2018 Ram 3500 complaints

Intermittent chime and warning that anti lock brake needs servicing. Cruise control does not work when notice is displayed and chiming. warning comes and goes randomly After researching this problem it appears that this is a regular problem on this year ram truck I will report and take to the dealer if problem remains.

Failed abs module and/or hcu. Truck is available for inspection. Loss of abs and traction control causes loss of control of truck in wet conditions when stopping or cornering. Hcu was replaced by dealer 10/12/21 @ 20,109 miles due to code c0020. (Abs pump control motor general failure) Same issue/code @ occured again @ 47,000 miles. Have not been back to dealer as the truck is out of warranty and the cost is almost $2000 for the repair. Service Abs/traction control/ electronic brake warning lights constantly go on and off and eventually stay on. This causes abs and traction control to be unreliable and is extremely dangerous on wet roads and also dangerous to other vehicles on the road.

Antilock Braking System failure with my 2018 RAM 3500 Dually. The vehicle’s anti-lock brake system error, also causes the cruise control and traction control systems to become inoperable. The old HCU is currently on the vehicle for inspection by additional parties. This issue increases the risk to safety to vehicle occupants and public, for control of the vehicle, under wet or slick road conditions. As mitigation, while dealing with the defective part/system, drivers need to remember to operate vehicle differently in adverse conditions. Both a local shop and the Doge/RAM dealer confirmed the HCU needed to replaced. RAM MOPAR would not sell the HCU part to local shop for quick repair. Then I waited 5 weeks for service appointment at the local Dodge/RAM dealer, 1 week for estimate, 1 week for HCU part to arrive and schedule appointment, then finally 4 weeks to get appointment to (hopefully fix the problem, plaguing RAM owners due to the defect). I already had the unit replaced at 41K under warranty by the Dodge/RAM dealer, but unfortunately I am 1K miles out of warranty (75,000mi) on the second event, and estimated to cost me ~$750. The defective Hydraulic Control Unit, HCU, started to fail around July 1, 2024 sending service messages intermittently, and progressively got more as time went on. Both a local shop and the Doge/RAM dealer confirmed the HCU needed to replaced. The old HCU is currently on the vehicle for inspection by additional parties.

ABS/ HCU ISSUES- BLINKING LIGHTS, Hendrick Dodge service in Cary, NC has the 2018 Dodge Ram 3500 in for service to replace the draglink that was another recall for 2nd time to replace the draglink this time. I know there is class action lawsuit 2023 file against FCA on the ABS modules and HCU's for 2017 &2018 ram 2500 and 3500 trucks.

The contact owns a 2018 Ram 3500. The contact stated while driving at various speeds or while at a traffic light, the “Service ABS system Soon” message was displayed. There was an abnormal dinging sound detected. The ABS and traction control warning lights were illuminated. The vehicle was taken on three occasions to the local dealer, where it was diagnosed that the control module and the anti-lock braking system needed to be replaced. The vehicle was repaired, but the failure persisted. The manufacturer was not contacted. The failure mileage was approximately 24,365.

The contact owns a 2018 Ram 3500. The contact stated while driving 55 MPH, the ABS failed to engage. The brake warning light was illuminated. The contact stated that a dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 77,000.

We purchased the vehicle as a back up for when my husbands every day work truck is in need of service. The truck is from 2018 and now has about 40,600 miles because it isn't used often. The truck would start flashing a light saying service anti-lock brake system sometimes during the time the light was flashing it felt like the brakes struggled a little. We have sent it in to get repaired and they quoted us over $1300 of repairs because it needs a an abs module and pump.

Continuous intermittent Service ABS System / Service Brake System warning light and audible warning chime

Abs braking not working , HCU failing pump. Ram will not cover this very critical system which faulty part due to no wear from use .

Truck wouldn't stop antilock brakes did not work. Been trying to get 68347098ab and 68143491ab for the last 3 years from ram but been on backorder for that long. Was going down gravel road and trying to stop but wouldn't one wheel locked up and truck went into ditch smashing fender and hood.

