2018 Ram 2500 complaints

ABS pump fault C0020-01

Abs module. Antilock brake system failure. Known issue by manufacturer.

Antilock braking systems does not work

I’ve just started experiencing the ABS light coming off and on. Did some research and find that this is a common problem wish my truck. Making appointment with dealer to have it checked out. Also about a year ago my radio had to be replaced as the screen was delaminating. Was told this also common problem but Ram was of no help. Had to buy new radio. Now my truck only has 32,000 miles on it and was under 30 when radio was replaced. But I’m second owner and ram would not warranty it. Now that I’m researching this site I’m seeing many problems that are consistent with mine. This should be a recall. The brakes and the radios. Think I’ll be trading this truck off.

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.

Abs traction control light is on again this is the second time this has happened dealer replaced abs module lasted a little over two years now problem has started again.

ABS constantly fails. Check ABS and traction control fail light constantly appearing. Suspected ABS module failure.

2018 Ram 2500. Trouble code for service electronic brake system, traction control deactivation, cruise control deactivation, ABS deactivation occurs at all speeds and all surfaces intermittently and the trouble code will activate and deactivate for up to approximately 45 minutes continuously . Ram certified dealership service departments in 2 states have declared it a known issue, have stated there is a TSB for repair but parts are unavailable with no ETA. Vehicle is under warranty but no remedy except to wait for parts which I have done for almost 1 year. Several other colleagues have the same issue which makes me concerned that probably 1 in every 3 2018 Ram 2500s are or will become safety concerns. It would be my intention to sell this unsafe vehicle as it is a primary means of transportation for my school aged children but no dealership will entertain a trade or severally reduces the trade in amount due to an issue that I can’t even through a factory warranty still being active have resolved. I have no other recourse at this time other than to advocate for individuals to sign up for the class action lawsuit against FCA which covers this exact issue which will hopefully force FCA to fix these unsafe vehicles before deaths or serious injury occur. Any help your organization could be would be appreciated as this is a glaring safety issue known by the manufacturer and these vehicles are used for towing.

Defective Brake Control Module and Hydraulic Control Unit intermittently cause ABS and Traction Control warning lights and error messages to repair ABS and Electronic Brake System. This causes cruise control to drop and no ABS braking. This first happened 2 years ago and was dealer repaired and now it's happening again. This is obviously caused due to defective parts.

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

Abs system fail off and on which disengages the cruise control.

ABS module failure, brakes can potentially lock up causing you to slide. Preoblem has been verified , but has not need inspected by manufacturer (on my vehicle). And there were no symptoms, light came on as soon as it failed

I have the warning light that comes on and message stating to " Service Antilock Brake System" and " Service Electronic Braking System". I have spoken to 2 different dealerships, and both tell me that it is an issue with the ABS Hydraulic Control Unit. Both dealerships tell me that no replacement parts can be ordered and there is nothing that can be done to fix problem. The vehicle has less than 50,000 miles and the brakes do not work as they should. This is a major safety issue, and I am being told there is nothing that can be done about it.

I keep getting alarms on my truck for the ABS system and brake controlling system. I took the vehicle to a dealer to find out the problem and was told the HCU and the ABS module both need to be replaced and this is a common issue with my year and model truck. I was informed my repair bill would be over $1900. I tow a fifth wheel camper on a regular basis and do not want to have my brakes lock up while an 11,000 pound trailer is behind me.

I have had problems with the ABS lights and warning come on 4 times. 2 times I have had it repaired by Philips Dodge Ram in Ocala Florida. I had it repaired at my own expense at Hilton Automotive and once under warranty at Hilton Automotive. My truck only has 12145 miles on it. The lights are still on and the warning flashes at times. It appears to have something to do with the temperature. After repairing it worked for a week or so until the temperature dropped under 75 at night. I cannot afford to spend over $1000 a month to keep this straight.

Electronic Braking System and Anti-Lock Braking System has intermittent failure and any speed. The safety of those in the vehicle are at risk by unsafe braking and unpredictable braking. Warning signals turn on and off while driving. Started to appear around 44,000 miles.

The ABS and Traction Control lights constantly come on, even after replacement HCU and ABS parts are replaced. It’s a once a year fix, and should be recalled. Once the lights come on, braking is affected, and cruise control no longer functions. I used a previous date, because I need to replace the parts again, for the third time. I have asked Ram support to just send me the parts, and I will do the repair, but unfortunately, they prefer that I continue to pay the dealer to repeat the same repair over and over.

My ABS and traction control light intermittently blinks on and off. I took my vehicle to the dealership and was told this is a known issue. That I need a new ABS power module and controller. The parts are very expensive and on back order. I was informed to continue driving the vehicle until the parts are available.

