2018 Ram 2500 complaints

The hydraulic control unit for the antilock braking system failed, causing a repeated dinging and loss of all antilock, breaking traction control, and cruise control capabilities. Dealership quotes parts are almost a year out, and I will be stuck driving the vehicle in an unsafe manner until it is repaired.

Abs / traction contol light keeps coming on. dealer not able to replace part because of so many trucks having this same problem that the new ABS hydraulic control unit (HCU) will not be available until sometime in 2024 and will be up to all customers to replace at customer cost. should be a recall done becuase there is an over 50% fail rate on these units. 2017-2018 ram 2500 trucks

The Anti Lock Brake light and traction control light is on and going on and off. I am told that the HUC is in need of replacement and none are available for a $60000.00 Truck sold by Ram. This is clearly a safety issue, (Brakes) and either a Recall or a buy back of the effected vehicles need to be done. What can you do since Ram seems to be sweeping it under the rug??

Abs light, traction control and electronic braking system. Took to dealership, said its a known problem. No parts are available until February 21 2024.

ABS light and traction control light continues to be on. Disables the 4wd drive. No traction control

1. ABS/Electric Stability Control service antilock brakes lights flicker on and off. 2. When ABS light is on you could lose control of brakes due to possibility of wheels locking up. 3. Went to the dealer twice to correct the problem and still having the same issue. 4. The vehicle was inspected and worked on by Ram Dealer. 5. No warning lights before failure.

Intermittent ABS and traction control lights. Service lights come on and go off when braking or driving over bumps. Code C0020 - ABS Pump Motor Control General Electric Failure. Issue is so random I haven’t taken the truck to a service center.

Abs problems due to HCU

I have been trying to get my vehicle with 17 k miles repaired since May 2023, and to date the parts, ABS Module and HCU pump are not available. Winter is fast approaching and my ABS light continues to flash also disabling the cruise control. The constant dinging is very annoying and driving the vehicle continues to be very aggravating. I have repeatedly contacted my local dealer and they continue to push out the date when parts will be available. They are not able to confirm engineering design review due in February 2024 when parts might be available. Really! Would it be possible for NHTSA to advise me on maybe when a solution to this problem might happen.

The contact owns a 2018 Ram 2500. The contact stated that on several occasions while driving at various speeds, the electronic brake control unit warning light illuminated. The vehicle was taken to the dealer where the ABS was replaced. The manufacturer was notified of the failure. The failure mileage was 21,000.

Tractions control and abs light consistently flashing. Throwing a code for the HCU. I see there’s a class action lawsuit for this already placed.

I keep getting warning lights for ABS problems. Saw there was recalls for the 2019-2022 and saw there was a class action law suit for the 2018 models.

Abs light is on. Needs an abs pump. The pumps are not available from Chrysler. This has been an issue on my truck since November 2022.

The truck started intermittently throwing code for C0020-01 (service Antilock Brake system). I will intermittently lose ABS/Cruise/trailer brakes, and being the primary vehicle in our family, the truck has become unsafe to transport my wife and 7 months old child. I've aware the HCU/ABS module both need replaced, but some of these parts aren't available from the dealer, and it will be multiple thousand dollars to repair IF they ever get the parts in. This is a known, very dangerous, safety issue that FCA need to address.

Continued failure of hydraulic control unit (HCU) and Anti-lock brake system (ABS) module causing fluctuations in brakes at times (have to press harder on brakes) and lights go on and off, sometimes staying on for lengthy periods (usually on highway) or while driving and disables the cruise control. Second time in just under 3 years (fixed in Nov 2020 and reported to dealer Sept 2023), same issue on parts both time, fix identified as faulty HCU and ABS module as dealer identified issue and placed order for parts (5 month backorder to Feb 2024 as apparently very common issue with these trucks). The issue is both the change in brake sensitivity due to this part failure and the sudden cancellation of cruise control, the braking impacts the braking performance and cruise control drop out causing sudden drop in speed on highways.

