2018 Ram 2500 complaints

Vehicle showing error code C0020-01 which is an issue with the ABS system. This is a known issue among the 2018 Ram Trucks which after searching repair options seems to be happening more frequently than it should. This is a major safety issue that is effecting thousands of vehicles and should be addressed. Repairs require a replacement of the ABS Module and the HCU. The manufacturer should be required to fix this safety issue.

"Service Electronic Braking System" and "Service ABS System" lights are flashing intermittently and the "ABS" and "Traction Control" lights are on as well. No diminished braking has occurred yet, however the ABS and traction control become disabled when the issue is present. I am currently opening a STAR case with RAM and attempting to schedule a dealer appointment. The issue started at 43,500 miles. This problem appears to be widespread on 2018 RAM 2500/3500 trucks and represents a safety issue, as the braking and traction control mechanisms are disabled when the issue is present.

WHILE OPERATING VEHICLE THE ABS AND TRACTION CONTROL LIGHTS WOULD FLASH ON AND OFF AND MESSAGE SERVICE ANTI LOCK BRAKE SYSTEM. THEN SERVICE ELECTRIC BRAKE SYSTEM WOULD FLASH IN MESSAGE CENTER. AFTER FLASHING ON AND OFF MULTIPLE TIMES THE MESSAGES SELF CLEARED AND LIGHTS WENT OUT. EACH TIME HITTING A BUMP THE LIGHT WOULD COME BACK ON, THEN WHEN HIT ANOTHER BUMP LIGHT WOULD GO OUT.

The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the “Service Electronic Braking System" and the Traction Control icon were illuminated. During the failure the cruise control would independently be deactivated. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure but no assistance was offered. The failure mileage was 9,000. The consumer stated when the vehicle is started and placed into gear, "Service Electronic Braking System, Traction Control, and Anti Lock Icons" all illuminate. The manufacturer stated the vehicle is out of warranty and if fixed it will be at the owner's expense.

Service Electronic Braking System and Service ABS system lights are flashing intermittently and the ABS and traction control lights are on. Dealer has indicated the hydraulic control unit is bad and needs replaced but they no longer manufacture that part and there are no aftermarket offerings so vehicle cannot be repaired until parts are located. In the meantime these vehicles affected have no anti-lock brakes and the cruise control randomly shuts off if the ABS light flashes while cruise is enabled.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, the ABS warning light flashed off and on. The contact indicated that when the failure occurred with the cruise control activated, the cruise control feature independently deactivated, causing the vehicle to decelerate. The vehicle was taken to the local dealer who diagnosed that the ABS pump motor control unit was faulty and needed to be replaced; however, the part needed to repair the vehicle was on backorder. The vehicle was not yet repaired. The manufacturer was not yet notified of the failure. The failure mileage was 65,000.

ABS hydraulic assembly fails intermittently and randomly during driving causing the warning chime to sound repeatedly and results in distracted driving as well as degraded braking safety feature.

ABS Hydraulic Control Unit and Electronic Control Unit Failure. ABS MIL and Traction MIL began turning ON and OFF intermittently during daily driving, sometimes turning ON and OFF over 50 times during a 20-mile drive. Lights up the dash and sounds a beep to inform the driver, while displaying a message on the dashboard screen. Again, this occurs every time the alarm activates. No dealership was able to get me in for an appointment when the issue first began. Took into the dealership today for diagnosis. The technician immediately knew the problem when I said the ABS light was blinking randomly and noted that he has seen this with all 2018 RAM 2500s. The first safety issue is regarding the loss of situational awareness while driving caused by distracting alarm systems. The second safety issue is that ABS WILL NOT work if the alarm is active, effectively setting up the driver to be placed into a dangerous situation during inclement weather conditions where ABS might mean life or death during a hard braking situation. The ABS system is only covered under a basic warranty with Dodge (3yr or 36K). The ABS system failed around 36K, but due to dealership waitlists, I was not able to be seen until 41K. The cost for total ABS HCU and control unit replacement is around $1500.

ABS hydraulic control unit failure causing ABS system to deactivate.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the service ABS and service brake warning lights illuminated. The contact also stated that the speedometer failed and became inoperable. The contact was concerned for his safety while driving the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS module needed to be replaced. The vehicle was not repaired. Neither the dealer nor the manufacturer was not notified of the failure. The failure mileage was approximately 38,000.

