Known issues on the 1986 S15 Jimmy. Three recalls are on the federal record for this year. One concerns replacement lamps built without the amber side reflectors federal rules require. Another involves certification labels printed with tire and wheel information that may not match the vehicle. The third covers a push-pull headlight switch whose contacts can become intermittent, so the headlights flicker or go out without warning. Three owner complaints are logged, one each on steering, the fuel system and seat belts, all systems this manual documents with their own procedures and specifications.
