2018 Ram 3500 complaints

ABS error code on truck approximately April 2023. Had tested at Dodge dealership in Marshall where they determined it was the ABS controller that was bad and had to be replaced. They informed me that this would not be available until August of 2023. This would mean that my anti lock braking system would not function properly for several months. I contacted two other Dodge dealerships in East Texas as well as an independent diesel mechanic who confirmed the same thing - this part would not be available until August 2023. I had Marshall dealership to put my name on list with others who had the same issue, and I had to continue driving the vehicle with the ABS system compromised, with the awareness and care knowing that this is a safety concern. August 2023, had not heard back from the dealership so I called and asked about the ABS controller issue. They told me they had been notified by Dodge that this part is not available in August and they had no expected date for it to be manufactured and available for these repairs. I Confirmed with other dealerships and two independent diesel mechanics. It is now mid September and I am having to continue driving with safety compromised due to the bad ABS controller and Dodge not doing anything to address this situation for me or what I understand are several others. No doubt, if they have not already happened, there will be accidents due to the extended time of ABS malfunction on RAM trucks. I am now reaching out to NHTSA as the urging of

Abs and traction control lights are on. Cruise control will not work when lights are on. Lights go on and off with chime very annoying. Brakes will not function properly when lights are on. Contacted dealer no eta on parts. Almost 2 years now. Contacted dealer before warranty was out. Next time I went to ask I got another service rep and he said my warranty is out. This is not good.

ABS LIGHTS COMES ON ANTI SWERVE LIGHTS COME ON HCU MODULE FOR ABS SYSTEM BAD THESE ISSUES ARE NATIONWIDE IN RAM TRUCKS ..parts are hard to get . Dodge should recall I’m paying out of my pocket.

Abs light service system

Intermittent Anti Lock braking system failure messages. From my understanding this is a very widespread engineering/ components failure. This is a huge safety issue and a recall needs to be issues. RAM was allowed to build trucks for years that had major steering issues, now the brakes don’t work properly. The NHTSA needs to hold them accountable.

I am getting a warning on this dash telling me that I need to "service electronic braking system". When this message comes up I lose my ABS brakes, cruise control and I get a traction control warning light. Sometimes this will stay on for weeks and then go off for a day and start all over again. When the road is wet you have to be careful with the brakes. I went to the local dealer in Bryan, TX and showed him the warning lights and he told me that I had a bad sensor in the truck. The cost could be as high as $1500.00. The dealership told me that they repair on an average (2) two trucks a DAY foy this PROBLEM. I had the truck checked for any codes in the system and the tech told me that I did not have any codes but yet the tech could see both warning lights on my dash. ABS light and Traction control light.

When operating the vehicle the Service ABS/Traction control light starts flashing and cruise control becomes disabled while driving. ABS and traction control becomes disabled. Safety issue! Advised the part will not be available until Feb 2024 and to operate vehicle as is.

What component or system failed or malfunctioned, and is it available for inspection upon request? On July 28, 2023, while travelling Northbound on Hwy 287 N, the engine brake automatically engaged without depressing the brake pedal or decelerating. Prior to this, there was no indication of any problem. No messages or warning lights appeared. I notified Karl Klement Dodge in Decatur Texas to inquire about braking problems or recalls affecting this model. I was told that I had no recalls, and they were unaware of any similar issues. On 9/11/23, after travelling approximately six miles, the ABS and traction control yellow warning indicator light illuminated and an audible warning ding initiated. These warning lights came on and off at recurring intervals, on multiple occasions. Eventually, the service ABS system warning initiated on the center control panel. At this point, I had driven no further than 8 miles. I proceeded to an independent service center in Bridgeport, Texas and spoke with a certified mechanic. He did a computerized diagnostic which indicated the HCU/ABS Module system was showing to be defective. The mechanic stated that they have had to replace this item on other vehicles recently. I again notified the Karl Klement Dodge dealership to inquire about my warranty or a recall or any other problems relating to the ABS or other braking system components. I was told that it would not be covered under warranty, and that there were no problems with the braking system o

Antilock brakes Malfunctioning dealer Says Wont fix it under extended warranty Does Not allow antilock brakes to function properly

ABS and Traction Control lights intermittently comes on and then will go off after a few minutes and "service electronic braking system" message appears. This may happen 25 times in a 5 mile trip and the next day not do it on a 30 mile trip. DTC C0020-01. Safety issue since ABS not working correctly and parts are very difficult to find. This is an on going problem, not a one time occurrence.

