Disadvantages of the QR25DER engine

  • This power unit is afraid of overheating and the cylinder head gasket breaks through it regularly;
  • Violation of the temperature regime quickly leads to the occurrence of rings and oil burn;
  • The use of low-quality fuel greatly reduces the life of lambda probes and catalyst;
  • A short-lived timing chain often stretches and needs to be replaced before 150,000 km;
  • It is also worth noting that some spare parts for this motor are rare and very expensive.
