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

- Stilwell, KS, USA

On my truck my ABS and traction control light came on as well as a message that say to service ABS system. The parts are on back order for a year now. This problem has surfaced on many Ram 2500's. I contacted the dealer and they don't have parts to fix if. When driving in wet conditions especially while towing a trailer the wheels lock up while breaking. I've been towing going down hill and have had to use a combination of engine breaking, downshifting and feathering the brakes to slow down. Chrysler Fiat should issue a recall on this issue since it happens to many Ram 2500. This started when I had only 38k miles on my truck. Chrysler fiat has issued a recall for the 2019+ trucks but not the 2014-2018 which have the same exact problem. I'm hoping you can help this matter.

Brake error and traction control error on dash. It is available for inspection. Not sure if it is safe but we have not options. This started several years ago. We have looked at ordering parts and tried to make appointment at dealer but parts were out of stock. We have not ever taken it in to the dealer as this happened literally 2 weeks after our warranty expired. No one has inspected it. There were not any other warnings prior and the vehicle seems to function but it is annoying driving it as the warning goes off all the time. I know they recently recalled newer Dodge Rams for this same type of issue but seem to be refusing to recall the older models for those of us that have been waiting and hoping nothing safety wise happens. It is a well knows issue and there are class action suits in other states.

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.

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.

The contact owns a 2017 Ram 2500. The contact stated that the Service Electronic Braking System warning message had appeared on the instrument panel. As a result, both the remote electrical start and the cruise control features failed to operate as needed. The dealer acknowledged the failure but informed the contact that the part needed to repair the failure was unavailable. Once the part became available, the contact was given an estimate for the repair. The manufacturer was also notified of the failure and agreed to cover for part of the repair; however, once the part became available, the manufacturer no longer offered any financial assistance. The vehicle had yet to be repaired. The failure mileage was approximately 52,000.

The ABS and Traction control lights began to flash and the alarm began to come on intermittently in 2021. I took the truck to the dealer for repairs because the ABS, Traction Control and Cruise Control were not working. The repair cost was $1,00 at my expense. The problem has recently returned and is going to need repaired at my expense again. The ABS system not working causes a safety concern with stopping the vehicle. This is a know issue with these vehicles as such I feel it should be the manufactures responsibility for repairs.

ABS, electronic stability control and speed control not working. Code C0020-01 ABS Pump Motor Control.

- Huberheights, OH, USA

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.

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

ABS and traction control light came on, when faults were pulled, active fault # C0020-01. After contacting dealer, Service department stated it is due to faulty ABS module and Hydraulic control unit in 2017 and 2018 models. Parts are on national back order with no available ETA.

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.

ABS, Electronic control system malfunction. Constantly failing causing safety to driving.

- Ridgefield, WA, USA

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!

A Hydraulic Control Unit malfunction resulting in multiple warning lamps flashing on and off intermittently - including the ABS, the EBS, the Traction Control, and the Cruise Control. This is apparently a known issue with this model year truck and is inclusive of a class action lawsuit, yet there has been no recall. This failure results in unpredictable breaking and/or the ability to break and operate, especially in slippery conditions. This replacement repair is estimated at $1,100-1,300 on top of incredible uneasiness to operate the vehicle.
