The warning light comes on and then the traction control goes off and the cruise control will disengage all at once. There is also no trailer brake assist. This has been verified by a dealer in Columbus, GA. It is constantly going off and on. The warning light and the warning bell are a constant distraction to the driver. The truck was bought and within 50K miles it started. No warning.

In May of 2023 while towing my boat I got warning bells and flashing lights, alerting me of the failure of the ABS brake system. In a few miles the warning went away. Then came back on, about 12 times in 20 miles. I also lost my cruise control and traction control. I took to the dealer, about 10 times before they were able to have the episode happen. It was intermittent at first but VERY annoying and Unsafe. The ABS system is almost always in failure mode and has been since about August. They order the parts in June, I'm still waiting. I use the truck to tow a car, a 34 foot 5th wheel and numerous other heavy loads. ABS is very important as is the cruise on my long trips. I'm still waiting, no help at all from Chrysler corporation!! Almost everyone I've talked to with a 3500 and larger truck, has had it fail. I'm tired of paying for a vehicle that is unsafe to drive. I want Chrysler to offer to buy it back, offer a good trade or repair. Please make them fix what they sell!!

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

My ABS and Traction control lights will come on and off, making my cruise control stop working without warning. sometimes it stays on and sometimes it goes off. it is completely random. I'm seeing lots of reviews saying this is happening to others and its the HCU module and the abs control. please help get this fixed

ABS and traction control lights intermittent flashing. Service ABS warning flashes and chiming occur. Very distracting and makes me unsure of failure of system.Codes and stored messages clear and repeat. Cannot go to dealer every day to have codes read that don-??t exist. Parts not available at dealer. How is this fixed?

ABS mogel is defective and needs to be replaced. ABS light and chimes come on constantly. Affecting braking and lose of cruise control ability. This is a know fact that it is a defective part on ram trucks.

- Hershey, PA, USA

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.

The antilock brake system warning light because it's faulty The brake system affects the speed control And they don't have reliable parts to repair

- Melborne, FL, USA

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

Dealing with intermittent service brake system messages for over a year now. Light is constant now which means my ABS / anti skid/ and cruise control no longer function. Believe this is the ongoing HCU / ABS module known issue. Frustrating going into the winter months with such a heavy vehicle and loss of safety feature with no fix from Ram.

- Portland, TN, USA

Traction control and abs lights have been coming on randomly while driving over the past several years. Seems worse and more frequent in cold temperatures. Scanner reads code C0020. Cruise control suddenly shuts off when this happens causing a safety hazard especially to those traveling behind. Dash lights and constant chimes are very distracting while driving. No abs makes winter driving more dangerous as well. Seems to be a common problem with this vehicle. There should be a recall issued to fix this.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and was replaced on my vehicle. I had the vehicle back to the dealer numerous times before they replaced this item. 14000 miles later the same problems are happening again. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. The warning lamps and messages will flicker on and off repeatedly and randomly while driving.

- Chesapeake, VA, USA

ABS and traction control warning lights intermittently come on. Has been repaired twice by local dealership by replacing the two computer modules/pumps responsible for ABS system. Cruise control disengages when this happens. When this happens at highway speeds while pulling a heavy trailer in traffic it's a very dangerous situation and needs to be corrected by manufacturer.

I purchased my Ram 3500 new, in 2018, at Nucar auto dealership in Tilton, New Hampshire. When I reached approximately 24,000 miles, my "Check ABS" and "Check Traction Control" lights activated on my dashboard and the message console. I was using cruise control at the time, which immediately deactivated. This could have caused an accident if I had been slower to react. The warning/failure was intermittent at first, but over the next few days became almost constant. The lights/warning would flash, the warning bell would ring, and then shut off for a minute. Over, and over, and over. I brought the truck to the dealer and they ran a diagnostic. They diagnosed the following: C0020-01 - ABS Pump Motor Control-General Electrical failure INTERNAL HCU OR ABS MODULE FAULT. WILL NEED TO REPLACE HCU AND RETEST The truck only had 24k miles on it, but since it was past the 3-year warranty period, they quoted a cost of almost $1,000 to do the repair, not counting the $155 they charged to run the diag. They also stated that the parts were on backorder, and wouldn't be available for some time. Since then, I have driven the truck as little as possible since it is a safety issue. Based on information in online forums, I know that this is a problem in thousands of 2017-2018 Ram 2500&3500 trucks. My next step is to join one of the several existing class-action lawsuits, create a new class-action suit for New Hampshire, or file an individual suit. Will Ram issue a recall for this?

My 2018 Dodge Ram with 7175 miles on it has a continuous service anti lock brake and service electric brake light go on and off.Cruise control inoperable as it shuts off when the warning lights go on and off.Dealer did a $160 diagnostic on the system that I had to pay for only to tell me the hydraulic control unit needs to be replaced at a total cost of $825 that I am responsible for.Additionally, the part is -??controlled-?? by the manufacturer and they are allotted one unit per week.No time frame when the vehicle will be repaired.This is a safety issue especially when the constant -??chime -?? goes off which is very distracting.I haul a camping trailer with this Ram 3500 duelly four door diesel four wheel drive and the braking is questionable.

The Hydraulic control unit has failed. It has been taken to a mechanic and diagnosed. The electronic part has been replaced per my warranty info and mechanic recommendation and it is still failed, meaning the main HCU is the issue. The cruise control will shut off automatically and the ABS and traction control do not work while in fault. While towing a trailer up an on ramp, the HCU went into fault causing the traction control to fail and the pick up lost traction and started sliding sideways...Luckily I was able to get it under control without crashing. This was all due to the HCU intermittent failure, causing the traction control to stop working. While this is faulted, the ABS also does not work.
