2018 RAM 2500 Electrical System Problems

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.

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!

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.

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

My 2018 RAM 2500 doesn't even have 23,000 mile on it, however went out of the 3/36000 in June of 2021. Currently I will be driving along and out of the blue the ABS/EBS "Service Breaking System" and traction control will light up and flash and ding. It will sometime go away quickly, however other times it keeps flashing the warning, and dinging upwards a minute. As seen on the site this is a very common issue with the 2018 RAM 2500, and it should be a Safety Concern and part of a National Recall. Many people use the 2500 to pull trailers and the like, and to loose any safety aspect relative braking is simply unacceptable and a dangerous situation for the owners and others on the roadways.

While operating the vehicle on cruise control the electronic throttle control failed and the vehicle went to full throttle. Stepping on the gas did not fix the problem. Luckily the brake lamp were applied and the brakes slowed the vehicle to a stop eventually while the engine was still at full throttle. Once the vehicle was safely on the side of the road, it was turned off. The vehicle had a warning that said to service the electronic throttle control. The vehicle was started again to get it onto a tow truck once it arrived, and the vehicle still went to full throttle. The vehicle was towed to the nearest dealership. Once at the dealership the vehicle was started again to get it off of the tow truck. The engine operated normally at that point. The throttle failing to full throttle is a huge safety issue. Luckily there was minimal...

I have been having intermittent ABS/traction control lights flashing on my dash. When I hooked my truck up to my DTC code reader, it says I have a C0020-21 stored. ABS pump motorcontrol - general electrical failure. I have noticed thousands of complaints on various websites about the same issue. My truck only has 38,000 miles on it. This must be a defective part.....I called and asked my local dealership about this and they said its a very common issue. I believe it is a safety issue because it reduces the trucks ability to stop quickly, it may cause my truck to swerve in an emergency stop situation, and if this happens while the cruise control is on it turns the cruise control off unexpectedly. This happened to me in a bad rainstorm and caused my truck to swerve into the next lane over. I asked the dealer when they...

I was on vacation with my family and pulled over to the side of the road to get something from the back and the service abs electronic light came up. it was intermittently coming on and off. it really dampened our trip because i have been stranded with electrical issues in this truck before. my family was scared the brakes were going to fail and we reduced our trips into the mountain areas we had planned. being not fully trusting of this very expensive vehicle i thought would take me anywhere i need to go i tried to sell it back to the dealer, i signed all the sale paperwork feeling like today was the best deal and they wouldnt give me the same deal the next day. only to be told i needed to pick the truck back up because of the brake system hydraulic control and brake system...

SERVICE ELECTRONIC BRAKING CONTROL AND TRACTION CONTROL LIGHTS COME ON AND CHIMES. AFTER SEVERAL TRIPS TO THE DEALER AND MOST OF THE TIME THEY COULD'T DUPLICATE THE PROBLEM I FINALLY HAD THE LIGHTS TO COME ON AND WENT STRAIGHT TO THE DEALER WITHOUT SHUTTING DOWN THE TRUCK AFTER THE CHECKS THEY STATE ABS CONTROL MODULE AND HCU NEEDS REPLACED. PARTS ARE UNAVAILABLE FOR AT LEAST 6 MONTHS AND $1200 REPAIR COST. THE LIGHT COMES ON THEN THE CRUSE CONTROL STOPS WORKING AND THEN WHEN BRAKING HARD THE WHEELS LOCK UP AND CAUSES SKIDDING. TO ME THIS IS A SAFETY ISSUE THAT RAM NEEDS TO STEP UP AND REPAIR. ITS FEDERAL LAW THAT MANUFACTURES PUT ABS ON THE VEHICLES SO THEY SHOULD MAKE SURE THEY WORK CORRECTLY.

Every so often I am getting the “Service Electronic Brake System” and my ABS light and Traction Control Light come on. This has happened to quite a few Gen 4 and Gen 5 Ram’s. Everyone replaces the wheel speed sensors, wheel hubs and ABS sensors with no fix. Only thing after that is the Hydraulic Control Unit and ABS Control Module (which is on National back order until who knows when). The ABS system for some reason is not covered under the power train warranty, why I don’t know. It’s a serious issue that needs to be addressed.

Hi 2018 Dodge Ram 2500. Screen for radio/gps/Uconnect etc is delaminating.

