The weather stripping pulls out very easily, it is not difficult to stuff back into place, you can do it yourself or have the dealer do it. It is VERY easy to do and not at all scary once you're used to how it works. I had to remove mine to put JDM side visors on and can vouch for how easy it is to work with. As for the stereo, honestly, who cares? It's a POS and you'll probably end up replacing it with something better down the road. Just have them replace it if needed. That's what warranties are for.
23K miles in a year, does not qualify as "near new" in my book, but that's my opinion.
