Consumer Description

My truck is a 2018 Ram 3500 with only 12,500 miles on it, and it is not driven in the winter. Recently it has been has intermittent activation of the ABS and traction lights. It has been on consistent for over a month now. I code scan showed C0020-01 ABS module general electrical failure. I search online and talking with the dealership revealed this is a fairly common issue on 2017 and 2018 trucks and the fix with either the HCU, ABS module or both. I see NHTSA has opened and investigation into the matter so I am just reporting mine as additional truck with issues. It has not been repaired yet. Thanks.
