2003 Chevrolet TrailBlazer TNF 5.3L Vortec V8 from North America
Summary:
Nice family vehicle, if you have the money and time to replace EVERYTHING on it
Faults:
First day I had my "TNF" (The North Face edition) Trailblazer EXT, the plastic above the rear window was buckled upward. As I was driving it back to the dealership the next day to get it replaced, the orange signal on the driver side mirror fell off.
I got home and the truck was running fine until about a month later, when I was driving down a busy road and the steering totally locked up. The power steering pump had went bad and was making this really loud wining noise.
A few months later, I was driving home from work and it sounded like I was driving a jet. I later realized the fan clutch was locked, causing the fan to spin at high speeds. Which made the check engine light come on.
A few months after that, (10/01/09) I was driving home and the car just didn't feel right. I was doing about 45 MPH, then all of a sudden it felt like I accidentally pushed the gear shift into neutral, cause the car wouldn't move. The car started slowing down rapidly. After I got to about 25 MPH, it shifted into second and wouldn't go back into third gear. Later that day I took it to a transmission specialist and he said the whole transmission was completely gone.
My ball joints need to be replaced now. Also my heat/AC does not work due to a bad blower resistor. It caused the blower to stay on after I exited the truck, and it killed my battery about 5 times.
I love this truck cause it's fully loaded with the TNF option, but I've had nothing but problems. My 1996 Ford Thunderbird has ran for over 13 years with no problems besides ball joints. Never again will I buy a GM product.
General Comments:
One thing I love is the power from the 5.3 V8.
Heated seats are great in the winter. Too bad the driver side only works on the back and not the seat itself.
Would you buy another car from this manufacturer? No

It is kind of funny; I have the 03 TNF as well, and have done the full suspension, the transmission, and now I'm doing the blower for the same reasons, and it is not the make of a vehicle anymore, it is the age. I operate a tow unit, and everything with a computer has massive issues compared to the older vehicles built when people cared. I have owned 2 vehicles that made it over 598000 miles with normal maintenance; they were both built in 1972. It's sad to say, tech made everything worse, and manufacturers just don't care anymore.

How come no one else has all these problems you had with your '03?
