I have the exact same rattle......identical on my 2019 titanium. didn't notice it till one day when I was outside the vehicle with it running. this thread has been very helpful. thanks to all who had input, after our trip I still might have the dealer check it just for piece of mind. not that I dot believe anyone but god forbid something went wrong and they say well you should have had us check it. fyi our edge has 1300 miles
