Never GM

What you need to know is at 86,000 to 100,000 this vehicle is garbage. They know it and I would drive another. Thank goodness I bought an extended warranty. It is so bad the warranty doesn’t even try to get out of paying. The two fuel injectors died at 60K. The transmission died at 98k and the engine is being replaced at 102k. No, I don’t tow or haul anything. Trash!!! It doesn’t deserve 1 star.

Switched from DENALI XL to YUKON XL

I purchased a new Yukon XL DENALI in 2010 and drove it for 327,000+ miles (original engine) until 4Q2019, when reliability became an issue, but I am still keeping it for a back up. When I looked at the price of a new Yukon XL DENALI, I took a real close look at the Yukon XL and purchased a 2018 with 20,000 miles on it. For sure, this was the right decision; cost was $35,000+ less than a new DENALI XL. For me, the ONLY meaningful difference between the two is that instead of All-Wheel Drive, all the time, I manually switch from 2WD in good weather to 4WD in bad weather; DO NOT USE AUTO, because of wear on transmission. No question: 2 year old YUKON XL with 20,000 miles or less, with warranty still on to 36,000 miles is THE BEST VALUE!

Love It So Far

I love the on board computer for the driver. Coming home from a golf trip right after we got the car, I averaged 29 MPG on the highway for 25 miles. If you drive it smoothly, you will get good gas mileage. All the USB outlets are awesome for traveling with phones and ipads. I am surprised at how small the glove box is for such a large vehicle and I wish the cup holders were bigger. I have read reviews of people complaining about the sluggish gas pedal, but that does not bother me one bit. This is a large SUV, I am not driving it like a sports car.

We bought our 2016 GMC SLT certified a year old, we were aware of the electric/electronic issues the car was known to have, so we purchased a bumper to bumper warranty. We have now had it over 5 years, it has 80k mi and we have driven several road trips including one across the U.S. The 31 gallon gas tank makes road trips a breeze. It is easy to drive, very smooth, powerful, very roomy and comfortable with all the bells and whistles you would want. Its great on gas for the size of vehicle, we love it. We have had a few temporary glitches with the cameras, and radio. But nothing major. We have had to replace the heated seat elements on 2 rows of seats, and a rear taillight, that were thankfully were covered under our extended warranty. The AC compressor just went out around 78k mi and was a 850$ Repair. We previously owned a Land Rover LR3 which had a LOT of problems and was a money pit. Overall we are still very happy with our purchase, there is no other suv out there I would want over it.

Very annoying vibration at 70 mph

Very annoying vibration over the entire vehicle, especially the steering wheel, at 70 mph. The steering wheel would shake my arms. The vehicle was also very poor at absorbing road bumps. Very jolty and jumpy. Strange noise from front transaxle when in auto all wheel drive especially when making 90 degree turns at slow speed. This noise is much worse in four wheel drive. Poor grip from the front wheels in four wheel drive in snow. 35,000 miles. Took it to the dealer for service. They told me it was wear in the tires. They suggested that I replace tires with only 35,000 miles on them. There was no visible wear in the tires. Then I googled the problem and found out there have been numerous complaints dating back to at least 2015 about vibration at 70 mph. GMC is aware of the problem. Dealers have given other customers the run around on the issue and failed to fix it. Nobody at my dealer service department mentioned to me that this was a well known problem with the vehicle. Surely they had heard of this complaint before. Yet they told me to replace these very expensive tires. I read about owners who replaced numerous components in an unsuccessful attempt to stop the vibration. I realized based on my research that this vibration was here to stay. This is unacceptable for an $80,000 vehicle. So I just traded my 15 month old GMC Yukon XL Denali with 35,000 miles. I knew that my service department would not honestly deal with the problem. I read one opinion online that the vibrations occur because the frame was made too stiff in order to increase the strength of the frame for safety reasons. I hate to think of the money I lost. But I wasn't going to keep making $1,000 monthly payments on an SUV that was so unpleasant to drive on the highway and couldn't competently handle the snow. I owned a 2010 Yukon XL Denali before this one. The engine blew up at 100,000 miles and had to be replaced. My patience for GMC just ran out. Never again will I buy a GMC.
