      Excellent Machine, Safety Features are Excessive

      by BenInKentucky on 7/14/2026 10:14:58 PM

      First, get the diesel. This is our 3rd diesel Yukon and they are amazing. Great mileage, great resale value, plenty of horse power, and the range for one tank of fuel can be very convenient on long road trips. The extra room in the XL model is also convenient for luggage if you have a large family and enjoy the ability to see out the back windows. The 10 speed transmission is smooth and it will glide down the interstate at any speed with ease at very low engine RPM. The only real downside to this vehicle are the overbearing safety features. If I look over at the navigation screen it vibrates the seat and tells me I am distracted. The auto-cruise (self-driving) feature will randomly hit the breaks in the middle of the highway. The backup camera will slam on the breaks if it sees any movement behind the vehicle even if it is way out of range. The back hatch opens automatically if you walk past it with the key in your pocket. If I lean too far on to the center console it will vibrate the seat and tell me I am distracted. We use this vehicle on the farm and there is no way to disable the seat belt alarm. We spent about an hour going through all of the settings and were able to disable most of the annoying features. I find putting a business card in front of the camera that looks at my face cures many of these frustrations and I may opt for a more permanent piece of black electrical tape that will blend in seamlessly. The auto stop feature is also frustrating but like the EPA gas cans I believe most of America is dealing with this frustration and it is not limited to this vehicle. Overall, we love the vehicle and will buy another one.

      No Problems Yet

      by CoachTroy72 on 6/17/2026 11:26:04 PM

      I got my 26 Yukon Denali SUV with 3 miles on it. Got to 308 and had engine knock. Took it to Classic GMC, they had it a week. Flushed out the engine debris, no knocking. Also they changed the oil. Not from 0-20w to 40w, but just changed it with the same OEM AC Delco standard Dexos, no more knocking. Now at 1238 miles havent had any issues. Actually getting 22.3 MPG! For a truck that is 17 city 20 Hwy..

      Love everything about my Elevation, except…

      by Carol Ann on 6/3/2026 5:57:12 PM

      This truck has excellent get up and go power, great traction control and steering, with an impressive turning radius, love the large dash display screen, sleek design inside and out, and the suspension makes for comfortable long highway and city driving. Surrounded in cool luxury, state of the art sound system while feeling like a VIP in my classy black FBI looking whip.
