Common Issues for This Vehicle

Oil leaks

The 2UZ-FE engine is known for developing oil leaks, particularly from the valve cover gaskets and the front crankshaft seal.

Timing belt wear

The timing belt in the 2UZ-FE engine should be replaced regularly (typically every 90,000 to 100,000 miles) to prevent engine damage.

Excessive oil consumption

Some users have reported issues with the engine consuming more oil than expected, which could be due to worn piston rings or valve seals.

Cracked exhaust manifold

The exhaust manifolds on the 2UZ-FE engine can develop cracks over time, causing exhaust leaks and noise.

Throttle body issues

Build-up in the throttle body can lead to poor idling and acceleration problems, requiring cleaning or replacement.

Cooling system problems

Radiator and water pump failures have been reported, leading to engine overheating if not addressed promptly.

Spark plug wear

The 2UZ-FE engine can suffer from premature spark plug wear, necessitating more frequent changes.

Fuel injector failures

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

Knock sensor failure

Knock sensors can fail, causing the engine to run inefficiently and potentially triggering the check engine light.