39,125 miles - 2018 RAM 2500 6.4L (purchased new in 2019), intermittent ABS / traction control light and alarm dinging! Dealership diagnosed it as the ABS / hydraulic control unit with code C0020-07. Many reports of this same issue can be found online from RAM owners having this exact issue, most are just out of the warranty. Low or backorder status of the replacement parts also suggests an issue. ABS function and cruise control are disabled when the error occurs and no way to know when or how long the issue and alarm dinging will last. This is a major safety problem that should be a recall.

ABS and Traction Control warning light keeps intermittently coming on and then a message saying that the Electric Brake system needs serviced. This has happened to my 2018 RAM at 17,000 miles. Dealer replaced ABS module under warranty and problem was solved. Now I am at 35,000 miles and the problem is back. Same exact issue. This needs to be a recall item ASAP and this seems to be a VERY common problem with these trucks. This could be very dangerous as these trucks are made for towing heavy loads and losing your anti-lock braking capabilities could be catastrophic to you or anyone else on the road.

The truck recently started displaying "Service Antilock Brake System" periodically on the information panel. Sometimes it comes on periodically while driving, sometimes only once, sometimes every minute or so and sometimes does not come on at all. We have not had this inspected but looking online appears to be a common problem in these trucks that should be considered a recall. Truck only has 50K miles when this started but this appears to start as soon as 3K miles on some other trucks. This should be a recall as the ABS system is a safety feature that should not be malfunctioning. A second issue that started shortly before this one is the steering wheel shakes when making turns and going over bumps. The truck was serviced for the drag link recall and this started shortly after that and is getting worse with time. Not sure if related to the ABS problem since they started pretty close together or if this is related to the 4WD as it shakes when turning similar to when the 4WD is selected but in this case it is not. This is also a safety issue as you could lose steering.

Vehicle has 21000 miles currently. Service ABS warning and anti skid disabled warning are intermittently flashing on cluster repeatedly. Brakes do appear to work but ABS is not I believe based on towing a heavy loaded trailer when coming to a quick stop in the rain on an irregular surface. Luckily the trailer has dual axle electric brakes and I was able to come to a stop safely. I have pulled the DTC code which is C002001 and states general electrical failure. Found reported Star case [XXX] in NHTSA website that was written in 2020. Have not been able to get into a dealer for service and they appear booked out to early to mid October. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Electrical issue with the radio. It will change screen, turn the radio up and down. Turn and off. Makes SOS calls on its on. Turn the AC to hot in Arizona when it's already 100+ degrees out. All while driving.

Add me to the list of Ram owners with the "Service Electronic Braking System" and "Service Antilock Braking System" error codes, 2018 Ram has 30K miles, the dash lights up with these two errors then goes away, then comes back.

Service Electronic Braking system and Service ABS braking system messages with accompanying chimes occur every 2-3 seconds while driving. This turns off the traction control and abs as well as the speed control. Diagnosis reveals abs control module and hydraulic brake control unit needs to be replaced. Code c0020-01,Vehicle only has 22,000 miles. Parts are discontinued according to dealer site. I started getting a Service Electronic Braking System warning light and bell recently that is intermittent and seems to affect the braking system on the truck. The light will go off and then return, sometimes once and at other times frequently. I searched online for this issue and found this is common among the 2018 and later year RAM trucks. The dealers make repairs under the warranty or charge upwards of $1,000 to change components to clear the warning, sometimes resolving the issue and at other times the warning returns shortly after repairs were made. My truck has just over 22K miles and the warranty (36 months) lapsed in October 2021. I believe RAM has adequate historical information regarding this issue to recall these vehicles and replace the failing components impacting safe braking on these trucks. Some vehicles exhibited this warning with less than 10,000 miles on them. There is plenty of owners complaints available via internet sites, such as the RAM Forum, documenting this safety issue and the lack of support by Chrysler to resolve the problem. FCA RamCares was at no help a

ABS and Traction Control warning light keeps intermittently coming on and then a message saying that the Electric Brake system needs serviced. Assumedly if the ABS is not functioning correctly that could lead to a crash. After doing research and reading many forums I see this issue has been reported many times and there is a TSB listed for this. For a truck with on 33,000 miles on it I would not think a critical component like ABS should be failing.

