We cover the Regal from 2000 to 2020. Early cars use the 3.8-liter V6, with a supercharged version in the GS. The 2011 to 2017 Regal uses 2.4-liter and 2.0-liter turbo engines. The 2018 to 2020 Regal Sportback and TourX use a 2.0 turbo with an 8- or 9-speed automatic and available AWD.


The 2017 Buick Regal belongs to the fifth-generation Regal, built for model years 2011–2017. 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 2017 vehicle the 10th character of the 17-digit VIN is “H”. 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 9 years old, a 2017 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: 2011 Buick Regal, 2012 Buick Regal, 2013 Buick Regal, 2014 Buick Regal, 2015 Buick Regal, 2016 Buick Regal.
