The 2009 Lincoln MKZ has 6 recalls, the most serious being a Takata airbag defect affecting both the driver and passenger frontal inflators, which can explode 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 inflators can degrade over time, particularly in high-humidity and high-heat environments, and rupture violently when the airbag deploys in a crash rather than inflating normally. Because multiple recall filings cover the same underlying Takata inflator problem from different angles, owners should confirm with their dealer or by VIN lookup whether both inflators on their specific vehicle have been remedied, as prior repair attempts for one side may not have addressed the other.
On the braking side, the anti-lock brake system's hydraulic control unit contains valves that can react with certain brake fluid formulations and fail to close fully. When this happens, the brake pedal travels farther than normal before the vehicle slows, which increases stopping distance and the risk of a crash. This issue affects the hydraulic control unit, not the brake pads or lines, so the pedal may feel soft or unresponsive before the problem becomes apparent during hard braking.