Intermittent shutting down of ABS. Which as a truck designed to pull heavy loads, this is a serious safety concern. This is due to a faulty ABS module that has plagued a disproportionately large number of owners. The problem remains that Ram is not supplying the needed part to remedy the safety related problem.

The ABS system warning comes on when I hit a bump. The audible warning sounds as well. It happens multiple times during a trip, even a short trip. The cruise control is disabled when this as well. When this happens, the truck is harder to stop. It is a safety concern. There is a recall on 2019 trucks for the same issue. The 2018 trucks need this same recall.

The electronic brake light and ABS warning goes off intermittent and with hitting bumps. When this happens the cruise control shuts off. This leads me to believe that the antilock brakes and and will malfunction in a panic stop. This is a repeat issue, dealership has replaced the HCU and ABS modules twice within a three year window.

Ram 2500 truck "Service Antilock Braking System" and "Service Electronic Braking System" warning light and chime come on and off repeatedly. This problem has been diagnosed by RAM dealer as error code C0020-01 ABS Pump Motor Control General Electrical Failure. Solution per RAM is to replace ABS Hydraulic Control Unit, MOPAR part #68143491AA/AB; however the part is unavailable and on backorder with MOPAR's ETA of December, 2022. This problem started in June, 2022. I tow a 5th Wheel on long trips and this problem is a serious safety concern for my family & I. There are a multitude of complaints on various forums about this issue and the fact that the part is backordered for so long is an indication of a serious defect. When the warning light is on, the ABS system and traction control systems are disabled causing a major safety concern. I would like Dodge/RAM to replace the failed components and pay for installation and/or issue a National Safety Recall to remedy this defect.

The abs pump and module have failed on my vehicle leaving it without abs, skid control and traction control. This is a very common issue and known by the dealers and manufacturer. This has affected tens of thousands of Ram trucks anywhere from 1 year old to 4 years old. But is only covered under warranty 3 years or 36k miles. It is my opinion this is a safety concern and should be recalled by the manufacturer.

The contact owns a 2018 Ram 2500. The contact stated that upon starting the vehicle, the ABS and traction control warning lights illuminated. The contact stated while driving at 45 MPH, the Service ABS and EBS messages displayed along with an audible sound. The vehicle was taken to the dealer for diagnostic testing where the hydraulic control unit was replaced. The manufacturer was not contacted. The failure mileage was 17,200.

Vehicle antilock brake system and traction control system failed causing cruise control to disconnect at highway speed, attempt to stop the vehicle caused an out-of-control skid

ABS module and HPU failing. The ABS Module is losing communication with the HPU causing the ABS to turn off and on. The concern is if it turns of during an event where it is needed and increases the chance of losing control of the vehicle.

The contact owns a 2018 Ram 2500. The contact stated that while driving 65 MPH, the ABS and traction control warning lights illuminated and the cruise control inadvertently disengaged, causing the vehicle to decelerate. The contact had not lost control of the vehicle or electrical power. The vehicle was taken to the dealer and diagnosed with electrical failure. The contact was informed that the hydraulic control unit needed to be replaced and a software update needed to be performed. The vehicle was not repaired. The contact stated that the dealer informed her that it was a common issue with the vehicle. The manufacturer was notified of the failure and no assistance was offered as the vehicle was not included in a recall. The contact stated that she researched the failure online and found a recall for the 2019-2022 Ram 2500 with a similar failure. The contact referenced NHTSA Campaign Number: 22V140000 (Service Brakes, Hydraulic, Electronic Stability Control). The contact stated that the VIN was not included. The approximate failure mileage was 70,000.

The vehicle entertainment center has an issue where the screen is separating from the unit. This is a SAFETY ISSUE because the system CANNOT be turned off and the unit controls not just entertainment features such as radio, navigation, etc but also controls driver functions such as seat controls, heat & air, cell phone connections, etc. The screen is a touch screen unit meaning that the separation issue causes the system to think random areas on the screen are being touched due to road vibration. This causes the vehicle's computer systems to freak out and do things like randomly call people if a cell phone is connected, change seat settings, turn on air conditioning full blast and then switch to heat full blast, select random navigation points, etc. This is HUGELY distracting to the driver and UNSAFE. An internet search will indicate that this issue has been a known issue by many drivers of Dodge RAM vehicles where this particular entertainment system is installed. It needs to be recalled and fixed. These issues render the vehicle UNDRIVEABLE without risk of causing an accident.

