  • And secondly, although the oil consumption is less than its predecessors, there are still enough complaints;
  • Timing chain has a very limited resource, and replacement is difficult and expensive;
  • In the unstable operation of the engine, the failure of one of the ignition coils is often to blame;
  • The sophisticated cooling system for two pumps is not famous for its reliability.
