“Major complaint about the vehicle is that the side windows are too small and hard to see out of.”
2015 Buick LaCrosse: What's New, Specs & Features
Last updated August 13, 2026
The biggest change for the 2015 Buick LaCrosse is the new 1SV trim, which puts the 304-hp V6 into a simpler entry model. Otherwise, this is a light-update year following the LaCrosse’s 2014 refresh.
About the 2015 Buick LaCrosse
2nd generation (2010-2016), second year after the 2014 refresh.
Buick positions the LaCrosse as a quiet, comfort-first full-size sedan with near-luxury manners. The big selling points are its hushed cabin, roomy seating, easy highway ride, and a step-up interior feel without trying to be a sport sedan. Within its class, it stands out for noise isolation, relaxed long-trip comfort, available AWD, and a choice between the fuel-saving eAssist setup and the stronger V6.
The 2015 LaCrosse is a quiet, roomy sedan focused on comfort and relaxed driving. The 1SV pairs the V6 with an 8-inch touchscreen and a rearview camera, while Premium I adds heated and ventilated front seats and Bose audio. Premium II tops the range with navigation and an adjustable suspension with a Sport mode.
