2018 Ram 2500 complaints

ABS and Traction Control warning lights randomly and routinely illuminate causing loss of ABS braking and traction control, and loss of the cruise control function.

ABS light comes on screen along with traction control. Immediate loss of cruise control while traveling 70 MPH pulling 10,000 lbs on a highway. If brakes go on that everyone's safety on the road is at risk. I have not had it to dealer but have had a mechanic put his code reader on it. Warning lamps for this were the ABS light and traction control light.

ABS and Tracton control

Beginning in October 2022, the vehicle began displaying "service anti-lock brake system" along with a chiming sound and the traction control light comes on. Cruise control is disabled when this is displayed. I went a dealer while out of town and they said they were well aware of the problem, but the part is unavailable. When I returned home I went to my local dealer and they confirmed being aware of the problem in this year/make/model vehicle, but the part was unavailable. They stated the part would be available in August 2023. August is here and the part is still not available. This is an inconvenience due to not being able to pull my travel trailer or any trailer. This is also a safety concern since I don't have anti-lock brakes. This vehicle has 39000 miles on it. Bought new and sits in a covered garage when not in use.

ABS and traction control lights warn on dash and chime. Very intermittent and my truck only has 14,749 total Miles on it. I understand most of us with 17/18’s have this issue. I don’t feel safe having intermittent use of proper braking as we pull trailers with this vehicle. It’s the entire purpose we bought it. Dealer will not repair under warranty. Need a recall. Repairs cost thousands on these low mile like new trucks.

Anti lock brake system failure, has been inspected by dealer and at dealership now, unable to repair as parts are not available for replacement. The dealership will not even try to put thru extended warranty really be hush hush about this issue. The vehicle can be inspected anytime. There where no warnings signs just started one day with the messages and lights flashing. This should be a recall before total brake failure.

The service electronic braking system and service antilock brake system are having intermittent flashing sometimes it stays on the whole drive. When it does this sometimes the brake pedal will go past the normal range for braking and go almost to the floor before it starts to engage the brakes. After reading several forms this seems to be becoming a common thing the fix is the ABS module and the hydraulic control module. What component or system failed or malfunctioned, and is it available for inspection upon request? Yes these parts are available upon request they are still in my truck. How was your safety or the safety of others put at risk? Brakes are not properly working could result in an accident with just myself or many others as I drive mostly highway. Has the problem been reproduced or confirmed by a dealer or independent service center? No it has not been reproduced or confirmed by the dealer. I seem to have a lot of incompetent dealerships/mechanics through my dealings with them having mis-diagnosed my other vehicles consistently. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has not been inspected by anyone. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes there are warning lamps, messages indicating these issues. There was no other problems prior to the failure. I believe it started on 27 July 2023.

ABS failed, cruise control and traction control are inop as a result. The risk is loss of ABS when traveling, especially on wet or snow and ice covered roads. It has not been inspected by a mechanic. The failure light is on in the dash cluster and I have clearly lost traction control and cruise control. This began on July 31, 2023.

Warning lights for service ABS system and service Electronic braking system started coming on intermittently sometimes staying on for extended periods. While the warning lights are on I loose ABS braking controls which could cause the brakes to lock up in an emergency braking situation causing the lose of control that would effect my safety and the safety of others with me or in the emergency situation. I also loose my cruise control function. Code for the alarm is C0020-01 (ABS pump motor control electrical failure).

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE is the code that came up after the dash start flashing between service ABS and service electronic brake system. The TSB says to replace the HCU and the ABS module after checking each one. I wasn't driving far, so it did not affect my safety. I have parked the truck until I can get it fixed. The problem was identified by using a friends code reader and researching several online forums. It has not yet been inspected by anyone else as I have been trying to find the parts and they are on national back order. The one dealership stated they are on national back order until FEB 2024 due to engineering review. Prior to the warning lamps, I did notice that it felt like my front driver side brake was holding the rotor after I would release the brake and start to accelerate.

The contact owns a 2018 Ram 2500. The contact stated while reversing out of a parking space, the "Service ABS System" message was displayed. The vehicle was not diagnosed or repaired. The dealer was not contacted. The manufacturer was not contacted. The failure mileage was approximately 68,000.

