general problems of the 2004 Chevrolet Avalanche

Retaining hook attached to underside of hood is rusting apart from the hood panel. Chunks of rusted metal are falling off of the area around the hood retaining hook. Vehicle is still under rust warranty but general motors will not honor rust through warranty. Severe rust began when vehicle was approx 2 years old. Partial or complete separation of this retaining hook could cause hood to fly open at speed. Many members of the chevy Avalanche fan club have the same issue, but it is more noticeable on a vehicle with white paint.
