One problem related to brakes failed has been reported for the 2003 Chevrolet 1500. The most recently reported issues are listed below.
No warning!!!(soft brakes or dashboard lights), truck brakes completely failed in traffic! after stop light, in slow moving traffic. Silverado crashed into small car and then, that car into another. No injuries, minor damage. I loved this truck. I have a folder an inch thick on this vehicle's maintenance! never has it's service been ignored! chevy should be accountable for this catastrophic failure of brake system. I would never buy another. Extremely disappointed with the ridiculously cheap parts used. Made in USA, chevy tough!!!! what a bad joke!.
