      I absolutely love my truck. Comfort is better than our Cadillac and it looks awsome. Luxury interior and amazing in the snow.

      I have decided that this will be the first and final General Motors (GM) product that I will purchase. The air conditioning failed at 60,000 miles due to a problem with the condenser. At 65,000 miles, I had to replace the transmission because it was causing very rough shifts between gears 1-2 and 2-3. Unfortunately, at 120,000 miles, the transmission is once again exhibiting the same issue it had before it was replaced. Additionally, I was unlucky enough to have a truck that experiences paint peeling on nearly every body panel. This is especially prominent in large sections near the windows and rear doors. Needless to say, I will not be making this mistake again.

      Terrible vehicle. They sold them know transmission was bad. I’ve put new transmission in 2021. And now it’s going out. Will be third transmission jn 142,000 miles
