Toyota is expanding its recall efforts to address a recurring issue with its 3.5-liter turbocharged V6 engines, announcing this week that an additional 127,000 Toyota and Lexus vehicles are being brought back for inspection. The problem stems from the possibility of leftover machining debris – tiny metal shavings – remaining in the engines during the manufacturing process.

The Risk: Potential for Catastrophic Engine Failure
The presence of these small particles is not a minor concern. They can disrupt the engine’s lubrication system, potentially leading to serious problems. This includes rough idling, knocking noises, difficulty starting, and, most concerningly, total engine failure while the vehicle is in motion.
Affected Vehicles and Models
This recall affects the following vehicles manufactured between 2022 and 2024:
- Toyota Tundra: 2022-2024 models
- Lexus LX: 2022-2024 models
- Lexus GX: 2024 models
Crucially, this recall only applies to models equipped with the non-hybrid version of the twin-turbo V35A V6 engine.
A Recurring Problem: History of the Recall
This latest recall echoes a previous announcement from 2024, which impacted over 100,000 Tundra and Lexus LX vehicles. Both instances are linked to the same root cause: inadequate cleaning during engine manufacturing, leading to residual metal particles within the engine’s oil passages.
Why This Matters
The problem highlights a potential lapse in quality control at Toyota’s manufacturing facilities. While these shavings are microscopic, their presence can restrict oil flow and ultimately compromise engine performance and reliability. This isn’t just inconvenient; a sudden engine failure can pose a serious safety risk to drivers and other motorists.
Toyota’s Response and Future Remedy
Toyota acknowledges the issue and is “currently developing the remedy.” However, this phrasing is reminiscent of the previous recall, where it eventually became clear that Toyota would need to implement a drastic solution. In the earlier case, the automaker ultimately agreed to replace over 102,000 engines in affected vehicles, signaling the severity of the underlying problem.
Context and Trends
This situation underscores the importance of rigorous quality control in automotive manufacturing. The prevalence of recalls related to manufacturing debris, though statistically rare, is an ongoing challenge for automakers globally. Toyota’s dedication to building reliable vehicles is a key selling point and a cornerstone of its reputation; this recall presents a test of that commitment.
The root of the issue is a flaw in the production process that could lead to potentially serious consequences for drivers. Addressing this thoroughly and effectively is crucial to maintaining Toyota’s reputation for reliability.
In conclusion, Toyota’s latest recall affects a significant number of vehicles and represents a continuation of a previous issue. While the specific remedy is still under development, the automaker’s history suggests a potential engine replacement may be on the horizon, emphasizing the importance of a robust and thorough fix.
