Hi all, Audio file and video link provided near the end of post. Vehicle in question is my girlfriends. Purchased just shy of a month ago from a reputable dealership with a 3-month/3000 mile full warranty on the engine, drive train, and axles. Vehicle has good service history. It's been driven about 1000 miles since purchase, and it currently has about 97.5K miles on it. No CEL or other trouble indications. No issues whatsoever until this happened. This engine has been one of the quieter direct injection engines I've been around...until my girlfriend started it 2 days ago to run some errands. I heard it from 30' away, so I stopped her, and had her pop the hood. Sound seems to be coming from the top end, more rearward in the engine bay than forward, and more on the right side than the left. The sound lasted a full 10 minutes before I took it on a slooow test drive during which it lasted maybe another 5-10 minutes until I couldn't hear it in the cabin. It sounded pretty normal when I pulled into our driveway. At that point I decided to take it for a 'normal' speed drive, and I noticed during slow acceleration it had 2-3 slight but distinct shudders or 'hiccups' at what 'seem' to be shift points up to around 30 mph. The digital tach needle would 'flutter' about +/- 50 RPMs whenever I felt them. Sport was about the same, maybe slightly worse. Normal and aggressive acceleration seem normal and acceleration was snappy. I'm not sure the noise and shuddering are related, but it doesn't seem like a coincidence to me, but I know there were torque converter issues with some of these Edges. And for the record, fluid levels were checked the night before, and all was fine. Also, when my girlfriend started it up the next day after sitting for about 10 hours, the noise was there, but not as pronounced, and it quieted down after maybe 3-5 minutes. Nights have been cool for a change, but not cold. Any ideas? I want to be able to steer the dealer tech in the right direction just in case it's acting more subtly than what I captured in the audio/video. I initially thought cam phaser(s), and/or timing chain, or turbo waste gate, but again, there were those shudders... BTW, the loud 'scraping' sound you'll hear at about 6, 9, and 14 seconds is when the RPMs are dropping back down. Thanks.
