I was told, during a test drive, that the suspension was serviceable by third party mechanics. Of course that doesn't mean it's true, but I haven't ruled it out yet.
I got another software upgrade notice yesterday. Of course I didn't install it, but my car was doing some strange things after I got the notice. Maybe this is Tesla's way of telling me I need to install it. The navigation froze up a couple of times and I had never seen it do that before. That was just before I got the install notice. Almost like my car was downloading it over it's cellular connection while I was driving.
When I got to my destination I summoned the car forward a foot or so after I parked. I walked away and went inside the restaurant which was 200' away. From the restaurant I noticed my headlights and windshield wipers were still on. I opened the phone app and it showed the car was unlocked. I locked it with the app, but the car stayed on. I went back out to the car to see if maybe one of the doors didn't get shut all of the way. Doors were all completely closed. The radio, HVAC, and the displays were all on. I unlocked and locked it a few times with the fob and the car stayed on. I got in the car and the binnacle display said that the car was off. I stepped on the brake and put it into drive and then back to park. After that the car functioned like it was supposed to. I had never experienced anything like that before.
