The 1991 Mazda MPV has 3 recalls, the most serious involving the ignition switch, where internal grease can become conductive, overheat, and start a fire.
The front seatbelt buckles carry a separate concern: the red plastic release buttons can crack and break, sending fragments into the buckle mechanism. If debris jams the assembly, the buckle may fail to latch securely or release at the wrong moment, leaving occupants without reliable belt protection in a crash. On the braking side, the rear brake shoe linings can change their friction characteristics as they wear, causing the brakes to grab harder than expected. This inconsistency can trigger the anti-lock brake system prematurely, which may produce sudden stops or unexpectedly longer stopping distances depending on conditions.
