I'm also facing issues 2-4 that you mention and made a post about it here too.

Hard to say whether the wireless connection drop issue is because of KIA's firmware or iOS. I just updated my iOS, so we'll see if that resolves the issue, but no firmware updates on KIA's side as far as I know.

For the roof liner issue, I'm having it both on the driver and passenger side. At least for the driver's side, I confirmed where the spot was my pressing up against it while driving. This made the noise stop, so it makes me think that something is not seated/glued properly up there. Can't say for sure on the passenger side since I can't reach the area when driving, but it does sound like it's coming from the sunroof area.

As a point of reference though, my previous ride was an Optima EX with a sunroof. The sunroof will definitely make noise, especially over time, since there's so many parts up there, but the tricky part is figuring out whether it's normal or an issue. Mine had an issue, but it was a nightmare dealing with KIA service departments trying to get it fixed, so I dread having to possibly do that again. Also, the rattling/vibration issues are something that seems to exist across different KIA models from what I've researched online. And these are all with new cars.

Another member made a good suggestion of contacting KIA corporate first then going from there. I already sent them a message, so I suggest you do the same. Hopefully this can start to bring it to their attention that these are known/common issues and must be addressed somehow.
