Summary Verdict

The 2012 Lincoln Mark LT presents a generally reliable platform, particularly its powertrain, which benefits from Ford’s extensive truck engineering. However, common issues tend to emerge in specific areas. The 5.4L V8 engine can experience camshaft phaser noise and spark plug blowouts, requiring attention. The 4R75E transmission, while robust, can develop torque converter problems or overheat if not properly maintained. Suspension components like ball joints are also noted for wear. Electrical gremlins, such as instrument cluster issues and window regulators, are not uncommon. Exterior and interior components, while less critical, can also present minor annoyances like tailgate latch or seat heater failures. Overall, the Mark LT is a capable vehicle, but owners should be aware of these potential repair points and factor them into long-term ownership costs.
