ABS system - flashes on and off dash, ABS has been inspected by dealership. Dealership said, could replace ABS but it could very likely have the same issue due to part malfunction. This malfunction causes- no cruise control, no traction control, sounding and lighting up on dash constantly.

Bought from a dealership a couple months ago (JAN 2024). Immediately started blinking electronic ABS error. Took in to get serviced, and now maintenance department is stating a replacement HCU and additional service will cost around $3.5k on a vehicle that has around 68k miles.

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.

The known issue that Ram refuses to is plaguing my truck. ABS and Traction Control lights come on. This shuts off the cruise control as well as makes braking difficult. It is very dangerous. This is a ticking time bomb. Vehicle has under 50k miles on it. 2017 and 2018 have been known to have faulty ECU Module and HCU. Loss of brakes momentarily occurred on [XXX]. I am having the issues under investigation. NHTSA Action Number: PE22012 Components SERVICE BRAKES, HYDRAULIC Opened From: November 28, 2022-?"Present The reports cited below can be reviewed at NHTSA.gov using the following ID numbers: 11143741,11182778,11231734,11252781,11265590,11270151,11300182,11319987,113409 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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!!

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.
