TOKYO — Nissan revealed two new blows to its embattled management on Thursday, as it announced a recall of 490,000 vehicles in Japan and disclosed that its shareholders remained split over its chief executive, Hiroto Saikawa.

The recall over an electrical issue is the second largest of nine this year. The problem stems from a design flaw, but serves as a reminder of the troubled Japanese automaker’s struggles with quality as well as management issues. So far in 2019, Nissan has recalled more than 1.5 million vehicles in Japan.

Nissan has faced challenges on different fronts. The November arrest of the company’s former chairman Carlos Ghosn on allegations of financial wrongdoing exposed huge dysfunction in its governance. It has also suffered from plunging profits and a string of quality scandals.

No deaths or injuries have been reported in relation to the electrical problem. Nissan said a fault in the electrical system could lead to a risk of fire in some Japanese models of vans and minivans, including the Serena, the NV200 van and Cube.
