Subaru Corp. said Tuesday it has found new cases of product data fabrication, bringing the total number of affected vehicles to 1,551, up from the previously reported 903, and prompting a revamp of its top management.

Yasuyuki Yoshinaga will step down as Subaru's president and also as CEO to take responsibility for the inspection scandal. He will become chairman without the right to represent the company and will focus on dealing with the misconduct.

The post of CEO will now be filled by Tomomi Nakamura, the incoming president, the automaker said. Their appointments will be effective June 22.
