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.

Your 2019 Buick Regal is from the sixth-generation Regal, which covers model years 2018–2020. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2019 model year.
Check the model year on your VIN: on a 2019 vehicle the 10th character of the 17-digit VIN is “K”. 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 7 years old, a 2019 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
Same generation: 2018 Buick Regal, 2020 Buick Regal.
