The G80 is equipped with a bluetooth system that should read incoming text messages while in drive. (see https://www.youtube.com/watch?v=cxfPQ37jJbI&t=6s) Instead, after I select "Listen" the car tells me "unavailable while Driving." When I close this system message, the display shows the first several words of the text message - allowing me to read the message while in Drive. This is unsafe. My vehicle is not the only one experiencing this problem - see https://genesisowners.com/genesis-forum/threads/voice-text.37457/ for other reports and more details. I have contacted Genesis USA several times with no luck. I have returned the car for service multiple times with no resolution.

245/40 R20 (FRONT) 275/35 R20 (REAR) The two front and one rear tire experienced sidewall failures within the first 25,000 of use. The tires have been disposed. I thank god that the failures did not occur at highway speed which could have caused serious injury to me and other motorists. There were no warning before the tire failures. After the third failure occurring on 2/12/23, I changed all four tires to Michelin Pilot Sport All-Season.