My vehicle and hundreds of other owners are having bad HCU/ABS units that turn OFF the ABS and traction control on our ram 2500's.

ABS warnings on dash. Error code c00020-01. Traction control, cruise control disabled.

Abs/ traction control light comes on and off lose all cruise control. Get code c0020-1.

At around 50,000 miles the ABS light started coming on. This affects traction control and speed control. Dealer said it was the ABS Control Module and is a known issue but not a recall. Finally repaired at my cost of $ 1,103.32. st 57,377 miles on 9/13/2022. Less than 12 months later it is doing it again on 7/29/2023 at 69,649 Miles. This seems to be hazard as the ABS does not work or traction control. Also cuts off the cruise control when it occurs.

ABS modules and hydraulic control unit (HCU) module failure with around 60,000 miles on the truck. My antilock brakes and traction control will not operate. The dealer has confirmed this is the issue. The lights were flashing on and off and finally just stayed on

The abs pump and module are bad and there is no replacement parts available through ram. The truck only has 32k miles. They say the parts are on back order. The truck has no abs function nor does it have vehicle traction control. This should be a recall as it’s happening to thousands of trucks. This is a blatant safety violation. Yet the new trucks are still being built with these parts that are somehow not available.

Intermittent Abs Failure. Kicks off cruise control and looses ABS brakes and traction control. Very dangerous. Lost this ability while pulling my RV Camper on wet roads. Went into other on coming lane do to sliding and skidding. I guess this is a very well known issues with no recall or information from Mopar\ Ram to the owners. This almost killed me My wife and my 3 year old grandson.

Lights keep coming on for ABS System Check and Electronic Braking System check. Doing research online there are thousands of ram 2500s with the same issue. They keep appearing and then disappearing starting happening July 24th 2023 at around 57,000 miles. I have a appointment with the dealer set up but they can't get me in till August 16th. I'm worried while towing my camper or driving with my family our breaks won't work due to a known issue with these trucks.

Driving home from work, ABS and traction control light and warning started to go on and off nonstop every 2 seconds or so. No bumps on the road or excessive turning just a straight highway.. will contact dealer today for any recalls but I don’t see any open.

I WAS DRIVING DOWN US 19/27. THE ROAD WAS WET AND A DEER RAN OUT IN FROUNT OF ME. WHEN I APPLIED BRAKES MY TIRES LOCKED UP AND I SKIDDED OF THE ROAD. MY ABS LIGHT STAYS ON AND EVERY TIME I TAKE TO THE DEALER TO HAVE IT FIXED THEY TELL ME THEY CAN NOT GET PARTS. THE TRUCK HAS BEEN DOING THIS SINCE I FIRST BOUGHT IT. AT FIRST IT WAS INTERMITTEN BUT NOW THE ABS LIGHT STAYS

The contact owns a 2018 Ram 2500. The contact stated while driving 60 MPH, the ABS warning light started flashing. The vehicle was self-diagnosed by the contact, and it was determined that the ABS pump and module needed to be replaced. The vehicle was not repaired due to parts not being available. The dealer was contacted and stated that the ABS pump and module were not available, and that the warranty had expired. The manufacturer was not contacted. The failure mileage was 90,000.

My 2018 Ram 2500 6.4l is experiencing intermittent ABS, traction control, electric braking warnings on the dash which affects cruise control once alarm is active. This issue seems to be globally.

First the abs module failed then the abs hydraulic control unit failed. It has been over a year and no part is available.

Consistent warning stating, "Service Anti-Lock Braking System" and "Service Traction Control System" from the vehicle. While this warning is indicated by dinging tones, text displaying in the vehicle information screen, and lights lit on the dashboard, the ABS, Traction Control, and Cruise Control Systems do not function. This is a severe safety risk as if this occurs while driving your cruise control immediately shuts off and if driving in slick conditions you no longer have anti-lock brakes, nor traction control. This is apparently a known issue of Fiat Chrysler on the 2017-2018 model year vehicles where the HCU (Hydraulic Control Unit) needs to be replaced which will remedy this issue. The parts however seem to be in very short supply and not all vehicle mechanics can make the repairs as I am being told you need specific software to reset the system once the HCU has been replaced. This is estimated to cost between $1200-1800 to have repaired. I have reached out to Chrysler Cares and they advised me to take my vehicle to my local dealer for repair and advised there is no warranty, nor recall in place to cover these costs.

