Open the full vehicle complaint log (all categories)PARKING BRAKE WILL FAIL TO DISENGAGE FULLY (WHEN DISENGAGING THE PARKING BRAKE) OR PARTIALLY ENGAGE ON ITS OWN WHILE DRIVING. THE RESULT IS THAT THE CAR EXPERIENCES INCREASING DRAGGING, POOR ACCELERATION, AND SUDDEN STOPPING. THE CONSOLE BRAKE LIGHT FAILS TO ILLUMINATE IN ALL INSTANCES AND FAILS TO INFORM THE DRIVER THAT THE PARKING BRAKE HAS ENGAGED. WHEN RELEASING THE PARKING BRAKE FROM A PARKED STATE, THE PARKING BRAKE PEDAL RAISES AND INDICATES TO THE DRIVER THAT THAT IT FULLY BEEN HAS DISENGAGED. THE PARKING BRAKE LIGHT ALSO TURNS OFF. HOWEVER, WHEN THE PARKING BRAKE IS ENGAGED AFTER DRIVING THE CAR, THE DRIVER DISCOVERS THAT THERE IS NO RESISTANCE/PUSHBACK ON PARKING BRAKE AND THAT IT FAILED TO RELEASE IN THE FIRST INSTANCE. AGAIN, IN THESE INSTANCES THE BRAKE WARNING LIGHT IS NOT ILLUMINATED. THIS ISSUE HAS OCCURRED IN SEVERAL INSTANCES IN NORTHING CALIFORNIA UNDER DRY AND FAIR WEATHER.
