The Yomiuri ShimbunNissan Motor Co. said Monday that it had tampered with data on fuel economy and exhaust emissions at its five plants in the country, including the Tochigi plant in Kaminokawa, Tochigi Prefecture.
The automaker altered data of 1,171 vehicles, which is more than half for which it conducted sample inspections.
The latest data falsification once again brought to the fore Nissan’s sloppy inspection practices. Last year, Nissan admitted workers without proper authorization had conducted final inspections on some vehicles. Nissan continued to commit the falsification even after the revelation of this scandal.
According to Nissan, the automaker deliberately tampered with fuel economy and gas emission data if figures measured during sample inspections on finished vehicles substantially deviated from standards set by the company. Nissan said the original measured figures meet standards set by the government.
It was also confirmed that, in some cases, Nissan made it appear that the inspections were properly carried out even though vehicles’ speed, and temperature and humidity levels in inspection rooms deviated from the range stipulated under the standards.