Steering dang link , steering gear box has my steering throwing me all over the road . It's getting bad to almost causing wrecks and suspension is very bad . This has been getting really bad to the point of calling a lawyer

The ABS and Traction Light come on intermittently. We recently had snow fall and I had to stop quickly, the ABS worked as it should have until the light activated on the dash which disabled the ABS. Luckily I was able to control the vehicle when it started to slide into the on coming lane. It is definitely not safe. As I have seen in numerous complaints this is a well documented problem on the 2018 Ram 2500.

Service Anti-Lock brake system and Service Electronic brake system messages repeatedly display along with a distracting chime. Symbols for these illuminate and then go out. The dealer spent three and a half hours trying to determine the problem about a week and a half ago. They made an appointment to pick up the vehicle this morning to look at it again "after their electronics specialist gets back from vacation". No one picked it up and a call to the dealer revealed that they have no drivers available to come get it. The constant chiming of the warning is especially distracting when driving in traffic and the intermittent nature of the problem could actually cause an accident if it occurred while the systems were trying to control a skid.

My 2018 Ram 2500 has over 45,000 miles on it and this is the second time that I have gotten the service antilock brake system and service electrical braking system warnings. The first time my truck was still under warranty and the dealer replaced the parts (I believe the ABS module and the hydraulic control unit) which seemed to remedy the issue until recently. Now here we are with the same issue coming up. Seems that the first time occurred when turning on a wet road and the second occurred while backing up in some mud at our camp. Seems like the culprit might be when one of the rear tires seems to slip/spin differently than the other. Considering this is my second issue with this and there seems to be more and more complaints online for the same exact thing, this might be a defect in the parts or...

The contact owns a 2018 Ram 2500. The contact stated while driving 60 MPH, the Service Electric Braking System and the ABS and Traction Control warning lights were illuminated. The contact took the vehicle to a local dealer, where it was diagnosed with needing the ABS pump to be replaced. The vehicle was not repaired but was pending repairs. The manufacturer had not been informed of the failure. The failure mileage was approximately 26,800.

The Uconnect 8.4 system has failed, in that the screen has delaminated. This system affects all others. The climate control, Bluetooth, Sirius and Radio, rear view camera, and navigation system are all controlled by the Uconnect system. The system self initiates, cannot be turned off, and randomly changes audio sources. The navigation system does not track with the vehicle and the Bluetooth will not engage or disengage with driver input. Additionally, the Bluetooth will automatically engage and disengage during phone calls. This system was an expensive option, and now does not operate properly. It is extremely distracting. As I said, the system cannot be turned off and expected to stay off. It operates random and autonomously.

The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the U-Connect display screen malfunctioned, causing light to be present inside the cabin of the vehicle and causing a visibility hazard for the driver while operating the vehicle in the dark. On one occasion the driver nearly hit a pedestrian due to the poor visibility caused by the defect. The local dealer and manufacturer were notified of the safety issue, but no assistance was offered. The failure mileage was 80,000.

8.4 Uconnect (media center) screen delamination causing "ghost touches"/glitches on the touchscreen, which prevent backup camera from functioning. While backing up, camera randomly turns off or switches to a separate cargo camera. Backup camera often remains on while driving forward. Ghost touching also cause random phone calls and emergency phone calls, which cause a distraction to driving. According to simple Google search, 8.4 Uconnect screen delamination appears to be a common problem even on low-mileage vehicles. Manufacturer/dealer will not replace outside of warranty.

The Service Electric Braking System and the Service Antilock Brake System warning lights come on with chime. I or other have not been put into risk of safety as of yet. No dealer will look at it right now. I have called 2 dealerships and they both told me that they have to many vehicles as of now to look at it. At what point is mine and others safety con into play? I need my truck for my business and can't afford to let it go for long.

The rear backup camera intermittently goes out when backing up. Alot of the time it just don't work at all and you'll get a blue screen or a very hard to make out image that's extremely blurry. I'd have a feeling that this problem is more if an electrical connector problem because you can slam the tailgate and it will go back to working just fine for a little while till you hit a bump in the road or open your tailgate again. It can be extremely dangerous not being able to use your backup camera in such a big truck.

Abs and electronic braking system pump failed and need replaced around 40,000 miles. Was told it is a common known issue with these trucks

While driving my 2018 Ram 2500, the Service Electrical Breaking System and Service Anti-locking Break System flashes on and off. It usually does this while traveling on a bumpy road or driving over railroad tracks. Sometimes it will go days without coming on and some days while driving it constantly beeps and flashes the entire time while driving and it really distracts me from driving. When I called my local Ram dealership Lander's Dodge Bossier City, to make an appointment, they knew that it was a 2018 Ram 2500 before I told them. The first available appointment isn't until 22 November 21.

