I posted earlier that I picked up my new MS P85 at the end of August with SW version 5.0 and the navigation system frequently got lost or the arrow just spun around randomly making it virtually useless. I had the San Diego service center pick up the car yesterday and will get it back today. Here's what Brian Todd and the delivery guy told me:
The Nav problem is well understood by the engineers and seems to be a problem in 5.0 firmware. The program is going through some initial loops and checks upon startup that it shouldn't. Brian said the engineers will be releasing a firmware upgrade in the next few weeks that should definitively fix that problem. I believe it's only happening on 5.0 because my loaner car had 4.5 and the nav worked perfectly.
The delivery guy told me that they are actually loading 4.5 software on new deliveries at the service centers now even when they come with 5.0 from the factory because of the nav system and other bugs in 5.0. So if you're bummed you don't have 5.0 don't be - they are still working out the bugs.
I also had very squeaky brakes at very low speeds even after 700 miles of use. I have the 21" wheels and Brian said that the larger wheels amplify the sound of the pads on the rotors so they replaced my rotors with the newer design that has a rougher surface to dampen the vibration and noise.
Although I didn't have any problems reported, they also added adhesive to a side panel and some additional brackets to the panoramic roof which they said others had complained about so they just took care of it as a preventative measure.
They dropped a beautiful MS 85 off as a loaner at my office and were incredibly professional and courteous to work around my schedule (I made them reschedule due to a meeting conflict the day before the original appointment). I was sent emails and voicemails a few times over 24 hours to give me updates on the status of my repair. Really an outstanding service experience!! I highly recommend Brian and his team if you are in Southern California and need any service done.
While not ideal that the nav system on a brand new $100K car doesn't work, I have nothing but praise for the SC and the way Tesla handled it.
