2018 Ram 3500 Complaint Log

The ABS pump set a code c0020-01 general electric failure. Upon Inspection by a Mopar technician it was found that the pump needs to replaced. Was advised not to drive the vehicle for it was not safe because of the pump failure the abs feature of the brake system might fail. There is only 15000 miles on the vehicle.

While driving the ABS and traction control warning flashes and dings with every small bump that is hit. Confirmed HCU unit by stans garage in Duncanville tx

ABS FAILURE / DEALER WAITING ON PART FOR OVER ONE YEAR

In July 2022 our 2018 RAM 3500 Diesel 4 by 4 truck started having an intermittent alert. Service electronic brake system, ABS, traction control. Cruise control is disabled during this alert. May 2023 the vehicle was taken to local dealer for a diagnostic. They revealed no codes were revealed answer was to replace the ITBM at a cost of 921.00. And the diagnostic charge was 233.00. I tried to contact the dealer for further questions with no cooperation. I started investigating and purchased a code reader at my own cost. The code that showed was C0020-01 ABS Pump Motor Control-Electrical Failure. Much different than the ITBM I was told. Fiat Chrysler Automobiles put out a Case Number: S2005000004 Release Date 04/28/2020 Symptom/Vehicle Issue: C0020-01-ABS PUMP MOTOR CONTROL- GENERAL ELECTRICAL FAILURE Discussion: Basically says to replace HCU first and then ECU if code still active. So, the dealer is aware of the issue and outright lied to me. There is also an active Class Action Lawsuit for this very issue In California Plantiff James Neu. The fact that my vehicle is not in a safe working condition with this faulty part. The fact that the Dealer is lying about which part is defective and would have installed a different part than what they said the problem is. It is very disturbing that an automotive company is treating the safety of their customers so carelessly. The Fact that this is a common and widespread issue and nothing is being done to rectify, appalling. Thousands of vehicles on the road, no parts available. Action needs to be taken. Lives will be lost, severe injury, it can happen to innocent people. Please do something

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

On my 2018 RAM 3500 beginning on Memorial Day 2023, the instrument cluster began flashing with a loud door type chime. The cluster began cycling through messages including Service Electronic Braking System, ABS Failure, and illuminating alarms. Upon testing with a code reader I was presented with the following codes: C0020-01 ABS Pump Motor Control - General Electrical Failure and U0402-00 Implausible Data Received from TCM. Upon internet investigation, I discovered this is not an uncommon problem with several hundred reports available on ramforumz.com and other sites. According to several complainants, the repair for this will cost in excess of $2000 with one complainant stating this has had to be repaired twice as the replacement components are also faulty. This needs to be investigated and frankly needs to be a national recall on these vehicles, it is a lot more dangerous than a tailgate lock issue. I am concerned with the cost, but more concerned that replacing the noted components may not solve the issue in the long term resulting in additional costly repairs.

Starting in May 2023 mu truck has experience intermittent ABS System errors and Service Electronic Braking System service messages. At many times the errors will repeatedly clear and reoccur, sometimes as frequently as once every second or two. Sometimes the error messages come on and remain so for long periods. When in an error state, the ABS system is not functional and the vehicle will not allow activation of cruise control. My RAM dealer has advised that, despite the fact that this issue has been ongoing with RAM trucks for over years, there are no parts available and ETA for a redesigned part has just been delayed 6 months to June 2024. This is a faulty safety system.

"Service ABS"; ABS & Traction Control lights & chimes come on. This is random, sometimes for hours at a time and sometimes for days without. I've researched and have found this is very common with 2016-2018 Ram trucks.

