Disadvantages of the GM LIH engine
- On specialized forums, it is scolded for noises, vibrations and glitches of the Start-Stop system.
- Like all direct injection engines, it suffers from carbon deposits on the intake valves.
- Since it has a timing belt in an oil bath, you need to change the lubricant as often as possible.
- You can still find many complaints about the operation of the EVAP fuel vapor recovery system.
