2018 RAM 2500 Electrical System Problems

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed and became firm. Additionally, the service electrical braking system warning light was illuminated. The vehicle was taken to the dealer, who diagnosed the vehicle with an ABS hydraulic control unit electrical failure; however, the vehicle was not repaired. The part to do the repair was on backorder until August 16,2023. The manufacturer was made aware of the failure. The failure mileage was approximately 78,000.

Service ABS and electrical brake system failure lights come on randomly and repeatedly. This also disengages the cruise control when it happens. Sometimes the warning light stays on for a few minutes, other times it flashes on and off and dings each time. This is a very common issue for this year of Ram truck from people that I know and from the research I have done. At my previous employer, we had 2 other rams the same year with the same issue. The ABS system will not work with this problem - I was driving and my vehicle skid due to there not being ABS. I have tried on multiple occasions since my truck had about 85k miles on it to get this problem repair. The dealerships all told me they dont have the parts for a repair

Service lights for ABS and traction control systems constantly going on and off during vehicle use, these system failures disable cruise control systems. Truck is at dealer and they have said it needs new hydraulic control unit and ABS parts totaling over $2000 in parts alone, without an idea of when the parts will be available. This seems to be a common failure as I have read many posts of other Ram owners with the same issues.

I keep getting an intermittent error code on my vehicle C0020 - ABS Pump Motor Control. General Electric Failure After doing some research on the internet it appears that there are a lot of 2017 & 2018 Ram 2500 owners with the same issue

This complaint is based on the repeated failure of the vehicle's ABS/Traction control system and the lack of a repair solution from Ram. The failure starts as an infrequent (once per trip or so) fault and immediate clear of the ABS system with an audible alarm and dashboard message. Over the course of a few hundred miles the problem worsens to the point where it it faulting as often as every 1-1/2 to 2 seconds. (It is like driving with the seatbelt warning going off). Sometimes it will stay faulted or cleared for several seconds to minutes at a time. In the beginning of the failure process it seemed to go away once the engine got fully warm, after about 10 minutes of driving. This problem was diagnosed and repaired at a diesel specialty garage with replacement of the ABS Control Module and Electric Stability Control Unit. Reprogramming was performed...

The abs traction control lights keep coming on device abs service electric brakes I pull a camper afraid I may loose my brakes and no parts available

Hydraulic control unit was replaced July 2020 (ABS traction control lights coming on MEANING, NO ABS NO TRACTION NO 4 WHEEL DRIVE.) Hydraulic control Unit not working AGAIN. I have NO ABS, NO TRACTION, NO 4 WHEEL DRIVE, AGAIN. CHIME GOING OF CONSTANTLY AND DEALERSHIP HAS HAD "PART ON ORDER SINCE JAN 2023"

HCU, ABS Modules. Inspection Is Available Apon Request. Concern For Safety With Hard Brake Pedal, Not Stopping As Required. Modules Do Not Respond To Hard Braking Like Described. Speedometer Not Reading. I Changed The Cables To The Wheel Hub With Still No Response. 42,600 miles In It, No Accidents. Problem Started 8mo. Have Not Driven For 3mo Now. Safety Not Confident. No Dealer, Mechanics Only A An Advanced Code Reader Scanner. Engine Light, ABS, Car/Lane Symbol Display.

Abs braking system has been flashing and traction control light flashing. My left front wheel started grinding and smoking out of the blue when driving today. No problems with brakes before that. Cruise control doesn’t work. And four wheel drive service light is flashing again!! The four wheel drive sensor was replaced once already a couple years ago.

Was driving vehicle on a rock road, when rounding a slight curve in the road, the antilock brake system light and the traction control lights both illuminated at the same time. The rear end of the truck began to slide due to having light pressure on the brakes and I was pulling my fifth wheel camper. Fortunately there were no injuries or damage to the truck or the camper. I washed off the mud when I got back to a hard surface area that had a car wash available and continued on my journey. Approximately 30 more miles later on the same trip both warning lights came on again. I immediately pulled over to read the message warning that was up on the dash to see if I could continue with my journey or not. After reading the message on the display in the truck, I decided it would be...

There seems to be a huge ongoing problem with ABS pumps and control modules for this model vehicle. I can find pages and pages of issues online for the same truck. The 'service brakes' warning comes on and off intermittently and I managed to replicate the fault after several months long enough to get it diagnosed. I am told the following parts are the issue: 68347098 - AB MODULE AN 08035030 68143491- AB CONTROL A 08035030 I got the truck diagnosed in January but was initially told Mid March for the parts and now am being told August - which would mean no functioning ABS on my vehicle for 8 months! And no guarantee the delivery date won't creep again. This is unacceptable for a safety critical component and clearly shows a fundamental flaw with the parts as they can't seem to make them faster than they are failing. I...

