  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

2015 3.8 with tech. Never really had any problems.

Wondering if there is a fix because I'm two months from deciding to buy at lease end.
 
Still under warranty? This is the time to get it fixed if you can.

Absolutely agree. This isn't something to fool around with yourself. If its under warranty, they need to make it right, whether you keep it or walk away,
 
Found a discussion where an XM radio SW update was causing this on a similar system in the 2015 Sonata. I noticed that this happens when I leave my parking garage and my garage at home where there is no XM signal. I do see the "XM updating" screen, so maybe I need to go on a long road trip.
 
This just started happening to me in the last week, switching from Sirius to AM. I assumed it was a Sirius software update bug. Saw someone else just posted the same problem on another Hyundai forum so it’s not just us
 
The 2015 incident happened right after new years.
 
And just like that, the problem went away. (still cold)
