ABS/Trac lights ding constantly with the dash displaying "service electronic stability" or something along those lines. ABS system becomes inoperable as well as kicking your cruise control off. Very unsafe and parts are not available for repair as well as Ram not taking recall action up to this point.

HCU / ABS module issues. Truck while driving has no cruise control my lights stay illuminated all the time, truck only has 57,000 miles and already repaired all 4 abs wheel speed censors, spent countless hours visibly checking all wires and fuses make sure no defects there. This could be a very dangerous and life threatening situation and I would think it's only right for Dodge Ram to recall the 2017-2018 for this ABS issue.

May 2023

The Anti-Lock Brake control module along with the Hydraulic control unit is failing. At any rate of speed, the traction control light and the ABS light comes on and off repeatedly. When this happens, the cruise control disengages which has cause the truck to slow down rapidly in heavy traffic causing other drivers to almost rear end my pregnant wife, 3 year old son and I. I had my local ram dealer pull the Diagnostic Trouble Codes and confirmed that the parts stated above, were in fact failing. The messages that pop up on the instrument cluster are “Service Anti-Lock Brake system” and “Service Electronic Brake System”. I can not have this component inspected as it is a daily driver and is the only vehicle we have currently.

The ABS, traction control, cruise control and 4x4 no longer function. It started intermittently and now is constant. The vehicle is available for inspection. After a hard stop the abs won’t engage and I lost traction of the truck. There are two warning lamps that are on at all times (abs and traction control). It has been ongoing for almost 1 year and 10,000 miles or so.

Driving down the highway with the cruise control set and all of a sudden the cruise control stops working and my dash is dinging with service ABS system and service Electronic Brake System. The truck had 78,500 miles when this first happened. Now it does it intermittently while driving down the road. I notice there’s no recalls and it sound like a large problem. Haven’t taken it to a dealer yet.

At 36,000 miles have been told I need to replace ABS pump control general electrical failure. Also replace ABS module. Parts are not available and are on backorder. I pull a 25 foot camper and this issue is causing concern with vehicle stopping. Apparently is a big problem as parts are not available and dealers that have part will not release parts so my truck can be fixed.

ABS / TRACTION CONTROL LIGHT ON IN THE DASH. CRUISE CONTROL INOP. THIS IS A KNOWN ISSUE, IN FACT 2019-2022 TRUCK HAD A RECALL ISSUED. RAM NEEDS TO ADDRESS THIS SAFETY ISSUE

Intermittent ABS, EBS and traction control issues causing spurious warnings and loss of cruse control. The alerts are distracting to the driver, loss of ebs/abs represents safety issues while traveling, as does the loss of traction control and cruse control. Dealer has diagnosed the issue to the respective abs/ebs controllers but reports no parts in inventory and no due date for when they will be available. Formally request NHTSA force a recall to require the mfg to correct the issue expeditiously.

The vehicle experiences intermittent fault displays for "electronic brake service" and "ABS Service". This causes the vehicle to suddenly come out of cruise control and slow dramatically. This causes the vehicles ABS safety function to be inoperative reducing the overall braking capability and increasing the safe stopping distance This causes traction and stability controls to be disabled further degrading the built in safety features This was diagnosed several months ago by the dealership as an ABS hydraulic pump problem with no parts availability. The lack of parts has been an issue for months and has rendered my vehicle inoperative. The dealer said this was a common problem and that they had multiple Ram trucks with the same problem. I also checked online and found multiple reports of the same issue across the brand and across the country. This is a significant and costly repair >$800 for a part which is clearly underdesigned for the applicaiton with poor or little reliability.

ABS and HCU are in need of replacement parts. Because no replacement parts are available, I have no choice but to drive a Truck with questionable Breaking System, putting me, my family and others at risk, since the brake system is what stops my Truck when I need it to stop or slow down. I use this to tow the family travel trailer as well. This is also very important when brakes are needed to function safely. I have taken the Truck to my dealer of purchase. They completed a diagnostic test and also reproduced and confirmed the problem. The vehicle has been inspected by the manufacturer's dealership Service Dept. The Truck's "ABS SERVICE BRAKE SYSTEM" warning lights and warning tones alerted me of service needed back in November 2022, with just over 36,000 miles. I made an appointment and the dealership serviced my truck in January 2023. Since no parts are available for the repair, I had no option but to pay a diagnostic's fee to have my vehicle released to me, still in need of repairs. The warning lights and signals continue to go off repeatedly whenever I drive my Truck, letting me know that there is a SAFETY ISSUE THAT NEEDS TO BE FIXED!

ABS light and traction control warning on dash. Truck has been in shop previously for the same issue. This causes my truck to lose cruise control at highway speeds and to not have traction control capabilities when driving on wet roads. I will be taking the truck back in to the shop this week as this is occurring at all times and does not stop dinging.

Service lights for ABS and traction control systems constantly going on and off during vehicle use, these system failures disable cruise control systems. Truck is at dealer and they have said it needs new hydraulic control unit and ABS parts totaling over $2000 in parts alone, without an idea of when the parts will be available. This seems to be a common failure as I have read many posts of other Ram owners with the same issues.

Abs braking system has been flashing and traction control light flashing. My left front wheel started grinding and smoking out of the blue when driving today. No problems with brakes before that. Cruise control doesn’t work. And four wheel drive service light is flashing again!! The four wheel drive sensor was replaced once already a couple years ago.

