I had a similar thing happen years ago to a different car when I lived in NY and had the window replaced in brooklyn. They never did get all the glass inside the door and it would drive me nuts everytime i hit a bump

Im bring it in to the dealer and they assured me they would get all the glass out.

I really didnt have anything visable in the car. But they figured people leave their wallets, bags, watches, phones, etc. in the cars while they work out.

Could you beleive my dealer wants $300 for the rear window pull up shade
