The 2UZ-FE engine can suffer from oil sludge buildup if oil changes are not performed regularly, leading to poor engine performance and potential damage.

The timing belt on this engine needs regular replacement according to the manufacturer's schedule, as failure can result in severe engine damage.

Over time, fuel injectors can become clogged or fail, leading to poor fuel economy, misfires, or rough idling.

This engine may experience issues with the cooling system, such as radiator leaks or water pump failures, which can lead to overheating.

The exhaust manifolds on this engine are prone to developing cracks, leading to exhaust leaks and possible engine performance issues.

Spark plugs may wear out or become fouled, causing engine misfires, reduced fuel efficiency, and rough running.

The throttle body can become dirty or malfunction, leading to poor engine response and idle issues.

Over time, vacuum hoses and connections can degrade, causing leaks that affect engine performance and fuel efficiency.

The camshaft position sensor can fail, resulting in engine stalling, misfires, or difficulty starting.

The knock sensor may fail, leading to a loss of power and poor engine performance due to improper ignition timing adjustments.

The 2UZ-FE engine is known for oil sludge buildup, which can clog oil passages and cause engine damage if not addressed.

The 2UZ-FE engine uses a timing belt that requires regular replacement. If the timing belt wears out or breaks, it can cause severe engine damage.

This engine is prone to developing cracks in the exhaust manifold, which can lead to exhaust leaks and reduced engine performance.

Over time, the valve cover gaskets can degrade and cause oil leaks, which can lead to engine misfires and other issues if not repaired.

The Tundra's cooling system can develop leaks or fail, leading to engine overheating and potential head gasket failure.

The mass air flow (MAF) sensor can fail over time, leading to poor engine performance, stalling, and reduced fuel efficiency.

Carbon buildup in the throttle body can cause rough idling, poor acceleration, and engine stalling.

Clogged or failing fuel injectors can lead to poor engine performance, misfires, and reduced fuel economy.

The 2UZ-FE engine can experience knock sensor failures, which can result in the engine running poorly and reduced overall performance.

This engine model is known for oil sludge buildup, especially if oil changes are not done regularly. This can lead to poor engine performance and potential engine damage.

The 2UZ-FE engine uses a timing belt, which can wear out and break if not replaced at recommended intervals. A broken timing belt can cause significant engine damage.

Fuel injectors can become clogged or fail, leading to poor fuel economy, rough idling, and reduced engine performance.

Ignition coils may fail over time, causing misfires, poor acceleration, and reduced fuel efficiency.

The cooling system components, such as the radiator and water pump, can fail or leak, leading to engine overheating and potential damage.

The exhaust manifold on the 2UZ-FE engine can develop cracks over time, leading to exhaust leaks and increased engine noise.

Vacuum hoses and connections can deteriorate, causing vacuum leaks that result in rough idling, stalling, and poor engine performance.

Various sensors (such as oxygen sensors, mass airflow sensors) can fail, leading to check engine light illumination and potential drivability issues.
