Toyota was splashed by a new scandal: The Toyota group announced that it had been informed of irregularities in approving certain diesel engines. Produced by its subsidiary Toyota Industries Corporation, they notably equip the Hilux pick-up.

The Toyota group makes a series of revelations. We have learned in recent months that its subsidiary Hino Motors, dedicated to heavy goods vehicles, had falsified polluting emissions values. The manufacturer Daihatsu, which is also part of the Toyota group, has rigged crash tests for several decades, for vehicles produced under its brand, but also for models badged Toyota, Subaru, and Mazda.

The latest controversy concerns the subsidiary Toyota Industries Corporation, which notably produces forklifts and has already been involved in an emissions scandal. This time, it is not directly the polluting emissions from the engines that are being singled out. Homologation irregularities were, however, observed and made official by the Toyota group this Monday, January 29, 2024.

Rigged calculators to fix approval values

Thus, “during certification tests, the power of the engines was measured using calculators whose software differed from that used for mass production, to measure the results so that the values ​​appeared smoother and presented less of variations”, explains Toyota.

The models concerned, whose production started in 2017, were therefore checked in a configuration different from that of the vehicles leaving the factory. This can raise many concerns, going beyond the power values ​​which, according to Toyota, still meet “engine performance standards”.

Ten models are affected by this scandal, which concerns three different diesel engines (1GD, 2GD, and F33A). These blocks are produced by Toyota Industries and installed on board Toyota, Lexus Hino, and Mazda models. The only model sold in France tainted by this scandal is the latest generation Hilux pickup.

Toyota assures its customers that “there is no need to stop using the affected engines or vehicles.” The group has, however, paused the supply of the engines concerned and the marketing of versions of its models which are equipped with them, which represent around 36,000 vehicles assembled per month worldwide.

After the cessation of production of vehicles developed by Daihatsu, which constitute a large part of the group’s catalog in some of its key markets, particularly in Asia, this measure should further weaken Toyota and allow other manufacturers to grab profits from its market shares.
