The 1991 Mazda Navajo has 5 recalls, the most serious being a fire risk from a heat shield that can contact and puncture the plastic fuel tank, allowing fuel or vapors to escape and ignite.
The automatic transmission carries its own safety concern: the park pawl may not fully engage when the shifter is moved to Park, meaning the vehicle can roll even though the driver believes it is secured. On the brake side, the studs connecting the brake master cylinder to the power brake booster can develop cracks over time, and if one or both studs fracture, braking performance can be compromised. Two structural issues round out the list: the rear bumper can crack from fatigue if the vehicle has been used to tow a trailer with a bumper-mounted hitch, and it may separate from the vehicle under load. On vehicles with a factory sunroof, the glass panel can separate from the roof while the vehicle is moving due to improper hinge engagement, which can startle the driver and raise the risk of a crash.
