2018 RAM 3500 Vehicle Speed Control Problems

Slide off road while braking. Braking problem due to recall, Manufacturer Recall NumberC4B / NHTSA Recall Number24V-896. Recall was to be fix 1st quarter of 2025, Now 2026 still not repair solution.

There is an open recall (C4B) for my Ram truck. The ABS light and "Service Brake System" light and message are currently displayed on the truck's dash. I contacted FCA about a year ago and told them I have an active issue. They said they placed me on a priority wait list but the remedy is not available yet. It is unacceptable for them to not have a remedy ready for an 8 year old truck when the issue was known about some time ago. I would appreciate if NHTSA or other government agencies would put pressure on FCA to repair this issue as owner's and other motorists lives are on the line if faulty equipment is forced to drive on public roadways. Thank you

Since January 2023, my truck stability control system has been disabled related to CB4 NHTSA 24V-896 recall. TWO years! I can't sell the truck like this & I have no idea when it will result in an accident. Stellantis needs to be held accountable. Every contact with them results in a response of waiting for parts. I've had no choice but to drive another 18000 dangrous miles with this vehicle. This is unacceptable.

Almost got into a wreck because my ABS failed. I was going down the interstate with my cruise control on and my abs and traction light came on. My cruise control.immediately stopped working and I was almost rear ended. I called the Ram dealership and they said they have no time frame of when they will have parts in to fix it under the recall. Does someone have to die before Ram will start fixing these abs units. The recall has been out since Nov 2024. They need to be held accountable or buy back all 2017 and 2018 rams affected by this.

No solution for the antilock breaking system,causing drivability issues and loss of traction control,abs and control on numerous occasions.

Traction control and ABS work intermittently. Ram sent out this notification for recall concerning stated problems but state there is no fix at this time. They continue to state there is no fix. This is a safety issue and you are not forcing them to repair. They are dragging their feet hoping it goes away. DO SOMETHING!!!!

The Hydraulic brake control has been a recall with no replacement part available for over 2 years and this causes many safety functions to not work properly including trailer braking. They have made parts for a 2500 model but neglected to fix the 3500, 4500 and 5500 models. They will fix it with another faulty sensor and still expect owner to pay a 1700 repair bill even though it’s a recall. It’s ridiculous on the time this is taking.

24V-896. This recall is a safety issue known for years. There is still no action from the manufacturer! I was extremely lucky to avoid a serious collision. The only solution the manufacturer offers is to authorize a dealer to replace the parts with another secondary market provider part, but they won’t cover the cost or warrant the replacement. How many YEARS do I have to drive an unsafe vehicle?!!!

Audible alarm, warning lights on dash. Come on and off. No cruise control available.

Continually gets abs stability error. Unit has been replaced once less than year ago. Comes on if vehicle sits or hits a bump. Lose of abs cruise and continual dinging.

The service electronic braking system and service abs system continues to ding and pop up on screen. Cruise control will not work either.

ABS-Hydraulic Control Unit failure, pump motor control electrical failure. Confirmed/ Diagnosed by dealer. Messages on dash info screen: "service electronic braking system", "ABS failure", warning lights : Traction Control and ABS failure. Safety risk when warning message appears: ABS, Traction Control and Cruise Control are non- functional.

my traction control, cruise control unavailable, and warning light to service abs electrical system. Dealership said the hydraulic control unit has to be replaced.

My 2018 Ram 3500 DRW truck for no reason started throwing dash warning lights intermittently after 60,000 miles. The warning lights activated on the dash were for ABS and Traction Control, with an annoying ding when they appeared. The center dash light stated "Service Antilock Braking System. Additionally, when this occurred the cruise control did not work. The warning lights were intermittent and just occurred at any time and disappeared as quickly as they showed up. This would happen for miles and for no apparent reason just stopped for a period of time. I took the truck to the dealer who informed me that its a known issue with the ABS HCU and the truck would be safe to drive but I would not have ABS and cruise control would not work. They also said parts were not available and could be a six month wait. They also told me...

