Known issues on the 1989 S15 Jimmy. Three recalls sit on the federal record. Two cover replacement lamps missing the amber side reflectors federal rules require. The third is the more consequential one: engine cooling fan blades that fatigue and break apart, able to throw a fragment at someone working under an open hood. Eleven owner complaints are logged, with engine and engine cooling and the electrical system each accounting for two of the leading entries and exterior lighting for one. The cooling, charging and lighting sections carry the matching procedures, specifications, torque values and diagnostics.
