I TRY NOT TO DRIVE TRUCK AT ALL EVEN DEALER SAYS TO DRIVE IT WITH NO ABS OR TRACTION CONTROL.

While driving at any speed the abs and traction control lights start flashing and a chime goes constantly. also when this happens it causes the cruise control to disengage without any warning. Also leaving you without abs brakes. I am on my 3rd abs module and 2nd hydraulic control unit and needing a 3rd hydraulic control unit for this vehicle with less than 62,000 miles the first one went out around 16,000 miles and the second at 37,000 miles. This is also my second truck from this manufacturer to do the exact same thing that happened at 30,000 miles and had another one in the family that did it at 7,000 miles. As i research online I find that this a common occurrence and nothing has been done to resolve the issue other than just replacing the parts with new and wait for it to happen again. I am in need of a new hydraulic control unit and am being told that they are on some kind of hold until the earliest date of August and just to drive the truck with non-working safety equipment.

ABS and traction control lights come on intermittently and a chime sound occurs. When this happens cruise control stops working. Getting a “Service Electronic Braking System” message and “Service Antilock Brake System” message. Had to wait three weeks to get an appointment for dealer to troubleshoot. Dealer said it has code C0020-01 logged. Dealer says the Hydraulic Control Unit (HCU) has an internal failure that is shorting out the ABS pump control. Dealer stated that part will not be available until February or March of 2024 if not later for repairs. Dealer verbally said to either park the vehicle until part is available or drive it knowing that the ABS braking system may not work properly in case of emergency stop. Dealer said there is no recall for this problem but they are aware of many vehicles with it. I feel there needs to be an immediate recall issued for this problem as it is endangering the public.

Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.

My 2018 3500 Dully with 34,000 miles started having an issue with the ABS, Traction Control and Eletronic Brack control systems. While driving the truck on a trip, the Traction Control, and ABS lights started coming on intermittently and the check Eletronic Brack control came on at the same time and it too flashed intermittently. Also, while this is happening, the cruise control does not work. Took the truck to the dealer, parts are not available until February of 2024. Five months from now. They recommend two parts be replaced, Anti-lock brake system, part number 68347098AB and Control Anti-Lock Brake System Part 68143491AB. I'm being told it will cost around $2,000 for the repairs. The 5-year 100,000 drive train is within the warranty period; however, this is not covered by RAM. For such an expensive truck, I find it disturbing that in the event of such failure It was advised to take the truck into the dealer as soon as possible because the truck with an ABS issue is not drivable and the dealer says its ok to drive it even though all the systems lights are flashing intermittently.

The warning chirp occurred and the ABS and ESC lights came on the first two times. The incident happened so quickly I could not clearly determine which warning lights illuminated. On April 18 with just over 39,000 miles on the vehicle the chirping alarm and the ABS and ESC light illuminated. In addition two warnings appeared in the dash: "Service Antilock Brake System" and "Service Electronic Braking System." The warnings happened multiple times per minute in some cases. Other times the vehicle would go for many miles without the warning. Every time the warning chirp was heard the cruise control would disengage. I did not notice any problems with the brakes of the truck. In researching the issue I learned that many people are having this problem. I contacted Ram and they directed me to a dealer who diagnosed the C0020-01 fault code and that the hydraulic control unit (HCU) for the ABS system was defective. According the the TSB Ram has put out about the issue the ABS module could also be bad, but the first part of the repair it to replace the HCU and if the problem persists to then replace the ABS module. Ram apparently has an inconsistent level of support for owners experiencing this malfunction with some getting the repair done out of warranty, while others have to pay for the repair. Because it is brake related it seems this should be an item replaced as a safety issue, no matter what the mileage on the vehicle.

The abs system has failed on my truck and many more possibly by a dealer defect and no recall as of now. When the abs warning light comes on it also puts up a warning light for the electronic braking system and you aren’t allowed after that to set the cruise. Anytime you hit a bump or turn the wheels or just randomly at any given time the lights come up on the dash and it chimes which will drive anyone nuts. With the electronic braking system not functioning properly could potentially lock the brakes up on the truck in my opinion knowing how it functions. Which in my opinion is a safety hazard. Also I might add that taking my vehicle to my local dealership is a complete waste of time as the diesel mechanic up there is terrible at his job. He has misdiagnosed two of my trucks and I believe he had something to do with a transmission going out in one. He “fixed” it then 3000 miles later the transmission completely destroyed itself which made me have to trade the truck in. Also the traction control system does not function when the abs light is on. In doing research I have found many many people with this same problem.
