Ford spokesman Oscar Suris has confirmed to The Associated Press (AP) that Ford Phil Martens, the company’s vice president for product creation, and Matt DeMars, vice president for vehicle operations, plan to leave.

Suris reportedly said Bill Ford, the automaker’s chairman and chief executive officer, and Mark Fields, Ford’s president for the Americas, had assessed the company’s management team in North and South America.

“We expect they will review certain leadership changes with our board in the very near future,” Suris told AP in a prepared statement. “We would not be surprised if some people elect to leave Ford Motor Co. in the meantime. If they choose to do that, that is of course their decision.”

Other reports said that Fields and Marten had clashed earlier in their careers, when both were at Mazda.
