I have not seen anyone post these additional symptoms yet and wanted to include a few of my other observations. Of course, I experience the same issues as the rest of the Genny owners here. However, I have also experienced the navigation lock up in the middle of a trip, which is frustrating to fumble with my phone while driving to get to my destination. Also, my G80 has the heads up display with the speed limit. After the system locks, the speed limit freezes and is incorrect. On occasion, I subconsciously rely on it while driving and have noticed myself speeding when the lockup occurs. Also, while the system is locked, text messages are not received by the unit via Bluetooth connection. While these issues are not serious primary system malfunctions, it does negatively contribute to driver safety.
I am happy to see there is a workaround to cancel the TravelLink service I paid when I bought the car (sorry, complimentary service). I am debating the SXM call to tech services, but am concerned they will give me $5 for my trouble (as another has pointed out). My patience is running low after 5 weeks with this issue so I might make the sacrifice. Thanks to all that have tested and contributed to this thread.
Maybe time for a class action lawsuit discussion. I also consider whether Motor Trend or Car and Driver might be interested in the story. I have considered a report with NHTSA. After a recent accident with a GV80 that caught the attention of the media, I would imagine an issue like this might garner more focus for Genesis / Hyundai, regardless of blame.
Thanks for listening to my frustration and ranting. Drive safe.