In July, I drove over a bridge expander bump and now I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit. The lights and notice come on then go off for a few minutes then back on again. This repeats until I turn the truck off and restart it. It then stopped for several months, but is now doing it again yesterday after driving over a very small bump in the road. My vehicle is available for inspection upon request. This problem puts me and my family at risk because the anti-lock braking system and traction control are deactivated during these incidents. I am not able to reproduce the problem at will, it happens randomly and intermittently. The vehicle has not been inspected yet. On-line research indicates many owners are having to replace ABS sensor and pump around the same amount of mileage as mine.

The truck consistently flashes a warning for “Service Antilock Brake System” and a scanning tool provides the code C0020-01. The truck was evaluated at a local mechanic, who indicated the code represented a general ABS system failure. I have researched the issue and found that this problem is a common complaint with 2018 Ram 2500s.

Starting March of 2022 I began having intermittent alarms for the anti-lock brake system needing to be serviced. Often the alarm would come on and off going over small bumps in the road. With time the issue became worse and the alarm is on all the time. This affects the vehicles anti-lock brakes, electronic stability control, and the cruise control. I took my car to a mechanic and they found that both the hydraulic control unit and the anti-lock brake system module need to be replaced. Cost is over $2000, but feel I need to replace to have a safe vehicle as I often pull a trailer.

The ABS system is not working it has a C0020-01 code. Yes it is available for inspection 24 hour a day. The anti-lock system did not activate in slick rainy conditions. The problem has been confirmed by an independent service center. Messages- Service Electric braking system. Warning Lamps- ABS and traction control. Other symptoms- loss on cruise control. All of these symptoms started in July of 2023 with 80k miles on vehicle.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the brake pedal was depressed but the vehicle was slow to respond or stop. The ABS and traction control warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the hydraulic control unit needed to be replaced. The vehicle was repaired under the warranty, but the failure recurred. The service electronic stabili-trak message was displayed. The vehicle was taken to an independent mechanic; there was a hard code retrieved: COO2O-O1; related to the ABS pump motor control. The manufacturer was not contacted. The failure mileage was approximately 21,477.

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.

C0020-01 ABS Pump Motor Control Electrical Failure.

My ABS and traction control lights keep coming on intermittently with a message saying service electronic brake system and anti-lock braking system.

ABS light coming on and going off like all ram 2018

ABS code c0020-01 indication of module failure. This is the second module on the truck. Seems to be a major issue with these year trucks and back ordered parts for there past several.

Antilock brake light and traction control failed. Bad HCU

The contact owns a 2018 Ram 2500. The contact stated while driving at approximately 40 MPH, the ABS warning light illuminated with an audible chime. The contact stated that the failure had been intermittent but had become a recurring failure while driving at various speeds. The contact stated that when the ABS warning light illuminated with the cruise control engaged, the vehicle would revert to manual mode and turn off the cruise control. Additionally, the cruise control could not be re-engaged. The contact also stated that when the ABS warning light was illuminated, the brake pedal would feel soft or "mushy" while depressed. Additionally, the contact stated that while making a tight turn to either to the right or left, the steering wheel felt loose. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the ABS Control Module needed to be replaced. The steering wheel failure had not been diagnosed. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 110,000. The VIN was not available.

Light on dash came on ,brake pedal got so hard to push,almost could not stop.Had to leave truck parked for 2 months waiting for parts.Was told by Mopar parts the anti lock solenoid and control unit were a problem,and would probably fail again

At approximately 30,000 miles the vehicle warning lights for "Service ABS" and "Service Electronic Brake System" began flashing intermittently. I took it to the local dealer and they replaced the Hydraulic Control Unit (HCU) on 5/12/2021. Approximately 2 months ago the exact same warning lights began flashing again so we took it back to the dealer yesterday 9/28/2023, 53,000 miles, and they diagnosed it as being the HCU and recommended that we do not drive the vehicle. They want to charge me for the exact same repairs that happened 23,000 miles ago. This issue is known but yet they will not fix this vital safety component of the vehicle. I cannot believe that a recall has not been initiated for this safety hazard.

ABS/HCU modules have failed. A loss of ABS and braking power have been experienced. When towing, this creates a problem as it happens very suddenly and intermittently, placing myself and others at risk of loss of braking power. Warning lamps indicating ABS failure/electronic braking system service is needed come on only when braking, and is intermittent. There is no indication of a problem until brakes are applied.

I have approximately 86000 miles on my truck and today the Service Electronic Brake system warning starting coming on and off. Along with the ABS light and traction control light. Randomly flashing on and then off. Staying off most of the time. I did a search and apparently this is a huge issue with these trucks, a couple of electronic assemblies melting together and going out. This needs to be a recall that Ram pays for. What happens if my brakes go out?

