DETROIT (AP) -- General Motors is recalling 3.16 million more automobiles in the U.S. because of ignition switch problems.

The company says it will change or replace the keys on the cars from the 2000 to 2014 model years.

GM says the switches can unexpectedly move out of the "run" position if the cars are jarred, such as by going over railroad tracks or a pothole. That can shut off the engines and disable power steering. The company says the use of a key with a hole, rather than a slotted key, addresses the issue.

The models involved in the recall announced today are Buick Lacrosse (model year 2005-2009), Chevrolet Impala (MY 2006-2014), Cadillac Deville (MY 2000-2005), Cadillac DTS (MY 2004-2011), Buick Lucerne (MY 2006-2011), Buick Regal LS & GS (MY 2004-2005), and Chevy Monte Carlo (MY 2006-2008).

The recall is part of a GM review of ignition switches after the company recalled 2.6 million older small cars earlier this year for a similar problem.

GM also is recalling 166,000 other automobiles for a series of problems.

And the company raised its expected second-quarter charge for recall expenses to $700 million, an increase from a previous estimate of $400 million.

On Friday, GM announced a Camaro recall that put its recalls for the year near a record 16.5 million vehicles.
