Love this vehicle - plenty of room for our family of 6. Other than routine maintenance (oil changes, brakes, tires) our only service issue has been replacing battery and front wheel bearings at 6 year mark. No complaints here :) This has been a very versitile and reliable vehicle for us.
I was looking for an SUV that was less than $50,000 and I was looking at the Tahoe and TrailBlazer. I thought I would've got better gas mileage than if I were driving a Tahoe but not true. My wife's '03 Tahoe gets better mileage than my '06 TrailBlazer This car has to go out of my garage and back onto the car lot.
Had a serious accident. I was hit on driver's side front tire full length of drivers side. $12000 in damage, but the good news is no injuries. No jarring inside. Nobody got a scrape or scratch or even a bruise, This thing totally protected us and there was no damage inside. I would definetly buy another one. They are fixing this one, but it gave us total protection in the accident. You can't beat that, and the damage was all cosmetic. The other car was totalled.
Bought a used 2004 back in July '05. No problems over the last 4 months and 4K miles. Great gas mileage for a large SUV. Averaged 13 mpg while towing the largest U-haul trailer, and 15-16 around town. The same mileage as the smaller 2003 Ford Explorer we had. My A/C comes on strong and cold fairly quickly and access to the back seat can be made easier by tilting the entire middle seat forward instead of just tilting the seatback.
We bought our 2006 Trailblazer approximately 3 years ago, so the vehicle would have been 3 years old. Since that time we have had to replace the switch for the windows because they quit working. Now the motor acts like it will give out anytime. The heater fan at a cost of $400, the fuel gauge quit, which is quite the production because they have to drop the whole fuel tank. Chevrolet does have a recall since they have had this problem often so they will reimburse you for half. My check engine light comes on every so often along with the "skid" light. When they decide to they don't go off for awhile. Now it is rusting on the doors.
