Your previous owner should give you the valid Extended Service Agreement=ESA=Extended Warrty (which might vary from year to year.)
For 2013 ESA, it says:
J. Transfer of this Vehicle ESA
Contact Tesla and submit the following:
1. A letter requesting that Tesla transfer this Vehicle ESA to the new owner.
2. $100 transfer fee.
3. This Vehicle ESA.
4. Written evidence verifying all maintenance requirements have been met.
5. A copy of documentation evidencing change of ownership and mileage at date of sale.
6. Documents verifying transference of the Vehicle ESA, if applicable.
Conditions:
1. This Vehicle ESA cannot be transferred to another vehicle. It can only be transferred to a different private owner of the same Vehicle.
2. The Vehicle is subject to inspection.
3. Transfer must take place within 30 days of change of ownership.
4. You may not transfer this Vehicle ESA to a vehicle dealer or to the customer of a vehicle dealer. 5. All remaining underlying warranties also must be transferred to the new owner.
The
2017 ESA is online but I am not sure it's the same for your 2014 ESA transfer procedure.
8 Year Service Plan Agreement (annual inspection plan, not ESA, not extended warranty) is good for either within 100,000 miles or 8 years whichever first.