ABS light and Tracking control lights flicker on and off constantly. No warnings just came on one day. I have 38,000 miles on my truck not very many for warning lights to come on. I cannot use cruise control as well as about half of my controls. Including tracking control which is now permanently off and is a major hazard! Took it to the dealership in Concord, CA and was told the control module is bad. With no time frame to fix. Probably will be a fix once my warranty is up so the dealership is not liable to fix my truck. A quick search online shows this is a problem for this vehicle.

Driving along freeway to visit family, cruise control engaged, travelling 65 mph, when all of a sudden several messages flashed on the dash to "check electronic braking system", and traction control disengaged light and service light came on as Cruise control shut off. after a few seconds lights went out and system returned to normal. Repeated several times on way back home (3 hr drive) and had randomly happened since almost every time I drive the truck. Had similar situation a year after I bought the vehicle, 11/2020 @6600 miles, local dealer replaced HCU. This can potentially leave me without Traction control and ABS when I need them and could cause an Accident. I'm waiting for dealer to get other parts in for a covered warranty repair, (Been waiting since Nov 2022), and have them fix both, again, but it renders my truck useless- dangerous to drive until then.

ABS Code C0020-01

“SERVICE ANTILOCK BRAKE SYSTEM” and “SERVICE ELECTRONIC BRAKING SYSTEM” lights come on and off repeatedly.

The abs module and hydraulic control unit has failed. This means that my safty and others on the road is put at risk because during heavy breaking you can loose control of the vehicle due to the truck anti break system does not work. Also the traction control does not work which also will cause you to loose control.

Multiple ABS pump and ABS hydraulic control unit failures. Components have been replaced and replaced components failed also after a few months.

The abs and traction control lights come on and go off intermittently. I took the truck to the dealer they said it need a new hcu which costs 500$ and 1000$ for labor the truck has 27000 miles on it and is out os warranty. The part need is on back order. I feel this is a defect and there should be a recall. Thanks for any help you can give. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Code for right rear wheel speed sensor came on. Resulting in no abs,traction control, 4x4,or parking sensors. I bought new part from dealer had mechanic change it. Reflash abs and still on. Went off briefly for 5 seconds came back on. I've realized it's it's common problem. Resulting in the abs module needing replaced. But it's only a temporary fix.

ABS and stability control fails and warning lights activate intermittently 11/11/22 (47,290 miles) The cruise control disengaged without notice when the faulty modules light up. Under a heavy load this caused severe speed reduction and momentary loss of vehicle control Reported to dealer.(Rothrock motor sales) It is a know issue with thousands of suspect ram 2500's Parts are not available due to demand. This is an intermittent fault with the Stability control and/or hydraulic control module. Both parts or one part faults the other creating a hazard for all drivers Dealer was made aware of issue and states parts are back ordered months out if at all available causing customers to drive the trucks with unsafe braking due to no other means of transportation This is a well know defect being ignored by Chrysler/Ram

At 67k mileage my 2018 Ram 2500 abs, traction control and electronic braking system warning lights flash intermittently, dealer, auto parts store and several online sites state it is the ABS and HCU modules electrical failure. This causes the abs system to malfunction and poses immediate threat for crash especially while pulling trailers. When the lights flash the cruise control will no engage/disengage. No dealer has these module with no clear indication of availability as of 1/27/2023

Abs on off messing with cruise control. In snow conditions feel it’s a concern. Sometimes the abs work’s most of the time it’s on/off multiple times while driving. For a 2018 truck with only a little over 24,000 miles not happy that at this time the dealership says they have no clue when they will have parts to fix

The infotainment screen is malfunctioning. It makes phantom button presses. The most dangerous of all is when I am backing up. Instead of it showing the back-up camera it shows the bed camera. Very dangerous!!!!

I have made a previous report about this vehicle. New things are happening now. My mirrors are tilting and changing while driving. The backup camera is still coming on in while driving down the highway. I can't keep the heated wheel turned off. It gets so hot, its hard to hold the steering wheel. I have to pull off the road and turn the truck off. I cannot use my Bluetooth while driving because it starts calling random people, then it starts reading all my text messages. Its against the law to hold your phone while driving in NC. The doors lock and unlock while driving. I bought this truck a little over a year ago and this ghost in my truck is driving me crazy. It's unsafe while driving, with the mirrors tilting. I change the settings and the ghost changes it all... please help.

