The right side clip on the drivers mat occasionally will let go slightly after a few drives, the passenger side doesn't have clips, more of a raised area to accomodate the floor posts. Sent back the WeatherTechs because of the problem you've experienced all the time like me, very poor for a mat so expensive.wow that's nice. How are the retainer clips at actually holding to the buttons on the carpet? Our WeatherTechs are always pulling away such that I always have to clip them back down. Like, every single time I get in the car.
