Abs light service system
Abs light on repaired under warranty once now back on again truck only has 20000 miles but out of warranty light has been on for about 3 months dealer said no parts till 2024 dodge is changing the parts to fix this is what they are saying so they new original parts replaced with new but same parts was not fixing problem they should issue a recall it is totally their fault
The service ABS braking system warning flashes on with a chime frequently when driving. This started 3 weeks ago. According to the Ram Forums this is a common problem with 2018 trucks. My truck is a 2018 with 352623 miles on it and according to the Dick Hannah dealership a part that is out of warranty. There is no replacement part since the original inventory was all pulled back from the dealerships to the manufacturer due to the incidences of failure. This information was given to me by the Dick Hannah parts manager. He said a newer more reliable version of the brake module is being built but replacements are not expected for at least 4 months. Ram knows the part is and was defective, i am out of warranty and have a dangerous truck to drive for the next 4 to 5 months then a estimated $1500 repair bill. I want Ram to pay for this and to expedite the replacement parts and the federal safety agency to do their job and serve us the consumer instead of the manufacturer. I am seeking legal recourse too. I attached the repair code report derived from my Blue Driver code reader tool.
ABS warning light came on, this also shuts down the cruise control system. ABS traction control is inoperable, my understanding the problem is the ABS/HCU pump/Module.. I only have 9087 miles on this truck. It’s a Dodge 3500 Dully. I garage keep and baby this truck, as I paid a lot of money for it. It is my understanding, based on all the internet feedback, that this is a major safety issue and the federal safety agency is dragging there feet, on ordering a recall.
ABS Pump motor control - General electrical failure that causes the warning lights on the dash to illuminate and an audible chime. Occurring sometimes several times in a row, which distracts operator from safe operation of the vehicle with flashing dash warning lights and audible chimes, affecting in the operation of ABS SYSTEM if required for safe emergency stopping in an emergency situation. Yes the problem has been diagnosed by a dealer ECU: ABS, CODE: C0020-01, DESC: ABS Pump Motor Control- General Electrical Failure The Manufacturer has and is aware of the batch of failed components as per various website forums. And dealer says the components for repair are unavailable for sometime. Uncertain exactly when warning lights started to flash generally, October 2022
ABS and Traction control lights on. ABS Code C0020-01 ABS pump motor general electrical failure. See you recently posted some information regarding 2017-18 Ram 2500 -3500 trucks. Lots of complaints on Ram Truck forums. Lots of problems with HCU and ABS Contollers. SHOULD BE A RECALL. No braking problems...(yet)
HCU module failed. ABS module failed.
ABS System flashes on and off that it needs to be serviced, also cruis control doesn’t work. Took it to dealer to get it diagnosed. Dealer says the HCU needs to be replaced and the ABS pump needs to be replaced and also that cause the brakes and rotors to wear out and they need to be replaced too.
The contact owns a 2018 Ram 3500. The contact stated while driving 65 MPH with the Forward Collision Avoidance: Adaptive Cruise Control activated, the traction control and ABS warning lights illuminated intermittently. Additionally, the cruise control then deactivated independently. The contact took the vehicle to the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 161,000.
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.
Vehicle is presently throw an error for ABS HCU failures. There is not presently a recall but it is effecting all 2017-2018 RAM 2500-3500s. My has occurred and dealer confirmed but parts are not available for fixing. Vehicle is not safe to perform daily functions it was purchased for such as towing.
On my 2018 RAM 3500 beginning on Memorial Day 2023, the instrument cluster began flashing with a loud door type chime. The cluster began cycling through messages including Service Electronic Braking System, ABS Failure, and illuminating alarms. Upon testing with a code reader I was presented with the following codes: C0020-01 ABS Pump Motor Control - General Electrical Failure and U0402-00 Implausible Data Received from TCM. Upon internet investigation, I discovered this is not an uncommon problem with several hundred reports available on ramforumz.com and other sites. According to several complainants, the repair for this will cost in excess of $2000 with one complainant stating this has had to be repaired twice as the replacement components are also faulty. This needs to be investigated and frankly needs to be a national recall on these vehicles, it is a lot more dangerous than a tailgate lock issue. I am concerned with the cost, but more concerned that replacing the noted components may not solve the issue in the long term resulting in additional costly repairs.
The contact owns a 2018 Ram 3500. The contact stated that on several occasions while driving at high speeds, the vehicle drove over a bump in the roadway and the ABS warning light, electronic stability control warning light, and the check engine warning light intermittently illuminated but remained illuminated. The contact stated that prior to driving over the bump, the cruise control operated as designed; however, after driving over the bump, the cruise control failed to operate as needed. The vehicle was taken to Auto Zone for diagnostic testing. The contact stated that several unknown codes were retrieved. The vehicle was not repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 112,000.
