Common Issues for This Vehicle

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.
