Monthly complaint-burden ranking of US-market passenger vehicles by model year, from the official keyless NHTSA ODI complaints API (universe enumerated via vPIC). Per model-year: ODI-deduped complaint counts, crash/fire/injury/death tallies folded into a documented severity model (3*crash + 5*fire + 2*injuries + 10*deaths), a top-level NHTSA component taxonomy (VISIBILITY/WIPER -> VISIBILITY) with the dominant component and its share, year-over-year complaint change vs the prior model year, and a 0-100 complaint-burden composite (50% min-max(log1p(complaints)) + 50% min-max(severity rate)) ranked with deterministic tie-breaks. Vehicles with fewer than 5 complaints are excluded (noise gate; also screens out model keys the complaints index cannot resolve, e.g. dashed F-series keys). VINs and free-text summaries are never stored. The score is a complaint burden signal, not a defect rate: complaints are self-reported and counts are not normalized by sales volume. Primary key: (model_year, make_slug, model_slug). Cadence: monthly. Caveats: complaint counts tick as new complaints are filed, so same-month re-runs may differ slightly.

Column	Type	Description
model_year	integer	Vehicle model year. (unit: year)
make	string	Vehicle make, vPIC canonical name.
make_slug	string	URL-safe slug of the make.
model	string	Vehicle model, vPIC canonical name.
model_slug	string	URL-safe slug of the model.
vehicle_label	string	Human-readable 'YEAR Make Model' label.
nhtsa_url	string	Exact NHTSA complaints API query behind this row. (unit: URL)
complaint_count	integer	ODI-deduped complaints against this model year. (unit: count)
crash_count	integer	Complaints reporting a crash. (unit: count)
fire_count	integer	Complaints reporting a fire. (unit: count)
injury_total	integer	Total injuries reported. (unit: count)
death_total	integer	Total deaths reported. (unit: count)
severity_raw	float	Weighted severity: 3crash+5fire+2injuries+10deaths. (unit: score)
severity_rate	float	severity_raw per complaint. (unit: score)
severity_score	float	0-100 min-max normalized severity_rate. (unit: 0-100)
top_component	string	Most-complained top-level NHTSA component category.
top_component_share_pct	float	Share of complaints mentioning the top component. (unit: percent)
n_distinct_components	integer	Distinct top-level component categories. (unit: count)
complaints_yoy_pct	float	YoY complaint change vs prior model year of same make+model; null when the prior year is absent. (unit: percent)
burden_score	float	0-100 burden composite: 50% min-max(log1p(complaints)) + 50% severity_score. Burden, not a defect rate. (unit: 0-100)
burden_rank	integer	Deterministic rank: burden_score desc, then complaint_count desc, make_slug, model_slug, model_year desc. (unit: rank)
fetched_at	string	Trailing complete UTC day of the sweep. (unit: date)
row_hash	string	Deterministic 16-hex row hash.