Intermittent issues with the cruise control system and the ABS electronic braking system. The lights will flash on and off and the beeping is constant. If beating on the side of steering wheel will allow you to turn cruise control, then the ABS system will be okay for unknown reasons it will start flashing again and cancel the cruise control and the system will start flashing check the ABS electronic braking systems.

Lights and chimes constantly signaling trouble with ABS/Traction Control system. OBD 2 indicates ABS Module failure but have read online it could also be HCU pump, a connection problem or a combination of issues. At this point the warning lights are on constantly while driving. No cruise control available. Talked to dealership and informed they are aware of the issue as it is wide spread with several models. Long back order and wait times for upgraded parts. Seems clear it is a safety issue.

No antilock brakes for 3 years. The parts have been on back order for 3 years and still no sign of when be in. Always in back of mind if brakes will work or not when trying to stop truck.

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

We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes out while driving this vehicle. It is available for inspection upon request. When will there be a repair for this?

A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 —> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the NHTSA to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn’t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.

The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the "Service ABS" message was displayed. The traction control and ABS warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the ABS control module. The vehicle was not repaired due to parts not being available. The manufacturer was not notified of the failure. The failure mileage was 40,000.

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.

Abs and electronic control system lights intermittently come on and off constantly and have been for 25,000 miles. When it started happening Chrysler knew what the problem was hcu and abs module is malfunctioning but unfortunately no parts were available and couldn’t tell me when they would be available. I’m just now putting in the complaint due to just learning about this site.

The abs light and the traction control light come on and you get the code for a bad abs pump and hcu. Codes are C0020-01 and code C0020-16

HCU / ABS light lmaps started flickering and now stays on I only have 42k miles on this truck. When I researched come yo find out everyone is having the same problem with the 2017 and 2018 this is a safety problem that needs to be fixed. I was on a wet road went to stop abs light came om I slid alot scared me to death considering I was pulling a 10k lb trailer behind me. Anytime it rains I'm scared to drive this truck rear wheels spin way too easy especially with traction control not working and I don't trust the stopping after my incident. With so many more customers having this issue please have this fixed asap make it a recall someone will end up getting seriously from this issue and many have notified this site FIX THE PROBLEM ITS NOT SAFE

The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.

The contact owns a 2018 Ram 3500. The contact stated while driving at various speeds, the messages "Service Brakes" and "Service ABS" were displayed and an alarm sounded. The contact stated while driving 30 MPH, the failure recurred and the front passenger's side wheel locked up, causing the vehicle to accelerate unintendedly. The contact was able to decelerate and continued driving. The vehicle was taken to the dealer, where it was diagnosed and determined that the ABS pump and the ABS module needed to be replaced; however, the ABS module was on backorder and under engineering review. The vehicle was not repaired. The contact related the failure to NHTSA Action Number: PE22012 (Service Brakes, Hydraulic). The manufacturer was not notified of the failure. The failure mileage was approximately 68,000.

The component that failed was a brake module. It caused the loss of ABS and TCS. The part was claimed to be on backorder, and it took seven months for the part to be replaced. This forced me to drive an unsafe vehicle.

ABS and Traction control failure. Code C0020-01. Occurs at various speeds and while stopped.

ABS and Electronic Braking control modules have not been working for 13+ months. Originally diagnosed by dealership July 2023. Been trying to get RAM / Stellantis to fix it. Been told parts are back ordered or not available due to re-engineering. Have heard there are hundreds of trucks impacted at each dealership. Why hasn’t there been a recall and why is RAM not helping me to get it resolved? Another call with them today 8/13/2024 and the dealership just needs the approval for cost for the HCU and RAM Customer Care is not responding and when they do, it takes days and no resolution.

The contact owns a 2018 Ram 3500. The contact stated that while starting the vehicle and while driving at various speeds, the service ABS and brake system messages were displayed. The contact stated that the failure recurred intermittently. The dealer was notified of the failure and informed the contact that the failure could be related to the HECU. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 52,700.

