The hydraulic control unit (HCU) and the anti-lock braking system (ABS) module on our truck has been triggering the warning light and bell notification for almost a year & we have yet to be able to get this repaired as the part is supposedly back-ordered (for a year"!?!") We pull a fifth wheel with this vehicle and any sort of braking component issue is a recipe for a potentially disastrous incident on the road. We try not to drive the vehicle, but sometimes that isn't always feasible or practical. We are at a loss at this point.

The warning light comes on and then the traction control goes off and the cruise control will disengage all at once. There is also no trailer brake assist. This has been verified by a dealer in Columbus, GA. It is constantly going off and on. The warning light and the warning bell are a constant distraction to the driver. The truck was bought and within 50K miles it started. No warning.

The ABS sensor warning indicator comes on randomly. Normally every 45 seconds or so. The cruise control will not work when the warning triggers. The dealer replaced the sensor and the HCU units when the truck had @ 40k miles. Problem reoccurred within 6 months. The replacement parts have not been available now for 18 months and the dealer tells me they have no expectation when the parts will be available.

In 2020 my abs traction control warning light came on took truck to dealership. They replaced ABS motor. 1 1/2 year later the warning lights started to flash on which progressed into always on by April 2023. I had the truck at dealership for another recall and they tested and system. Dealership stated they would repair under warranty. I have been waiting 10 months for repair and they state they cannot order the part yet 3/2/2024 since they can only order so many per month and there is a long list in front of me. I have noticed a loss of braking power. And I am not able to use cruise control either

The Anti-Lock Brake & Electronic Braking System error caused the internal Trailer Brake system to shut off trailer brakes just like it shuts off the cruise control when warnings come up on the dashboard. The incident happened Aug 28, 2023 while following my son and my wife in a vehicle ahead of me. I had to change lanes to try to avoid something that suddenly came across in front of my vehicle. I applied the brakes and then the trailer acted like it didn't have any brakes fell over & was totaled. If this was in traffic someone could have been killed. The "Check Anti-Lock Brake System" & "Check Electronic Brake System" warnings started coming up intermittently as I drove my RAM 3500 Diesel truck starting sometime around July 2023. I drove to the local RAM dealer and told them about the problem. They acted like they had never heard of this problem and proceeded to check the error code and then stated they had never heard of this error before. They said they would check with RAM engineering on what needed to be done. They then said there were other similar RAM trucks with the same issue & that the parts were on back order. I finally got an appointment for the dealer to check my truck after sending an email to the Service Supervisor. After they checked my truck on August 16, 2023 they said that my truck needed a new Anti-Lock Brake Control Module. I had seen that many others on the internet blogs had stated that both the Anti-Lock Brake Control Module and the Hydraulic Control Module (HCM) needed to be replaced. I was then told by the service person that the Anti-Lock Brake Control Module would not be available for months (until sometime in December) and the Hydraulic Control Module (HCU) had no date of availability. They also checked with the RAM technicians at the dealership about safety driving the truck and towing a trailer until the part came in. They told me that only the Anti-Lock Brakes may not work so it would be safe to continue to drive it and tow a trailer.

Dealing with intermittent service brake system messages for over a year now. Light is constant now which means my ABS / anti skid/ and cruise control no longer function. Believe this is the ongoing HCU / ABS module known issue. Frustrating going into the winter months with such a heavy vehicle and loss of safety feature with no fix from Ram.

2018 Ram 3500 Laramie Longhorn, 64k miles, ABS/Traction lights on dash, intermittent, cancels cruise control and can't switch into 4WD. Dealer said it's a known issue and there is nothing they can do because there are no parts to order. I am a retired, disabled vet and I need help please. Thank You and God bless.

When operating the vehicle the Service ABS/Traction control light starts flashing and cruise control becomes disabled while driving. ABS and traction control becomes disabled. Safety issue! Advised the part will not be available until Feb 2024 and to operate vehicle as is.

When driving at Interstate speed of 65 MPH pulling my goose neck horse trailer the instrument panel started dinging and indicated "Service Electronic Brake System", "Service Antilock Brake System" and the Cruise Control stopped working. I slowed and continued home with warring alternation with "dings" every few seconds. I took vehicle to local Dodge Dealer (Blaise Alexander Lewisburg PA) on 08/10/23 who checked the truck and said I needed the HCU replaced. (Code: 0020-01) I had to wait a few days to get the part. Truck was returned to me on 08/15.23. Invoice Number CHCS26809. Total Cost: $843.75

Main Frame is cracking between the cab and bed of the truck. I took it to my local Ram Dealer in Chico Ca. Chuck Pattersons Ram they inspected it and told me not to drive it because it is unsafe to drive. The service manger said the frame did not crack from anything I did. It looked to him like it was a factory defect. They are welding across the top of the frame when mounting a bracket which is weaking the frame. This is where my crack developed from.They told me to contact Ram customer care arbitration as they should be able to authorize a replacement of the faulty frame. Without any explanation Ram arbitration denied the claim. I asked them to send me something in writing saying why they denied the claim and the person on the phone hung up on me. This is why I am contacting you.

my vehicle (Ram 3500 w/ a 6.7 liter diesel engine) has less than 38,000 miles and the ABS Hydraulic Control Module has to be replaced. I-??ve been told the part is on back order and cost to replace the unit is over $500 with another $400 plus to install this part. The dealership stated they could not place more orders until late March and since I-??ve been researching and found out that this is a larger issue that has been identified to Ram with a class action lawsuit for certain years and I think that this issue should be handled at no cost to the consumer.

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 with labor. Any questions, please call Bruce at Albany Chrysler. 320-845-2801. This is an intermittent issue, that comes and goes.

Infotainment screen is delaminating causing it to randomly dial and call numbers, cannot control the climate control, cannot adjust settings, and renders the navigation unusable.

ABS pump module failed with vehicle under 25K miles. Pump failed prematurely and failed while I was driving, disabling my ABS brakes. The ABS lights and check engine light did light up, it has since been replaced and there is no recall on this issue. Seems to be a common issue with FIAT Chrysler cars.

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 down into other controls such as the Exhaust Brake, Trailer Brake Controls, and other physical buttons. It is my belief this is becoming a safety issue as the delamination is causing phantom key presses on various systems including setting volume of audio at 100% randomly.

On multiple occasions the shift arm would not move while vehicle was in park and foot brake was depressed. Seemed like the safety device that prevents an automatic shifting arm from slipping out of park without brake depressed did not release. Vehicle was on flat level ground, the only way to correct problem required shutting vehicle off and then restarting. Once this process was conducted the safety device operated normally. In the three years of ownership this has happened three times and each time my resolution worked.
