Fifteen General Motors executives have been fired over the long-running scandal over faulty car ignitions.
CEO Mary Barra has released a report by former US attorney Anton Valukas, who was hired for an internal review of GM’s failures. The ignition defect has killed at least 13 people, Time notes.
GM was fined $US 35 million earlier in the year over its failure to report the ignition problems.
"The Cobalt saga was riddled with failure," said Barra, according to AFP.
"We misdiagnosed the problem from the very beginning ... We have to own this problem."
Barra said the report made no findings of a deliberate cover-up, but rather, a pattern of management deficiencies and misjudgments.”
"Some were removed because of what we consider misconduct or incompetence," she said.
"Others have been relieved because they simply didn't do enough: They didn’t take responsibility; didn’t act with any sense of urgency.
