The 2007 Lincoln MKZ has 4 recalls, the most serious being a Takata airbag defect affecting both the driver and passenger frontal inflators, which can rupture and send metal fragments into the cabin, causing serious injury or death.
Both the driver-side and passenger-side airbag inflators are subject to this defect. The driver-side inflator can fail on any affected vehicle, while the passenger-side inflator concern is specifically tied to vehicles that were sold or registered in high-humidity regions such as Florida, Texas, Hawaii, and several other warm coastal states and territories. In both cases, the inflator can rupture rather than deploy cleanly, throwing sharp metal pieces toward the driver and front passenger. These are among the most serious defects seen in recalls across many makes and models.
On the brake side, the anti-lock brake system's hydraulic control unit contains valves that can react poorly with certain brake fluid formulations and fail to close fully. When that happens, the brake pedal travels further than normal before the brakes engage, meaning the car takes longer to stop than the driver expects, raising the risk of a collision.
