Engines from the early years had problems with assembly quality and their components. A typical issue is bearing rotation and engine knocking at a mileage of 100,000 km. Power units after 2000 are more reliable but are very rare to come across. Most complaints on the forum are related to excessive oil consumption and injector clogging. The weak points of the engine also include the ignition system and hydraulic lifters.
