One problem related to brake disc rotor has been reported for the 2003 Cadillac CTS. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Cadillac CTS based on all problems reported for the 2003 CTS.
My brakes and rotors had to be replaced after only 20,000 miles. Within 6 months my brake pads again needed replacement. I now have 34,000 miles on my car. This needs to be investigated. These brakes and rotors should not wear out this fast.
