I have a 2006 TL base the passenger side front right at the door sill the carpet will not stay in place its constantly pulling back i can manually put it back but in no time its back undone any suggestions would help

 

Same thing happening to me. Looks like the hook on that side broke. I haven't pulled the driver's side to see what the difference is. Did you find a fix?

 

That's what was wrong with mine, the hook that hooks into the frame of the car and into the plastic that covers the carpet broke off. I just replaced the carpet in mine and it's so much nicer now to not look over and see the carpet sticking out.
