Top Risk Areas
The systems that tend to fail first on the 2021 Toyota Tundra, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The secondary air injection pump and associated valves are known to fail, often due to moisture intrusion or valve sticking. This triggers check engine lights and can lead to rough idling or reduced power.
The exhaust manifold gaskets on the 5.7L engine are prone to leaking, especially over time. This manifests as a ticking noise that's louder on cold starts and diminishes as the engine warms up, indicating exhaust gases escaping.
