2015 Yukon Denali XL 8-Speed & 6.2L. Purchased roughly 20 months ago CPO w/ 23K miles.
Currently sitting at 71K miles (mostly highway miles for work travel) and it’s been a great commuter, work/family vehicle. Got a decent local dealership for service, performed a few TSB’s no questions asked, am working on getting close to a first name basis with my go to service adviser though I haven’t had to go enough to solidify this (Previous Chevrolet & Cadillac dealership service experience has proven this to have a positive impact when needing warranty/service “favors” and at minimum honest straight forward communication. I suggest any vehicle owner strive to establish this type of relationship at their dealership for service no matter what brand of vehicle.). They even went above and beyond on a simple warranty claim, zero buffeting/booming. Although I’ve accepted the fact due to family size and vehicle capability needs I don’t make vehicle decisions based on MPG (honesty never have). Thoroughly impressed with my best of 26.7 MPG and of 22+ on 1 hr. or longer road trips and 14-17 MPG average day to day.
Despite all the threads you find on this forum that often consist of members who only signed up to make one single post/thread topic about their vehicle “review” and their unfortunate experience. Those type of vehicle experiences can be found across any vehicle make or model. There are quality 2015’s with dare I say MRC, 22” wheels, and an 8 speed transmission that ride great, perform as expected, and serve their purpose.
This forum has more than enough experienced members, repeat owners, and applicable first hand experience to provide you with the right tools of what to look for, what boxes to check before purchasing etc. Demand an extended 24 hr. test drive, get to know the vehicle as much as you can before pulling the trigger, and make an educated decision. If everything checks out and goes well you’ll be fine with a 2015... I don’t regret my decision one bit.
Good Luck in your search and purchase of your next vehicle.
