Update 3: Just got the call that the dealer thinks they found the culprit. One of the exhaust pipes between the manifold and muffler is hitting the cross member. This isn't a surprise since the engine was replaced last year which inevitably means they had to remove and reattach the exhaust. That being said, the work was done by a dealer in Arizona with the previous owner. So this dealer is quoting me $240 to reposition the pipe so that it not longer makes contact with the cross member.
Question for you all, shouldn't this be covered by the 60k power train warranty? I have 44k miles on the odometer.
Update 4: FML. Dropped the vehicle off at the dealership yesterday. They diagnosed the problem and told me that the exhaust was making contact with the crossmember. Unfortunately, their fix didn't work. Drove it around the block a few times and didn't hear the sound after I picked up the vehicle. Was nearing my home and rolled the window down again. Lo and behold, heard a loud pop when executing a left turn at about 15 miles an hour. Called the dealership and was told to bring it back for another look... This time I'm going to go for a ride with somebody there so they can hear it with me.
Also, I feel super dumb for completely forgetting to show them the video that I made...