Anytime while driving the truck waring lights on the dashboard will come on intermittently. The ABS and traction control light will come on, and on the display screen two different messages will appear along with alarm sound constantly dinging. One message says (Service Electronic Braking System) the other says (Service Antilock Brake System). If driving with the cruise control on when those lights and messages appear the cruise will stop working. This problem is intermittent it comes and goes, but usually very often. The truck is out of warranty with 41000 miles on it and this has been happening since Sept. of 2022. I had it diagnosed by an independent garage and had two trouble codes (C0020-01 ABS Pump Motor Control General Electrical Failure) and (C0020-16 ABS Pump Motor Control Circuit Voltage Below Threshold). The truck still seems to stop normally, but I feel very unsafe driving it. The ABS...

- I have a repeated low mileage failure of the antilock brake system hydraulic control unit. The faulty unit is still installed on the vehicle. - The ABS hydraulic unit failure intermittently renders the ABS system, traction control system, and electronic stability system inoperable for varying durations. This is the 2nd failure of this system on the vehicle. The first failure occurred during normal highway driving. The 2nd failure occurred while traveling in the mountains in the snow. Had I not been experienced driving a non-abs vehicle in inclement weather we could have crashed. - The issue was diagnosed and confirmed by a local Ram dealership service department. It was escalated to Ram customer care due to lack of parts availability and high cost of repair. Ram escalated part delivery and denied financial assistance. The vehicle is out of warranty for this particular part. - There are various intermittent warnings...

Abs and traction control lights come on and off dealership replaced the hcu and the problem stopped. 2 years later and only 3,000 problem started again. Contacted the dealership and they said its a known issue but no parts are available and no recall

C0020-01 code began coming in and out immediatly following a service at my local Ram dealer. I returned to the dealer after the warning lamps and messages all came in around ten times within a mile of picking my truck up from them. The dealer used a device to clear the messages, but the alarms returned again after I left. There are multiple warning lamps and messages that remain in as a result of this: service anti-lock braking system, ABS warning lamp, traction control lamp, and a loss of cruise control functionality. While the constant "dinging" sound and loss of cruise control on a truck with less than 20K miles is disappointing, I am concerned whether or not these warnings are indication of a serious safety hazard to my family and/or those we are on the highway with. My truck is available for inspection. The issue was confirmed by my...

The ABS module and associated control unit have failed. This causes the anti lock braking and traction control systems to be inoperable which can cause the vehicle to lose control which can cause injury or death. FCA is aware that these units are defective and refuses to fix them.

Traction Control Light is illuminated, Service Trailer Braking System, and Service Trailer Brake System Notifications are present on engine startup. ABS system appears to be inoperative in slippery conditions. Service Engine Light comes on every 15 miles or so with Codes P0572 and P0572pd. Download codes and they go away.

Multiple failures on ABS Brake control module. Module has failed twice now within 30,000 miles. Manufacturer has no urgency in prdocing replacement parts. Cannot drive vehicle due to this issue.

ABS and Traction Control warning lights flash on and off constantly and there is a warning tone that beeps non-stop on my 2018 Ram 2500. When these warnings appear, the ABS System and the Traction Control are disabled along with the cruise control. This has happened twice already, and my truck only has 4000 miles on it. The first time was in October 2021 when the truck had under 3000 miles on it. The dealership replaced the ABS pump which fixed the problem temporarily. In August 2022 the same problem appeared, and the same warning lights came on. At this time the truck had around 4000 miles on it. I took the truck in for service in October 2022 and even though the truck was out of warranty, I still had an extended warranty contract. This time I was told it was the ABS Control Module and that the part...

Sporadic light warnings displayed on dashboard along with warnings of Traction control and Service ABS control module. C0020-01 code pulled with code reader. Dealership diagnosed that ABS Pump motor control failure and replacement was needed. Parts on recall until earliest Jan 2023.

In July 2022, the esc/abs dash lights as well as the ‘service electronic brake/service ABS’ warning began intermittently flashing with resultant loss of traction control and ABS including cruise control. It would continue to activate/deactivate numerous times over the next couple of months. The dealer has identified the hydraulic control module as defective requiring complete replacement of the HCU and ABS system. Online search shows this to be a common known problem along with well over 100 complaints filed with the NHTSA regarding model years 2017-2018. Interestingly, there is a recall for this very problem for the same truck series years 2019-2022 for the same part. There are over 2500 orders for this part and my dealer is not allowed to place an order until mid February because of the backlog endangering my life to use my only vehicle that can be used in the snow this winter. Dodge is...

The ABS light will go on and off the dash over and over. The truck is 134 miles out of warranty and the dealer said the parts are the ABS pump and electrical board went bad. They do not have the parts to fix then and it is not warrantied now. This is a well known problem and there is plenty of knowledge at the dealers of the issues. They knew what was wrong without even driving the truck. The pump going bad at 36, 239 miles on my truck should not happen. They already have an updated fix but will not admit they sold trucks with a faulty ABS design and should be fixing these trucks for free. My ABS no longer works and I have no cruise control or traction assist and I live in the snow belt of Ohio. I no longer feel safe driving my 4...

