Hi Folks, I didn't see anything that matched my question exactly, so here I am posting about it. I've owned my 2013 CPO S85 for just under a year. I couldn't be happier. I picked it up with 35k miles, now I have ~51k miles. I've had it in for service twice for warranty items and I'm taking my car in for a 12v battery replacement next week. I thought while I had Tesla on the phone, I would schedule the 1 year annual service for March (exactly 1 year of ownership & ~17k miles). Tesla is saying they will be performing the "Year 4" service, at a cost of $900, because the car is over 50k miles. Is that really necessary since it was already "refurbished" at Tesla a year ago for the CPO program? The Service Advisor said the last annual service performed by the previous owner was Nov 2015, which I assume was the "Year 3" service. I want the car to be maintained and in great working order for years to come, but for someone that did most of the regular maintenance on my ICE cars myself (oil changes, filter & wiper replacements, tire rotations), $900 is excessive and the wife isn't too happy about it! Any similar experiences or advice?