The ABS/HCU module failed. I had to replace on 05/14/2021. At the time of replacement, I was unaware the federal safety agency launched an investigation October of 2022. At this present moment, I am faced with replacing the ABS/HCU module again. The cruise control does not work and the traction and ABS lights are on again.
ABS and traction control lights flash and ding on and off. Trouble shot it at dealership and wires were repaired hoping that would take care of it…. Nope, lights and dinging are back on. I tow a large gooseneck horse trailer up and down steep hills with sharp curves, across many state lines. We have the truck full of young children ready to show their horses - hence we have the crew cab. I’ll be towing within the month. I figure it must not be a safety issue - Parts are on back order until August??? We only have 40,000 miles on the truck. I can do without cruise control, but would like a safe braking vehicle - glad my husband got a stick shift to help control speed.
The ABS system activates intermittently, causing random braking or unable to break. Took to the RAM dealership to be told the ABS hydraulic control unit 68143491AB needs to be replaced but it is on back order until August.
NOTE: 11/18/22 filed a complaint with the federal safety agency - they will share it with manufacturer case number(ODI) - 11494143 QUESTION: What component or system failed or malfunctioned, and is it available for inspection upon request? ANSWER: ABS module problem Code : c0020-01 service electronic brake system Service Antilock brake system The display indicators for all of these systems come on intermittently. They effect the use of the cruise control as well. QUESTION: How was your safety or the safety of others put at risk? ANSWER: There is always the potential that any or all of these systems can fail at any moment when I am on the road driving; especially with 18k-20k pounds of load behind me. QUESTION: Has the problem been reproduced or confirmed by a dealer or independent service center? ANSWER: Yes. Galleria Tire Center in Pelham, Al. confirmed the display of all these warnings and also provide me with the code that I posted above on first question. QUESTION: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ANSWER: NO QUESTION: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? ANSWER: warning lamps come on intermittently and stay of for random times. Always wondering if one of the systems are going to fail. We pull an 18k RV with this truck and it would be tragic if we have a system failure that results in an accident. Online posts also verify that many other RAM owners are experiencing the same problem with their trucks. This most certainly needs to have a recall on it. Very dangerous. Manufacturer has great liability and litigation exposure if they do not act on this and accidents happen. They have been warned.
Hydraulic Control Unit failure on the automatic braking system. C0020-01 ABS pump motor control general electrical failure Failed at 38,000 miles I've contacted many dealers to find that parts are not available ABS and traction control light on all the time now
No incident as of now but brakes are spongy and ABS TRACTION CONTROL LIGHT IS COMING ON AND OFF bad HCU ABS MODULE.
ABS Module Failure, This has been a re-occurring issue that nearly caused an accident. The abs and traction control lights come on intermittently and disables the ABS/traction control emergency braking system. The issue has existed for 2 months, the dealer tells me it needs a new control module which is not available till some time in 2023. There advise was watch my following distance and maintain lower speeds. Unfortunately yesterday the light came on and stayed on for 50 miles plus, due to an accident on the highway all traffic had to stop quickly, when i applied heavy braking my wheels locked up and the truck started to slide sideways, i was able manually get control by fluffing the brakes but had i panicked i would have had a collision. when i got the truck to a full stop i was inches from a small compact car. There's no way to fix this and its going to cost lives for this very widespread issue with the dodge ram 1 ton pick ups, where's the recall does this need to kill a few hundred or a few thousand people before its addressed.

I was driving at highway speeds when the abs / traction control light came on. Notice cruise control was inoperative. The next day the warning lights were off. On the way home from work the system quit functioning again. After diagnosing found codes C0020-01 & U0403-00. ABS control module failure. I was told by the dealer this safety issue was not covered under warranty.
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.
ABS and Traction control pump system electrical failure. Went to a Dodge Dealer and had the system read due to light coming on and off. Originally started around 38,000 miles on the truck. A code came up C0020-01. ABS pump motor control electrical failure. Researched on the net. Seems to be a big issue from 2013 on up on trucks. Chaffing wires? Pump failure? Dealer said the ABS Pump could Possibly be bad. Wondering if there is a safety Recall or will have one. I have my truck scheduled for repair next week. Estimated cost of $700.00 according to service department.
Death wobble while driving down interstate going around 50/60 MPH. I hit a bump in the road as I was traveling onto a bridge and truck started shaking 'dangerously' out of control. The truck didn't stop shaking until I slowed down to around 30 MPH. It was hard to hold truck into highway lanes and I almost hit the guard rail on my right. The truck shook for at least 5 to 10 seconds and after getting back control of vehicle it did the same thing seconds later. This is very dangerous could have caused accident and loss of life!
