Common Issues for This Vehicle
Oil leaks
The 2UZ-FE engine is known for developing oil leaks, particularly from the valve cover gaskets and oil pan gaskets over time.
Timing belt wear
This engine uses a timing belt that requires periodic replacement, typically around 90,000 miles. Failure to do so can result in severe engine damage.
Excessive oil consumption
Some owners report that the engine consumes more oil than expected, which can be due to worn piston rings or valve seals.
Coolant leaks
Radiator and water pump failures can lead to coolant leaks, which, if not addressed, can cause the engine to overheat.
Misfires
Ignition coil packs can fail, leading to engine misfires. This is often accompanied by a check engine light and rough running conditions.
Carbon buildup
Over time, carbon can build up on the intake valves and combustion chambers, leading to reduced engine performance and fuel efficiency.
