I searched but couldn't find a thread on this.

Yesterday, as I was waiting at a red light, I discovered that my brake pedal can move laterally from left to right -- maybe a quarter of an inch or so. My foot was pressing the pedal. I then move my foot side to side. If I do it hard enough, I can even hear the noise of the brake pedal jimmying back and forth.

Anyone else notice this? Should I bring my G in and make them tightening it or something?

This should be a warranty item. I would bring it in to the dealer.

The dealer for Acura wouldn't do anything. They said "this is normal" no matter how much I complained.
