2018 Ram 2500 complaints

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the intelligent battery sensor (IBS) warning light illuminated. The vehicle was taken to an independent mechanic; however, the mechanic was unable to duplicate the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 9,000.

The Hydraulic Control Unit (HCU) has failed for the second time on the truck which causes the ABS, traction control, parking sensors and cruise control all to fail, along with the electrical baking system for pulling trailers. This is the second time this has failed. The first was replaced at the dealership on 07/22/2021 when the truck had 29,983 miles on it. It has failed again with 42,125 miles on it, and the dealership will not cover it as it is not listed as a warranty item.

My vehicle has 45347 miles. It started throwing "Service Electronic Braking system " and "Service Antilock Brake system" messages intermittently. While driving on highway, truck would abruptly throw these messages and turn off ABS, EBS and also cruise control. It appears to be a very common safety issue with 2018 RAM 2500. I took my vehicle to the dealer but he couldn't read the codes because they were off and didn't come on. This is a safety issue for driving a one ton pickup truck and especially if driven in wet conditions.

FAILED ANITI LOCK BRAKES MODULE..... I APPLIED THE BRAKES FOR AN EMERGENCY STOP SHORTLY AFTER THE CODE CAME UP FOR ANTI LOCK BRAKE FAILURE AND TRACTION CONTROL. HAD THE CODE LOOKED AT CAME BACK AS FAILED BRAKE MODULE. CODE WAS CLEARED AND THE PROBLEM WENT AWAY. SHORTLY AFTER I WAS INVOLVED IN ANOTHER INCIDENT WHERE THE ANTI LOCK BRAKES DID NOT WORK AND AGAIN THE ANTI LOCK BRAKE MODULE FAILURE CODE IS ON THE TRUCK. THROUGH INCIDENT THE BRAKES LOCKED UP ALL 4 WHEELS RESULTING IN LOSS OF CONTROL.

My 2018 ram 2500 started having the service the electronic brake system or service antilock braking system, it also showed traction warning light on instrument cluster message come at about 45,000miles it came on every time I’d hit a bump in the road sometimes it would stay on for days on end and not go out other times it would come on every few seconds and back off as quick as it came on, I got a hold of the dealer I bought truck from and scheduled an appointment, at 50,281 miles my truck was diagnosed at a charge of 112.58 and was told that “ abs pump motor needs replacing and replacement part not available at this time”, I asked if this is a new issue and if they seen it before to be told” there was also a lot of other rams coming in with this same issue” . After this discussion my eta for the part was December 18 of 2022 heard nothing so reached out to the dealer on December 23 of 2022 only to be told that it would be in January 18th of 2023,on January 18th called the dealership only to be told it will now be in on March 18th of 2023,this issue is not getting resolved and every time this warning comes on it shuts off the cruise control,traction control and the ABS which in my opinion is something I could really use in the Wisconsin winters,I’m really hopeful that you will remedy this situation this is a serious safety issue and in my opinion an accident waiting to happen if it hasn’t already

Abs control module failed at 4,000 miles on 2018 ram 2500 causing traction control and anti lock brakes to be disabled and warning lights to turn on.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds, the ABS, traction control, and brake warning lights illuminated. There was an abnormal dinging noise heard. The contact removed the fuse. The vehicle was taken to the local dealer where it was diagnosed that the ABS control module and electronic module needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was not notified of the failure. The approximate failure mileage was 36,000.

Total brake failure. Went to park at the bank (luckily was only moving at 4MPH) Went to stop and the brake pedal sank all the way to the floor. I quickly pumped them and was able to stop only inches from going through a fence. Was able to pump the peddle till it was solid again. Has not happened again since then.

The ABS/Electronic Braking system failed before the truck even hit 50K miles, but I haven't been able to get a replacement module and have been told that these items are on back-order until an indeterminate time. However, the Electronic Braking System and ABS warning lights go off on my truck daily, especially if I drive over any rough roads or bumps. I've been having trouble getting my truck inspected because these parts can't get replaced. I've also noticed that the cruise control system on the RAM 2500 doesn't work sometimes and sometimes it comes on but it doesn't want to switch off when you hit the brakes, so I had to stop using it for fear it wouldn't turn off at all at some point.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the electronic braking system intermittently illuminated. The vehicle was taken to the dealer where it was diagnosed that the hydraulic control unit, the anti-lock brake, and ABS module needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 29,000.

Ram has had many issues reported on this item. It has been a known issues yet Ram has not taken proper action to resolve this problem. Intermitted warning lights on dash, service electronic brake system.

ABS Hydraulic Control Unit failure, warning on dash, notifying loss of ABS braking, as flashing notice which turns off cruise control and removes speed register from dash while ringing interior alarm consistently. This safety issue reduces safe braking on wet/icy conditions, and has occurred on the 2018 Ram 2500 Tradesman vehicles with mileage between 15,000 to 55,000 miles.