In May of 2023 while towing my boat I got warning bells and flashing lights, alerting me of the failure of the ABS brake system. In a few miles the warning went away. Then came back on, about 12 times in 20 miles. I also lost my cruise control and traction control. I took to the dealer, about 10 times before they were able to have the episode happen. It was intermittent at first but VERY annoying and Unsafe. The ABS system is almost always in failure mode and has been since about August. They order the parts in June, I'm still waiting. I use the truck to tow a car , a 34 foot 5th wheel and numerous other heavy loads. ABS is very important as is the cruise on my long trips. I'm still waiting, no help at all from Chrysler corporation!! Almost everyone I've talked to with a 3500 and larger truck, has had it fail. I'm tired of paying for a vehicle that is unsafe to drive. I want Chrysler to offer to buy it back, offer a good trade or repair. Please make them fix what they sell!!

Service ABS, traction control, ESP, ABS lights come on. Vehicle constantly beeps. RAM dealer says it needs a new HCU/ABS module (on national backorder) and/or ABS pump. Second time this has happened. Vehicle now at 77k miles and it happened all over again. If this is happening regularly then something must be defective with the parts they are putting on the truck.

Loss of brake performance NHTSA action no. PE22012. Intermittent random dash warning “service electronic braking system and ABS”. Loss of cruise control and 4x4 functionality when lit as well as trailer brake control. Started Nov 2022 and currently continues. Will go weeks without problems and then problem will restart. Many issues listed on Internet forums regarding same. This should be a recall before someone towing a large trailer (as these trucks were designed) loses brake functionality due to a known problem and causes severe injury and/or death. Vehicle currently has approx. 45,000 miles. Multiple forum responses on internet have had parts replaced multiple times in similar mileage

The contact owns a 2018 Ram 3500. The contact stated that on four separate occasions while driving at various speeds, the ABS system locked up the rear wheels, causing the vehicle to skid and the trailer that was being hauled to thrust around out of control. Additionally, the contact stated that the ABS, Electronic Brake System, and Stability Control Warning lights were illuminated. The contact stated that the cruise control operated as intended for a short while but then inadvertently deactivated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the ABS module needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 63,000.

ABS braking keeps flashing and brakes are intermittent. The module was replaced by Ford dealer a while back. Truck only has 118k miles on it but continues to be a problems. I have not contacted dealer yet due to the time they take to do anything.

The hydraulic control unit (HCU) and the anti-lock braking system (ABS) module on our truck has been triggering the warning light and bell notification for almost a year & we have yet to be able to get this repaired as the part is supposedly back-ordered (for a year?!?!?) We pull a fifth wheel with this vehicle and any sort of braking component issue is a recipe for a potentially disastrous incident on the road. We try not to drive the vehicle, but sometimes that isn't always feasible or practical. We are at a loss at this point.

ABS module problems. Flashes to check service ABS and traction control. Then goes away and comes back. Been having issue for over a year with no results in fixing

The ABS and Traction lights intermittently come on and blink non stop. Also, a "Service Antilock Brake System" and a "Service Electronic Braking System " message scrolls through the dashboard screen with an audible alarm. The truck was inspected on September 2nd of 2020 and parts 05400701- Control unit, Brake anti-lock hydraulic and part 68143491AA- Control Antilock Braking System were replaced under the manufactures warranty at 20,457 miles by Arrigo Dodge Chrysler Jeep Ram ID 45724. On May 27th of 2022, once again the same parts failed and dealer ID 58821- Massey- Yardley Dodge Chrysler replaced the failed parts for a second time. The milage on the truck was 60,540 at the time of this repair. The paperwork from the dealer shows an ABS Control Unit Internal Failure. Less than a year later, on May 5, 2023 the parts failed once again (3rd time). I took the truck to dealer ID 58821- Massey- Yardley- Dodge Chrysler for inspection and repair service but I was informed that repairs were not available and that this issue was put on an engineering hold for further review since the parts continue to fail. There is no available timeline for repairs. This lack of response from the manufacturer and the flaw in design creates a safety hazard not only for my family and I but for other drivers around me since the truck breaking response is delayed at times.The truck does not break promptly and the cruise control is cancelled automatically. In addition, the trucks slows down when the message comes on in the dashboard. The problem has been addressed twice by two separate RAM dealers but the issue is not the dealer but manufacturer design. At this time (the third time) there is no solution available to address this ongoing and repetitive defect. The problem has not been resolved. I have attached a copy of all the paperwork and comments from the dealers in case they are needed.

