2018 RAM 3500 Electrical System Problems

ABS Control Module and/or Wheel Speed Sensors is causing the abs warning light and traction control module light to go on and off intermittently for over a year causing the cruise control to not engage or to disengage…

"Service electronic braking system" and "service antilock brake system" are popping up on gauge cluster at highway speeds. This is a random event that started at about 35,000. The system shuts on and off constantly with chimes and alarms to “Service electronic braking system" and "service antilock brake system". I contacted the dealership by phone, and they said they know about this issue but there is no Recall yet and it’s not covered under powertrain warranty; they advised it needs to have the ABS pump and control module replaced. I have looked on the internet and see several thousand complaints for the exact same issue. To me this seems like a life/safety issue that is being ignored Stellantis / Ram.

HCU unit failing. Keeps throwing service abs, and service electronic brake controller. On off on off on off non stop constantly the whole time truck is almost undeliverable Part is unavailable due to supposedly back ordered. Been told part is known issue and that a recall should be done but it’s not. Hydraulic control unit. So driving a one ton truck with failing abs, traction control with no delivery date of a part that is junk.

HCU Issue: The ABS light coming on is the lightwill come on for two second and go off at times, through the diagnostics of the code C0020-01. It is a general electrical failureto the hydraulic control unit. The unit is replaced separate from the ABS moduel th HCU needs to be replacedfirst. In some cases, the ABS module that is bolted to the HCU needs to be replaced and programmed as well. The HCU needs replacement first. The total estimate is $1010.00 with labor. Any questions, please call Bruce at Albany Chrysler. 320-845-2801. This is an intermittent issue, that comes and goes.

2018 Ram 3500 - ABS system/Electronic braking system failure at 5583 miles. ABS/traction control and service electronic braking system display on dash, also audible chime with cruise control inactive. Took to dealership for diagnonis and code C0020-01 is active. Reccomended replacement of HCU which is common for these vehicles. Truck is out of warranty and estimate is $1080 for repair, which does not include the $301 I spent on diagnostics. There needs to be a recall on these Chrysler HCUs as they are a known issue and related to the braking system. Why do I see recalls on items such as malfunctioning tailgate latches but not braking systems?

ABS and Traction Control lights and DIC alarms came on while driving. They stayed on for a few minutes then went off. Also the service trailer brake system message came on. This has happened several times now turning off cruise control too. I reseated all fuses and went for two weeks before it started happening again. Happens sometimes as we go over expansion joints or hit potholes while driving at highway speeds. I notice several other reports of this here at NHTSA site and various RAM forums across various RAM years.

ABS and EBS sytem is shutting on and off on highway at speeds. This is a random event that started at about 20,000 miles then went away for about 6,000 miles then came back at 29,000 miles whil on a 1,500 trip and is now not going away. The system shuts on and off constantly with chimes and alarms to "service ABS/EBS. I have the truck at the dealership and they advsied it needs to have the ABS pump and control module replaced. I have looked on the internet and see several hundred complaints for the same issue. The delaer says this is not a recall and is not covered by warrenty. To me this seems like a safety issue that is being ignroed by Chrysler corp / Ram. They are looking at the numbers and not enough people have been in accidents to justuify the cost of a recall....

The ABS Anti lock lights came on and says check Electrical Brake System. Dealer said The ABS anti lock brake pump assembly was bad and it was on me to replace it. This is a big safety Issue to me. I got a 2018 3500 ram and paying big money for a truck and my safety, there should be a recall before some people get kill.

The contact owns a 2018 Ram 3500. The contact stated while driving approximately 35 MPH, the contact observed that the check engine warning light was illuminated and the coolant temperature warning light was also illuminated. The contact pulled over safely and turned off the vehicle. The contact drove the vehicle to a dealer where it was diagnosed and determined that the thermostat, coolant sensor, and air intake heater relay needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V798000 (Electrical System) however, neither the VIN nor the vehicle year was included. The manufacturer had been informed of the failure. The failure mileage was approximately 67,000.

ABS and Traction control pump system electrical failure. Went to a Dodge Dealer and had the system read due to light coming on and off. Originally started around 38,000 miles on the truck. A code came up C0020-01. ABS pump motor control electrical failure. Researched on the net. Seems to be a big issue from 2013 on up on trucks. Chaffing wires? Pump failure? Dealer said the ABS Pump could Possibly be bad. Wondering if there is a safety Recall or will have one. I have my truck scheduled for repair next week. Estimated cost of $700.00 according to service department.

The warning chirp occurred and the ABS and ESC lights came on the first two times. The incident happened so quickly I could not clearly determine which warning lights illuminated. On April 18 with just over 39,000 miles on the vehicle the chirping alarm and the ABS and ESC light illuminated. In addition two warnings appeared in the dash: "Service Antilock Brake System" and "Service Electronic Braking System." The warnings happened multiple times per minute in some cases. Other times the vehicle would go for many miles without the warning. Every time the warning chirp was heard the cruise control would disengage. I did not notice any problems with the brakes of the truck. In researching the issue I learned that many people are having this problem. I contacted Ram and they directed me to a dealer who diagnosed the C0020-01 fault code and that the hydraulic control unit (HCU)...

Uconnect screen delamination causes phantom button pushing while driving down the road. This causes random buttons to be selected and for things to start happening while driving. Driving distracted is dangerous driving. It will randomly call people, including using the SOS functionality. Making non-emergency calls to the emergency line is unacceptable. Once while driving, it turned the radio on and my volume was cranked up. I almost crashed into the car next to me because it scared me half to death. This is a known issue from what I've been reading on RAM forums and almost always shows up outside of warranty. The manufacturer should be held accountable for this to prevent future wrecks, distracted driving, and unnecessary SOS phone calls.

