Strong new models like the Chevy Impala have boosted GM's image -- but the stigma of its 2009 bailout still lingers, and could come back to haunt GM soon. Photo credit: General Motors Co.

As part of the deal to repay its $49.5 billion bailout, General Motors (NYSE:GM) gave the U.S. Treasury a lot of stock -- more than 500 million shares. The government has been selling its shares for several months now. Originally, it was expected to be done selling sometime next year -- but it looks as if the feds' selling plan is ahead of schedule.

GM's CEO, among others, is saying that the government could sell the last of its GM stock before the end of 2013. What's the deal? In this video, Fool contributor John Rosevear looks at the latest on the government's plan to sell off its shares -- and at the big problem GM could be facing once the U.S. Treasury is no longer a GM shareholder.
