ABS and traction control light and electronic braking systems warning lights are on. The parts are not being produced by the manufacturer per them. This is a safety concern as these trucks pull heavy loads. This is a systemic issue with 2018-2019 RAM 2500 and 3500. The issue has been inspected by dealer and repair shop. ? Manufacturer is unresponsive to owners and dealers. There are currently 2 class action lawsuits on this matter.

- Forest Hill, MD, USA
ABS and traction control lights come on intermittently. Cruise control won-??t work when this happens. Problem seems to be a wiring issue and mainly happens during wet conditions and then stops after engine compartment warms up. I-??m guessing ABS brake-??s won-??t function when light is on.

ABS failure, consistant "service electronic ABS system" warning flashing, very random, oftem times going off for hours during long rod trips. On several occasions, the ABS system seemed to malfunction without any warning and then the warnings sound. Very similair to the preported issues with the ABS module/hcu issues.

- Ebensburg, PA, USA
Warning light stating service electronic brake system and ABS light comes on. Being in northern Iowa during winter could cause loss of control during breaking. Took vehicle to dealer that determined the ABS module was malfunctioning. Left vehicle with dealer from December 2023 to April 2024 because dealer stated they were waiting on the part. Then let me know they could not get the part. Mopar currently states the part is unavailable. I am left with a vehicle that could malfunction at anytime and no way to fix it.

The ABS module and HCU have failed for the second time. The first time they were replaced under warranty but now the truck is just outside of warranty and not covered and this is a 1600 dollar repair on a truck with 60k miles. The first time was approximately 30k miles. My safety is at risk when brake parts are malfunctioning and the problem has been confirmed by the dealership, and it's a very common issue without recall. Constant dinging happens while driving from alarms on the display stating to service abs and esc systems.
- Liberty, SC, USA
We have been waiting on an improved HCU for the ABS system for approximately 18 months now to no avail. The ABS system is constantly failing and throwing codes related to the HCU and ABS module which shuts down the ABS system as well as cruise control and the dash lights up like a Christmas tree more times than I can count. My local dealership has no information on when parts will be available to fix this issue. The HCU has already been replaced once with the old stock unit and it has failed. This is unacceptable and a major safety concern since we are frequently hauling horses. Any information related to a fix would be greatly appreciated since RAM doesn-??t seem to care at all.
- Sanford, NC, USA
ABS light keeps going on and off. Had it repaired/replaced once under warranty, no longer under warranty. Nearly skid off the road on a rainy day when someone braked hard in front of me. This ABS issue is very dangerous. In my opinion, I shouldn't have to keep paying to repair this since it constantly fails.

In March I started experiencing an intermittent ABS warning light. When this light is active the truck is without anti-lock braking and traction control (as well as cruise control), which are critical safety features. This is the second time that I have had this problem on this truck with the same module. In both cases I had the dealership make the needed repairs. The first instance was repaired under warranty on 11/06/2020 at 24,433 miles. The most recent instance was repaired on 3/27/2024 at 44,181 miles and at a cost of $798.15. These two failures indicate a service life of less than 25,000 miles for a critical piece of safety equipment. The attached dealership repair invoices show that it was the exact same part that was replaced. At the time of the most recent issue, I contacted Ram Customer Care by phone and after several calls back and forth they declined to provide warranty cost assistance. However, they indicated that they had contacted the dealership, but incorrectly reported back to me the cause of the fault. I pointed out that they were making a determination on apparently incorrect information. When they declined the second time I requested that they put that in an email, which is attached. Given that there has already been a recall on later model years for this exact problem, and that there appears to be a substantial number of similar claims from 2017-2018 model years owners, I would like to add my experience (and expense) to whatever other complaints that you have received and encourage a recall for this issue on these model year Rams in order to save lives that could result from a system failure during a critical incident.
