2018 Ram 3500 complaints

The vehicle is displaying a "Service Electric Brake System" message indicating failure of the HCU and ABS system and possibly affecting stability control. There is a lengthy history of this issue with the 2500 and 3500 trucks but no fix, resolution or recall appears to be available for this issue.

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.

I have been receiving an error for my electronic braking systems and ABS since July of 2023. I have been to various dealerships to have it fixed and have been told it is on a "galactic back order" - words from Dodge to the service advisors. I have attempted several times to contact Customer Care at Dodge over many months. My cases have been closed without resolution and with false promises of management will reach out to assist me. All I need is the 2 parts to be replaced so that I can use my cruise control and not have the constant dinging of the warning for the ABS and EBS. It has been very annoying and if there is such a large back order with others having this same issue, how come there is not a recall? It is the braking system.

My anit lock brake warning keeps going on and off

The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the Electronic Braking System warning light illuminated. The vehicle was taken to an independent mechanic who diagnosed that the ABS module needed to be replaced. The vehicle was taken to a local dealer and the contact was informed that the parts were on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure; however, no assistance was provided because the vehicle was no longer under warranty. The contact requested to buy the parts to repair the vehicle; however, the manufacturer refused to sell the contact the parts. The failed mileage was approximately 160,000.

ABS and traction light on dash. At 72,000 miles, I'm unable to drive my truck due to ABS module back ordered. Either I drive it and take a risk, or let it sit and rot. Purchased brand new in 2019. I have paid 965.00 monthly since 2019 and still owe 12,000 for a vehicle I do not feel safe in. I can't send a invoice, because the mechanic is not able to fix due to lack of parts.

Abs module keeps on going out in many rams from 2500 to 3500. Making a alert sound about every 3 seconds making distractive driving I am currently #28 in line for the part in a small town and it's been 2 months now. They need a recall on this. They are being negligent by not saying there is a problem.

Anti lock brake warning lights randomly come on and sometimes continuously Dealership says module needs replacing along with numerous other customers 31 K miles

1. "Service ABS soon" and Service Electronic System soon warning light and alarm occurs at random times. Failure code C0020-01. 2. Unsure if the braking system will actually work when needed. This vehicle is used to tow large heavy trailers and I just don't trust the breaks. 3. Took it to a repair shop since my warranty has expired. 4. No warning prior to failure. Failure occurred Jan 2024.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the "ABS System Fault” message was displayed. The vehicle was taken to the dealer, who diagnosed failures with the ABS control module and ABS pump. The vehicle was repaired, but the failure reoccurred 7-months later. The vehicle was taken back to the dealer and was diagnosed with ABS control module and ABS pump failures. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer and it was determined that the ABS control module and ABS pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 9,000.

Bought from a dealership a couple months ago (JAN 2024). Immediately started blinking electronic ABS error. Took in to get serviced, and now maintenance department is stating a replacement HCU and additional service will cost around $3.5k on a vehicle that has around 68k miles.

ABS AND TRACTION CONTROL LIGHTS ON DUE TO FAILURE OF ABS MODULE AND PUMP. NO ACCIDENT BUT FEEL THERE COULD BE A PROBLEM IN THE FUTURE CONSIDERING THIS IS A SAFETY ISSUE

Loss of ABS braking and traction control

Service and systems and service electronics brake system warnings at approx 50000 miles. Dealer is saying it is an HCU failure

The Anti-lock Braking System module and the Hydraulic Control Unit originally equipped on 2018 Dodge Ram 3500. Vehicle is available for inspection upon request. Problem has been identified in 2020 by dealership upon delivery when issue first presented itself, and fixed by dealership. Issue came back in January 2023. I took the vehicle to an independent mechanic and the module was sent to have fixed. When the part was sent back after repair, the problem wasn't fixed. There were no known issues prior to the failure.

The ABS warning light illuminates, and warning chimes continually go off as I drive. I've been literally waiting years for a fix (since 2020). The dealer says the parts are unavailable. In the meantime, I intermittently have no ABS, cruise control, or trailer brakes. This is concerning because I tow a heavy trailer. It is very easy to lose control if you're not careful.

