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.
