PARIS—Legal troubles are piling up for Carlos Ghosn after French carmaker Renault said April 3 it had flagged to judicial authorities serious problems with his expenses during his time as chairman of the company.

Renault’s statement suggests the company is toughening its approach to Ghosn, who it had long refrained from criticizing after he was arrested in November in Japan on charges of understating his income at Japanese carmaker Nissan, which he was chairman of too.
