Kobe Steel, the disgraced Japanese metal supplier, apparently falsified quality data for its products for over 10 years, the company now admits. Some of those products were sheetmetal and aluminum components used by a slew of automakers, among them American, Japanese, French, German, and Swedish manufacturers.

Makers of trains and airliners also made use of the metals, the strength and durability of which is now in doubt. This week, the European Aviation Safety Agency warned against components made by Kobe Steel.

While Boeing and Airbus inspect their aircraft, automakers are doing the same. Ford has said there’s no reason to be concerned, as Kobe product only went into the hood of a Chinese-market sedan. Now, four other automakers have given their vehicles a clean bill of health.

It’s often hard to remove an ingredient after the cake’s emerged from the oven. Because of this, news of Kobe Steel’s falsified inspection reports no doubt came with a fair bit of nervous collar tugging for executives at several automakers.

The Japanese company, which has subsidiaries in numerous countries, is a go-to supplier for the automotive and aircraft industries, providing steel, copper and aluminum components to companies as diverse as Ford and Boeing. Last week, Kobe admitted to selling substandard (or suspected substandard) materials to 500 companies, among them Ford, Volvo, Toyota, Honda, Nissan, Mitsubishi, and possibly Mazda.

Oh, and Mercedes-Benz, Tesla, General Motors, Hyundai, and Renault.

Maybe you’ve heard of them.

As Ford prepares to stake its future on an aluminum F-150, Toyota is looking to do the same for at least a single part on its best-selling vehicle.