ABS/HCU is constantly failing causing my breaking, traction control, and cruise control to fail.

Had to make a hard stop, now ABS light is on, lost cruise control and traction control. Part is on world wide back order, sometime next year, reading many issues with this year abs system.

Vehicle pulled out from parking lot in front of my truck. I had to hit the brakes very hard and they took longer than normal to stop. Luckily I was able to avoid the accident by going into another lane. Immediately after the abs and stability control lights started flashing and a “service abs system” and “service electronic braking system” messages started. They went away shortly after but since then intermittently sound a warning. When this happens cruise control disengages. Took the truck to the dealer on 7/26 and was told it needs a new hcu abs module. The part is backordered until at least February of next year.

Vehicles touch screen becomes unresponsive to touch and skips around screen turning items and censors on and off while driving. Seat heaters have turned on and off on boiling hot days, radio stations switch back and forth, volume has gone up and down, parking censors have been turned on and off while driving, radio has called random numbers and people while driving and while waiting for truck to prime and start. The problem has progressively gotten worse and skips around more with every day that passes. Vehicle has been to the dealership twice for this issue. The dealership said it has become a common problem with the touch screen for this vehicle and doesn't know why it's not a recall. This is a huge distraction and $1800 replacement which is not an easy random add to a budget, meaning most will deal with the distracted driving and probably cause and accident. This will not let me submit the video and pictures I have in the formats requested. Please email me and I will send them.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds with the cruise control activated, the cruise control erroneously deactivated causing the speed to be reduced. During the failure, the ABS and traction control warning lights illuminated. The cause of the failure was not yet determined. The local dealer was contacted regarding the failure. The manufacturer was not yet contacted. The failure mileage was 101,000.

ABS light turned on on the dash. Next a warning that the park sense, ABS, four wheel drive, and Cruise were disabled. Had Diagnostics run and found that the vehicle ABS is logging C0020-01 and C0020-16. Case number S2005000004 from STAR showing this to be a known issue. Contacted every dealership within 100 mile range and the needed part of an ABS HCU is unavailable until at least February 2024. Contacted Stellantis Customer care and they will not assist unless the vehicle receives an official diagnostic from a dealership that will cost me at least $150 and they will not assist with replacing the part or even supplying the part so there was no gain from having the diagnostic officially done at a RAM dealership. Well known issue per every dealership and many online forums. No assistance from RAM/Stellantis at all.

ABS pump motor control: apparently this is a major problem according to dodge bulletin boards. The replacement part mopar was shipping was defective so they made a updated part that is nearly impossible to get nobody has any stock. Subsequently everyone is driving around with a Faulty ABS system. This is very DANGEROUS. Some people are stuck because the can’t pass inspection for registration purposes with the fault light on.

Vehicle receives service electronic brake system. HCU and ABS module seem to be the issue. Cannot drive more than 20 mph without message saying service is needed. It is constant up to 80 mph. Vehicle is parked due to safety reasons.

Message comes up to "Service electronic braking system." Code found was C0020-01 (ABS pump motor failure). Couldn't order part due to engineering review. Truck only has 20,400 miles. This part cannot be worn out. Should be a safety recall.

ABS Module and HCU Failure. No ABS or Traction control which could cause the driver to lose control of the vehicle. There have been several complaints filed but no recall issued. The same part (same part numbers)was recalled for 2019 and newer trucks.Service brake and traction control system lights on. Parts on extended back order.

ABS / Traction Control turns on and off intermittently without warning when this happens the cruise control turns off creating sudden loss of speed control

Loss of abs, cruise and traction control randomly, Abs code -C002001 After search seems to be common issue on 18 rams 2500s

At Around 44k miles the ABS and traction control light started coming on along with the warning chime. Brought truck to the dealer for diagnosis and they said it needed a ABS hydraulic control module, P/N 68143491AB. I ordered the part but dealer stated that so many parts are defective that part is back ordered at least 4 months. I have no choice but to drive the truck with defective ABS module.

