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. Almost causing us to get rear ended. It was like slamming on the brakes, but without brake lights to warn cars behind me. I finally figured out it caused the Cruise Control to kick out. Now I am having to listen to the constant chirping of the chime. It even chimes when the truck is not moving!!! Let me ask this question.... Why is it that long ago NHTSA required Anti-Lock Brakes on all cars to improve safety" Yet, when that system has a systemic problem of failure on these trucks, it's no longer a safety related problem" Makes zero sense!!! I purchased this truck with 99K miles on it. These modules went out once approximately 10K miles later. Now I have 154K miles and they have gone out again. FCA is selling replacement modules but they are the exact same failed design. They are not only not fixing the issue, they are knowingly selling parts that have systemic and reoccurring safety failures. This is legally called blatant negligence...

Issue a recall here! Many others are reporting this identical issue and a class action suit has been filed! ABS sensor light and chime comes on at random times. My truck just reached 100,000 miles. I've performed no troubleshooting but it is extremely intermittent, either the Service the Automatic or Service the Electronic Braking System(s). Usually, a bump in the road makes it come and another turns it off. Sometimes it happens so quickly, only the message and traction control disabled light comes on, sometimes only the chime comes in. Sometimes the message stays up and the brake warning and traction control light comes on, sometimes for a few minutes, sometimes a couple of seconds. To compound the problem, there appears to be an issue in sourcing replacement parts resulting in a delay in repair. A delay in repair could result in a additional damage to the vehicle, not using the vehicle (not an option) or ultimately an accident. Also can-??t use cruise control when it-??s displaying.

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. This happened at about 30,000 miles and the truck was already out of warranty. Dodge is stating that it will cost about $2,500 dollars to fix once Hydraulic Control Units become available. Apparently there is a nation wide back order.

ABS and Traction control warning lights are on display. Cruise control and 4x4 will not engage due to this issue. Also causing malfunction while towing a trailer.

ABS / traction control as well as service ABS system. At times it comes and goes and most times now it stays on. Disables cruise control and at times even says 4 wheel drive unavailable. This seems to be a known issue with my year model Ram and I'd like to remedy this issue asap.

ABS/HCU defect. Vehicle does not stop properly without ABS and parts arnt available. Warning chime will not clear and unsafe to drive.

- Punta Gorda, FL, USA

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. Dealer states parts are on back order for years and they also state that it won-??t fix the issue long term anyways. How has this issue not resulted in a safety recall!? I-??ve read that thousands are plagued with this same exact issue.

2017 Ram 2500 ABS Pump Module was replaced before at 33,549 miles in May 2021 ABS and TCS Lights keep coming on now again at less than 49,000 miles. This is not an uncommon problem it seems, so I am adding my incident.

- Marysville, PA, USA

Intermittent MIL stating ABS and TCS service required, started has been going on since I bought the truck in January 2023 at about 50k miles (currently about 75k). Often happens when driving over any sort of uneven terrain - bumps, potholes, seams between concrete and asphalt surfaces, milled asphalt surfaces, speed bumps, debris, etc. Dealer says the ABS module needs to be replaced, and that there are none available. With some research, this appears to be a common/known issue for Ram trucks, but no recall and no effort to even manufacture the part so it can be fixed, regardless who is stuck with the bill. When this light comes on, neither 4WD nor cruise control function, which can cause safety concerns - especially while towing.

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 module unit replaced while under warranty. Vehicle again with ABS warning on/off intermittently for at least the last several months...regardless of weather, speed, road conditions, etc. Comes on and off while driving, sitting in a parking lot...pretty much as soon as I turn on the motor it starts...goes off again for several minutes/hours/days, then starts doing the blinking and dinging again for no reason. While traveling, it turns off cruise control and I have lost 4 wheel drive when I've desperately needed it. This vehicle is only used for long distance travel or during snow storms. This is a safety issue, in my opinion. Causes operational malfunction and causes driver distraction.

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

- Tusa, OK, USA

Abs light comes on and disables the cruise controls. Says abs brake failure and I have researched this and found it is a common problem. 6 speed Transmission is turning on check engine light and says gear 5 and gear 6 has improper ratio. Shifts hard into gear5 and won't downshift for passing gear.

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

- Otisfield, ME, USA

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.

- Anchorage, AK, USA

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.

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 to get it fixed. Again at about 45,000 miles it started it again. Checked with dealer said it would cost about $1400 to get corrected and they would have to wait for parts. I see a lot of others have had the same problem with that model. I feel as lot of others, this should be a recall item. Also cruise control want work when light is on. Ram is going to wait until someone has a wreck and a fatality before they do anything about this issue. Also there will be a class action suit against them and they will be plenty follow. Hope how soon Ram decides to honor this defective issue.

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.

- Wellborn, FL, USA

The ABS and Traction control lights began to flash and the alarm began to come on intermittently in 2021. I took the truck to the dealer for repairs because the ABS, Traction Control and Cruise Control were not working. The repair cost was $1,00 at my expense. The problem has recently returned and is going to need repaired at my expense again. The ABS system not working causes a safety concern with stopping the vehicle. This is a know issue with these vehicles as such I feel it should be the manufactures responsibility for repairs.
