General Motors Co. Chief Executive Fritz Henderson stepped down today, signaling continued turmoil over turnaround efforts at the troubled automaker.
Board chairman Edward Whitacre Jr. will temporarily take over the CEO spot until a permanent replacement is found, GM said.
"We all agreed more changes were needed," Whitacre said to reporters in a press conference in Detroit.
Henderson, a longtime GM veteran, was named to the top executive job in March, following the removal of his predecessor, Rick Wagoner, at the hands of the Obama administration. Soon thereafter, he took GM into bankruptcy and since then has overseen its emergence and push to reduce costs, workforce and vehicle brands.
Henderson had been scheduled to give the keynote speech at the Los Angeles Auto Show on Wednesday morning. A GM spokesman said that Bob Lutz, the automaker's head of marketing, would instead make that presentation.
Whitacre, who was named chairman in June, with backing from the White House, has repeatedly voiced support for Henderson. But the past few months have been rocky at the automaker.