Service Electronic Braking Service and Service ABS/TRACTION CONTROL. This is intermittent. When it happens Cruise control, 4 wheel drive and abs doesn't work. Happens when I'm towing my camper or not. Trailer brakes won't work when this happens. Hundreds, maybe thousands of complaints about this on Ram forums. This problem occurs no matter what the speed is. It even happens while sitting still.

Hello, I have an issue with the ABS Braking system on my 2018 RAM 3500 with only 50K miles on it. The lights are constantly coming on and off telling me that my ABS system needs servicing. this has been going on for two weeks. I was able to troubleshoot the problem and it says that my ABS pump and Module needs replacing. I was going to replace myself and when I ordered the parts from MOPAR they told me it was a 2 month lead time which I thought was unacceptable being such critical components to a vehicle. This week I almost rear ended another vehicle because the brakes failed. I have been online reading about the stories of these same complaints from many RAM & JEEP owners. How this company is getting away with safety issue is beyond me as this is going back to 2023, how are...

1. The specified vehicle has intermittent ABS/ Brake Hydraulic Control module error. The vehicle is available for inspection upon request. 2. Error causes ABS and Cruise Control to be disabled while in motion as per warning messages displayed on instrument cluser and audio annunciation. 3. Driver and passenger were endangered due to ABS malfunctioning intermittently **while in motion**. I have reproduced the problem by causing a wheel slippage on wet pavement. This will cause the otherwise intermittent problem to be asserted with corresponding error messages/notifications to be displayed on instrument cluster. 4. The specified vehicle has NOT been inspected at a Ram dealer; however, the problem seems to be well-known on 2017-18 Ram 2500's and 3500's given the amount of Youtube videos on the topic as well as the amount of discussion on online forums such as [XXX] . 5. This 2018 vehicle has approx 43000 miles on it. The...

THE ABS BRAKES YES IT IS AVAILABLE FOR INSPECTION BY NOT HAVING ABS BRAKEING WHEELS HAVE LOCKED UP HAVE NOT HAD DEALER CHECKIT HAD A MECHANIC PUT ON COMPUTER FOR CODES NO TRUCK HASN'T BEEN INSPECTED BY ANYONE ELSE BUT THE MECHANIC WARNING LIGHTS HAVE COME ON AND OFF A NUMBER OF TIME AND LATELY MORE OFTEN IT STARED ABOUT A YEAR AGO TOOK IT TO DEALER THEN BUT WASN'T REPAIRED PROPERTY

Intermittent loss of anti-lock braking system and cruise control. code C0020-01 ABS pump failure. First occurred at approx. 47,900 miles.

I started getting an intermittent error code on my truck with only 36k miles on it. the traction control, abs and cruise control wont work when the service electronic braking system code is present. I have done a lot of reading and this seems to be a very common issue with the 2017 and 2018 ram trucks. It is so common that I called my local dealer and the part is on back order for months. I am getting very close to taking a long road trip with a 20ft trailer, which is the reason I purchased this truck. Now I cant even get a replacement part, that is a known issue and I was quoted $1100 for it. Braking system seems to be a safety issue, why isn't ram doing something about this issue!

On September 8, 2024, I started getting intermittent ABS and Traction Control light with “Service Electronic Braking System”. Code C0020. When the light is on I lose cruise control. There is no specific condition that will cause the light to come on; i.e. bumps in the road, a certain speed, or setting at idle. The first instance of the light coming on, I was turning around in a parking lot, less than 5 mph. This cannot be associated to normal wear and tear. THIS IS A SAFETY ISSUE AND MUST BE A RECALL!!!

Intermittent chime and warning that anti lock brake needs servicing. Cruise control does not work when notice is displayed and chiming. warning comes and goes randomly After researching this problem it appears that this is a regular problem on this year ram truck I will report and take to the dealer if problem remains.

We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes...

A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 —> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the NHTSA to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn’t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.

The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.

