We have a new LRY with 4000 miles. Took ownership in March. We've only been in FSD Beta for a few weeks. Recently, while driving at night in FSD, we received alerts that the left then right cameras were obstructed and it kicked us out of FSD. Since then, whenever we drive at night, we cannot initiate FSD. The "steering wheel" will not illuminate on the screen and when we try to initiate by double clicking down on the stalk an error displays, "Cabin Camera is Covered," but there is nothing covering it. Called Tesla and was told that it sounded like a calibration issue and recommended we reboot the computer. Did that, but the problem remains. Tesla won't send out a remote service, so we're staring down an hour/half drive (one way) to the nearest service center. Very frustrating for such a new car. Anyone else experiencing this? Any troubleshooting ideas? Thanks in advance.
