Disadvantages of the GM LKW engine

  • They scold him only for floating idle speeds or glitches of the Start-Stop system.
  • As with all direct injection engines, the intake valves quickly overgrow with soot.
  • You can also find several complaints about lubricant leaks through the oil pressure sensor.
  • There is nothing to say about the operation of the iVLC system yet, it has not yet broken down for anyone.
