Update: Brought 2013 Model S85 in for it's final service prior to extended warranty end date in mid 2019.
Fixed air suspension. Both rear struts replaced. Came back from 10 day vacation and found the Model S rear suspension was lower than the front. Took picture. Tesla diagnosed as a leak in the struts, ordered the parts and contacted to book service when parts arrived a few weeks later.
Fixed power steering bolt recall. Parts had been available for months, but I wanted to do one service to cover any and all items prior to end of warranty.
Rear hatch lift gate strut showed rust, Tesla replaced and updated firm ware to work with the newer strut.
Tesla provided 2016 Model S loaner for the day.
Service started at 9AM, was completed at 1PM, car cleaned and charged.
For the 3 year period of ownership, we have spent $0 on maintenance and were provided loaners or rental for every service, and one of the appointments Tesla came to our house and took the car away and returned it. Very satisfied.
As noted up thread, the car keeps getting better, the new software/firmware continues to impress.
Tesla has a fantastic battery management system, it's absolutely a charge and drive product, no degradation in 4 years.
Note on the loaner, the 2016 had "auto pilot V1". I found it useful in the heavy traffic on DVP. The car display showed the traffic around and made it clear when it recognized traffic merging in and left space, and I felt confident after 20 minutes using it. My wife didn't like it, and wanted to close her eyes as a passenger when I had the car in auto driving modes on the DVP, but was Ok when the traffic was lighter.
