I've had around 28 cars and suv's and this one is my favorite (the only one that comes close was my 2002 Tahoe LT). I purchased my TB with 72,000 miles on it 3 years ago and now have 115,000 on it and have only done normal things (tune up, tires, brakes, fluids, belts, lights). The only major thing that I had to do was the flex plate on the transmission was cracked.
My TB is used every day for work and I do a lot of city driving and it turns better then most sub-compact cars do and can fit in most if not all parking garages in Philly, New York, Washington DC, and so on. The ride is great, the truck is easy to work on and tows my pop up with ease couldn't be happier with this pack-mule.
My parents have been GM/Chevy people ever since I can remember. I think their first was a 1962 Impala Station Wagon. Anyway, I was with them when they purchased their Trailblazer. What [non-permissible content removed]! All the same issues as everyone else has been stating. Stalling at lights & pulling into and out of the driveway and intermittent rough idle and high rapid idle for no reason at at 32,000 miles. 40,000 miles brought about incorrect inside/outside temperature readings & inability use climate control which was supposedly unrepairable. Seatbelts that don't release & just keep getting tighter and tighter ever since purchase and they can't seem to repair it or didn't want to.
Our 2002 Chevy Trailblazer is just about to hit 300,000 Miles on the odometer. We have done regular maintenance every 3,000 miles. We have had only one minor issue, which was a coil pack. Everything else about this vehicle has been perfect. Ours is our daily driver and is garage kept. I tend to do around 100 miles of driving on it each day. It is an amazing truck.
The only good about the trailblazer was the space I had the third row seat for the kids !!! Bought it with only 16,000 miles and had some problems soon as we paid it off the tranny went at only 58,000 miles didn't fix it got rid of it end of story!!!!!
