The 1998 Mazda B Series has 4 recalls, the most serious being three separate fire and safety risks: a speed control switch that can overheat and catch fire under the hood, a fuel line that can contact the exhaust manifold and leak fuel near an ignition source, and a stuck throttle that can result from the speed control cable interfering with the servo pulley.
The throttle issue and the overheating switch are both tied to the speed control system: if the cable binds against the pulley, the throttle may not return to idle when cruise control is switched off, leaving the driver unable to slow the vehicle normally. The fuel line concern is separate, where a flexible section of the chassis-mounted line runs close enough to the exhaust manifold to wear through and release fuel. The fourth recall is a compliance matter involving windshield glass that was produced without a required certification mark, though the glass itself meets all applicable safety standards.