We receive a ABS/ECS, electronic brake control warning intermittently. This also makes the cruise control shutoff. We had the ABS control module replaced once at roughly 12000 miles under warranty but it now is giving the same warnings and the truck currently has 22000 miles on it. My dealer stated this was a known issue and stated it’s fairly common on my model truck

I have a 2018 RAM 3500 with ONLY 20,000 miles on it. ABS and HUC critical parts are faulty, and I have no way to even purchase one until a recal is issued. Class Action Says 2017-2018 Ram 2500, 3500 Equipped with Defective Anti-Lock Braking Systems. No current part that resolves this issue. Ram 2500 and 3500 pickups are unsafe because they’re equipped with defective hydraulic control units (HCUs) and anti-lock braking systems (ABS). RAM knows about it and has ALL the modules on engineering hold. These parts have not been available for almost a year. No antilock brakes. No traction control. No cruise control. 4X4 four wheel drive system is locked out and cant be engaged after this warning occurs. Here's what they are telling customers who have filed with them about this. Good Morning Mr xxxx, As of 06/26, No new update Part: 68228991AD Module Order: xxxx Per...

Vehicle produces code C0020-1 ABS pump motor control failure, vehicle disengaged cruise control unexpectedly causing rapid deceleration. Dealer states ongoing problem with 2018 Ram 3500 HD trucks

ABS system - flashes on and off dash, ABS has been inspected by dealership. Dealership said, could replace ABS but it could very likely have the same issue due to part malfunction. This malfunction causes- no cruise control, no traction control, sounding and lighting up on dash constantly.

ABS/Service Electronic Brake Control and Cruise Control lights constantly flash and chime while driving. Have been told that replacements parts have been on back order for over a year now. Any help will be appreciated.

Antilock brake warning light that says service antilock brake system comes on often if you hit any bump or rough spot. It continually dings and then the cruise won’t work. We have been told the part to fix it is unavailable. It is a horrible thing that cannot be repaired.

At 9,040 miles, display reads “Service Antilock Brake System” along with warning lights for abs and traction control and a loud dinging. It goes off, then back on multiple times until serviced when the dealership replaced the faulty HCU Sept. 2020 under warranty. Diagnostic code C0020-01 ABS pump motor general electrical failure 2023 the problem comes back but nothing done. 2024 after much research, found the newer replacement HCU had just been revised in April with a new part number. At 25,837 miles back to the dealership for another replacement, this time paying out of pocket, over $300 for part and over $600 for labor. It’s only been a short time but so far, no warning about a faulty abs. I do have the old part if inspection is necessary. There is an FCA service bulletin out #S2005000004; NHTSA #10181550 It says if the HCU doesn’t fix the problem, replace...

Electronic Braking System failure. ABS lights come on the dash, chimes constantly and disengages the cruise control. The vehicle looses ability to use ABS. Ability to control vehicle safely when ABS disengages is a critical failure. I'm told by the dealer that NO parts available from the manufacture to cure this issue. This is an unacceptable answer to a known issue for years. Many RAM owners have complained about this on RAM related forums and on YouTube. I am adding my vehicle to list of vehicles impacted by this catastrophic failure to create a safe vehicle to drive. Why has the NHTSA not fined RAM and forced a recall? How many people have to die from ABS braking failure to qualify for a recall? I don't want to be the last death before something is done to make my truck safe to drive.

While driving, the "service electronic brakes " and traction control light will come on periodically, then go away. The issue is random and not consistent or easy to predict. If the cruise control is active, the cruise control will disengage and the truck will start to slow down. The brakes seem to work the same even if the light is on or off.

