The 2023 Nissan Z has 4 recalls, all centered on the same pedestrian safety system: a pop-up engine hood that may fail to activate in a frontal crash, leaving a pedestrian without a critical layer of protection.
Two separate defects can prevent the pop-up hood from working as intended. In one, the wiring connectors for the right-side pedestrian detection sensors may be reversed in the front bumper harness, meaning the sensors cannot properly signal the hood to raise. In the other, the fasteners securing the left-side front bumper reinforcement clip may not be tightened properly and can loosen over time, which also prevents the hood from lifting. The pop-up hood is designed to create a cushioning gap between the hood's rear edge and the hard components beneath it when the car strikes a pedestrian, reducing the severity of head impact. When either defect is present, the hood stays flat and that buffer is lost.
