ABS light is on and while driving a message appears on dash which indicates "service electronic brake system." It comes on and stays a few seconds and goes off and then comes back on. Mechanic has diagnosed and found code C0020-01 which indicates ABS pump motor control general electrical failure. This truck only has 16,000 miles on it.
2018 Ram 3500 brakes complaints
Page 19 of 23: complaints 521 to 550 of 668, newest first, as owners wrote them.
The contact owns a 2018 Ram 3500. The contact stated that the ABS and traction control warning lights were intermittently illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS control module needed to be replaced. An unknown dealer was notified of the failure and confirmed that parts were not available for repair. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 180,000.
Failure of the ABS Control Module. Warnings displayed on Dash "Service Electronic Braking System" "Service Traction Control." and ABS/Traction Control warning lights light intermittently While Driving. This happened the First time around 35,000 miles on a cross country highway trip, and has come back again for the last two weeks. around 76,000mi. Slight Research Has shown me this is a very common problem on 2017-2018 RAM 2500,- 5500 trucks.
On my 2018 RAM 3500 beginning on Memorial Day 2023, the instrument cluster began flashing with a loud door type chime. The cluster began cycling through messages including Service Electronic Braking System, ABS Failure, and illuminating alarms. Upon testing with a code reader I was presented with the following codes: C0020-01 ABS Pump Motor Control - General Electrical Failure and U0402-00 Implausible Data Received from TCM. Upon internet investigation, I discovered this is not an uncommon problem with several hundred reports available on ramforumz.com and other sites. According to several complainants, the repair for this will cost in excess of $2000 with one complainant stating this has had to be repaired twice as the replacement components are also faulty. This needs to be investigated and frankly needs to be a national recall on these vehicles, it is a lot more dangerous than a tailgate lock issue. I am concerned with the cost, but more concerned that replacing the noted components may not solve the issue in the long term resulting in additional costly repairs.
I purchased this vehicle new off the lot with only 11 miles. At approximately 10,000 miles the ABS system started to malfunction intermittently. System checks via OBDII scan tool indicated a hydraulic control unit failure. This part is impossible to obtain as all dealerships contacted in a 100 mi radius report a backorder with prices for repair inflated due to demand. Limited research has yielded mass complaints about this problem but no action on the part of RAM. This is my only vehicle and just like many others I cannot just park it or sell a defective vehicle without a substantial financial loss that I cannot afford. The HCU failure has caused my brakes to lock up when braking for an emergency stop. Without intervention from the federal safety agency and other government agencies, I fear there will be several unnecessary injuries or deaths due to this known and documented common failure.
The contact owns a 2018 Ram 3500. The contact stated that on several occasions while driving at high speeds, the vehicle drove over a bump in the roadway and the ABS warning light, electronic stability control warning light, and the check engine warning light intermittently illuminated but remained illuminated. The contact stated that prior to driving over the bump, the cruise control operated as designed; however, after driving over the bump, the cruise control failed to operate as needed. The vehicle was taken to Auto Zone for diagnostic testing. The contact stated that several unknown codes were retrieved. The vehicle was not repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 112,000.
In July 2022 our 2018 RAM 3500 Diesel 4 by 4 truck started having an intermittent alert. Service electronic brake system, ABS, traction control. Cruise control is disabled during this alert. May 2023 the vehicle was taken to local dealer for a diagnostic. They revealed no codes were revealed answer was to replace the ITBM at a cost of 921.00. And the diagnostic charge was 233.00. I tried to contact the dealer for further questions with no cooperation. I started investigating and purchased a code reader at my own cost. The code that showed was C0020-01 ABS Pump Motor Control-Electrical Failure. Much different than the ITBM I was told. Fiat Chrysler Automobiles put out a Case Number: S2005000004 Release Date 04/28/2020 Symptom/Vehicle Issue: C0020-01-ABS PUMP MOTOR CONTROL- GENERAL ELECTRICAL FAILURE Discussion: Basically says to replace HCU first and then ECU if code still active. So, the dealer is aware of the issue and outright lied to me. There is also an active Class Action Lawsuit for this very issue In California Plantiff James Neu. The fact that my vehicle is not in a safe working condition with this faulty part. The fact that the Dealer is lying about which part is defective and would have installed a different part than what they said the problem is. It is very disturbing that an automotive company is treating the safety of their customers so carelessly. The Fact that this is a common and widespread issue and nothing is being done to rectify, appalling. Thousands of vehicles on the road, no parts available. Action needs to be taken. Lives will be lost, severe injury, it can happen to innocent people. Please do something
Intermittent warning lights for ABS and traction control. Message to "Service Electeonic Brake System". Data scan indicated ABS pump failure. Research shows this is a known issue. Dealer can't get parts to repair.
