Service electronic brake system notification turns on intermittently, cruise control does not work during this time

C0020-01. Electronic Braking System and stability control system continually go in and out of alarm kicking the truck out of cruise control suddenly. This was repaired once under warranty by replacing the hydraulic control unit at 40,000 miles and it is now doing the same thing again at 90,000 miles. This is a significant safety issue as it prevents the use of cruise control and turns off the stability control system on the truck. The parts to repair the system are not available due to them being in -??Engineering Review-?? until 2024. The only guidance from Ram was to continue driving the vehicle until parts become available.

ABS warning light goes on and off at intermittent times. Message says service ABS brake system. This truck has not been inspected yet but there is a class action lawsuit and NHTSA investigation on-going for this problem.

Similar to the 2019 & newer Ram HD recall for the ABS electronic control module, my 2018 Ram 2500 has the same issue. It was recently diagnosed at the dealer in August 2023, but due to the abundance of impacted trucks, the dealer estimates that replacement parts will not be available until at least February 2024. While I wait for the repair I have no ABS, traction control, stability control, or cruise control. I drive the truck approximately 750 to 1,000 miles per week and have a 3,000 mile vacation planned in October. This translates to driving the truck approximately 15,000 to 20,000 miles without the above noted safety features. I believe my truck should be added to the recall, and RAM needs to step up and provide faster repairs.

In October 2012, my 2018 Ram 2500 had issues with the brake module and ABS system. The truck had 49000 miles when the system intermittently displayed messages to service ABS system. A trusted local mechanic checked and found a service bulletin about the issue. I had him replace the brake module and master cylinder. I then had a Chrysler dealer reprogram the module. My costs was approximately 800 dollars. Now it is summer of 2023 with 65000 miles and the same issue is occurring. I think it is time for Fiat Chrysler America to step up and make these repairs. It is dangerous to have this situation. It affects cruise control, four wheel drive, and of course negates having ABS. I need this truck and cannot afford to park it.

ABS traction control braking issues and danger. Only has 24K miles garage kept

- Central City, KY, USA

My ABS and traction control dash lights came on and lost cruise control while towing my RV. I fear of someone rear ending me when loosing CC. The alerts intermittently go on and off.

- Belle Chasse, LA, USA

ABS light and traction control light came on. Upon scan tool the code was general electrical failure of ABS system. I call my local ram dealer and they inform me of multiple failures of the HCU on 2017 and 2018 ram trucks. This is a safety hazard for my self, my family, and others. Theis desperately needs to be a recall on the ram trucks. This is very dangerous. Also the ram dealer talks of at least a 6 month lead time for this part.

The abs module and abs pump has failed for a second time. Anti lock brakes do not work or traction control with lights on in dash The message appeared 2 years ago. Bought the parts and dealer fixed it. Now the message is coming up again.

ABS traction control, light code c0034

I purchased the subject vehicle in NEW condition in September 2019. On April 2021 the vehicle ABS lights came on and off. The mileage of the vehicle at that time was 16,538. I took the vehicle in to get serviced by ANCIRA Chrysler Jeep Dodge Ram dealership and the HCU PUMP was replaced. I have the service invoice that has all this information. On August 20, 2023, the same lights came on. The vehicle now has 48,000 miles on it. As a part time mechanic, I conducted a diagnostic test and found that the error code is the same as the initial incident, which is Code C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRIC FAILURE. The vehicle no longer as a warranty and since there are no available parts available for repair, I have no choice but to drive this truck putting myself and my family in danger. The vehicle is available for inspection if needed.

- Corpus Christi, TX, USA

My ABS and Traction control lights activated visually and with audible alarms. I brought it to the dealer. It only has 23,000 miles on it with a manufacturer extended warranty. The dealer told me that the ABS pump motor control as well as the HCU has failed and need to be replaced. They also told me that the parts are not going to be available until the EARLIEST February of 2024. The vehicle is not safe to drive without these safety systems working especially towing. They told me the parts are under Engineering review. They suggested I park the vehicle until parts are available. NOT ACCEPTABLE!!! I have looked at owner forums and this issue is common and needs to be addressed by NHTSA and the vehicles recalled due to safety.

Service ABS system and traction control light continually flashes on and off. Does not allow me to use cruise control and it also turns off my ABS which is unsafe.

Abs HCU failure. This is a know common issue and yet no recall. THIS IS NOT SAFE

- Van Buren , AR, USA

My ABS / Electronic Stability control warning lights keep coming on intermittently and also sometimes staying on for hours at a time. I cannot use my cruise and my ABS will not work with these problems making this a very dangerous truck to drive. I have read that there are many other trucks with this issue. More specficially the 2017-2018 Ram 2500's. I believe there should be a recall for these parts as this is a intergral function in these HD trucks.
