Disadvantages of the GM LYX engine

  • This is a completely reliable turbo engine, but it is demanding on the quality of fuel and lubricants.
  • Attempts to save money often lead to detonation and a burst piston septum.
  • On specialized forums, you can find many complaints about the inadequate operation of the start-stop system.
  • As with all direct injection engines, the intake valves are overgrown with soot.
  • The cause of many problems is a pipe disconnected from the throttle assembly.
