I had an intermittent abs/traction control light that now stays on 90% of the time. Code C0020-01 for ABS general electrical failure.
2018 Ram 2500 brakes complaints
Page 43 of 79: complaints 1,241 to 1,270 of 2,349, newest first, as owners wrote them.
The ABS module failed. This resulted in the ABS function not working along with cruise control. This seems to be more common with this model year. Warrant did not cover this so I had to pay the dealer to replace the ABS pump and ABS electronic module .
Service anti lock braking system and electronic brake system code constantly coming on. This is an apparent safety issue that Dodge needs to resolve. After much research, I’ve discovered that there are many, many complaints of 2018 Ram truck owners having the same problems. Thanks for all your assistance.
Service Antilock Braking System and Service Electronic Brake System will begin to constantly flash on the dash. It would display the ABS light and the Traction Control light. At this time it would also turn off cruise control while traveling down the highway. I purchased the truck with 62,000 miles on it on 12/28/2023 and the issue occurred on the way home and ever since. Since I was not aware of this issue, the truck slowed down and I was almost hit. I had to pull off the road to figure out what was going on.
The ABS lights and traction control lights alarm keeps flashing on and off at random intervals) on my 2018 Ram 2500 4x4 with 18,000 miles on it. When the ABS Light and traction control light come on intermittently it also disengaged the cruise controls. At first it was here and there or when I hit a bump or turning the steering wheel right or left. Thought it was possibly a wheel speed sensor. Checked code with scanner and got “ABS pump motor control-general electrical failure”. Thought the issue was the ABS module based on my scan. I tried to find the part I had to call all over the place due to supply chain issues. When I spoke to a parts person from a dealership I explained the issue and code. He stated that the General Electric code failure was the HCU and not the ABS module. It’s bad when your cruising at the speed limit of 70 mile an you and the cruise control quits working an you ned to react to the traffic but, my real concern is that the ABS won't work and could cause the truck wheels to lock-up during a panic/hard stop.
ABS warning lights came on while driving, early October 2023. Dealer diagnosed problem as faulty pump control, faulty module. Lights continue to flash while operating vehicle, along with the cruise control being disabled. Dealer has pump control, module is unavailable, with no known date of availability. Therefore a repair has not been made and I have no choice but to continue driving the truck in unsafe condition.
ABS and traction control lights keep turning on and off. Truck currently has no ABS.
Electronic Braking system failure affecting the ABS system, Traction control, and cruise control. It puts the safety of everyone in the vehicle and on the road at risk because the ABS and cruise control will fail causing an unexpected adverse conditional that can lead to an accident. This is a known problem for RAM and their is no fix at this time other than making the customer pay out of pocket for the broken parts to be replaced with the same parts that will fail shortly after. There needs to be a recall and a permanent fix from RAM
ABS and traction control warning lights intermittently. Loss of cruise control. This appears to be a known problem with an expensive repair.
The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, the ABS and traction control warning lights activated along with an audible alarm. The contact stated that during the failure, the cruise control feature was inoperable. The cause of the failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 42,500.
ABS Service Required Light and alarm and Electronic Braking light and alarm are coming on and going off. Just started in the last week. Apparently this issue has existed since 2018 with no recall issued to date. ABS module has not been available and shows Discontinued. I have not been to the dealer at this point, but from research the problem is a bad ABS module from factory. Hundreds of other trucks are affected with no resolution. I have to tow a 38 ft trailer and it may be unsafe if ABS fails. I do NOT want to have an accident and destroy my truck and trailer and/or have my wife and I injured or worse. The vehicle is available for inspection. I would be certain that the threshold for complaints has been met. If you are serious about vehicle safety, you will put a recall on the affected vehicles and require the parts be made available for repair sooner than later. I have seen where people have waited several months and still have no parts. Also, the cost of repair out of warranty is somewhere between $1200 and $1700 . For a manufacturer defect this should not happen. Please issue a recall!
The abs module is not working and yhe braking is hard to use.
Abs dash light
My 2500 hydraulic control unit is causing light to constantly come on and go off causing cruise control and ABS lights. This is a rampant issue with the 17-18 year truck but no recall. The part is bad that cause the manufacturer to come out with a replacement part but still no recall and this is the second time it’s happened the first time it was under warranty. But not this time.
Brakes when depressed do not pull equal. No cruise control. 4 wheel drive is not working properly. Traction control not functioning properly Have brought vehicle to a garage. Abs/hcu unit is the problem.
The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the ABS and traction control warning lights illuminated on the instrument panel. The vehicle was taken to the dealer, who diagnosed failures with the ABS control module and hydraulic control module. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 48,000.
Service electronic brake systems, service anti-lock brakes. replaced under warranty and now the light comes on intermittently. Obvious problem with the Ram trucks
Coming down a ridge with a loaded hay trailer approximately 14500 pounds, the Service Electronic Braking System and Service Automatic Braking System messages appeared in the cluster EVIC display and the service brake and traction control warning lamps illuminated and there was associated chime. I applied the brake pedal and it went to the floor with zero affect. The trailer brakes didn't respond either. I used the exhaust brake and skillful downshifting (it has a manual transmission) to slow the vehicle and then used the foot applied emergency brake pedal to bring the truck to a stop. I was lucky I was already carefully descending off of the ridge and I was able to downshift and slow before engine RPM became an issue. I cycled the ignition and the warnings went away. I very carefully and very slowly completed my descent off the ridge. Now the warnings, light, and chime are incessantly coming in and then just as soon turning off. I don't trust the truck is fit for my purposes at this point in time. I hadn't been that scared since my dad and I lost a rear axle and brakes on our 1969 Ford F-250 with a load of wood in the back coming down a mountain road when I was 12.
