Chronological view of owner reports
This is related to recall C4B/NHTSA 24V-896. The ABS/ESC/Traction control warning lamps come off and on while driving. The recall states that this issue may cause a vehicle to crash without prior warning.
This is my 2nd NHTSA complaint regarding this issue on my 2017 Ram 2500. Initial online complaint was done on 4/30/2022 regarding the trucks annoying and unsafe warning light indicating “Service Electronic Braking System” and amber ABS warning light. These warnings began on my truck in 2021 when it only had 12,000 miles. These intermittent warning lights and audible “dinging” still persist today at 22,000 miles. On 2/8/2025, I received notification of Recall #C4B (finally) as a result of the class action lawsuit and was pleased to see this development. To date, I, like many Ram owners are still awaiting parts to become available to have them replaced per the recall and am requesting that the NHTSA step in to assist as we all have essentially unsafe trucks on US highways. I believe this should be a priority, given the fact that owners of 1500, 2500 and 3500 trucks often own them to tow trailers (like myself) which leads to additional unsafe conditions on the road. It’s unacceptable to allow FCA US LLC to continue to delay addressing this recall.
ABS/ELECTRIC BRAKING SYSTEM LIGHT... HAD ABS PUMP MOTOR and HCU REPLACED 2 TIMES WITHIN 28 MONTHS AT MY COSTS..LESS THAN 60K ON ODOMETER
Abs light goes on and off intermittently. Caused my truck wheels to lock up in fast stop maneuver. Dealer said ABS module needs to be replaced but there is no recall yet.
ABS and traction control lights intermittently go on and off. Most of the time just by driving over a bump. Constantly going on and off. Many forums online about this related issue. Many talk about pump being replaced and not solving or the Hydraulic Control Module replaced and not solving and many talk about faulty electrical connections. Error code: C0020-01 ABS Pump Motor Control - General Electrical Failure
ABS and traction control light flashing randomly. Causing cruise control to shut off randomly. Caused by faulty ABS modal, and or HCU. This is a know major issue with 2017 rams with parts not even currently available to fix.
Truck has had two ABS units replaced under warranty for the code C0020-01. Now a year after the last replacement the code has come back and needs the ABS unit replaced again. FCA knows there is an issue with these and continue to sell and install parts that they know will fail. This will cause the loss of ABS braking, traction control and trailer braking. Someone need to force FCA to provide a "correct" repair and ungraded parts for this error.
•abs pump motor control general electrical failure •no abs or traction control •yes has been confirmed on a professional scanner •no •no lights until it went bad again Replaced the and/hcu in October of 2020 due to the dtc c0020-01 and all was fixed until June of 2024 and now the same code is back. Not wanting to replace the same part again just for it to go bad in 2 years.
Abs module and pump goes on and off about to put the third one on the truck and only has 74,000 miles
Continue to get Service ABS and Service Electronic Braking System warning lights. ABS does not work when warning lights are on returns to normal when warning is off. no other detected issues with the braking system. It is displaying code: C0020-01
For the second time, my truck is repeatedly having "Service electronic braking system" message appear and disappear constantly while driving. This is mixed with "Service ABS system" message that also repeatedly pops up with a audible ding. The warning lights for traction control and ABS repeatedly turn on and off as well. This happens over and over the entire time while driving. We were on a family trip with our 1 year old when this started again most recently. We had to turn back around, drive home and swap trucks and everything in them as we can not have potential brake failure with our 1 year old in the vehicle. The trucks has just over 51,000 miles and this is the second time this has happened. The first time the truck was under warranty, so it was "fixed" by the dealer. I am no longer under warranty. The part to replace is unavailable online, and from what I am reading may be on a national back order with the dealers (I left a message with my dealer who fixed this last time under warranty- have not received a return phone call yet) The last time this was fixed I was told it was the ABS HCU which was replaced. I have looked this up since and learned that this is a known/common issue for the 2017-2018 HD Rams.
