One problem related to brake disc pads has been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
My front brakes had to be replaced after 24,000 miles. I have had other SUV and this seems like inferior products are being used. The dealer had to turn rotors and also replace a torsion bar. I do not drive this vehicle for work, I have a company car and the brakes were replaced on it at almost 45,000 miles.