While driving the ABS warning light, and traction control light illuminated, along with a chime. The messages "Service Anti-Lock Braking System", and "Service Electronic Braking System" showed on the dashboard screen. These warnings would come and go very frequently while driving, each time with an audible chime. At times, this would happen every 4-5 seconds, making it very difficult to concentrate on the road. Sometimes the messages would be gone for 1-2 hours but would always return. When the warnings were present, the truck would have no ABS, traction control, or cruise control available. This made towing a trailer much more dangerous. My truck was out of warranty but only had around 33,000 miles at the time. The local Ram dealer replaced the ABS module, as well as the brake hydraulic control unit. The problem has not returned. I have since learned from the online community that this is a very common problem and think it's something the NHTSA should look at. Due to the frequency of which these failures are occurring, a lot of owners aren't able to get their vehicle fixed because of the increased demand on the parts required.

My dashboard keeps flashing “Service Antilock Brake System” and “Service Electronic Braking System”. The warning or notification goes out and comes back almost every time you hit a slight bump in the road or even if you don't. Seems to be very intermittent. Cruise control goes out when the lights are on and the truck lurches a bit. The dings and lights flashing are very annoying. Took it in to my local dealer and they checked the electronic codes and found a new module is $510 and NO ETA to dealer and the HCU is $262 and not available until 2/21/24!!! Total to install will be $800+ NOT covered under any warranty. They tell me it's not dangerous to drive since I can still brake....REALLY??? No ABS brakes seems to ba a severe problem to me. There is a class action lawsuit about this in CA: The FCA Ram defect class action lawsuit is Neu, et al. v. FCA US LLC, et al., Case No. 5:23-cv-00509, in the U.S. District Court for the Central District of California.

ABS service warning and Traction control light shows intrmittently and disapears Planning to take to dealer

Abs light continusly going on and off

The truck has a faulty antilock brake hydraulic assembly. The ABS and Traction control warning lights illuminate intermittently, especially when hitting bumps in the road. When the lights are in the ABS brakes and traction control systems are not available. The trouble code in the ABS module is for an open circuit in the ABS pump motor. When the issue occurs and the lights are on the ABS brakes and traction control do not function correctly. I am a professional automotive diagnostician that owns a vehicle diagnostic business and I am also a college instructor for automotive courses. So please understand this issue was diagnosed properly. I have diagnosed the issue to an open circuit internally to the ABS pump motor which is part of the ABS hydraulic assembly. The motor was disassembled and Inspected after all of the external circuits were properly diagnosed and no issues were found with any associated external wiring or controls. It was found that the brushes in the motor assembly that contact the commutator inside the motor are sticking in the brush holders. This sticking of the brushes in the brush holder cause the brushes to lose contact with the motor rotor which then causes the code to set and the lights to illuminate. This is more apt to happen when the motor is shaken by the movement of the vehicle hitting bumps causing the commutator to move away from the brushes which are sticking in the brush holders. This in turn sets the motor circuit open code. I have diagnosed t

The ABS system has went out again. This is the second time owning this truck and back orders are 9 months out. First time wears around 30k miles. It’s a common problem with this year truck. From new to old.

Abs/traction control errors Alarm keeps coming in and going off This is the 3rd time this truck has had the same issue

2018 RAM 2500, 140,000 miles. During a long trip home to ND traveling on interstate 29 in SD warning lights appeared on the dash indication ABS problems. The cruise control also stopped working. We checked it with a code reader and it indicated a cose associated with the ABS brake system failure. ABS brake system failure, ABS pump motor control failure, also affecting loss of cruise control. Code C0020-01 confirmed. RAM dealers report that corrected replacement parts are not available and loss of brakes could result possibly causing harm to the vehicle and passengers.

Warning light stating "Service Automatic Braking System". Failed ABS module and Hydraulic Control Unit resulting in absence of Automatic Braking System brakes. Taken to Dealership and told unable to fix due to inability to find parts...Earliest part will be available is 6 months from time of inspection.

Anti-lock braking system has failed for the second time. First time was 2 yrs ago while under warranty. Truck only has 47430 mi on it.

