2018 Ram 2500 complaints

Received Code: C0020

ABS & Traction control lights turns off & on. Thus deactivating & activating traction control.

I just purchased a 2018 Dodge Ram Crew Cab from Crown Dodge in Ventura Ca. Within 5000 miles of purchase the ABS has failed and my breaks locked up on the freeway! The truck was taken into the dealership and the service department told me that the part was backordered till mid August and to do ahead and drive it the next 3 1/2 months and assured me it was safe. They sent me home with the truck and said it was totally safe to drive but just don’t break hard or fast?! I left with the alarm beeping continuously and drove home. I am supposed to live without a truck for 4 months? This truck was purchased for towing my commercial fishing vessel daily to and from the harbor being used in conjunction with my limited entry fishing permits ie: crab, sea urchin, sea cucumber, lobster and deeper nearshore rockfish. Without the truck I can not launch the commercial boat that weighs approximately 8000 lbs. Dodge should be held to a higher standard for their trucks! Please HELP!

Intermittent ABS/ HCU light coming on again. Equipment once replace around 20k. Possibly cause of inability to properly stop cause crash. On Oct 2022.

The service ABS System light cycles on and off continuously going down the road. Upon calling the dealer it is a known issue and parts have been on nationawide back order for months with no resolution in sight until “at least August”. In the meantime consumers cannot use cruise control nor will the electronic braking system work for a pull behind trailer. Not having the ABS function properly is dangerous and Ram knows this is an issue but cannot keep up with the high demand associated with this issue.

Intermittent ABS, EBS and traction control issues causing spurious warnings and loss of cruse control. The alerts are distracting to the driver, loss of ebs/abs represents safety issues while traveling, as does the loss of traction control and cruse control. Dealer has diagnosed the issue to the respective abs/ebs controllers but reports no parts in inventory and no due date for when they will be available. Formally request NHTSA force a recall to require the mfg to correct the issue expeditiously.

HCU and ABS Module stopped working. My safety along with other people’s safety is put at risk because if the braking system is not working properly, especially in slippery or wet conditions, then I won’t be able to stop when needed, which can lead to a deadly crash. Yes, the problem was confirmed by the dealership that the hcu and abs control module will need to be replaced. However, the parts are on back order and do not know when they will be in stock, which is a terrible problem to have when it comes to somebody’s brakes. The vehicle has not been inspected by anyone since the light came on, except for the dealership diagnosis. The abs light and traction control light pings intermittently. The cruise control stops working when the light pings which could also lead to a crash. Customers should not have to pay for the $1800 repair bill for a Chrysler faulty part.

The ABS control module failed which results in the ABS system not working. I took the truck in for repair in June of 2022 and had the ABS Module and the ABS hydraulic pump replaced. Now 10 months later, I find that the truck is experiencing similar issues. If you have to push on the brake pedal too hard to avoid an accident, the ABS system shuts down and warning lights come on in the dash. RAM dealers will not warranty the labor to replace the parts and now you cannot even get the parts as they are on backorder. So we have a truck with no ABS system working and cannot even get parts to repair it. And we have to pay for the repair a second time after 10 months. This is unacceptable as we use this truck to pull a boat and camper and now we feel unsafe without a working ABS system.

The contact owns a 2018 Ram 2500. The contact stated that on two separate occasions, the HECU (Hydraulic Electric Control Unit) became defective. Due to the failure, the ABS, traction control unit (TCU), and cruise control features failed to operate as needed. The associated warning lights were illuminated. The vehicle was taken to a dealer where the contact was informed that the part for the repair was on back order. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 60,000.

There has not been an accident. Hopefully it won't come to that! This needs to be addressed

Abs not working for a year now. dodge has no parts to fix issue not safe to drive and should be a safety re-call on hydraulic control unit.

The vehicle experiences intermittent fault displays for "electronic brake service" and "ABS Service". This causes the vehicle to suddenly come out of cruise control and slow dramatically. This causes the vehicles ABS safety function to be inoperative reducing the overall braking capability and increasing the safe stopping distance This causes traction and stability controls to be disabled further degrading the built in safety features This was diagnosed several months ago by the dealership as an ABS hydraulic pump problem with no parts availability. The lack of parts has been an issue for months and has rendered my vehicle inoperative. The dealer said this was a common problem and that they had multiple Ram trucks with the same problem. I also checked online and found multiple reports of the same issue across the brand and across the country. This is a significant and costly repair >$800 for a part which is clearly underdesigned for the applicaiton with poor or little reliability.

