Ordered (as soon as the order bank opened) and took possession of my 2021 GMC Yukon SLT on July 30th, 2020. I love this vehicle. Now, that said, it hasn't been trouble free and now has 34K on the odometer. Besides the recalls, (re-programming mostly) I did have a chip go bad that shut down half the fuel injectors and left me on the side of the road. Fortunately, it was close to home, so not a big deal. It did temporarily test my faith in it, since it was a early production vehicle, but smooth sailing since. I am 6 foot, 5 inches and this vehicle is the most comfortable to drive, and I had 5 Tahoe's in a row before this ('97, '99, '02, '07 & '15). Now that I'm in a Yukon, I won't be going back to a Tahoe. It's the little things like all LED everything on the Yukon, but the Tahoe is still using bulbs in taillights and turn signals???? How is that possible on a $60-$70K vehicle? Plus, the GMC exterior front end styling on the 2021 is just so much better than the Tahoe, IMHO. The exhaust note is awesome, for a single, and man does that transmission shift and perform so smooth.....and very responsive. It makes it seem like you have more horsepower than you do.
Anyway, just glad I got mine when I did. Can't imagine waiting 12-16 weeks to get one now....got mine in 5.5 weeks back in 2020.
