2018 Ram 2500 complaints

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated, and the Adaptive Cruise Control mode became inoperable. The contact stated that the failure had been recurring while driving, and a chime sounded each time the failure occurred. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the hydraulic control unit (HCU) and the ABS module needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer, where it was diagnosed that the hydraulic control unit (HCU) needed to be replaced; however, the part was on a national backorder. The vehicle was not repaired. The manufacturer was notified for the failure. The failure mileage was approximately 30,000.

Service ABS and Electrical Braking System lights constantly turn on and off making an audible beeping noise while vehicle is driving. Sometimes lights stay off for a little, other times it turns on and off repeatedly, and sometimes it stays on for entire time. Unknown if braking system is working properly if they were needed in an emergency situation.

2018 Ram Sept 23, 2020 at 15,000 miles ABS light flashed on. Code said pump electrical failure. Dealer replace under warranty. Oct 12, 2023 at 50,900 miles, service ABS notice flashes on screen. Dealer confirmed ABS failure but said parts were on indefinite back order. Said last one took over a year to get parts in.

Intermittent warnings of ABS system needing maintenance while driving. No known cause or correlation to type of road/weather conditions. Intermittent ABS failure affects ability to use cruise control. This started when the truck was at 52k miles. This has been happening for over a year now and we have been told that there is an indefinite timeframe for repair due to massive back orders.

Bought the truck new in 2018 from Planet Dodgein Miami. One year later (2019)the service braking system light came on. Dealer fixed the issue under the warranty. One and a half years later (2021, same issue and the dealer fixed the issue under the warranty at Napleton Dodge in Clermont Florida. 1.5 years later (2022), same issue. Dealer (Advantage Dodge Mount Dora Florida. said they needed to replace the same parts and added they needed to replace an additional part to correct the issue. This time I was charged $1000. Another year later (10/2023) the same issue and I'm being told by Advantage Dodge in Mount Dora Florida, the warranty will not cover and I have to pay $1500. Dealer told me it should be covered under the original warranty. Gave me the number to warranty (800)992-1997 (Trevor) told me not covered any longer and the dealer should warranty. Called the dealer back and they told me to call the number back. I did and was told a second time and they told me it is no longer under warranty and they (Eta) told me to call a second number (800)521-9922. Called that number and they have me a third number to call (800)765-7732. They told me the dealer should handle the issue and it's not covered under original warranty. Now the dealer will not return my call and they still have my truck.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated. The contact stated that the ABS module had previously been replaced; however, the failure recurred. The vehicle was taken to the dealer, where it was diagnosed that the ABS module needed to be replaced a second time. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 33,000.

ABS warning light intermittent chime and warning. It affects cruise control and highway/street handling. Warning light and chime stays on or is intermittent.

Almost constant beeping and flashing indicators telling me to "Service Anti-Lock Brake" system. Taken to repair shop and they tell me there is not a fix and there is an engineering stop on the HCU. A code read returns an active C0020-01 code. The brakes do seem to work but the ABS and Traction Control indicators flash constantly with the beeping. I haven't test the ABS functionality but would assume it is not functional based on the indicators.

Vehicle randomly throws error codes on the dashboard. 1. Service Antilock Braking System 2. Service ABS Braking System. When this occurs, an audible chime sounds, and a visual warning warning displays on the digital dashboard covering current speed and other information. Also the cruise control is turned off, and I believe all ABS and Traction control features are disabled. While I have not yet experienced a related accident, I have had several close calls with other vehicles following behind me. By the time I react, they are on or near my tail end and nearly rear ended me. I contacted my local Dodge Ram dealership and they told me that the needed part (hydraulic control unit) has been backordered for nearly 4 years. They cannot disable the warning light nor the audible chime which may sound and flash 15-20 times a minute sometimes. They suggested I contact Mopar customer service, which I did and they ended up transferring me to another dealership that said I had to pay 300 dollars for a diagnostic and it would 2-4 days. If they cannot find the replacement part, I am out of luck on the diagnostic fee. No parts are available.

