Related to the known HCU failure on these vehicles. My first submitted complaint was on Oct 22, 2022 and this issue is still not resolved. I received a letter in mail on January 21st of this year stating that a recall was finally underway. Now it's late March and everyone's standard response is "No Remedy Yet". The remedy is actually installing HCU part number 68143491AB which replaces the corrupt factory installed part 6814391AA. These parts are readily available online so why can't factory service centers begin replacing these failed HCU's. This complaint is filed due to my belief that this dangerous safety issue is not being resolved in a reasonable, timely manner. Not even close.

Warning lights for the ABS and the Electronic Brake System illuminated while driving, stating the systems must be serviced. The Cruise Control would either turn off or become nonfunctional. The tone would sound and the warning lights would illuminate. I took the truck in to the dealership after it happened but the lights would not come on while I was there. The dealership told me they could do nothing about it. After that, the tone began to sound and the lights came on again. We finally made it to the dealership when they could see the warnings. The service technician inspected the ABS and found that the ABS HCU had shorted internally. Further inspection found the ABS Module also shorted internally. Two trips were made to the dealership because the dealership did not have the parts in stock. This occurred at the same time as the cyberattacks which affected parts delivery and we were not notified the parts were in for over a month. The cost of the these two visits were over $1,400.

Abs and electronic control system lights intermittently come on and off constantly and have been for 25,000 miles. When it started happening Chrysler knew what the problem was hcu and abs module is malfunctioning but unfortunately no parts were available and couldn’t tell me when they would be available. I’m just now putting in the complaint due to just learning about this site.

ABS, Cruise Control and Traction control warning lights constantly flash on dash informing me that they are disabled. Dealer is saying that Ram canceled their part order for the ABS module part number 68347098AC needed to do the repair with an estimated 1 year date before it is available. Truck is unsafe to drive due to ABS and traction control being inoperable and was warned I may be liable if I choose to drive it and an accident were to happen.

From what I understand these Ram Pickups have numerous problems with the ABS module and HCU unit going out and our truck has had the same problem we had to replace the HCU unit at only 10876 miles on November 4. 2020 and now we have had the ABS warning lights coming on and took to dealer on 10/11/23 with only 22287 miles and they say we need a ABS module, we are told this part 68347098AB is on back order and as of January we still have not received it and now dealer is telling us they came out with new part number. For ram not to be able to provide parts to fix their defective braking system parts is a safety issue and Ram should make this an urgent recall issue and pay for the replacement. You cannot find the part anywhere and Ram Truck owners are having to drive with dinging warning lights and unsafe braking issues.

The ABS light intermittently comes on/off. It pops up while driving, but goes away. Sometimes it goes on/off several times on short drives. I need to know if this is going to lead to an all out failure of the braking system or something else. I confirmed with the dealer, where I purchased the truck, that it's a known issue and the part is on national backorder. Based on my research, this appears to be a common issue with Dodge Ram trucks built between 2017 and 2021. I need to know what my options are since I plan to purchase the needed part(s) at my expense since my family's safety is at risk.

The service ABS braking system warning flashes on with a chime frequently when driving. This started 3 weeks ago. According to the Ram Forums this is a common problem with 2018 trucks. My truck is a 2018 with 352623 miles on it and according to the Dick Hannah dealership a part that is out of warranty. There is no replacement part since the original inventory was all pulled back from the dealerships to the manufacturer due to the incidences of failure. This information was given to me by the Dick Hannah parts manager. He said a newer more reliable version of the brake module is being built but replacements are not expected for at least 4 months. Ram knows the part is and was defective, i am out of warranty and have a dangerous truck to drive for the next 4 to 5 months then a estimated $1500 repair bill. I want Ram to pay for this and to expedite the replacement parts and the NHTSA to do their job and serve us the consumer instead of the manufacturer. I am seeking legal recourse too. I attached the repair code report derived from my Blue Driver code reader tool.

ABS Pump motor control - General electrical failure that causes the warning lights on the dash to illuminate and an audible chime. Occurring sometimes several times in a row, which distracts operator from safe operation of the vehicle with flashing dash warning lights and audible chimes, affecting in the operation of ABS SYSTEM if required for safe emergency stopping in an emergency situation. Yes the problem has been diagnosed by a dealer ECU: ABS, CODE: C0020-01, DESC: ABS Pump Motor Control- General Electrical Failure The Manufacturer has and is aware of the batch of failed components as per various website forums. And dealer says the components for repair are unavailable for sometime. Uncertain exactly when warning lights started to flash generally, October 2022

ABS and traction control lights flash and ding on and off. Trouble shot it at dealership and wires were repaired hoping that would take care of it…. Nope, lights and dinging are back on. I tow a large gooseneck horse trailer up and down steep hills with sharp curves, across many state lines. We have the truck full of young children ready to show their horses - hence we have the crew cab. I’ll be towing within the month. I figure it must not be a safety issue - Parts are on back order until August??? We only have 40,000 miles on the truck. I can do without cruise control, but would like a safe braking vehicle - glad my husband got a stick shift to help control speed.

ABS Module Failure, This has been a re-occurring issue that nearly caused an accident. The abs and traction control lights come on intermittently and disables the ABS/traction control emergency braking system. The issue has existed for 2 months, the dealer tells me it needs a new control module which is not available till some time in 2023. There advise was watch my following distance and maintain lower speeds. Unfortunately yesterday the light came on and stayed on for 50 miles plus, due to an accident on the highway all traffic had to stop quickly, when i applied heavy braking my wheels locked up and the truck started to slide sideways, i was able manually get control by fluffing the brakes but had i panicked i would have had a collision. when i got the truck to a full stop i was inches from a small compact car. There's no way to fix this and its going to cost lives for this very widespread issue with the dodge ram 1 ton pick ups, where's the recall does this need to kill a few hundred or a few thousand people before its addressed.

I was driving at highway speeds when the abs / traction control light came on. Notice cruise control was inoperative. The next day the warning lights were off. On the way home from work the system quit functioning again. After diagnosing found codes C0020-01 & U0403-00. ABS control module failure. I was told by the dealer this safety issue was not covered under warranty.
