Constantly throwing ABS code and electronic braking system code, and then, turning off the alerts on dashboard. Many complaints of 2018 models were found online and a class action lawsuit.
Traction control/ABS illuminated on dash board as error codes. When driving at any speed the brakes are grabbing the rotors without touching the pedal. The feel is like tapping on brakes. I've replaced wheel bearing hubs for ABS speed sensors, replaced all speed sensors. Replaced the ABS MODULE and HCU MODULE and to no avail. Chrystler has had the main components on backorder. The error codes are targeting both components ABS and HCU. The Ram community has the same concerns as I do. This issue should be recalled because the ABS and HCU prevent from fish tailing and erratic traction
2018 ram 2500 under 15k miles. Service ABS light started coming in a few hundred miles ago.
I purchased my 2018 Ram Power Wagon used in 2020 with only 2300 miles on it. In 2022, I started to have intermittent ABS and traction control lights flashing on and off. I took the truck to the dealership and was informed the HCU was defective and needed to be replaced. The truck was still under warranty and was repaired. In Nov 2023, again the ABS and traction control started flashing. Again I took the the truck to the same dealership for repair. This time, however, I was told the truck in no longer under warranty (timed out, not mileage (26000 miles)) and the part wasn't going to be covered, additionally, was told the HCU part was not available, as it was under engineering re-design. After discussion with the service manager, he agreed that since this is the second occurrence, I wouldn't be charged for the part, just labor for the repair, however, the part wouldn't be available until the spring / summer of 2024! I asked if I could continue to drive the truck while waiting for the part to come in and was told that I wouldn't have anti-lock brakes. Obviously I expressed my concerns about driving the truck and asked if Ram was going to issue a safety recall for the part. I was told no. I am still waiting for the part and refuse to drive the truck in the rain or wet conditions.

Intermittent ABS brake failure warnings displayed in the message center and warning lamps, message comes on and off erratically. Speed Control is inoperative when message is displayed.

I have multiple videos of warnings coming on and off. Vehicle is currently at the dealer for repair 1/9/2024. The Ram dealer states the ABS HCU module failed and needs replaced. Dealer indicated this was a common issue with 17/18 model year RAM Heavy Duty's.

Intermittent ABS / traction control light and dinging! 49000 miles. Just like every other person complaining about the same exact issue on 2018s. I’m a disabled vet with a family of four on a single income. I can’t afford a 1200 abs module that lasts only 1-2 years. Clearly this is a major manufacturer issue, experienced by many Americans.

After much research and blogs this 2018 2500 diesel turbo has a problem with its antilock braking system module. I have taken it to several places since the light keeps going off and on and have no solutions since this part is on back order. I need to find a solution for this truck. Please advise someone.
My truck has an intermittent ABS light along with a traction control light and a message displaying Service antilock brake system and service electronic brake system. these lights also sometimes stay on until the next ignition cycle or even several ignition cycles. it also disables the cruise control as well causing an extreme loss of speed on the highway especially when traveling up steep grades. there were no issues leading to the cause of the lights to come on to my knowledge and i have not visited any sort of dealership or service center regarding this issue nor do i have the time or funds to correct this issue at this time.
abs traction control light abs brakes dont work
The following messages suddenly came up on my screen. Service electronic braking system, service ABS system. Then the following warning lights came on. Traction control warning, ABS light, tire pressure unavailable, parking sensors unavailable. The cruise control is also unavailable. It is winter here in MN and I thought it would be ok until I get it fixed, I will just use 4 wheel drive. 4 wheel drive is also not available. Am not able to get the vehicle repaired, parts on national back order for months. Do not have a backup vehicle. Have to drive an unsafe vehicle to and from work in winter conditions. Can’t lose my job.
The Anti-lock Braking System (ABS) and the Hydraulic Control Unit (HCU) issue is present on my vehicle. The problem is intermittent and occurrences cannot be predicted, duration fault varies, sometimes repeatedly cycling fault/no fault/fault etc. When the fault occurs cruise control is either canceled (if active) or not available. Occurs at varios speeds. Please refer to the federal safety agency's open investigation (the federal safety agency Action Number: PE22012).
The abs and traction control keep going in and out and is very unsafe to drive such a large truck. I called dealership and they don’t have the abs module and haven’t had it for over a year. So they know it’s an issue and can’t give us any since manufacturer is at fault. My abs and traction don’t work. Thank you
ABS lights go on and the truck chimes sometimes, not all the time. Cruise intermittently does not work as well. This is a well-documented issue online. I took this to the original dealer and he said this is a common problem. Even after getting it fixed, it will occur again. The dealer said it is still supposedly safe to drive, but it is very concerning to see ABS warning lights regularly popping up on my dashboard. Many others have parked their trucks and are not driving them because of this issue.
The ABS keeps going off and this is the second time. I read reviews and this is a known issue, that needs to be recalled.
The ABS controller has been replaced twice and has now gone out again. When this happens it turns off the ABS, traction control and cruise control.
