I'm sure this may be normal, but it seems a little odd to me how the black plastic hooks for the bottom of the front floor mats aren't really "anchored" to the floor. It's like I can just lift up on them and they lift the carpet up, etc. I guess I would have just expected for those hooks to kind of be more secured than they are if that makes any sense.

 

The studs on the bottom of the floor mats are just to keep them from sliding around. The only anchor is on the driver's side. That was an excellent idea since an out of place floor mat on the driver's side can cause all types of problems.

 

Yes indeed...look at what happened with Toyota recently!

 

Mine is the same way, I wish Nissan did a better job with the way they attached the hooks to the interior carpet of the car, I feel like the carpet is gonna tear the way the floor mats pull on the hooks

 

My hook has never let my mat slide anywhere, which is all they are there for. I have not yet heard of a hook coming loose from the carpet in this '09. Under any normal circumstance, there should never be a great pull against this hook. Even if the hook broke, these OEM carpeted mats do not have the grippy rubber edges that have been catching brake pedals in some cars, and when I took the mat loose from the hook and checked, I didn't see any way this OEM carpeted mat could catch the accelerator unless it was intentionally rolled up underneath the pedal.

I don't know how this would play out with the all-weather mats, which may be more grippy.

If my car was suddenly revving wildly, I would instantly turn the ignition off, thinking only of keeping the engine from destroying itself. Of course that makes steering and braking very difficult. But at least, the car would not head off into space at 120 MPH and explode, like the Lexus in California.
