ABS light came on at 13,000 miles and was repaired under warranty. At 27,000 miles (2.5 years later), ABS has failed again, code C-020, but vehicle is out of warranty. Contacted FCA and was told "sorry, its out of warranty, pay for it yourself and keep your receipts, just in case it goes to recall". This is a know safety issue as cruise control and traction control are also tied to the ABS. Driver distraction should also be mentioned due to the entirely random but frequent chimes going off due to ABS failure. When the truck was "repaired" the first time, the bad parts were replaced with identical parts, i.e. not a redesigned, more dependable part, but the same poor design as stock.

This issue is related to 2017 Ram 3500 truck with 6.7L Turbo Diesel motor: The warning lights for the ABS and the Cruise Control intermittently activate and there is an audible alarm ding noise along with them. This ABS warning light going off intermittently indicates that if a situation arises that requires the ABS system, it may not activate as designed. Which in turn could contribute to loss of control or accident with the vehicle. This problem has been confirmed by Villa Rica Auto in Villa Rica, GA. This vehicle has been inspected by Villa Rica Auto. They advised that the problem is with a defective HCU and that part is on back order with no ETA available. This problem first appeared a few days after buying the truck from Gravity Autos Atlanta. This truck was not involved in a crash.

ABS brake warning lights are on and cruise control will not work. I was told by the dealer the module had to be replaced. This truck only has 34691 miles on it now and this problem started over a year ago. Dealer said this part was not available because of supply chain issues. I have several friends with the same 2017 or 18 truck and are having the same issue. Obviously this is a defective part and is a significant safety concern being the brake system on a heavy truck

The ABS and traction control lights keep chiming and flashing. This condition disables the cruise control as well and possibly the 4WD system. Parts aren-??t available at this time from the dealership and after doing research, this seems to be a very common problem with the 2017-2018 Ram 2500/3500 models.

ABS or EBS warning light. Dealer unable to resolve.

ABS unit is malfunctioning for the third time on the truck. The dealer has already replacement it twice but it keeps beeping for notification and flashing the ABS indicator. The Hydraulic Control Unit doesn't work, because of this I can't use Cruise Control or the 4x4 component of the truck. The Traction Control System light is on making it difficult to break properly in wet surfaces. There are thousands of people waiting for the replacement of the ABS unit, due to the 2017 and 2018 models having this issue.

ABS Module and traction control do not work. Cruise control does not work. The ABS and traction control continually blink on and off. Was told that there is no replacement part for the ABS module and that is it unavailable indefinitely.

Service antilock brake system. This problem appeared about one year and a half ago, I took it to the Dodge dealership where after diagnosis, they replaced a valve in the hydraulic system. the cost of the repair was, $800. Now as of 12/28/2023, I am having the same problem with the same code and dash brake light and stability control. We need a recall, which will repair these problems, or redesign the parts associated with this system. Now, I am driving a vehicle that is probably unsafe to use. The vehicle is a 2017 Dodge Ram 3500 6.4 liter engine, SRW. Thank you

The ABS module/HCU has failed again. I originally failed in August of 2021, it was replaced with mopar OEM parts, it has now failed again.

- Cedar Lake, IN, USA

I am getting the C-0020-01 ABS code. The ABS module and HCU have been replaced and have failed again. This is making the vehicle dangerous to stop in damp conditions.

Abs failed 2nd time less than 10000 miles after first failure. First failure just before 36000 miles repaired under warranty. 2nd failure just before 46000 miles. No parts available est for repair $1000 to $2000 dollars. Truck now has 52869 on odometer. Failure affects cruise control, and maybe trailer brakes and traction control

- Cedar Creek, TX, USA

Vehicle alarms indicating loss of anti-lock and traction control systems. Failure results in loss of both anti-lock braking and traction control safety functions Have twice had the ABS control module and Hydraulic Control unit replaced by Ram dealer. Failure returned for third time in July 2023, and have been waiting on same replacement parts since (manufacturer backorder). Vehicle has approximately 83k miles, and this issue has been ongoing since 2019.

2017 Ram 3500 intermittently displayed service anti-lock brake system and service electronic braking system notifications on the dash display while parked and driving. A local dealer diagnosed the fault it as an ABS hydraulic controller/pump failure and stated the replacement part is on backorder with an unknown timeline for arrival. They have informed me that the truck may not perform braking safety functions as intended and advised I should not drive the vehicle until the problem has been corrected.

ABS control module has been back order since June 2023. Abs light flashes and bing on regular bases. Cruise will not work when the ABS light is on. I-??ve been on a wait list since June 2023, truck is very annoying trying to drive with constant binging. Towing my 5th wheel is very concerning with on going ABS module problems.

- Canton, NC, USA

Random occurrences of an audible bell along with error messages stating, "Service Electronic Braking System" and "Service Antilock Brake System" flash momentarily on the dash. They may also stay on for prolonged periods of time. Cruise control is inoperable when the error messages flash, or stay on. The ABS trouble indicator light is also on during these events. The abrupt cancellation of cruise control in traffic is dangerous, especially when towing a trailer. The problem started (for me) just after purchasing the vehicle, used, with 27,428 miles on March 9, 2023. I suspect the pervious owner traded this vehicle on another vehicle because of this problem. I tried to get out of the purchase of this truck because of this problem. Dealer would not allow that without much expense on my end. So, I'm stuck with the problem. It has the potential to be very dangerous. Luckily, I had purchased an extended warranty but the dealer said I needed to wait a month or so before I took the vehicle to a Ram service center so the warranty would be fully established. I purchased the vehicle for pulling purposes and I do that regularly. In the similar cases I have read about, the owners say that the dealers are not helpful and the vehicle has to be kept for long periods of time for evaluation. I have not had time to get it properly diagnosed yet but the problem is exactly like the many others cases I have read about.

While under warranty in 2020 with approximately 15000 mile the ABS light and traction control light came on my truck. I was told that a new Hydraulic control unit and ABS module were being redesigned to replace the manufacturing defect, they lied at ram mopar! This is November 2023 and still no replacement parts, This issue affects the antilock brakes and traction control and cruise control and four wheel drive functions on my 2017 ram 3500 tradesman. I just contacted the local dealership parts department who told me that replacing these defective parts with new replacement parts will not work. The manufacturer must redesign the ABS module and Hydraulic control unit with with the new estimated date of July 2024 availability. In other words never!