I recently purchased this 2018 Ram Dually for work on our farm. After 1 trip all the ABS/traction control/4wd and cruise control wont work. It seems that this a safety issue that ram will not address. I would like to file a complaint that if I had known about these issues, I would not have purchased this truck. It is unsafe driving and with no ABS and cruise control or traction control. I depend on the 4wd in our farming business and not having this has caused me lost income because I simply could not get the job done and had to give the job away to others.

Truck has only 65, 000 miles on it, I’m the second buyer, has never haul anything or hitch a trailer, I’m having this electrical brake system failure ABS, this vehicle is to expensive and new to have early issues on it. ABS Motor Control- General Electric failure. I seem other similar problems reported with same year and same problems.

The contact owns a 2018 Ram 3500. The contact stated while driving 65 MPH with the Forward Collision Avoidance: Adaptive Cruise Control activated, the traction control and ABS warning lights illuminated intermittently. Additionally, the cruise control then deactivated independently. The contact took the vehicle to the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 161,000.

Purchased this truck specifically to tow 14000 lb fifth wheel camper. Two months ago warning chime and “service electronic brake system, Service antilock brakes and Traction Control” caution lights repeatedly activate. I am concerned about towing in this condition if operating on rain slick roads and winter weather. Also the constant chime is a serious distraction. Truck is currently at the dealership for repair. 25000 on the odometer. Truck is out of warranty. These failed safety systems endanger mine and my family’s lives, as well as other motorist and the public.

The ABS and traction control lights come on intermittently on the dash and the message to check the brake system comes on alot. The ABS system doesn't work when the lights are on and they come on alot. This I believe is a safety issue since it came with an ABS system to keep from locking up the brakes when having to brake hard to avoid a collision.

With 13,253 miles, this LT235-80 R17 tire tread started separating making it unusable and unsafe, especially since it was a front tire.

While driving at any speed the abs and traction control lights start flashing and a chime goes constantly. also when this happens it causes the cruise control to disengage without any warning. Also leaving you without abs brakes. I am on my 3rd abs module and 2nd hydraulic control unit and needing a 3rd hydraulic control unit for this vehicle with less than 62,000 miles the first one went out around 16,000 miles and the second at 37,000 miles. This is also my second truck from this manufacturer to do the exact same thing that happened at 30,000 miles and had another one in the family that did it at 7,000 miles. As i research online I find that this a common occurrence and nothing has been done to resolve the issue other than just replacing the parts with new and wait for it to happen again. I am in need of a new hydraulic control unit and am being told that they are on some kind of hold until the earliest date of August and just to drive the truck with non-working safety equipment.

The service electronic brake light freq comes on. Dealer said it brake "module" needed changing and did. they also charged me $800 for it. Vehicle is still making the claim that the elctronic braking system still needs servicing almost imediately after repair.

Frontal collision at 45 mph, totaled truck but airbags did not deploy. The insurance company sent the truck to the auction. My safety was at risk. Not that I am aware of, the insurance company has photos. Inspected by police and insurance adjuster. No symptoms of anything wrong with the vehicle.

The contact owns a 2018 Ram 3500. The contact stated while driving approximately 25 MPH, the "Check Brake System" and ABS warning lights were illuminated. The contact stated that the failure reoccurred intermittently while driving at various speeds. The vehicle was taken to a local dealer, where it was diagnosed that the Hydraulic Control Unit (HCU) needed to be replaced; however, the parts were on back order. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 57,000.

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 one of the independent diesel mechanics. I appreciate your time and attention and anything you can do to help Dodge address this widespread safety concern as soon as possible.

VEHICLE: 2018 RAM 3500 Dually ISSUE: ABS Module failure RESULTS: Loss of traction control, cruise control, and brakes locking up while pulling heavy loads. A constant chiming from check engine light. INSPECTED: By several independent garages can not find replacement module. Willing to let be inspected if need be. CONCERNS: Brakes lock up and loose control,Cause a accident by rear-ending someone, can't use all the functionality of the truck such as cruise control. Iritating chiming sound make long trips unbearable.

