Summary

The 2011 Lincoln MKZ, while offering a comfortable driving experience, does have some potential issues to watch out for. The water pump failures on the 3.5L and 3.7L engines are particularly concerning due to the potential for severe engine damage, and repairs can be costly. Transmission issues with the 6F35, such as harsh shifting and torque converter shudder, are also common. Electrical gremlins with the Sync system and power accessories can be frustrating to deal with. Overall, prospective buyers should be aware of these potential issues and have the vehicle thoroughly inspected before purchase, paying particular attention to the cooling system, transmission behavior, and electrical systems. While some issues are relatively inexpensive to fix, others, like engine and transmission repairs, can be quite costly.
