HCU antilock traction control unit, warning lights on.

- N. Ft. Myers, FL, USA

ABS system and Cruise Control cut out on my truck constantly when I-??m driving. My brakes have locked up while I was driving in the rain almost causing me to wreck. I-??ve seen other people having issues with this and their HCU units in these year trucks. Ram refuses to help me.

ABS and traction control failed causing me to lose control on an icy road. I was able to regain control without hitting anything or having an accident but now I get an intermittent ABS control module service warning. When this appears the antilock brakes, the cruise control and traction control do not work. Once the light goes off all systems return to normal operation. It is intermittent and unpredictable. Parts are on National back order, I do not think replacing all of these parts is the issue. As dealers like to do-?? they just replace the whole system without identifying what the issue is. I do not think I should have to pay for replacing parts that are working properly. FCA needs to recall all of these systems and replace them at their expense!

ABS & Traction Light flicker on & off randomly at no specific duraction. I cannot predict when lamps will come on, also cruise control is disabled when lamps light up. I understand this has been an on-going issue for Ram.

ABS module and traction control starting going off while driving. I took the car to the dealer but refused to fix it despite being under warranty at the time. The ABS and traction control lights go on/off suddenly and my cruise control shuts down and I loose ABS braking which is CRITICAL. this can cause an accident and I am not the only one with this issue. 2019+ Rams have already been recalled for the same issue. I need to get fixed ASAP, I HAVE CHILDREN IN THE CAR WITH ME! Issue keeps getting worse and lights come on more and more frequent, so most of my driving is without proper brakes.

The ABS module has to be replaced!

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.

(9/17/19 (5000 miles), 11/12/21 (21,527 Miles), 3/20/23, 33,000 miles). 2) Traction Control fails, Anti-Lock Brake System fails, and Speed control if engaged kicks off! All which could lead to ineffective braking, loss of control and inadvertent speed control disengagement. 3) Yes. Cameron JCDR dealership, Cameron, Texas, Mac Haik JCDR dealership, Temple, Texas. 4) Not at this time. A case has been started through Ram. Case # 85736004 5) Yes.

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.

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.

2018 Ram 2500 6.7L Cummins. While driving, at any speed, -??Service ABS-?? and/or -??Service Electronic Braking System-?? flashes rapidly and intermittently on gauge cluster display. During this, the -??Traction Control Fail-?? icon displays. Additionally, the cruise control will automatically disengage (creating a safety issue through increased risk of being rear ended while at highway speeds) and the warning chime activates constantly leading to distraction while driving. The truck is essentially undriveable. It is incumbent on the manufacturer to remedy this problem. It-??s a shame I cannot use this truck more than a few miles at a time. How am I to stop with my family of 6 inside the truck, towing a 10,000 lbs trailer on a rainy day at interstate speeds without functioning ABS? This is a serious design flaw and I encourage NHTSA to continue their investigation into Ram-??s process for remedy as soon as practical. Strongly recommend mandatory recall.

abs trailer brakes traction control works on and off

ABS traction control warning comes on intermittently. This causes cruse control to disengage intermittently, and causes braking and traction to be compromised at times

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/traction control lights come on and disconnects the cruise control dangerously wen pulling a trailer, code is c0020-01 this is a very common issue with these trucks parts unavailable, I-??ve talk to many other owners with same issues please address the problem before someone gets hurt thanks.

A warning light comes on that there is a failure with the anti lock brakes and electronic braking system. The cruise control will also fail to work. When the roads where wet the other day, i was sliding to avoid hitting deer that began crossing the road. It took longer to stop than it should have. I'm concerned that living in Michigan with the inclement weather, it may cause a accident that could have been avoided. The vehicle was checked by a mechanic who said the control was going out. The incident started some last summer (I only have 22,000 miles on my truck) but it is intermittent.

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.

My vehicle has 45347 miles. It started throwing "Service Electronic Braking system " and "Service Antilock Brake system" messages intermittently. While driving on highway, truck would abruptly throw these messages and turn off ABS, EBS and also cruise control. It appears to be a very common safety issue with 2018 RAM 2500. I took my vehicle to the dealer but he couldn't read the codes because they were off and didn't come on. This is a safety issue for driving a one ton pickup truck and especially if driven in wet conditions.

ABS / HCU System Failed. My safety was directly impacted. I was driving 70MPH on the expressway and had a SUDDEN deceleration, which nearly caused a rear-impact collision. Various warnings and lights on the dash lit up with "Service Electronic Braking System". When the ABS / HCU system has an issue, it deactivates the cruise control, ABS System, traction control, and parking detection system. The dealer is able to verify the issue. I have taken the truck to the dealer, who is reporting a part shortage and multi-month backorder for the part. This is a huge safety issue, and could have killed me and my children. This should become an immediate recall since it directly impacts the safety features of the vehicle as well as the cruise control system, which may suddenly deactivate and cause sudden deceleration. Various warning lamps display. BRAKE, ABS, Traction CONTROL.
