The 2008 Lincoln MKZ has 4 recalls, the most serious being a Takata airbag defect affecting both the driver and passenger sides, where the inflators can rupture and send metal fragments into the cabin, causing serious injury or death.
Both frontal airbag inflators are subject to this defect. On the driver's side, long-term exposure to heat and humidity causes the propellant inside the inflator to degrade, which can lead to an explosive rupture rather than a controlled deployment. The passenger-side inflator carries the same rupture risk and is the subject of two separate filings, one of which specifically targets vehicles registered in high-heat, high-humidity states and territories such as Florida, Texas, Hawaii, and Puerto Rico, where the environmental conditions accelerate the degradation. Prior repair attempts did not fully resolve the issue, which is why multiple filings exist for the passenger side. Together, these airbag concerns represent a significant hazard for all occupants.
On the braking 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 this happens, the brake pedal travels further than normal before the brakes engage, which means stopping distances stretch out unexpectedly and the risk of a crash increases.
