2018 RAM 2500 Electrical System Problems

Braking failed on vehicle, manufacturer refuses to provide repairs parts nationwide on all Ram 1500,2500,3500 trucks

Hydralic control unit is bad causing on dash safety alert for service electronic brake system alert and anti lock brake system alert. When towing will not have brakes to assist in stopping tow vehicle. The alarm constantly going off distract your attention from the road. Upon going to the dealer for repairs I was told they are on national back order and may not be available until after the 1st of the year. It apparently a widespread issue with all 2017 and 2018 Ram 2500s. I am unable to tow my 38' 5th wheel camper for fear I will lose my brakes on the tow vehicle putting myself and others at risk. The anti lock brakes not functioning properly could result in losing control of the vehicle when road conditions are wet or slippery. This loss of traction put me and other motorist at risk. Ram know there is a...

The ABS and traction control indicator lights come on and off intermittently. This is a huge safety concern has the ABS and traction control may malfunction. This issue has been brought to the dealer and they replaced parts less than two years ago. It has reoccurred less than two years later.

Abs traction control light has been going on and off since truck has had 15000 miles dealer replaced abs pump still has issues light is intermittent when it comes on cruise control shuts off truck now has 53921 miles on it and the dealership doesn’t know why light goes on and off

2018 Ram Sept 23, 2020 at 15,000 miles ABS light flashed on. Code said pump electrical failure. Dealer replace under warranty. Oct 12, 2023 at 50,900 miles, service ABS notice flashes on screen. Dealer confirmed ABS failure but said parts were on indefinite back order. Said last one took over a year to get parts in.

Intermittent warnings of ABS system needing maintenance while driving. No known cause or correlation to type of road/weather conditions. Intermittent ABS failure affects ability to use cruise control. This started when the truck was at 52k miles. This has been happening for over a year now and we have been told that there is an indefinite timeframe for repair due to massive back orders.

ABS service light coming on, and service electronic brake system keeps coming on. Recall on 2019-2022 RAMS for same issue. Told to report issue here.

The ABS and traction control systems on our 2018 2500 RAM truck are failing randomly, and the warning lights are coming on. The cruise control system is also randomly failing. Therefore, as we drive the vehicle and using cruise control the vehicle will randomly turn off the system causing safety concerns. The braking system and traction safety systems are not working properly and safely. The cruise control issues have been occurring for about 2 to 3 months. Over the last 1 to 1.5 months the ABS and traction control systems have started randomly failing and turning on the warnings lights and bell. We took the vehicle in for service today at the RAM dealer and was informed that the parts are backordered and unknown when any parts would be available. The dealer confirmed the systems are not functioning properly and provided written estimates and summaries of their findings. The dealer...

Anti Lock brake system and service electronic brake system message keeps going on & off every 30 seconds & will shut down cruise control if it is engaged. Happened in 10/11/2021 & now 10/8/ 2023.

My truck has the same issue as many thousands of other RAM owners. The forums are full of people with the same issue. It clearly is a faulty part/design or similar. My "check ABS/ Traction Control- Brake light" turns on and off intermediately all the time. It is an issue many have had and had fixed for between $800-1,000.00. For your reference here are some links to forums showing this issue in fact a OEM problem. Apparently there are class action law suits going on in Texas and California over this matter. [XXX] [XXX] [XXX] There are many more. RAM should have to furnish a recall and fix this issue at no cost. Parts are not available until February of 2024. This is a safety concern!! This issue will not allow the use of cruise control or remote start. Winter is coming and im not sure the ABS works as...

the abs module and the hydraulic pump have a issue that turns on the abs and light and turns off the cruise control and reverts to non abs braking due to faulty module and pump assembly that was changed already and now the wont cover this under any warrenty known faulty part

Intermittent ABS light and Service Electronic Braking System lights coming on and off. Appears from previous reports this is a known issue that has been going on for years now with this vehicle and should be fixed. I purchased a new hydraulic and electronic module from dealer at around 35000 miles and replaced. Issue was fixed or so I thought, at around 70000 miles lights are intermittently on and off again. No known issue was contacting ram direct, dealer I bought vehicle from stated the electronic module is backordered and has already been replaced with another part number, I believe it was a faulty replacement from the get go. Hydraulic module was said to be under engineered testing again per the dealer. Extremely frustrating from the customer end, no cruise, no abs braking capabilities. No known deaths to this point linked to this specific issue to my knowledge but I...

