ABS/traction control sensor issue. I believe it to be a faulty sensor or sensor connection issue which is causing my service brake light to chime and light up at every bump in the road. While driving even just a short distance my service brake light/alert chime goes on and off sometimes every 2-3 seconds and while driving on the freeway my cruise control disengages every time the brake warning pops up. Upon researching this issue I've found thousands of Dodge Ram owners complaining of the exact same issues and dealerships are suggesting they know nothing about this problem.

ABS/traction control failure. This also disabled cruise control causing rapid deceleration at set highway speed. Getting repeating chime and check ABS and traction control warning messages. ABS module and HCU were replaced under warranty at under 11,000 miles for same symptoms. Truck now has just over 45000 and read ABS codes indicate that part has failed again. Part seems to be backordered or unavailable from dealers.

My truck has had a recall done on the ABS system. After the recall I had another problem with the ABS system where the ABS and traction control warning lights and chime came on and then off. This condition was very distracting while driving!! It eventually stayed on all the time. My cruise control did not work and I imagine the ABS braking system didn't work. All the time the dealer was saying there were no parts. I found another dealer and had to wait a few weeks and they replaced the ABS HCU and hydraulic unit. This was in 2022. It is now 9/13/23 and it is starting again!!! I am going to take it back to the dealer and hope they finally will resolve the problem. ABS brakes have saved many lifes. This problem needs to be fixed. There are countless concerns on the internet of this problem with RAM trucks, apparently 2017 and 2018 are the most affected. Please put some fire under FCA/RAM and help get this problem repaired.

ABS and Electric Braking System - multiple failures.. 1st time system failed at around 24k miles, was reported and fixed under warranty, 2nd time same system failures at around 76k, same errors and same results.. will have to be repaired under owners costs.. Seems this is a 'known issue with a NTSB" but Ram still not owning the issue.. This part plays a huge role in the safety controls of the truck.. They are designed and built to pull heavy loads and the braking and traction controls play a huge role in the safety traveling of these vehicles..

ABS, traction lights are on and cruise control, ABS and traction control doesn-??t work. Safety issue. I understand that there is a recall on 2019, 2020 models and wondering why the 2018 ram 2500 are not included in the recall.seems like a common problem says the dealership.

- Whitesboro, TX, USA

Reoccurring Electronic Brake System Failure message along with ABS and Stability Control faults, dealer unable to fix due to supply issues. Ram is supposedly waiting on a redesign, but until then I have a safety compromised vehicle where abs and traction control don't work.

- Antioch, IL, USA

For the past month a warning light illuminates and dings continually indicating an ABS failure and need for electrical brake system system repair. I called the local dealer that was rude to say the least and indicated they know this issue which is very common and requires parts (ABS control unit hcu-hydraulic control unit) that are on backorder and will not be available until next year (possibly February or March). They stated in case of emergency braking and particularly on wet pavement or gravel the brakes would fail and the truck should not be driven. I searched the web and clearly this is a widespread problem of a part/system defect. I am left in a potentially hazardous situation wth no recourse and no vehicl to drive. I appreciate any help you can give me and other Ram owners.

An ABS system that was designed to save other people. And your life is now not operating functionably. And putting me and other people in danger. Or else why would they have made it way back in the day? Receiving vehicle message of serve ABS braking system. Code C0020-01. Dodge knows of the issue and needs to recall and repair.

ABS module or HCU bad. Anti lock brakes not working. Cruise control not working. 4WD not working. Caused issue driving with a load when ABS did not engage and almost rear ended another vehicle.

- Mckeesport, PA, USA

Anti-loc braking system, and electronic braking system issues. Modules needed. Ram has back-ordered them for months. There appears to be a class action suit starting, What is NHTSA doing?

- Appleton, ME, USA

My truck is at approximately 35,000 miles. It recently started notifying me that the Anti-Lock Braking System and the Traction Control need to be serviced. While researching, I noticed that there were numerous reports of drivers with the same issue on forums related to Ram trucks. It appears that this is a very common issue that has not been addressed by Ram.

- Orange, TX, USA

While driving on a smooth paved road the service anti-lock brake system and service electronic brake system lights started flashing on and off. This continued for several minutes and then randomly stopped. On my return trip home after about 10 minutes of driving on the same smooth paved road the service antilock brake system and service electronic brake system lights started flashing on and off again. Once again the service lights randomly stopped on their own while continuing driving.

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.

My 2018 RAM ABS warning indicator light goes on and off continually. It started last year but now it's on constantly. I did some research, and this seems to be a very common issue with this model of RAM truck. Unfortunately, the dealership has informed me there is no recall on the item and cost to repair are over $1,000. So I'm driving with no ABS brakes most of the time. With the light and warning noise constantly going on and off is very distracting while driving. Not a very safe problem to have while driving.

- Bridgeville, PA, USA

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.