2018 Dodge 3500 ABS light came on and disabled cruise control functions. Took to dealer and another 3rd party, both said replacement of ABS module was only solution to fix. Fairly expensive fix. It first happened around 60,000 miles sometime in 2021 and now at 80,000 miles it no longer functions. No recall appears to exist but it is a problem.
The contact owns a 2018 Ram 3500. The contact stated the anti-lock braking system (ABS) and traction control warning lights were illuminated intermittently. The contact called the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 26,000.
The ABS pump set a code c0020-01 general electric failure. Upon Inspection by a Mopar technician it was found that the pump needs to replaced. Was advised not to drive the vehicle for it was not safe because of the pump failure the abs feature of the brake system might fail. There is only 15000 miles on the vehicle.

ABS and traction control warning lights come on sporadically.
ABS faulty. No solution from dealer to correct so chime continuously, lights on dash and ABS not functioning. Part on back order with no foreseeable stock date and new parts are not correcting problem anyway, according to dealer. Here are additional notes from web: 2018 Ram 2500 ABS/HCU problem. Code C0020-01. 10/2022 Class action law suit filed in Texas for 2017-2018 Ram 2500/3500. 12/2022 the federal safety agency open investigation into the 2017-2018 Ram 2500/3500 trucks. 4/28/2020 FCA issues “Diagnostics for this DTC are currently under review. When working on a vehicle with an active C0020-01 and testing leads to replacement of both the HCU and ABS Module, order and replace the HCU first. Do not order or replace the ECU. Follow Service Information to replace and bleed the HCU. Then perform a test drive. If the DTC C0020-01 did not reset- repair is complete. If the C0020-01 did return active, replace the ECU and return the parts to FCA.” However nobody at my dealer has heard of break issues on the 2018 Ram 2500. Common enough of a problem FCA sent out communication with the dealers on how to fix this issue.
"Service ABS"; ABS & Traction Control lights & chimes come on. This is random, sometimes for hours at a time and sometimes for days without. I've researched and have found this is very common with 2016-2018 Ram trucks.
Hydraulic Control Unit and ABS Module need to be replaced for the 2nd time.
Service ABS, traction control, ESP, ABS lights come on. Vehicle constantly beeps. RAM dealer says it needs a new HCU/ABS module (on national backorder) and/or ABS pump. Second time this has happened. Vehicle now at 77k miles and it happened all over again. If this is happening regularly then something must be defective with the parts they are putting on the truck.
ABS braking keeps flashing and brakes are intermittent. The module was replaced by Ford dealer a while back. Truck only has 118k miles on it but continues to be a problems. I have not contacted dealer yet due to the time they take to do anything.
Loss of brake performance the federal safety agency action no. PE22012. Intermittent random dash warning “service electronic braking system and ABS”. Loss of cruise control and 4x4 functionality when lit as well as trailer brake control. Started Nov 2022 and currently continues. Will go weeks without problems and then problem will restart. Many issues listed on Internet forums regarding same. This should be a recall before someone towing a large trailer (as these trucks were designed) loses brake functionality due to a known problem and causes severe injury and/or death. Vehicle currently has approx. 45,000 miles. Multiple forum responses on internet have had parts replaced multiple times in similar mileage
ABS Control Module bad needs recall Hydraulic Control Module bad need’s recall Dashboard ABS / Traction Control lights and buzzers going off.
