Problems:

Oil leaks
The 2UZ-FE engine is known for developing oil leaks over time, particularly from the valve cover gaskets and the front crankshaft seal.
Timing belt wear
The 2UZ-FE engine uses a timing belt which requires regular replacement. If neglected, it can lead to severe engine damage.
Exhaust manifold cracks
The V-shaped configuration can sometimes lead to cracks in the exhaust manifold, causing exhaust leaks and reduced engine performance.
Fuel injector issues
Over time, the fuel injectors can become clogged or fail, leading to poor fuel economy and engine misfires.
Spark plug wear
As with most high-mileage engines, the spark plugs can wear out and need regular replacement to maintain engine performance.
Throttle body carbon buildup
Carbon deposits can accumulate in the throttle body, causing poor acceleration and idle issues.
Coolant leaks
Coolant leaks from the radiator, water pump, or hoses can be common and should be addressed to prevent overheating.
Mass air flow sensor failure
The MAF sensor can become dirty or fail, leading to incorrect air-fuel mixture and reduced engine performance.