My ABS HCU sensor has failed and is causing my ABS system, traction control, and cruise control to stop working. Due to the high failure rate of this part RAM / Mopar is refusing to release any available parts for repair until February / March 2024. There are currently 4,000 of these parts in stock on the east coast but the company will not release them until 2024. Instead RAM / Mopar is asking me to continue driving my vehicle for 5 months with a failing ABS system, no traction control, and intermittent 4WD. The component has been inspected by the local RAM dealership and has been determined to be faulty while under warranty.

One month after the 3 year warranty ran out the truck issued a "Service ABS System" alert on the instrument panel. Had to replace the ABS Hydraulic Module at the dealer. 2 Years and 2 months, just after the additional warranty ran out, the same part failed again. Same warning on the instrument panel. Again took it to Ram Service at dealer and had it replaced again. This is a faulty part and the replacements are faulty as well. It is happening so often that it is hard for the dealer to find the part.

The ABS Motor circuit on my truck is losing power. The issue is this is part of the Hydraulic Control Unit assembly and it is not serviceable without replacing the HCU. Ram does not currently have a solution to this problem. This issue shuts down my Anti-Lock Braking System, traction control and I lose trailer brakes when this system fails. This is a safety issue and a recall needs to be issued for this.

In October of 2021, my truck indicated an issue with the ABS System and the EBS System. Those two alarms would frequently go off randomly while driving, and also the cruise control would not operate during this state of alarm. It was fixed immediately by a RAM dealership; they replaced the HCU module (hydraulic control unit): part #68143491AA. Almost two years later, in September of 2023, the exact same thing happened and I took it back to the very same dealer; they confirmed the same issue and it would need a replacement HCU again, however I was informed those parts were all removed from inventory as they are being redesigned (fixed) to prevent more issues in the future, as this is a "known" problem. I am awaiting a call from them when the new "fixed" part will be available (it could be months). In the meantime I am driving the vehicle knowing that the ABS braking can go out at any time, thus driving more carefully than normal. It is also worth noting that about one month after the second occurrence of this problem, while driving with a faulty HCU, my brake line on the front driver side wheel (just about one foot from the HCU module) burst while driving and I lost almost all braking in a matter of 5 minutes. That brake line was repaired at my expense. It seems to me that could be related to the HCU issue possibly causing higher than normal pressures in the line. In my opinion, this situation is dangerous and should be raised to the level of a RECALL on that HCU part. Also, R

The ABS light comes on intermittently with a message to have braking system serviced. This causes a loss of braking performance, & cruise control. With this happening intermittently, it is impossible to have repaired by dealership. As the error disappears. I had also had this issue with a 2017 RAM 2500 I owned previously.

Hydraulic Control Unit Failed. Yes, it is available for inspection. The hydraulic control module controls the wheel speed and traction control system, without these systems working properly it has caused traction control issues and caused loss of control of the vehicle. Yes, Patriot Dodge and Chrysler in Oakland Md Diagnosed the problem. No, the component has not been inspected! Yes, there were Two lights on the dash (ABS light and Traction control light), Also My Cruse Control would not set the speed. I lost control of my vehicle and fortunately there was no property damage, and no one was injured. If the ABS and Traction control system had been working properly this incident would not have happened. This is definitely a safety issue for these vehicle owner's and the motoring public as well as anyone in the immediate area.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, the ABS and Traction Control warning lights illuminated. The contact indicated that when the failure occurred the cruise control suddenly deactivated causing the vehicle to decelerate. The vehicle was taken to the local dealer who diagnosed that the ABS module and HCU were faulty and needed to be replaced. The vehicle was repaired but later the failures reoccurred. The failure mileage was 26,448.

Service Anti lock Braking System light came on. Took it to the dealer and was told I need a new Hydrolic Control Unit, but dealer can not even order one until February 2024 at the earliest. I now how an unsaved truck I am just stuck with

The service anti lock break system and the service electrical break system warnings keep flashing. The traction control light and the ABS light continuously flash as well.

