Toyota is facing another problem as it suspends production of certain models, including the Fortuner and Innova. The suspension came after the company discovered irregularities in the diesel engine certification tests conducted by its subsidiary, Toyota Industries. A special investigation committee found abnormalities in the power output tests conducted to certify the three diesel engine models. Toyota, the world’s best-selling carmaker, announced that 10 models using these diesel engines are affected globally, including the Fortuner, Innova, Hiace van, Hilux pickup, Land Cruiser 300 Series SUV, and Lexus LX500D.
In addition to dealing with the ongoing scandal surrounding its subsidiary Daihatsu, Toyota is currently working to rectify another case of misconduct related to crash test safety tests. Toyota has been in close communication with regulatory authorities to resolve the issue, and it is also conducting new engine certification tests, which will be overseen by the appropriate authorities, if necessary.
During a press conference in Japan, Koichi Ito, President of Toyota Industries, explained that the issue arose due to a lack of communication with the Toyota Group and insufficient coordination regarding the testing procedures that needed to be followed.
Toyota Industries stated that it has sold approximately 84,000 affected diesel engines as of March 31, 2023. Koji Sato, CEO of Toyota, revealed that the company uses 36,000 affected engines each month worldwide, equivalent to 432,000 engines per year. However, Toyota’s spokesperson was unable to provide immediate information on the number of affected vehicles sold in previous years.
In Japan, production lines at four plants have been temporarily suspended. Toyota confirmed that both the affected engines and vehicles meet the required engine performance standards.
The special investigation committee discovered that the electronic control units used in power output tests were different from those used in the production process. The committee initially focused on certification regulations relating to emission performance of forklift and construction machinery engines and confirmed misconduct in this area as well.
The Ministry of Land, Infrastructure, Transport and Tourism in Japan will conduct an on-site investigation at Toyota Industries’ Hekinan plant in Aichi Prefecture on January 30, 2024, where the company manufactures automobile and industrial engines.
Toyota currently holds nearly 25% of Toyota Industries’ shares. Conversely, the supplier owns around 8% of Toyota’s shares. Toyota Industries is a key subsidiary of the Toyota Group.
