From 2011 to 2017, the US plant produced a 2.4-liter General Motors LEA engine, which was fitted to the Canadian versions of the Verano sedan, Equinox crossover, and Chevrolet Orlando minivan. This power unit is referred to by its LUK index as part of the eAssist hybrid installation.

Disadvantages of the GM LEA engine
Due to the occurrence of rings, the majority of complaints regarding this unit are related to oil consumption.
After an updated piston was installed in 2014, the issue became less frequent.
A clogged crankcase ventilation system may also contribute to oil burning.
The timing chain is not very resource-efficient and frequently requires a 150,000 km replacement.
The intake valves are covered in soot, just like in all direct injection engines.
