Spent from 0745 to 1300 at the dealer this morning with exact issue. Warned ahead of time re: TSB # 19-NA-005. Dealer wouldn't pre-order part and ran a smoke diagnostic test which they report the vehicle passed meaning no new parts needed. Frustration ensued as did the sound, and, then, the tech simply removed the evap and reinstalled.... and, noise gone. Drove it 50 miles home mixed highway/city and noise remains gone.
