Issue with water entry into rear taillight, on bootlid side. They will change the unit next week. I had this previously on the right side. Was told a seal had given way. My car, a September 2014 build, 44000 odd km, is now virtually new again. New MCU, new drive unit, new taillights, Unplugged performance front fascia to match facelift, new tyres, suspension and steering retorqued. Service in Sydney Australia has been great, but overall reliability, not so much. I always get a Tesla loaner so that is never an issue.
Same vintage, built August 2014, surprisingly similar issues:
- water in hatch, tail light seal - so I got 2x new tail lights, new seals, and new chrome trim piece
- new MCU center stack (complete), the GPS stopped working, voice commands stopped working... I opted for LTE upgrade at that time
- new D/U... milling so replaced at around 45k km, no recurrence since
but also
- 4 x door handles serviced for presenting but pulling would not open, we think the cold weather makes wires brittle, they break when flexed
- HPWC charge handle HOT, got whole HPWC replaced under car warranty period (because purchased at same time with car)
..and a bunch of little niggly stuff with trim, squeaks, sunroof alignment / fail to open, etc... all easily addressed. I busted the hinges on the globebox by shutting it with a pen fallen into the gap along the bottom.. so I bodged something there that is still holding up well and you'd never know it was broken.
At 100,000 km front upper ball joint on passenger side sloppy, so I just replaced both front upper A-arms (myself!). For such a heavy car, I expect higher than average replacement of suspension parts. But the rest of it seems to be holding up, and no issues with air suspension system (knock on wood!).
Some people on the forum have access to Tesla manuals and can be very helpful with things like, torque values for bolt tightening...
And I notice other niggly stuff now.. but not worth calling... some LEDs around the charge port burned out / quit showing
New windshield $1000 all said and done... on my nickel.
Because I'm off warranty, and (gulp!) no extended chosen, I probably won't ever bother with minor niggly stuff that I can't fix myself, just "let it be". For example, if folding mirrors stop folding - I'm OK with them becoming fixed position mirrors and I'll pull the power to them. But I'm a handy guy and not afraid to roll up my sleeves to work on cars. And Tesla is willing to sell me parts. And they're not crazy priced parts, pretty reasonable as compared with other automakers.
If I had taken extended warranty, I'm now at 110k km so that's about 38% through it but I've spent nothing in this period that would have been covered by it.. so tucking those savings away for when something does go wrong or needs replacing (like the windshield). So far, car has never been not driveable... even with all its fixes and glitches and annoyances.. like D/U milling sounds. I drove 2000km to get that fixed at nearest SC (at the time) for an afternoon D/U swap.
