CB4 Recall Some (2017-2018 MY Ram xxx) vehicles may have been built with a brake hydraulic control unit ("HCU") that is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss. Been dealing with this issue since the recall got initiated back in November 2024. I call Mopar every month to check on the status and still no parts available. I haven't had any brake failures in my truck or scares, but whoever has this issue has to understand how annoying the constant chime is. Can't use cruise control and worst thing is if you are considering selling your truck outside of a Ram dealer, they won't take it in because of the open recall and privately, who would...

ABS TRACTION CONTROL LIGHT HAS BEEN ON/OFF SINCE 2020. Can't drive on snow ice due to traction control abs 4-wheel drive doesn't work correct. I almost hit the divider/wall on Interstate 30 on 01/28/26 due from poor braking.

The transmission is slipping and making clunking noises and I'm worried it fails while driving it could be a safety issue. I noticed other people online mention the same problem. This should be a manufacture recall to get repaired not a consumer.

Constant cycling of ABS and Traction Control lights with tones. Causes ABS, Traction Control and cruise control failures with persistent tones and lights. Parts not available after 12 months of open recall.

unknown my brakes had a recall on it for the hydraulic system my transmission gave signs of going out while i was driving it would rev up and then would go when i would increase speeds

On the highway towing a horse and the transmission stopped working right. Couldn’t keep up to traffic only had one gear.

While driving the truck seems to jolt when trying to get into the next gear or it seems to be slipping a gear. At times the truck will stay in a gear too long and not switch over in a timely manner or it it will switch gears too quickly. The dealership and another quote says it seems it could be the transmission valve plate and solenoid all the way up to a new transmission is needed. The truck has only 53,000 miles and maintained routine oil Changes and maintenance. I would like to see if there is a recall or one needed because I have never owned vehicle that needed a transmission at 53,000. That’s insane.

If I hit a bump it sets off the lights for the abs and the traction control and I have to run my truck with the traction control off if not my truck won’t shift right if I’m going 60 or above also had to get the transmission replaced

The contact owns a 2018 Ram 2500. The contact stated while driving and attempting to shift from third gear to a higher gear, the engine revved and the vehicle failed to respond as intended. The contact pulled over to the side of the road, turned off and restarted the vehicle, and the vehicle responded as needed. The contact stated that the failure had been recurring while driving. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. Additionally, the contact received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The contact stated that the ABS warning light was illuminated. The local dealer was contacted. The vehicle was not repaired. The contact stated that the manufacturer had exceeded...

Towing my camper with my family in the mountains during Memorial Day weekend. It was rainy. My brakes failed me SEVERAL times as well as my traction control. To say it was scary is an understatement. I don’t even want to use the truck anymore. I have had several chats with ramcare as well as a call to my dealership with zero resolutions. Someone is going to get hurt or worse. The HCU no longer works.

The approximate failure mileage 125,000. VIN tool confirms parts not available.

While towing a heavy load of approx. 16,000 Lbs. uphill steep grade during 100 degree temperature at low travel speed but high engine RPM a load boom came from the engine compartment. Upon inspection the fan shroud had made contact to the fan and caused severe damaged to the cooling system rendering the vehicle disabled until repairs could be made. This occurred about 30,000 miles ago however the current fan shroud has also failed under normal use. If the failed shroud damages the serpentine belt steering and breaking will be jeopardized which could lead to an accident!

Truck will not shift and drops out of drive leaving you helpless

The ABS brake warning lights are on all the time. I have no cruise control. There are times when I can't even shift my vehicle into gear. I will be checking to see if I even have 4wd with this light on. But, haven't tried it since the lights have been on.

The contact’s husband owns a 2018 Ram 2500. The contact stated that while driving at various speeds on several occasions, the vehicle started shaking and lost motive power. The contact stated that the message "Transmission Hot" was displayed and the check engine warning light illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was then taken to an independent mechanic where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 79,790.

Timely as my 2018 2500 seems affected. I've performed no troubleshooting but it is extremely intermittent, either the Service the ABS or Service the Electronic Braking System(s). Usually, a bump in the road makes it come and another turns it off. Sometimes it happens so quickly, only the message and traction control disabled light comes on, sometimes only the chime comes in. Sometimes the message stays up and the brake warning and traction control light comes on, sometimes for a few minutes, sometimes a couple of seconds. Always goes away with an ignition cycle. If it's on long enough. For some period of time, it came in when I turned the truck on and off when I released the parking brake. Annoying.

