2017 GT Blob & Rattle

[Paul McWhiskey]

While on a road trip all of a sudden had a plastic tapping sound start on the passenger side behind glove box area. Pulled off highway and did visual in battery box area under hood. No obvious problem. Needed to get to destination so decided to let it self diagnose. A week or two later I found a glob of black sticky stuff in glove box. Removed box and did not find anything obvious where it had come from. The rattle sounds like windshield washer line tapping on sheet metal. Gets worse when driving into a strong head wind. No other problems. Planning on pulling r/f wheel well liner to recover lost battery cover fasteners and hoping to find cause of rattle.

Anyone have a similar experience?

Solutions?

Where are all the rattle magicians?

Ok, admit it. You don’t know EVERYTHING about Mustangs.

My '16 Ford Police Utility had a similar sound at highway speeds. In my case, sounded like it was up around the rear view mirror. It turned out to be the cowling at the base of the windshield. Ya know, the grill for the HVAC, etc. It was vibrating at speed and buzzing (I assume) against the windshield. I replaced it and found some minor updates to the part.
