Only the tenth generation of the Chevrolet Impala sedan and the eighth generation of the Malibu were equipped with the 2.5-liter General Motors LKW gasoline engine, which was manufactured in the US between 2013 and 2019. The exclusive iVLC valve lift adjustment system set this unit apart.
LSY, LTG, LCV, and LKW are members of the third generation of GM Ecotec.

Disadvantages of the GM LKW engine
They only reprimand him for Start-Stop system errors or floating idle speeds.
The intake valves rapidly fill with soot, as is the case with all direct injection engines.
Additionally, the oil pressure sensor has been the subject of numerous complaints regarding lubricant leaks.
The iVLC system has not yet malfunctioned for anyone, so there is nothing to say about how it operates.
