Import watchouts

• Inspect the turbocharger oil supply lines and intercooler piping for signs of seepage or brittleness, as the 2UZ-FSA’s high-pressure oil system can develop leaks at the turbo manifold connections, leading to oil consumption and potential turbo failure if not addressed.
• Check the rear subframe and rear wheel arches for surface rust or undercoating damage, particularly on vehicles with high mileage or from regions with heavy road salt usage, as the rear suspension mounting points are prone to corrosion that can compromise structural integrity.
• Verify the operation of the Direct-Shift 10-speed transmission by monitoring for any hesitation or shudder during the 1-2 shift at low speeds, as early software glitches or fluid degradation can cause engagement issues that require specific T-IV fluid and transmission control module recalibration.
