The crimp contacts on most of these connectors is made from tin plated brass. They are typically good for a few dozen cycles.
Dielectric grease is actually an insulator. It helps only to prevent corrosion due to moisture.
I would try to bend the pins slightly to make more solid contact. Also make sure none of the wires have pulled out of their crimp contacts. If you break a pin, you can find them on Digikey and Mouser. Look for ".070 MULTILOCK" This is used on most the larger connectors on Subaru.
