Known issues on the 2004 Forenza. Five recalls are on federal record: a recall for the dual-stage driver air bag deploying in an improper sequence; a recall for a brake light switch that could go out of adjustment and leave the brake lights on continuously; a recall for a melted wiring-harness splice pack that could disable the low beams or daytime running lights; a recall for poor terminal contact that could overheat and melt the headlamp power splice pack, causing loss of low or high beams; plus one further campaign covering exterior lighting. NHTSA also logs 63 owner complaints, most often about exterior lighting and the electrical system. The manual's lighting circuit diagrams, component locations and replacement steps support checking whether that work was done.
