GM's recall list now totals more than 2.5 million cars for a possible faulty ignition switch. The recall started in February with about 1.62 million.
Friday, GM Chief Executive Mary Barra said the company isn't taking any chances with safety.
Drivers of newly recalled vehicles say they are taking a chance with their life every time they're in the driver seat.
"People's lives are in danger and they have been killed in these vehicles," said Todd Jones.
Jones drives a Chevy HHR; his car and more than 2.5 million others are being recalled for a possible ignition switch problem that could cause the car to shut off without warning, disabling safety features like air bags.
"I got a notice in the mail about three months after I had seen it on TV," said Jones.
GM's addition of more than 800,000 cars is concerning Jones because the company has already told him there will be a wait.
"They were short on parts and it would be a while to before they get to it," said Jones.
In an online statement GM Chief Executive Mary Barra addresses Jones' concern.
"We have worked with our supplier as soon as possible and these are parts that have gone through our complete validation process," said Barra.
Barra says GM should have parts for all vehicles recalled no later than October. Meanwhile, Jones says his family will continue to use their recalled HHR.
"I have no choice. I canâ??t afford to go out and get another vehicle," said Jones.
GM says it's not aware of any driving deaths connected to the ignition defect in the 2008-2011 models now recalled; however, a dozen deaths are being blamed on older models.
All model years of the Chevrolet Cobalt, Chevrolet HHR, Pontiac G5, Pontiac Solstice, Saturn Ion and Saturn Sky.