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.

No anti lock brakes which causes unsafe braking in acclimate weather which slid sideways as well as almost rear end vehicles ,also causes multiple functions to not work like exhaust brake and transmission issues !

ABS and HCU Warning lights come on and off. Looking around the internet this is a huge Problem. Took it to a local Ram dealer today and was told its a $1600.00 out of pocket cost seeing the truck is just out of warranty (of course) with 37,000 miles on it. Driving with the cruise control on it throws the warning lights on and off and cruise stops working. It seems the brakes are weak too. The dealer also informed us today they could not even get the parts to fix the problem until at least August! We also had to pile another $1500.00 in it a few months ago because the 4wd did not work either.

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.

ABS warning light and service brake system light keep going on and off. Sometimes only occasionally and sometimes constantly going on and off. Service code 0020 indicates ABS computer and possibly hydraulic pump replacement is needed. Truck has less than 36000 miles when this started but it exceeds the 3 years warranty period. Dealers indicate parts are no longer available to make repairs. This needs to be a safety recall with parts available for repairs to be completed. I have had it inspected by an independent service center and they have continuously said parts are still not available since April 2023 when this problem first occurred and was diagnosed. I see many forums and some class action lawsuits online indicating I am not the only one with this issue.

My vehicle is experiencing an abnormal free play in the steering wheel during driving on mountain roads. The steering box will all of a sudden get “light” and over steer in a long corner and has been getting worse, I have had several other friends that have experienced total failure of the steering box and have reported that the problem gets worse over time, before complete failure of steering. My nearest dealer has confirmed that the steering box may need to be replaced but it is not a “recall”! Seems pretty dangerous to me if steering may fail. Many online forums have numerous customers with same issue and had to have steering box replaced for this exact senerio. This is a highly costly repair and my truck only has 73kmiles on it. I feel this is a very serious issue that needs to be addressed by Ram! Especially if they have replaced steering boxes due to this exact complaint. They quoted me over $2500 to replace, but said it was not covered under a recall? I am very nervous driving this truck when this situation has gotten worse and is very noticeable when driving.

I have two warning messages appearing on my dash. Service Electronic Braking System and Service ABS System. Took it to my dealership Michiana Chrysler Dodge Jeep Ram FIAT in Mishawaka Indiana. I was informed that it needed an HCU (hydraulic control unit) and that the part was unavailable because of engineering review until at least August 2023. The work order was closed and i was sent on my way and told to check back at a later date for availability. After a little reading i found that this issue is under investigation and i wanted add my truck to your list of reports.

This is the second time my ABS electronic braking module has failed in this truck. I hope I'm not one of the only owners to complain. I've read hundreds of complaints. This is May first and it's on backorder til August. It's not safe towing anything with the ABS inop.

Rapid intermittent ABS warning light due to a diagnosed faulty ABS module. Module has been replace previously and now experienced second failure. Ram has no replacement parts available and now I am forced to drive with inoperable anti-lock brake system and a continuous warning chime.

ABS lights come on with the traction control light. It also beeps each time you hit the brakes when lit. It has affected my cruise control as well. Sometimes the brake will skip when you hit a bump while braking. I have had the ABS Pump and Module replaced by a dealer on September 20, 2021. It is now doing the same thing and I had an independent repair shop inspect the truck and they found the ABS pump and module defective again. It has only been a little over a year and a half and only about 15000 miles. Dealers and the independent shop both say there are no replacement parts available at this time and it has been a big problem for Ram. I don't feel safe pulling my 41 foot fifth wheel let alone the truck itself if it malfunctions while braking. I am available for questions or inspection if needed.

ABS dashboard light indicating HCU failure has come on twice: 9/10/20, replaced part and repaired system @ 39015 miles. Hill-Kelly Ram, Pensacola Fl 10/4/2022, replaced part and repaired system @ 72619 miles. Forest Ram, Forest Ms. Reported to RAM Customer Care on 9/29/2022. Case#84242447.

