I am a new member to this forum. Just signed up today. I just took my 2013 FFH to the dealer on July 2nd to have a list of things repaired, and one of the things being a ping pong noise. It's funny that I called it a ping pong noise not knowing that first there was a forum and others called it the same thing. At first I got the "we can replicate it" from the service center and then I asked them "did you test drive the car, because I can replicate it in one minute of driving". I took them on the test drive and because I insisted they actually did some research and found the TSB. They ordered the parts but as many of you have found the parts are in back order. They could not give me a date as to when they would come in. I wish I would of found this forum before but regardless the TSB was found. I have other issues with my car that I will be posting in a different thread to see if others are having the same problems. Thanks for all of the good information so far.
