I have a late-2016 Model S. My car was included with the recall - for months before the recall was talked about, I was at the service center numerous times because I was having so many problems (backup camera slow to come up, if at all-loss of turn signals-frequent black screen-inability to play music-etc). They were never able to resolve the issues so I was happy when I got the recall notice. The service center told me they were waiting for parts. Then they told me that the recall work would only be done when the system completely failed. My car continued to get worse to the point I no longer wanted to drive it. I decided a couple of weeks ago to purchase the Infotainment upgrade to resolve the issues rather than wait until it failed. I have all of the other available upgrades, including full self driving. I was excited when I picked up the car until I noticed they had dented the screen frame and forgotten to remove the protective film. They told me they would order a new frame and remove the film when they installed it. When I got home, I tried all the new features - they don’t all work. As far as I can tell, it is only the music functions. The worst is the Caraoke. When I select a song, the play button flashes from play to pause rapidly then the screen starts glitching. It won’t play at all. When I took it back, they kept it a few days and said it was fixed. It is not fixed - still does the same thing. The latest thing they told me they spoke to the engineers and they said it was a firmware issue but they had no idea when it would be resolved. Needless to say, I am very unhappy that I paid so much and the car still does not function properly. Has anyone else had this issue or have advise to offer?
