Most frequent / serious themes first; amber labels mark year gates.
Care must be taken when tightening bolts and spark plugs, as the cylinder head cracks easily.
Like all direct injection engines, this motor cokes up quite quickly.
Closer to 150,000 km, noise from the timing chain often appears, indicating its stretching.
Due to contamination of the throttle body, engine idle speed fluctuates.
After 200,000 km, almost all owners experience oil consumption.
This engine is quite reliable and has no serious design flaws, but many owners complain about oil consumption, sometimes even from low mileage. Selecting the right oil, decarbonization, or overhaul may help eliminate oil consumption.
According to the service schedule, the timing chain is designed to last the engine's lifetime, but in reality it often needs replacement before 200,000 km, usually together with the VVT phaser.
Forum reports describe cases of severe power loss in hot weather. The culprit is often the intake air temperature sensor, which is integrated into the MAF sensor.
The aluminum cylinder head is quite delicate, afraid of both overheating and excessive force when tightening bolts or spark plugs. Be extremely careful, or you may need a new cylinder head due to cracking.
Minor problems include idle fluctuations due to throttle body contamination, constant squealing of the accessory belt, and knocking noises from valves requiring adjustment.
