I have owned my Tahoe for about 2 years. I absolutely LOVE it. The previous owner really rode it hard but she is still truckin'. I had to put a rebuilt trany in her when I bought her but I've had zero problems outside of the normal wear and tear. I just had a baby and I call her my rad mommy wagon. You won't catch me behind the wheel of a minivan. Her interior trim rattles inside at highway speeds and the windshield pops everytime I shut the door. The rear wiper desides when it wants to work and the paint on the top center of the hood is peeling. The CD player will not play when the truck is cold. All very minor problems that are easily corrected.
The power in the pedal is awesome!! My model has the tailgate instead of the more popular rear doors. Believe it or not I like this arrangement better.
Gas mileage is mediocre but expected. The current gas prices are hurting though but that's not the truck's fault.
