The Air, now 5 years on, is reliable. That’s a fact.
What's reliable for one owner may not be reliable for another.
@borski and I both have Gravity Dream Editions. His -- produced earlier than ours -- has been relatively problem-free. One of ours has had to have the HUD unit, the steering wheel, and the front drive unit replaced. And on the only two out-of-state trips we have done in it, we returned home in a rental car both times as the issue with its front drive unit has now shown up in the rear drive unit.
We have two Gravity Dream Editions. The other one has already had the rear hatch latch replaced, and it still does not operate reliabiy. Also, both have a range of software issues, but they differ from day to day and also between the two cars.
As for our Airs, one of them had to have a rear drive unit and a battery pack replaced. It has been through four frunk lid repairs to the point that we no longer risk using the frunk. The driver door handle mechanism has been replaced.
So to say than an entire model run of a car is incontestably reliable is an over-generalization.
Fenske loved the Air when he first test drove it, to the point that he bought one as his personal car. Unfortunately, the one he bought was enough plagued by issues that he chose to get rid of it.
As someone who has bought 5 Lucids (2 Airs and 3 Gravities) -- and who still loves the brand for other reasons than reliability -- I am not at all surprised by his experience. An individual car can be reliable -- and most Lucids probably are, in fact -- but to suggest that an entire Lucid model run is totally reliable is a bit of a stretch.
