It seems back in the late seventies GM went to aluminum bumpers with steel reinforcement. You saw a lot of wood bumpers on those cars. I had a Buick wagon and noticed that the aluminum was detaching from the steel. Buick wanted $300 to replace bumper. (Out of warrantee). I called GM customer service and told them about my problem. I suggested they talk to an electrical or corrosion engineer about galvanic action between dissimilar metals. GM called back and asked when I would like them to replace bumper at their cost. I hope the auto guys have figured this out.

Those old bookworm GM engineers, now retired thankfully, weren't as bright as they think they are. :B
