“Back up camera is terrible. My 2017 CTS is terrific. Location of setting driver 1 & 2 memory bad. Response to phone calling needs improving. No route options on navigation. The only changes made in 4 years was the price. I have owned a 08, 12, 16 and a 2020.”
2020 GMC Yukon: What's New, Specs & Features
Last updated August 4, 2026
The 2020 GMC Yukon is a carryover with no major changes from 2019. It is the final year of this generation before the fully redesigned 2021 Yukon.
About the 2020 GMC Yukon
4th generation (2015-2020), final year before the all-new 2021 redesign
GMC positions the Yukon as a premium full-size SUV for buyers who need real family space, strong V8 towing ability, and a more upscale look and feel than a mainstream large SUV. The model’s core appeal is simple: big passenger room, serious cargo and trailer capability, and a trim walk that starts practical and ends genuinely luxurious in Denali form. It is the GMC version of a traditional body-on-frame family hauler with a richer cabin and more polished image.
The SLE covers the essentials with a 5.3-liter V8, an 8-inch touchscreen, smartphone integration, and three-zone climate control. SLT models focus more on leather-trimmed comfort, while Denali pairs a 6.2-liter V8 and 10-speed automatic with an adaptive suspension, head-up display, and wireless phone charging.

4.2
2020 GMC Yukon
(92 reviews)
“I think this vehicle is a great value and so far has quality workmanship. Just get the price right to offset the lack of support with a quality warranty.”
“The Yukon XL does not disappoint, the information (marketing) provided by the manufacturer has been dead on in regards to the vehicles capabilities so far. I know I can rely on this vehicle to get the job done while getting me and my family where we need now, and for years to come.”
