This week, General Motors finds itself in the unenviable position of needing to explain itself to the US Congress. Problems with an ignition switch have led to a massive 4.8 million vehicles being recalled in the last month. More alarmingly, this faulty part has been linked to 13 motor vehicle crash deaths. The reason Congress has questions is because the issue first cropped up in 2001, but senior management seems to have been kept in the dark until January 31 of this year. It’s hard to understand that it would take more than 12 years for someone to realize there was a problem.