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 ABS light intermittently comes on/off. It pops up while driving, but goes away. Sometimes it goes on/off several times on short drives. I need to know if this is going to lead to an all out failure of the braking system or something else. I confirmed with the dealer, where I purchased the truck, that it's a known issue and the part is on national backorder. Based on my research, this appears to be a common issue with Dodge Ram trucks built between 2017 and 2021. I need to know what my options are since I plan to purchase the needed part(s) at my expense since my family's safety is at risk.

The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated, and the cruise control failed to activate. The dealer was contacted and stated that the failure was a known issue. The dealer stated that the ABS Control Module needed to be replaced. The vehicle was not repaired because the part was not available. The contact was placed on a waiting list. The manufacturer was not made aware of the failure. The failure mileage was 67,500.

The ABS warning system is constantly going off with dash warning lights and alarm, it turns off cruse control when this happens. The truck is unsafe with out the abs working and dangerous because it will turn off the cruse when the error is displayed causing unexpended deacceleration. This happens when ever the veh is driven over and over. I took it to the local ram dealership. They told me that they can not figure out what the issue is......They told me I have to leave the truck at the dealership for a week at my expense (gas and insurance and they would not be responsible for damage) so they could drive it around and "test" it they were very unhelpful, they said they never ran across this issue prior. They were very stubborn on the actual issue and would not answer questions In the mean time the dealer attempted to sell me an oil change and oil filter change for close to $1000.00 that they were very insistent on. (with less that 3000 miles on the current oil and filter change) so this was unneeded. They were using the fault to upsell service and no attempt to correct it.

Repeated, intermittent warning to service electronic braking system and service antilock braking system, both of which cause the cruise control to disengage. On multiple occasions, the disengagement of the cruise control has nearly caused me to be hit from the rear. Multiple forum posts indicate that this is a common problem.

Service antilock braking system and service electronic braking system along with traction control light and message flash on and off intermittently. Have had mechanic look at it and was told dealer would need to see it. Have been on a few online forums and this seems to be something that many people have had issues with. Is there any kind of recall I’m missing on this issue? Thank you

ABS service light comes on and off - this seems to be a chronic problem

Radio and back camera intermittent since I bought it new. Dealership changed it out several times and told me they are just bad radios and just wait until a recall is issued.

We receive a ABS/ECS, electronic brake control warning intermittently. This also makes the cruise control shutoff. We had the ABS control module replaced once at roughly 12000 miles under warranty but it now is giving the same warnings and the truck currently has 22000 miles on it. My dealer stated this was a known issue and stated it’s fairly common on my model truck

I have a 2018 RAM 3500 with ONLY 20,000 miles on it. ABS and HUC critical parts are faulty, and I have no way to even purchase one until a recal is issued. Class Action Says 2017-2018 Ram 2500, 3500 Equipped with Defective Anti-Lock Braking Systems. No current part that resolves this issue. Ram 2500 and 3500 pickups are unsafe because they’re equipped with defective hydraulic control units (HCUs) and anti-lock braking systems (ABS). RAM knows about it and has ALL the modules on engineering hold. These parts have not been available for almost a year. No antilock brakes. No traction control. No cruise control. 4X4 four wheel drive system is locked out and cant be engaged after this warning occurs. Here's what they are telling customers who have filed with them about this.

It is "Service Electronic Brake System" with continuous ABS and STC fault warnings. This truck is dangerous to drive, a

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.

ABS and HCU are defective , loss of braking ability in the vehicle and braking ability on the travel trailer. unable to stop in adequate distance when pulling 12000 pounds through mountains putting others at risk of collision had vehicle in for repairs three different times since 2019 ABS light luminates when system fails had vehicle in for repairs on 10/19/2020 , 2/5/2021, 6/20/2024, 7/18/2024

Vehicle produces code C0020-1 ABS pump motor control failure, vehicle disengaged cruise control unexpectedly causing rapid deceleration. Dealer states ongoing problem with 2018 Ram 3500 HD trucks

Abs lights started flashing on and off rapidly. Had same issue fixed at dealer 40,000 miles ago and now it started again seems like a money racket or something now I’m quite scared to drive it if the brakes was to lock up it could be bad

Abs / hcu has malfunctioned again, has already been replaced once around 20,000 miles now I’m around 58,000 miles and having same issues. Abs and traction control not working. In a truck with this much torque it is a serious problem. This is a well documented issue with the system and FCA should make it right. I found a video on line that explains the issue is with the brushes on the motor being held in to tightly. Should be a simple solution and is obviously a design flaw. There should be a safety recall asap. I assume that this problem happens with most of the heavy duty trucks.

