Engine-Family Complaint Density
Curated problematic engine families (documented defect patterns — class actions, NHTSA investigations, or 100+ fleet complaints), with total NHTSA complaints, recalls, and complaints normalized per model-year entry. Density lets you compare families of different production volumes.

Source & methodology
Families are the editorial set powering /engines/. For each family we sum complaints/recalls/harm flags across every matching (year, make, model) in the DB. "complaints_per_modelyear" = total complaints ÷ model-year entries present. Complaints are unverified consumer reports.
