2018 Ram 3500 Complaint Log

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

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.

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.

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.

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

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.

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.

ABS & Traction Light and ding ding, then go away for a while then it all comes back. Truck is out of warranty, so any cost is mine. They want you to pay for diagnostic even there is a code. Quoted cost was around $800 to $1000. The first time this happened the code said to replace the 4wd shift motor. Done that problem went away for awhile then came back. I am retired and these cost don't fit in real good. We purchased the truck new. I have read that this problem is not new, just ongoing. When this is happening the 4wd and cruse doesn't work or shuts off. It appears that RAM isn't going to do anything until people start getting killed. Then are forced to fix it.

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?

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.

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

1. The specified vehicle has intermittent ABS/ Brake Hydraulic Control module error. The vehicle is available for inspection upon request. 2. Error causes ABS and Cruise Control to be disabled while in motion as per warning messages displayed on instrument cluser and audio annunciation. 3. Driver and passenger were endangered due to ABS malfunctioning intermittently **while in motion**. I have reproduced the problem by causing a wheel slippage on wet pavement. This will cause the otherwise intermittent problem to be asserted with corresponding error messages/notifications to be displayed on instrument cluster. 4. The specified vehicle has NOT been inspected at a Ram dealer; however, the problem seems to be well-known on 2017-18 Ram 2500's and 3500's given the amount of Youtube videos on the topic as well as the amount of discussion on online forums such as [XXX] . 5. This 2018 vehicle has approx 43000 miles on it. The described problem was not detected until about 3 months ago (approx 8/2024). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

We have been waiting for almost two years for the traction control and ads break repair. When will something be done about this recall not being repaired?

My 2018 Ram 35000 with only 33,000 miles has recently been providing numerous ABS and Electronic Braking System warning lights. They are intermittently and can sound several times continually or they can go for several miles with no alarms. It appears that this is a well known issue with Ram trucks that I believe the manufacture should repair as it is a safety concern.

The contact called on behalf of the owner of the 2018 Ram 3500. The owner received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic). However, the part to do the recall repair was not available. The contact stated that while driving at various speeds, the check engine and ABS warning lights illuminated. In addition, after the ABS warning light illuminated, the cruise control and the traction control failed to function as needed. The vehicle was taken to the dealer. The dealer informed the contact that the part was available at the dealer; however, the manufacturer refused to pay for the recall repair. Most recently, the traction control failed to function as intended. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 150,000.

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

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

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

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

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

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.

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!

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.

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.

The contact owns a 2018 Ram 3500. The contact stated while driving 65 MPH, the ABS warning light illuminated. The vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); the VIN was included, but parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The failure mileage was 34,000. VIN tool confirms parts not available.

My anit lock brake warning keeps going on and off

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.

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.

ABS and traction light on dash. At 72,000 miles, I'm unable to drive my truck due to ABS module back ordered. Either I drive it and take a risk, or let it sit and rot. Purchased brand new in 2019. I have paid 965.00 monthly since 2019 and still owe 12,000 for a vehicle I do not feel safe in. I can't send a invoice, because the mechanic is not able to fix due to lack of parts.

The vehicle is displaying a "Service Electric Brake System" message indicating failure of the HCU and ABS system and possibly affecting stability control. There is a lengthy history of this issue with the 2500 and 3500 trucks but no fix, resolution or recall appears to be available for this issue.

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.

The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the ABS, traction control, and HCU warning lights illuminated, and the AWD feature was inoperable. The contact received notification of NHTSA Campaign Number: 24V896000 (SERVICE BRAKES, HYDRAULIC); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was 63,000.

For 18 plus months the lights, alarms stay on due to the HCU recall, this issue also causes the cruse control not to work. Alarms and lights are a big distraction when driving Ram has yet to correct this issue with no time line given I need help Thank you

Loss of ABS braking and traction control

The contact owns a 2018 Ram 3500. The contact received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The local dealer was contacted but the vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that while driving on a local roadway and descending a hill, the vehicle unexpectedly shifted out of gear, and the contact temporarily lost control of the vehicle, which then independently accelerated. The contact subsequently regained control of the vehicle. Additionally, the ABS was inoperable during the failure. The approximate failure mileage was 36,000.

