The vehicles are mostly cars manufactured between 1997 and 2014 and are being recalled for ignition switch defects.
Among the recalled vehicles, the US car giant says it is aware of seven crashes, eight injuries and three fatalities.
GM said it would take a charge of $1.2 billion for recall-related repairs – up from the $700 million it had previously estimated.
However, GM said there was “no conclusive evidence” that the switch defects directly caused the crashes.
GM CEO Mary Barra said in a statement: “We undertook what I believe is the most comprehensive safety review in the history of our company because nothing is more important than the safety of our customers.”
“Our customers deserve more than we delivered in these vehicles.”
The new recalls come on the same day GM announced details of a compensation fund for recall victims.
Kenneth Feinberg – the man GM appointed to deal with compensating those affected by the recalls – has said that the carmaker will not put a cap on the amount it will pay to victims.
Separately, Orange County, California, revealed it had filed a civil lawsuit against GM last Friday.
The Orange County District Attorney alleged that GM “endangered the public through deception regarding vehicle safety and reliability and gained advantage over its competitors by engaging in unfair business practices”.
