McQueen was married to Stacey Toten from 1987 to 1990. Together they had one son, Steven R. McQueen. Chad is also the stepbrother of producer and screenwriter Josh Evans (through his father's marriage to Ali MacGraw).
With his current girlfriend, Jeanie Galbraith, he has two children, Chase (born in 1995) and Madison (born in 1997).
McQueen has worked as a film actor for some time, appearing in The Karate Kid and many other roles. He has also worked as a producer.
McQueen's racing career began early as he piloted a Porsche 917 from his fathers lap while shooting the film, Le Mans. He teamed with Belgian racing legend, Jacky Ickx and his daughter Vanina piloting a trio of Porsche 959s restored by Porsche Motorsports for the 2004 Goodwood event.
McQueen has competed in several types of racing from Motocross to the Baja 1000. In 2004, he qualified for the SCCA Runoffs, winning multiple events. Racing for Westernesse Racing, he finished 4th.
In January 2006, he was seriously injured (suffered a broken lower left leg, as well as a pair of fractures to his vertebrae and multiple rib fractures) in an accident at the Daytona International Speedway while practicing for the Rolex 24 Hours of Daytona Sports Car race. McQueen now says that his driving days are over. He returned to Daytona during the 2007 Rolex 24 Hours of Daytona race to thank the medics and track workers who, he says, saved his life.
In November 2007, he returned to the Daytona International Speedway and got behind the wheel of the Brumos 1975 Ecurie Escargot RSR driving it in the exhibitions at the Rennsport Reunion III.