ABS Code C0020-01

ABS / HCU System Failed. My safety was directly impacted. I was driving 70MPH on the expressway and had a SUDDEN deceleration, which nearly caused a rear-impact collision. Various warnings and lights on the dash lit up with "Service Electronic Braking System". When the ABS / HCU system has an issue, it deactivates the cruise control, ABS System, traction control, and parking detection system. The dealer is able to verify the issue. I have taken the truck to the dealer, who is reporting a part shortage and multi-month backorder for the part. This is a huge safety issue, and could have killed me and my children. This should become an immediate recall since it directly impacts the safety features of the vehicle as well as the cruise control system, which may suddenly deactivate and cause sudden deceleration. Various warning lamps display. BRAKE, ABS, Traction CONTROL.

The contact owns a 2018 Ram 2500. The contact stated that the vehicle had failed to start up after multiple attempts. The contact also discovered that the gear shifter would move while the engine was turned off and without depressing the brake pedal. The contact discovered that the brake transmission shift interlock was defective. The vehicle was initially towed to an independent mechanic who informed the contact that he did not have the capability to repair the vehicle. The vehicle was then towed to a dealer where the part was replaced. The manufacturer was notified of the failure. The vehicle was repaired. The failure mileage was approximately 80,000.

“SERVICE ANTILOCK BRAKE SYSTEM” and “SERVICE ELECTRONIC BRAKING SYSTEM” lights come on and off repeatedly.

The notification on the dash reads “Service Electronic Brake System” The truck makes a constant dinging sound while the truck is in motion. My mechanic ordered the brake control module back in October 2022 and the part is still on backorder.

Having problems with my ABS Module antilock brakes system,took my truck to Dealership , and there respond was this part was in back order and no recall, its being 5 months .my issue is for the Safety of my Family and myself on the Road,I dont want to have and accident and get somebody Hurt or worse,and my family Im very concern of Driving this truck every day. need MFG to correct this PROBLEM.

The ABS/HCU control unit failed at 16000 miles and was replaced. At 30000 miles, the same part has failed again. The parts for repair are not available at this time. Hopefully an upgraded part is being designed to fix this failure. I am afraid to drive this vehicle in wet conditions or while towing as a faulty Anti Lock Braking system (ABS) could cause a loss of control. The dealer has diagnosed the failed unit in both instances and has the parts for repair ordered. The truck has the service ABS/Traction Control alert pop up on the dash readout.

Vehicle was repaired once under warranty for the ABS and Traction Control Light coming on and off consistently. Approximately 25000 miles later the truck started doing this same thing again. ABS and Traction Control Light will consistently come on and off over and over. Will happen when I brake, accelerate or let off accelerator, and on bumpy roads. Sometimes it comes on while on the interstate with cruise control activated causing the vehicle to come out of cruise control. Dealer states it is a common problem and my parts have been on back order since October of 2022, It is now February 19 2023. Dealer states it is a 1400 dollar repair.

My ABS and traction control lights came on my dash. It gave a message to service electronic brakes. The lights would come on, followed by an audible ding. Then it would go off, again with an audible ding. On, and off, on and off again. Sometimes it will stay on, some times it’s intermittent. It happens under all conditions, start up/running at temp, bumps/level roads, during braking/driving at speeds, and in wet/dry roads. The only performance issues I’ve clearly noticed is the traction control not working on wet grass. I’ve had to use four wheel drive to get out of the situation. I’m questioning the safety of my vehicle at this point. I have been researching and see that this is a highly discussed issue and a known issue, and has parts availability issues. I saw where NHTSA had opened an investigation, so I wanted to report that it is also a problem for me. I plan on contacting the dealership this week.

The Service ABS light come on, around 32,390 miles just out of the 3 year/36,000 mile warranty! The cruse control no longer works! The traction control light is on with the ABS light! Beeps on and off and on and on very annoying!!! Had the truck scanned by my local Mechanic. ANTILOCK BRAKES C0020-01 ABS PUMP MOTOR CONTROL-GENERAL ELECTRIC FAILURE-STORED. The truck is available upon request.

The abs module and hydraulic control unit has failed. This means that my safty and others on the road is put at risk because during heavy breaking you can loose control of the vehicle due to the truck anti break system does not work. Also the traction control does not work which also will cause you to loose control.

Vehicles “service antilock breaks” code is flashing. Began doing this with under 15,000 miles. The cruise control and the anti lock breaks don’t operate as a result. Problem started as intermittent and is now a constant issue. It appears to be the hydraulic break control unit, and is a very common issue with this year of truck.

