Emission scandals

Nissan discovers false emissions data at most of Japan factories
Misconduct related to exhaust emissions found by Japanese automaker

Nissan, which was involved in a vehicle-inspection crisis last year, said an internal check by the company found employees had falsified exhaust emission and fuel-economy data at five local factories.

The way the tests were conducted deviated from prescribed norms, the automaker said in a statement on Monday, adding it also found employees filed inspection reports based on altered measurements. This data manipulation happened to the sampling test, part of the final car inspection process, the automaker said.
