i have got the weathertech floor mats, about two weeks i noticed some oil on the mat this was on the drivers side, didnt think to much about it so i cleaned it up, yesterday oil was back same spot. this is a small leak, dont smell like brake fluid. i wonder if something was over greased at the factory and when it warms up drips down on the floor the leak is located just under the brake pedel. glad i got rubber mats.

 

I had the same exact problem. First time I saw it on my weathertech mats (would never noticed it with the stock carpet mats) I thought I might of had something on my shoe but about 2mo later it happened again. I had the dealership take a look and it turns out the mechanism on the brake pedal for the adjustable pedals was leaking - not a safety danger though. They replaced out the whole adjustable pedal.

 

thanks for your reply, i am due for my 3000 mile service i have them check it out.
