Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.

My truck is a 2018 Ram 3500 with only 12,500 miles on it, and it is not driven in the winter. Recently it has been has intermittent activation of the ABS and traction lights. It has been on consistent for over a month now. I code scan showed C0020-01 ABS module general electrical failure. I search online and talking with the dealership revealed this is a fairly common issue on 2017 and 2018 trucks and the fix with either the HCU, ABS module or both. I see NHTSA has opened and investigation into the matter so I am just reporting mine as additional truck with issues. It has not been repaired yet. Thanks.

While reviewing NHTSA's website I noticed PE22-012 concerning Loss of Brake Performance on 2017-2018 Ram 2500 and 3500 trucks. My 2018 Ram 3500 recently started giving me an ABS, traction control and/or "Service Electronic Braking System" warnings. I first noticed the ABS light shortly after I most recently rotating the tires. The tires were rotated for the 3rd time on 14 Dec 2022 with 44,158 miles on the truck. I rotate all 5 tires (spare included in the rotation). I didn't think much of it at first as I was driving in PA on snow covered dirt roads the first time the ABS light came on. After that it became more frequent with the traction control light typically also illuminating. And now more recently a message on the dash information center appears after the lights come on. The lights don't always go out after a key cycle but will often turn off in the middle of a trip. I have not taken the truck to be inspected. Nor have I noticed a degradation of braking ability. I also have never had to brake hard enough to activate the ABS on this truck, nor have I tried it just to see.

"Service Electronic Braking System" intermittently flashes in the dashboard, along with the orange ABS and traction control lights. Seems to happen more on bumpy roads, goes away on smoother roads, then randomly comes back. Over the span of a few weeks, the frequency of the error message has increased, and now the error lights stay on almost all the time. 47,500 miles and purchased new 3 years ago.

Right before 36000 miles the ABs and Traction control lights come on and off intermittently. I took the truck to my local dealer and was told 2 components needed to be replaced. They informed me it was not covered under warranty and they did not have the parts nor knew when they might get them in. This has been 4 or more months now and the lights stay on more often than they are off. I can-??t use cruise control and it will not pass inspection with the lights on.

I had a warning message to service my DEF system. I had the truck checked at a RAM dealer who reported i need a new exhaust system. They had me wait a few days while they ordered parts. The message never reappeared and the truck is running fine. I dont understand why the dealer wanted me to replace my exhaust system when it apparently doesn't need one. The 2018 truck has only 18K miles on it.

A warning to have my electrical braking system checked continues to alert me while driving along with a abs warning. I notice no change in the system braking. When taken to a RAM dealer for repair the result is to wait months for an electric brake controller. Warning message disables the cruise control.

Every time I plug in a trailer to the 7 point electrical plug in, it pops the fuse for trailer brakes. It has happened with 5 different trailers. Has also happened with other 2017/2018 Ram 2500/3500. Ram claims it-??s the trailer.

"Service electronic braking system" and "service antilock brake system" are popping up on gauge cluster at highway speeds. This is a random event that started at about 35,000. The system shuts on and off constantly with chimes and alarms to -??Service electronic braking system" and "service antilock brake system". I contacted the dealership by phone, and they said they know about this issue but there is no Recall yet and it-??s not covered under powertrain warranty; they advised it needs to have the ABS pump and control module replaced. I have looked on the internet and see several thousand complaints for the exact same issue. To me this seems like a life/safety issue that is being ignored Stellantis / Ram.

HCU unit failing. Keeps throwing service abs, and service electronic brake controller. On off on off on off non stop constantly the whole time truck is almost undeliverable Part is unavailable due to supposedly back ordered. Been told part is known issue and that a recall should be done but it-??s not. Hydraulic control unit. So driving a one ton truck with failing abs, traction control with no delivery date of a part that is junk.

HCU Issue: The ABS light coming on is the lightwill come on for two second and go off at times, through the diagnostics of the code C0020-01. It is a general electrical failureto the hydraulic control unit. The unit is replaced separate from the ABS moduel th HCU needs to be replacedfirst. In some cases, the ABS module that is bolted to the HCU needs to be replaced and programmed as well. The HCU needs replacement first. The total estimate is $1010 with labor. Any questions, please call Bruce at Albany Chrysler. 320-845-2801. This is an intermittent issue, that comes and goes.

2018 Ram 3500 - ABS system/Electronic braking system failure at 5583 miles. ABS/traction control and service electronic braking system display on dash, also audible chime with cruise control inactive. Took to dealership for diagnonis and code C0020-01 is active. Reccomended replacement of HCU which is common for these vehicles. Truck is out of warranty and estimate is $1080 for repair, which does not include the $301 I spent on diagnostics. There needs to be a recall on these Chrysler HCUs as they are a known issue and related to the braking system. Why do I see recalls on items such as malfunctioning tailgate latches but not braking systems?

ABS and Traction Control lights and DIC alarms came on while driving. They stayed on for a few minutes then went off. Also the service trailer brake system message came on. This has happened several times now turning off cruise control too. I reseated all fuses and went for two weeks before it started happening again. Happens sometimes as we go over expansion joints or hit potholes while driving at highway speeds. I notice several other reports of this here at NHTSA site and various RAM forums across various RAM years.

ABS and EBS sytem is shutting on and off on highway at speeds. This is a random event that started at about 20,000 miles then went away for about 6,000 miles then came back at 29,000 miles whil on a 1,500 trip and is now not going away. The system shuts on and off constantly with chimes and alarms to "service ABS/EBS. I have the truck at the dealership and they advsied it needs to have the ABS pump and control module replaced. I have looked on the internet and see several hundred complaints for the same issue. The delaer says this is not a recall and is not covered by warrenty. To me this seems like a safety issue that is being ignroed by Chrysler corp / Ram. They are looking at the numbers and not enough people have been in accidents to justuify the cost of a recall. I have a video of the issue system turning on and off constntly at about 62 MPH as I enetered the freeway from and on ramp to merge in trafic.

The ABS Anti lock lights came on and says check Electrical Brake System. Dealer said The ABS anti lock brake pump assembly was bad and it was on me to replace it. This is a big safety Issue to me. I got a 2018 3500 ram and paying big money for a truck and my safety, there should be a recall before some people get kill.

The contact owns a 2018 Ram 3500. The contact stated while driving approximately 35 MPH, the contact observed that the check engine warning light was illuminated and the coolant temperature warning light was also illuminated. The contact pulled over safely and turned off the vehicle. The contact drove the vehicle to a dealer where it was diagnosed and determined that the thermostat, coolant sensor, and air intake heater relay needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V798000 (Electrical System) however, neither the VIN nor the vehicle year was included. The manufacturer had been informed of the failure. The failure mileage was approximately 67,000.
