1. The 3.5L V6 Engine (2GR-FE) failed due to the subsequent loss of lubrication caused by the rupture of the Oil Cooler Pipe (Rubber component), a manufacturing defect known under TSB T-SB-0201-11 (ZE2 Program). The failed engine is currently available for inspection by request at the independent service center before it is disposed of. 2. The defect causes a sudden and severe loss of engine oil. This creates a high probability of the engine seizing (losing all power) while driving at highway speeds, resulting in a complete loss of propulsion and placing occupants at severe risk of collision. 3. The failure was confirmed, not reproduced. The vehicle was initially diagnosed with misfire codes (P0300, P0301). New spark plugs and ignition coils were installed in an attempt to resolve the issue. As the misfire persisted, the mechanic performed a compression test, confirming catastrophic zero compression failure in cylinders 1 and 2. Professional diagnostics then revealed critical codes: P1603 (ECM Malfunction), P1604 (Startability Malfunction), and P1605 (Rough Idling). These codes confirm a severe internal engine issue, consistent with permanent damage sustained during the oil loss event caused by the ZE2 pipe defect in July 2024. 4. No, not physically inspected by the manufacturer. The manufacturer (Toyota Executive Office Case Manager) was provided with certified documentation of the failure, including the photo of the faulty pipe, maintenance records during our ownership, and the dealership purchase statement for the replacement part. Toyota refused to authorize a physical diagnostic inspection of the failed engine at a dealership before denying goodwill assistance. 5.Yes. The initial lubrication loss event on July 4, 2024, was preceded by a message displayed on the dashboard (followed by a second failure event in October 2025 indicated by a flashing Check Engine light and the Traction Control light).
