My 2005 Chevrolet Trailblazer has been nothing but a problem. Since I've owned it for 3 years I've paid over 4k in repairs. I just had my exhaust manifold replaced in August of 2013 do to it cracking. Now in September of 2014 it has cracked again. My stereo has a whining noise that comes through the speakers daily. My headlight had a short in the wiring and has to be replaced every 3 months. I've had the brakes replaced twice in 3 years. I've had bearing replaced twice. This vehicle has been nothing but problems.

I have a 2005 Trailblazer as well and have had nothing but problems with it. The first was when the 4WD knob broke off. Then the fuel gauge stopped working. I also have a wiring problem that causes interference between the speakers and the accelerator (I hear a high pitched whizzing noise when I press on the accelerator). In the fall of 2009 the speedometer started malfunctioning like the problems that other posters have had. In the past year the oil gauge has now stopped working. The most recent defect in this glorified hunk of metal is a crack in the exhaust manifold. I will never purchase another GM product due to the number of problems and lack of customer support from the company. I cannot say that I am surprised that the company has gone bankrupt.