Anti-lock brake system/ hydraulic control unit has been out for over a year. Paid dealer for part, that is on back order, have to continue to drive vehicle and have no idea when it can be fixed. The lights and alarm continuously go off making it incredibly unsafe to drive because they NEVER turn off and are totally random. I’ve been tolerating this for over a year and was told to file a complaint because many others are dealing with the same.

1. Anti-Lock Brake System Hydraulic Control Unit 2. Possible safety issue with no ABS available 3. Yes evidently the new part needed in "under engineering review". 4. Took truck to mechanic and confirmed the HCU unit 5. yes have warning messages that WILL NOT STOP CHIMING; Service Electronic Braking system; Service Anti-lock Brake System

The ABS light is on, states it needs to be fixed, we were told by our mechanic that this is a known issue. HCU unit fail and throws service ABS light. Cruise control does not work due to this issue. This started last November and are waiting for parts for the repairs. The truck only had around 74,000 miles when this started. Our repairs are going to be over $1200 to fix. This is crazy, Ram should be recalling these trucks and paying for the repairs.

Faulty abs control module and hydraulic control unit

ABS and Traction control warning lights and chime are constantly on-off, on- off. Took vehicle to dealer, diagnosed as brake module. The module was Replaced. The Same condition persists within 20 miles of repair. On return visit to dealer, brakes were diagnosed as brake pump failure. Dealer says the pump is back-ordered for several months latest ETA Aug 2023 for "engineering review." The dealer says the Anti-Lock system "should" default to standard style braking without any anti-skid or anti-spin. The truck seems to drive normally except under very heavy braking where the brakes seem to over-engage without additional pedal pressure. I have seen multiple claims for this same failure on the same model truck. The dealer did not specifically state the vehicle is unsafe. However, the dealer cannot issue a NH State safety inspection for the vehicle while the ABS light is on. This renders the vehicle unusable until the parts are released and available.

No accident YET. My Service ABS light and Service Electronic Brake light have been coming on and off for the past 3 to 4 months. I took my 2018 Ram 2500, (odometer 44,000 miles), to the dealer and they ran a diagnostic and found, ABS Pump Motor Control circuit and ABS Control Module failure. The informed me that they could not order the required parts because they are on national backorder. They also informed me that if I was in an emergency braking situation my ABS could fail and not activate. I had a couple of conversations with Ram corporate and they didn't seem all that interested or concerned about my situation. it is my understanding that the parts, required to fix and eliminate this potentially hazardous safety issue, could take six to nine months before they are available. I don't know what to do. Drive my truck, my only means of transportation, and hope for the best for myself and other motorist's and pedestrians? Or don't drive my truck and not be able to go to doctor appointments, grocery stores etc. I almost forgot to mention that Ram did offer to pay for 1 month car rental. What good is 1 month going to do me when it could take 9 months before the parts required is even available? In my opinion, Ram should pick up the tab for a rental vehicle until this problem has been resolved and pay for the required repairs.

At random times I get a chime and dash lights that say service antilock break system and service electrical breaking system. It wont happen for a week and the suddenly it will chime and flash every 10 seconds until the truck sits over night. I have replaced all abs sensors with no change. I’ve taken it to the dealership 2 times and they wont even look at it because it doesn’t show a code. I’ve read countless people online complaining about this same issue and some who have even had break failures. It’s amazing this isn’t a recall item with the number of complaints and lawsuits I’ve read. Hoping this will help get a recall started as the problem is potentially dangerous and incredibly annoying to deal with. It also shuts the cruise control off.

Check brakes light comes on and covers digital speedometer. Dealership doesn’t know when they can get pump to fix??? Am I to drive this truck with faulty brakes until them?

I HAVE BEEN EXPERIENCING ISSUES WITH THE ABS/HCU UNITS. THE WARNING COMES ON EVERY BUMP AND THE ABS SAYS IT IS NOT WORKING I HAD IT SERVICED LAST WEEK 4/18/2023 AND DIAGNOSED AS THE ABS/HCU NEEDS REPLACED AND WAS ORDERED. UNFORTUNATLEY THIS IS ON BO UNTIL 8/16/2023. I UNDERTAND THE 2019'S HAD A RECALL BUT MY 2018 DOES NOT?

