Nissan has admitted misconduct in its exhaust emissions testing procedure on 19 cars in Japan and submitted related information to the Japanese ministry of land, infrastructure, transport and tourism.
The brand alleges to have discovered ‘nonconformities’ in its final inspection process back in September 2017 and has since carried out an internal investigation into how the discrepancies came about.
A statement released by Nissan admits that emissions and fuel economy tests “deviated from the prescribed testing environment” and the “creation of inspection reports based on altered measurement values”.
The misconduct was discovered through “proactive initiatives to prevent recurrence of such issues”; the initiatives were launched following the nonconformities discovered last year.
Nissan has commissioned a law firm to investigate the issue and implemented its own preventative measures to ensure that a similar issue doesn’t occur in the future.
