When the display went blank, did the engine stop? Some of us have had stalling issues which required a new ECU to fix. Not being able to shift is a mystery to me. There shouldn't be anything electrical to cause that. However, if the engine stopped it might be hard to downshift if moving, never tried it, though.
There are also a couple of electrical-related recall notices on the bike - do you know if those were done?
Check your battery terminal connections...if those are loose all sorts of odd electrical things can happen.
Most of these bikes have a change in sound with the clutch out that goes away when you pull it in, but I wouldn't classify it (at least on mine) as a turbine sound...more of a rattly kind of sound or fluttering as you mentioned. If that's the case it's normal for this bike.
I had a similar situation in that I bought the bike about 80 miles away, but took it to a nearby dealer for warranty and recall work. Mine had more miles and it was about a year later, though. If it's warranty then Suzuki will pay no matter where you bought it. I suppose you could run into a situation where the nearby dealer might be less than cordial because you didn't buy from them.
