Disadvantages of the GM L3A engine
There aren’t many complaints about this motor on specialized forums, and it is incredibly dependable.
Only strict standards for the fuel’s quality should be mentioned.
Bad gasoline destroys the catalyst and allows its crumbs to enter the cylinders.
It has carbon buildup on the intake valves, just like all direct injection engines.
New firmware is being used to address the remaining issues, which are caused by electrical glitches.
