Yeah, same here, not gonna take it in just for this. I also pulled the $h!t out of it and I don't see it affecting the integrity, just looked like some flex on the plastic as I pulled.The photo in the OP at first did look like a seam from manufacturing but the one posted by Quick as well as my own definitely look like a crack. Drivers side only.
I dont think it will affect integrity but I will put it on the list of minor things to take care of if I ever break down and take it to the dealer. That won't be until I need warranty work or critical recall.