Already had hcu replaced once now its bad again this truck never goes off road the first time was at 9953 miles now the second time 30550 miles these parts are not even available there has to be something done there no excuse for this to happen. So many complaints about these parts we need a recall

The "Service ABS" warning light randomly started coming on in the dashboard display. Sometimes it alerts every few seconds, other times it may not alert for days. When this happens I experience a loss of anti-lock brakes, traction control, and cruise control. This truck is used to pull heavy loads and the random loss of anti-lock brakes is not good. My local dealer says that parts are on on back order for many months. The potential loss of braking is scares me and is a danger to others around me. Yes, the vehicle is available for inspection.

I TRY NOT TO DRIVE TRUCK AT ALL EVEN DEALER SAYS TO DRIVE IT WITH NO ABS OR TRACTION CONTROL.

ABS module has been replaced 2 times after factory modules have failed. I now have a 3rd failure and Ram says unit is under engineering review. 82,000 miles on truck.

Abs light on repaired under warranty once now back on again truck only has 20000 miles but out of warranty light has been on for about 3 months dealer said no parts till 2024 dodge is changing the parts to fix this is what they are saying so they new original parts replaced with new but same parts was not fixing problem they should issue a recall it is totally their fault

Auto brake anti skid components failing creating unsafe brake operation while towing a 15,000 lb trailer. Dealer states parts won't be available for at least 18 months. This is a hard fault and can't be reset.Dealer states this is a high failure item on these trucks.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and been replaced multiply times on my vehicle. I have the current failed part available for inspection upon request. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The problem has been reproduced by my local dealer twice both with the original part and its' replacements. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message.

Since purchasing this truck brand new in 2018 we have had nothing but problems with this vehicle. Dodge Ram failed us every time. They failed to work with the dealer and ignored every attempt to find solutions. It started with vehicle loosing power on very dangerous locations a specially freeway located in curves in the middle of nowhere. It took years to fix that problem. Multiple times we drove from the shop being told that it was fixed and it wasn't. We would drive right back in after 15 min. It took over 3 years to get dodge and dealer to replace the transmission and all electrical issues. The other problem that we have had since buying this truck is the AC. Its been always a problem we are continuously trying to fix it and its been very hard. This entire summer my children have been suffering. We are driving in extreme heat with zero ac and Dodge Ram can not produce part for the dealership to fix it. What is really unfair that original dealer tried again to charge us for something that it waste the problem. We would have paid for it and would have been back within an hour. The new dealer Peterson Dodge understood the problem and was honest with us that there is a lot more then a filter. It was me who requested to get a second opinion and get a way from Larry H Miller Dodge.

The service ABS braking system warning flashes on with a chime frequently when driving. This started 3 weeks ago. According to the Ram Forums this is a common problem with 2018 trucks. My truck is a 2018 with 352623 miles on it and according to the Dick Hannah dealership a part that is out of warranty. There is no replacement part since the original inventory was all pulled back from the dealerships to the manufacturer due to the incidences of failure. This information was given to me by the Dick Hannah parts manager. He said a newer more reliable version of the brake module is being built but replacements are not expected for at least 4 months. Ram knows the part is and was defective, i am out of warranty and have a dangerous truck to drive for the next 4 to 5 months then a estimated $1500 repair bill. I want Ram to pay for this and to expedite the replacement parts and the NHTSA to do their job and serve us the consumer instead of the manufacturer. I am seeking legal recourse too. I attached the repair code report derived from my Blue Driver code reader tool.

Sep 2020 purchased 6 Cooper Discoverer AT3 (LT235/80 R17) tires to replace OEM tires, mileage 12,885. On/around Sep 2022 while towing a 38' 5th wheel trailer, front end of truck started bouncing, mileage 26,334. Both driver and passenger tires where found to have tread separation. Replaced those two with same make/model new tires. All other tires where rotated and balanced. New tires went to inner rear wheels. On/around Aug 2023, once again while towing large 5th wheel trailer, front of truck started bouncing when turning to the left, muted vibration when turning to the right. Tire shop found passenger front tire tread separation again. This was one of the orginal 6 from 2020, mileage 33,762. Since 3 of the 6 tires failed I replaced all 7 (spare included) Cooper tires at my expense.

