Known issues on the 1986 Fiero. For the 1986 Fiero, owners filed 25 complaints, and 15 of them fall under engine and engine cooling, with 4 on the parking brake; 5 complaints reported a fire and 2 an injury. The federal record holds 3 recalls. The parking brake campaign recalled certain 1986 Fiero cars with manual transmissions because the adjuster could fail to take up pad wear, letting a parked car roll on a grade; nonfunctioning adjusters were replaced. Another recalled certain four-cylinder 1986 Fiero cars over an engine compartment fire risk. Brake, engine and cooling procedures and specifications here address both concerns.
