In 2020 my abs traction control warning light came on took truck to dealership. They replaced ABS motor. 1 1/2 year later the warning lights started to flash on which progressed into always on by April 2023. I had the truck at dealership for another recall and they tested and system. Dealership stated they would repair under warranty. I have been waiting 10 months for repair and they state they cannot order the part yet 3/2/2024 since they can only order so many per month and there is a long list in front of me. I have noticed a loss of braking power. And I am not able to use cruise control either

There is an ongoing issue on the 2018 model RAM 3500 trucks, with their braking system. This is the 4th time that my ABS brakes have failed. There should have been a recall a long time ago. This last time the ABS failed, I brought the truck to the Garber Dealership in Greencove Springs, FL 31 July 2024. They didn't have the part and stated that it wouldn't be available until Feb 2024. They received the part (Hydraulic Control Unit (HCU)) and I brought my truck in to have the repair conducted 13 Feb 2024. The dealership called me later that day and told me that they ran into an issue that the HCU was not communicating with the ABS Module and the technician was unable to bleed the brakes. She said that they needed to order the ABS Module. After not hearing any status following that, I called back the late afternoon of 15 Feb 2024 and was told that the part wouldn't be available until June. Prior to bringing in the truck, I had brakes, just not ABS which also cancels out cruise control and trailer brakes. Now it has NO brakes and it sits on their lot until June. I bought the truck new from this dealership and the following is the history of every time the HCU and ABS Module was replaced: 1st time, 12 Sep 2029, 5,374 miles; 2nd time, 11 Mar 2021, 13,136 miles; 3rd time, 19 Aug 2022, 20,607 miles; 4th and current time, 31 July 2023, 29,769 miles. If this is the not the correct agency to help with this issue, please let me know who to contact. Thank You.

I purchased vehicle new June 2018. On [XXX]. I had a Fault code of ABS brakes system and took to Mountain Valley motors Blue Ridge, Georgia for repair and replacement of hydraulic control unit. At that time the mileage 22,140. [XXX] had the same failure again and the fault code reading service ABS brake system. Took the truck to Jim Brown Dade city Florida for Repair with the fault, code reading, and replaced again the same hydraulic control unit for the brake system. Second replacement of same part. Mileage 31,482. [XXX] had the same reoccurring fault code service antilock brake system when red same problem replace hydraulic control unit for the ABS brake system. Had that repair done again and mileage 37,290. At that time they had stated a new hydraulic control part was available with part number ending in AB. Part installed 68143491AB. After returning home, approximately 120 miles later, I am having fault flash on dash screen again, saying to service ABS brake system and then disappears. I took the truck to the dealership Jim Brown. They connected their computer and said there was no codes to be read. I again had the same message flash up every day. The first time I started the vehicle and would disappear. I took the vehicle back to Jim Brown dealership. They read the code again with an additional approximate 140 miles, and no code appeared on the computer. I was told, then to just let the part fail. Is that putting me and my family in jeopardy possibly fatally by a manufacturer refusing to repair vehicle which has been a known issue before 2017 based on ram TSB advisories that I have in my possession, addressing the issue of the faulty ABS braking system. I have exhausted, all avenues with ram cares and ram dealership to. Please advise where I can go with this issue.

I was driving my family and the ABS light randomly popped on during a rain event and the vehicle had difficulty keeping traction. The vehicle was scanned and the code C002-01 was displayed meaning that the ABS module had issues. The vehicle has not been inspected, today, February 13th 2024 I reached out to Tacoma Dodge where the vehicle has previously been serviced to determine if this was a known issue since after a quick google it sounds like I am not the only one experiencing the issue. More digging pulled up a publication from Ram #S2005000004 which talks about the issue and parts being restricted. I also found an additional source that mentioned a class action lawsuit. I figured it was in my best interest and other owners who have experienced this issue to notify the NHTSA to assist with the investigation.

The truck will continually flash an ABS and Electronic Break System (EBS) service light with alert ding. I replaced the ABS pump and it went away for a while and now it is back with no parts to be ordered to fix. This has become a known problem on all 2017-2018 Ram 2500 and 3500 trucks. This issue is ongoing and there is no rhyme or reason as to why it is happening. The only option is to replace the ABS hydraulic pump.

The ABS light and Traction control light keeps coming on and off very frequently. I am being told it is the Hydraulic control unit, as well as the abs module. This seems to be a huge safety issue that many people are running into.
