Hatch is an easy fix. Adjust the bumpers or put a couple slim / thin clear bumpers where the bumpers set on the hatch frame. No rattles.

The sticky ignition issue ........ all these feel sticky, even when new. Make sure you turn the steering wheel to loosen the tension on the switch before turning -- it help and will help longevity of the switch. Other than that, I'd suggest doing the fix. I haven't done it yet either (only 14K miles on mine right now) but will likely do it within the next year or so.

WRT the fog light, I bet it was stuck on by the previous owner or the dealer as a temp fix. You may want to take it back and have them do it (it's worth a shot anyway). If not, there's a number of ways to get it on and seal it.

Not sure what to do about the CD other than try what previous thread noted.

Hope you have better luck going forward. The cars are a lot of fun, as long as they don't become a pain in the ****..........