The ABS systems constantly shuts down, causing the Traction Control system to shut down. When I recently went on a trip towing my trailer I needed to stop on a downhill wet incline. When I first applied the brakes the system was working properly but failed during my stop and it caused a significant steering issue as I had to now react differently. This is a safety concern and RAM knows about it. I am paying for a vehicle that is unsafe to drive in less than perfect conditions. Very dissatisfied with RAM

ABS failure light started coming on along with service electronic brake system. Dealer shows I believe code 0020 which is the ABS/HUC pump failure. Dealer says seeing it quite often, hard to get parts as each part is allocated and tested before leaving. So I either stop driving it and wait for parts which seems to be a known issue or keep driving and hope for the best while the engineers try to figure out what is going on. Currently it is sitting at the dealer as they try to get the part before we leave on a trip at the end of the month.

ABS light started flashing and cruse control quit working. Scanned for codes and found P0020-01 ABS control module. Searched online and found 1000's of cases of problems related to this.

ABS,brake system came on first time on or about july 8th or so,in bad weather, hard rain had to come to sudden stop and lost control wheels locked up. But no harm done just nerves Dealer said bad control unit antilock brake system and replaced hydraulic brake part at 18386 miles, all good since. now its back same thing now there is 32210 miles on truck and same thing now ,abs brake system. Trackion control They said internal failure of unit the first time . Now we have to start all over again with the risk of braking safety at 32210 miles on Ram

The following messages appear randomly and frequently resulting in a dash lamp/ chime and loss of cruise control electronic braking system fault. HCU electronic error (stored code) many reports of the same problem I've read about.

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.

I WAS PULLING MY 5TH WHEEL TRAILER DOWN THE INTERSTATE, AND MY ENGINE FAN CAME ON "HI". THE SUCTION FROM THE FAN CAUSED THE RUBBER FAN SHROUD TO BECOME SUCKED INTO MY FAN AND IT CUT IT INTO LARGE PIECES. THOSE PIECES WERE THEN VIOLENTLY THROWN INTO THE RADIATOR AND PUNCTURED IT RESULTING IN LOSS OF ALL ENGINE COOLANT. THIS IS A KNOWN AND DOCUMENTED MANUFACTURER DEFECT RANGING FROM 2014 TO 2018.

02/11/2021 - ABS module unit replaced under warranty 06/2023 - Intermittent dash warning lights and chiming alert occurring. Dodge dealership states it needs a new ABS module, however the part is "backordered" and not available. Truck is out of warranty. 09/2023 - Dodge dealership informed me that part cannot be ordered until January 2024 01/2024 - Dodge dealership states that part is still backordered and none are available. 05/02/2024 - Part is still unavailable. Warning lights and chiming has been occurring for a year and there is no other way to fix the problem. Why are so many of these vehicles experiencing the same problems with owners unable to replace the faulty part?

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 the ECU, but that is not available and no ETA. Lucky to get the HCU because that is a very limited part. This is a safety issue because not only does the ABS and traction control go out but you also lose cruise control and 4wd while driving. There should be a recall with all the complaints. Not sure what good a recall would do if parts aren’t available anyway. Telling someone who just spent a fortune on buying this truck not to drive it because of this, is not an option.

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.

The truck is getting constant ABS failure messages, such as (1) “Service electronic braking system”, and (2) “Service antilock brake system “. When either of these rear their ugly heads, there is multiple loud dinging sounds (which startles the driver), and the cruise control gets turned off. Why hasn’t there been a safety recall?!?! If you guys can’t see that a failed braking system is NOT a safety issue, then our country is way worse than I already thought it was!!!! BRAKES ARE A SAFETY ISSUE!!!! Not only are they a safety issue, but thousands and thousands of 2017 & 2018 RAM 2500 and RAM 3500 owners are having these exact issues in the United States!! WHY ISN’T THERE A RECALL ON THIS ISSUE?!?! Are you just going to wait, until you have multiple DEATHS, before you do something to PROTECT owners?!?!

ABS FAILURE / DEALER SAYS WAITING ON PARTS/ WAITING FOR OVER ONE YEAR

ABS FAILURE / DEALER WAITING ON PART FOR OVER ONE YEAR

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)

I get a message on my dash to service antilock brake system. The lights come on as well as the check engine light and there is a bell that dings when this happens.

