Im posting to this to track the progress and share my experience along the way. On september 19th I took delivery of a cpo 2013 model s 85 with 23000kms. Ive probably put on 700kms since taking delivery and enjoying the car tremendously, I will make any excuse to go for another drive when I can or to sit and tinker with the user interface. Today I had a great get together and lunch with some local Tesla owners. As I was driving home i received 2 messages - low 12v power - low battery power I turned the car off, and back on, now I had 4 messages showing: The 2 above and - pull over and park car as system will shut down - service required I tried to plug the car in, but the recepticle showed red and wouldnt accept the plug in. I called the roadside assistance number and they already had my info up. The tech pulled my logs, asked me to do a reboot and after nothing helping my situation said he'd get back to me by tomorrow after the engineers review the logs. Not even an hour later I receive a call from Mark, the GM in vancouver, and he informs me that it looks like the battery failed and that they will replace my battery. He informed me he will set me up with a luxury loaner from enterprise first thing tomorrow. Unfortunately there are no loaner Tesla's in alberta. His promise was that i should have the car back within 10 to 14 days. I am impressed so far with how quickly they moved, especially being that I I sunday. As things progress i will post more. For those considering to buy a tesla this would be a major fear, as was one of mine, but the 8 year unlimited km warranty combined with their customer service should make this acceptable and provide some comfort.
