ABS and traction control lights on due to failure of ABS module and pump. No accident but feel there could be a problem in the future considering this is a safety issue

Service and systems and service electronics brake system warnings at approx 50000 miles. Dealer is saying it is an HCU failure

- Conway, SC, USA

At 9,040 miles, display reads -??Service Antilock Brake System-?? along with warning lights for abs and traction control and a loud dinging. It goes off, then back on multiple times until serviced when the dealership replaced the faulty HCU Sept. 2020 under warranty. Diagnostic code C0020-01 ABS pump motor general electrical failure 2023 the problem comes back but nothing done. 2024 after much research, found the newer replacement HCU had just been revised in April with a new part number. At 25,837 miles back to the dealership for another replacement, this time paying out of pocket, over $300 for part and over $600 for labor. It-??s only been a short time but so far, no warning about a faulty abs. I do have the old part if inspection is necessary. There is an FCA service bulletin out #S2005000004; NHTSA #10181550 It says if the HCU doesn-??t fix the problem, replace the ECU, but that is not available and no ETA. Lucky to get the HCU because that is a very limited part. This is a safety issue because not only does the ABS and traction control go out but you also lose cruise control and 4wd while driving. There should be a recall with all the complaints. Not sure what good a recall would do if parts aren-??t available anyway. Telling someone who just spent a fortune on buying this truck not to drive it because of this, is not an option.

Abs/traction control light. Dealer says it needs a new abs module and pump. It-??s too new to have these issues, dealer states that it is not a recall and I would have to pay out of pocket ($1600) for the repairs. This is not safe at all. I live in indiana and doesn-??t like stopping when the road is snow covered. Ram/chrysler needs to have this recalled immediately. This is very dangerous!!

Getting the "Service Electronic Brake System" alarm. Had this when it was under warranty and it was "Fixed". I am now getting this same error again. ABS, traction control and cruise control are all disabled when this warning occurs.

- Goldsboro, NC, USA

The ABS light and traction control light comes on intermittently, from my understanding this controls the stopping power of the truck. I have no traction control when I am pulling my camper. The lights will go off and then come back on own their own, even when the truck is sitting still with nothing hooked to it.
