About the 2018 GMC Canyon

Your 2018 GMC Canyon is from the second-generation Canyon, which covers model years 2015–2022. 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 2018 model year.

Check the model year on your VIN: on a 2018 vehicle the 10th character of the 17-digit VIN is “J”. 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 8 years old, a 2018 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: 2015 GMC Canyon, 2016 GMC Canyon, 2017 GMC Canyon, 2019 GMC Canyon, 2020 GMC Canyon, 2021 GMC Canyon, 2022 GMC Canyon.
