the picture shows the top side panel has a partial rise maybe 5-6 inch long. I noticed that about a year ago. My QX4 is parked along the street, but the passenger side faces North so less sun shines on that side. Driver side does not have anything like that. I never took door panel off. Not a big deal but I am just curious how that happened.

If you pop the panel loose you'll probably find embrittled plastic underneath that simply split with old age. In my grandma's words, "Age-atism is a b%&#@."

Thanks for the reply. When I get time I will take a look.
