Nissan and Renault's two-decade alliance, which also added Mitsubishi Motors Corp. in 2016, was jolted by the arrest of former Chairman Carlos Ghosn in November 2018. The French automaker owns about 43% of Nissan, while the Japanese manufacturer only holds 15% of Renault and zero voting rights. Any significant changes to their shareholdings would also run the risk of raising questions over the viability of the three-way alliance.
