Disadvantages of the GW6Z30 engine

  • In the first year of production, the motor had a lot of problems, but most have already been fixed.
  • Now the main complaints on the network are related to uneven response to the gas pedal.
  • A number of flashes have already been released, but power failures still occur.
  • The combined injection system saves the engine from the formation of carbon deposits on the valves.
