A mechanical defect in the switch is at the heart of the other recall. GM is in the midst of a companywide safety review, and has now issued 44 recalls this year covering more than 20 million vehicles — nearly 18 million the U.S. The latest recall is likely to spark more questions about GM's commitment to safety when CEO Mary Barra testifies for the second time before a House panel investigating why it took GM 11 years to recall the small cars. Barra endured some harsh questions in April, but refused to answer most pending the release of an internal investigation. GM released those results on June 5, blaming a dysfunctional corporate structure and poor decisions by some employees for the crisis. The company also announced plans to establish a fund to compensate the families of those who died, plus those injured in more than 50 crashes.