Was driving vehicle on a rock road, when rounding a slight curve in the road, the antilock brake system light and the traction control lights both illuminated at the same time. The rear end of the truck began to slide due to having light pressure on the brakes and I was pulling my fifth wheel camper. Fortunately there were no injuries or damage to the truck or the camper. I washed off the mud when I got back to a hard surface area that had a car wash available and continued on my journey. Approximately 30 more miles later on the same trip both warning lights came on again. I immediately pulled over to read the message warning that was up on the dash to see if I could continue with my journey or not. After reading the message on the display in the truck, I decided it would be safer not to continue with my journey with that truck due to the safety issues and possibility of injury or death to me and my passengers, or another vehicle that I may encounter either head on or from behind. I had a friend of mine bring his fifth wheel truck to pick up my camper and return it back to my home. I had to cancel my camping trip for that week, which cost me approximately $400 out of pocket and then I had to pay my friend gas money to bring my vehicle home for me. I placed a call to the dealership nearest me and they advised me it would be $1,000 to begin any sort of diagnostic procedure on the I have now been driving the vehicle only unladened with any sort of extra payload, the light will come on and go off and come on and go off multiple times some days no times other days. I am retired, and a long-term covid patient, I do not have the financial resources to take a vehicle to a dealership to have them charge me absorbent amount of money when this clearly should be a safety recall on this vehicle. I have lost use of the vehicle for the intended purpose of telling my camper and boat, the manufacturer needs to be advised of this and give everybody repairs to make it safe to use.

There seems to be a huge ongoing problem with ABS pumps and control modules for this model vehicle. I can find pages and pages of issues online for the same truck. The 'service brakes' warning comes on and off intermittently and I managed to replicate the fault after several months long enough to get it diagnosed. I am told the following parts are the issue: 68347098 - AB MODULE AN 08035030 68143491- AB CONTROL A 08035030 I got the truck diagnosed in January but was initially told Mid March for the parts and now am being told August - which would mean no functioning ABS on my vehicle for 8 months! And no guarantee the delivery date won't creep again. This is unacceptable for a safety critical component and clearly shows a fundamental flaw with the parts as they can't seem to make them faster than they are failing. I can find many reports of these happening from as early as 14,000 miles and with the replacement parts also failing.

ABS and Tracton control

Incident: Feb 2023
Feb 2023

Driving along freeway to visit family, cruise control engaged, travelling 65 mph, when all of a sudden several messages flashed on the dash to "check electronic braking system", and traction control disengaged light and service light came on as Cruise control shut off. after a few seconds lights went out and system returned to normal. Repeated several times on way back home (3 hr drive) and had randomly happened since almost every time I drive the truck. Had similar situation a year after I bought the vehicle, 11/2020 @6600 miles, local dealer replaced HCU. This can potentially leave me without Traction control and ABS when I need them and could cause an Accident. I'm waiting for dealer to get other parts in for a covered warranty repair, (Been waiting since Nov 2022), and have them fix both, again, but it renders my truck useless- dangerous to drive until then.

The abs module and hydraulic control unit has failed. This means that my safty and others on the road is put at risk because during heavy breaking you can loose control of the vehicle due to the truck anti break system does not work. Also the traction control does not work which also will cause you to loose control.

The abs and traction control light are flashing on and off SEVERAL times especially when on a rough road. It kicks my cruise off and sometimes stays on which locks the diff and disengages any ABS functions resulting in the loss of braking performance and capability.

ABS and stability control fails and warning lights activate intermittently 11/11/22 (47,290 miles) The cruise control disengaged without notice when the faulty modules light up. Under a heavy load this caused severe speed reduction and momentary loss of vehicle control Reported to dealer.(Rothrock motor sales) It is a know issue with thousands of suspect ram 2500's Parts are not available due to demand. This is an intermittent fault with the Stability control and/or hydraulic control module. Both parts or one part faults the other creating a hazard for all drivers Dealer was made aware of issue and states parts are back ordered months out if at all available causing customers to drive the trucks with unsafe braking due to no other means of transportation This is a well know defect being ignored by Chrysler/Ram

Anytime while driving the truck waring lights on the dashboard will come on intermittently. The ABS and traction control light will come on, and on the display screen two different messages will appear along with alarm sound constantly dinging. One message says (Service Electronic Braking System) the other says (Service Antilock Brake System). If driving with the cruise control on when those lights and messages appear the cruise will stop working. This problem is intermittent it comes and goes, but usually very often. The truck is out of warranty with 41000 miles on it and this has been happening since Sept. of 2022. I had it diagnosed by an independent garage and had two trouble codes (C0020-01 ABS Pump Motor Control General Electrical Failure) and (C0020-16 ABS Pump Motor Control Circuit Voltage Below Threshold). The truck still seems to stop normally, but I feel very unsafe driving it. The ABS Hydraulic Control unit is unavailable from the dealer. As of today Jan.-18 2023 they are saying it will not be available until March-15 2023. This is most definitely a safety issue on the truck which should be recalled. The dealer says the parts problem is a supplier issue. I believe the manufacturer knows these are defective and is trying to avoid recall.

For about 8 months, our 2018 Dodge Ram 2500 has had interment ABS and HCU warning lights and the notification to "Service electronic braking system" followed by "Service antilock brake system". This may occur for a period of hours or seconds and disables our trucks ABS, traction control, cruise control and other systems. When checked, the truck has no stored fault codes. When this first occurred, I went to the dealer where the truck was purchased and inquired about replacement ABS and HCU modules and was informed that none were available. After subsequent visits and internet research, I found TSB#C0020-01, "ABS Pump Motor", that directs replacement of the ABS/HCU modules, and directs that the replacement parts will be provided by a "STAR system". We have had three incidents that we narrowly avoided accidents, two due to the intermittent ABS failure and one due to sudden loss of traction control while pulling our trailer. It has also noted that a Class Action Lawsuit has resulted from this same issue.
