Page 32 of 79: complaints 911 to 940 of 2,349, newest first, as owners wrote them.
ABS lights flash on and off while driving constantly. Affects concentration and cruise control. Radio will randomly start pressing all over the screen changing settings and distracting the driver.
Antilock brake warning light/chime and traction control warning light/chime keep going on and off causing the vehicle to have no antilock capabilities and disengaging the cruise control.
Abs system failed and had to brake hard causing the wheels to lock up and lose control of the truck ,lost speedometer, brake lights, 4x4,cc,trailer brakes
My 2018 Ram 2500 has 85,000 miles currently. At about 80,000 miles I got the ABS and Traction control warning lights along with dash messages to check the ABS amd electronic braking systems. I am a heavy equipment mechanic and thus checked the systems myself with a scan tool and other test equipment. I found that the ABS module has an internal electrical failure resulting in power not being supplied to the ABS pump/electric motor. I have verified that the pump works and has about a 48ohm resistance. If supplied with 12v and ground to the motor it will come on. Circuit testing from the electrical plug to the contacts for the motor one pin has contact and the other is an open circuit. I also have one seized plunger in the hydraulic control unit that is actuator by the motors eccentric lobe on the output shaft. After doing some research online I've found this is a very common issue on the 2017 and 2018 Ram heavy duty trucks, the 2500 and 3500 model specifically. I also found that neither the hydraulic control unit nor the ABS module have been available for purchase for a long time. I myself have been trying to order one for about 6 months. No dealer in my area can even give me an estimate time of availability. So currently I and many other have to drive a vehicle with a failed ABS system. This poses a greater risk of collision and unsafe braking. It is also a requirement to be working to pass a vehicle inspection so selling the vehicle or depending on state lived in you may not even be able to drive the vehicle at all.
Several systems suddenly were disabled, ABS, Electronic Stability Control, Front & Rear Park sensors, Tire Monitor system as well as the cruise control that may not be considered safety. The truck only as 11K miles. I have not been able to reset the system and the noted systems are inactive. I will contact the dealership but am bracing for a less than supportive meeting. From what I've read this is a very common failure on this year and model truck
General electrical failure of abs pump motor control. Intermittent issue causes loss of traction control, stability control and abs functions.
ABS warning light and electronic braking light will randomly come on and chime, not sure if this is going to affect braking.
ABS and traction control warning lights coming in and out continuously while vehicle is on. Usually the lights will lock in after a while and then the ABS and Traction control will not function correctly. It is widespread with certain years of this vehicle and Ram refuses to admit a chronic problem.
Abs and traction disabled randomly while driving.
July 11, 2024 Message alert appeared indash with instructions to service ABS system. This vehicle experienced the exact same issue in April of 2022 and was taken to the dealer(Patterson Dodge-Tyler,TX) for repair, where the ABS Module was replaced. The replacement was not covered by the warranty.
The contact owns a 2018 Ram 2500. The contact stated while driving 30 MPH, the ABS and traction control warning lights illuminated. The vehicle was able to be restarted; however, the failure recurred. The dealer was contacted; however, the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 130,000. The VIN was not available.
My ABS system has started going off and on intermittently but regularly. It turns my cruise control off and creates a hazardous situation with both traveling on interstate and when raining as I have no ABS.
Vehicles anti-lock brake, traction control systems become inoperable. Automaker is aware of the HCU and ABS defect, they have failed to recall affected vehicles or offer another remedy. Braking becomes much more difficult and a ram pickup becomes tougher to control without these systems, especially in dangerous road conditions caused by rain.
ABS light come on and the service antilock brake system light comes on and NO cruise control, happening all the time so NO ABS systems and in south dakota that is a big problem and no parts for 8 months now comes on when you hit a bump all the time 68 times driving 50 miles
The service electronic brake system warning light and chime along with the traction control and ABS warning lights and the cruise control fails to work. This occurs frequently. The code is C0020-01 ABS (Anti-lock Braking System) Pump Motor ControlGeneral Electrical Failure I believe.
Truck will flash warnings and dinging indicating that the anti-lock brakes and traction control has failed. Sometimes it'll stay that way and other times it will cycle multiple times. Like 20 times in a minute where the ABS and TCS are kicking on and off. Dangerous to have the brakes work like they're supposed to at random. It did this before in July of 2021, Scott Wood Dealership in Arkansas replaced the abs module/hcu. It is now doing it again, same symptoms.