The ABS pump has failed for the second time, my vehicle has less than 80000 miles on it. The first replacement was covered under factory warranty. I have researched this issue and have found this to be a common issue and at this time the factory is not issuing a recall. Dodge/Ram is well aware of this issue and the repair should be covered as a factory defect.

ABS, TRACTION CONTROL LIGHTS ON, DEFECTIVE HYDRAULIC CONTROL UNIT. SECOND TIME IT HAS GONE BAD, WARRENTY THE FIRST TIME, NEEDS TO BE REPLACED AGAIN, NEED TO LOOK INTO A SAFETY RECALL.

Warning ding followed by dash informing me that traction control and electronic braking has problem. Local dealer has confirmed problem in Feb. 2023. Dealer states replacement part not yet available and no estimate as to when part will be available.

ABS Failure Code 0020.1/1

2018 RAM 2500 diesel purchased brand new in October of 2018. Continuous issues with the ABS Module and hydraulic control unit starting at approximately 23,000 miles. This was unfortunately past the 3 year bumper to bumper warranty. This affects the performance of the ABS brakes, including the brakes freezing up in the closed position, along with a constant chime and notification on the dashboard. Upon doing research this appears to be an extremely common issue with the 2018 models and a recall has already been issued for the 2019 model. The OEM ABS modules have a 6-9 month wait when ordered and the repair is approximately $1,500.

Whenever it rains or is high humidity, my dashboard lights up and repeatedly chimes with ABS lights and Electronic Braking System error. The error repeats itself on and off again every few seconds. It is a dangerous distraction of error messages. Since it is raining, all traction control and ABS systems deactivate themselves with this error. I spun out this morning due to the error. It is absolutely dangerous. This is the EXACT error that occurred on my previous Ram. This is a dangerous faulty hydraulic control unit (and ABS system). Upon a little research, I found tens of thousands of posts of owners being stranded or driving without ABS / traction control due to this malfunction. This is deadly and needs to be recalled. RAM is aware of this issue but has not issued a recall. It is raining today, and my RAM will not have traction control or ABS. This is unacceptable. This is affecting tens of thousands of owners. With upwards of $1,600 for a repair. Yet, the part can create a fault AGAIN within weeks or months. DANGEROUS.

Braking failed on vehicle, manufacturer refuses to provide repairs parts nationwide on all Ram 1500,2500,3500 trucks

My 2018 RAM ABS warning indicator light goes on and off continually. Also the HTC control unit warning lights. Dealership has a back order of 12 months is not more to replace the parts. 123 ordered at our local dealership alone. Please force Dodge to recall and replace faulty parts at their expense.

ABS light and traction control light are coming on. Causing excessive dinging and cruise control not working. Also experienced flat spotting on my tires.

38k miles ABS Unit has been replaced along w hydraulic pump. Just over 2 yrs 20k miles it’s out again! This is a know problem and they will not take responsibility for it! What has to happen someone die because of the ABs failure?

The ABS and traction control warning lights recently came on causing the antilock brake system to not function. Took the truck to the dealer and was informed that the HCU for the antilock brake system is bad. I was told that the replacement part is on back order and they have not been able to locate one yet.

Service ABS lights on the dash, bad pump, brakes locked up in two different occasions. Truck is at the dealership, however, I need to pick it up due to no parts available to repair. My extended warranty is about to expire in the next 4k miles and I should not have to pay for this repair out of pocket, when I took the truck to the dealership before the warranty expires for this issue. My research revealed that this is a known problem with these trucks, which is totally unacceptable for the price we pay to purchase them. This issue started at around 34,000 miles. ***Last Dodge I will purchase****

