What warranty comes with a new Yukon XL Denali or SLT?
A new Yukon XL carries GMC’s published new-vehicle warranty, and the same coverage applies to the Denali and the SLT. The basic warranty runs 3 years or 36,000 miles, whichever comes first (GMC, 2026).
GMC’s powertrain coverage is typically 5 years or 60,000 miles, whichever comes first, and other durations are available.
Whichever limit comes first ends the coverage. Mileage matters as much as age, so a buyer who drives a lot reaches the mile limit sooner. For questions about the warranty on the vehicle you pick, call service at (281) 897-6610.
FAQ
How much more Texas sales tax does a Yukon XL Denali’s higher price add?
Texas charges motor vehicle sales tax at 6.25% of the sales price, minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026). A higher sales price means more tax, and a trade-in lowers the amount that gets taxed. The rate stays the same for the Denali and the SLT, so the price is what changes the bill.
What Texas title and registration fees apply when you buy a new Yukon XL?
The annual registration fee for a passenger vehicle or truck of 6,000 pounds or less is $50.75, plus local county fees (Texas Department of Motor Vehicles, 2026). On that fee chart, Harris County adds a local fee of $11.50 (Texas Department of Motor Vehicles, 2026).
What are the EPA fuel economy ratings of the Yukon XL Denali and the SLT?
EPA rates the 2026 Yukon XL with the 6.2-liter gasoline engine at 15 city, 19 highway and 16 combined in rear-wheel drive.
These certified figures match the window sticker, so check the sticker on the vehicle you choose.

In a September 2026 Google review, J A. wrote about buying a 2026 Denali truck: “I recently purchased a 2026 Denali truck, and I couldn’t be more pleased with the level of service I received. My salesperson, Mike Sharaf went above and beyond to make this deal happen. He worked tirelessly to get me into the exact truck I wanted at a price point I was comfortable with. Getting the numbers to line up required stacking a lot of discounts, and Mike didn’t stop until he made it work. A big shoutout to the sales manager and the finance manager as well, the entire team worked hard behind the scenes to finalize the deal and get me out the door happy. Best of all, there were absolutely no high-pressure sales tactics from anyone involved. It was a smooth, honest, and easy buying process from start to finish. If you’re in the market for a new vehicle, ask for Mike Sharaf. Highly recommended!”
