From 2009 to 2014, the 2.4-liter General Motors LAF engine was assembled at a facility in the United States and fitted to the GMC Terrain, Chevrolet Equinox, and the Canadian Orlando minivan. This unit’s direct fuel injection system set it apart from its predecessors.
GM Ecotec’s second generation comprises LDK, LHU, LNF, LAF, LEA, LE5, and LE9.

Disadvantages of the GM LAF engine
This power unit’s high oil consumption is its most well-known issue.
Rings can cause oil to burn on runs shorter than 100,000 kilometers.
The engine’s erratic crankcase ventilation system is another flaw.
The timing chain is frequently altered, even over 150,000 kilometers, and it does not have a high resource.
Intake valves rapidly fill with soot, just like in all direct-injection combustion engines.