ABS service light coming on, and service electronic brake system keeps coming on. Recall on 2019-2022 RAMS for same issue. Told to report issue here.

Intermittent ABS service warnings, This is a well know problem.

My 2018 Ram ABS and Traction Control light keep coming on then they go away for a few miles then come back. this item has been fixed but it came back. i spoke with the mechanic but he said, Rams have had this trouble. i'll have to keep dealing with it till they come out with a solution. i looked up the problem and seen numerous complaints same problem. i can disconnect the fuse and not have the warning bell but hen no ABS brakes. has there been a recall? (previous owner had it repaired twice but it keeps doing it.)

My Anti Lock Brakes, Traction control and power steering have gone out repeatedly on this vehicle. The ABS pump HCU unit has failed at 8,433 miles. The same thing failed again at 12,924 miles. As of this complaint the same thing has failed again at 20,000 miles. I have not had it repaired because Ram will not guarantee the new part they put in is not defective, like the original part and the 2 other replacement ABS pump they installed which have failed. I don't drive my this truck that much because without the abs for which the break system on the truck was designed for I feel like it is a danger to myself and others.

My abs brake light goes on and off cruise control just stops in the middle of the highway. I was almost hit by an eight wheeler while commuting because of it. I loose traction driving on wet roads. I have taken it to the dealership more than twice to fix the problem. So solution in sight.

Complaint already filed. Have been waiting on HCU module and ABS module for over 1 year. Intermittent braking issue, and trouble code is constantly going off. Called dealer every 3 months and no part available. They say it is an engineering hold by Ram. Latest update is to check back 2/2024.

The ABS system is not working. The warning lights for ABD and skid prevention are lit. During hard breaking the tires will lock up and slide. This also turns off the cruise control.

On or about September 2023 this vehicle, with 94k miles, has had its 2nd ABS/HBU failure. This causing the ABS and traction control lights to flash on and off with audible alarm then continuous illumination. We as a consumer buy these heavy duty vehicles to use for pulling trailers and heavy loads, It is no longer safe to do this when there is an imminent threat of brake failure. This can cause the consumer to be out financially in many ways. This component was previously inspected and replaced in 2020, with roughly 20k miles, by the dealer I purchased the truck from. Currently I have been unsuccessful locating and OEM replacement part causing the vehicle to be parked. This is a well known and documented issue on 17-18 Ram 2500-3500 heavy duty trucks that the consumer would like remedied for the safety of themselves, their families and others on the road around them.

I have had an ongoing issue with the ABS & ESP warning and warning light coming on and off. I took it into the dealership and they told me I needed to replace the ABC controller & hydraulic control unit. I don't understand why this isn't a recall or covered by RAM. I am afraid the brakes are going to fail putting my life and others in peril. I was told the repair would cost me $1200 so I have had to park the vehicle.

The ABS and traction control systems on our 2018 2500 RAM truck are failing randomly, and the warning lights are coming on. The cruise control system is also randomly failing. Therefore, as we drive the vehicle and using cruise control the vehicle will randomly turn off the system causing safety concerns. The braking system and traction safety systems are not working properly and safely. The cruise control issues have been occurring for about 2 to 3 months. Over the last 1 to 1.5 months the ABS and traction control systems have started randomly failing and turning on the warnings lights and bell. We took the vehicle in for service today at the RAM dealer and was informed that the parts are backordered and unknown when any parts would be available. The dealer confirmed the systems are not functioning properly and provided written estimates and summaries of their findings. The dealer advises to replace the HCU and retest the system. The dealer advised to replace the steering wheel wiring and cruise control switch. The vehicle mileage at the time of the dealer evaluations was 23,052 miles.

