On October 4, 2013, Mars was involved in a car accident on U.S. Route 50 in Aldie, near her home in The Plains in Northern Virginia. Her vehicle crossed the highway center line and struck a Chrysler minivan carrying six passengers. One person died at the scene, while another was pregnant and subsequently miscarried. Mars was charged with reckless driving, and told a witness after the accident that she had fallen asleep at the wheel. Mars subsequently pleaded guilty to the misdemeanor charge of reckless driving, with tests having revealed no drugs, alcohol or medications in her system that could have caused a blackout.
