There are 1 owner-reported brakes complaints for the 2016 Ram ProMasterin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Parking brake won't release when temperatures are at freezing or below. Consensus opinion on the internet is that water is getting into the cable + cable housing line and freezing, which causes the cable to stick inside the housing. Thus, when releasing the parking brake, the cable doesn't move and the pads are still pressing against the drums.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
