Head gasket failure

This engine can experience head gasket issues, often noticeable through coolant loss, white smoke from the exhaust, or overheating.

Excessive oil consumption

Some owners report excessive oil consumption, which could be due to worn piston rings or valve seals.

Timing chain noise

The timing chain on the 1GR-FE engine may produce noise if it becomes worn or if the tensioner fails, leading to potential timing issues.

Build-up in the throttle body can result in rough idling or stalling, requiring cleaning or replacement.

Crankshaft position sensor failure

A failing crankshaft position sensor can cause the engine to stall or not start, often accompanied by a check engine light.

Fuel injector problems

Dirty or failing fuel injectors can lead to misfires, poor fuel economy, and rough engine performance.

Cooling system leaks

Leaks from the radiator or water pump are common, leading to overheating and potential engine damage if not addressed.
