this is odd on my 2013 Ford SVT Raptor I am getting a audible alert that is just 1 chime, I am driving down the road and you will hear the audible chime only once then it goes away. It has only done this twice and all in the last week. I looked in the manual for what the 1 chime audible alert is and I get nothing. I ran a systems test on my truck then checked it out on my sync and nothing came up wrong. No light go off on the dash or nothing just a 1 time audile alert. Anyone know what this could be since the health check reads ok, no dash lights are on for something wrong. The Raptor only has 19,000 miles on it so far. I called service and they have no clue what it is so asking here.
