1999 olds alero gls, bought the car in may,2004 with 23,000 miles on it. From day 1 I have had nothing but problems with it mostly brakes, car has extended warranty on it. The rotors grind, pulsate, squeak, the calipers make cracking noises sometimes brake pedal goes to floor. The dealership refuses to fix the problem or says it will not do it for the mechanic, when I drop it off I allowed the service manager to hear it he also verified the sound, only to get the car back being told it won't do it.