ABS brake module fails and the vehicle looses its ABS braking capability. Other functions are affected as well, anti skid and cruise control. Major safety issue! This vehicle is now in need of 3rd module in under 100,000 miles. This is unacceptable Stellantis/Chysler Corporation has full knowledge of this component weakness and has not improved or recalled this part. Thank you

Abs and traction control continues to fail. I bought all new sensors. Then replaced abs module and pump and lights went away, after a year they all came back on and it's a repeat process.

The alarm light and bell goes off. The 'Service Antilock Brake System' and 'Service Electronic Braking System' lights flash. This occurs intermittently while pulling a 5th wheel camper. The brakes work @ 30-40% strength. This is a safety issue. We thought it was an issue with the campers breaks, however, after connecting it to another trailer, the same thing happened. We had to take it to the dealership with a trailer to get it to repeat issue so that they could determine what the issue was. The Dealership ran a Diagnosis on the truck and the DTC, Diagnosis Trouble Code was C0020-01 ABS Pump General Failure. The dealership recommended replacing the HCU, Hydraulic Control Unit. They did not have the part and said it was on backorder. The unit costs $830.49. This doesn't include labor.

Abs warning light indicator is on. Dealership says abs module and pump have to be replaced, but parts are not available. I've been waiting since Nov of 2023.

Originally had a warning light show on the dash that said electronic brake system failure and an ABS warning light. Spent over $800 to have this problem repaired and in less than a year the part failed again and same problem occurred. However, his time due to price increases the repair will cost over $1200. When this happens you lose your ABS brakes as well as the ability to operate the cruise control. This is a known safety issue with thousands of trucks affected and Ram refuses to address the problem other than to charge the consumer to replace a part which will knowingly fail again. Even worse, according to my dealer the part isn’t currently available and their recommendation is to not drive the truck until the problem is fixed because the ABS brake failure is a huge risk/liability. I would really appreciate you looking into this matter and please contact me with any help/info that you may have.

1. Repeated alarms for "Service electronic braking system" & "Service antilock brake system". 2. Loses crus-control during alarm. 3. Loses Posi-track system during alarm.

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 lite comes on no parts available 60,000 truck not safe to drive mine not only one ingoing trouble with a lot of

ABS/TRACTION CONTROL light comes on and goes off at random times while driving. Sometimes when I hit a bump, other times just going down a smooth street or even sitting at a stop light or just sitting at idle in a parking lot. When the lights are on I do not have use of cruise control, traction Control or ABS. I had the code read. It shows c2200-49 ABS internal electronic failure C0020-01 ABS pump motor control - general electrical failure. This has been a problem for about 2 years, and started around 85k miles. Sometimes it happens 30-40x in a 30min drive, other times I'll go weeks with the system working properly, then It starts acting up again. I just recently heard they were investigating the 2018 models for this issue.

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

The ABS HCU failed and sent a "service electronic brake" warning to the dash. The replacement part was in short supply by Stellantis because there are so many vehicles with this problem. The dealer is limited to one part replacement per week.

The rear lug nuts sheared off two different times hauling a camper, also was involved in a wreck where the truck hydro planed now the traction control lights are on also the low coolent light is on and there is plenty of fluid in the tanks

Failure of the anti-lock braking system/hydraulic control unit. This is the 2nd failure. First failure was repaired November 22, 2022 for $1127.37.

My electronic braking system and abs is malfunctioning with a light on in the dash, it started out intermittently and is now constant. Took it to local dealer and they ordered parts to repair it but told me they were on back order and then Chrysler canceled the order on them unbeknownst to me or the dealer. Contacted Chrysler and they have no idea when parts will be available. I can get no guarantee on weather or not my truck is safe to drive as is.

ABS, Cruise Control and Traction control warning lights constantly flash on dash informing me that they are disabled. Dealer is saying that Ram canceled their part order for the ABS module part number 68347098AC needed to do the repair with an estimated 1 year date before it is available. Truck is unsafe to drive due to ABS and traction control being inoperable and was warned I may be liable if I choose to drive it and an accident were to happen.

Abs/traction control light. Dealer says it needs a new abs module and pump. It’s too new to have these issues, dealer states that it is not a recall and I would have to pay out of pocket ($1600) for the repairs. This is not safe at all. I live in indiana and doesn’t like stopping when the road is snow covered. Ram/chrysler needs to have this recalled immediately. This is very dangerous!!

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.
