Disadvantages of the GM LIH engine
The Start-Stop system’s noises, vibrations, and glitches are criticized on specialized forums.
It has carbon buildup on the intake valves, just like all direct injection engines.
You must replace the lubricant as frequently as you can because it has a timing belt in an oil bath.
There are still a lot of complaints regarding how the EVAP fuel vapor recovery system operates.
