I picked-up my new P85 in early September. I had it for 2 weeks and then got an error message stating that I should stop the car and pull off the road. Fortunately, it happened in my driveway. I called Tesla and they picked up the car. It turned out that the problem was a defective sensor in the battery. They replaced the entire battery pack with a "new" one. The rated range when I originally received the car in "daily driving" mode was 240 miles (273 maximum). When I got the car back it was 225 miles (249 maximum). It doesn't seem like a huge problem, but I paid for a new battery and it seems like I got a used one after mine failed. I made an appointment at the service center for next week to look at it. I'm wondering how aggressive other owners think I should be about demanding a new battery.
