Communications chief Selim Bingol and human resources head Melissa Howell are leaving the company to pursue other interests, the company said today in a statement.
John Quattrone, who currently is executive director of human resources, will replace Howell, but GM has not yet named a replacement for Bingol, the statement said. The changes are effective immediately.
GM is in the midst of a crisis over safety of some of its older-model vehicles, including 2.6 million small cars worldwide that have been recalled to replace faulty ignition switches. GM says at least 13 deaths have been linked to the switch problem. Family members of those killed say the death toll is much higher.
But GM spokesman Greg Martin said the moves are not linked to the recalls. He attributed them to CEO Mary Barra, who took over in February, making her own hires in key positions. "The changes are part of what any company expects during periods of transition, and Mary is building her own team," Martin said.

GM credits Bingol with guiding the communications for the company's successful initial public stock offering in November of 2010, after the company emerged from bankruptcy protection.
Quattrone started working at GM in 1975 at the Fisher Body plant in Syracuse, New York. He has held several posts in HR and labor relations for the company since then. Before being promoted, he was the vice president for human resources for GM's engine and transmission operations.
Also today, Barra promised employees on a company blog that the company's senior leadership will react quickly to tips from employees about safety problems.
