Nidec (TYO:6594) said a recent media report on quality issues was not based on an official disclosure, while confirming that internal reviews have identified suspected procedural irregularities in parts of its operations, according to a Wednesday filing on the Tokyo Stock Exchange.
The company said a comprehensive quality inspection, conducted under a reform committee set up in late October 2025, has found instances where materials, manufacturing processes and designs may have been changed without customer approval.
Nidec said no issues have been identified that would immediately affect product performance or safety. It also said discussions are ongoing on forming an external investigation panel, though no final decision has been made.
The company has begun engaging with customers to provide explanations and support consultations as it assesses the scope of the findings.
