Here is how my Tesla Service center experience went:
The phone rings out of the blue one day and Caller ID says it is Tesla.
Lady on the other end: Hi, my name is Jxxxx and I am calling from Tesla
Me: Hi, what can I do for you?
Lady: Well, I am calling to checkup on you and the car. We didn't see you since you drove out of here with a new car 35,000 miles ago
Me: Yeah.. do you need to do an oil change or something?
Tesla Lady: Naa.. we just want to look at the car if you could drive it by when you get a chance. We should probably change the brake fluid and rotate your tires too if you need it.
Me: Ok.. but the tires are wearing evenly, I don't think they need to be rotated.
Tesla Lady: We will look.. maybe we can change the battery coolant and clean your brake parts too.
So I drove in one fine Tuesday morning - $750.00 for 50k maintenance and $250 for brake parts clean up. No tire rotation. I guess they knew they probably won't see me ever again
Car now has 52k miles on it, drives like the day I bought it. I am regretting buying the extended warranty for $4k, but then it is peace of mind.
She forgot to say they saw me when the car had about 5k miles - they replaced the charging port, and talked about a small scratch by the door handle.
I guess I am one of the lucky ones.
Then the wife bought a Mercedes 350GL - used (33k miles). A week later, check engine light comes on. Dealer says it may be because the diesel cap is not tight enough. Felt tight, but opened it closed it just for the heck of it, still check engine light. Dealer says drive it around another couple of days. Finally went away after 4 days or so. Minor issue, but something I don't have to think about in the Tesla.
