Small question, what was your build date?(or delivery date) For now though, ill attempt to answer this:
For the steering wheel, foam or rather microfiber between the shaft and the wall seems to be the most widespread option, even though I believe lucid will resolve it soon along with that bad button issue.
Rear deck is pretty common, "Bobby" foam fix is recommended in this forum. I myself do not know how to do this.
For the seats, this should not be happening. However, I spotted one thing in that sentence that you shouldnt do, which is leather conditioner. This leather is highly sensitive, and lucid recommends only a cloth and a wipe.
Soft close is a known issue, and its really random.