ABS and Traction Control code warning lights appear intermittently on instrument panel stating “service electronic braking system” and “service ABS system.” These indicators flash consistently on the IP but do not stay constant currently. Failure of these systems could result in loss of control of the vehicle during emergency breaking by allowing the tires to lock up during breaking. Code has been verified by Champion Chrysler Jeep in Brighton Michigan as “ABS Pump Motor Control.”

Antilock Brake System and Traction Control intermittent warnings while driving. Affects ability to use cruise control and Tow / Haul capability. If in tow/haul mod ABS warning flashes will also get Check Engine Light warning.

Keep getting “service anti-locking brake system” and “service electronic brake system” that intermittently turns off and on. 2018 Ram 2500 6.4L with 81,000 miles. Appears to be a common issue but no recall has been made.

Recently the ABS Warning light and Service Electronic Braking System light have been coming on intermittently. When it happens an audible alarm goes off and several functions shut down, like the cruise control. The problem has no rhyme or reason and some days it happens for several hours and some days it never happens. I am concerned that the ABS is not working properly but also concerned that I might be using cruise control on the highway and it shuts down creating a hazard and possibly accident. I have not contacted the dealer but see that it is a common problem with my vehicle on online forums and that there are class action suits for the issue. This should be handled by the manufacturer with a recall before someone gets killed. Currently the dealers are making a fortune making repairs that often recur in a short period.

While driving ABS and traction control lights came on and cruise control would no longer function. This has occurred 3 times and had to be repaired 3 times. 10/10/2019, 07/20/2021,and 08/19/2023. The parts replaced: 68347098-AB Module AN 08035030, 68143491-AA Control A 08035030, 68143491-AA Control Anti-LO 080, 68143491-AB Control Anti-LO 080. The parts are not available for inspection. Also, brake fluid 4318080-AD was replaced or added each time. These parts were replaced by authorized Dodge Ram dealers, one in Michigan and twice by a local Dodge Ram dealer in Florida. No warning of problem and vehicle still functioned except for cruise control. Problem first occurred at 3,305 miles, then at 17,161 miles, then at 25,203 miles

I have a 2018 Dodge Ram 2500 pickup truck and my ABS engine light came on back in February 2023 indicating that I have a problem with my braking and traction control system. It was because of the Hydraulic Control Module was bad. I Contacted a Factory Chrysler Parts supplier to obtain a new part to have it replaced but they were on backorder until June. In June I contacted them again and was told they were on back order until October 2023. I just contacted them again 9/27/23 and now I am being told the part is on back order until February 2024. This will be a full year causing me to drive without the ABS or Traction control not working, as well as not having cruise control. Doing a search on the internet there are a lot of others having the same issue which is bad enough but when you can't even get the replacement part for over a year on a piece of safety equipment for your vehicle . This is more then a safety issue.

Failure of the HCU (Hydraulic Control Unit) and ABS module. Caused loss of ABS system, Electronics Stability Control system, Electronic braking system, cruise control. Messages appeared on dash. All associated warning lights illuminated. Dealer stated this is a known problem and parts have been on backorder.

I bought this truck new from the dealer. At 18,920 miles, the ABS service light came on and the dealer said the ABS module would need to be replaced. A new part was installed. At 49,715 miles the light came on again and the dealer says the module is defective and needs to be replaced again. This part is on back order for over 2 months telling me these items are in high demand. I don't believe that items like this should be defective and require replacement in this short interval.

ABS HCU/and pump failure. Truck dies. no Brakes

My 2018 Ram 2500 has an intermittent ABS/ Service Electronic Braking System light. If I am using the cruise control when this light, comes on the cruise control turns off and the vehicle slows in front of moving traffic. I seem to also loose traction control which is dangerous when towing heavy loads.

The "service electrical brake system" and "service abs system" lights / warnings have been intermittently going on and off. This also does not allow the cruise control to work. The alerts can range from once every couple of days to repeatedly going off non-stop during my drive. Issue started around Oct of 2022. Warnings will stop for several months then return.

Service ABS system/ Electronic break system warning light came the dash control. When that happened in September of 2020 I lost traction control and cruise control on my truck. Since this accrued I’ve had several near misses of accidents do to lose of ABS system. I have not had it looked at by the dealership due to the fact that two family members have the same truck with the exact problems. They took their trucks into dealer. The 2021 was fixed under warranty and the 2017 truck was repaired out of pocket to dealership.

The “Service Anti-Lock Braking System” warning turn on and off intermittently and the yellow “ABS” and “traction control off” icon turn on and off intermittently about every 4-5 seconds. In the morning after first start, the warning lights and message proceed after the first brake pedal application. I have 78,500 miles on the truck.