The electronic brake light and ABS warning goes off intermittent and with hitting bumps. When this happens the cruise control shuts off. This leads me to believe that the antilock brakes and and will malfunction in a panic stop. A brief review of google shows this to be a well known issue with multitudes of owner la having the issue. Parts on back order also an indicator of the frequency.

Diesel Particulate Filter (DPF) and other exhaust components. When the vehicle is in a "Regeneration" cycle and the vehicle comes to a stop, it dies about 70% of the time. Causing traffic back ups and nearly a reared collision from another driver. This issue started at 112000 miles and does it 3-6 times daily. It's been in and out of the dealer (Young Chrysler Jeep Dodge and Ram Richard Lindema Shop# 385-332-3978 Cell# 801-589-8943) totaling 6 weeks and $22,000 in repair bills and its still not resolved. I see on diesel forums this is a known problem that Dodge doesn't know how to fix.

Service Anti-lock Brake System; and Service Electronic Brake System warning messages appear constantly on the dash.

The ABS on my vehicle malfunctioned and the warning lights appeared on about 8/1/2022. The mechanic pulled the error code C0020-01 ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. His research indicates the solution is to replace both the ABS Control Module and the ABS Hydraulic Control Unit at the same time. As replacing one without the other seems to lead to additional unnecessary and costly repairs to the same part. After contacting every Ram dealer in my area, there are no ABS Control Modules available anywhere. I then checked the internet and it appears that the ABS CM (part# 68347098AB) is not available anywhere with over 2500 on backorder at a single RAM dealership in Texas. It appears that there are many thousands of RAM owners with the same problem and the lack of a replacement part is troubling. The ABS system in vehicles is a BASIC safety feature and a malfuctioning ABS will undoubable lead to crashes and possibly deaths. As a owner of an affected vehicle, I request that you investigate this problem and force RAM to ensure that their vehicles are equipped with the basic safety features that are required by law.

Service Antilock Braking System and Service Electronic Brake System randomly turning on and off once vehicle is started. Sometimes they do not turn on at all. Randomly occurring. The Alerts were not there one day, and the next they were. No moisture, rain, or hard braking occurred to cause this. This is causing traction control and ABS to turn off which will be a major safety hazard once winter comes. This turns out to be a very common issue with these models.

The abs and traction control light is on and chimes non stop and my cruise control will not work when the abs and traction control is defective.It needs the abs pump replaced as do many of these trucks. The next issue is the computer sceen is delaminated and is wanting you to adjust the time and chimes non stop, so it will not allow you to turn on your defrosters so you can see the road. This truck is so unsafe it now just sits in my barn while I drive my 2005 ram with 210000 mile on it! The repair cost is around 5000,00 for a truck with 48,000 miles on it! All safty issues!

Keep getting service ABS system message. Doesnt matter weather conditions or road conditions, it is very random and becoming very frequent. Upon doing some research to figure out the issue, it has become apparent that this is a very common issue with Ram. The Hydraulic Control Unit needs to be replaced as stated by my mechanic that pulled the C0020-01 ABS Pump Control Motor General Electric Failure code. There are way to many websites and forums to list for reference but the issue can be found with a quick google search. Ram knows this is a problem and thats why they are limiting how many of these parts the dealer can get.

Transmission abrubtly shifts into 4th gear and will not shift up or down. Cannot manually shift either. Must pull over and shut off vehicle and restart.

All started when the truck had 472 miles. ESC and service brake light came on. Was repaired on May 9, 2019. March 23, 20 back at dealer for ABS Light and ESC Lights on dash. Dealer replaced both the HCU Unit and ABS Module on truck. December 2, 2021 back at dealer again for the same HCU and ABS Light on dash again. Dealer replaced HCU unit but not ABS Module. August 2, 2022 HCU and ABS lights on again. Contacted dealer they said they would call back with service date but never got a call back. This is a very serious safety issue on these trucks. When the ABS and ESC Lights are on in the truck it disables the Antilock Break System along with traction control, brake controller and if you have 4wd it disables that also. I have had nothing but problems with this truck since it had 472 miles on it. Dodge/Ram refuses to address the problem correctly. They just put another part in knowing it will fail sooner or later and by that time your waranty is out and they want $1600 to repair something they know will break again. What will it take to have them correct this problem (someones life!) I will never but another Dodge product again. They refuse to find a fix for this problem.

