The personality based governance under Carlos Ghosn is seen as a problem now that Mr. Ghosn is in a jail cell in Tokyo and under investigation by Japanese prosecutors. Mr. Ghosn faces charges that he under reported his deferred pay over a five year period to 2011. 

The Economist magazine points out the other problems that might have led to to the authorites being informed about the failure of Nissan to make the internal audits. This relates to the activities  of Mr. Ghosn to arrange a possible takeover by Renault through a merger. Nissan owns only 15% non voting stake in Renault, and Renault by comparison owns a 43.4% ownership in Nissan. The French government has a 15% stake in Renault and efforts were made by Mr. Macron, as Economy minister, to secure double voting rights for long term shareholders such as the French government.

This leaves the Japanese government and Nissan reluctant to see the move to Renault's takeover. The French government left with suspicions on the reasons for Mr. Ghosn's removal now less likely to cede control over the joint venture.

The jet setting high flying ways of executives such as Mr. Ghosn with the company's identity being defined by their activities are also coming under much criticism. The CEO of Chrysler Mr. Marchionne was gravely ill at 66 following a decade of deal making, with chain smoking, leading to a severe illness. Renault under Ghosn rescued Nissan in 1999, Fiat under Marchionne rescued Chrysler in 2009 with U.S. government help. The Economist magazine points out the Nissan alliance with Renault is now tarnished by another high flying executive.