The known issue that Ram refuses to is plaguing my truck. ABS and Traction Control lights come on. This shuts off the cruise control as well as makes braking difficult. It is very dangerous. This is a ticking time bomb. Vehicle has under 50k miles on it. 2017 and 2018 have been known to have faulty ECU Module and HCU. Loss of brakes momentarily occurred on [XXX]. I am having the issues under investigation. NHTSA Action Number: PE22012 Components SERVICE BRAKES, HYDRAULIC Opened From: November 28, 2022–Present The reports cited below can be reviewed at NHTSA.gov using the following ID numbers: 11143741,11182778,11231734,11252781,11265590,11270151,11300182,11319987,113409 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

For over 3 months the ABS Brake warning, the anti skid control and the cruise has not worked in my truck. I have had it to two different dealers, and opened a case with Ram. Case#89336043. They told me part is not available and has not been for the past year. Just drive my truck like it is??? I dont really know what options i have at this point. Please help!

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.

ABS module problems. Flashes to check service ABS and traction control. Then goes away and comes back. Been having issue for over a year with no results in fixing

VEHICLE: 2018 RAM 3500 Dually ISSUE: ABS Module failure RESULTS: Loss of traction control, cruise control, and brakes locking up while pulling heavy loads. A constant chiming from check engine light. INSPECTED: By several independent garages can not find replacement module. Willing to let be inspected if need be. CONCERNS: Brakes lock up and loose control,Cause a accident by rear-ending someone, can't use all the functionality of the truck such as cruise control. Iritating chiming sound make long trips unbearable.

In May of 2023 while towing my boat I got warning bells and flashing lights, alerting me of the failure of the ABS brake system. In a few miles the warning went away. Then came back on, about 12 times in 20 miles. I also lost my cruise control and traction control. I took to the dealer, about 10 times before they were able to have the episode happen. It was intermittent at first but VERY annoying and Unsafe. The ABS system is almost always in failure mode and has been since about August. They order the parts in June, I'm still waiting. I use the truck to tow a car , a 34 foot 5th wheel and numerous other heavy loads. ABS is very important as is the cruise on my long trips. I'm still waiting, no help at all from Chrysler corporation!! Almost everyone I've talked to with...

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

My ABS and Traction control lights will come on and off, making my cruise control stop working without warning. sometimes it stays on and sometimes it goes off. it is completely random. I'm seeing lots of reviews saying this is happening to others and its the HCU module and the abs control. please help get this fixed

ABS and traction control lights intermittent flashing. Service ABS warning flashes and chiming occur. Very distracting and makes me unsure of failure of system .Codes and stored messages clear and repeat. Cannot go to dealer every day to have codes read that don’t exist. Parts not available at dealer. How is this fixed?

ABS mogel is defective and needs to be replaced. ABS light and chimes come on constantly. Affecting braking and lose of cruise control ability. This is a know fact that it is a defective part on ram trucks.

The ABS light and Traction control light keeps coming on and off very frequently. I am being told it is the Hydraulic control unit, as well as the abs module. This seems to be a huge safety issue that many people are running into.

Vehicle began flashing abs light and traction control light. Took vehicle in for repair. Was told this is a known issue and they are unable to aquire parts until june 2024 currently January 2024. Drove on 1-25-24 light was off used the breaks and abs light came on and breaks locked up and continued to skid on the ice almost causing me to go threw a stop sign into a ditch.

The antilock brake system warning light because it's faulty The brake system affects the speed control And they don't have reliable parts to repair

In September 2023 I started getting a warning to service the ABS system. The warning and associated annoying tone would appear and than disappear at different times. I spoke with the service manager from Lithia Dodge where I purchased the truck. He told me that he was unable to service my truck because the ABS parts are not available. I was told that like a great number of Ram truck owners, I had to "hurry up and wait for a solution." This is unacceptable. To make matters worse, I am moving out of the country in February. I had a buyer for my truck and now it is un-sellable due to this ABS issue. I hope that a re-call will be issued soon so those of us with this common issue can get some relief. Thank you

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.

Traction control and abs lights have been coming on randomly while driving over the past several years. Seems worse and more frequent in cold temperatures. Scanner reads code C0020. Cruise control suddenly shuts off when this happens causing a safety hazard especially to those traveling behind. Dash lights and constant chimes are very distracting while driving. No abs makes winter driving more dangerous as well. Seems to be a common problem with this vehicle. There should be a recall issued to fix this.
