2003 Pontiac Bonneville Owner Comments

problem #2

Jan 012007

Bonneville 6-cyl

  • Automatic transmission
  • 35,900 miles


When applying the brakes the pedal sometimes goes almost to the floor. Sometimes it feels mushy with a fluid feeling pedal push back. A click noise has also been observed. It is possible to stop the car but the stop feels unstable and dangerous the car has 36,600 miles. While still under warranty in 2006 the dealership could not find the source of the problem. It seemed to go away for a while but has returned (worse than before) in late January 2007.
