No problems with my carpet, but my OEM Mats are beginning to wear and they seem to be of similar material to the carpet.My 07 carpet where your heel hits the floor at the accelerator pedal wore a hole through it. It's only got 8000 miles on it, bad design in my opinion. It's at the dealer now getting replaced.
All carpet will wear quickly at your heal. You need to put in mats once you have new carpet.
