GENERAL MOTORS IS RECALLING CERTAIN MODEL YEAR 2009 AND 2010 PONTIAC VIBE VEHICLES. DUE TO THE MANNER IN WHICH THE FRICTION LEVER INTERACTS WITH THE SLIDING SURFACE OF THE ACCELERATOR PEDAL INSIDE THE PEDAL SENSOR ASSEMBLY, THE SLIDING SURFACE OF THE LEVER MAY BECOME SMOOTH DURING VEHICLE OPERATION. IN THIS CONDITION, IF CONDENSATION OCCURS ON THE SURFACE, AS MAY OCCUR FROM HEATER OPERATION (WITHOUT A/C) WHEN THE PEDAL ASSEMBLY IS COLD, THE FRICTION WHEN THE ACCELERATOR PEDAL IS OPERATED MAY INCREASE, WHICH MAY RESULT IN THE ACCELERATOR PEDAL BECOMING HARDER TO DEPRESS, SLOWER TO RETURN, OR, IN THE WORST CASE, MECHANICALLY STUCK IN A PARTIALLY DEPRESSED POSITION.
