Genesis GV80 3.5T Prestige and also having this problem. I first noticed it probably in January maybe sooner. I believe it may have started because of a software update. I just updated my car with the brand new update from yesterday 5/12/2022 and nope, still doesn't work.
I haven't spoken with Hyundai or Genesis about the issue yet. Think I'm going to ask now because I've looked for information and can't find anything. Was hoping this update would fix the problem but nah.
My local gas prices is stuck to old out of date prices in the 4.30 range, doppler never worked, but the traffic did work and now nothing works. The new update even talks about how traffic will be displayed but the traffic doesn't work so doubt they even know about the issue.
