I'll share my keyfob experience since I don't think I came across anyone having one of my issues.
I accepted delivery of my Gravity GT on 9/30. Surprising is that I got 2 keyfobs and 2 key card.
Key fob detection issues. Both came with less than perfect battery levels (2.948V and 2.935V). One of the key fobs (back in the Lucid Service Center) would freak out the car as it would send alert after alert saying no key detected. I had one new battery so I replaced it for one of the key fobs. It is possible that this issue was resolved by replacing the battery in the key fob and installing 3.3.2 update as I didn't see this issue in the fob with new battery. But after occupying the car for long period of time without going into the Drive gear, the car wouldn't detect the key fob (the one with new battery). I had to shake it for good 10+ seconds for it to eventually detect it.
No reaction or very delayed reaction to button presses on the either of two key fobs. New battery didn't help. Sometimes I press unlock and it will unlock doors 3-5 seconds later. Many times it won't do anything. The best thing for me is keep pressing lock/unlock button repeatedly until it works. Sometimes it will work after 3 presses, but often I had to press it 10-20 times to register. Holding the button (at least the lock one) is not an option because it triggers the panic alarm (often with 5 seconds delay) that I have trouble disabling because it again doesn't react to my unlock button presses so it screams at me for extended period of time
- I updated the car to version 3.3.2, but that didn't help. I hard rebooted the car (20+s holding break pedal, Cancel, and Microphone buttons) with no improvement. I restarted both fobs (remove battery foe 30s, hold unlock button down, put battery back in, release unlock button), but that also didn't help.
- During delivery appointment I asked whether fobs have the newest firmware (required for 3.3.1), but I was just told the issue with fobs was fixed...
- Good news is that key cards seems to work consistently. Phone app wakes up the car fairly quickly and consistently unlocks and locks the car.
- The fob with new battery was consistently detected, because I had no trouble opening and closing the doors by pressing driver's handle.
Within few days I started talking with service center and eventually scheduled an appointment for the end of this month as I have a few other mechanical issues they need to fix (like stuck privacy shade in one door and frunk failing to open every now and then). They recommended to reset the fob (which I already tried). But I decided to try it again and funny enough the issue was resolved. Car was responding to all fob presses. I took 2nd keyfob, but I didn't restart it and it worked perfectly too, so I don't think the issue was with the fob but with the car and probably combination of a few hard reboots and car going to sleep resolved it.
It was perfect until yesterday. The issue came back. 10-20 pressed to get the car to lock or unlock. Both fobs are affected. Tried hard reboot like 8 times in 2 days (I also started seeing many DreamDrive unavailable, sensors blocked etc. errors). Tried key fob restarts, on the fob I keep using, 4+ times now. Issue persist. Even after leaving the car to let it sleep for the night didn't help as I had the issues all day today. Also, it has issues detecting the key now. I was shaking the key for good minute and then gave up and successfully used the key car. Funny is that it happened when I was going to drop off my team after a lunch... But I conditioned them beforehand and told them the car is buggy so we just all laughed at that.
This is the most frustrating issue I have with the car. Just standing and pressing the keys 20 times for the car to register. I'll probably go back to pressing driver's door handle since it worked in the past.
Oh, I checked the battery in "my" keyfob today. It was 3.009V, so it is still (should be) fine. But surprised that after just 2 weeks the voltage dropped from 3.24V to 3.009V. I have automatic lock and unlock disabled and I keep the fobs far from the car in faraday pouch (that I confirmed works with those fobs, they block UWB just fine) in a place that is rarely "moved" so the fobs should stay asleep for long period of times.
I'm really baffled and I'm not sure what is the problem. Is it software? Is it hardware?
