DETROIT — General Motors Co. said Monday it is recalling 1.5 million vehicles worldwide because the electronic power-steering assist can suddenly stop working, making them harder to steer.

GM said it expects recall-related costs to total $750 million in the first quarter, including $300 million for an earlier ignition switch recall that has prompted a congressional inquiry. Included in the new recall are:

- Chevrolet Malibu from the 2004-2005 model years, plus some 2006, 2008, and 2009 model-year cars; Malibu Maxx from the 2004-2005 model years, plus some 2006 model-year cars.

- Chevrolet HHR from the 2009-2010 model years (non-turbocharged only).


- Some Chevrolet Cobalts from the 2010 model year.

- Some Saturn Auras from the 2008-2009 model years.

- Saturn Ion from the 2004-2007 model years.

- Pontiac G6 from the 2005 model year, plus some cars from the 2006, 2008, and 2009 model years.

- Service parts installed into certain vehicles before May 31, 2010, under a previous recall.
