Nidec (TYO:6594) said a company-wide quality inspection identified suspected improper conduct involving changes to materials, processes and designs without customer approval, according to a Thursday filing on the Tokyo Stock Exchange.
The company said the inspection was being conducted as part of efforts by its Reform Committee, which was established on Oct. 30, 2025, to strengthen internal management systems. Nidec said no issues have been identified at this stage that would immediately affect product functionality or safety.
The company said it was considering setting up an investigation committee comprising external experts, although no decision had been made. The statement came after Nikkei reported on quality-related matters at the company.
Nidec said it had started contacting customers to provide explanations and consultations, and planned to formally decide on and disclose its response to the suspected improper conduct and related matters later Wednesday.