ABS braking system, electronic braking system warning light and signal is coming on every few seconds when driving. This renders the cruise control to shut off when it comes on. There are numerous safety issues with this coming on and off not to mention it is annoying as…..well let me just leave it there. Have talked to dealers (2) and have been told that dodge has a fix but the parts are still on back order. I have been having this issue for about 6 to 7 months and it is making the truck undrivable for any distance at all due to the nuisance alarm every mile or so.

ABS system - flashes on and off dash, ABS has been inspected by dealership. Dealership said, could replace ABS but it could very likely have the same issue due to part malfunction. This malfunction causes- no cruise control, no traction control, sounding and lighting up on dash constantly.

Pulling a travel trailer in the mountains on vacation this month my Service ABS light started coming on and off intermittently and the alarm would sound each time. Each time my cruse control would turn off and I wasn't sure if my emergency ABS brakes were going to work, or not, if I needed them to pulling my trailer with my wife in the truck. I was 1,500 mile away from home and this created a stressful circumstance for me the rest of the trip. Upon arriving home, I discovered on the web that this is a know problem with Dodge RAMs of this year model. I also saw recall notices associated with 2018 models, just one year younger than mine with the exact same symptoms. Obviously, this problem didn't get fixed for the 2018 model year. I am quite concerned that my truck may not be safe and the ABS problem needs to be addressed. I am going to pay to have it fixed, but I feel confident that a recall notice needs to be executed, and executed NOW so others dont't have to die from a problem that was known and unaddressed. Thank you. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Abs service light stays on and dings. service electronic brake..

The message “service electronic braking system” and service antilock brake system” periodically displays on the driver information screen. If I’m using cruise control when the message comes on the cruise control abruptly disengages causing a lurching slowdown. Often times it chimes and the message displays and disappears and comes back on and off numerous times.

It appears that Ram years 2017-2018 have a known problem with the ABS pump. I have my 3500 ram in the shop now with only 30,000 miles and they are telling me the ABS pump needs to be replaced at a cost of roughly $1200.00. It is my understanding that there is a class action lawsuit and wondering why these vehicle have not been re-called? Major safety issue!

Vehicle was purchased used in Feb 2024 with 77000 miles. As I was leaving the dealer (Carmax), gauge cluster lit-up with Service ABS System and chimes. Spoke with dealer and they said to take it to Ram Dealer for diagnosis. Unit was diagnosed as needing a new ABS electronic AND hydraulic control module. Dealer was unable to get parts due to issues with FCA and parts not being available. Parts were on backorder until June 204. Continued driving vehicle, with ABS light coming on/off and ABS intermittently working and not. In June 2024, spoke to Ram Dealer, and FCA is saying I have to get the Electronic module replaced first. Ram Dealer replaced this on Friday 6/21/24 and things seemed fine. About 50 miles after picking up the truck (Saturday the 22nd), while towing my 20000 pound trailer (with my wife/kid/dog inside) the vehicle started losing power while on the freeway. I was able to get the vehicle to the shoulder and the hydraulic brakes on the truck were fully locked up. I had to put the vehicle in 4-lo to overcome the brakes to get the truck separated from the trailer so it could be towed to the dealership. The dealer has 3 other 2018 ram trucks on their lot with the same issue.

ABS/Service Electronic Brake Control and Cruise Control lights constantly flash and chime while driving. Have been told that replacements parts have been on back order for over a year now. Any help will be appreciated.
