Problems:

Oil leaks

The 1GR-FE engine is known to develop oil leaks over time, particularly around the valve cover gaskets and the front timing cover.

Head gasket failure

V6 engines, including the 1GR-FE, can sometimes suffer from head gasket issues, leading to coolant leaks and overheating.

Timing chain noise

The timing chain and its associated components can wear out, leading to rattling noises, especially during cold starts.

Carbon build-up

Due to the engine's design, carbon build-up on the intake valves can occur, which can affect performance and fuel economy.

Cooling system issues

Radiator and water pump failures are relatively common, potentially leading to overheating problems.

Fuel injector problems

The fuel injectors can become clogged or fail, causing rough idling, misfires, and decreased performance.

Spark plug and ignition coil wear

Over time, spark plugs and ignition coils may wear out, leading to misfires and reduced fuel efficiency.

Throttle body issues

The throttle body can become dirty or fail, leading to erratic idling and throttle response issues.

Sensor failures

Problems with sensors such as the Mass Air Flow (MAF) sensor, Oxygen (O2) sensors, and Crankshaft Position sensors can cause various engine performance issues.

Exhaust manifold cracks

The exhaust manifolds on the 1GR-FE engine can crack over time, leading to exhaust leaks and noise.