The service brake system and service antilock brake system light came on. This light comes on quite often and shuts off intermittently. The pick-up no-longer has anti-lock brakes, traction control, or stability control. When light is on cruise will not work which if it set and light comes on it will shut-off and cause vehicle to drop speed which could cause an accident. Last time I drove it it felt like the brakes were spongy or not really engaging, which almost cause me to go through stop sign on to a highway. I have not had a chance to take it in to get checked yet, and the parts to repair I believe are back ordered.

Brake ABS and traction control system is malfunctioning due to failed ABS Hydraulic Control Unit as diagnosed by Ram dealership. Malfunctioning includes illuminated warning lights for ABS and electronic braking system. Malfunction also effects use of cruise control system. Vehicle is available for inspection upon request. Safety is at risk due to unknown effects on use of ABS system. Problem has been diagnosed and confirmed by dealer. Warning lamps have been intermittently illuminated for several weeks.

Abs lights on traction control lights on constantly off and on alarming. Making it un drivable Was told it's very common issue currently being investigated by nhtsa. Dealership confirmed HCU Pump control module. Costing me quoted $1750 for repairs and unknown when part comes in. Earliest is end of March. All the forums and videos I've seen that this is constantly happening and this needs to be recalled. I believe it already has on the 2019-2022 models. Safety concern with no abs or traction control. Also cruise control won't work.

Multiple ABS pump and ABS hydraulic control unit failures. Components have been replaced and replaced components failed also after a few months.

ABS and Traction Control system failures. Available for inspection Lack of ABS makes controlling or stopping difficult in the winter, higher potential for collision in slippery conditions. Dealership has confirmed that ABS and HCU modules are cause. Service traction control and antilock brake system messages displayed intermittently starting around July 2022 at 40,000 miles, and then continued until total failure.

Abs and traction control light goes on and off shuts the cruise off. Was told that it could lock brakes up and wasn’t safe to drive. Dealer doesn’t have one and the soonest they were going to be shipped was March 15th maybe.

Abs light blinking on and off while driving and parked.

While driving my truck in the interstate in the rain, I went to change lanes and accelerate to pass a slower moving vehicle. As soon as I hit the accelerator the antilock brake system warning light illuminated and the rear wheels broke traction. The rear end of the truck began to slide and I nearly lost control. I had not had any problems with the brake system prior to this incident. From that point on the service abs/brakes light and alert noise began to activate on and off intermittently and the traction control is inoperable. In doing research this is apparently a known issue with the hydraulic brake control unit. I was fortunate to be able to maintain control of the truck.

The vehicle continues to have ABS control module/electronic braking failures. I was told by the dealer no replacement modules are available, and could be back ordered for up to 6 months. Research online indicates this is a very common problem. This is a clear safety hazard. A recall needs to be issued for these failing parts. I had these parts replaced one year ago and they already have failed again.

The ABS and traction control service lights and alarm come on and off and shuts off cruise control. stops coming on for days at a time then happens again. Been told brakes could lock up and trailer brakes may not work

Abs unit failed during a panic brake situation and I hit a vehicle. No injuries. Parts have been on backorder for months.

System constantly chimes alarm on and off for Service electronic braking system, Service Antilock brake system. The HCU seems to be in short supply because you cannot buy it online or from a dealership they all show out of stock or backordered with no eta of when it will come in. I feel like it only a matter of time before it causes an accident. Seems to be a known issue with RAM. I have a video on my phone of it going off constantly

The abs and traction control and service electronic brakes system flashes on and off. Truck only has 65,000 miles on it now and it start around 60,000 miles.

Multiple reports from 6.7 Ram Cummins owners experiencing the failure of the grid heater. The grid heater failure leads to the destruction of the engine. Ram uses a grid heater to warm up the vehicle during cold temperatures for starting. During this process, it has been reported, that the not of the grid heater melts off and enters the engine causing catastrophic damage.

2018 RAM 2500, both the hydraulic control unit and the anti-lock brake system module had to be replaced with only 46,000 miles. I would get a warning to "Service Electronic Breaking System while going highway speed with the cruise control on. Once I receive the warning, it would disengage the cruise control without any notice. That is very scary and dangerous.

The abs and traction control lights come on and go off intermittently. I took the truck to the dealer they said it need a new hcu which costs 500$ and 1000$ for labor the truck has 27000 miles on it and is out os warranty. The part need is on back order. I feel this is a defect and there should be a recall. Thanks for any help you can give. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

ABS SERVICE BRAKE MESSAGE APPEARS AND CLEARS. THIS LAST 20 MILE TRIP IT WENT OFF OVER 20 TIMES.