The abs module has gave me issues and now has gone completely out causing no brakes and while it was having intermittent issues causes no cruise control and causes transmission issues which is another thing the transmission has went out again after this is the 3rd time replacing at around 10k everytime

Traction control light and ABS light come on and go off intermittently will cancel my cruise control.A warning ding accompanies this.It does this frequently while driving.Electronic braking warning comes on the dash.

I purchased this truck new in 2018. I soon started having problems with very hard shifting and slamming into gear. It has been to the shop and diagnosed and continues to do it. They cant seem to fix it. My ABS lights and alarm are sounding non stop. This happened within 5 miles of my warranty being up. I did diagnostics and they wont cover it and want to charge me 1500 plus i have to wait 8 months for the part. This is an ABS issue and a safety issue! I also get the DEF failure notice telling me its going into limp mode. This has happened multiple times. I still only have 36k miles on it. I was told this ABS issue was now covered and the factory is doing extended warranties based on these problems. But the dealership says they know noting about it and that i...

This truck has had two major REAR-END repairs. After the last one it vibrates. Several sets of tires and even a new set of rims and it still vibrates. NONE of the dealers can locate anything.I took it to a shop that has vibration detection equipment. Their results show the issue is in the rear end. I get no resolution or help in resolving the issue. I have been out a lot of money on this truck due to odd break downs and issues that Ram refuses to acknowledge. I am beyond sick of this. I paid a lot of money for this junk.

The issue with the Electronic Braking System and ABS has worsened. The two warning lamps are almost constantly on, or rapidly come on and go off rapidly. If I'm towing a trailer, all braking is lost momentarily - brake pedal to the floor - including the trailer brakes. The trailer brakes do not return until an ignition cycle, if the warning lamps stay off, that is. The dealer says no parts are available, but won't even take it in for troubleshooting or attempted repair. This truck scares me. This has been an issue for about two years and 20,000 miles.

ABS and traction control lights came on. Brought to my mechanic and they spoke with Dodge who started they put a freeze on selling the parts and currently have no fix.

The truck would not go above 40 mph, then the transmission began slipping, slowing the truck down to 20 mph. This happened while pulling my camper. This put us at risk of collision. The truck is going to the dealer on Weds, Aug 14. The vehicle has yet to be inspected, but will be at the dealer on Aug 14. No warning lights.

Hi, The ABS System shows Service Antilock Brake System at the display, It comes and go so I assume that it is an intermittent issue, it does stays for hours or days and go on ad off during the whole drive, definitely is an issue. It allow the brakes to preventing locket when brake on certain circumstances. Had an issue on a wet pavement and have to handle to avoid crash with other vehicle cause the tires got locket and the truck slipped on the pavement for a considerable amount of feet's. Dealer inspected and replaced the module under warranty when I bought the truck and told me that it has to be replaced again.

For the second time since the vehicle's purchase in 2019, the Antilock Braking System is flashing an intermittent error stating that the Antilock Braking System needs to be serviced. When the system flashes the error, the antilock brakes, cruise control, and stability control become disabled. The error sometimes will clear itself, and then immediately return a minute or two later. Three years ago I had this same issue repaired once before under the vehicle warranty. At that time, I was told the Hydraulic Control Unit for the ABS system had failed. Now, without warning or reason the system is failing once again and RAM refuses to replace this defective part. Through an online investigation, I have discovered that thousands of Ram owners are experiencing the same defective part and circumstances. Without proper functioning brakes, antilocking brakes and stability control, the vehicle cannot be driven without great risk to the vehicle's...

When taking off initially with the truck sometimes within the first 30 seconds of moving there is two yellow lights that come on the dash, while the center text window displays service brake system. The stored MIL code is C0020-01. Also when going over bumps in the road the message will also return. Sometimes it stays on, and I do not have the ability to use cruise control. One time I was driving on the freeway and the surface was wet, as it had been raining. I needed to slow down rapidly because there was a sudden change in traffic. I went to hit the brakes and the truck had locked up the wheels, and then after the same lights and text were displayed.

