It only affects cars sold in Japan, not the US.
Late last year, both Nissan and Subaru admitted to decades of « flawed » vehicle inspections for cars sold in Japan. It appears that wasn’t the only misstep Nissan committed in its home country.
Nissan has admitted to incorrectly measuring emissions and fuel economy for 19 different models it sells in Japan, Reuters reports. The automaker claims that, of some 2,200 sample tests across six Japanese plants, it found data falsification in 1,200 tests across five plants.
Japanese regulations require automakers to stick to specific speeds and durations during its emissions tests. Per Reuters, Nissan claims that it found data that did not line up with what the Japanese government wants, and in some cases, the testing equipment wasn’t even calibrated correctly. It also overstated fuel economy data.
