entertainment system reboot

[jalanjalan]

I've had the car just over a month and am really enjoying it, so I guess this feels like the first argument with a new girlfriend. Anyway, started the car after going to the movies and the display was frozen, and near the bottom, but more or less cut off there was a windows type dialogue box with the yellow triangle and exclaimation point just like when the home computer spazzes out. I stopped and restarted the car and then the screen was totally black. It seemed to reboot with the hyundai logo after about 2 minutes and worked fine.

Its a 2013 r-spec sedan.

There are bugs in the software/computer system that occasionally results in odd glitches.

In complex systems with many inputs (such as a modern, heavily computerized car) the CPU can sometimes get bugged by what is called a "race condition" where very low level settings get glitched when one signal arrives before another and the CPU is not capable of handling them out of sequence. When the software and computer hardware engineers are under strict deadlines (such as annual car launches) they often don't get enough time to fix 100% of the bugs. The ones that occur randomly/intermittently are the hardest to catch in the lab and often leak into the field. Ongoing testing/debugging and field bug reports back to the programmers will eventually allow them to ID the cause and put in code to catch the exceptions... but that often comes from owners, or dealers who have verified the glitch and submitted warranty repair claims.

I personally believe that the "silent amp bug" (common to 2009-2010's at startup) is one such race condition bug that has to do with inputs such as the DIS knob, GPS, and door. And I'm pretty sure that a TSB update that was published for 2012's to fix the surround setting bug also addressed the silent amp bug in 2012's, but do not believe it was ever fixed in the <2010s.

Dealers may or may not report these complaints to Hyundai (I presume not), and without hard evidence it's hard for them to blindly accept the spam from the unwashed masses that are us.


Bottom line for you:

Video this kind of thing if it repeats. Without a video, going to the dealer will be mostly worthless unless they can repeat it (and in my experience and others on this forum, dealers rarely can repeat these kinds of glitches).

Alternately you can join the think tank and post your complaints there, including links to videos if you can. At least HMA marketing reads all posts and frequently FWDs complaints to the engineering/tech teams.

Good idea, will try if it happens again.

video tape great idea...if the condition occurs you can reset by pulling the large yellow fuse from the interior driver side fuse panel.

Mine has glitched like that as well. ... Rebooted after a while of hanging...

2013 R-Spec 5.0

. Here's yesterdays reboot. Started the car cold after work. Was probably pressing the knob to "accept" and then putting into reverse when it popped up.

Turned off the car. Restarted. Black screen for about a minute then rebooted and worked fine. Second time now but this screen is different then the one that popped up the first time

Looks like a memory leak.

I suppose I'll bring the photo with me to my next service.

Does this only happen when music is loading or is the last thing used? If so you may have corrupted music files.,

iPod is always connected and usually stop and start the car with music playing. I'm not sure but I think it's a combo of booting/putting into reverse/hitting "accept"/music streaming that messes it up

I would check the IPOD for a virus and bad files. There are guides online on how to do this.

I don't have the manual in front of me at the moment, but doesn't it mention disconnecting such devices before starting the car?