In February of 2022 the radio console screen looked odd. It was very subtle and we weren’t sure what if anything we were seeing. The function was normal at that time. At this time the vehicle was under warranty and had less than 28,000 miles. It was having an intermittent check engine light in July and was due for service so we took it to the dealer. I told them about the console screen appearance and they said it was delaminating which they were seeing in these trucks. They did not say it was a recall issue. Since the replacement unit was over $1,000 and appeared to function otherwise we opted not to change it. In December the screen began to flash and act strangely. When we tried to start it the next day to take to the dealer, it had no power. We had it towed to the dealer...

Lost braking power. Anti-Lock brakes quit working. Lost cruise control. Unable to use anti-lock brakes. Brakes locked when stopping. Flashing dash alarm saying service ABS/Electronic Braking System. All occurring without reason, just randomly. This puts my safety and the safety of others at risk as the brakes lock up when depressed at times as well as loss of braking power.

Was driving on expressway exit ramp trying to come to a stop and the brakes hesitated and then locked up, at the same time the traction control and abs light came on. Traction control and abs lights still come on months later and problems with breaking are still there. Took to local shop to get fixed and they told me abs module and hcu pump are bad. Parts are not available thru mopar or aftermarket.

ABS system malfunctioning, “service electronic braking system” and “service abs” messages flashing continuously while driving. Known issue among Ram. Was quoted $1000 to repair ABS module.

Service electronic brake system indicator came on while driving vehicle. Warning continued to go on and off numerous times randomly and still continues to do so. Took it to dealership to have problem addressed and service worker said this was his sixth 2018 Ram 2500/3500 in his dealership to have the HYDRAULIC CONTROL UNIT and ANTI LOCK BRAKE module to malfunction. FCA should have a recall on this, but as of now they don't. Parts are back ordered and won't be in for months. Dealership told me it's fine to drive as is but I'd rather not take my chances. Please address this. Thank you very much.

HCU failing. Blinks on display screen. Appears then disappears. When in cruise control and the HCU goes haywire, kicks cruise control off unexpectedly. When this occurs and the driver isn't expecting it, this causes panic because the vehicle rapidly slows down, nearly causing a vehicle collision if not prepared for it. I was almost rear ended due to this. Research on this failure would reveal this issue to be affecting 1000's of 2018 RAM trucks to have this problem. My local Dodge dealer advised I am approximately the 2500th person waiting on the part which is currently on BACKORDER. Have been a Police Officer for 15 years, safe driver and this nearly caused an accident on 695 Baltimore County, MD during heavy traffic.

A few weeks ago, the seat and steering wheel was so hot, I could hardley hold the steering wheel to drive. I immediately checked the controls for the heat, it was on and I turned off, it turns back on. I finally found a safe place to pull over and went to settings and made sure it was off. It automatically comes back on, then it wouldn't let me turn it off. Finally it switches to cool seats, then then fan is coming on wide open and I couldn't turn that off. I finally shut the truck down for a few minutes. Then restarted the truck, then the truck wouldn't go in drive, it was stuck in park. I kept working with the shifter and finally got it in drive. As soon as I pull back into traffic, the backup camera is on, the radio starts going crazy, going from...

The truck ABS, traction control, and service electric brake lights and warnings have flashed and beeped on and off and on and off every few seconds. I took the truck to the dealer to be fixed under warranty. The dealer states it has a bad HCU and no longer has anti lock brakes however I can still drive the truck with all that distraction going on in the dash. The part is on back order and I won’t have my truck repaired until February (2.5 months) This same part was also replaced a a little over year ago under warranty along with Abs sensors and wire harnesses. I have 2 friends with the same year trucks who also had to have the same repair done. Upon looking up information on the internet it seems like this has been a on going issue on the 4th generation ram trucks 1500-3500 models...

The LCD touch control screen in the dashboard has been delaminating for several months and is now malfunctioning causing the screen to change turn on and of settings such as heated seats, heat and AC. The screen will not remain off at night due to this malfunction causing an unsafe and distracting bright light coming from the screen remaining on.

The contact owns a 2018 Ram 2500. The contact stated that after two weeks of not driving the vehicle, the vehicle failed to start up after several attempts. Several unknown warning lights were illuminated on the instrument panel. The contact jumpstarted the vehicle and made an appointment with the dealer. The vehicle was taken to the dealer who informed the contact that they could not duplicate the failure. However, the dealer replaced the battery. The contact stated that the failure persisted. The vehicle was taken back to the dealer on two other occasions; however, the dealer could not duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 19,000.

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.

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.

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.

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...