The contact owns a 2018 Ram 3500. The contact stated that on four separate occasions while driving at various speeds, the ABS system locked up the rear wheels, causing the vehicle to skid and the trailer that was being hauled to thrust around out of control. Additionally, the contact stated that the ABS, Electronic Brake System, and Stability Control Warning lights were illuminated. The contact stated that the cruise control operated as intended for a short while but then inadvertently deactivated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the ABS module needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 63,000.
ABS lights come on with the traction control light. It also beeps each time you hit the brakes when lit. It has affected my cruise control as well. Sometimes the brake will skip when you hit a bump while braking. I have had the ABS Pump and Module replaced by a dealer on September 20, 2021. It is now doing the same thing and I had an independent repair shop inspect the truck and they found the ABS pump and module defective again. It has only been a little over a year and a half and only about 15000 miles. Dealers and the independent shop both say there are no replacement parts available at this time and it has been a big problem for Ram. I don't feel safe pulling my 41 foot fifth wheel let alone the truck itself if it malfunctions while braking. I am available for questions or inspection if needed.
Both my ABS module and HCU are out. The parts cannot even be ordered till late August 2023, my truck only as 17K miles on it. This is very much a safety issue, both of the units control the ABS system and the traction control.
Ram truck was taken to dealer December of 2022 with 7,000 miles due to ABS lights on dash. The dealer Larson Dodge ordered a new part and said they would not be able to complete it until March and to "drive it as it is". The vehicle doesn't have functioning anti lock brakes etc. Now they have told me it will likely be August due to Chrysler being the problem. This is obvious far too long and now I'm out of options.
This is the second time my ABS electronic braking module has failed in this truck. I hope I'm not one of the only owners to complain. I've read hundreds of complaints. This is May first and it's on backorder til August. It's not safe towing anything with the ABS inop.
While driving at any speed the abs and traction control lights start flashing and a chime goes constantly. also when this happens it causes the cruise control to disengage without any warning. Also leaving you without abs brakes. I am on my 3rd abs module and 2nd hydraulic control unit and needing a 3rd hydraulic control unit for this vehicle with less than 62,000 miles the first one went out around 16,000 miles and the second at 37,000 miles. This is also my second truck from this manufacturer to do the exact same thing that happened at 30,000 miles and had another one in the family that did it at 7,000 miles. As i research online I find that this a common occurrence and nothing has been done to resolve the issue other than just replacing the parts with new and wait for it to happen again. I am in need of a new hydraulic control unit and am being told that they are on some kind of hold until the earliest date of August and just to drive the truck with non-working safety equipment.
The HCU and ABS module for 2018 and 2017 model years of the ram 3500 and 2500 are a known issue that should be recalled. There's some type of issue where the ABS and the traction control lights will turn on affecting the safety of the vehicle. Many people have the issue if you do a quick search on any RAM forum. From my understanding there was a design change on the replacement part. The easiest and probably most common fix is to remove the fuse for the ABS.
ABS and Traction control lights have been on/off for 60,000kms approximately, have had it to the dealer approx 8 times for this issue, still unresolved. Traction control acts extremely odd at times and break pedal feels "soft" at times. Lights on dash come and go intermittently and so does the "soft" break pedal feeling. Warranty is now up and dealer continues to want to replace random parts @ my expense.
September-October 2022 --The Anti-Braking System module has quit working. (ABS). Requested replacement part from Dealership in October 2022. Dealership advises Mopar cancelled parts request to them. I have no anti braking working on vehicle. Dealership advises me to contact Mopar directly for help. I advised them that wasn't my job it was theirs' .
The service electronic brake light freq comes on. Dealer said it brake "module" needed changing and did. they also charged me $800 for it. Vehicle is still making the claim that the elctronic braking system still needs servicing almost imediately after repair.