Loss of power/turbo. I was hauling a heavy load when I had a loss of turbo power on highway. Causing my truck to loose mph up a hill and almost getting struck by a semi vdd into my trailer. Check engine light is on and turbo don’t kick on anymore. I haven’t had the money to fix the problem but I’m certain it’s the turbo/turbo actuator.

Brakes when depressed do not pull equal. No cruise control. 4 wheel drive is not working properly. Traction control not functioning properly Have brought vehicle to a garage. Abs/hcu unit is the problem.

I purchased the truck used from Kunes dealership in Sterling Illinois with about 80k miles. It shifted harder than I was use to in low gears, right off the bat. I was advised everything was good with it at the oil changes and inspections. In June 2023 I noticed it would not shift into reverse and without yanking in the shifter. It lunges once forward while in park in my driveway. At just over 100k miles the check engine light came on. Coded as needing a new transmission. Also in September 2023 while driving it a brake warning light flickered in and went off. Haven’t seen it again. I think there are problems with this truck. The shifting slow and hard in low gears seemed odd and I worried about proper acceleration to avoid a rear end collision. I understand very little about vehicles but this one has been doing...

Bought secondhand at auction with low mileage. Had checked outbytrusted mechanic, all was well. Vehicle records showed brand new transmission on truck. Transmission slipped after service. From July 2022 to today (December 2023) have had to replace transmission FOUR TIMES at great expense. Went to dealership and found no recall notice, they are offering to purchase truck for $7500 cash. Purchase price was approximately $33000 plus about $15,000 in repairs/new transmission replacements and cost of rental vehicle in the thousands as this was a truck purchased for a business. Please issue a recall for this vehicle! This has put a huge dent in our small business and we still don’t have a functional truck!

The ABS control pump motor is malfunctioning causing loss of the anti lock braking, four wheel drive, and cruise control. The dealerships have no ability to get parts to repair and they have been on back order indefinitely.

The contact owns a 2018 Dodge Ram 2500. The contact stated that while driving at 55 MPH, the brake pedal felt firm, and more pressure needed to be applied to the pedal in order to stop the vehicle. The Abs and electronic brake warning light was illuminated. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the failure was due to a faulty ABS module and HCU, both needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and determined that they did not have the parts for repair. The failure mileage was approximately 40,438.

The gear shifter on my truck separated in two. This has been a past problem with this vehicle and was subject to a recall for all G56 equipped ram trucks from 2015-2016. However, the problem still occurs and the replacement part is just as faulty. Previous recall is under Customer Satisfaction Notification T-13. However, these recall does not cover 2017-2018 trucks, despite the shifter being just as faulty.

My vehicle has intermittent ABS/Traction Control/Service Anti-Lock Brake warnings. Upon trip to the dealership they notified me that I had codes for active wheel speed sensor and a stored Anti-lock Brake Module fault. Upon repair of the Wheel Speed Sensor, I had a reoccurring fault of the same and all ABS/Traction Control/ Service Anti-Lock Brake warnings and the same wheel speed sensor fault. They informed me that they could not order the ABS Pump Module as it was on engineering hold because of an investigation by NHTSA. Please make these people recall the ABS systems on these vehicles as when I look for information it is happening to hundreds if not thousands of trucks. My truck has 125,000 miles on it and has been WELL kept, and Mopar/FCA will not even sell us the parts to make our vehicles safe again. Currently due to the fault I have no cruise...

The manufacturer was not made aware of the failure. The failure mileage was approximately 111,223.

