Problems:

Oil consumption
The 3UZ-FE engine is known for higher oil consumption as it ages, which can lead to lower oil levels if not monitored regularly.
Timing belt wear
The timing belt on the 3UZ-FE engine requires regular replacement to prevent engine damage; typically, it needs to be replaced every 90,000 to 100,000 miles.
Valve cover gasket leaks
The valve cover gaskets can deteriorate over time, leading to oil leaks which may cause engine misfires or other issues.
Throttle body issues
Build-up of carbon deposits in the throttle body can cause poor engine performance, rough idling, and reduced fuel efficiency.
Cooling system problems
The radiator and water pump can develop leaks or fail, leading to engine overheating if not properly maintained.
Spark plug wear
Worn or fouled spark plugs can lead to misfires, poor fuel economy, and reduced engine performance.
Oxygen sensor failure
Faulty oxygen sensors can cause incorrect air-fuel mixture readings, leading to decreased fuel efficiency and increased emissions.
Mass air flow sensor failure
A failing mass air flow sensor can result in erratic engine performance, stalling, and poor fuel economy.
