    My 2010 with 110k is now making a single yet audible "click" sound when I accelerate off of the line. It makes the same exact sound each time I press the brake pedal at speed. Just one click, not a continuous clicking. What's wrong??

    Well considering it never did this before yet as of a week ago it does it consistently, I would say something is not normal here.

    maybe time to thoroughly inspect and service the brakes. Can you record and post?

    Rotors and pads were replaced on all four corners in 04/2015.

    It sounds as though something is engaging/disengaging but I have no idea what it could be.

    Problem figured out. It is the spring action on the left front brake pad. The pad is sliding ever so slightly and causing the clicking sound. No harm, no foul.

    thanks for your post. i am having the exact same thing, so i hope this is all it is. firestone suggested it was an issue with the brake power brake booster and that i would have to take to the dealer.
