I did an OTA update that made the rear view camera work intermittently. It would just flash an image every couple of seconds instead of a live stream. I took it into the dealer, and on the way, it totally gave out in the middle of traffic in a very unsafe way. I was flashed with many warning signs and was not able to get it started again for 5min by just turning it on/off again. I finally got it to the dealer and after 6 weeks they told me that something spilled in the cup holders and fried the backup camera and drivetrain components. I find it extremely off the drivetrain and safety critic…

I pulled the vehicle out of my garage yesterday and drove it out and turned it around and put it in reverse to park it on a very slight incline on my driveway close to the garage to clean it, put it in park, and shut if off. I spent a couple hours vacuuming and cleaning it. I then went to turn it on to back it into my garage for the night and it lurched backwards in an alarming scary way - I rolled my passenger window down and asked my husband who was right there if there was something in the way that I had just tried to run over with my car. He assured me there was nothing in the way so I…