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 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 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

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.

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.

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.

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.”

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.

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

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.

I have a 2018 Ram 2500 - 6.7 Cummins diesel, The service ABS system and service electronic brake system dash lights come on and go off constantly. Every time they come on there is an alarm that goes off, and it also kicks the cruise control out. This problem started had around 32,000 miles and has continued to now 71,000 miles. I have tried multiple times to have this, diagnosed with a system reader with no luck. Have had the system reset also with no luck. I’ve read on multiple Dodge/Ram forums that this is an ongoing problem with 2017-18 and up Rams that they refuse to address. Any information would greatly be appreciated to get these problems resolved as it appears there are multitudes of people having the same issue. Thank You Note: The mileage on the pictures below is not when the problem started, these were a picture...

The ABS module is bad. Can not drive the vehicle for fear the brakes will fail, especially when pulling a trailer loaded with animals (farm). This is ridiculous, a $86K vehicle with less than 40K miles (we have not driven the truck in over a year) because of a faulty part that the company will not own up to. PLEASE have MOPAR/RAM/Chrylser own up to this faulty part and issue a recall ASAP. When the brakes lock up and someone dies, that will be a real issue. Sincere thanks,

ABS AND TRACTION CONTROL LIGHT ON. THIS IS A WELL KNOWN ISSUE WITH THE RAM 2500 YEARS 17-18. I PULL A TOY HAULER WITH 2 MOTORCYCLES IN IT. THIS IS A 28 FOOT TRAILER. I DID NOT NOT GET IN AN ACCIDENT BUT I HAVE NO TRACTION CONTROL OR ABS AT THIS MOMENT. TIRES WILL SPIN VERY EASILY IN THIS TRUCK IN THE RAIN. HAD THE BACK END STEP OUT LEAVING WORK CROSSING TRAFFIC AS I HAD NO ABS INTERVENTION AND IT WAS COMING OFF OF A BIG HILL. THE DEALER SHOULD BE COVERING THIS. I HAVE AN APPOINTMENT TO HAVE IT LOOKED AT AND WAS TOLD THE ABS UNITS ARE ON BACK ORDER TILL FEBRUARY WHICH MAKES PERFECT SINCE BECAUSE THEY ARE ALL FAILING. HOPEFULLY BY THE TIME I HAVE MY APPOINTMENT THIS WILL BE COVERED AFTER READING ABOUT THE LAWSUIT AGAINST THEM. APPARENTLY THEY RECALLED THE 19-22 VEHICLES...

The ABS light came on and went off intermittently, which also disabled the cruise control when the light was on. Eventually the light stayed on. Most recently the start button quit working properly. We have had it at the dealership twice with no results. We have talked to the dealership many times and been getting the run around. The latest was today and was told the parts are back ordered until 2024. They have not given us any paperwork because we do not have to pay. We also have and had the radio (main computer) replaced a couple of times and the screen still blinks randomly.

ABS/traction control sensor issue. I believe it to be a faulty sensor or sensor connection issue which is causing my service brake light to chime and light up at every bump in the road. While driving even just a short distance my service brake light/alert chime goes on and off sometimes every 2-3 seconds and while driving on the freeway my cruise control disengages every time the brake warning pops up. Upon researching this issue I've found thousands of Dodge Ram owners complaining of the exact same issues and dealerships are suggesting they know nothing about this problem.

ABS system failure, recirculation pump failure, code C0020, Ran off road while ABS and traction control was off during wet conditions. Unsafe to drive due to safety failure on ABS.

Lights on won’t go off

ABS module or HCU bad. Anti lock brakes not working. Cruise control not working. 4WD not working. Caused issue driving with a load when ABS did not engage and almost rear ended another vehicle.

C0020-01. Electronic Braking System and stability control system continually go in and out of alarm kicking the truck out of cruise control suddenly. This was repaired once under warranty by replacing the hydraulic control unit at 40,000 miles and it is now doing the same thing again at 90,000 miles. This is a significant safety issue as it prevents the use of cruise control and turns off the stability control system on the truck. The parts to repair the system are not available due to them being in “Engineering Review” until 2024. The only guidance from Ram was to continue driving the vehicle until parts become available.

