1 year and ~11,000Km, and I've seen:
- 2x 400Volt power converter in the front blow
- 1x PEM fail
- 2x Fuses in the battery blow (1 caused by a 400Volt converter blow, and 1 caused by the PEM issue) - requires battery swap and a lot of work
- 1x VMS swap-out as it locked-up when extracting logs to USB
- 1x Windscreen wiper blade fail (metal bit came out and threatened to scrape the windscreen)
- 2x TPMS rear antenna replacement
- 1x Loose wing mirror
- Minor squeaks and rattles
Quite a list, and talking to other owners here in HK, it seems I have just been unlucky. Most of the above was in the first six months, and the last six months have been pretty ok. Maybe pu
That said, the 400volt converter is an issue out here in the high humidity of Hong Kong and that is something Tesla have been working on. I used to plug in and charge immediately upon returning home - now I have it set to charge at 4am to let the front dry out a bit before applying power. But, this is a concern as the summer is coming here and things are about to get very hot and very humid.
The Tesla service and support team are beyond praise. The last time a 400Volt converter blew, the head Ranger came out to my home late on a Saturday afternoon and had it swapped in 30 minutes or so. They've honored warranty on everything, without a fuss, and have come out to my office/home to deal with the issues - saving me the trip.
To follow up, the above list was as of 2012-04-19.
In the three and a half years since then... Nothing. Car has been working just fine. Shakes, rattles, and squeaks, of course, but other than that all the major components have been fine.
