Nidec established an external lawyer committee Wednesday to investigate suspicions that the company changed product designs and manufacturing processes without customer consent [1, 2].
This development threatens the reputation of one of the world's largest motor manufacturers, as quality assurance is fundamental to the trust between industrial suppliers and their global clients.
President Mitsuya Kishida apologized for the lapses and said that the company is investigating the facts and the underlying causes of the misconduct [1, 2, 3]. The suspected irregularities involve more than 1,000 cases of unauthorized design changes and the improper handling of inspection data [1]. These issues occurred across multiple production sites within Japan, including Nidec headquarters and related factories [1, 5].
To ensure an impartial probe, Nidec appointed a committee consisting of 13 members [1]. This group includes 11 new appointees and 10 outside directors [1]. The company aims to complete the investigation by the end of August 2026 [2].
Kishida said that quality is the foundation of the group as a manufacturer and that the company takes the situation seriously [1]. The investigation seeks to uncover the root causes of the quality failures and implement a total refresh of the corporate culture to prevent future occurrences [1, 2].
The company is now facing pressure to explain how such a high volume of unauthorized changes bypassed internal controls. The scale of the suspected misconduct suggests a systemic failure in reporting and compliance across its domestic operations [1, 5].
“Quality is the foundation of the group as a manufacturer, and we take this extremely seriously.”
The scale of the suspected misconduct, exceeding 1,000 instances, indicates that these were not isolated errors but likely a systemic failure in Nidec's quality management systems. By appointing a committee dominated by outside directors and external lawyers, Nidec is attempting to signal transparency to shareholders and clients to avoid a broader loss of contracts. The outcome of the August report will determine whether the company requires a total overhaul of its production governance.
