After driving on the snow and ice, I had a check engine light that came on. The next day I went to Lake Ridge Automotive and they promptly checked out the problem which apparently was something minor causing it and the check engine light coming on problem went away. In addition, there was no charge for what they did to correct the problem. It is most strongly recommended that all Northern Virginians consider taking their car(s) to Lake Ridge Automotive for their maintenance/repair needs.
