Known issues on the 1987 S15 Jimmy. Three recalls are on the federal record. Two involve replacement lamps lacking the amber side reflectors federal lighting rules require. The third is a steering matter: inner tie rod nuts at the relay rod that were not properly torqued or crimped, which can loosen and allow the tie rod to disengage, taking steering control with it. Four owner complaints are logged, with engine and engine cooling accounting for two and the electrical system and steering one each. Steering linkage torque values, cooling procedures and lighting diagnostics all appear here.
