New emissions troubles emerge at Nissan
Today, Nissan reported misconduct within its final vehicle inspection process to the Japanese Transport Ministry. More specifically, the company had engaged in emissions and fuel economy tests that deviated from the normal testing procedure required by the Japanese government. An investigation into nonconformities in the final inspection progress has been ongoing since Nissan discovered problems during voluntary compliance checks last September.
The latest news comes after revelations that uncertified inspectors had signed off on tests for decades. In fact, workers had been borrowing the “hanko”, or stamps used for signatures in Japan, of certified personnel since 1979, according to a CBS News report of Nissan’s claims. Inspectors also created reports on emissions and fuel economy based on altered measurement values, according to Nissan. The misconduct took place at Nissan’s domestic production plants in Japan, and specifically affects Japanese models.
Investigation is ongoing
Nissan said in a recent statement, “Proactive initiatives to prevent recurrence of such issues have led to the discovery of this misconduct, for which the company is regretful.” The company promised to continue its investigation into the issue. The company hasn’t recalled any vehicles as the issue didn’t compromise the safety of the affected models. Inspectors also verified that the numbers were in line with those presented in product catalogs.
Again, the exhaust gas measurement misconduct only affects Japanese-market models, according to Nissan. However, this is the latest in a string of scandals to hit Japanese automakers. Subaru recently admitted its inspectors at Japanese plants tampered with fuel economy data. Two years ago, Mitsubishi also admitted to using improper methods to test fuel economy for 25 years.
