NHTSA Complaint #11229721 — 2010 CHEVROLET COBALT

ONCE CAR WARMS UP, WHILE DRIVING, THE AUTOMATIC TRANSMISSION DOES NOT SHIFT PAST SECOND (2ND) GEAR, AND WILL ALLOW RED LINING WITHOUT SHIFTING UP A GEAR. WHEN TRYING TO PARK, THE SHIFTER WILL NOT ALLOW SHIFTING INTO PARK, AND THE VEHICLE WILL PULL AWAY UNDER THE POWER OF ITS OWN IDLE IF THE PARKING BRAKE IS NOT APPLIED, MAKING LEAVING THE VEHICLE UNATTENDED VERY DANGEROUS. WHEN TRYING TO SHIFT OUT OF PARK SHIFTER WILL BECOME STUCK IN THE PARKING GEAR. THE LIGHT ILLUMINATING AND INDICATING THE GEAR IN WHICH THE SHIFTER IS IN POSITION OF GOES OUT, MAKING IT VERY DIFFICULT TO KNOW IF THE VEHICLE IS ACTUALLY IN PARK OR REVERSE ESPECIALLY COUPLED WITH THE SHIFTER NOT GOING FULLY INTO THE PARKING GEAR. WHEN THE SHIFTER DOESN'T QUITE MOVE INTO THE PARKING GEAR IT CAUSES THE DOORS TO STAY LOCKED AND SOMETIMES MAKES THE MANUAL LOCKS DIFFICULT TO USE IN ORDER TO EXIT THE VEHICLE, IT MAKES THE ELECTRONIC LOCKS COMPLETELY UNUSABLE. ALSO, WHY IN THE WORLD WOULD CHEVY NOT PUT A ENGINE TEMPERATURE GAUGE IN THE DASH CLUSTER? HOW ARE DRIVERS SUPPOSED TO KNOW IF THE ENGINE IS OVERHEATING, WAIT UNTIL THE ENGINE BLOWS UP WITH THE DRIVER TRAPPED INSIDE???
