Since 2017, the American plant has been producing the General Motors LFY 3.6-liter V6 engine, which powers the full-size crossover Chevrolet Traverse and the comparable Buick Enclave. The motor’s new intake manifold and start-stop system set it apart from its predecessors.
L3B, LP9, LF1, LFX, LFY, LGX, LLT, and LY7 are high feature engine families.

Disadvantages of the GM LFY engine
Although this engine is incredibly dependable, it needs to have its oil changed as frequently as possible.
The timing chain tensioners will not last long if the lubricant is changed in accordance with the regulations.
It has carbon buildup on the intake valves, just like all direct injection units.
This series’ engines are all terrified of overheating, and ironically, radiators frequently leak.
Additionally, this motor was affected by a larger recall campaign for the High Feature engine.