ABS failed during a panic stop causing the vehicle to skid. Received a notice on the dash to “Service Electronic Braking System” followed by the ABS and traction control lights coming on then off a number of times. It is my understanding that the Hydraulic Control Unit has failed, and FCA is aware of this issue. Failure of ABS in a large heavy pickup truck is dangerous, and FCA should issue a recall to repair the affected units.

The contact owns a 2018 Ram 3500. The contact stated that the ABS and brake warning lights was flashing on the instrument panel while driving at various speeds. The vehicle was taken to a dealer where a diagnostic test was performed; the diagnostic showed a faulty computer module had caused the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 44,000.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS and traction control warning lights were illuminated. Additionally, the Service ABS and Service Brake Assist messages were displayed. The vehicle was taken to the dealer, where it was diagnosed that the hydraulic control unit needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 64,826.

The code C0020-01 ABS Pump Motor Control - General Electrical Failure popped up. This happened with 53172 miles on the odometer. Looking on the Cummins Forum, this happens often to the 2017 and 2018 Ram 2500 and 3500 pickups.

I purchased my 2018 Ram 3500 new, in July of 2019. Since then, the HCU/ABS Module has failed 3 times. The first occurrence was at 4391 miles, the second was at 24768 miles, and the third, was yesterday at approx. 45000 miles. The "Service ABS System" light goes on and off intermittingly, which shuts down cruise control and other electrical components. The brake pedal at times feels stiff when brakes applied. This repair is close to two thousand dollars. I've read the other complaints while researching this issue. Something needs to be done by RAM to correct this safety, and excessive cost to owner issue.

Anti lock brake service light came on repeatedly and vehicle was taken to South County Ram dealer in St. Louis and they scheduled a service appt in July 2022 and they indicated an antilock module was required and did not have part due to manufacturer and did not know when part would be available. The vehicle again was taken to same dealer on July 10, 2023, and same story. This was reported to Chrysler Complaint line that same day and no response from manufacturer. How can an important safety part not be available? How can they continue to produce vehicles and not have replacement safety parts?

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated, and the cruise control became inoperable. The vehicle was taken to the dealer and the contact was informed that an unknown sensor needed to be replaced; however, the part was not available. The manufacturer was made aware of the failure. The failure mileage was approximately 20,000.

When driving at Interstate speed of 65 MPH pulling my goose neck horse trailer the instrument panel started dinging and indicated "Service Electronic Brake System", "Service Antilock Brake System" and the Cruise Control stopped working. I slowed and continued home with warring alternation with "dings" every few seconds. I took vehicle to local Dodge Dealer (Blaise Alexander Lewisburg PA) on 08/10/23 who checked the truck and said I needed the HCU replaced. (Code: 0020-01) I had to wait a few days to get the part. Truck was returned to me on 08/15.23. Invoice Number CHCS26809. Total Cost: $843.75

C/S ABS Light on. General Electrical Failure of ABS Module, Hydraulic Control Module resulting in unsafe braking. Un useable traction and cruise control. This has been confirmed by Dealer with no replacement parts. An unsafe braking system experienced in wet conditions with sliding and skidding accrued. Indicator lights accrued intermittently at apr06252023ox 34000 miles. Now on constantly at 60000 mile beginning at 55980 miles.

Bought truck brand new in 2019. Around 16-17,000 miles, I had to replace both front tires, the steel belt had shifted inside the tire causing a bulge and making the vehicle vibrate severly while transporting 3 horses (Approximate trailer w/ horse weight = 14000lbs). I brought back to the dealership, replaced with the same brand as I was unaware of these issues. I now have 36,000 total miles on my truck and about 19,000 miles on this new set and the issue just occurred again. There is something wrong with this brad of tire that these belts continue to shift inside the tire and will eventually cause larger issues. When the event occurs, everything inside the vehicle begins to vibrate and no question impacts the suspension components.