The contact owns a 2018 Ram 2500. The contact stated that the central control system head unit malfunctioned and turned off. Additionally, the head unit would activate or deactivate other systems in the vehicle without driver input. The contact had taken the vehicle to the dealer who diagnosed that the central control system radio head unit needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the issue. The approximate failure mileage was 29,000.

The truck was in at 35,486 miles because the service four-wheel light was coming on while towing the dealership said the electrical connector to front axle disconnect is packed with grease pushing pins from the electrical connector cleaned excessive grease from connector and repaired pins and reassembled Road tested verified repair shortly three weeks after the service ABS light has been coming on and off when it comes on with the cruise control on it causes sudden deceleration also when the service ABS light is on anti-lock brakes do not work and traction control light is also on it comes on and goes off while driving just like the service four-wheel-drive light I have not had it in yet for service due to the fact still fighting with warranty but to me it seem like an electrical short issue

Center console touchscreen is de laminating and executing vehicle functions on its own while I’m driving. Very unsafe and distracting. This is apparently a very common issue.

C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE. I called the dealership and was told by service advisor at Maik Haik Dodge in Temple, Texas this is a common issues and Ram knows about it. It is effecting Ram trucks from 2014 to 2018 models 1500 to 3500. This issue turns off all ABS, Traction Control and Disables cruise control. The Abs and traction control light goes off and on constantly. message on the dash is service ABS system and service electric brake system.

Touch screen delaminated causing random inputs and essentially disabling phone, SOS feature, rear parking assist, climate control, audio input control, BlueTooth, etc.

ABS module, HCU module Currently available to be inspected if dealer won’t fix. Potential loss of brakes. Dealer confirmed I had codes relating to a known problem with both abs and hcu modules. Dealership ran diagnostics. Service braking system warning lamp appeared on dash. Codes C0020 and U0147. FCA star letter case #: S2005000004 Letter relates to codes stating general electrical failure. Dealership wants to charge me $785.21 to fix. They started by saying the cost would be close to $2800, when I asked why so much, they said I need several other repairs but couldn’t provide a break down. I brought my vehicle in with the letter about the faulty equipment and the codes and was told it would get taken care of.

the service abs and service traction control come on if i hit any bump on the road, seems to be a common problem with this vehicle model.

The contact owns a 2018 Ram 2500. The contact stated while driving at undisclosed speed, the contact pressed the auto memory button on the front driver’s side seat and became aware that the electronic control unit on the vehicle had reset itself and radio which caused the front driver’s and passenger’s side rearview mirrors to open and close independently. Additionally, the front driver’s and passenger’s side windows activated independently. The contact stated that the failure recurred several times. The vehicle was taken to the local dealer and diagnosed the failure with an electronic control unit failure however, the mechanic was unable to duplicate the failure. The contact took the vehicle to another dealer, Wake Forest Dodge RAM (10936 Star Rd, Wake Forest, NC 27587, (919) 899-4586) who inspected the vehicle and confirmed the failure with the electronic control unit in the radio. The unit was replaced however, the failure persisted....

I HAVE A 2018 RAM 2500 WITH 24320 MILES ON IT. THE TRACTION CONTROL LIGHT/ ABS/EBS SERVICE LIGHTS COME ON WHEN DRIVING. THE SPEED CONTROL GOES OFF. I HAVE SEEN ON THE RAM FORUM THAT THIS IS COMMON ON THIS AND THE 2017 YEARS TOO. MY QUESTION IS IF THERE ARE SEVERAL 100 PEOPLE WITH THE SAME PROBLEM. WHY HAVE YOU NOT ISSUED A RECALL. THIS WILL GET SOMEON KILLED IF THEY ARE NOT CAREFUL.

CONSISTANT FLASHING UP "SERVICE ELECTRONIC BRAKING SYSTEM" AND "SERVICE ANTILOCK BRAKING SYSTEM" WHILE DRIVING. DEALER HAS ATTEMPTED TO REPAIR REPLACING ABS MODULE AND HCU, BLED AND RECALIBRATED THE BRAKING SYSTEM. ISSUE RETURNS AFTER FEW THOUSAND MILES. ONLINE FORUMS SHOW A LOT OF OTHER OWNERS OF THIS TRUCK WITH THE SAME ISSUE. BRAKES SUDDENLY FAILING IS A SERIOUS SAFETY ISSUE! FIRST ISSUE WAS AT 14K MILES, RETURNED AT 37K MILES. THE ALERT COMES UP AT RANDOM TIMES SUCH AS DRIVING DOWN THE HIGHWAY AT 70 MPH OR SITTING AT A LIGHT. DOES NOT SEEM RELATED TO ACTUALLY ENGAGING THE BRAKES TO HAVE THE ERROR.

