I just bought a used 2013 Model S and the owner purchased the extended 4 year service agreement. I went to tesla today to replace a key fob cover and to schedule an appointment to check my tire pressure system which appeared on my dash saying to contact tesla service. They said that my tpms system wouldn't be covered under the extended service plan. Is there a difference between an extended service plan VS extended warranty? I was under the impression buying the car from the guy that it had an extended warranty. I read a few articles regarding how little the extended service agreement covers. And im wondering.. is there an extended warranty I don't know about? If my door handles stop retracting or the trunk liftgate stops working.. I'm assuming the service agreement doesn't cover that.. Kind of disappointed cause I bought the car pricing in the service agreement.. and now I realized I should've just bought a cpo that comes with 4 years of warranty..
