ATLANTA (AP) — Parents of a Georgia teenager who suffered a severe brain injury in a 2009 car crash say General Motors knew of a defect in her car but took steps to conceal it.

In a federal lawsuit filed Friday in U.S. District Court, Alexina and William Van Pelt of Evans say a defective key system in their daughter Haley’s 2003 Saturn Ion caused the key to move from the “run” to “accessory/off” position, shutting the engine off and causing her to lose control and smash into a tree.
