My 2017 Ram 2500 Cummins pick-up truck started displaying symptoms of a bad HCU module several months ago, "Service Electronic Braking System" warning message, ABS dash light indicating loss of ABS, and Traction Control Light indicating loss of traction control, as well as kicking the vehicle out of Cruise Control when this set of condition lights are, albeit intermittently illuminated. There are times where these condition light persist for long periods of time from several hours to several days, and then times when these condition lights aren't present and will only intermittently come on and then times when these lights blink/ding on and off constantly for several minutes until it comes to rest in an always on state or an intermittent state. …
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. After getting a code reader, I found out the HCU has been listed as a service problem. You try to find the part and there is a hold on releasing the part because the manufacture is having problems with the updated part, and they don't even offer the original part because of the defect on the original part, (part # 68143491AA) The replacement part is (68143491AB). Thankfully I grew up driving vehicles without modern ABS , If my wife would have been driving, or an inexperienced driver, this could have ended in a very, very bad situation. Why isn't there a safety recall on this vehicle? …
Problem #1- I had to replace the ABS module and HCU on this truck at about 10k miles. (this was completed under warranty). Then at 50k miles truck was diagnosed with the same problem. I had to pay out of pocket for this repair. I ordered these parts from the dealer in November 2021, and they did not get me in until August 19, 2023. I had to pay ($1152.33). This is very dangerous when it has this error it causes the service sabitrac and service abs pop up on the display nonstop with no way to clear it. It also chimes every time. it is very distracting. while these service lights are on, I had no cruise control or traction control. Problem # 2 Transmission over drive failed. I had to replace transmission and transfer case. This makes for an unsafe vehicle that could leave me stranded on the side of the road. this repair cost me ($7,500). Failed at 67,675 miles. …
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!!! The parts must be available, because the dealership told me that I could purchase the part from them and pay them to install it. But, I would have to then wait to get reimbursed from Stellantis once the recall is "remedied". Two problems with this; 1) I don't have the $1500+ to spend on this, and 2) I don't trust them to ever pay me back! But, this does tell me that they have the parts. Plus, they have no trouble making and selling new vehicles with parts that don't have this safety failure. …
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. …
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. Either or both notifications illuminate and the warning lights stay on for as little as a few seconds to as long as a minute. The frequency of the audible and visual warning lights is also random. On some driving trips, they may appear up to 6-7 times each minute. On other trips they may occur 2-3 times over several miles/minutes. driving/stopping on wet pavement could be problematic because the ABS, Cruise control, and built-in trailer brake controller ALL stop working when the warning lights come on. …
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. …
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. Dealer had said 4x4 was working when they informed me the ABS module needed replacement. It currently at a private diesel repair shop and they confirmed the ABS module needs replacement. Currently awaiting a ship and repair service to see if the module will work and fix the loss of above. There were two warning lamps on the dash lit up. The ABS and Traction Control light. I am hoping that all I need is the module repaired and that I don't need the HCU replaced. This is super frustrating because there is a recall on the parts but the dealer and the company are in no hurry to find a remedy for the issue.