ABS warning light came on with warning bell. ABS and traction control systems not function properly, actually not working leaving the vehicle compromised when braking, especially in an emergency situation. The cruise control does not work when this application has failed. This issue has occured

Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.

ABS faulty. No solution from dealer to correct so chime continuously, lights on dash and ABS not functioning. Part on back order with no foreseeable stock date and new parts are not correcting problem anyway, according to dealer. Here are additional notes from web: 2018 Ram 2500 ABS/HCU problem. Code C0020-01. 10/2022 Class action law suit filed in Texas for 2017-2018 Ram 2500/3500. 12/2022 NHTSA open investigation into the 2017-2018 Ram 2500/3500 trucks. 4/28/2020 FCA issues “Diagnostics for this DTC are currently under review. When working on a vehicle with an active C0020-01 and testing leads to replacement of both the HCU and ABS Module, order and replace the HCU first. Do not order or replace the ECU. Follow Service Information to replace and bleed the HCU. Then perform a test drive. If the DTC C0020-01 did not reset- repair is complete. If the C0020-01 did return active, replace the ECU and return the parts to FCA.” However nobody at my dealer has heard of break issues on the 2018 Ram 2500. Common enough of a problem FCA sent out communication with the dealers on how to fix this issue.

The warning light comes on and then the traction control goes off and the cruise control will disengage all at once. There is also no trailer brake assist. This has been verified by a dealer in Columbus, GA. It is constantly going off and on. The warning light and the warning bell are a constant distraction to the driver. The truck was bought and within 50K miles it started. No warning.

My vehicle has under 18,000 miles. Driving down the road, the Service Antilock Brake System error light came on and also the Service Electronic Brake System light - they both started coming on and the bell to the light rang. It did this for the next 6 hours of driving (we were on a long trip) - I did research, and it appears to me, this is an ongoing issue with the 2018 RAM 3500 and people have been replacing parts and it does not go away. The next time I drove it, I had nothing going off. The next time I drove it, a few miles in, it started again. I took it to a RAM dealer, they had nothing on the code reader. Based on all the research I have done on line, it appears that this should be a recall item. I wanted to make you aware. We aren't what the exact fix is (without just randomly replacing parts) and we are not sure if the vehicle is safe to drive.

ABS failure caused cruise control to disengage at 75 mph with another car close behind that almost rear ended m vehicle. Also, ABS failure cases skidding in wet road conditions resulting to near contact with highway barrier.

I HAVE 2018 RAM 3500 THAT KEEPS SHOWING THE MESSAGE THAT I HAVE NO ABS OR TRACTION CONTROL. MY MAIN CONCERN IS STEERING AND BRAKES ARE THE TWO MOST IMPORTANT PARTS OF CONTROL AND THAT THEY ARE COMPROMISED BY FAULTY PARTS THAT YOU CANT REPLACE BECAUSE OF BACK ORDERS AND ON TOP OF THAT WHEN YOU REPLACE THEM THERE IS A CHANCE THAT THEY GO BAD AGAIN ACCORDING TO ALL THE PROBLEMS I HAVE BEEN READING ON FORUMS. THIS IS VERY DANGEROUS AND NEEDS TO BE INVESTIGATED.WE PAY ENTIRELY TO MUCH MONEY FOR A TRUCK THAT HAVE INFERIOR BRAKE PARTS!!!!!!!

ABS & traction control lights go off and on, dealer wants $2600 to replace HCU and rotors. RAM forum has lots of complaints about this. Dodge knows it’s a problem and will not address it. Dealers can then take advantage of customers.

ABS hydraulic control unit has gone out twice in a year.

Electronic Braking System and Antilock Braking System is defective, similar to being described in FCA Case Number S2005000004. This issue also effects the Speed Control System

Related to investigation PE 22-012, abs hyd control module failed truck only has 18,000 miles.
