GM adds 970,700 newer cars to switch recall

General Motors late Friday expanded its ignition switch recall to cover 824,000 newer models of the same cars in the U.S., and 970,700 worldwide.

GM says it now will replace the ignition switch in all model years of its Chevrolet Cobalt, HHR, Pontiac G5, Solstice and Saturn Ion and Sky. Until now the recall covered only cars through the 2007 model year.
