Daihatsu Motor Co., Ltd.

Daihatsu Motor Co., Ltd. (Daihatsu) announced on April 28, 2023 that it had committed procedural irregularity in approval application for the side collision tests (UN-R95) for vehicles destined for overseas markets. During an in-house inspection, we confirmed another procedural irregularity in the certification procedure for the hybrid electric vehicle (HEV) pole side collision tests (UN-R135) for Daihatsu Rocky and Toyota Raize. We therefore stopped shipping and selling these models today.
We deeply apologize to our customers and other stakeholders for causing great inconvenience and concern.

The pole side collision test (UN-R135) must be performed on the left and right sides of the vehicle and the test data must be submitted. During the tests, the passenger seat side (left) was tested in the presence of witnesses. However, we submitted the left-side data for the right-side driver’s seat data from the in-house tests.

We are currently in the process of confirming our next actions and will report on them.

Daihatsu believes that these procedural irregularities in the area of vehicle safety are unacceptable. Daihatsu believes that these irregularities occurred as a result of management’s inability to attend to the frontline, compromising compliance and the fostering of a sound corporate culture. Consequently, the company lost sight of proper car manufacturing, causing such irregularities. Daihatsu will work with determination to change the company to ensure that the same mistakes will never be made again. The company will start by stopping and thoroughly investigating the background, environment, and true causes that led to these irregularities being committed. It will then work to make improvements, prevent recurrence, and clean up the company. In doing so, Daihatsu will ensure that these irregularities are not merely a single business act, but rather a reform that is linked to the philosophy and action guidelines of the entire corporate group in order to achieve reform. The company will fully cooperate with the Third-Party Committee’s full clarification of the incident and its root cause analysis. Management will immediately focus on communicating with the frontline and creating a workplace where people can talk frankly and honestly.