SERVICE ELECTRONIC BRAKE SYSTEM NOTIFICATION TURNS ON INTERMITTENTLY, CRUISE CONTROL DOES NOT WORK DURING THIS TIME

ABS module

ABS warning light goes on and off at intermittent times. Message says service ABS brake system. This truck has not been inspected yet but there is a class action lawsuit and NHTSA investigation on-going for this problem.

Similar to the 2019 & newer Ram HD recall for the ABS electronic control module, my 2018 Ram 2500 has the same issue. It was recently diagnosed at the dealer in August 2023, but due to the abundance of impacted trucks, the dealer estimates that replacement parts will not be available until at least February 2024. While I wait for the repair I have no ABS, traction control, stability control, or cruise control. I drive the truck approximately 750 to 1,000 miles per week and have a 3,000 mile vacation planned in October. This translates to driving the truck approximately 15,000 to 20,000 miles without the above noted safety features. I believe my truck should be added to the recall, and RAM needs to step up and provide faster repairs.

In October 2012, my 2018 Ram 2500 had issues with the brake module and ABS system. The truck had 49000 miles when the system intermittently displayed messages to service ABS system. A trusted local mechanic checked and found a service bulletin about the issue. I had him replace the brake module and master cylinder. I then had a Chrysler dealer reprogram the module. My costs was approximately 800 dollars. Now it is summer of 2023 with 65000 miles and the same issue is occurring. I think it is time for Fiat Chrysler America to step up and make these repairs. It is dangerous to have this situation. It affects cruise control, four wheel drive, and of course negates having ABS. I need this truck and cannot afford to park it.

ABS TRACTION CONTROL BRAKING ISSUES AND DANGER. ONLY HAS 24K MILES GARAGE KEPT

My ABS and traction control dash lights came on and lost cruise control while towing my RV. I fear of someone rear ending me when loosing CC. The alerts intermittently go on and off.

ABS light and traction control light came on. Upon scan tool the code was general electrical failure of ABS system. I call my local ram dealer and they inform me of multiple failures of the HCU on 2017 and 2018 ram trucks. This is a safety hazard for my self, my family, and others. Theis desperately needs to be a recall on the ram trucks. This is very dangerous. Also the ram dealer talks of at least a 6 month lead time for this part.

I purchased the subject vehicle in NEW condition in September 2019. On April 2021 the vehicle ABS lights came on and off. The mileage of the vehicle at that time was 16,538. I took the vehicle in to get serviced by ANCIRA Chrysler Jeep Dodge Ram dealership and the HCU PUMP was replaced. I have the service invoice that has all this information. On August 20, 2023, the same lights came on. The vehicle now has 48,000 miles on it. As a part time mechanic, I conducted a diagnostic test and found that the error code is the same as the initial incident, which is Code C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRIC FAILURE. The vehicle no longer as a warranty and since there are no available parts available for repair, I have no choice but to drive this truck putting myself and my family in danger. The vehicle is...

ABS traction control, light code c0034

The abs module and abs pump has failed for a second time. Anti lock brakes do not work or traction control with lights on in dash The message appeared 2 years ago. Bought the parts and dealer fixed it. Now the message is coming up again.

My ABS and Traction control lights activated visually and with audible alarms. I brought it to the dealer. It only has 23,000 miles on it with a manufacturer extended warranty. The dealer told me that the ABS pump motor control as well as the HCU has failed and need to be replaced. They also told me that the parts are not going to be available until the EARLIEST February of 2024. The vehicle is not safe to drive without these safety systems working especially towing. They told me the parts are under Engineering review. They suggested I park the vehicle until parts are available. NOT ACCEPTABLE!!! I have looked at owner forums and this issue is common and needs to be addressed by NHTSA and the vehicles recalled due to safety.

Service ABS system and traction control light continually flashes on and off. Does not allow me to use cruise control and it also turns off my ABS which is unsafe.

My vehicle keeps throwing up a service ABS and service electronic braking system intermittently and the braking system is greatly diminished. Vehicle has been inspected and the replacement parts for the breaking system are on national back order without a recall open.

My ABS / Electronic Stability control warning lights keep coming on intermittently and also sometimes staying on for hours at a time. I cannot use my cruise and my ABS will not work with these problems making this a very dangerous truck to drive. I have read that there are many other trucks with this issue. More specficially the 2017-2018 Ram 2500's. I believe there should be a recall for these parts as this is a intergral function in these HD trucks.

Abs HCU failure. This is a know common issue and yet no recall. THIS IS NOT SAFE
