I think I'm getting through this in part because of my experience with owning an early Air (December 2021 delivery). The first ten months with the UX 1.0 UI suite was a nightmare, but once UX 2.0 came along and Lucid started issuing rapid-fire OTA updates, the issues began to die away fairly quickly. For most of the past couple of years the car has been relatively problem-free, leaving me to enjoy what a great driving machine it is without recurrent torment.
Also, the Air, like the Gravity, had to have a new rear drive unit installed (along with a new battery pack). But the service experience was so seamless, if a bit lengthy, that the drive unit failure with the Gravity didn't completely unnerve me. (We also had to have a rear drive unit and battery pack replaced in our 2015 Tesla Model S, so it's a rodeo I've been to three times now with EVs.)
As near as I can tell, the automotive engineering end of the Gravity and its structural solidity give the Gravity seriously good bones. If the software improvements travel the same trajectory as the Air's, then I think we'll end up with two truly superior vehicles.
What most annoys me, though, is that Lucid did no better with the introductory software of the Gravity than with the Air but is still continuing to put it into customers' hands. And my fear is they will do the same thing with the Earth mid-size, which might be the death knell of the company.
