DETROIT -- Chrysler's new Italian management has once again shaken up the automaker's executive team, announcing the departure of two recently appointed brand CEOs and splitting the Dodge brand into two groups, one focusing on trucks and the other on cars, according to The Associated Press.

The moves, announced Monday, marked the second management shake-up since Fiat Group SpA CEO Sergio Marchionne took control of Chrysler on June 10 when it emerged from Chapter 11 bankruptcy protection.

Peter Fong, president and CEO of the Chrysler brand and the company's top sales executive, and Michael Accavitti, president and CEO of the Dodge brand, abruptly left the company, Fong for personal reasons and Accavitti to pursue other interests, Chrysler said in a statement.

Sales of Chrysler Group LLC vehicles, which consist of the Chrysler, Dodge and Jeep brands, are down 39 percent for the first nine months of the year. Chrysler also was caught unprepared for the government's Cash for Clunkers program and had too few small vehicles on dealer lots to benefit much from the rebates.