The contact owns a 2018 Ram 2500. The contact stated that the ABS warning light had illuminated on the instrument panel. The vehicle was taken to a dealer and the contact was informed that the ABS module needed to be replaced. The vehicle continued to experience the failure after the repair. The vehicle was taken back to the local dealer and the hydraulic control unit module was replaced; however, the failure persisted. The contact was then informed that the ABS control module needed to be replaced again. The manufacturer was notified of the failure and a complaint was filed. The vehicle was not repaired. The failure mileage was approximately 17,000.

ABS hydraulic control unit has went out with 6000 miles. It’s a known issue to ram back order of part is 6 months. There are lawsuits over this issue. Why can’t we have ram fix this safety issue. Does it take people getting killed to make this a recall?

Abs control Module & hcu failure Below will not let me updat date problem started approximately a year ago.

Electronic Braking system continues to fail. No ABS or traction control when towing trailer or RV.

ABS warning light on dash. Took to dealer, confirmed pump defective. Service manager said part back ordered until August 15, 2023. No recall listed. Vehicle is RAM 2500, milage 11,500 approximately, 2018 model. Other components on truck will not operate as well.

The abs and traction control keep coming on and off. Sometimes the truck will sink the Brake. This is a very common problem that happens on these trucks. This is my second time that it goes out on my truck. First time went out at 40k miles now just went out on 76k miles. They’re needs to be a recall set on this as it’s so common to go out on such a short period of time!

HCU is bad, per dealership. Can NOT order part because of backorder on said part. Light will go on and off.

The contact owns a 2018 Ram 2500. The contact stated while starting the vehicle, the ABS and the service electric braking system warning lights illuminated. The vehicle was taken to the dealer and the dealer stated that the ABS hydraulic control unit needed to be replaced. The vehicle was repaired. The manufacturer was contacted, and a case was filed. The failure mileage 36,600.

ABS light has been intermittently going on and off over the last year. 67,000 miles and it’s not covered under warranty. Dealership is staying I need an entire new module = $1,900

ABS, TRACTION CONTROL, REPAIR ELECTRONIC BRAKE ALERTS HAVE BEEN FLASHING WITH AUDIBLE BEEPING AND AT TIMES REMAINS LIT WITHOUT BEEPING. Putting a load on the engine or hitting bumps on road seems to cause the warning lights and beeping. This has been going on since June of 2022. Vehicle was taken to shop and diagnosed with failing part (electronic abs brake module) Part was not readily available and waited two months for part for repair. Cost $525.00 total. Did not fix problem now repair shop states the truck needs HCU hydraulic brake fluid pump. Its been EIGHT MONTHS no part available. Truck is in need of repair, no parts available and has limited our use of airstream tow vehicle for travel.

Abs brake failure

Hello, my ABS system on the vehicle has failed with only 27,000 miles on this vehicle. Error code C0020-01 Warning system sounds every 5 seconds. It’s very distracting while driving and dealer ship for repair is 2 and a half hours away. No way to disable alarm.

ABS and HCU are in need of replacement parts. Because no replacement parts are available, I have no choice but to drive a Truck with questionable Breaking System, putting me, my family and others at risk, since the brake system is what stops my Truck when I need it to stop or slow down. I use this to tow the family travel trailer as well. This is also very important when brakes are needed to function safely. I have taken the Truck to my dealer of purchase. They completed a diagnostic test and also reproduced and confirmed the problem. The vehicle has been inspected by the manufacturer's dealership Service Dept. The Truck's "ABS SERVICE BRAKE SYSTEM" warning lights and warning tones alerted me of service needed back in November 2022, with just over 36,000 miles. I made an appointment and the dealership serviced my truck in January 2023. Since no parts are available for the repair, I had no option but to pay a diagnostic's fee to have my vehicle released to me, still in need of repairs. The warning lights and signals continue to go off repeatedly whenever I drive my Truck, letting me know that there is a SAFETY ISSUE THAT NEEDS TO BE FIXED!

ABS and electronic brake control warning lights come on intermittently. Dealer diagnosed ABS Hydraulic Control Unit is bad. Code C0020. Truck only has 44,900 miles. Unsafe towing which is what these trucks do.

ABS Module and Service electronic braking system lights come on approx every 3 -5 seconds or stays on continuously. Which results in poor and dangerous breaking performance. Have been told it’s the ABS module and hydraulic servo. Dealer unable to obtain parts from Chrysler.