SPORADICALLY VEHICLE WILL NOT START. DASHBOARD LIGHTS FLASHING, DISPLAY TOGGLES THROUGH WARNINGS, IDLE NEEDLE AND SPEEDOMETER NEEDLE MOVING WHILE PARKED, VEHICLE NOT ON. THIS HAS HAPPENED SEVERAL TIMES. LOCAL DODGE DEALER IS CURRENTLY ON 3RD VISIT TO REPAIR.

THE TOUCH SCREEN ON THE CENTRAL CONTROL COMPUTER/ENTERTAINMENT/CELL PHONE SYSTEM HAS DELAMINATES AND RANDOMLY SELF SELECTS BUTTONS. ON MORE THAN ONE OCCASION THE DISTRACTION OF CANCELLING PHONE CALLS AT ALL HOURS, ACTIVATION OF BACK UP CAMERAS AND SIGNALS THAT TELL THE VEHICLE TO DO WIERD THINGS NEGATIVELY IMPACT OF DRIVERS ATTENTION AND FUNCTION' THERE ARE LAWS ABOUT DISTRACT4D DRIVING AND THIS IS A MAJOR DISTRACTION. I HAVE TRIED TO RESOLVE THE ISSUE WITH THE MANUFACTURER AND THEY ARE UN RESPONSIVE. LOOKING AT THE VIDEOS ON HOW TO RE-LACE THE TOUCH SCREEN DUE TO MANUFACTURER REQUESTING OVER $1500 TO REPLACE BASED ON FALSE CLAIMS OF BROKEN/CRACKED GLASS IN THE SCREEN. WHEN THE REAL ISSUE IS THE TOUCH SCREEN MANUFACTURER FAILED TO USE AN ADHESIVE THAT CAN WITHSTAND THE HEAT WITHIN THE CLOSED CABIN OF A STATIONARY VEHICLE.

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

LOSS OF COMMUNICATIONS BETWEEN SEVERAL MODULES. ERRORS ARE TPMS LOSS OF COMMO AT ALL 4 SENSORS, NOT ABLE TO LOCK DOORS LOSS OF KEY FOB COMMUNICATIONS CAUSEING ENGINE TO TURN OFF. STATIONARY OR MOVING ON ANY ROAD OR SPEED. THESE BEGAN WHEN THE VEHICLE WAS FIRST PURCHASED OCT 2018.

WHEN PUTTING IN REVERSE THE BACKUP CAMERA DISPLAY GOES MULTI COLOR BLUR.THIS WAS ABOUT 20K THEN CORRECTED ITSELF WHEN PUT IN REVERSES THE NEXT TIME. DIDN'T THINK MUCH ABOUT IT. NOW AT 42 K ITS DOING IT MORE OFTEN. TOOK IT TO THE DEALER AND FRANK AT VACAVILLE DODGE TELLS ME ITS OUT OF WARRANTY, WHEN I HAD ALREADY SEEN THERE WAS A RECALL ON THIS PROBLEM. I WILL DOCUMENT AND TAKE PICS NEXT TIME IT DOES IT.

WHILE THE TRUCK IS RUNNING AND PARKED PASSENGER GETS OUT OF VEHICLE AND SHUTS DOOR CAUSING THE KEY FOB HAS LEFT THE VEHICLE WARNING ON THE DASH TO APPEAR. BUT THE KEY FOB IS CLEARLY SETTING IN THE CUP HOLDER IN THE CENTER CONSOLE AND HAS NOT LEFT THE VEHICLE. ONLY WAY TO RESET IS TO TAKE THE KEY FOB OUT OF THE TRUCK. THIS HAS HAPPENED EVER SINCE THE SEAT BELT MODULE WAS REPLACED. ON THE PASSENGER SIDE. HAS HAPPENED 10+ TIMES

PULLED OUT INTO TRAFFIC AND THE GAS PEDAL DID NOT PROPEL THE TRUCK AND I WAS ALMOST HIT BROADSIDE. IT'S LIKE THE GAS PEDAL TOOK 3-4 SECONDS TO SEND FUEL TO THE ENGINE AND CAUSED THE TRUCK TO JUST ROLL INSTEAD OF PROPELLING IT DOWN THE ROAD
