Toyota Motor Corp. said Friday that the final report of its internal investigation found no more cases of improper vehicle testing for certification other than irregularities in testing seven models found earlier.
Like other Japanese auto-related manufacturers, the world's biggest automaker by volume was looking into the certification process of all its domestic models over the past 10 years at the request of the transport ministry after data fraud was discovered at Daihatsu Motor Co. and Toyota Industries Corp., both Toyota group companies.
The Ministry of Land, Infrastructure, Transport and Tourism said the same day it will examine the final report and decide whether any administrative punishment or instruction is needed.
Toyota said last month that it found irregularities in testing seven models for certification, and the ministry imposed a shipping ban on three of the seven that are currently on the market. Regulators will decide on the lifting later.
Shipments of three other models of Mazda Motor Corp. and Yamaha Motor Co. were also suspended after the two admitted to improper testing. The ministry lifted the ban last week after confirming the affected vehicles' safety and environmental standards according to the government's regulations.
The vehicle certification scandal also involved Honda Motor Co. and Suzuki Motor Corp., which had admitted to not conducting vehicle tests for their past models as required under the government's rules.
Japan's antitrust watchdog said separately Friday that a Toyota subsidiary forced 49 subcontractors to store auto parts molds without paying the costs in violation of the subcontract law.
Toyota Customizing & Development Co., a maker of parts, ambulances and racing cars in which Toyota has a 90.5 percent stake, coerced the suppliers to retain a total of 664 molds and inspection instruments for parts at least since July 2022, although it did not plan to place new orders, according to the Japan Fair Trade Commission.