My truck has a failure of the ABS system to include the cruise control. This failure has resulted in the brakes locking during slick conditions and the vehicle to slide. I was not going fast so there was not crash. My truck is showing a code coc0020-10 (ABS pumpmotor control-general failure). This failure was repaired (replaced the HCU) by the dealership on 10/06/2020 and this temporarily fixed this issue. In 2022 this issue started again, and I contacted the dealership and was referred to Ram customer support. Ram customer support told me that the HCU was under engineering review and the review should be completed by Aug 2023. At last check there has been no new part number to replace the defective parts. I feel this issue should be fixed with a mandatory recall.
We too our 2017 Dodge Ram 2500 to Lenoir City Chrysler Dodge on January 11, 2024 because the Antilock Brake System (ABS) and Traction Control warning lights were coming on. The truck was in the shop for about a week. We were told initially that the part (electronic control module) was on order. Then we were told that the part was under redevelopment and that they did not have a date for when the part would be available. We do not know if the truck is safe to drive or not so we have not been driving it. All we want is to purchase the part so we can use a truck the cost us $43,000.
Traction control and ABS lights flicker on dash cluster. Possible ABS module failure. Parts on back order, I believe this is a safety hazard that needs to be corrected by a recall. This is a known issue that has yet to be resolved since 2017. That's unacceptable.
Abs pump failure on a vehicle with 80k miles.
At approximately 101,000 miles, the service Electronic Braking system and service Antilock Braking system warnings began showing up intermittently on the dash. I have taken the vehicle to a dealership and have been quoted between $1,500 and $3,000 for repairs once parts are available, with a 6 month wait for parts. I was notified that parts had become unavailable in the second half of 2023. I have lost cruise control and slight braking performance due to this on top of the nonstop annoying dinging going on.
ABS and traction control light. Continue to flash on and off cruise control will not work when light is on and traction control does not work. One light is on. I Heard there is a class action lawsuit in California trying to have my vehicle fixed. It continues to beep whenever I hit a bump or take a turn. Sometimes it's on. Sometimes it's off
Picked up my truck from the dealership and my ABS, and traction control light came on, and i lost my abs function and traction control. The my dash started flickering and it would go in and out. Now my heat also has stopped working. Truck is saying service abs system, service electronic braking, service rear park sensor. I do not feel safe in this vehicle as i did my research and see how many vehicles have been affected, i cannot believe Ram has not done a recall as with out my abs i almost slid off the road as it was icy out that day and i was unaware my abs would just stop like that.
Vehicle has about 60,000 miles. Has started intermittent service electronic brake and service abs warning. Noticed alot of information online that this is happening more than a normal rate of failure. I believe where this is being looked into...hoping for a speedy response. Thank You!
The Service Antilock Braking System warning and Service Traction Control warning illuminate regularly. There are no known problems with the systems but it is unknown if they will work when needed. The lights come on up to one time per second, and sometimes not for days. There are hundreds of people on forums complaining about this, no known fix. Replacing components does not seem to solve the issue. I have video available if needed.
My 2017 Ram 2500 has the ABS and HCU issues commonly found on these vehicles. To my Suprise the dealer cannot get the part due to how common this issue is the parts are on backorder. I have videos of the system failing while driving and the codes it is throwing. Due to it's tie to the ABS I do not think the truck is safe to operate. I am still making payments so this is a big deal for me. I can't trade it in for a couple of reasons. One of the main ones being I will have to take less money due to this defect. Yes, it has been reproduced by a local service center and I have video of it malfunctioning on the road. Inspected by a local service center but not a dealership yet. The warning lights come on and it "dings" at me.
Failure of ABS pump module and ABS electrical connection has taken place and is available for inspection. This failure has caused failure of my ABS system, traction control system as well as my ability to use my trailer brakes when hauling which I have to do on a regular basis which in turn puts all drivers around me in danger as well as myself and any passengers I have while driving. Problem is repeated on a fairly regular basis however I am unable to know when it will or will not occur. It has been looked at by a service center with codes sent to local dealership who stated “those parts are under engineering review and are unable to be ordered through normal procedures” however he stated he would be able to put in a special request to Mopar to get one of the “under review” parts sent to his dealership. Vehicle has not been inspected by anyone other than my local service mechanic. The problem has been associated with alarms, abs lights, traction control lights and multiple messages on my dash board screen hundreds of times while driving long distances.
