This engine uses a timing belt, which can wear out and potentially break if not replaced at recommended intervals, leading to significant engine damage.
Excessive oil consumption
Some owners report higher-than-normal oil consumption, which may be due to worn piston rings or valve seals.

Issues with oxygen sensors and mass airflow sensors can occur, leading to poor engine performance and reduced fuel efficiency.
Cooling system problems
Radiator or water pump failures can lead to overheating, potentially causing severe engine damage.
Crankshaft position sensor failure
A faulty crankshaft position sensor can cause the engine to stall or fail to start.
Exhaust manifold cracks
