Possession! How To Exorcise?

And with that catchy, yet non-descript, tile my 1st post.

Bought the 2011 R-Spec about 4 weeks ago, 2nd night driving I start and the traction control light is on and wont go off. Cycling the key "fixed" it. That's happened once more.

Next up was the steering wheel volume control ONLY turning the volume down.
Again cycling the key "fixed" the problem. This happens often.

No volume at all from the radio, FM, XM or Bluetooth, again cycling the key.

That dern traction control system again! this time flashing on downshifts. Not full power downshifts or the like just regular downshifting.

The steering wheel volume control now activates voice command.

The common thread is all of these problems are temporarily fixed by cycling the key. I've mentioned this to service and the sales people while back for an unrelated issue. they both immediately said it needs to flashed.
I work on transmissions and am somewhat familiar with flashing ECMs. The TCS and radio are two separate items, I'd think. And I'd doubt the radio has a flashable controller.

Want opinions before I take this in to service, especially since I'd have to take a day off work since they "can't check these issues on a Saturday" and "Hyundai doesn't give loaner cars".

Also interested in if anybody else has had similar problems. I've seen the traction control problem mentioned on automatics but not manuals. I haven't seen the other problems mentioned.

The radio IS flashable. There is an update to both the radio and the BT avaibable. I can tell you,hyundai DOES give loaner cars. YOUR hyundai dealers does not give loaner cars,some do,some dont. If there is another dealer nearby you,call them and see if THEY give loaner cars.

I have noticed that my steering wheel controls will act funny when it's really cold outside. For example, the volume up will activate the bluetooth.
Winter wheels? You can't have same size wheels on this car. It needs larger wheels in the back (staggered setup) or else the TCS will go off anything over 40~60 mph. If TCS is constantly engaging because of this, it will stay on as it will think that something is wrong.

Stereo issues; try turning off the stereo an then turn it back on, when anything happens with it.
I've had my TC light go on randomly a few times while driving too... turning off the car and turning it back on would get rid of the light. I know I've heard of a few other people that had that problem too.
I have about 2300 miles on mine and have had the traction control light once (fixed by re-start) but no other electrical/ecu gremlins.
Check the shipping fuse that's in the interior fusebox. Its a little yellow holder with two fuses in it, They are shipped unplugged and sometimes don't get pushed in all the way.
Go to Hyundai Service Website

Register and you can pull all the TSBs about ECM/Radio/Bluetooth flashes to see if you fit and to print off and take in to them. To do all three if needed shouldn't take more than half a day if you have an appointment to do the work and then have them check it with a test drive which you should request that you drive and have the tech/adviser ride along.
*Update*

Check this thread - http://www.gencoupe.com/general-discussion/20625-anyone-see-trac-control-glitch-startup-5.html

Page 5 Post 100 shows the whole TSB issues to cover fixing your TCS light issue. The Radio and BT TSB flashes are on HMA and look similar to the one posted on the above link at HMAService.

Hope this helps
Thanks guys. I've been monitoring the thread.

Called another dealer and the loaner car is a courtesy from the dealer NOT Hyundai.
I dumped two cars for the Genesis. My daily driver and my fun car. Turns out two cars are needed but I digress.

I'll have to make an appointment and drop the car off.
It's cold as a witch's, you get the idea, it has not acted up recently.