ABS Module failed which makes the truck slide and lock up the brakes and makes cruise controll not work at all also turns off traction controll which can make the truck slide or skid in turns or on wet conditions.

I had to brake hard on the freeway to prevent being hit by an 18 wheeler that began to change lanes. Since that incident, every time I press the brake pedal more than 50%, the "Service Electronic Braking System" light flashes on the EVIC. I had the ABS pump replaced in July 2020 under warranty for the same issue, and was advised that it is a known issue, but there was not a recall that has been issued. I have not had any issues with the brake system since the repair until I actually needed it in this instance. This is a safety concern due to the fact that when this occurs, it disables the ABS system.

May 18 2020. 6,783 miles on truck ABS light and traction control light started flashing on and off. Drops out of cruise control. Then light stayed on all the time. Dealer replaced the complete brake system. Yesterday July 20 2022 same thing again at 39000 miles.ABS and traction control light on. Dealer said it's out of warranty. There are complaints of this issue all over the web and has been a issue for years. Why is this not a safety recall yet.

2018 Ram 2500 with 41,900 miles. ABS and Traction lights started coming on. Had to have the hydraulic control unit replaced. Seems like a known issue and very unsafe to lose abs or traction control. Ram should take notice.

The hydraulic control unit for the ABS brakes failed at only 17000 miles. This is a known safety issue with these trucks.

Service antilock brake system and service electronic brake system warnings come on

Brake system failed on 2018 Dodge Ram 2500 with 31,262 miles on it. Dealer stated electronic failures on ABS pump and hydraulic control unit.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, an ABS warning message was displayed on the instrument panel. The contact had taken the vehicle to a dealer where they informed him that the ABS module and hydraulic control unit needed to be replaced. The contact was given an estimate for the repair; however, the parts for the repair were on backorder. The contact called several dealers and each informed him that they also did not have the parts available. The manufacturer had yet to be notified of the failure. The failure mileage was 29,719.

2018 Ram 2500 4x4, 65400 miles, began having flashing and dinging from dash and warning lights for abs, traction control. Scan revealed code c0020-01, ABS control general electrical failure. It appears FCA is aware of this issue, but claims it not to be a recall issue, or covered under the power train warranty. I feel this is a safety issue, these systems help avoid crashes. This started as a simple quick light and went away, and at other times it goes off and on and dings, it’s distracting to who ever is driving these vehicles,

While driving my ABS system “ service ABS” and Service Electronic braking system “ light both flashed and my truck started to skip as it appears the abs system was trying to engage while i was driving, I immediately pulled over and turned off the truck. Now the lights won’t turn off. I was driving about 60 on paved roads. This appears to be a severe problem with the 2018 year model and if not taken care of I will bring legal action against Fiat Chrysler Ram and the NHTSA for ignoring these real issues that could potentially lead to a death

The check engine light came on and vehicle gave a 196 miles to reduced power and shutdown warning. Vehicle was taken to dealer and diagnosis was that the Diesel Exhaust Fluid gauge and pump assembly had failed. Repairs were made at dealer. Failure of this part can put the driver in a situation of reduced power and danger while driving on highway.

-Anti lock brake system control module and traction control system failure with 32000 miles on truck.- In reading online forums they have admitted to knowing these parts were bad. Not sure why this hasn’t been made a recall issue given it involves the braking systems on a huge portion of these trucks sold.- Dealership states both parts are bad but excluded from warranty and extended warranty.- warning lights come on at the same time it locks the brakes up until warning lights go out. -Well at 70 mph on the highway and it locked my brakes up. I was just lucky it didn’t cause a wreck or roll over accident which it very easily could have.

The EVIC display showed Service Antilock Braking System and alternated to Service Electronic Brake System. It would constantly ding and display the ABS light and the Traction Control light. It disengages the ABS and traction control system. Research has shown me this is a very common and known issue. It is dangerous and I am not comfortable driving my vehicle in the weather conditions I experience while towing heavy loads on a daily basis.
