1989 Ford Mustang

The federal year-by-year record provided does not include 1989 itself, so the 1990 cohort—114 complaints, 5 recalls, 3 investigations, and 37 TSBs—serves as the closest baseline for placing the target year in context. Across the recorded range, complaints and recalls climb sharply from the early years (78–132 complaints, 5–7 recalls in 1990–1993) into a mid-decade peak of 701 complaints and 16 recalls in 1995, then oscillate and gradually decline toward 2026, meaning 1989 sits at the low-incident, pre-spike end of the arc. The 1989-specific data shows a clear concentration in the Electrical System category with 46 complaints, followed by Seat Belts (17), Vehicle Speed Control (7), and Structure (7), alongside 35 fire-related complaints and 3 crash-related filings—an unusually high fire count relative to the crash count for a vehicle of this vintage. The JSON does not specify a root cause for these electrical or fire complaints, so attributing them to a particular failure mode would be speculation, but the dominance of electrical complaints is the single most actionable flag. On balance, 1989 is one of the quieter years in the generation's federal record, but a pre-purchase inspection should prioritize the wiring harness, seat-belt retractors, and any evidence of under-dash thermal damage before committing.
