...difficult/expensive to fix...
I drove my 2012 Model S for 6 years and 100,000 miles and did not have any problems with
1) Air suspension.
2) frameless windows.
3) Retractable hidden door handles.
It did have other replacements during its old age though:
1) Gen1 Mobile Connector (still worked but with signs of overheated points)
2) Re-manufactured MCU 17" screen and computer (still worked fine but with cosmetic bubbles)
3) Cabin heater (If I had to pay for it, I wouldn't replace it because I don't live in a snowy region)
I did not pay any additional cent on the repairs because I pre-paid the Extended Service Agreement.
But you are right: Tesla repairs are very expensive if I had to pay out of my pocket.
I have been driving my 2017 Mode X for the past 2 years and 25,000 miles and I have no problems with:
1) Air suspension.
2) frameless windows.
3) Falcon Wing Doors
All others totally with zero problems but it's not near 100,000 miles yet, so it's still premature to brag.
I have been driving my 2018 Mode X for the past 1 years and 8,000 miles and I have no problems with:
1) Coil regular (not air) suspension.
2) frameless windows.
All others totally with zero problems but it's not near 100,000 miles yet, so it's still premature to brag.
But if I have a choice, I would still want Air Suspension and some kind of automatic doors for my Model 3 (Model S has auto-presenting handles, Model X has the automatic opening and closing for driver door).
