Same here on my DE with all sorts of key/fob issues but seems to be getting a little better with the latest update. However, still not reliable and I hope the phone key is in the works...that has been bulletproof on my Teslas.
Two issues I wonder if others have had:
1. Microphone volume very low. I am unable to use the in-car microphone as the other party says the volume is very, very low. As a result, I use my AirPods 100% of the time for in-car calls. The local Lucid tech has ordered replacement microphones, and we will see if that fixes the issue. I was able to demonstrate by calling the tech from inside the car while switching between the car microphones and my AirPods - the difference was notable. Anyone having a similar issue...maybe something to do with a SW setting for gain?
2. Creature comfort hangs. I have found that about 30% of the time, when I return to the car after enabling creature comfort for my dog, the screen refuses to go out of the creature comfort mode, and no buttons anywhere work. I have tried to reboot several times, and each time it returns to the creature comfort screen and is unresponsive. At this point, the car seems bricked. What has cleared the issue is simply opening the driver's door after I have been in the car and tried multiple reboots. It looks like the door being opened from the inside exits a hung creature comfort state. This is clearly a SW issue and should be addressed.
The car is absolutely fantastic to drive, and the DE with the large tires still has a great range compared to my Teslas. Love it. Just if some of the SW issues would stabilize and be addressed....
