fletcher969 Posted September 5 Report Share Posted September 5 (edited) Hi all, Audio file and video link provided near the end of post. For the record, the shudders remain, but I'm working on identifying it using FORScan. 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 (see below). I initially thought cam phaser(s), and/or timing chain, or turbo waste gate, but again, there were those shudders... BTW, the loud 'scraping' (rattle) sound you'll hear at about 6, 9, and 14 seconds is when the RPMs are dropping back down. Thanks. ----------------------------------------------------------- UPDATE: The odd metallic rattle/chain-scraping-like noise heard at 6, 9, and 14 seconds was identified as a failing HPFP (fuel pump) which was replaced along with its cam drive piston (whatever it's called). That took care of the noise you hear in the audio. For the record, after replacing the HPFP there was another tapping noise discussed here: Video and audio of the noise discussed in this post: https://drive.google.com/file/d/1CkJgT8a2biDWg7ZpLnIagJD2tjD-UOcY/view?usp=sharing PXL-20250903-062532269.mp3 Edited October 30 by fletcher969 Quote Link to comment Share on other sites More sharing options...

No issues at lower speeds and other than the annoyance of the noise, there are no other issues. If the noise you're hearing is coming from the back of the dealer, check for a TSB that applies to the rear differential. Not sure if that's where your sound is coming from, but I do know there were some issues with improper oil levels or something similar that lead to failure. The differential on my GF's vehicle was replaced when the dealer took delivery of it (used), so I'm assuming it was on the way out.

Cardi Posted October 24 Report Share Posted October 24 Problem solved. Someone mention checking the nuts that tighten the license plate in the back. They were tight but left space for the lower part of the plate to move freely. I replaced the nuts for others bought at an auto part store. It was actually the license plate's lower part flying freely with speed and making the noise. Nuts replaced, license plate cannot move anymore. The noise is gone.

The license plate was the source of mine too. I also noticed (new noise) that the trim pieces on the roof, both sides, just above windshield can make flappy/tappy noises at highway speeds and when I physically tap on them by hand, it replicates the noise. 1 Quote Link to comment Share on other sites More sharing options...
