Disadvantages of the QR25DD engine

  • Most complaints about the rapid contamination of injectors or the failure of the high pressure fuel pump;
  • Due to the accelerated carbon formation, rings lie down and the oil burn begins;
  • There are cases of destruction of the catalyst and stretching of the timing chain even up to 100,000 km;
  • The engine does not like low temperatures and in cold winters you can suffer with it;
  • Minor problems include thermostat glitches and leaks from under the valve cover.