This is now my second ABS module that has failed. I gave a detailed description of the brushes getting stuck in the valve body motor. This particular situation is exactly the same as before. Intermittent on/off of the traction control ABS and stability system. I have not disassembled this particular unit because of the part being unavailable. Tapping on the motor itself will make the fault go away which leads me to believe that it's similar same failure. The tapping motion allows the brush to move forward and touch the commutator. I still have the original motor from my initial failure analysis. If it would be of any use, you're more than welcome to reach out and I will be glad to ship it to you. This is a serious safety problem because you never know if the system is working or not.

Anti Lock brake system and service electronic brake system message keeps going on & off every 30 seconds & will shut down cruise control if it is engaged. Happened in 10/11/2021 & now 10/8/ 2023.

Hydraulic Control Unit (HCU) has failed, causing repeated ABS and traction control warning lights with audible chimes. Vehicle is currently at the dealer to try and fix the issue. This first occurred during a long road trip with no prior issues or signs of a problem. The first time it occurred, I was towing a trailer and on cruise control. When the dash lights and audible chime went off, it kicked me out of cruise control, which immediately caused the vehicle to slow while in traffic at highway speeds. While researching this issue recently, it seems this is a common and well known issue with Ram trucks of similar year and model, with no recalls being issued.

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.

Multiple service ABS warning lights every time it is driven. ABS will not work sometimes, dealer replaced ABS HCU and continue to have same issues. This is very common in 2017 and 2018 Ram diesel vehicles.

ABS and stability control failure. First intermittent then continuous. Dealership said the problem is the HCU solely from my description. Known problem. They also said replacement parts not available to order until at least February 2024. I believe a recall is warranted.

The Antilock Braking System is faulty. The Service Braking System is faulty. I was trailering under load when I had to apply breaks due to a road hazard. My Antilock Braking system did not function properly and my tires locked up. My vehicle was in a slide while trailering a load. Fortunately I was able to maintain control and avoid an accident. I had previously contacted my dealer about the warning light constantly alerting me that I needed to service the Antilock Braking System and the Service Brake System. I was told by the Service Department and Steele Chrysler Jeep Dodge Ram in Gonzales, TX that they were aware of the issues with the HCU on 2017-2018 Ram 2500/3500. They stated that there were no replacement parts available and that I should continue driving my vehicle with the Warnings constantly going off on my dash. I am not happy about this situation and feel a resolution needs to be formulated by the manufacturer. I am aware now of many complaints regarding this part issue with this make and model. I rely on my vehicle for my livelihood. I cannot drive my vehicle as it was designed to be driven as per the manufacturer's design.

ABS CONTROL MODULE light stays on and dealer says the module is defected and has to be replaced at a cost of around $2600.00. No parts are available due to UAW strike. Told to drive it as is cause parts may not be available till January. I feel Ram corporation should be responsible for cost to repair vehicle only has 46000 miles. Thank you

This is the second complaint filed for the same issue. Tracking number 11441949. I understand there is an investigation open for this issue. PE 22-012. Opened 11/28/22. My truck was repaired under warranty December of 2021 It has failed again in September of 2023. after less than 2 years and 20,000 miles. The ABS/Traction control system as well as cruise control unexpectedly without warning stops working. Since I use my truck to tow heavy trailers this is not a very good scenario. The alarm and warning on the dash at times repeatedly and randomly sounds while driving. When this occurs I have no ABS function, or hill decent control. The Hydraulic Control Unit Part #68143491aa is the part that failed and was replaced under warranty. It has since been obsoleted by Ram and replaced by a different part #. Was this because they knew they had a problem? At any rate, I am left to pay to have this fixed again and worry about when it might fail the next time.

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.

Check engine lights came on flashing “service abs” and “ break system malfunction “. Took to dealer and had to have HCU ( hydraulic control unit) for ABS system replaced.. it was a dangerous situation as the trailer brakes were rendered useless, as was the cruise control. The breaks still worked but not the ABS part, so could possibly lock up and loose control during an emergency event.

