Suzuki And Mazda Admit To Improper Emissions Tests In Japan

Japan's Suzuki Motor, Mazda, and Yamaha have admitted using false emissions data for some vehicles, the transport ministry said Thursday, in the latest product quality scandal to hit the country's auto sector.

All three have already complied with a request by the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) to conduct investigations into the matter.

In the Japanese cases, the carmakers have not broken any laws or prompted massive recalls.

Reuters, meanwhile, reported that Suzuki most often inspected vehicles with manipulated emissions data, adding that the company confirmed that nearly half of its 12,819 new auto inspections were improper dating back to 2012. The errors related to slight deviations in the speed of the vehicles during testing that should have invalidated the test results.

Suzuki, Mazda and Yamaha said they would take preventive steps, such as changing inspection devices so their staff can not rewrite the data.

They said incomplete emissions tests were done on some of its vehicles, but its officials certified the results as though the tests had been administered properly.


"Mishandlings found in so many vehicles were a serious problem, that we take very seriously", Suzuki Motor President Toshihiro Suzuki said, according to Reuters, apologizing for the trouble caused to customers and business partners.

At Mazda, of 1,875 cars subject to the sampling inspection, improper inspections were discovered in almost 4 percent since November 2014.

In a similar sample, Mazda uncovered inappropriate testing on 72 vehicles out of 1,875 units since 2014.

Both Mazda and Yamaha apologized.

Kobe Steel, Mitsubishi Materials Corp and Toray Industries - all key suppliers of motor parts to global manufacturers - admitted to product data fabrication previous year.

Numerous automakers, already hit by lackluster sales, have also been under pressure from U.S. President Donald Trump's proposed tariffs on imported vehicles.
