One problem related to wiring has been reported for the 2017 GMC Yukon. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2017 GMC Yukon based on all problems reported for the 2017 Yukon.
Transmission went out at 88k miles. My sister in law also has a 2017 bought from another state and it went out at 79k miles a week after mine. Passenger side tail light works if you push on it then randomly goes out (wiring/electrical issue). Of course the drivers side tail light is the only one on recall. Cruise control set itself at over 100mph and rapidly accelerated until I hit the brakes. I received a recall for the breaking system specifically for my VIN number that needs to be fixed now that my transmission is complete.
