND NO VEHICL TO DRIVE. I APPRECIATE ANY HELP YOU CAN GIVE ME AND OTHER RAM OWNERS.

Reoccurring Electronic Brake System Failure message along with ABS and Stability Control faults, dealer unable to fix due to supply issues. Ram is supposedly waiting on a redesign, but until then I have a safety compromised vehicle where abs and traction control don't work.

ABS , traction lights are on and cruise control , ABS and traction control doesn’t work. Safety issue. I understand that there is a recall on 2019 , 2020 models and wondering why the 2018 ram 2500 are not included in the recall .seems like a common problem says the dealership.

While driving on a smooth paved road the service anti-lock brake system and service electronic brake system lights started flashing on and off. This continued for several minutes and then randomly stopped. On my return trip home after about 10 minutes of driving on the same smooth paved road the service antilock brake system and service electronic brake system lights started flashing on and off again. Once again the service lights randomly stopped on their own while continuing driving.

My truck is at approximately 35,000 miles. It recently started notifying me that the Anti-Lock Braking System and the Traction Control need to be serviced. While researching, I noticed that there were numerous reports of drivers with the same issue on forums related to Ram trucks. It appears that this is a very common issue that has not been addressed by Ram.

Anti-loc braking system, and electronic braking system issues. Modules needed. Ram has back-ordered them for months. There appears to be a class action suit starting, What is NHTSA doing?

ABS module or HCU bad. Anti lock brakes not working. Cruise control not working. 4WD not working. Caused issue driving with a load when ABS did not engage and almost rear ended another vehicle.

An ABS system that was designed to save other people. And your life is now not operating functionably. And putting me and other people in danger. Or else why would they have made it way back in the day? Receiving vehicle message of serve ABS braking system. Code C0020-01. Dodge knows of the issue and needs to recall and repair.

Abs modular gone bad

Abs brake failure the hcu fails causing warning to service abs problem first occurred 2 years ago had hcu replaced problem is back again these hcu units were defective from the get go ram knows units are defective this is a safety issue and needs to be resolved your help is needed on this safety issue.4/12/

C0020-01. Electronic Braking System and stability control system continually go in and out of alarm kicking the truck out of cruise control suddenly. This was repaired once under warranty by replacing the hydraulic control unit at 40,000 miles and it is now doing the same thing again at 90,000 miles. This is a significant safety issue as it prevents the use of cruise control and turns off the stability control system on the truck. The parts to repair the system are not available due to them being in “Engineering Review” until 2024. The only guidance from Ram was to continue driving the vehicle until parts become available.

SERVICE ELECTRONIC BRAKE SYSTEM NOTIFICATION TURNS ON INTERMITTENTLY, CRUISE CONTROL DOES NOT WORK DURING THIS TIME

ABS module

ABS warning light goes on and off at intermittent times. Message says service ABS brake system. This truck has not been inspected yet but there is a class action lawsuit and NHTSA investigation on-going for this problem.

My 2018 RAM ABS warning indicator light goes on and off continually. It started last year but now it's on constantly. I did some research, and this seems to be a very common issue with this model of RAM truck. Unfortunately, the dealership has informed me there is no recall on the item and cost to repair are over $1,000. So I'm driving with no ABS brakes most of the time. With the light and warning noise constantly going on and off is very distracting while driving. Not a very safe problem to have while driving.
