WHAT'S WITH AVEO'S PASSENGER SIDE WINDSHIELD WIPER? IT SKIDS OFF THE WINDOW AND WIPES THE TRIM. WHEN I FIRST BOUGHT MY CAR I THOUGHT SOMEONE MADE A MISTAKE AND PUT ON THE WRONG SIZE. WHEN THEY NEEDED REPLACED, I REPLACED THE WHOLE ARM WITH A SET MATCHING MAKER SPECIFICATIONS. AND MADE NO IMPROVEMENT AT ALL. THE TIP OF THE PASSENGER SIDE WIPER STILL SWINGS CLEAR OFF THE WINDOW. DID SOMEBODY MAKE OFF WITH THE DESIGNER'S RULER? ANY CHANCE THEY MIGHT GIVE IT BACK? I'D REALLY LIKE A WINDSHIELD WIPER THAT FITS; DON'T REALLY NEED ONE FOR THE TRIM...

IGNITION SWITCH IS OVERHEATING. THE LONGER THE CAR IS DRIVEN (10-15 MILES) THE HOTTER IT IS BECOMING. IT HEATS UP SO MUCH THAT THE IGNITION KEY BECOMES QUITE HOT AS WELL...BUT THE SWITCH ITSELF IS EVEN HOTTER. I FEAR THERE WILL BE AN ELECTRICAL FIRE STARTING SOON, AND HAVE ALREADY DECIDED TO STOP AT INTERVALS TO TURN THE IGNITION OFF SO IT COOLS DOWN. IT DOESN'T MAKE ANY DIFFERENCE IF IT'S DRIVEN FAST OR SLOW, DRIVING STILL HEATS UP THE IGNITION SWITCH. THE ONLY ODD OCCURRENCE THAT MIGHT BE SOMEHOW CONNECTED IS THE RIGHT TURN SIGNAL BULB NEEDED REPLACED SINCE THIS STARTED.

WHILE BACKING UP MY VEHICLE I SHIFTED THE TRANSMISSION FROM DRIVE TO REVERSE. THE ENGINE IMMEDIATELY ACCELERATED TO APPROXIMATELY 500 RPM. I IMMEDIATELY PUT MY FOOT ON THE BREAK, SHIFTED TO NEUTRAL, AND TURN THE IGNITION TO OFF. I WAS ABLE TO IMMEDIATELY RESTART TO VEHICLE WITH NO PROBLEM. THIS HAS HAPPENED BEFORE TWO OR THREE TIMES. ONETIME WHILE THE VEHICLE WAS IN DRIVE AND I HAD TO PRESS HARD ON THE BREAK AND SHUT OFF IGNITION TO AVOID AN ACCIDENT. I SEEMS LIKE IT MOSTLY HAPPENS WHEN IT IS COLD OUTSIDE ( IN THE 30"S F) . I THINK THIS IS AN UNSAFE SITUATION AND AN ACCIDENT WAITING TO HAPPEN.

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.
