Service antilock braking system

- Ruskin, FL, USA

Abs brake service light is on and off while driving or when hitting bumps or parked and applying the brakes.it intermediate on then off. This is a low miles vehicle and is used basically to tow from time to time.After doing my research this is a problem with the abs system malfunctioning. Haven reported to a dealer yet but research say these parts are in back order for long waiting periods.

Continued intermittent ABS light and "service ABS System" message with annoying / distracting chime, Loss of ABS and traction control, I have had several instances when the braking of the truck has been affected and could have easily caused an accident. Between the braking issues and the constant distraction of the vehicle chiming and alerting of a system issue, this needs to be looked into. the number of complaints does not show the actual number of people that are having the same issues. I have talked with several other owners that have had the same issue and the dealership repaired them but not reporting anything.

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. Service electronic breaking system Service antilock break system When this alarm happens you lose traction control, ABS breaks, and trailer breaks if towing a trailer this is a huge safety factor.

The ABS and traction control lights come on intermittently on the dash and the message to check the brake system comes on alot. The ABS system doesn't work when the lights are on and they come on alot. This I believe is a safety issue since it came with an ABS system to keep from locking up the brakes when having to brake hard to avoid a collision.

While driving, my "service electronic brake system" and "service antilock brake system" would come on and go off repeatedly. Other times, nothing would happen. Then it would come back on and stay on. Next time, nothing would come on. Shop states that it was antilock brake pump. He said that these are known to be bad but the part is backordered with no timeline available.

When I was returning from a trip across town my "service electronic brake system " came on with a chime and then went out. This was followed by check "service brake system" which also went out. They stayed off for a few days and then did it again. This condition got more and more frequent. I took it to the dealer and was told that it needed a ABS control module. I felt this was very early for an ABS failure with only 30762 miles on the unit. I now have 48845 miles and the ABS light is coming on and off ( with it's chime ) even when I sit at a traffic light not moving and going down the road it is almost constant. I have read in the Ram forums that this is a common issue. I believe this to be a safety issue. Why have ABS if it's not going to work.

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.

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 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

The HCU failed twice under warranty illuminating the ABS and TRAC lights disabling ABS functions (obviously fixed by a dealership). This is a safety hazard trying to stop a RAM 3500 without ABS, this in poor weather is beyond UNSAFE. Now, it has failed again not under warranty, same issue, same part. That is four units that have failed in my truck with only 27,000 miles in five years. The brushes in the electric motor start to fail so the ABS/TRAC light will flicker when hitting bumps, or in cold weather. The finally, they stay illuminated disabling crucial brake components and safety systems. I can have my vehicle looked at if necessary, I plan on replacing the HCU myself when the part arrives in a week (I work for a dealership).

Abs light/ warning goes off and on continuously. Brought truck in to repair and was told that they aren-??t making the parts to repair this known issue on many vehicles. Was told parts available In February which has now been changed to April. This is not acceptable. Along with being very annoying with warning light flashing off and on. It-??s also unsafe. As the ABS and traction control are affected by this.
