I have a fairly early car (#154), and it did require a few hardware fixes (license plate mount, trunk lid adjustment, weather strip replacement, AC fan grinding). But now, over seven months after delivery, the hardware on the car is completely nailed down (except for the driver's floor mat, which won't stay attached to its velcro tabs). We are about to turn 10,000 miles on the car, and it remains squeak, creak, and leak free.
Personally, between improvements at the factory and Lucid's prompt mobile repair service, I would have no qualms about the hardware on a recent build.
The software . . . another story.
