Nissan has admitted that it has uncovered falsified data from car exhaust emissions tests at most of its Japanese factories.
The firm did not disclose how many cars were involved, but said emissions and fuel economy tests had “deviated from the prescribed testing environment”.
The carmaker added that inspection reports had been “based on altered measurement values”.
Nissan pledged there would be a “full and comprehensive investigation”.
It added that “appropriate measures” would be taken to stop any future recurrence.
