Tesla service is absolutely miserable and has been for a while. I'd rather go to the dentist than take my car in for service. It's that bad.
I know whatever BS they can come up with to not cover a warranty repair, they will happily tell me how everything is within spec, not a defect at all, or a defect that is not covered by the warranty. I can also count on them to not provide a loaner, keep my car for days, barely provide any updates, ignore whatever text messages they don't feel like replying to, ignore voicemails and emails, and generally treat me like worthless garbage.
I love my car and Tesla the company and their mission but they have created the worst service experience I have ever endured from a car dealer. The worst part is what can you do? If you receive poor service at a dealer you can go to another dealer or contact the manufacturer but what do you do when they are all the same and there is no competition.
Granted there seems to be a few service centers where they treat customers well.
The rest of us *&%F$@&@ed.
I'm sorry with what you are enduring after you paid for the ESA warranty.
Service should not suck this badly. I honestly also do feel bad for the service center employees. I don't think they are providing bad service because that's what they want to do but they are following orders and doing the best they can with the limited resources they have (or don't have).
For our next EV, if we buy a vehicle that is not a Tesla, it would be only because of poor service.