Service electronic brake system with the traction control light lit. Seems to be a common occurrence

8.4" Uconnect display is now bad. It changes every mode of truck as a "ghost touch" and is a severe distraction while driving-climate, music volume, stations, cameras, sensors. It is a widely known problem involving the screen digitizer and nearly every FCA vehicle having the 8.4" screen fails-Ram, Dodge, Jeep, Chrysler.

UConnect 8.4 Screen Delamination - The integrated radio/communication/vehicle functions module screen is delaminating on a vast number of vehicles. The repair according to RAM dealerships is a complete replacement of the screen and the controller at a cost of nearly $2000 per vehicle. While initially most believe this to be a radio issue the systems are integrated to multiple functions of the vehicle including: front and rear cameras, front and rear parking sensors, ride height controls, HVAC controls, seating controls, and a number of other systems. It also includes access to a number of phone systems including emergency calling. Due to the integrated nature of this equipment a major recall should be conducted on affected systems and also a forced reimbursement to owners of vehicles that have had to pay out of pocket for repairs or diagnostics. In addition, the delamination seems to be causing a leaking substance to drip...

The 8.4 u Connect Radio is delaminating and randomly calling people and switch to things on the screen randomly it’s a safety issue because it’s a distraction for the driver and could cause other electrical damage I haven’t taken it to a dealer because I already know the answer it’s up to me to replace it until the company takes ownership of there problems

The uconnect 8.4 navigation screen is delaminating. This could become a safety issue if the screen continues to melt and drip glue on the traction control, trailer brake control, parking sensors, as well as can be distracting to the driver if the screen changes on its own. It can also cause the rear view camera to turn on and cause a motion picture to be displaying while the vehicle is in constant motion. The screen has been inspected by a third party and is in need of replacement which costs over $1000. The cause is a faulty part that is not made properly and causes it to prematurely separate from the lcd screen.

The contact owns a 2018 RAM 3500. The contact stated that while driving at various speeds, the vehicle experienced random electrical failures related to the MY TOUCH home screen. The contact stated that the vehicle would independently call random phone numbers including the SOS help button, as well as the local police station’s number stored in the contact's phone. The manufacturer was notified of the failure and informed him that because his home screen had started to delaminate, this failure was a known result on several model vehicles. The contact also called the dealer and they acknowledged that the failure was a known issue and was given an estimate for the repair. The vehicle had yet to be repaired. The failure mileage was approximately 53,000.

The abs system has failed on my truck and many more possibly by a dealer defect and no recall as of now. When the abs warning light comes on it also puts up a warning light for the electronic braking system and you aren’t allowed after that to set the cruise. Anytime you hit a bump or turn the wheels or just randomly at any given time the lights come up on the dash and it chimes which will drive anyone nuts. With the electronic braking system not functioning properly could potentially lock the brakes up on the truck in my opinion knowing how it functions. Which in my opinion is a safety hazard. Also I might add that taking my vehicle to my local dealership is a complete waste of time as the diesel mechanic up there is terrible at his job. He has misdiagnosed two of my trucks...

8.4 inch Uconnect infotainment screen is delaminating. The digitizer screen is separating from the LCD screen from an apparent manufacturer defect. This screen controls backup camera, secondary heating and cooling defrost function. This is a safety issue as the screen becomes non responsive or ghost touch inputs start to randomly change settings in the vehicle.

THIS IS A KNOWN CAUSE BUT DEALER WILL NOT REPAIR BASED ON MILEAGE OF TRUCK WHICH IS 45K. THE COST IS OUTRAGEOUS TO HAVE REPAIRED AT DEALER.

TL* THE CONTACT OWNS A 2018 RAM 3500. THE CONTACT NOTICED WHITE POWDER COMING FROM THE VENTS WHEN THE AIR CODITIONER WAS ACTIVATED. THE VEHICLE WAS TAKEN TO REAGLE DODGE (ROUTE 512 BANGOR, PA 18013, (610)-863-6900) WHERE IT WAS DIAGNOSED THAT THE EVAPORATOR COIL FAILED PREMATURELY AND CAUSED A CHALK LIKE DUST TO BLOW INSIDE THE VEHICLE.

THE CONTACT ALSO STATED THAT THE FAILURE WAS EXERIENCED IN THE 2014 AND 2015 MODELS. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 6,000.

WHEN TRYING TO ACCELERATE, WHEN I HIT THE THROTTLE PEDAL THERE'S A DELAY OF AT LEAST 5-10 SEC BEFORE TRUCK RESPONDS AND STARTS ACCELERATING. VERY DANGEROUS WHEN SWITCHING LANES ON HIGHWAY. I'VE READ ONLINE THAT THERE IS A LOT OF OTHERS THAT HAVE THIS SAME ISSUE WITH VEHICLE LIKE MINE.

INTEGRATED BRAKE SYSTEM FOR TOWING TRAILERS (ITBS) DOES NOT WORK. SAFETY HAZARD AS THE TRUCK CAN NOT STOP THE 150000 POUND 29T ARCTIC FOX 5TH WHEEL. AFTER 4 ATTEMPTS DODGE GAVE UP AND SAID THE ITBS WORKS AS DESIGNED. THE 5TH WHEEL WAS CERTIFIED THAT THE BRAKES WORK WITH OTHER TOW VEHICLES. NOT WITH OUR RAM 3500 WHICH IS RATED TO TOW 22000 POUNDS WHICH IS A SAFETY HAZARD. WE ARE UNABLE TO STOP THE TRAILER IN AN EMERGENCY OR UNER NORMAL DRIVING CONDITIONS USING THE ITBS.
