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.

ABS control module has failed part number 68347098AA this part has been on back order for over a year dealers do not have a firm date on the delivery, This is a safety issue that dealers can not repair.

- Cleveland, OH, USA

Abs and traction control lights come on and off at intermittent times while driving, cruise control is lost when these lights come on, this has been an on going problem for about a year now but is a near constant every time I drive now starting about November 2023.

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.

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!

I have a 2017 Ram 3500 and continue to have problems with the ABS brake system. At 17036 miles on 10-08-2020 I had an ABS failure warning light. The Ram Dealer replaced the HCU module which seemed to fix the ABS failure for a short time. At 35832 miles in November of 2023 I am once again getting a ABS warning light. The Ram Dealer now recommends replacing the ABS module and the ABS Pump. ABS failure should not be happening repeatedly on a low mileage vehicle.

Like many others, I am experiencing the Service ABS light coming on which not only disables the ABS system but also disables the cruise control. The chiming of the warning goes off every few seconds and can be extremely distracting. With the ABS no longer working, I and my family are at risk since we use this to tow a 14,000 lb. fifth wheel. I have taken this to a Ram dealer and the diagnostic is the ABS Module / Hydraulic control unit failure. Ram has known this is an issues for several years.

Service Electronic Braking System and Service Anit-Lock Braking System alarm lights. Code C0020-01 ABS Pump Motor Control- General Electric Failure. This issue is related to Anti-Lock braking that can cause injury to my safety and family safety. Problem is very well know and fully reproducible at dealers. Vehicle has been at dealer for long term waiting for dealer to find/repair issue.Dealer is at loss for repair. Dealer repair for this was change HCU and ABS Module. This repair has shown to not work in many scenarios and multiple repair and replace of the same units are not fixing the issues.

While driving the vehicles message display center says "service emergency braking system", the traction control indication light turns on and off, the abs indicator light turns on and off, the park sense indicators turn on and off, and if cruise control is on it is deactivated and turns on and off. An audible chime indication is also sounded when the message center displays a message. With the traction control and abs turning on and off creates an extreme safety problem especially with the winter months ahead. The vehicle has not yet been looked at by a anyone but an appointment has been made with the local dealership. This first started while driving on 11/11/2023. However, the indicator lights and chime still occur while the vehicle is in park and motor running.

ABS module and Hydraulic Control Unit have both failed multiple times. Known issue to RAM with no recall issued. Advised not to drive the truck until the parts are available as the brakes may completely fail unexpectedly, leading to loss of stopping ability/accident.
