Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1966 Mustang.
The 1966 Ford Mustang is a low-event entry in the model's long-term reliability record, with just 5 owner complaints, one recall, and tires standing out as the top reported concern. That profile sits near the quiet end of the 1990–2026 complaint history, which ranges from a high of 868 complaints in 2005 to only 4 in 2026. For researchers, this makes the 1966 model a comparatively stable reference point with minimal owner-reported activity.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The federal record you provided covers 1990‑2026, a period in which complaints per year ranged from a low of 48 in 2022 to a high of 868 in 2005. Recalls fluctuated modestly, generally staying between 5 and 13 per year, with no single decade showing a pronounced escalation. Investigations were rare, occurring in only a handful of years, while total safety‑related breakdowns (TSBs) peaked in 1995 at 160 and dropped to single digits by 2026. Since the record does not include the 1966 Mustang, no direct comparison can be made; the data simply does not specify any complaint or recall trend for that model year. Consequently, you cannot rely on this federal snapshot to assess the 1966 Mustang’s reliability, and you should seek dedicated vintage‑Mustang service histories or specialized collector reports before deciding to purchase.
