Ram 3500 Larime Crew Cab Deisel with 47,800 miles. We were driving home from our seasonal campsite, (about a 2 hour trip on highway) and it began to rain (about 15 minutes into the trip) it continued to rain very hard at times the whole trip home. Around 30 minutes into our trip the ABS warning light, Check Engine light, & Traction Control light came on. I pulled to the shoulder of the road and waited for a lull in the rain. I then opened the hood and inspected to see if something was shorting out electrically. I couldn't see or smell anything, so we decided to continue on our way. We exited the highway and took non-highway route home. I did not notice any issues while braking or driving that concerned me enough to have it towed. I pulled the truck into the garage (under our house) and unloaded our belongings from the weekend. I went down to the garage about 2 hours later (the key fob was upstairs) when I walked behind the truck, the cargo light and interior lights came on. This didn't make sense to me because the key fob was not anywhere near the truck. It was still raining so I decided to disconnect the batteries (2 batteries on the Cummins) rather than put the truck outside in the rain. Didn't want to take the chance of burning my house down. This was the first time this has happened (7-16-2023) I research to see if anyone else had similar issues and found a considerable number of owners with this similar complaint. The vehicle has not been taken to the dealer as of this writing. Having to pull to the side of the highway during heavy rain, put my family and others at risk. Given the number of complaints that I was able to read, I would say these issues should warrant a recall.

Abs/hcu faulty, brake warning light, message, and alarm will sound on and off while driving. I have tried to buy the parts and they are not available through dodge with no estimated availability. This has been going on for a year.

In July 2022 our 2018 RAM 3500 Diesel 4 by 4 truck started having an intermittent alert. Service electronic brake system, ABS, traction control. Cruise control is disabled during this alert. May 2023 the vehicle was taken to local dealer for a diagnostic. They revealed no codes were revealed answer was to replace the ITBM at a cost of $921. And the diagnostic charge was $233. I tried to contact the dealer for further questions with no cooperation. I started investigating and purchased a code reader at my own cost. The code that showed was C0020-01 ABS Pump Motor Control-Electrical Failure. Much different than the ITBM I was told. Fiat Chrysler Automobiles put out a Case Number: S2005000004 Release Date 04/28/2020 Symptom/Vehicle Issue: C0020-01-ABS PUMP MOTOR CONTROL- GENERAL ELECTRICAL FAILURE Discussion: Basically says to replace HCU first and then ECU if code still active. So, the dealer is aware of the issue and outright lied to me. There is also an active Class Action Lawsuit for this very issue In California Plantiff James Neu. The fact that my vehicle is not in a safe working condition with this faulty part. The fact that the Dealer is lying about which part is defective and would have installed a different part than what they said the problem is. It is very disturbing that an automotive company is treating the safety of their customers so carelessly. The Fact that this is a common and widespread issue and nothing is being done to rectify, appalling. Thousands of vehicles on the road, no parts available. Action needs to be taken. Lives will be lost, severe injury, it can happen to innocent people. Please do something

Service ABS, traction control, ESP, ABS lights come on. Vehicle constantly beeps. RAM dealer says it needs a new HCU/ABS module (on national backorder) and/or ABS pump. Second time this has happened. Vehicle now at 77k miles and it happened all over again. If this is happening regularly then something must be defective with the parts they are putting on the truck.

While driving at any speed the abs and traction control lights start flashing and a chime goes constantly. also when this happens it causes the cruise control to disengage without any warning. Also leaving you without abs brakes. I am on my 3rd abs module and 2nd hydraulic control unit and needing a 3rd hydraulic control unit for this vehicle with less than 62,000 miles the first one went out around 16,000 miles and the second at 37,000 miles. This is also my second truck from this manufacturer to do the exact same thing that happened at 30,000 miles and had another one in the family that did it at 7,000 miles. As i research online I find that this a common occurrence and nothing has been done to resolve the issue other than just replacing the parts with new and wait for it to happen again. I am in need of a new hydraulic control unit and am being told that they are on some kind of hold until the earliest date of August and just to drive the truck with non-working safety equipment.

September-October 2022 --The Anti-Braking System module has quit working. (ABS). Requested replacement part from Dealership in October 2022. Dealership advises Mopar cancelled parts request to them. I have no anti braking working on vehicle. Dealership advises me to contact Mopar directly for help. I advised them that wasn't my job it was theirs'.

I have two warning messages appearing on my dash. Service Electronic Braking System and Service ABS System. Took it to my dealership Michiana Chrysler Dodge Jeep Ram FIAT in Mishawaka Indiana. I was informed that it needed an HCU (hydraulic control unit) and that the part was unavailable because of engineering review until at least August 2023. The work order was closed and i was sent on my way and told to check back at a later date for availability. After a little reading i found that this issue is under investigation and i wanted add my truck to your list of reports.

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.

ABS Brake Module and Electronic Braking Module are issues warnings. Unknown

- Bushnell , FL, USA

"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. Here is a video of what happens: https://photos.app.goo.gl/hZ3GAAq3UryvgJWV9

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.

ABS Control Module and/or Wheel Speed Sensors is causing the abs warning light and traction control module light to go on and off intermittently for over a year causing the cruise control to not engage or to disengage-??

- Andrews, TX, USA

"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.