Hydralic control unit is bad causing on dash safety alert for service electronic brake system alert and anti lock brake system alert. When towing will not have brakes to assist in stopping tow vehicle. The alarm constantly going off distract your attention from the road. Upon going to the dealer for repairs I was told they are on national back order and may not be available until after the 1st of the year. It apparently a widespread issue with all 2017 and 2018 Ram 2500s. I am unable to tow my 38' 5th wheel camper for fear I will lose my brakes on the tow vehicle putting myself and others at risk. The anti lock brakes not functioning properly could result in losing control of the vehicle when road conditions are wet or slippery. This loss of traction put me and other motorist at risk. Ram know there is a problem with the HCU. My understanding is they have had to completely re-engineer the part and as such has created an availability problem for anyone owning these vehicles. There are several blogs and forums online describing this as well as a class action suit initiated by the state of California. Would appreciate you looking into this matter and getting Ram to do the right thing. Thank You

Abs and traction control issues. Intermittent lights come on and lose cruise control. 2018 Ram 2500, with 29000 miles.

The contact owns a 2018 Ram 2500. The contact stated that the "Service ABS" warning light would intermittently appear on the instrument panel. The contact used a code reader which retrieved an ABS pump motor control failure. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 50,000.

I am experiencing intermittent warning by dash red light, warning dings & digital warning. Check brake system. The issue seems to be increasing in frequency as the last time I used the vehicle-it dinged every few miles. I understand that the ABS & TSC systems are inactive when warning displays. I called my local dealer to have vehicle inspected/ repaired and was told to come in for diagnosis but the parts for suspected failure are not currently available. I am in an area with rain expected for several days and am concerned with driving under these conditions.

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.

Anti-Lock Braking System Faulting. Near catastrophic incidents while towing.

The ABS/Anti Skid warning lights and notifier goes off every one to three minutes, clears itself then repeats. I travel two hours to work and return to the obsessive malfunction.

The ABS and traction control indicator lights come on and off intermittently. This is a huge safety concern has the ABS and traction control may malfunction. This issue has been brought to the dealer and they replaced parts less than two years ago. It has reoccurred less than two years later.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the ABS and traction control warning lights illuminated intermittently, and a message was displayed stating that the cruise control was unavailable. After restarting the vehicle, the vehicle returned to normal functionality however, the failure became a regular occurrence. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 22V140000 (Service Brakes, Hydraulic, Electronic Stability Control) but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 56,000.

I purchased 4 new tires and wanted a front end alignment. There was an issue with drag link so the fox was Chrysler to weld draglink now that has been done before I purchased truck I can’t do alignment. Dealership said should be covered but have to wait until they hear from Chrysler. Going in 5 weeks still haven’t heard back I have called numerous times!

IN 2020 MY ABS CLONTROL MODULE FAILED AT ABOUT 20000 MILES. I HAD IT REPLACED UNDER WARRANTY WITH NO ISSUES. IN MAY OF THIS YEAR (2023) IT STARTED FLASHING ON AND OFF WHILE DRIVING AGAIN. I TOOK IT TO THE DEALERSHIP AND THEY TOLD ME IT NEEDED REPLACING AGAIN BUT THEY DO NOT HAVE AND CANNOT GET THE PART. IT HAS GOTTEN WORSE AND WORSE. I CAN TELL IT IS AFFECTING MY BRAKES ALONG WITH I CANNOT USE MY CRUISE CONTROL. I HAVE BEEN BACK MULTIPLE TIMES TO CHECK WITH THE DEALERSHIP AND THEY TELL ME THE PART IS BACK ORDERED. LAST TIME I WAS THERE IN SEPTEMBER THEY TOLD ME IT WOULD BE FEBRUARY OF NEXT YEAR AND THAT IT IS NOT COVERED UNDER POWER TRAIN WARRANTY SO I WILL HAVE TO PAY OUT OF POCKET FOR SOMETHING THEY HAVE ALREADY REPLACED ONCE FOR SAME ISSUE.. THE BRAKE LIGHT, TRACTION CONTROL LAMP, AND ABS LAMP ALL FLASH ON AND OFF CONSTANTLY WHILE DRIVING

ABS system needs maintenance, no fix up to this.point dealer does not want to assist.

Abs traction control light has been going on and off since truck has had 15000 miles dealer replaced abs pump still has issues light is intermittent when it comes on cruise control shuts off truck now has 53921 miles on it and the dealership doesn’t know why light goes on and off
