The Toyota Group has temporarily halted the delivery of 10 car models due to irregularities in the certification process related to diesel engines produced by Toyota Industries Corporation (TICO). This issue affects vehicles from the Toyota, Lexus, Mazda, and Hino brands.
Toyota stated that all vehicles are equipped with diesel engines that have an ECU different from the engines used in testing. In a statement issued on January 30th, Toyota explained that a branch used software to measure output power, which made the “values appear smoother and less variable.” The automaker told Autonews that it does not affect engine performance during emission tests.
The Japanese automaker confirmed that they have reconfirmed the engines produced for mass-produced models and found that they meet output standards. This means that vehicles on-site can continue to be used. However, TICO has suspended the transportation of engines and Toyota has halted the delivery of affected vehicles.
This will affect customers in Japan, Asia, the Middle East, Africa, and Europe, where these vehicles are sold. In total, approximately 84,000 vehicles worldwide have been sold with engines in the range of data and engines that began shipping in 2020. Toyota said they will work with regulatory agencies to address the issue and allow witnesses to be present during tests of engine power. Reuters reported that the Japanese Ministry of Transport will conduct an on-site investigation at TICO’s Hekinan plant, where the engines are produced.
This is just the latest certification issue to affect one of Toyota’s business partners. In 2022, Hino was found to falsify emission data for its commercial trucks, and shortly after, Daihatsu Motors admitted issues with the safety of some of its vehicles. Both issues affected Toyota vehicles.
Toyota President Koji Sato apologized to customers during a press conference in Tokyo, saying, “We sincerely apologize for causing a major inconvenience to our customers.” Sato added that the company is committed to resolving the issue as quickly as possible.
The issue came to light after Toyota commissioned an independent investigation committee to look into abnormalities with forklifts and construction equipment, but ultimately found that it affected vehicles such as the Toyota Land Cruiser Prado, Hilux, Fortuner, and Land Cruiser 300, as well as the Lexus LX500d, Hino Dyna, and Mazda Bongo Brawny truck
