The memorial has had some unforeseen maintenance issues. In 1984, cracks were detected in the granite and, as a result, two of the panels were temporarily removed in 1986 for study. More cracks were later discovered in 2010. There are a number of hypotheses about the cause of the cracks, the most common being due to thermal cycling. In 1990, the Vietnam Veterans Memorial Fund purchased several blank panels to use in case any were ever damaged; these were placed into storage at Quantico Marine Base. Two of the blank panels were shattered by the 2011 Virginia earthquake.
