Disadvantages of the GM L3A engine
- This is a very reliable motor and there are very few complaints about it on specialized forums.
- It should be noted only high requirements for the quality of the fuel used.
- From bad gasoline, the catalyst is destroyed and its crumbs can get into the cylinders.
- Like all direct injection engines, it suffers from carbon deposits on the intake valves.
- The remaining problems are related to electrical glitches and are being treated with new firmware.
