The alerts went off again for Toyota. The Japanese brand launched a new recall campaign that affects approximately 44,000 units of the 2024 Tundra pickup due to a possible internal defect in the 3.4-liter biturbo V6 engine. The situation is especially worrying because it is not an isolated case or a new failure for the company.

The problem had already appeared in previous campaigns related to Tundra and Lexus models, but now it is repeated even after Toyota claimed to have strengthened its manufacturing processes. That is precisely what is most disturbing among owners and specialists in the sector.

Most of the affected units are located in the United States, although the recall also involves vehicles sold in different Latin American markets. The Tundra remains one of Toyota's most important models within the large pickup segment, so any inconvenience of this type generates a strong impact.

The source of the problem is still the engine

As explained by Toyota itself, the failure is related to metal residues that could have remained inside the engine after the machining process during manufacturing.

These particles would have the ability to cause severe damage to internal components, especially the number 1 main bearing. When that occurs, wear can progress rapidly leading to major mechanical failure or even total destruction of the engine.

The brand recognized that drivers could detect some signs before a complete breakdown. Among the most common symptoms are strange noises, unusual vibrations, loss of power, difficulty starting or irregular vehicle operation.

Toyota also warned that if the engine loses power while the truck is traveling at high speed, the risk of an accident significantly increases.

It is not the first time that Toyota faces this scenario

The new retirement does not come alone. In May 2024, Toyota had already launched a campaign involving approximately 102,000 vehicles between the Tundra and Lexus LX manufactured between 2022 and 2023.

Months later, in November 2025, the problem escalated again and the company expanded the review to another 127,000 vehicles, also incorporating Lexus GX models.

That the same problem appears again despite the additional controls implemented by the brand raises doubts about the real effectiveness of the solutions applied so far.

Replacing entire engines shows the seriousness of the case

Toyota assured that it has already managed to repair more than 77,000 units corresponding to the first recall announced in 2024. However, many of these repairs directly involved replacing the entire engine, one of the most expensive solutions that a manufacturer can face.

This detail makes clear the level of severity of the detected defect. It's not just a software update or a minor part replacement.

The company also reported that it is still working on a definitive solution for this new campaign and for the units affected in the expanded 2025 recall. Owners will begin to be contacted progressively once repairs are ready for each model involved.

Meanwhile, Toyota advises paying attention to any strange behavior of the engine and immediately go to an official dealer if suspicious symptoms appear.

Owners can also check if their vehicle is part of the recall using the VIN number on official Toyota channels or through the NHTSA database in the United States.
