There are 2 owner-reported steering complaints for the 2018 Ram ProMasterin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
My power steering locked up and almost caused an accident. The dealer said they are having trouble with this component (corrosion in plug). I have a fleet of trucks, and I just had the same issue with a 2023 model which I also almost lost control of the vehicle. This is a defect or poor design that needs to be recalled before someone get seriously hurt.
