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.

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.…
