TOKYO - The revelation that Japan's third-biggest steelmaker Kobe Steel Ltd's fabricated data for some of its aluminum and copper products has left affected manufacturers scrambling to pin down the potential impact.
Automakers affected by Kobe Steel's announcement include Toyota Motor Corp, Honda Motor Co, Nissan Motor Co, Mazda Motor Corp Subaru Corp and Mitsubishi Motors Corp, the respective companies confirmed.
Japan's largest automaker Toyota said the compliance breach was a "grave issue", adding that Kobe Steel's products were used in vehicle doors and hoods.
The automaker is grappling with its own compliance failures, recalling all new cars sold in Japan in the last 3 years after discovering final vehicle inspections were not performed by authorized technicians.
Honda said doors and hoods are affected, while Subaru said vehicles and aircraft are affected.
Mitsubishi Heavy Industries said Kobe Steel products were used on its Mitsubishi Regional Jet and rockets, including the H-2A rocket launched on Tuesday morning to put a navigation satellite into orbit. The rocket cleared all safety checks before launch, the company said.
Heavy machinery maker IHI Corp said affected products were used in its jet engines.
IHI is a supplier for engines used on Boeing Co aircraft and in Japan's defense and aerospace industries. The company did not say which engines used the affected products.
