ABS and traction control warning lights come on sporadically.

- Virginia Beach , VA, USA

ABS faulty. No solution from dealer to correct so chime continuously, lights on dash and ABS not functioning. Part on back order with no foreseeable stock date and new parts are not correcting problem anyway, according to dealer. Here are additional notes from web: 2018 Ram 2500 ABS/HCU problem. Code C0020-01. 10/2022 Class action law suit filed in Texas for 2017-2018 Ram 2500/3500. 12/2022 NHTSA open investigation into the 2017-2018 Ram 2500/3500 trucks. 4/28/2020 FCA issues -??Diagnostics for this DTC are currently under review. When working on a vehicle with an active C0020-01 and testing leads to replacement of both the HCU and ABS Module, order and replace the HCU first. Do not order or replace the ECU. Follow Service Information to replace and bleed the HCU. Then perform a test drive. If the DTC C0020-01 did not reset- repair is complete. If the C0020-01 did return active, replace the ECU and return the parts to FCA.-?? However nobody at my dealer has heard of break issues on the 2018 Ram 2500. Common enough of a problem FCA sent out communication with the dealers on how to fix this issue.

"Service ABS"; ABS & Traction Control lights & chimes come on. This is random, sometimes for hours at a time and sometimes for days without. I've researched and have found this is very common with 2016-2018 Ram trucks.

Hydraulic Control Unit and ABS Module need to be replaced for the 2nd time.

- Clinton, MS, USA

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.

- St Johns, FL, USA

ABS braking keeps flashing and brakes are intermittent. The module was replaced by Ford dealer a while back. Truck only has 118k miles on it but continues to be a problems. I have not contacted dealer yet due to the time they take to do anything.

Loss of brake performance NHTSA action no. PE22012. Intermittent random dash warning -??service electronic braking system and ABS-??. Loss of cruise control and 4x4 functionality when lit as well as trailer brake control. Started Nov 2022 and currently continues. Will go weeks without problems and then problem will restart. Many issues listed on Internet forums regarding same. This should be a recall before someone towing a large trailer (as these trucks were designed) loses brake functionality due to a known problem and causes severe injury and/or death. Vehicle currently has approx. 45,000 miles. Multiple forum responses on internet have had parts replaced multiple times in similar mileage

ABS lights come on with the traction control light. It also beeps each time you hit the brakes when lit. It has affected my cruise control as well. Sometimes the brake will skip when you hit a bump while braking. I have had the ABS Pump and Module replaced by a dealer on September 20, 2021. It is now doing the same thing and I had an independent repair shop inspect the truck and they found the ABS pump and module defective again. It has only been a little over a year and a half and only about 15000 miles. Dealers and the independent shop both say there are no replacement parts available at this time and it has been a big problem for Ram. I don't feel safe pulling my 41 foot fifth wheel let alone the truck itself if it malfunctions while braking. I am available for questions or inspection if needed.

- Green Cove Springs, FL, USA

Both my ABS module and HCU are out. The parts cannot even be ordered till late August 2023, my truck only as 17K miles on it. This is very much a safety issue, both of the units control the ABS system and the traction control.

- Fallbrook, CA, USA

Ram truck was taken to dealer December of 2022 with 7,000 miles due to ABS lights on dash. The dealer Larson Dodge ordered a new part and said they would not be able to complete it until March and to "drive it as it is". The vehicle doesn't have functioning anti lock brakes etc. Now they have told me it will likely be August due to Chrysler being the problem. This is obvious far too long and now I'm out of options.

This is the second time my ABS electronic braking module has failed in this truck. I hope I'm not one of the only owners to complain. I've read hundreds of complaints. This is May first and it's on backorder til August. It's not safe towing anything with the ABS inop.

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.

The HCU and ABS module for 2018 and 2017 model years of the ram 3500 and 2500 are a known issue that should be recalled. There's some type of issue where the ABS and the traction control lights will turn on affecting the safety of the vehicle. Many people have the issue if you do a quick search on any RAM forum. From my understanding there was a design change on the replacement part. The easiest and probably most common fix is to remove the fuse for the ABS.

- Reynoldsville , PA, USA

ABS and Traction control lights have been on/off for 60,000kms approximately, have had it to the dealer approx 8 times for this issue, still unresolved. Traction control acts extremely odd at times and break pedal feels "soft" at times. Lights on dash come and go intermittently and so does the "soft" break pedal feeling. Warranty is now up and dealer continues to want to replace random parts @ my expense.

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'.

The service electronic brake light freq comes on. Dealer said it brake "module" needed changing and did. they also charged me $800 for it. Vehicle is still making the claim that the elctronic braking system still needs servicing almost imediately after repair.

ABS and HCU Warning lights come on and off. Looking around the internet this is a huge Problem. Took it to a local Ram dealer today and was told its a $1600 out of pocket cost seeing the truck is just out of warranty (of course) with 37,000 miles on it. Driving with the cruise control on it throws the warning lights on and off and cruise stops working. It seems the brakes are weak too. The dealer also informed us today they could not even get the parts to fix the problem until at least August! We also had to pile another $1500 in it a few months ago because the 4wd did not work either.
