nhtsa: stage 01 Data

Inputs. NHTSA ODI flat files fetched 2026-10-10 from static.nhtsa.gov/odi/ffdd: FLAT_CMPL.zip (complaints since 1995, 2,255,013 rows), FLAT_RCL_PRE_2010.zip and FLAT_RCL_POST_2010.zip (recalls since 1966, 327,565 rows), field lists CMPL.txt and RCL.txt. Kept unaltered under raw/.

Output. nhtsa on line universal: 2,449,969 events on 99,014 streams, 1979-10-12 to 2026-10-08. Stream is the vehicle, MAKE | MODEL | MODEL YEAR; 91% of vehicle complaints share their key with some vehicle recall.

Decisions (owner-confirmed 2026-10-10).

ts is DATEA, the date the record was added to ODI's file, on both tables. Since 2005 it

equals the complaint's received date in 99%+ of rows; recalls land 0–3 days after the Part 573 filing. Before 2005 complaints were keyed in with lags of weeks to months. Received, incident, filing and owner-notification dates stay in raw/ only.

Verb: the component recoded by prefix into 23 families shared by both taxonomies (complaint

intake switched to consumer names around 2012, recalls kept engineering names); unmatched components are other (mostly UNKNOWN OR OTHER, child seats, interior lighting, trailer hitches). The full component string is the fact component; the model year is the fact model_year (9999 means unknown).

Recalls are distinct on campaign, vehicle and component: since 2020 the file lists a recall once

per part number (132,446 repeats rejected). 163 complaint rows rejected: 24 with no make/model/year, 139 with no component.

kind is complaint or recall. Facts: complaint severity, vehicle attributes and source

(cmpl_type); recall type, origin (influenced_by: MFR, ODI, OVSC), units affected, FMVSS. Narratives and personal fields (VIN, city, dealer, operator name) are not facts.

Drift. At ingest, 51 verb flags (27 spikes, 24 dropouts), the large ones real-world episodes: Firestone tires 2000, Toyota acceleration 2010, forward-collision braking 2022. At the 2021-06 split, verb-mix TVD 0.21: driver-assist families are nearly absent before it (forward_collision ×55, back_over ×32), air bags and tires halve.

Open questions and caveats.

NHTSA's May 2021 file rebuild says make, model and component names "may have changed over

time"; complaints received before then may carry components recoded after the fact, possibly toward a later recall. Test anchors are kept after 2021-06-01; training-era labels and the component of training anchors carry this caveat. Old complaints keep old-era names, so there was no wholesale rename.

A recall usually spans several model years (61% of campaigns since 2010); the universal line

cannot link sibling streams.

Tires, equipment and child-seat products are in the spine as their own streams; targets filter

them with prod_type and rcltypecd.

Next stage. Author the Atlas with its cutoff at 2021-06-01, so vocabularies and fact kinds are read on training events only.

# NHTSA ODI complaints and recalls, one spine keyed by vehicle (make | model | model year).
# Capture: static.nhtsa.gov/odi/ffdd/{cmpl,rcl}, fetched 2026-10-10 (pipeline/ingest/data/nhtsa/captures/2026-10-10).
# Verb: the component recoded into 23 families across both taxonomies (complaint intake renamed its
# components around 2012; recalls kept theirs); unmatched components are `other`. The full component
# string rides along as the fact `component`. Recalls are one row per part number since 2020: distinct
# on campaign, vehicle and component.
# ts is DATEA on both tables, the date the record was added to ODI's file: the visibility time.
# Complaint LDATE (received) and FAILDATE (incident), recall RCDATE (Part 573 received) and ODATE
# (owners notified) are claimed dates and stay in raw/ only.
# Free text (CDESCR, recall summaries) and personal fields (VIN, city, dealer, operator name) stay in raw/ only.
