The 1994 Mazda B Series has 4 recalls, with two tied for most serious: ice forming in the throttle body can cause the engine to hold highway speed even after the driver lifts off the accelerator, and cracked front fuel hoses can leak fuel and start a fire.
The throttle issue develops after extended driving at highway speeds in extreme cold, where ice accumulates around the throttle plate and prevents it from closing when the accelerator pedal is released or cruise control is turned off, leaving the truck pulling forward under engine power with no response to the driver's foot. The fuel hose concern is separate: the flexible section of the front fuel lines can crack over time, allowing raw fuel to escape near engine heat and ignition sources. On the braking side, this recall only affects manual transmission models: yanking the parking brake on quickly can cause the self-adjusting pawl to skip over teeth in the ratchet mechanism, leaving the brake without full tension and potentially allowing the truck to roll on a slope. The final recall is a compliance issue involving the wheels, which were supplied without required rim markings, meaning the wheels lack information that tire shops and owners rely on when selecting compatible tires.

What can fail
During extended highway driving in extreme cold, ice can form in the throttle body. This may cause the throttle plate to stick in the cruising position even after you release the accelerator or turn off cruise control.
What the fix does
The air intake duct and valve assembly will be replaced with revised units that prevent ice formation.

At a glance
What can fail
When the parking brake is applied quickly, the self-adjustment pawl may skip teeth on the ratchet, preventing full parking brake tension and reducing braking effectiveness.
What the fix does
A lock-in wedge will be installed to lock the self-adjust mechanism and keep the pawl properly meshed with the ratchet.

At a glance
What can fail
The flexible part of the front fuel hoses may develop cracks. Cracked hoses can leak fuel, which could catch fire if exposed to an ignition source.
What the fix does
Technicians will inspect the front fuel lines and replace them if cracking is found.
