Sheriff's spokesman Steve Whitmore says the 61-year-old singer was arrested Friday in South Los Angeles after the car she was riding in was pulled over for a mechanical malfunction.
Deputies say she was released after posting $10,000 bail.
In a statement issued through her manager Robert Watson, Pointer thanked the public for their support and prayers.
Watson declined comment on the arrest.
The Pointer Sisters grew up singing in church. Patricia and June formed a duo and were singing in clubs when Anita and Ruth joined them.
The sisters released their first album in 1973 and won a Grammy in 1974. Bonnie left in 1977 for a solo career.
She is due in court on Jan. 17.
