I am so upset - I dropped my kids off at school yesterday and noticed a tear or peeling on the door panel of my MDX about the size of a nickel. No one recalls doing anything that could have caused that. (even after I absolved them of any repercussions) My daughter doesn't even keep her bookbag up front. You would think it would take a sharp object at just the right angle to do that and that you would know when it happened. I'm sure something must have rubbed against it but it must have been casual contact. My cheapo cars I've had have never done that. This has really got me concerned. Has anyone else had this problem?
