The Enclave is Buick's three-row SUV. The first generation (2008 to 2017) uses a 3.6-liter direct-injection V6 with a 6-speed automatic. The second generation (from 2018) keeps a 3.6 V6 and adds a 9-speed automatic, with front- or all-wheel drive.


The 2018 Buick Enclave belongs to the second-generation Enclave, built for model years 2018–2024. It is the first model year of this generation: the platform, wiring and many procedures changed compared with the previous model, so a manual for an earlier year will not match it.
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: 2019 Buick Enclave, 2020 Buick Enclave, 2021 Buick Enclave, 2022 Buick Enclave, 2023 Buick Enclave, 2024 Buick Enclave.
