ABS System flashes on and off that it needs to be serviced, also cruis control doesn-??t work. Took it to dealer to get it diagnosed. Dealer says the HCU needs to be replaced and the ABS pump needs to be replaced and also that cause the brakes and rotors to wear out and they need to be replaced too.
ABS/Electrical Break Control fault code C002001, a known issue with the 2018 Ram 3500, occurred at 26,000 miles rendering cruise control, traction control, and trailer brake controller inoperable. Repair parts are unavailable currently and is not covered under warranty due to age of vehicle.
Ram 3500 Larime Crew Cab Deisel with 47,800 miles. We were driving home from our seasonal campsite, (about a 2 hour trip on highway) and it began to rain (about 15 minutes into the trip) it continued to rain very hard at times the whole trip home. Around 30 minutes into our trip the ABS warning light, Check Engine light, & Traction Control light came on. I pulled to the shoulder of the road and waited for a lull in the rain. I then opened the hood and inspected to see if something was shorting out electrically. I couldn't see or smell anything, so we decided to continue on our way. We exited the highway and took non-highway route home. I did not notice any issues while braking or driving that concerned me enough to have it towed. I pulled the truck into the garage (under our house) and unloaded our belongings from the weekend. I went down to the garage about 2 hours later (the key fob was upstairs) when I walked behind the truck, the cargo light and interior lights came on. This didn't make sense to me because the key fob was not anywhere near the truck. It was still raining so I decided to disconnect the batteries (2 batteries on the Cummins) rather than put the truck outside in the rain. Didn't want to take the chance of burning my house down. This was the first time this has happened (7-16-2023) I research to see if anyone else had similar issues and found a considerable number of owners with this similar complaint. The vehicle has not been taken to the dealer as of this writing. Having to pull to the side of the highway during heavy rain, put my family and others at risk. Given the number of complaints that I was able to read, I would say these issues should warrant a recall.
ABS and traction control warning lights were illuminated. The OBD reader says ABS pump motor control failure General electrical failure Code: C0020-01. The vehicle has not been repaired.. The approximate failure mileage was 45,000.

Truck has only 65, 000 miles on it, I-??m the second buyer, has never haul anything or hitch a trailer, I-??m having this electrical brake system failure ABS, this vehicle is to expensive and new to have early issues on it. ABS Motor Control- General Electric failure. I seem other similar problems reported with same year and same problems.
Repeated failure of the ABS system. Warning lights multiple times per drive. Dealer states replace HCU. Parts unavailable for over 8 months now. Dealer states known problem. Cost estimate over $1100, not covered even though known problem.
Abs/hcu faulty, brake warning light, message, and alarm will sound on and off while driving. I have tried to buy the parts and they are not available through dodge with no estimated availability. This has been going on for a year.
The ABS pump and module has failed for the 4th time. It had been repaired at the following intervals: 12 Sep 2019 - 5,374 miles; 11 Mar 2021 - 13,136 miles; 19 Aug 2022 - 20,607 miles and now 6 July 2023 at 28,944 miles, the longest it's ever made it. What's going on" It is, change the oil and replace the modules while you're at it? I never had any brake issues on any vehicle I've owned until this one. What's being done to fix this" It is unsafe, as when this failure occurs, besides having no ABS and no cruise control, I lose the trailer brakes. Having a heavy load and losing the trailer brakes should be a concern for everyone on the road. Please help.
Vehicle is presently throw an error for ABS HCU failures. There is not presently a recall but it is effecting all 2017-2018 RAM 2500-3500s. My has occurred and dealer confirmed but parts are not available for fixing. Vehicle is not safe to perform daily functions it was purchased for such as towing.
I had a new Hydraulic Control Unit (HCU) replaced with the new style that Ram expedited for me. This new unit gave me the ABS / TC Lights on my dash. Took it back to "2" different garages, they both confirmed that the pump was not being activated. Which means the 2nd HCU was a bad part! Ram / Fiat is fully aware of this problem! This needs to turn into a Class Action lawsuit! They are still putting out new RAM Truck for dealers, and they are not supporting their older Trucks! Very frustrating!!!!
I recently purchased this 2018 Ram Dually for work on our farm. After 1 trip all the ABS/traction control/4wd and cruise control wont work. It seems that this a safety issue that ram will not address. I would like to file a complaint that if I had known about these issues, I would not have purchased this truck. It is unsafe driving and with no ABS and cruise control or traction control. I depend on the 4wd in our farming business and not having this has caused me lost income because I simply could not get the job done and had to give the job away to others.
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.
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 NHTSA and other government agencies, I fear there will be several unnecessary injuries or deaths due to this known and documented common failure.
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. And the diagnostic charge was $233. 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 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.
