Japanese car manufacturers Toyota, Honda, Mazda, and Suzuki have admitted to faking emissions and safety tests. The Ministry of Land, Infrastructure, Transport and Tourism of Japan (MLIT) discovered these fraudulent activities following an investigation. The affected models from these companies will see halted production, shipments, and sales.

The MLIT launched its probe with the intent to scrutinize domestic automakers' compliance practices. Their findings concluded that all four automakers committed fraud in their type approval applications for various vehicle models. This has led to an immediate stop in the production and sale of these vehicles.

Toyota disclosed that it had submitted false data related to several safety tests impacting models such as the Corolla Fielder and Lexus RX. Internal investigations by Toyota revealed issues including tampering with crash test results. Despite this, the company confirmed that all affected vehicles comply with safety standards.

Similarly, Mazda's internal review uncovered tamperings such as modifications in engine control software meant to manipulate emissions levels in vehicles including the MX-5 RF and Mazda6. Despite these irregularities at the testing stage, production models reportedly meet all required safety norms.

Honda's admission included falsified data on noise levels in an extensive range of models like the CR-V and Odyssey. An internal audit indicated that discontinued vehicles were primarily affected but assured that current production cars are regulatory compliant.

Suzuki's infractions involved dishonesty in brake tests for its LCV version of the Alto produced between 2014 and 2017 where stopping distances were inaccurately reported to be shorter due to insufficient brake pedal pressure during tests. Suzuki attributed this wrongdoing to a rush in meeting deadlines without adequate testing.

Following these revelations, MLIT plans on-site audits focused on confirming if other models meet national vehicle regulations comprehensively. The automakers have also been instructed to provide information and support to affected owners as needed.

The investigation will halt the production, shipment and sale of the affected models currently offered in Japan and other markets around the world. It remains to be seen how quickly the Japanese authorities will be able to resolve the compliance issues and determine the appropriate penalties for the automakers' fraudulent actions.
