The Japanese government ordered Toyota Motor on Wednesday to make “drastic reforms” after discovering new violations in the automaker’s vehicle certification procedures.

In a so-called corrective order, the Transport Ministry said on-site inspections had uncovered widespread, intentional misconduct and irregularities in seven additional models that had not been previously disclosed.

Toyota ™ said the corrective order instructed it to “make drastic reforms to ensure appropriate certification operations.”

The automaker added It was in the process of confirming compliance with requirements for the models involved, and that customers did not need to stop using affected vehicles.

In July, Toyota said it had not found any new cases of wrongdoing in car model certification applications beyond the ones it had already reported in June.

Toyota and four other vehicle makers admitted in June they had submitted either flawed or manipulated data when applying for certification of vehicles.

Toyota’s wrongdoing involved three production models – the Corolla Fielder, Corolla Axio and Yaris Cross – and discontinued versions of four other models, including one sold under the luxury Lexus brand.

Toyota said it was planning to resume production of these models from the beginning of September after the Transport Ministry confirmed they met compliance requirements.

The Japanese automakers conducted the investigation after the ministry ordered industry-wide checks of certification practices following a safety test scandal at Toyota’s Daihatsu compact car unit.

The ministry said six of the seven additional Toyota models with irregularities were also certified in other countries, and it had alerted overseas authorities about the issues.

Four of the additional models – a minivan sold under the names of Noah and Voxy, and the RAV4, Harrier, and Lexus LM – are still in production by Toyota while three are no longer manufactured. (CNN)
