  7. Suzuki/Mazda/Yamaha admit to falsified...

[YesAuto News] According to Japanese media reports, the Japanese Ministry of Land, Infrastructure, Transport and Tourism recently announced that three companies have conducted illegal operations in vehicle fuel consumption and emission tests, namely Mazda, Suzuki and Yamaha. This news has also become another case of fraudulent emissions from Japanese cars.

In view of Subaru and Nissan's exposure to rewrite data, Japan's Ministry of Land, Infrastructure, Transport and Tourism required 23 car and motorcycle manufacturers to conduct internal inspections. This time, problems were discovered during the factory inspections of new car quality management. Mazda, Suzuki and Yamaha tampered with the results of sampling inspections of new car exhaust and fuel consumption, and changed the original invalid data to valid. Among the 6,500 improperly tested cars, 6,401 were Suzuki, 72 were Mazda, and 7 were Yamaha engines.

Suzuki was exposed to cheating again after being exposed to fuel consumption fraud on May 18, 2016. The company admitted that it has started to use methods that violate national regulations to conduct fuel efficiency testing since 2010, involving the use of micro-cars and small cars such as Alto. A total of 2.1 million vehicles are included in the 16 models. Mazda and Yamaha were exposed for the first time.

On the afternoon of August 9, Suzuki held a press conference to explain the improper inspection data. Suzuki President Toshihiro Suzuki apologized for the impact of this incident on the public. Suzuki said that the reason for this phenomenon was that there was no managerial staff familiar with the inspection at the factory, and there was a loose discipline at the inspection site. Mazda and Yamaha have also made public apologies, but no recall plan has been announced yet.

This is not the first scandal in the Japanese manufacturing industry recently. In April 2016, Mitsubishi was the first to be found to have used improper means in fuel consumption testing to achieve better fuel economy than the actual situation; in October 2017, Nissan was exposed to the inspectors who participated in the vehicle factory inspection as unqualified, so it was recalled 1.2 million vehicles. After sampling the automotive products of its five factories in July 2018, Nissan admitted that the exhaust emissions and fuel consumption data of its 19 models sold in Japan were falsified. At the end of April 2018, Subaru disclosed an internal inspection report that showed that employees had tampered with exhaust emissions and fuel consumption data. In addition, Kobe Steel, Mitsubishi Materials and Toray Industries, as mainstream parts suppliers, also admitted to falsifying product data last year.
