NHTSA Complaint #11705964 — 2024 TOYOTA TUNDRA

I am submitting a safety defect concern regarding Toyota’s V35A 3.4L twin-turbo V6 manufacturing defect involving machining debris contaminating crankshaft main bearings. Toyota initiated a safety recall in May 2024 for MY 2022–2023 Toyota Tundra and Lexus LX vehicles, citing debris left in the engine during manufacturing that can lead to bearing failure, engine failure, loss of motive power, and increased crash risk. In November 2025, Toyota expanded this recall to include MY 2022–2024 Toyota Tundra, MY 2022–2024 Lexus LX, and MY 2024 Lexus GX vehicles, citing the same defect mechanism. Despite this expansion, Toyota has excluded i-FORCE MAX hybrid vehicles from the recall population. My vehicle is a 2024 Toyota Tundra i-FORCE MAX, VIN [XXX] , build date 02/2024, with 3,667 miles. It uses the same V35A 3.4L twin-turbo engine architecture and manufacturing process implicated in the recall. The presence of a hybrid electric motor does not eliminate the underlying defect mechanism (engine-internal debris contamination) nor the risk of sudden engine failure, loss of power under load, or unsafe drivability conditions. Excluding hybrid vehicles appears inconsistent with the stated defect cause and may result in similarly affected vehicles not being inspected, remedied, or disclosed to owners. I respectfully request that NHTSA evaluate whether Toyota’s exclusion of i-FORCE MAX vehicles is technically justified given the defect mechanism described, and whether additional investigation or recall expansion is warranted. At this time, my vehicle has not exhibited failure symptoms; however, this is a latent manufacturing defect with potential safety consequences.
