I purchased the vehicle new and have had it in the shop 6 times for braking problems. My wife drives like a grandma so I know its not due to harsh braking. I have also had the alternator replaced, luckily that was still under warranty. Unfortunately when dealing with Chevy, the warranty does not include "normal wear and tear" on rotors or pads. I have noticed that the more frequent we replace them the faster they need replacing. This will be the 3rd time in 2009. I'm over it! This can't be legal. Someone help!
