📖Buick LaCrosse II facelift: revised luxury interior demanding diligent V6 oil and transmission care

Buick LaCrosse II (facelift 2014) (2014-2016)

The 2014 facelift revitalised the Buick LaCrosse II with restyled front and rear LED light signatures, active front grille shutters, a redesigned centre stack with fewer buttons, and an 8-inch reconfigurable instrument cluster. With the Ultra Luxury interior package, it offered Semi-Aniline leather and genuine Tamo wood trim. Maintaining this premium saloon requires proactive Buick LaCrosse maintenance, targeting powertrain fluids and electronic features.

The mechanical heart is the refined 304 hp 3.6-litre LFX V6, which integrated the exhaust manifolds into the cylinder heads to reduce weight and improve warm-up times. Power is sent through the improved 6T70 6-speed automatic, with available intelligent AWD. While the LFX resolved early timing chain stretching issues, the engine cooling system and direct fuel injectors still require disciplined upkeep.
