did you ever find out what it was? I’m having the same experience with braking mainly on downward hillsNov 12, 2013
Hey guys. My 06 AT v6 coupe has developed an interesting problem. When I brake and come to a stop, I feel a "pop" right under my left foot, maybe about a foot away from the pedals towards the seat. I also feel it when I accelerate. It doesn't appear to be making any noises so far, just a sensation in the floorboard. It's definitely something new though.
Any idea what to start looking for? Seems like something might be loose?
