Toyota Tundra Engine Recall Grows Again! Automaker Admits Previous Fix Didn’t Work – Owners Patience Running Thin

A new Toyota Tundra engine recall has been issued the same machining debris issue and the automaker admits the fix hasn’t work, but assures it has fixed many of the failed engines in previously recalled trucks.

The automaker said certain 2024 Toyota Tundra vehicles may contain debris inside the engine that could cause bearing damage, engine knocking, rough running, loss of power and ultimately complete engine failure. The recall for approximately 44,000 2024 trucks expands Toyota’s ongoing problems with the twin-turbocharged V6 powering the current Tundra lineup.

What Toyota Says Is Happening

According to Toyota, debris left behind during the manufacturing process can contaminate the engine assembly and damage internal components over time. Toyota said the issue could lead to engine failure while driving, increasing the risk of a crash.

“Toyota conducted two prior similar recalls,” Toyota stated in the recall notice. “The first was in May 2024, and the second was in November 2025. The engines involved in this new recall were produced using additional controls for removing manufacturing debris. We have found that, even after these additional controls, the remaining debris could be sufficient to cause damage to the #1 main bearing and lead to this issue. Engines produced after those included in this recall were manufactured with an improved #1 main bearing to help resist certain debris that might remain.”

The new recall affects certain 2024 Toyota Tundra trucks equipped with the twin-turbocharged V6 engine. Toyota has not yet released a final remedy but said dealers will inspect and repair affected vehicles free of charge once the fix is finalized.

Owner notification letters are expected to be mailed later this year.

Toyota’s Engine Problems Keep Growing

This latest recall continues a troubling trend for Toyota and the newest-generation Tundra. We have previously covered the many issues surrounding this truck’s engine since it came out including numerous owner complaints involving engine failures, excessive knocking sounds and sudden loss of power tied to the turbocharged V6.

Toyota previously announced a major engine replacement program for earlier Tundra and Lexus LX models after debris from the manufacturing process was linked to catastrophic engine damage.

Many owners reported complete engine failures with relatively low mileage, creating concerns that Toyota’s switch away from the long-running V8 may have introduced unexpected reliability issues. Plus many other known problems with the truck.

The Twin-Turbo V6 Continues To Face Scrutiny

Toyota replaced the old 5.7-liter V8 with a 3.4-liter twin-turbocharged V6 as part of its push for improved fuel economy, emissions compliance and increased power output.

While the engine delivers impressive torque and towing capability, reliability concerns have become a major topic across owner forums, social media and NHTSA complaints.

The issue has become especially damaging for Toyota because the brand has historically built its reputation around long-term dependability and low ownership costs.

Toyota said it has fixed the issue, but questions remain.

“For the recall Toyota announced in May 2024, Toyota has already notified all customers directly about that remedy, and our dealers in the U.S. have already repaired more than 77,000 of the approximately 102,000 covered vehicles.

Toyota urges owners to take their vehicle to their Toyota dealer for the free repair when they are notified that the remedy is available.”

This is meant to reassure customers, however, it has continued to raise questions with consumers. If they haven’t finally a real fix for the problem, what’s to say the replacement engines have been fixed?

Owners Have Been Reporting Problems For Months

Long before Toyota expanded the recall, owners had already been documenting symptoms online including metallic debris in oil, engine knocking, sudden warning lights and complete engine shutdowns.

Some owners reported waiting weeks or months for replacement engines due to limited parts availability and high demand tied to the earlier recall campaign.

The growing number of recalls and investigations has also fueled debate about whether modern turbocharged downsized engines can maintain the same long-term durability as older naturally aspirated V8 engines under heavy towing and hauling conditions.

What Tundra Owners Should Do Next

Toyota says owners can check whether their truck is included in the recall by entering their VIN on Toyota’s recall website or through NHTSA.gov.

Until a final remedy is announced, affected owners should monitor their trucks for unusual engine noises, warning lights or rough running conditions and contact a dealer if symptoms appear.

For Toyota, the bigger problem may be rebuilding owner confidence as recalls tied to the newest Tundra continue to pile up.
