I have a 2019 Model S with 8000 miles on it. Since the last software upgrade about one month ago, voice commands will display and then be ignored. I cannot perform hands free navigation, phone, or music voice commands, Customer service said I must wait for the next software upgrade which will have a fix for the issue. I have requested a repair, in the repair center or mobile, as a safety issue, and was told they will not schedule it. I tried scheduling on the mobile app, was given a date within a week, and it was cancelled the next day with the message I must wait for the new software upgrade. I wrote back to the cancellation message to protest and request the appointment be kept or to get a call back and was ignored. I called and insisted to speak to the Costa Mesa, CA service manager, was put on hold for over 30 minutes and then gave up. Any advise would be appreciated.
