That is where the warranty/body shop comes in. The techs are trained to sort this stuff out so we don't have to take a multi-year technical course to own a vehicle. We have the luxury of driving it and leaving the strange noise problems to them.....at least for a few years.
Contact your dealer and show them the problem. Let them advise you on whether or not it's of immediate concern or even part of the accident. If it is not, they should take care of it before it goes to the body shop.