The hydraulic control box has been bad in my 2018 Ram 2500 since October of 2022. I have tried to order the part through two different dealerships and three times now directly from Mopar, where my order was cancelled. We were originally told the part would be available in December, then March, now it’s August. The ABS and traction control warning lights ding on and off constantly, which is obviously annoying, but much worse- this is our family travel vehicle. We travel with two children and are frequently hauling heavy loads- a large trailer full horses or a 10,000 lb boat. Not having antilock brakes period is a danger, but hauling heavy loads puts us and the vehicles around us at risk.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed with the cruise control activated, the electronic brakes and ABS warning lights illuminated, causing the cruise control to deactivate. The vehicle was taken to the dealer, where it was diagnosed that the ABS module needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 22,877.

Warning lights for "Service Electronic Braking System" and "Service Antilock Brake System" appeared sporadically for 3 days, then remained lit continuously. RAM dealer service advisor said it's diagnosed as a failure of the Hydraulic Control Unit. They also advised that the part is on back order and not expected to be available until August 2023, that the truck should not be driven and that I could try contacting Chrysler for more definitive information. I did contact Chrysler, who assigned a "case number" for future reference and invited me to call back in a week if I had not heard from a case manager. I noted that this is an issue of interest to NTSB and am reporting in hopes that you can apply pressure for remuneration for the loss of use and expedite resolution. Chrysler is not much affected but my family is without an essential vehicle and faces significant expense to accomodate this "known defect."

The antilock braking system warning is on randomly and I have already replaced the electronic portion of this unit. I spent almost $1100. Now I am being told the hydraulic portion is bad and is unavailable because it has been sent back for redesign.

The contact owns a 2018 Ram 2500. The contact stated that the ABS warning light was illuminated. The contact took the vehicle to the dealer and the ABS module was replaced. The contact stated that the failure persisted. Additionally, the vehicle was leaking fluid from the rear differential. The ABS module was replaced 3 times. The vehicle had not been repaired for the oil leaking from the rear axle. The manufacturer was made aware of the failure and opened a case regarding the failure. The approximate failure mileage was 11,000.

The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed and became firm. Additionally, the service electrical braking system warning light was illuminated. The vehicle was taken to the dealer, who diagnosed the vehicle with an ABS hydraulic control unit electrical failure; however, the vehicle was not repaired. The part to do the repair was on backorder until August 16,2023. The manufacturer was made aware of the failure. The failure mileage was approximately 78,000.

Abs light and ebs lights come on randomly. Some days the two lights continuously come on for the entire trip, some days the lights don't come on at all.

HCU antilock traction control unit, warning lights on.

Anti-lock braking system (ABS) module that causes the ABS, cruise control and traction control systems to fail

Intermittent service anti lock brake system and service electronic braking system results in loss of ABS system. The dealer has examined it and recommends replacement of the ABS pump motor and control. $1000! I’m told parts are on back order for 10 months. Must be because of all the failures on other vehicles in addition to mine.

ABS system and Cruise Control cut out on my truck constantly when I’m driving. My brakes have locked up while I was driving in the rain almost causing me to wreck. I’ve seen other people having issues with this and their HCU units in these year trucks. Ram refuses to help me.

At approximately 21000 miles the ebs/ads warning light came on -the dash. After a few minutes it went out and has been intermittent since, (currently at 39000 miles). During the summer it comes on less often than during winter/rainy season (Oregon). That said there doesn't seem to be an outstanding pattern except when it is wet (on roadways). Have taken to dealership where purchased three times. The first two the warning light was off when I arrived and they couldn't get it to come on. On the third it was on and after talking to the customer service representative I learned that it is a pro lem they have had to deal with many times (the service representative AND a service tech told me that Ram has a service bulletin notice on how and what to fix, it is that common). I asked why it isn't a service recall issue since it affects a pretty obvious safety device -BRAKES- they could not answer.

The contact owns a 2018 Ram 2500. The contact stated that the ABS warning light was illuminated. The contact took the vehicle to the local dealer to be diagnosed. The contact was informed that the ABS module needed to be replaced. The vehicle was not repaired due to the parts not being available. The manufacturer had been informed of the failure. The failure mileage was approximately 62,000.

2 nd Time I have had antilock brake system failure. I have driven 11920 miles in 18 months since the last failure. This could be catastrophic should I be towing 10000 lbs of tractor and farming implements
