2018 RAM 3500 Complaints

ABS light goes on and off. I took it to a dealer and was told it was a C0020-01 ABS pump motor control electrical failure. There is no fix at this time as Ram is looking into the problem and will not supply any fixes until further investigation. The light and chime goes off all the time and it also cancels my cruise and anti slip. There needs to be a repair for this.

Starting in May 2023 mu truck has experience intermittent ABS System errors and Service Electronic Braking System service messages. At many times the errors will repeatedly clear and reoccur, sometimes as frequently as once every second or two. Sometimes the error messages come on and remain so for long periods. When in an error state, the ABS system is not functional and the vehicle will not allow activation of cruise control. My RAM dealer has advised that, despite the fact that this issue has been ongoing with RAM trucks for over years, there are no parts available and ETA for a redesigned part has just been delayed 6 months to June 2024. This is a faulty safety system.

2018 Ram 3500 has a code C0020-01 anti lock braking pump motor failure. Seems to be a common problem that Ram trucks has not recalled. this is a blatant safety issue that they seem to be ignoring. Parts to repair this issue is hit or miss from what I understand. Please step in and hold ram accountable.

Abs electronic brake light issue,brakes spongy and feels like it’s lost braking power.

From what I understand these Ram Pickups have numerous problems with the ABS module and HCU unit going out and our truck has had the same problem we had to replace the HCU unit at only 10876 miles on November 4. 2020 and now we have had the ABS warning lights coming on and took to dealer on 10/11/23 with only 22287 miles and they say we need a ABS module, we are told this part 68347098AB is on back order and as of January we still have not received it and now dealer is telling us they came out with new part number. For ram not to be able to provide parts to fix their defective braking system parts is a safety issue and Ram should make this an urgent recall issue and pay for the replacement. You cannot find the part anywhere and Ram Truck owners are having to drive with dinging warning lights and unsafe braking issues.

The contact owns a 2018 Ram 3500. The contact stated while driving 60 MPH, the vehicle unintendedly steered to the right. There was no warning light illuminated. The contacted turned the steering wheel between the 10 and 11 0’clock positions to keep the vehicle aligned. The contact stated that the failure persisted. The vehicle was taken to the dealer and was then towed to a local mechanic however, the vehicle was not repaired. The vehicle was not included in NHTSA Campaign Number: 19V021000 (Steering). The manufacturer was made aware of the failure. The approximate failure mileage was 102,000.

While driving the ABS and traction control warning flashes and dings with every small bump that is hit. Confirmed HCU unit by stans garage in Duncanville tx

The Anti-Lock Brake & Electronic Braking System error caused the internal Trailer Brake system to shut off trailer brakes just like it shuts off the cruise control when warnings come up on the dashboard. The incident happened Aug 28, 2023 while following my son and my wife in a vehicle ahead of me. I had to change lanes to try to avoid something that suddenly came across in front of my vehicle. I applied the brakes and then the trailer acted like it didn't have any brakes fell over & was totaled. If this was in traffic someone could have been killed. The "Check Anti-Lock Brake System" & "Check Electronic Brake System" warnings started coming up intermittently as I drove my RAM 3500 Diesel truck starting sometime around July 2023. I drove to the local RAM dealer and told them about the problem. They acted like they had never heard of this problem and proceeded to check the error code and then stated they had never heard of this error before. They said they would check with RAM engineering on what needed to be done. They then said there were other similar RAM trucks with the same issue & that the parts were on back order. I finally got an appointment for the dealer to check my truck after sending an email to the Service Supervisor. After they checked my truck on August 16, 2023 they said that my truck needed a new Anti-Lock Brake Control Module. I had seen that many others on the internet blogs had stated that both the Anti-Lock Brake Control Module and the Hydraulic Control Module (HCM) needed to be replaced. I was then told by the service person that the Anti-Lock Brake Control Module would not be available for months (until sometime in December) and the Hydraulic Control Module (HCU) had no date of availability. They also checked with the RAM technicians at the dealership about safety driving the truck and towing a trailer until the part came in. They told me that only the Anti-Lock Brakes may not work so it would be safe to continue to drive it and tow a trailer.

Service Electronic Brake System Warning. This warning started coming on sporadically. When the warning appears in my dash, I will lose abs function, traction control, and cruise control. This appears to be a common problem with this year Ram truck. The fix is an abs module, and or, a hcu module.

In September 2023 I started getting a warning to service the ABS system. The warning and associated annoying tone would appear and than disappear at different times. I spoke with the service manager from Lithia Dodge where I purchased the truck. He told me that he was unable to service my truck because the ABS parts are not available. I was told that like a great number of Ram truck owners, I had to "hurry up and wait for a solution." This is unacceptable. To make matters worse, I am moving out of the country in February. I had a buyer for my truck and now it is un-sellable due to this ABS issue. I hope that a re-call will be issued soon so those of us with this common issue can get some relief. Thank you
