I have a 2018 G80 Sport. After about 8 months I stopped receiving SiriusXM traffic data. I receive all other SiriusXM data. Refreshing the signal does not help. The same thing happened with my 2015 Genesis. With the 2015 Geneis the dealership replaced the head unit twice and the antenna once and it still did not resolve the problem. Is anyone else having this issue with their 2018 G80? The dealership seems to be at a loss on how to fix.
