Has anyone else had a problem with Evenflo straps fraying? I have a Symphony e3 with a DOM of 2011/10/03. By chance I happened to notice the strap was starting to fray. Upon further investigation I found that both straps are fraying. I contacted Evenflo immediately. They are refusing to replace the seat and the straps cannot be replaced. The seat has always been in my car. My car and the rest of seat show no sign of any damage. Evenflo is telling me an animal chewed on it. Just wondering if others have experienced fraying or an animal being in your car without you knowing!
