The 2014 Mazda3 has 5 recalls, the most serious being a fuel tank defect where a weld can break and allow fuel to leak, raising the risk of fire if a source of ignition is nearby.
The parking brake has a separate concern: water can get into the brake caliper and corrode the parking brake actuator shaft, causing it to bind so the parking brake may not fully engage or release. There is also a rearview camera issue where a faulty connector causes the image to flicker or show distortion while backing up, reducing rear visibility; this recall only affects hatchback models.
