The stereo, though clear and loud, has intermittent malfunctions.
The leather upholstery has begun to wear-through on the driver side.
The Avalanche is sluggish off-the-line, but after about 25-30 mph is pretty responsive.
The towing performance is overrated. I pull a 16' trailer with less than 1000 lbs. on it and wish there was some more torque.
We own a 2003, love it and pull and ramp a 5,000 lb boat on a 2,000 lb trailer with no problem. You must have something wrong! A malfunction maybe!