The antilock /traction control warning light and alarm is going off in my truck. I took it to Woody Folsom Ram Dealership in Douglas,Ga . They informed me that my HCU ( hydraulic control unit) needed replacing .They said they could not even order the part until Feb. 2024. so now if we drive the truck if is less safe especially in inclement weather. This is so dangerous for the Ram company to not have the parts available especially for parts concerning the safety of their customers.

The Traction Control and ABS/EBS sensors have failed on my truck. The dealer states that I need an HCU and ABS module in-order to correct the problem, however because the vehicle was made in Mexico the replacement parts are not available.

8 month ago my abs and traction control light and warning bazzer came on. i immediately took vehicle to local ram dealership where i bought in it new. they done diagnostic test and told me it needed a new abs hydraulic control unit . i was told that no parts where availiable at this time and it could take 6 to 8 months to get parts. i am still waiting for parts to arive and it would cost about $1400 to fix. this truck only has 25.000 miles on it. also was told it would be ok to drive it but i am not so sure about that since the antilock brake system is not functioning.

Antilock braking system and HCU failed. Causing loss of antilock brakes and cruise control. M multiple warning lamps flash on my dash intermittently. My truck is now unsafe to drive due to lack of proper braking. This issue has been both confirmed by the dealer and an independent mechanic. Part is backorder due to numerous vehicle having this issue> recently the availability of the part has now changed to February of 2024.

ABS module and pump failed at 65k miles. Lost braking performance and stability control. Confirmed by ram dealership. Parts are on nationwide back order.

ABS and Electric Braking System Failure

ABS light comes on frequently and disables the ABS and cruise control. I dings each time and does so frequently when I hit a bumpy road. Ram says the parts are back ordered and none are available. This should be a recall due to the anti skid control not working properly.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the vehicle drove over a bump in the road, and the ABS and traction control warning lights illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the ACU, but the part was not available. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 33,000.

2018 RAM 2500 6.7l service abs system and service electronic braking system warnings on dash. Took vehicle to mechanic shop and scan showed code C0020-01. Symptom/Vehicle issuse: C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. Replacing the HCU and ABS Module seems to be the fix. I bought the truck as a hauler for 5th wheel camper and do to abs and traction control failure it can be extremely dangerous to drive.

Driving, hit 40,5xx miles and ABS and traction control light was flickering on and off. Kept getting warnings to service ABS and Electronic Brake System. After 25 miles of on and off flickering and chimes which were extremely distracting, it turned on and stayed on permanently. I do not have ABS, Traction control or cruise control. This is a known issue with the 2017/2018 models, and Mopar does not cover it even though it should be a recall. Thousands of people are having this issue, and dumping thousands into it all for it to just break again in 10/20k miles. The ABS modules are complete junk

Vehicle: 2018 Ram 2500, mileage 35171. Beginning in April 2023 the ABS and Traction control dash lights would intermittently flash while sounding an alarm. The message on the dash states "Service Anti-lock Braking System" and "Service Electronic Braking System." This creates the issue of losing ABS and traction control while disabling cruise control. As time progressed it would become more frequent and would more prominent during extremely humid or rainy weather. First call to dealership was told "We can only diagnose IF the vehicle is demonstrating the issue." At that time I indicated to the service tech that there are numerous national forums with the exact same issue. Truck was brought to dealership for official diagnosis: $179.00 diagnosis fee; $411.70 Labor to remove and replace HCM; $262.00 HCU (Part # 68143491AA); 447.50 labor to remove and replace ABS Module; and $388.00 ABS Module (Part # 68347098AB). Service tech advised me that all parts are on back order and I could possibly be without the truck until mid/end of August. This is an issue the manufacturer should be obligated to correct.

Hello, I have been having issues with my 2018 Ram 2500. The Service Traction Control and ABS lights on the dash have been flashing on and off constantly. Along with no Cruise Control when this happens. This has been going on now for about 3500 miles. I am still driving the vehicle due to being my only work truck. I have been doing some research along with talking to the Ram Service Departments and have noticed that this is a very large safety problem that is highly known about that is not being taken care of. Even the service manager I had spoken with is amazed that this has not been a recall. This should most definitely be a recall and should be taken care of before more people get injured or killed.
