No.
First, note that the third paragraph of the CNN article indicates that the claim is specific to presidential elections, not midterm or off-year, which typically have even lower turnout. This answer will thus focus solely on presidential elections.
Also note that "voter turnout" (as defined by the CNN article and anyone else who wants the numbers to be comparable across increases in population) is the percentage of voting-age citizens who cast a ballot, not the absolute number of votes cast.
Taking the above into account, then according to the FEC, the lowest voter turnout rate after 1996 was in 2000, with 51.21%. 2016's turnout rate of 55.67% exceeds the turnouts in both 2000 and 2012.