I have a 2018 Ram 2500 which has been throwing an error code for the last year to service the electronic braking system. The dealer says it is the HCU and it is a known problem and that the manufacturer will not have a fix till mid 2024. Meanwhile my truck is not drivable as it is a significant safety hazard. The dealer says it is now out of warranty and I will be responsible for replacement costs when the manufacturer finds a solution. I live in Michigan and I now can’t drive my truck as it is a safety hazard and I can’t sell it cause nobody will buy it with this issue. The constant flashing of the “Service Electronic Braking System” code and constant dinging when the light comes on also makes the truck undrivable. Meanwhile I’m stuck with no truck.

My truck has the same issue as many thousands of other RAM owners. The forums are full of people with the same issue. It clearly is a faulty part/design or similar. My "check ABS/ Traction Control- Brake light" turns on and off intermediately all the time. It is an issue many have had and had fixed for between $800-1,000.00. For your reference here are some links to forums showing this issue in fact a OEM problem. Apparently there are class action law suits going on in Texas and California over this matter. [XXX] [XXX] [XXX] There are many more. RAM should have to furnish a recall and fix this issue at no cost. Parts are not available until February of 2024. This is a safety concern!! This issue will not allow the use of cruise control or remote start. Winter is coming and im not sure the ABS works as long as the light is on. RAM needs to supply parts faster than Feb 2024 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The abs module and the hydraulic pump have a issue that turns on the abs and light and turns off the cruise control and reverts to non abs braking due to faulty module and pump assembly that was changed already and now the wont cover this under any warrenty known faulty part

ABS/TRACTION CONTROL light comes on intermittently while driving and or braking, when this happens the cruise control quits working. Took to the dealership they diagnosed this to have a code C0020. The failure is the Hydraulic Control Unit. Which is on back order with no ETA. When the light comes on you have no ABS or traction control. The dealership inspected the fuses, wiring.This problem happens every time you drive it and can be duplicated.

The ABS/Traction Control module has a known by manufacturer malfunction where the system fails, and you can be left without proper abs and traction control. This system can malfunction causing something as simply as the inability to activate cruise control to the inability to have proper abs braking. I've taken the truck to an independent shop as well as the delarship and both times they say there is a backorder on the part that can take over a year to replace and the charge for a safety feature that is a known malfunction is over $500. Also to lead on with the frustration of this, they offer just to use your standard brakes without braking hard (as if one can control unknown incidents requiring harder braking) as well as using the exhaust brake system. This is a safety concern that needs to be addressed and fixed, and not told to wait over a years time to possibly get the control module.

Intermittent ABS light and Service Electronic Braking System lights coming on and off. Appears from previous reports this is a known issue that has been going on for years now with this vehicle and should be fixed. I purchased a new hydraulic and electronic module from dealer at around 35000 miles and replaced. Issue was fixed or so I thought, at around 70000 miles lights are intermittently on and off again. No known issue was contacting ram direct, dealer I bought vehicle from stated the electronic module is backordered and has already been replaced with another part number, I believe it was a faulty replacement from the get go. Hydraulic module was said to be under engineered testing again per the dealer. Extremely frustrating from the customer end, no cruise, no abs braking capabilities. No known deaths to this point linked to this specific issue to my knowledge but I wonder if Ram will move a little faster on the fix or recall once they have something fatal on their backs for this.

Brakes don't seem to stop as they should and now the lights came on and dealership says I need a new abs pump and there are none available

When driving down the road the anti-lock brake and traction control lights came on. Anti-lock brakes quit working making the vehicle unsafe to drive. C0020-01 trouble code was noted. HBU and or ABS module fault is apparent.

ABS and Traction control light come on intermittently causing cruise control to kick out and not work. Also causes an alarm to ding over and over. This is a known problem with the Ram HD for this year.

The ABS Control module has been replaced once for constantly giving the “service anti-lock braking system” message and making a dinging sound. The repair worked for a little over a year and it’s happening again.