The ABS warning light illuminates, and warning chimes continually go off as I drive. I've been literally waiting years for a fix (since 2020). The dealer says the parts are unavailable. In the meantime, I intermittently have no ABS, cruise control, or trailer brakes. This is concerning because I tow a heavy trailer. It is very easy to lose control if you're not careful.

Service abs/ service electronic brake system/ traction control alarm flashing on/off intermittently with no specific times or conditions. This first happened in may 2024 on a 6 hour road trip. Occasionally I can take it on a short trip and it may not flash the message during that trip and at other times it is constantly going on and off. I have not had this looked at by the dealer. I have read the codes using my personal scanner and it shows C0020-01 (Active) ABS Pump Motor Control- General Electrical Failure. I do not drive this vehicle daily and I can not relate it to wear and tear because the vehicle only has 23,900 miles on it.

ABS light started flashing and cruse control quit working. Scanned for codes and found P0020-01 ABS control module. Searched online and found 1000's of cases of problems related to this.

ABS failure light started coming on along with service electronic brake system. Dealer shows I believe code 0020 which is the ABS/HUC pump failure. Dealer says seeing it quite often, hard to get parts as each part is allocated and tested before leaving. So I either stop driving it and wait for parts which seems to be a known issue or keep driving and hope for the best while the engineers try to figure out what is going on. Currently it is sitting at the dealer as they try to get the part before we leave on a trip at the end of the month.

ABS AND TRACTION CONTROL LIGHTS ON DUE TO FAILURE OF ABS MODULE AND PUMP. NO ACCIDENT BUT FEEL THERE COULD BE A PROBLEM IN THE FUTURE CONSIDERING THIS IS A SAFETY ISSUE

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

the following messages appear randomly and frequently resulting in a dash lamp/ chime and loss of cruise control electronic braking system fault. HCU electronic error (stored code) many reports of the same problem I've read about.

I WAS PULLING MY 5TH WHEEL TRAILER DOWN THE INTERSTATE, AND MY ENGINE FAN CAME ON "HI". THE SUCTION FROM THE FAN CAUSED THE RUBBER FAN SHROUD TO BECOME SUCKED INTO MY FAN AND IT CUT IT INTO LARGE PIECES. THOSE PIECES WERE THEN VIOLENTLY THROWN INTO THE RADIATOR AND PUNCTURED IT RESULTING IN LOSS OF ALL ENGINE COOLANT. THIS IS A KNOWN AND DOCUMENTED MANUFACTURER DEFECT RANGING FROM 2014 TO 2018.

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. Good Morning Mr xxxx, As of 06/26, No new update Part: 68228991AD Module Order: xxxx Per CLIMS: Part STOCK is under QUARANTINE pending quality / engineering review and inspection. Working to obtain timing on resolve to predict allocation and shipment to DLR to fulfill No firm ETA to provide at this time. Pending response from SPLR / PKG Working to improve xxxxx Case Management 844-378-0575 Ext:4063199 My dealer said, be lucky if they ever have parts for a permanent fix. I can’t haul anything or use cruse control. Error lights keep popping up sporadically with dinging sounds, driving me crazy. It is "Service Electronic Brake System" with continuous ABS and STC fault warnings. This truck is dangerous to drive, a recall is a NO BRAINER!!!! I am writing for three reasons. 1. You need to get our dealer the parts now so we may have a safe vehicle, or 2. replace this truck with a new one if you cant repair ours ASAP, and 3. To make sure I have this all documented in case of any serious accident where you will have to assume all liability and responsibility if this occurs due to your lack of ability to repair this safety system.

Abs module keeps on going out in many rams from 2500 to 3500. Making a alert sound about every 3 seconds making distractive driving I am currently #28 in line for the part in a small town and it's been 2 months now. They need a recall on this. They are being negligent by not saying there is a problem.
