1986 Ford Aerostar

The provided federal record begins in 1990, meaning the years immediately before and after 1986 are unavailable for direct comparison, though the 1986-specific data reveals 23 electrical system complaints, 18 engine and cooling complaints, 7 power train complaints, and 5 seat belt complaints. Notably, the 1986 model records 26 fire complaints and 3 crash complaints, a significant volume of fire incidents relative to its total complaint areas, though the data does not specify a root cause. Across the documented 1990-2000 generation arc, complaints peaked in 1993 at 471 before steadily declining to just 4 by 1998, while recalls remained relatively consistent (4-7 per year) through 1997. As a predecessor to this documented arc, the 1986 Aerostar lacks the later years' accumulated TSB coverage, which grew from 46 in 1990 to 107 in 1997, implying fewer documented manufacturer fixes were available for its early issues. Given the substantial number of fire and electrical complaints for 1986 and the absence of early-generation technical service bulletins in the record, this is a higher-risk model year that warrants a particularly rigorous inspection of the electrical and engine systems before buying.
