Nissan Motor has admitted that an internal review has revealed falsified emissions testing data in most of its factories in Japan. Nissan has not announced how many of its vehicles were involved in the controversy, though the company stated that inspectors used “altered measurement values” on emissions inspection reports.
This is the second controversy in less than a year for Nissan whose vehicle-inspection scandal had led to the recall of about 1.2 million vehicles. For now, Nissan’s current emissions problems are still a far cry from the scope of Volkswagen’s Dieselgate scandal, which resulted in a $25 billion fine to the German legacy carmaker. Nissan’s current emissions issues, if any, seem to be caused by the company’s mismanagement of its facilities and its workforce. Based on what Nissan has revealed so far, it appears that the company’s falsified emissions data were at least not the results of a deliberate effort.
Volkswagen, on the other hand, admitted to intentionally writing software to cheat emissions tests. From 2006 to September 2015, Volkswagen promoted its cars in the United States as “Clean Diesel” vehicles. Over that time, about 580,000 sedans, SUVs, and crossovers were sold by Volkswagen in the US under its flagship VW badge, as well as under its Audi, and Porsche brands. As the scandal broke, however, it was revealed that the exhaust control equipment in Volkswagen’s diesel vehicles was programmed to shut off as soon as the cars were off regulators’ tests.
Nissan’s announcement is the latest in a string of compliance scandals at carmakers including Mitsubishi and Subaru that has dented the reputation of Japan’s manufacturing sector.
