Just my .02, 8 months, 22k miles. I've had just about everything in the car replaced that could be replaced. Let's see...
2 door handles
2 door control modules
4 charge ports (the first had a burned out LED, the other three were to troubleshoot a amperage drop during charging)
3 chargers (again, to troubleshooting amperage drop while charging)
12v battery posts (proactive, not my call)
Spline/hub service to address clicking sound (3 visits, once to diagnosis, 2 to fix)
Three visits for leaky sunroof, fourth visit was a new sun roof (lots of wet crotches for driver and passengers, not in a good way)
Windshield replacement because robot at factory ran out of glue and there was a leak
Driver door wiring harness / driver door mirror (this took three visits, and I was the one to successfully diagnose the issue, hurray!)
Three visits to properly align chrome trim pieces
Re-glue other chrome trim pieces to eliminate cracking sound on 45' turns into driveway
New HVAC vents (sounded like a leaf was stuck in there when first delivered)
Three front fan replacements (not sure if all the same one or different)
Various squeaks and rattles that were addresses by the miraculous Teflon tape
Visit to install center-console
Visit to mount summer tires
Currently troubleshooting the whining sound from the rear between 0-20kw and below 30mph
Total of 15 service visits to date I think. Whew, that feels good to get it all down in writing.
I do blame a lot of the issues on the end of production rush in Q3'14 due to the factory shutdown/new production line. And I'd say half of the issues are quality control that should have been dealt with at the factory (but weren't because it's easier on Tesla to let the service center resolve the issue at the expense of the customer's time), and the other half are design/engineering issues where a new bulletin or part revision addressed an already known issue. I do suspect that the drive unit issues for RWD cars may be an engineering issue that will always plague us. There are certain indicators that TM is trying to mitigate this by lowering peak kw and therefore reducing stress in that component to delay/eliminate failure risk.
All that being said, I am terrified about out-of-warranty repair costs. When they happen (and they will happen if the reliability on here is any indication, which I think it is), they are going to be expensive, even if you have the extended warranty (read the fine print, there is a deductible for each incident).
In closing, amazingly enough, no problems as of yet that have cause me to be stranded anywhere. Although the door handle issue forced several entries into the car via the trunk. I am slightly concerned that the whining sound is a precursor to something that could cause the car to be un-drivable, but the service center seems oddly unconcerned.
And here is the real kicker, I'm still on my 1st 12v battery! I know, right?
