Used GMC Yukon — common problems and service

Engine problems are the most common complaint area for the 2019-2026 Yukon, concentrated heavily in the 2021-2023 model years, with 2021 having 157 engine complaints, 2022 having 105, and 2023 having 159. The sources do not specify exact failure modes, but they state that engine failures and transmission problems are frequently reported in 2021-2023 models, and the 2021 model year carries crash- and fire-related severity flags. Before buying a 2021-2023 Yukon, check the vehicle's complaint history and recall completion status.

Powertrain and transmission complaints are a leading problem area for nearly every year in the 2019-2026 range, with the highest counts in 2021-2023, including 62 powertrain complaints for 2021, 31 for 2022, and 46 for 2023. The sources do not list specific symptoms such as hesitation or slipping, but they state transmission problems are frequently reported in the 2021-2023 generation. When inspecting a used 2021-2023 Yukon, verify that any powertrain-related recalls or service campaigns have been performed.

Electrical system complaints recur throughout the 2019-2025 data and are materially higher on 2022-2023 models than on earlier 2019-2020 models, with the source listing 34 electrical-system complaints for 2022 and 40 for 2023. The source does not identify whether the failures involve infotainment, sensors, battery/charging, or other systems. The main consequence is elevated complaint volume, so a pre-purchase electrical system check is advisable for fifth-generation Yukons.