ABS hydraulic pump failure, confirmed by Ram dealer. ABS light coming on and off affecting cruise control. Warning on dash says service ABS system. Truck only has 14350 miles No brake failures as of yet
My ABS light sporadically comes on and off. Dealership says it is the HCU module. It was replaced under warranty in 2020 and now has failed again. Wanting to file report so it is noted to help with initiating a recall on this failing part. I have read that the ABS module has also had similars issues with no recall as of to date either.
Day after purchasing my used 2018 ram the abs light and traction control started dinging continuously. Brought back to dealer they say there is no fix at this time. Abs control module and hcu need changed/repair but there are no parts available for fix. So now I have to pay/drive for truck that brake system /traction control does not work properly. Please do a recall on the and make them fix!! There are so many specifically 2018 ram models that have this issue. When you could purchase the part it was $1000 fix and no guarantee how long it would last. I believe dealer knew this issue and cleared code before I arrived.
Vehicle is currently displaying ABS warning light. Current mileage is 45,327. Dealership previously replaced Hydraulic Control Unit (HCU) at 4,002 miles. ABS Module was not replaced as part was on back order. Dealer noted usual procedure is to replace HCU and ABS Module. Dealer noted code C0020-01 ABS Pump Motor Control - General Electrical Failure. At 24,923 miles, vehicle again displayed ABS Warning. Dealer found Code C0020-10 General ABS Pump Electrical Failure. Dealer replaced HCU. Dealer noted ABS warning is serious and vehicle should be repaired immediately. The safety of my family has been put at risk on multiple occasions. Problem has been confirmed and acknowledged by dealer. Problem has not been investigated by others.
service abs system message and abs light and brake light coming on.. had checked and C0020-01 code for ABS pump motor control- general electrical failure
My ABS system went out while under warranty. A couple years later now I'm getting ABS module warnings. Brakes are different and the cruise control is affected at times. Sounds like very common issue to certain Ram owners. We need a recall.
ABS and ECS warning indicators are continually coming on and going off. I have read many complaints on Ram forums that are identical to mine.
HCU failed today 07/08/24. Service Electronic Brake System light comes on and off, traction control/abs malfunction indicator lights comes on and off constantly. Kicked cruise control off while traveling highway speeds causing a rapid deceleration to occur. Can't get in to dealership until July 17 to have it looked at. No other indicators/malfunction lights/codes came on prior to 07/08/24.
Twice while going up a hill in the rain I was changing lanes and the cruise cut out causing the vehicle to slow down rapidly and kick out in the back. The cruise abruptly stops when the “service electronic braking system” and “service abs” lights and dinging come on. Apparently this also stops the traction control from working. Looking on the internet and forums, this is a very common issue. In fact, there is safety recalls on later model Rams with the same issue on the same parts. Why not the models that this started with?
Everytime I press the brake pedal I am now receiving a "service electronic braking system." It is not every so often. It is every single time I press it. I have started researching this and there are thousands of other owners having the same problem that own the same truck as I do. They are also saying that every dealership either turns them away because they can't find the problem or they are giving conflicting reasons why it's happening and/or the part they say is the problem is on a massive, estensive backorder that could be months that sometimes fixes the problem for only a few months and have spent $1500 to $2500 depending on the location. They are also saying to report it to the federal safety agency to make Ram fix the problem since it is so widespread across the nation.
C0020--01 ABS PUMP MOTOR CONTROL - GENERAL ELECTRIC FAILURE. Available for inspection. Safety of self and others is at risk in ABS brake failure. Independent service center has confirmed problem. Vehicle/component has not been inspected by mfg, police, insurance, or others (besides independent service center). Intermittent warning lamps and chimes began in June, 2024, approx 65k miles on the vehicle. My understanding is that this is a common issue, faulty component and also involves the Hydraulic Control Unit ("HCU"). These are expensive components and labor. Expense for repair/replacement should be covered by manufacturer.
The truck's warning lights indicate ABS module, HCU module, and cruise control failure. The trailer brake controller, ASB system, and cruise control does not function. The truck's warning lights and chime have been going on and off for over 2 years.
The trucks warning lights indicated the ASB module, HCU module, and cruise control failed. The trailer brake controller, ABS system, and cruise control fail to function properly. The warning lamps and buzzer have been constantly going on and off for the last two years.
