Upgraded a Magento installation to 2.1.3 and this issue still occurs.

Configured a variant (simple product) under a configurable product and added a special price that has already lapsed:

Special price still shows up in the front-end:

Hi,
the problem is that the from and to date won't be selected from the database. To fix this issue you need to edit the following file:
vendor/magento/module-configurable-product/Pricing/Price/LowestPriceOptionsProvider.php

change line 58:
from:
->addAttributeToSelect(['price', 'special_price'])
to:
->addAttributeToSelect(['price', 'special_price', 'special_from_date', 'special_to_date'])
