2017 Ram 2500 Cruise Control Problems

The HCU for my truck failed and was replaced 6/25/2021. It failed again 12/2024 but before it could be replaced a recal for the HCU came out with the warning "The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning" Now the warning light keeps coming on and going off with the alarm sound as I drive. It also turns off the cruise control.

This is in regards to Recall #C4B for the ABS/HCU failure on my 2017 RAM. This recall was issued over a year ago in November of 2024, but Stellantis has yet to DO ANYTHING and can't even tell us when a remedy will be available. I have asked my local dealership and get the same answer, NOTHING!!!

HCU/ABS modules have failed for the second time in 50K miles. While using Cruise Control at highways speed (70mph) in heavy traffic the warning lines and chime came on. At the same instance the truck started slowing down dramatically.

I own a 2017 Ram the electronic breaking system light kept coming on when I had about 34000 miles on it but I had it over the 3 year period for warranty. Paid dealership about $1200.00 to get it fixed. Again at about 45,000 miles it started it again.

I have 2017 Dodge ram 2500.12/09/19 the anti lock brake system control and hcu module was replaced under warranty. Now august 2023 with 27,900 miles the same problem has occurred with the dealer recommending the ABS control module and HCU be replaced. the parts will not be avaiable until January 2024.

I have dash lights going on and off for the ABS and traction control. This is very intermitted. On two occasions I have experienced times where I had to slam on the brakes to avoid an accident.

At 30,076 miles, I began to receive 2 warning notifications in the truck’s instrument panel: “Service Electronic Braking System” and an amber ABS (Anti-lock Braking System) warning light. Both warnings include a loud audible warming when they illuminate, appear when driving the truck, but seem completely random in nature.

My ram 2500 diesel was in cruise control on a 4 lane highway with periodic stop lights when I pushed heavily on the gas pedal to accelerate while pulling a 13,000 lb trailer. When I took my foot off the gas, the engine stayed in full acceleration mode. Full braking was not slowing the vehicle much and it looked like we were going to collide in to vehicles ahead of us.

Tl* the contact owns a 2017 ram 2500. The contact stated that while her husband was driving at about 75 MPH, on cruise control and accelerated to overtake another vehicle, the throttle stuck without warning. He managed to pull the vehicle to the side and putting it in neutral, and was able to stop the vehicle.

While driving the anti-skid anti-lock failure light flashes with an audible warning. This has routinely been happening since early 2025, with the only local dealer advise is to rapidly depress the gas pedal with the key on (engine off). There’s been zero advancement to provide remedy to date.

ABS Module and or HCU finally quit working. Loss of cruise control, ESC (traction control), 4x4 and speed sensor not registering. Had now storm around the 1st of December and got stuck on road in front of house due to loss of traction control and 4x4 not engaging.

The ABS warning lights comes on intermittently saying that the ABS braking system needs to be serviced. This appears to be can common defect with the Hydraulic Control Unit and Module on all 2017 to 2018 Dodge Ram trucks. With this defect the anti skid braking system does not work and the brakes are compromised.

Service ABS comes on and off randomly. When cruising at highway speeds, it causes the random shutdown of cruise control when not expecting it. This is very dangerous.

The ABS module has failed. There aren’t any available across the entire United States in order to fix our vehicle. We have no ABS, no cruise control, no trailer brakes. We can’t get any help or answers from Ram. We have started a case with them and cannot even get a call back. The dealer cannot even order the part.

ABS AND LSC WARNING LIGHT GOES ON AND OFF. THE CRUISE CONTROL KICKS OFF. WARNING BELL DINGS OFF AND ON. CHECKED AND MULTIPLE PROBLEMS WITH THE SYSTEM

Intermittent “service ABS system” light on dash resulting in loss of ABS, cruise control, park-sense, and 4x4. No amount of troubleshooting from a reputable diesel mechanic has been able to fix this. From what I have read online this is a very common issue and the truck likely needs an HCU/ABS module

ABS/Traction control unit disabled (light on). diagnosed by dealer in October of 2023 as ABS pump and module as bad. No part available from dealer (dealer only part and ETA of 3/24). Advised to park truck until part came in 6 months. Called Dodge customer care on 5/2 to ask for update. was told no part available and no ETA in the future. I am driving an unsafe vehicle due to faulty brake system dealer can't/won't fix.

ABS and traction control light came on intermittently at first, now they are constantly on. I have lost cruise control as a result.

Abs and tc light turn on ad off intermittently regardless of what mph driven. Constant audible warning sound. Dealer states known issues with abs system hydraulic contol unit with similar vehicles.

The ABS hcu fails intermittently causing a loss of traction control, cruise control. this is the second time I will have to replace the this unit. I had to first replace it at the end of 2021 and it failed a second time in october 2023.

This has been going on since May of 2022 Every time I start my truck I get a warning that my ABS is not working and that my electronic braking needs to be serviced.

ABS warning lights going crazy kicks cruise control off and traction control and 4x4 stop working Constantly dinging and flashing don’t know if brakes will work or not

This started in May 2023, warning lights "Service Electronic Braking System", "Service Anti-Lock Brakes". It is an intermittent issue, cannot duplicate. Appears at random, with Cruise control on,, if the issue message appears the cruise control disables.

The anti-lock and traction control light and service light came on shortly after purchase, this happened while towing a 10,000lb camper in the N. GA mountains. this was a challenging situation with that much weight pushing the truck and the brakes weren't working properly.

This is an ongoing problem and it appears to be affecting other owners of this vehicle as well. The code is C0020-001. The ABS/Traction control light comes on - a message to service the Anti-Lock braking system comes on - and the cruise control does not work.

The ABS and traction control light are coming on and off and malfunctioning with a dinging bell alert. With a message that says service antilock brakes soon. On wet roads the steering seems off and brakes lock up.

ABS and Traction Control warnings cycling on and off randomly. Warnings are off only for short periods and are on most of the time. Cruise control is not working when the warnings are on which causes a sudden unexpected drop in speed on the highway when a warning cycle occurs.

While driving down the road my vehicles ABS and Traction control light go on and off, most of the time the lights are stuck on. Causing the vehicle to not have ABS and traction control during the rain and snow months of the year an further more the cruise control does not work.

Cruise control quit working when towing my trailer with tractor loaded. Service antilock brake system and service electronic brake system messages and lights on dash showed. Would occur intermittently, then became more steady.

The ABS control module and the HCU has Failed twice on this truck resulting in loss of traction control, ABS and cruise control. The unit was replaced around 42,000 miles and then failed again at roughly 60,000 miles. Ram will not replace under warranty. the failure causes the abs and traction control light on the dash to come on and off constantly. it also shuts down cruise control. I believe it also causes excessive ware on the rear tires due to the traction control system not working properly. This is a major problem and judging by online repair forums there are many other people experiencing the same issues

June 26th 2019 my truck felt like it shifted into 4WD on its own, later that day I lost ABS, traction control and cruise control. It went to the dealership where it took 3 days to diagnose. Was informed that ABS pump and ABS control module need to be replaced and the part is not currently available.

On at 3 separate occasions, I have had the accelerator get stuck on what I believe is full throttle. Initially I thought it might be my floor mat, however it happened yesterday in a parking lot. So there was no reason for the peddle to get involved with the floor mat.

With cruise set at 75 MPH, speed would decrease to around 71mph, then unexpectedly and rapidly increase to 75. This happened repeatedly and I stopped using it for about 3 weeks. I tried it on return trip and it worked fine.
