In this video, Motley Fool analysts Austin Smith and Blake Bos follow due diligence by discussing the reasons to sell General Motors (NYSE:GM) shares.

The first reason to be bearish on GM's stock is the company's ongoing turnaround plan, the success of which is vital. History shows that turnarounds more often fail because they are so difficult to execute. In the case of GM, this process is not made any simpler due to the size of the company, the complexity of manufacturing operations, and the amount of lost ground it still has to make up. The second fear is related to the GM's CEO, Dan Akerson, and his ability to change the inflexible and tight culture of the company. The last reason concerns its lost market share during the bankruptcy filing and the tight competition from other car makers to capture more market share.
