I can call BS on the BS callers. In my case, 2016 X, the drivers door opened on its own a few times. It was always very unpredictable about opening distance or closing as it should. When people at work told me my door would open and close itself without anyone around and dinged their truck I thought they were messing with me. Frequently they’d tell me it’s on fire, so why would I believe them?
At a hotel Parking lot during a stay at the beach, fob very far away back in the room, I saw it. The drivers door opened, tapped the next car over, a few times and then stayed open. I took pictures, wrote down the time/location and service center saw some log anomaly in the body control module. Once they replaced that, my doors never opened on their own again unexpectedly.
Now As for the distance issue, my issues were related to the FWD sensor being loose and temperature swings. several visits Over 3 years to the SC telling me it doesn’t happen, not possible, can’t reproduce issues, or this is common, expect it once or twice, etc. I kept asking. once they did find it was lose and reapplied sticky tape. Still had issues with the FWD phantom obstacles that were magically not reproduceible at the SC. 3 months ago I was just ready to sell the Possessed car. And because “all Tesla’s do this every now and then” as they said, I was looking at other car brands that had working doors. My FWD issues were daily, sometimes multiple times a day. I took lots of pictures, time stamps, etc. they finally worked on the door sensor just to prove to me it was fine. They added extra sound deadening patches, foil backing, reglued the tripod sensor mounts, etc. it’s been great ever since.
the sensors and tripod are cheap parts. The car also does not log resonance echo. They only log complete failures. Could be as simple as some sticky tape or sound deadening patches to solve your issue. Also, bad LED or flourescent lights emit ultrasonic sounds that can slightly cause the sensor to misjudge calibration. There is a known issue with hot temperatures expanding contracting metal, plastic parts. That microscopic heat induced gap can cause resonance echo. The doors recalibrate every close I’m told. If the sensors are off slightly at calibration then later change position, they can give a bad reading. So don’t let people say it can’t be fixed.
