SPECIAL POLICY ADJUSTMENT DOOR HINGES
Model and Year:
1988-89 CORSICA & BERETTA W/8.7 MM CONICAL P INDOOR HINGES
To: All Chevrolet Dealers
General Motors has determined that certain 1988-89 Chevrolet Corsica and Beretta model vehicles with 8.7 mm conical pin door hinges have had a door hinge break while opening or closing a door. If the lower hinge breaks, the door may require more effort to close, or a popping or scraping noise might be heard. if the upper hinge breaks, the end of the door nearest the door handle may drop down, making the door difficult to reposition and close properly.
NOTICE
It has been determined that a primary cause of door hinge fractures is corrosion of the door hinge. Accordingly, the majority of vehicles experiencing this condition will be located in high corrosion areas (Canadian Maritime Provinces, New England, Great Lakes States).
As a result (and also due to limited parts availability) owner mailings will be phased out first to owners of vehicles located in high corrosion areas and then expanded to include other regions. Dealers should be certain to consider this corrosion factor when placing parts orders.
