Owner report 11457046 · 2022-03-16 (March 16, 2022)
We took the vehicle in for the ABS recall on the 2020 Genesis G80 [XXX] The Dealer changed the Fuses and told me the fuses where changed from a 10 amp to a 20 amp fuse. This seems to be the wrong way to go for a defective ABS module. Then they told me it is ok to park the car in the garage.

It is dead everyday and I have to jump it I noticed when I attach a power source it makes very odd noises. I feel the current recall you have on the g80 2020 may be the issue. It runs extremely hot wit no warning lights showing. I have had a lot of brake dust and the car is hot fast. Also issues with usb and when connected to phone it sound like crackling and volume sounds odd unless I unplug and replug. Replaced battery twice in a year
