Hope you can help me, good people of Optima Forums 
Few weeks ago I started to hear rattling sounds in my 2017 Optima PHEV -- it happens every other time that I break, video here: photos.app.goo.gl/Gs4GYFhY2N8Zzphw8
Dealership said they'll charge $250 diagnostics fee, before they can tell me what's wrong -- and can't guarantee this will be covered by warranty, even though my Optima is only 2 years and 20K miles -- so hope to get insights before I give car to services.
Thank you!
Kirill
