    Abs and traction control continues to fail. I bought all new sensors. Then replaced abs module and pump and lights went away, after a year they all came back on and it's a repeat process.

    The alarm light and bell goes off. The 'Service Antilock Brake System' and 'Service Electronic Braking System' lights flash. This occurs intermittently while pulling a 5th wheel camper. The brakes work @ 30-40% strength. This is a safety issue. We thought it was an issue with the campers breaks, however, after connecting it to another trailer, the same thing happened. We had to take it to the dealership with a trailer to get it to repeat issue so that they could determine what the issue was. The Dealership ran a Diagnosis on the truck and the DTC, Diagnosis Trouble Code was C0020-01 ABS Pump General Failure. The dealership recommended replacing the HCU, Hydraulic Control Unit. They did not have the part and said it was on backorder. The unit costs $830.49. This doesn't include labor.

    Abs warning light indicator is on. Dealership says abs module and pump have to be replaced, but parts are not available. I've been waiting since Nov of 2023.

    Originally had a warning light show on the dash that said electronic brake system failure and an ABS warning light. Spent over $800 to have this problem repaired and in less than a year the part failed again and same problem occurred. However, his time due to price increases the repair will cost over $1200. When this happens you lose your ABS brakes as well as the ability to operate the cruise control. This is a known safety issue with thousands of trucks affected and Ram refuses to address the problem other than to charge the consumer to replace a part which will knowingly fail again. Even worse, according to my dealer the part isn’t currently available and their recommendation is to not drive the truck until the problem is fixed because the ABS brake failure is a huge risk/liability. I would really appreciate you looking into this matter and please contact me with any help/info that you may have.

    The warning light comes on and then the traction control goes off and the cruise control will disengage all at once. There is also no trailer brake assist. This has been verified by a dealer in Columbus, GA. It is constantly going off and on. The warning light and the warning bell are a constant distraction to the driver. The truck was bought and within 50K miles it started. No warning.

    ABS/TRACTION CONTROL light comes on and goes off at random times while driving. Sometimes when I hit a bump, other times just going down a smooth street or even sitting at a stop light or just sitting at idle in a parking lot. When the lights are on I do not have use of cruise control, traction Control or ABS. I had the code read. It shows c2200-49 ABS internal electronic failure C0020-01 ABS pump motor control - general electrical failure. This has been a problem for about 2 years, and started around 85k miles. Sometimes it happens 30-40x in a 30min drive, other times I'll go weeks with the system working properly, then It starts acting up again. I just recently heard they were investigating the 2018 models for this issue.
