I’ve had a number of issues with mine including replacement of AC unit, squeaky suspension, issues with autopilot requiring camera replacement.
Off the top of my head, the issues I've had with my Model X post-warranty include:
- Driver door no longer opening
- Noise when turning the wheel, which turned out to be grit under the bash plate, although they charged me £1,200 to replace something else that didn't fix it
- Heating failing, needing replacement
- Steering becoming stiff (quoted £300 to fix, but sorted it myself with a jack and a boatload of WD40)
- Horn not working
- Turn signals not working
- eMMC replacement
- Falcon wing doors squeaking
- Falcon wing doors wearing off the paint
- Loose panels rattling when music is on
- Keyfobs not identifying the correct user (never got fixed)
