The hydraulic control module and the ABS module are not working properly. This is a known defect on these trucks. When the lights are on, the ABS will not engage. I have had the truck at the dealer, and they said since there is no recall, they can do nothing. This problem was addressed in a recall for 2020 and newer trucks but not for 2018 trucks. I know of two class action lawsuits, one in Texas and one in California.

For the last few months, my ABS/Traction control lights on the dash board have been flashing on and off over bumps and even flat road driving. Over the last few weeks, the ABS/Traction control lights have been staying on constantly. I am nervous to tow a heavy load with these lights illuminated since this is dealing with the brake system. After some research, I have discovered this is a huge issue with the RAM 2500 and should be fixed by the manufacturer

Starting about a month ago, I started receiving a warning about servicing my electric brake system. Was very intermittent. Spoke to the dealership and they said if it wasn-??t happening right then, they couldn-??t read the codes. If the light went out, I could wait to bring it. Went on a trip, and it started happening more frequently, but still intermittently. I tow a 7-ton fifth wheel, which made me feel very unsafe. Sometimes happens moments apart, and sometimes hours apart, and it always knocks out the cruise control. Looking online, I found that this is a very common occurrence, and that I should report it. I did not have an accident, and tried to do my best to drive safely so I could get home.

ABS / Traction control error intermittent alert.

the ABS light will come on while I am driving along with traction control turning off with a ding. While the warning comes on, the cruise control will turn off. It will turn on and off several time during a drive and will ding when it comes on. Very distracting and annoying and distracting. the dealer will charge me to look at it to find a reason. Truck has 37,000

ABS/TRACTION CONTROL LIGHTS and alarm started in January 2022 the vehicle only had 21,460 miles on it so I took my 2018 Ram to dealership to get looked at and they diagnosed the faulty part as ABS HCU/MODULE. The vehicle was under warranty so they fixed it for free. October 01 2024 the same thing happened vehicle with 38,000 miles all the lights started flashing and alarming while I was towing my camper I've heard that when this happens it disables cruise control and the trailer braking system. THATS VERY DANGOUS WHEN PULLING A 8,000 POUND CAMPER!! Now I've heard that the part is on back order and 'm lost on what to do.

The ABS system lights and dinging keep going off. Started months ago. Stopped for a while then does it randomly sometimes a lot, sometimes once in a while. Theirs is no rhyme or reason why or when it dies it. Stopped at dealer and they said this year was having problems and they have been back ordered with parts and have no idea when they will be in.

On 10-01-2024, I took my 2018 RAM Truck for service at the Warrensburg, Missouri Dealership. The reason was due to service lights coming on in the truck to tell me the ABS and Electronic Braking System had issues. The dealership service department replaced a faulty HCU and the "Control Anti-Lock Brake System". My truck had 69850 mileage when the service lights came on. This is the second time, the HCU has been replaced due to the same issue in 04-21-2021, when the same truck had 30945 miles. The dealership explained this is due to RAM contracting the HCU part from a manufacture that proved to be bad. They have now changed manufacturer and the new part is being installed. A quick search through the internet shows this is an issue in RAM trucks over the years with two lawsuit in two different states. The loss of the braking systems, especially when hauling trailers and campers can cause serious braking issues. Why has there not been a recall issued on this HCU? Not only unsafe, but not being warrantied by RAM, my repair bill for their error in manufacturer, cost me almost $800. Please investigate before a serious accident occurs over many years of these RAM trucks using a faulty HCU.

Currently I own a 2018 RAM 2500. I am the original owner and do regular Maintenace on my truck. The ABS & Traction control light flashes on and off consistently (Very annoying while driving). I have brought my truck to the mechanic and told me I have to wait on a part that is on "National Back Order".... No dealership has the part, and no website has the part. Only place to be found is on eBay used with no warranty they work, or proof they have been refurbished. From what I have been told it is the EBCM. I did research to try and find the part. No where has it, and nowhere to be found. This is where I found out it is a frequent problem over a lot of people. I see RAM has a recall for the same issue with 2019 & newer, but no recalls on the 2013-?"2018-year model trucks. This truck is my everyday driver, and I need it fixed....

Anti-lock Braking System module failure due to poor/defective manufacturing and/or parts. This is a known issue with 2018 RAM 2500/3500 trucks. Safety is at risk due to failure of the ABS module which affects stopping performance. The RAM delear has diagnosed the issue as intermittent. The warning lights go on/off constantly while driving causing a distraction as well. This part should be recalled.

While under warranty (no paperwork available for exact date), the ABS and Traction Control warning light would intermittently turn on and then go off. It was taken to the dealership and repaired under warranty. I now have 40,000 miles on the truck and am again having the same issue.
