We cover three LaCrosse generations. The first (2005 to 2009) uses 3.8- and 3.6-liter V6 engines. The second (2010 to 2016) offers a 2.4-liter with eAssist mild hybrid and a 3.6 V6. The third (2017 to 2019) uses a 3.6 V6 with an 8- or 9-speed automatic.


Your 2016 Buick LaCrosse is from the second-generation LaCrosse, which covers model years 2010–2016. It is the last model year of this generation and includes the running changes made during production, which is why a manual for the exact year matters.
Check the model year on your VIN: on a 2016 vehicle the 10th character of the 17-digit VIN is “G”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 10 years old, a 2016 vehicle often needs work on the cooling system, timing components, suspension bushings, motor mounts and corroded electrical connectors, all jobs where the exact factory procedure and torque values save time.
Same generation: 2010 Buick LaCrosse, 2011 Buick LaCrosse, 2012 Buick LaCrosse, 2013 Buick LaCrosse, 2014 Buick LaCrosse, 2015 Buick LaCrosse.
