One of the main reasons for a trunk leak on any car, like the Lincoln MKZ, is when the weather stripping around the trunk fails or degrades. Another possible reason could be a blocked or damaged drainage tube, but this alone won't cause water to get into the trunk; there also needs to be a gap in the weather seal for water to seep in. Start by checking the seal around the trunk's perimeter for any signs of wear, damage, or deterioration. If there's just one spot where it's broken, you may be able to fix it using some silicone glue or a similar product. However, if the damage is extensive, you might need to replace the whole seal, which usually costs around $60, so it's not too pricey.

Typically, if a Lincoln MKZ's trunk is leaking water, it's likely due to a faulty or loose weather stripping that allows water to seep through the damaged section.

The trunk may be leaking due to various issues. First, inspect the top of the lid to ensure there is a black rubber gasket without any cuts or splices. The gasket should be hand-pressed on and there shouldn't be any objects obstructing the lid from fully closing. If the trunk is power-operated, open it and remove any obstructions preventing the lid from closing securely. Test the power trunk's full operation, listening for the motor that secures the lid in place as it closes. If the lid was forcefully slammed down, you may need to resynchronize it with the motor by using the power trunk switches several times. It's important to verify if the vehicle has been rear-ended in an accident and not repaired properly. A paper test can be conducted by placing paper between the gasket and trunk lip, then closing the trunk and trying to pull out the paper, identifying any areas where the gasket doesn't seal correctly. Additionally, you can pour water over the trunk seam and inspect for any signs of water leakage after opening the trunk.

The trunk seal is in perfect condition. However, when the trunk is closed, I observed that it moves slightly from side to side as the motor pulls it shut. I attempted to resynchronize it but was unsuccessful.