I have a 2018 Ram 2500. Service anti-lock brakes message is intermittently coming on and off. This occurs every few seconds while driving the truck. I took the truck to a repair facility and was displaying a code for the ABS/hydraulic control unit. I learned that there is not a known replacement to solve the issue. I have connected with other Ram owners who are dealing with the same issue while replacing unit multiple times. Ram needs to address this issue, I and along with many others are driving with no anti-lock brakes.
I’m receiving two codes; Service Antilock Brake System and Service Electronic Braking System. I met with my mechanic this morning and he said that this is a very common problem with the 2018 Ram 2500. Since this is a reoccurring safety issue i feel that Dodge should resolve not the owner. Should I get in an accident from a break failure who is responsible?
Antilock braking and traction control system failed. I was driving on a snow/ice covered road and hit the brakes with no anti lock control and truck slid in road side ditch. Truck has not been repaired. This is a known problem that Dodge is well aware of. This could have caused serious injury or death under alternate driving situation or heavy traffic. Any help would be greatly appreciated.
ABS and Traction control has been lost and have created a safety risk especially during inclement weather. The ABS pump or the ABS control Module is faulty in multiple years Ram vehicles. I believe based on forums there is a recall issue with these parts.
ABS and Traction control lights keep going on and off, this still continues and it looks like Ram knows this is a safety issue. Dealers have no parts for repairs
On October 6th, 2023, my ABS and traction control light began to intermittently come on and turn off. Truck had about 60k miles on it at this time. Problem still persists now at 63k miles and seems to be getting worse. In 5 minutes of driving at freeway speeds, the lights come on and turn off about 20-30 times. I worry that my ABS system is not functioning properly and may result in an accident. Issue has been replicated by technicians at 4 Wheel Parts. Code reader is showing a C0020-01 code is stored in the computer.
I spent close to $1,700 to replace hydraulic control unit (HCU) at a local dealership on 4/7/2022 when my pickup truck was only 25,392 miles. Since the flashing of ABS/Traction Control lights did not stay on, I paid for the first diagnostics at this dealership but did not read the error code. I had to return couple times, and the service tech finally saw in person when the lights were flashing and was able to use the factory diagnostic scanner to read the error code, C0020-01. This error code directed the tech to replace hydraulic control unit (HCU). "...The replacement procedures says to drive vehicle if code comes back replaced abs module..." From online search, I found out that the replaced HCU in my truck was still XXXXXXXXAA, not XXXXXXXXAB, as shown on the invoice. Therefore, it explained that my truck now has the same ABS/Traction Control light flashing problem while driving or idling only after no more than 13,000 miles after the repair. So no cruise control could be used. I returned to the same dealership today, 1/15/2024. However, the service advisor warned me that I'd have to pay for the diagnostics ($296) that might not guarantee to find the error code since the flashing was not happening in front of the service advisor. I was told that until the flashing became permanent then return like last time. Based on this conversation, I felt that the dealership did not want to take any responsibility. My last paid repair at this dealership would only cover new part and labor for 24-months by the manufacturer, MOPAR, which is about to expire on 4/6/2024. I strongly recommend the federal safety agency to: 1) require MOPAR or the dealership to have free diagnostics, especially when customer provided video evidences the day before arriving at the dealership for help. 2) recall all ABS & HCU modules in 2018 Ram 2500 Diesel or gas. 3) require MOPAR to reimburse prior repairs nationally for all Ram owners experiencing the same problems prior to Nov 2022. Thank you very much
24700 miles is when the Warning lights and chimes started. I went on line and apparently this is a common problem with 2018 Ram Trucks. ABS Warning and "Service Electronic Braking System" Lights are on. Went to dealer (Wilson Jeep Chrysler Dodge Ram) they didn't even look at the Truck or hook it up to Diagnostic. They said it's the Hydraulic Control Unit . Parts are on National Back Order, they know about the problem and their shop as fixed over 60 trucks alone. *Manufacturer as not issued any recalls addressing this issue*
The ABS system is malfunctioning intermitantly. The vehicle can be available upon request. The safefty of any persons in the vehicle are at risk if ths brakes dont work properly. The problem has been diagnosed by an independant service center in Angola Indiana. There are warning lamps on for the ABS and a warning bell as well.
Vehicle's "Service Anti-Lock Brake System" light and warning tone is coming on intermittently. I researched this to a common problem with the Hydraulic Control Unit (failure), which is known by the dealer to be common problem among 2017-2018 Ram trucks. Problem with the original manufacturer of this unit, with no parts available for replacement at this time.
I own a 2018 Ram 2500 with 104,000 miles. During the period of ownership I have had to replace the ABS/traction control module twice. Each time the repair is over $1,000.00 to have a Ram dealer diagnose and repair my abs brakes. This is a very significant safety issue. Without the ABS system I cannot control this vehicle in an emergency stop situation. You cannot use cruise control. This ongoing issue needs to be investigated and Ram needs to be held accountable for a well known issue.
The HCU in which controls your ABS and Traction control will malfunction while driving down the road when this happens you have no ABS, traction control or cruise controls. The dealer part is unavailable through the dealer due them saying that they are reviewing it. This is a major safety concern due to the fact if you are traveling and it malfunctions and need to stop quickly you cannot or if it malfunctions and have cruise control set to a speed it will slow you down and can cause an accident. When vehicle was carried to dealer and asked what to do the dealer just said to drive it and don’t follow to close to anyone, that is not the answer that needs to be given.
