1973 Vehicle Safety Complaints

The 1973 model year cohort has accumulated 30 NHTSA consumer safety complaints across 22 nameplates from 13 manufacturers — a cross-section of everything the Office of Defects Investigation has filed for vehicles whose model year stamp reads 1973. Severity indicators inside this cohort include 2 crash reports, 3 fire incidents, and 0 reported fatalities, all owner-submitted through NHTSA's public complaint portal.

Inside the 1973 cohort, the MERCURY COUGAR leads the complaint count with 3 filings, followed by the CADILLAC ELDORADO and the GMC GMC. On the component side, the most frequently cited category for the 1973 year class is tires:tread/belt (6 complaints), ahead of tires and fuel system, gasoline:storage:tank assembly. Comparing a single model year against adjacent years is one of the cleanest ways to detect platform-level supplier changes: a sharp year-over-year jump in a specific component, concentrated on a handful of nameplates sharing an architecture, is the classic early-warning signature that regulators and insurance actuaries flag.

Remember that complaint volume is not a reliability ranking. Newer model years have spent less time on the road and therefore accumulate fewer filings, while older model years may be artificially quiet because few examples are still registered. NHTSA's Early Warning Reporting system weights complaints per registered vehicle, not just raw counts, when deciding whether to open a Preliminary Evaluation on a 1973 cohort. Drill into any model in the table below to see its component-level breakdown, safety rating, and recall history — and compare against the 1972 and 1974 cohorts to spot year-over-year discontinuities that point to real defect patterns rather than statistical noise.
