Anti-lock brake system (ABS) failure for second time in less than 18 months resulting in warning lights on dash, and message for service system. These include the ABS light/traction control unit light turn (warning lights, bells, and verbal system warnings) turn on whenever the truck goes over rough road, bumps, potholes, randomly, as well as starting up truck. The first incident began in July 2022 was brought into the dealer on July 18, 2022 and mileage on truck was 25,121 miles. Dealer diagnosed replaced the anti-lock brake system control unit for brake system and returned truck to me. In November/December 2023, the ABS light and traction control unit lights on dash keep coming on and system says to see dealer. These include the ABS light/traction control unit light turn (warning lights, bells, and verbal system warnings) turn on whenever the truck goes over rough road, bumps, potholes, randomly, as well as starting up truck. It also appears the cruise control will not work if the ABS system is in error. Dropped off at dealer 12/29/2023 and dealer advised that they could not repair at current time due to no parts available and earliest update may be late Jan 2024 if available. The parts that need to be replace per the dealer are the Anti-lock brake system control unit and the ABS module need replacement and no parts were available at the current time (12/29/2023) to repair the truck.

- Parkville, MO, USA

Vehicle showing Electronic Brake System as well as Antilock Brake system and traction control system not working. Pinging all the time, currently 165,000 miles on truck. Same issue was dealt with on 8/15/2020 with 39512 miles on truck. Was an out of pocket expense for $927.10 to fix this very important safety related issue. The cruise control is also affected by these messages and will not work. This is known issue around the country with these trucks and something must be done. If folks don't have money to fix or parts to get fixed we will just drive these safety hazards down the highways and jeopardize ourselves and others. What is your fix to this known problem because you all obviously are not correcting the issue for the known problem.

Hcu system failed now trucks and system is messed up, can-??t use cruise control and nervous too drive the truck for safety reasons. Dealer says it could be months for a new system

- Decatur, IL, USA

My third ABS module failed while towing (aka hydraulic control unit), resulting in a loss of ABS brakes and issues controlling the vehicle and trailer. The truck had 67,000 miles at the time of failure, and all modules have been replaced with OEM components, one of which is at my expense. There is absolutely a known problem with the HCU and Chrysler needs to issue a recall to remedy the issue and reimburse owners who have been forced to repair these vehicles out of pocket.

ABS/Traction Control warning alarm constantly going off, and affecting cruise control.

- Brighton, TN, USA

At around 74,000 miles in December of 2023, a warning to "Service Electronic Braking System" and "Service Antilock Brake System" started to show up on the screen of my 2018 Ram 2500 6.7. The truck was taken to a Ram dealership and the fix to the problem was determined to be replacement of the ABS module in addition to replacement of the HCU. Apparently, the ABS module is faulty and is causing the HCU to go bad so both need to be replaced. Replacing only the HCU will not fix the problem. The truck has not yet been repaired as a new ABS module is not available until June of 2024. When driving, the on screen errors come up frequently at all driving speeds and the error is present the majority of the time while driving.

- San Francisco, CA, USA

The ABS module is defective on my truck which controls the antilock brakes, Anti slip function, and the cruise control. Dealer ship has diagnosed problem and ordered parts but the parts have been on back order for quite sometime with no ETA from RAM when parts will be available. My dealer ship says they currently are wating on 25 parts for different vehicles with same problem.

- Paris, TX, USA

Service electronic brakes, traction control, and service trailer brakes light stays on.

- Port Allen , LA, USA

I'm just reporting the failure of my HRU as many RAM owners have experienced. The dealer ship replaced the part with the new model. When this fails it happened at highway speeds disabling the cruise control while towing a trailer. Becuase of busy traffic and under heavy weight when the truck fell on its face. I was almost rear-ended due to the sudden loss of speed. Very dangerous when towing.

- Vancouver, WA, USA

ABS intermittently turns off, brought to dealer and advised that ABS control unit and pump need replaced. Also went to service garage with same diagnosis. Dealer advised that the part in question, the ABS hydraulic control unit (HCU) was not available and would be redesigned maybe next year 2024. This problem has persisted since August 2023. It is dangerous to have the brakes compromised and the uncertainty of stopping prowess. The internet is full of identical issues concerning the 2017-2018 Heavy Duty Rams being afflicted with this issue. Chrysler should be accountable.

ABS system and traction control lights turn off and on intermittently. ABS pump and module have already been replaced and issue is still happening

- Clewiston, FL, USA

ABS and traction control light comes up randomly. Sometimes comes on then off with a chime each time rapidly for the entire time the truck is driven. Or the lights will come on and just stay on. At times the brakes become hard to stop the vehicle. Also does not allow the cruise control to work. I use this truck to haul goose neck 8 ton dump trailer and a 36' fifth wheel not knowing if the truck brakes will work is very concerning. Took it to the Ram Dealership and was told needed to replace the ABS pump at $1260. Vehicle only has 63,000 miles.

- Jamestown, IN, USA

ABS sensor light 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.
