The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

On 107 vehicles, one or two welds on the rear door upper hinge may not be to specification. This may cause the door strength to be reduced in a side impact crash. Dealers will inspect the welds and install a bolt to secure the hinge if any are found to be out of specification.
