My 2020 Tesla x LR PLus has this issue.
I cannot open left Falcon door fully. It showed false obstacle detection everywere I parked, in spacious locations.
What I did:
1. Pressed button on back (second row) to open it fully, then closed it. As in internet, people said it calibrated Falcon door. THIS DID NOT WORK.
2. I rebooted severl times, DID NOT WORK.
3. Cleaned Falcon door, DID NOT WORK.
Does anyone have any suggestion?
