We had a 2015 Model S P90D and replaced it with a Model S Plaid last August. While much improved over the earlier model, the Plaid's software has not been glitch-free. However, the software glitches I'm still experiencing with our Lucid Air Dream after seven months are of a magnitude I've not seen in any other car I've owned over the past decade.
This morning all the audio in the car was dead -- not just the music audio, but also the seatbelt warning bells and the turn signal sounds. Of course, as with many of these glitches, it was cured when the car reset. But, frankly, I'm getting really tired of driving so often without certain features until I either get where I'm going or find it convenient to pull over and do a reset. Every time I get in the car, I feel like I'm rolling to dice to see what software features come up on this roll.
The saving grace is that the car is the best driving and riding machine I've ever owned. But this constant software crap shoot is getting really, really, really old.
