According to Toyota, it recalled over 250,000 vehicles because initial factory cleaning updates failed to remove all manufacturing debris from affected engines. Toyota Tundra owners driving 2022–2024 third-generation trucks with the 3.4L twin-turbo V6 engines are among those affected. Machines can fail; even manufacturers can make unintentional mistakes. But when something goes wrong, awareness can make all the difference. As a user, knowing your car's status helps you respond appropriately before the situation worsens.
In this blog, we break down what critical information Toyota Tundra owners need to know, including:
Manufacturing debris is clearly the root cause of Toyota Tundra engine problems, left inside certain V35A engines.
According to Toyota's submission, during manufacturing, some debris is unintentionally left uncleared and becomes the primary culprit contaminating the engine's crankshaft main bearing.
When the crankshaft main bearing is affected, it can develop a rippling effect that accelerates bearing wear or failure. It doesn't stop at bearing failure; the effect can progress to knocking, rough running, a no-start condition, or loss of engine power while driving.
Toyota has expanded the recall scope in three major waves, progressively covering additional V35A engine production periods.
Toyota announced the first recall in May 2024, and it has since expanded to 2026. The table below explains it at a glance.
1. May 2024: First Recall
Toyota recalled certain 2022–2023 Tundras equipped with the V35A engines on May 29, 2024. The remedy was a free engine assembly.
2. Recall Expands in November 2025
On November 6, 2025, Toyota launched a campaign to recall an additional 2022-2024 Tundras, as well as certain Lexus LX and 2024 GX vehicles. The recall covered 126,691 vehicles cumulatively.
The second wave of the recall is essential because Toyota's investigation found the problem wasn't limited to the production range covered by the 2024 recall. Meanwhile, Toyota continues its investigation.
3. May 2026: Investigation continues: Another 2024 Tundra Expansion
On May 20, 2026, Toyota announced another expansion that covers 43,566 additional 2024 Tundras equipped with the V35A engine.
Toyota's investigation found that engines from later production showed the same wear pattern on the #1 main bearings.
Because engine-machine debris can damage the #1 main bearing and potentially lead to engine knocking or failure, you need to know these warning signs so you can spot them. The fundamental warning signs are
As a Tundra owner, the best way to check whether your vehicle is affected is to use your 17-digit VIN rather than relying on the model and year.
Simple steps to do it:
Toyota's remedy for the Tundra engine recall has evolved from replacing every affected defect to first determining the root cause - no. #1 main bearing wear.
As you can see in the original recall in May 2024. It was a no-cost replacement.
Since then, over 77,000 of the 102,000 vehicles covered by the first recall have been repaired with engines using an improved No. 1 main bearing.
The new remedy Toyota developed (V35A Crank Bearing Inspection) is an accelerometer and diagnostic software to measure the crankshaft resonant response.
The system inspects and identifies abnormal wear of the No. 1 main bearing without tearing the engine apart; if it can't find the fault this way, engine replacement becomes the ultimate solution.
If you notice any engine defect-related symptoms, don't wait for an official recall letter to take action.
Unfortunately, not every Tundra Engine complaint indicates a main bearing recall.
Below is a checklist to help you tell for yourself, even before a professional inspection.
The Tundra V6 engine recall has been a critical and evolving issue. But those who stay informed, watch for early symptoms, and take the right action can keep their vehicle safe and protect their wallets.