I have a 2018 Dodge 3500 with 9800 miles on it.. The ABS light has come on reflecting a braking and control problem. This also shuts down the safety system within the brakes, shuts down the 4 wheel drive and cruise controls also. It is my understanding from the dealership, there is a problem with the parts within this system, and they can not get any parts released to them for repair. They also don't want to use the same parts, knowing they will only fail again. Which would fall back on them, as a repair faciality. Why hasn't the NHTSA ordered a recall on these vehicles. There are Law Suites also addressing the ABS failure and many complain on this safety failure. I see there is a recall regarding tailgates issue on some of the dodge products. Clearly the braking systems must a higher priority. We should not be required to pay for these repairs. I paid $ 70,000.00 plus for my truck!!! Now they cost in the mid $ 80 K I want feed back from the NHTSA regarding there actions, on the Dodge ABS failure. You ask a question below regarding "WAS THERE A CRASH" in this case it was a near crash. Yes I alive, due to my agility to control the vehicle only. I'm 65 and drive vehicles prior to ABS, so this played into my abilities to control the vehicle. It is now a Federal Law that all vehicles be equipped with a ABS system.. ONE THAT WORKS CORRECTLY. My truck is due a annual safety inspection by the end of this month. Its unsafe to operate my truck, and it must remained park in the garage

The contact owns a 2018 Ram 3500. The contact stated that while driving 65 MPH, a vehicle abruptly merged in front of him causing him to crash into the rear of that vehicle. The ABS warning light was illuminated. The contact pulled over to the side of the roadway and became aware that the brake pedal was difficult to depress. The vehicle was not taken to a dealer to be diagnosed or repaired; however, the dealer was contacted by phone. The manufacturer was made aware of the failure and informed the contact that there was a freeze on the repair due to parts not being available. The failure mileage was 9,800.

ABS and hydraulic module going bad. While driving down the road truck with say service ABS System and hydraulic brakes. Took truck to repair shop to have wheel speed sensors checked by a scanning machine and informed me that the ABS and hydraulic module is going bad.

ABS module failed

ABS warning light came on, this also shuts down the cruise control system. ABS traction control is inoperable, my understanding the problem is the ABS/HCU pump/Module.. I only have 9087 miles on this truck. It’s a Dodge 3500 Dully. I garage keep and baby this truck, as I paid a lot of money for it. It is my understanding, based on all the internet feedback, that this is a major safety issue and NHTSA is dragging there feet, on ordering a recall.

Have intermittent ABS warning and service electronic braking system. This has happened numerous times in the past 10k miles. Scanning the system shows electronic brake failure. This involves replacing the HCU. I have read of others having this problem I can fix this myself but the parts are discontinued or not available. This seems unusual considering it is only 5 years old. My concern is I pull multiple heavy trailers as part of our business operations and having the ABS Warning light on eliminates the trailer brake function of the truck which could cause an accident in event of the need of heavy braking without functional trailer brakes. This problem has been off and on since truck was purchased in March 2023.

INTERMITTENT "service electronic brake system" light combined with traction control loss light. When this happens the cruise control is disabled. Local dealerships have no parts available to repair situation.

Have intermittent ABS warning and service electronic brake control. This has happened numerous times in the past year. Scanning the system shows electronic brake failure. This involves replacing the HCU. The truck has just over 15k miles but is out of warranty due too the year. I have read of others having this problem I can fix this myself but the parts are discontinued or not available. This seems unusual considering it is only 4 years old. My concern is I pull a 14k lb fifth wheel and having the ABS Warning light on eliminates the trailer brake function of the truck. My main concern is why Stellantis has not addressed this issue.

The Automatic Braking System (ABS) and Traction Control lights come on intermittently. They flash and and sound at random. A RAM dealer stated the lights must be on for them to get a proper code to determine the problem. This is an extreme safety problem that could occur at anytime ABS and traction control may be needed.

My Hydraulic Control Unit for my ABS has failed this is the second time in 24 months it has failed and needing service. The part is on backorder and it seems to be a major known issue by the manufacturer with repairs costing near 2k dollars to the consumer because Ram does not want to cover it under warranty.

