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.
