Evaluating the 2009 Lincoln MKS reliability requires looking at a vehicle that represented a significant shift for the Lincoln brand. As a direct competitor to German luxury sedans, the MKS was built on the Ford D3 platform, sharing its core structure with the Ford Taurus and Police Interceptor models. This shared engineering foundation means the MKS benefits from a platform that was well-regarded for its rigidity and crash safety, but it also inherits specific mechanical traits that define its long-term ownership experience.
Mechanical Components and Drivetrain
The standard powertrain for the 2009 model year was a 3.7-liter V6, producing 263 horsepower and pairing with a six-speed automatic transmission. This combination provided adequate power for daily driving and highway merging, delivering a balance between performance and fuel efficiency. The AWD system, available on select trims, utilized a clutch-based transfer case that generally proved robust, though drivers in regions with heavy snowfall appreciated the traction it provided during winter months.
Engine: 3.7L Cyclone V6 (Duratec 37)
Transmission: 6-speed 6F automatic
Drivetrain: Rear-wheel drive standard, optional all-wheel drive
Common Engine Concerns
While the 3.7L engine is generally considered reliable, specific issues can arise if maintenance is neglected. The most notable concern involves the potential for carbon buildup on the intake valves, a common trait in direct-injection Ford engines of this era. This buildup can lead to a rough idle, misfires, or decreased fuel economy over time. Regular oil changes using the correct viscosity and adhering to the manufacturer's service schedule are critical preventative measures.
Interior Comfort and Technology
The 2009 MKS is remembered for its serene and spacious cabin, which emphasized comfort above all else. The front seats offered substantial support and were adjustable in multiple dimensions, allowing drivers to find an ergonomic position for long trips. The available heated front and rear seats were a highlight, providing consistent warmth that enhanced the luxury feel during colder weather.
The infotainment system, centered around a large LCD screen, featured a dual-screen DVD option for rear passengers, a rarity at the time. However, the complexity of the touch-sensitive climate controls and audio dials located on the center console received mixed reviews. Some owners found the interface unintuitive, leading to accidental adjustments while driving, which underscores the importance of familiarizing oneself with the layout during the ownership period.
Exterior Design and Build Quality
Designed by J Mays, the exterior of the 2009 MKS boasted a bold, angular design that set it apart from the more conservative Town Car. The use of high-strength steel provided a solid foundation, contributing to the vehicle's excellent crash test ratings from the IIHS. The panoramic moonroof, while a beautiful feature, requires attention to the drainage channels to prevent water from pooling and potentially leaking into the headliner.
Reliability Statistics and Owner Feedback
Looking at aggregated reliability data from sources like Consumer Reports and J.D. Power, the 2009 Lincoln MKS generally falls into the average to above-average category for luxury sedans of its time. Major mechanical failures are not widespread, but like any aging vehicle, specific components are prone to wear. The auxiliary drive belt (serpentine belt) routing is complex, and accessing it for replacement can be labor-intensive, making it a higher-cost repair when the belt eventually fails.