INTERMITTENT FAILURE OF ABS/HCU RESULTING IN NO ABS, CRUISE CONTROL, OR TRACTION CONTROL. UNABLE TO FIND THE PART IN QUESTION, DEALERS WANTING NEARLY $2000 FOR REPAIR ON UNACCEPTABLE TIMELINE. UNABLE TO HAUL SIGNIFICANT LOADS WITH TRUCK (I.E. CAMPER OR EQUIPMENT/TRAILERS). DOING RESEARCH I FOUND THAT THIS IS A VERY COMMON PROBLEM WITH THIS TRUCK AND NO RECALL WAS EVER ISSUED. HCU PARTS ARE NOW RESTRICTED AND EXTREMELY EXPENSIVE IF ONE DOES MANAGE TO FIND ONE. CLASS ACTION LAWSUITS INITIATED AGAINST CHRYSLER IN CALIFORNIA. THIS ISSUE HAS BEEN KNOWN ABOUT FOR YEARS NOW AND SHOULD BE MADE KNOWN TO ANYONE THINKING OF BUYING A RAM. I LOVE THE TRUCK BUT IT IS UNSAFE AND INCREDIBLY DIFFICULT TO REPAIR AT THIS TIME CAUSING SIGNIFICANT HEADACHES FOR MY FAMILY.

abs not working for a year now. dodge has no parts to fix issue not safe to drive and should be a safety re-call on hydraulic control unit.

I revered my truck up a slight incline in reverse in 4 wheel drive. After I stopped in reverse I removed my vehicle out of 4 wheel drive back into 2 wheel drive. I put the transmission in park and removed my key. I unloaded items from the back of the truck. During this period the truck began to move forward down the incline building up speed as it went. It struck a tree stump and came to rest there. No one was in the vehicle and I confirmed when I got in it was still in the parked position. It appears the vehicle never engaged the transmission to the parked position.

Abs/traction control lights come on and disconnects the cruise control dangerously wen pulling a trailer, code is c0020-01 this is a very common issue with these trucks parts unavailable, I’ve talk to many other owners with same issues please address the problem before someone gets hurt thanks.

The contact owns a 2018 Ram 2500. The contact stated that the vehicle had failed to start up after multiple attempts. The contact also discovered that the gear shifter would move while the engine was turned off and without depressing the brake pedal. The contact discovered that the brake transmission shift interlock was defective. The vehicle was initially towed to an independent mechanic who informed the contact that he did not have the capability to repair the vehicle. The vehicle was then towed to a dealer where the part was replaced. The manufacturer was notified of the failure. The vehicle was repaired. The failure mileage was approximately 80,000.

The Service ABS light come on, around 32,390 miles just out of the 3 year/36,000 mile warranty! The cruse control no longer works! The traction control light is on with the ABS light! Beeps on and off and on and on very annoying!!! Had the truck scanned by my local Mechanic. ANTILOCK BRAKES C0020-01 ABS PUMP MOTOR CONTROL-GENERAL ELECTRIC FAILURE-STORED. The truck is available upon request.

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.

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.

Our truck has less than 25000 miles on it and the transmission has been consistently slipping in high gears for about the last 3000 miles. Our friends had the same truck with 46000 miles and their transmission just failed. We have read about many instances with the same transmission going out prematurely. Our truck is available for inspection. There have been no warning lights in the truck.

The contact called inquiring about a Law Enforcement vehicle (2018 RAM 2500). November 2020, vehicle shut down while traveling up a road. “Lost all PCM communication.” Instrument cluster was on, but vehicle would not start, multiple warning lights were illuminated. The vehicle was not drivable. Towed vehicle to Flower Motors (RAM) in Montrose, CO where it was diagnosed with needing a PCM replaced. The vehicle was repaired, however it continued to experience the same failure. July 2021 while the same Law Enforcement Officer was traveling at 30 mph in a 35-mph zone into a sharp right turn, the vehicle "lost all the PCM communication". The Law Enforcement Officer could not stop, due to no brakes and had a difficult time turning the vehicle. The Law Enforcement vehicle crossed the road into the oncoming lane of traffic and off the shoulder into Sagebrush. The Law Enforcement Officer was able to steer...

The contact owns a 2018 Ram 2500. The contact stated that the vehicle was repaired at the dealer under NHTSA Campaign Number: 20V036000 (Power Train) however, the failure occurred after the recall was repaired. The transmission shifter would not shift to drive after the vehicle was parked. The transmission shifter cable disconnected from the transmission, causing the vehicle to not perform shifts intended by the driver. Additionally, the gear shift lever position on the dashboard did not match the actual transmission gear. The vehicle was towed to the dealer. The vehicle was not diagnosed nor repaired and remained at the dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 30,000.

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.
