Nearing 30,000 km and this might be happening to me. I can't reproduce it 100% of the time, but when braking gently from speeds of at least 50 km/h, I can hear a strange click half the time. It's not "ting, pop, click", but it's a click that I'm sure didn't happen before. It can also be heard when accelerating gradually from a stop.
Well, I have an ESP that lasts till 2019 or 100,00 km - time to visit the dealer and see if I need this TSB fix!
My FFH got the TSB done in 2013, probably a ways back in this thread... the sound would occur from a stop of when going slow and quiet and getting back on the gas it would make this ping-pong sound, but would not happen when applying the brake -- only when getting back on the gas after stopping or after being on the brake to slow up.
Then last year it started doing it on the Energi (had 64k miles at the time), and the sound was so similar to what the hybrid did, but then the dealer checked it and found the cause to be some support bracket insulator had worn (very surprising since I drive smoothly and rarely ever would slam on the gas) -- below was the repair order. So who knows, if you are getting that type of sound it could be the thrust washer thing that was the cause of the TSB, could be the insulator thing as shown below, or could be something else.... let us all know!