ABS Pump motor control - General electrical failure that causes the warning lights on the dash to illuminate and an audible chime. Occurring sometimes several times in a row, which distracts operator from safe operation of the vehicle with flashing dash warning lights and audible chimes, affecting in the operation of ABS SYSTEM if required for safe emergency stopping in an emergency situation. Yes the problem has been diagnosed by a dealer ECU: ABS, CODE: C0020-01, DESC: ABS Pump Motor Control- General Electrical Failure The Manufacturer has and is aware of the batch of failed components as per various website forums. And dealer says the components for repair are unavailable for sometime. Uncertain exactly when warning lights started to flash generally, October 2022

ABS and Traction control lights on. ABS Code C0020-01 ABS pump motor general electrical failure. See you recently posted some information regarding 2017-18 Ram 2500 -3500 trucks. Lots of complaints on Ram Truck forums. Lots of problems with HCU and ABS Contollers. SHOULD BE A RECALL. No braking problems...(yet)

Eight months ago I got a "Service Electronic Braking System" warning in the Instrument Cluster. After a brief Google search it was evident that this was a common issue on these RAM trucks. After some diagnostics I determined the ABS Module and/or the HCU to be faulty. After 3 months of calling Ram dealerships in nearly every state I was finally able to locate a new ABS Module, but the HCU has been on backorder country wide for over a year now. I was recently advised by a RAM dealer that the sale of new HCU has been halted until Feb 2024 while RAM performs an internal investigation into the cause of the faulty units. The ABS, Cruise Control and Traction Control features are disabled while this fault remains. While the main vehicle brakes still function properly, the lack of ABS and Traction Control can pose a risk while driving in lower friction environments (i.e. snow, ice, rain, etc), or while hauling a trailer. RAM is not covering these parts under warranty nor is there has any type of safety recall been issued by RAM. The consumers are having to come out of pocket for these repairs (when the parts are available).

HCU module failed. ABS module failed.

C0020-01 ABS Pump Motor Control - General Electrical Failure Under Warranty by FCA Extended Warranty Unable to order part until after 2/21/24 Unsafe to drive with issue and cruise control is inoperable Dash continues to beep while driving which is also very distracting

While driving in heavy rain a car in front of me slammed on their brakes, in response I applied mine. Instead of the ABS engaging, the rear wheels locked up and started to slide, which caused the truck to start to slide sideways on the rain slick road. Fortunately, I had maintained sufficent distance between myself and the car in front of me and there was no accident. Also fortunate was the fact no other cars were around me when the vehicle started to skid. Once I got stopped I noticed the ABS and Traction Control lights were now illuminated on the dashboard. Later that day I had the codes downloaded and received a C0020 code. Which indicated an issue with the HCU and ABS. After reviewing this issue online, I discovered that this is a know issue to FCA and the NHTSA and that many complaints have been reported concerning this issues, including a document from FCA (Star Online Publication: Case #: S2005000004) which is also on the NHTSA own website. There is no system on a vehicle more important than the braking system! Knowing the number of occurrences of this issue and possible severity of injury or even death that could result from this issue, why has the NHTSA not issued a recall for the vehicles? The NHTSA knows of this issue as evidenced by the STAR publications (now at revision C) posted on your website! Please do what your agency was chartered to do, hold the manufacturer of these vehicles accountable for fixing an obvious safety issue! I was lucky, I was not injured, n

ABS and Traction control lights on/off intermitantly. ABS Code C0020-01 ABS pump motor general electrical failure. See you recently posted some information regarding 2017-18 Ram 2500 -3500 trucks. Lots of complaints on Ram Truck forums. Lots of problems with HCU and ABS Contollers. SHOULD BE A RECALL. No braking problems...(yet)

ABS System flashes on and off that it needs to be serviced, also cruis control doesn’t work. Took it to dealer to get it diagnosed. Dealer says the HCU needs to be replaced and the ABS pump needs to be replaced and also that cause the brakes and rotors to wear out and they need to be replaced too.

I was driving on the interstate highway. While driving at 60 mph towing a fifth wheel RV the front end shuddered for several seconds. Then the drivers side front wheel assembly broke off at the wheel studs. I was able to safely get to the breakdown lane. The drivers side front wheel assembly struck another vehicle traveling the oncoming lane. I was told that the vehicle that was struck was totaled. The police on scene documented the incident. The insurance representative has been notified and approved the repair. The collision repair facility documented. I also have pictures indicating broken front wheel studs.

ABS/Electrical Break Control fault code C002001, a known issue with the 2018 Ram 3500, occurred at 26,000 miles rendering cruise control, traction control, and trailer brake controller inoperable. Repair parts are unavailable currently and is not covered under warranty due to age of vehicle.
