We did alot research on SUV's and found some challenges with capacity, luxury and a reasonable price. We really liked the Lexus LX 570 but the price 90K+. We looked at the Infiniti QX80 and while it was clearly the most luxurious the exterior was less than desirable. We considered the Cadillac Escalade but found that it had the same capacity and motor as the GMC Yukon Denali at 20K+ dollars more with interior differences. We also considered the Tahoe but when we priced it out with all the options it was the same price as the Denali. All in all the Yukon was the best bang for the buck and quite frankly it just looked better. Our research showed that it was a mix of happiness with owners from 15 and 16 years as these models had alot or recurring issues. We learned that many of the issues were to be resolved in 2017 and decided to lease one. Ours is fully loaded and we really like the technology GM brought to the table. The onstar app and myGMC app are designed well. Our only issue is that sometimes the apple play does't start when connected to the iPhone and we are unsure if it is the USB port or the iPhone cable. It gets great gas mileage as well. We really like the look and the ride and love the fact that is a truck base SUV vs a car base which provides us with more options. If you are looking for a luxury SUV with technology, towing and capacity to seat that is truck base this is your truck.
Raising the gas mileage up to 22 mpg has created major issues. The engine has yet to be refined, the 8 speed trans is also having issues. My son has a 2015 and the kids have broken 2 exterior door handles off, the engine has to be replaced, computer problems (Gremlins). Quality for the price is just not there. I own a 2003 Yukon since new and it has 275k no work has been done on the engine or trans, bottom line is that they are not built the way they used to be. For close to the same price as a Denali, we bought a Mercedes Benz GLS 450, tows what we need, better warranty, built like no other SUV, and much better resale value. Dealer customer service is also second to none. Drop it off once a year for oil change service and inspection, get a loaner with out even asking.
