Notice of Additional Procedural Irregularities by Daihatsu in Certification Applications, Shipment Suspension of Vehicles Sold by Toyota, and Responses Going Forward (as of December 17)
Toyota City, Japan, December 20, 2023―Today, Daihatsu Motor Co., Ltd. (Daihatsu) received the investigation results of the Independent Third-Party Committee (chaired by Makoto Kaiami) commissioned by Daihatsu regarding procedural irregularities, which it reported to Toyota Motor Corporation (Toyota) in turn. The investigation found new irregularities in 174 items within 25 test categories, in addition to the door lining irregularity in April and the side collision test irregularity in May. These encompassed a total of 64 models and 3 engines of vehicles (total of models currently being produced, developed, or ceased in production), including 22 models and 1 engine being sold by Toyota.
We would like to express our sincere apologies for the inconvenience and concern this has caused to all stakeholders, including customers.
In response to these findings, Daihatsu decided today to temporarily suspend shipments of all Daihatsu-developed models currently in production, both in Japan and overseas. Toyota has also decided to temporarily suspend shipments of the affected models.
Over the course of the investigation by the Independent Third-Party Committee, Daihatsu received some information regarding models that may have been involved in the procedural irregularities. In response, Daihatsu has been conducting one-by-one in-house technical verifications and actual vehicle testing for these vehicles to ensure that their safety and environmental performance meet legal standards.
In the final stage of the investigation, it was discovered that a different airbag control unit (ECU) than the mass-production model was used for the airbag tests for Daihatsu Move / SUBARU Stella, Daihatsu Cast / Toyota Pixis Joy, Daihatsu Gran Max / Toyota Town Ace / Mazda Bongo. Although technical verification confirmed that the airbag met standards of occupant protection performance, in the course of testing, it was found that the “Safety Performance Standard for Occupant Evacuation (Unlocking)” in the side collision test of Daihatsu Cast / Toyota Pixis Joy may not comply with the law. At this time, we are not aware of any accident information related to this matter, but we are conducting thorough technical verification and investigating the cause to take necessary measures as soon as possible.
For other cases, we have confirmed that the performance standards specified by the regulations are met, and the validity of the verification results and process has also been confirmed by TUV Rheinland Japan (TRJ), a third-party certification organization.
Certification consists of having the national authorities inspect and confirm that vehicles meet various standards so that customers can drive their vehicles with peace of mind. We consider certification to be a major prerequisite for doing business as an automobile manufacturer. We recognize the extreme gravity of the fact that Daihatsu’s neglect of the certification process has shaken the very foundations of the company as an automobile manufacturer.
Since 2013, Toyota has been increasing the number of OEM models it receives from other companies, mainly compact vehicles. We deeply regret that the development of these vehicles may have been a burden on Daihatsu and that we were not aware of the situation with the company’s certification operations.
Daihatsu has informed us that, going forward, it will clarify the situation with the authorities and take appropriate action under their guidance. It will also thoroughly investigate whether there have been any other similar cases to ensure customer safety first and foremost. We at Toyota will also fully cooperate with this investigation.
We believe in order to prevent recurrence, in addition to a review of certification operations, a fundamental reform is needed to revitalize Daihatsu as a company. This will be an extremely significant task that cannot be accomplished overnight. It will require not only a review of management and business operations but also a review of the organization and structure, as well as a change in human resource development and awareness of each and every employee. Toyota will provide our full support to Daihatsu’s revitalization so that it can return to its roots as the “compact mobility company” that Toyota and Daihatsu are striving for it to be, as well as regain the trust of all stakeholders.30 enero, 2024 a las 19:3330 enero, 2024 a las 20:46

Certification Irregularities at Toyota Industries
Toyota City, Japan, January 29, 2024―Today, Toyota Industries Corporation (TICO) reported to Toyota Motor Corporation (Toyota), which had commissioned TICO to develop diesel engines for automobiles, that it received a report from the special investigation committee (chaired by Mr. Hiroshi Inoue) that was commissioned to investigate potential irregularities of certification regulations related to inappropriate domestic emissions certification of engines for forklifts and construction machinery.
The investigation found that irregularities occurred during the horsepower output testing for the certification of three diesel engine models for automobiles that Toyota had commissioned to TICO. During certification testing, the horsepower output performance of engines was measured using ECUs with software that differed from that used for mass production so that results could measure to make values appear smoother with less variation. Ten vehicle models are using the affected engines globally, including six in Japan.
We have re-verified the mass-produced products manufactured at the plant and confirmed that the affected engines and vehicles meet engine performance output standards. Therefore, there is no need to stop using the affected engines or vehicles. However, we deeply apologize to our customers who have been supporting affected vehicles and waiting for a long time, and also to all other stakeholders for the significant inconvenience and concern that this has caused.
Based on the results of the investigation, TICO decided today to temporarily suspend shipments of the affected engines. Toyota has also decided to temporarily suspend shipments of vehicles equipped with the affected engines. Going forward, we will provide detailed explanations to the authorities and promptly proceed with appropriate measures, including conducting testing in the presence of witnesses if appropriate.
Certification consists of having the national authorities inspect and confirm in advance that vehicles meet various standards so that customers can drive their vehicles with peace of mind. We consider the appropriate process of certification to be a major prerequisite for doing business as an automobile manufacturer. We recognize the gravity of the fact that the repeated certification irregularities at TICO, following those at Daihatsu, have shaken the very foundations of the company as an automobile manufacturer.
TICO has informed us that they will start by providing detailed explanations to authorities regarding these findings and proceed with measures under their guidance in the hopes of regaining the trust of customers and other stakeholders as a manufacturer worthy of certification.
In addition, restructuring the relevant business will require a change in the mindset of all individuals, from management to employees, as well as a drastic reform of corporate culture. Such tasks cannot be accomplished overnight. Hence, as the party responsible for transferring the diesel engine business, Toyota will continue to provide support toward the revitalization of TICO’s engine business.
Furthermore, as the commissioner of these tests, we regret that we were not sufficiently attentive and aware of the fact that the procedures were not carried out in accordance with laws and regulations. Going forward, we will be involved in all company-wide activities to help rebuild TICO and review the situation to thoroughly ensure that safety and quality are the top priorities.
