Nissan admits falsifying emissions tests in Japan

In a recent statement, Nissan has confessed that it altered the emission controls of some car models made in Japan.


The Japanese car manufacturer Nissan acknowledged on Monday that it had altered some of the results of the anti-pollution tests on the models of the factories installed in Japan. The measurements of gas emissions and fuel use tests were not carried out according to the "established protocol" and the inspection reports were based on altered values, according to Nissan in a statement, after it was submitted to the Japanese authorities. Despite this, the company claims that most of its vehicles (with the exception of the GT-R, a sports car of the brand) do comply with the data in the catalogues.


These disclosures arise from controls initiated in September 2017, after being asked to do so by the Japanese authorities. Nissan reports that they have detected "misconduct for vehicles produced at their national vehicle production plants and those of their affiliates". The company reports that the fraud was based on the modification, by an undetermined number of employees, of the conditions under which these tests are carried out, in terms of temperature, ambient humidity or the speed at which the vehicles are subjected to, for example. Other times the tests did conform to the guidelines set by the law, but the results were changed directly.


Nissan, said that the number of vehicles affected by these malpractices currently stands at 1171, produced in five different factories from 2013 to a few weeks ago. Illegality affects only cars sold on national territory, not those exported.


Nissan is once again in the spotlight of the emissions scandal. This case is not the same as the one that was uncovered at the German manufacturer Volkswagen - which went so far as to use illegal software to falsify the laboratory controls of thousands of cars. But it does mean a new infringement of the system of checks on cars.
