More Japanese Automakers Caught Cheating On Emissions Tests - Was The Entire Industry In On The Deception?

More Japanese Automakers Caught Cheating On Emissions Tests - Was The Entire Industry In On The Deception?
Mazda, Suzuki and Yamaha improperly tested vehicles for fuel economy and emissions, the Japanese government said on Thursday, in the latest cases of data falsifications by the nation's manufacturers.

The government had ordered the automakers to make checks after revelations of improper testing at Subaru and Nissan last year.

Believe it or not - these "Discoveries" are being made by the Manufactures themselves- and while they were governmentally ordered it amazes that Japan allows manufacturers to investigate themselves and expects an honest reply!

At this point we do not know what the infractions were - and how far from required they were. That would interest me.

Many of the "errors" were simply paperwork issues, and not actual cheats like VW did with diesel emissions. Sometimes the numbers reported were worse than actual. And all of it was related to domestic market requirements only. None of them had any impact on the exported models.

I'm with TomM on this. I'd also like to know the details of the infractions.
atc98092 - Where in the article did you read that many of the issues were simply just paperwork? Their tests were improperly executed which in turn provides inaccurate results / false data. Were they claiming to be more efficient and emitting less GHG?
Sounds like you’re willing to just slap the hands of the Japanese brands but go for the jugular if it was a German brand.

"The government had ordered the automakers to make checks after revelations of improper testing at Subaru and Nissan last year.

Suzuki and Mazda cleared vehicles for emissions or fuel efficiency even in cases where they were tested under invalid conditions, the ministry said in a statement. The ministry looked at tests done for different periods at the two automakers, and at motorcycle maker Yamaha, stretching back to 2012 in Suzuki's case.

Suzuki, Japan's fourth-largest automaker, said that of 12,819 sample cars tested for fuel economy and emissions since June 2012, around 50 percent had been inspected improperly"

Sorry, I should have been more clear. The issues with Nissan and Subaru only dealt with domestic product, and was in most cases a paperwork/certification issue. It wasn't that the cars themselves emitted higher than allowed. For these new reports, I didn't mean to imply it was the same issue, but since again is only for the JDM product, it's certainly possible.

This one statement seems to possibly point to the same thing: "Suzuki said it did not find any significant problems with actual emissions and fuel economy performance and therefore planned no recalls."

I suppose we can "take their word for it" for now until an independent test is done and the results are released. If that ever happens.
