Abs light and traction control light comes on and off all day long. Brakes will lock up if you-??re using cruise control when the abs and traction control light come on. Both lights come on at the same time. The parts needed for this issue is on back order.

my 2018 Ram 3500 had less than 36,000 miles when the anti-lock brake system and service electronic brake system alarms began randomly flashing. this happens now every few seconds and so speed/cruise control no longer functions, also anti-lock and skid prevention has failed. Dealers have 3 month back order on the Hydraulic Control Unit, leaving owners the choice of operating an unsafe vehicle, or parking it for months.

UNKNOWN. abs pump problem

- Pleasureville, KY, USA

Truck gets a service electronic braking check engine light and disables traction control as well as the cruise control. The braking becomes disabled at random times. Taken the unit to the dealership just to be told the part has been backordered for over 2 years and that they cannot sell me the HBU to repair it. They said they could remove the unit and have it shipped off to be remanufactured but my truck will be inop for min 2 weeks. Was told the part I needed 68143491AB

Dashboard ABS and Traction Control Lights come on intermittently with message to service breaking system. The lights are accompanied by loud audio alarms. The audio alarms usually cycle through a minimum of three times; sometime five. The dashboard ABS and Traction lights reset by themselves. Scanner codes identify an electrical problem with the ABS HCU and/or hydraulic pump. Dealership maintenance and service departments advise new parts are not available but to check back frequently for supply updates. If/when repair parts become available, this repair will be the second time I have endured this problem. Also, I have been able to reset the above dashboard alerts and audio alarms without the aid of Bidirectional scanner by cycling my windows down and up. So, I-??m not sure if I have an ABS/TC problem or a wiring problem.

The ABS Brake control module malfunctioned causing several electrical issues. Fortunately the vehicle was able to function. RAM Service center noted a wait time of over 3 months. When I brought the vehicle to another Service center looking to see if the part was available, I was told to make an appointment and they charged me $90 to tell me what I told them. Uggg.

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.

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.

Since purchasing this truck brand new in 2018 we have had nothing but problems with this vehicle. Dodge Ram failed us every time. They failed to work with the dealer and ignored every attempt to find solutions. It started with vehicle loosing power on very dangerous locations a specially freeway located in curves in the middle of nowhere. It took years to fix that problem. Multiple times we drove from the shop being told that it was fixed and it wasn't. We would drive right back in after 15 min. It took over 3 years to get dodge and dealer to replace the transmission and all electrical issues. The other problem that we have had since buying this truck is the AC. Its been always a problem we are continuously trying to fix it and its been very hard. This entire summer my children have been suffering. We are driving in extreme heat with zero ac and Dodge Ram can not produce part for the dealership to fix it. What is really unfair that original dealer tried again to charge us for something that it waste the problem. We would have paid for it and would have been back within an hour. The new dealer Peterson Dodge understood the problem and was honest with us that there is a lot more then a filter. It was me who requested to get a second opinion and get a way from Larry H Miller Dodge.

Anti lock brake service light came on repeatedly and vehicle was taken to South County Ram dealer in St. Louis and they scheduled a service appt in July 2022 and they indicated an antilock module was required and did not have part due to manufacturer and did not know when part would be available. The vehicle again was taken to same dealer on July 10, 2023, and same story. This was reported to Chrysler Complaint line that same day and no response from manufacturer. How can an important safety part not be available" How can they continue to produce vehicles and not have replacement safety parts"

ABS System flashes on and off that it needs to be serviced, also cruis control doesn-??t work. Took it to dealer to get it diagnosed. Dealer says the HCU needs to be replaced and the ABS pump needs to be replaced and also that cause the brakes and rotors to wear out and they need to be replaced too.

2018 RAM Display screen delaminates and behaves erratically. Car phones 911 and the call cannot be stopped. Switches driver controls erratically. All electronic systems are erratic because the screen thinks it is being touched when it is not.
