CNN -- T
he new General Motors (GM) CEO Mary Barra is about to face congress to testify on April 1 on vehicles with an ignition flaw that has been linked to the deaths of 13 people.
GM is expanding its ignition switch recall to nearly an additional million cars from model years including 2008-2011 because the same faulty switches that were found in older cars may have found their way into newer cars during repairs.
GM told ABC news that they are no known deaths linked to this recall of newer vehicles, but they're not taking chances.
"We have work to do to improve our process and we are dedicated to doing that," Barra said.
The expanded recall is coming just days after Barra issued an apology to customers, pledging to conduct her own investigation into why General Motors took more than a decade to recall 1.6 million cars linked to at least a dozen deaths.
"I can commit to you, we will put all those processes and learnings in place to make sure this never happens again," she said.
In other GM news, the company ordered dealers to stop all sales of 2013 and 2014 Chevy Cruzes with 1.4 turbo engines, but declined to say more than it's not an ignition issue.
Congress and federal government have launched investigations into GM's handling of the ignition recall and class action lawsuits are mounting as GM faces claims that the company misled some grieving family members about the potentially deadly flaw.
