Bit over a year for me owning my 2025 Air Touring. Day after I got it, drive system error, had to drive it to Millbrae service a couple days later as I could not get anyone to call me back to schedule after numerous attempts. 10 days later it was back and fixed. Few weeks after that got another drive system warning but before I could take it in someone hit me and dislodged most of the front bumper.
I drove it home, the other car was totaled (Air is literally a tank!). Couple months later ($35K, insurance handled) I got it back. Since then it's been "near" perfect. Not flawless. I have had the audio cut out or get garbled, screens go black or reboot unexpectedly, PAAK delays, etc. Except for PAAK performance/inconsistencies those things only happened a very few times and have, generally, completely gone away for quite some time with OTA's.
Since two updates ago, PAAK got a lot better. With the Latest update it's almost perfect now and the car unlocks at a substantially increased range (they really fixed something with it). Maybe 1 out of 20 times there is a delay, probably 10 seconds max (some of which is likely phone waking Bluetooth up). Still irritating that since my phone is not far enough away from the car where it resides in my house, it turns off hands free unlock and I often have to press the handle when I go into my garage, but I've become accustomed to that behavior.
So yep, would buy again (or Gravity, or upcoming midsize when the lease comes due).
Tesla is out (though my 2018 Model S 100D I owned for 6 years prior had essentially zero problems and drove where I pointed it. Ride was not as good, wind noise at elevated speeds was not great, and while the Air absolutely drives a lot better, I felt similarities between the S and the AIr. My Model S handled great, I could go into any corner, almost as fast as as I wanted, and it was glued to the road. That said, the AIr is a step up in everything, and often by a wide margin. Those that try to paint a massive differences do not jibe with my experience at all, maybe I got lucky. That said, never Tesla again (variety of reasons), Air is much more efficient (for me - even with spirited driving), plus the AIr is absolutely a vastly more premium experience.
Flawless? Nope, no way. Still enjoy the AIr more than any other car I have had.
