Disadvantages of the ES9J4S engine

  • Many engine problems due to the use of low-quality fuel and oil;
  • Spark plugs fail pretty quickly, followed by ignition coils;
  • Lambda probes are afraid of bad gasoline, and replacing all four will be expensive;
  • Non-original oil often oozes from numerous gaskets and seals;
  • Owners often delay replacing the timing belt, which is fraught with a major overhaul.
