My 2021 Ford Escape SE Hybrid has about 200 miles on it. It was nice and tight when we test drove it at the dealership; it didn't have any squeaks or rattles on the 50 mile drive home. But today when we got into the vehicle there was a rattle in the driver door area. It sounds as if it is right at my (the driver's) ear. It doesn't seem to matter if the window is up or down. The outside temperature hasn't changed a lot since we got the car. We haven't hit any big bumps that might have shaken something loose. I'm reluctant to take it into the dealer already and wonder if they can do a decent job identifying a rattle in the door. I hate to think of a mechanic taking the door panel off just to check things out. Does anyone have a suggestion about things I can check or how to trouble shoot this?
