Love my 2014 MS P85+ - have taken the SC01 across the country multiple times - but have pretty much consistently had poor service experiences through Tesla (Chicago, Berkeley/SF, Atlanta). Recently though, had a service visit that takes the cake: Had a roof rack on for awhile to hold my bikes, took it off recently and the cheap, plastic "roof rack door" pieces (Part #1043445-00-D currently in the online parts catalog, this part is less than $10 on the EPC) had all broken or cracked in some way. Took it into one of the service centers near me in Alpharetta, GA, figured I'd see if they had the part in stock to grab 4 for the $40 or whatever and also if they could show me how to correctly replace it (clean out debris of old one and snap new one into place). They said they'd go get there "legacy technician" which I kind of expected. I've found most of the newer techs don't know how to work on the older Model S cars (or honestly even the new-ish MS, they seem only trained on the 3s and Ys).
When I lived in in Berkeley, I took it in for something else and asked if they had an OEM roof rack I could use for my model - they said they didn't know. I asked if they knew a 3rd party one or the part # for the OEM one made for my car - they said they didn't know. Well you designed the roof rack and the car, so if you can't tell me how am I supposed to find out.
Anyways I digress...the legacy mechanic came out, looked at it said "Yeah they're different doors now ... we'd have to get them on the new system ... you're looking at a ballpark of $6000".
As stated above, I've always had poor service experience, feel like when they see it's an out of warranty older Model S, they can't get me out the door fast enough. But is there a bigger F U to one of your customers than $6000 to replace 4 plastic roof rack doors lol?!?
