GM's massive ignition switch recall, which initially featured 1.6M cars in February, has been expanded to include certain 2008-2011 models of the Chevy Cobalt and HHR, Pontiac G5 and Solstice, and Saturn Sky.
The recall originally featured older models of the aforementioned cars, as well as the Saturn Ion. Though GM says the newer models feature a redesigned ignition switch, some may have been repaired with potentially faulty older replacement parts.
Regulators and class-action lawyers have already sprung into action over GM's faulty ignition switches, which have been linked to a dozen deaths. CEO Mary Barra is set to testify before Congress on Tuesday.
