Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1991 Mercury Capri marks the debut year of this generation, and the federal data reflects typical first-year challenges, with 40 complaints—significantly higher than the 14 in 1992 and the single-digit figures in subsequent years. Recalls and investigations also peaked in 1991 (2 recalls, 1 investigation), suggesting early production issues, while later years saw only one recall annually with no further investigations. Complaint trends reveal recurring concerns in visibility, powertrain, electrical systems, and airbags, though the data doesn’t specify root causes. Crash and fire complaints (4 and 2, respectively) are notable but not disproportionately high for a first-year model. The sharp decline in complaints after 1991 implies that many issues were addressed in later production or through TSBs, which remained consistent (21 in 1991 and 1992). **Takeaway:** While the 1991 Capri isn’t inherently unreliable, its higher complaint and recall volume makes a later model year (1992 or newer) a more predictable choice—unless thorough service records and pre-purchase inspection confirm its issues were resolved.