Vehicle has had multiple failures of the ABS system. One failure occurred while under warranty at 14,228 miles, but a subsequent failure at 45,994 miles is stated as "not covered" under standard or safety-related warranty. In the first failure, the "CONTROL A 68143491-AA" was replaced. For the second failure, "CONTROL A 68143491-AB" and "Module AN 68347098-AB" are to be replaced. The replacement has not occurred as of this date (3 months post diagnostic) due to a shortage of parts. It is claimed that there are so many failures of these parts and the pass-rate during manufacturing inspection is so poor that a resolution time for my primary vehicle is unknown. The quoted cost of this safety-related epidemic problem is near $2000 or almost 4% of the cost-new of the vehicle.

In December 2022 the ABS warning light came on in my truck. Dealer confirmed that the ABS Module needed to be replaced. My dealer also said that there were several other like vehicles that they were holding onto for the same reason. Internet search revealed that this is a known issue with Ram. The real problem is that the part is apparently on a long backorder. There are reports of people waiting 6 months for the module. I was initially supposed to get the part on 18 JAN but that date shifted to 15 March and the dealer is telling me it's unlikely we'll even get it then. Two issues as I see it. 1- Ram has installed defective ABS modules in its trucks and has no way of replacing them. My truck is a 2018 with only 43000 miles on it, should ABS modules be going bad? Should a vehicle owner have a reasonable expectation that the company will be able to fix/backup it's products? The other issue that really pertains to NHTSA is that I've heard from multiple people that, due to the long wait times for the part, they're simply pulling their vehicles out and using them. Most people (like me) are struggling with being down a vehicle for months at a time. Many require it for work. The brakes still function but the ABS will not (nor will the cruise control). If the reason that vehicles all come equipped with ABS is for safety, it makes sense to me that having vehicles on the road without it is unsafe. But what are people to do when Ram will not provide a part? I'm working my issues with Ra

The ABS - Electronic Braking System fault light flashes on the dash while driving. This could cause a crash during hard braking, rain slick roads, or while towing. The truck has been to the dealership about this concern and was told the parts are not available for at least 6 months. I was also told by the dealership that the manufacture who makes the parts is not longer in business and there is no plans for Ram to source a new manufacturer. The part at fault is the ABS module and Hydraulic Control Unit. These parts were replaced while under factory warranty in August of 2020 with 13,894 miles and needs to be replaced again under RAM's extended warranty with 24,000 miles. This is an ongoing issue with these trucks. I keep getting mixed answers if the truck will pass a state inspection with the ABS light on.

First time brake system hydraulic control unit failed was at 17,000 miles, now have 76,000 and it has failed again. Abs system notification goes off and on constantly. Turbo actuator has failed at 76,000 miles. Check engine light and associated ecu codes are flashing. Rear view camera on tailgate goes out intermittently.

ABS/ESC light illuminated on dashboard to service. Truck at 46k miles with pristine service condition. Truck taken within 2 days to Firestone Automotive and code of C0020-01, ABS Pump Motor Controller General Electrical Failure received. Unable to order parts from dealer, national backorder, believed to be Anti-lock Brake System module and Hydraulic Control Unit (HCU). Service department unable to fix, told to drive it or wait until new HCUs are in stock. Unclear if risk to others while driving truck with faulty ABS module and HCU.

The ABS and Traction Control units stopped working with 23,000 miles on the truck which also caused the cruise control to stop working. This is obviously very dangerous to have the brake system fail. Dealer has taken 8 weeks to get the parts and is costing over $2000 to repair. The dealer states they have never had this however there are many forums / videos on the Internet discussing this exact problem. The 2019 to 2022 RAMs already have a recall for this exact problem while the 2017 and 2018 owners have to pay for it out of pocket.

I have a 2018 Ram 2500 with 68000 miles. Last year while driving the ABS and traction control light came on. The sensor will frequently trip and the code will come in and out intermittently. Upon research, it seems this is a known deficiency with this model. I called the dealership and while they agree it is a known issue, there is no recall so I will be forced to put out the money myself. With labor the cost would be over $1600. I am about to spend over $500 for a new Electronic and Hydraulic Control unit for the trucks ABS and just do the repair myself. Is there any relief at this point from the NHTSA? can we finally get a recall issued? I have seen over 212 complaints on this very website for this very topic. This is only the ones that have found this website and made a complaint. How many more dont know to do this?

Started getting Service Brake System and ABS warnings in July 22. Had the ABS module replaced. Still getting alerts which deactivates the cruise control randomly when the warning appears. Warnings ding randomly and frequently. Apparently the hydraulic control unit needs replaced but the part is not available and can't be ordered now. I'm worried that I will lose my brakes.

ABS SERVICE LIGHT CAME ON FOR THE SECOND TIME. I TOOK IT IN TO THE DEALER THEY REPLACED A PART AND NOW ITS BACK ON AND OFF.
