2016 Model X. Last summer I noticed that if sun hitting on the falcon door, it thinks there is an obstacle and shows red. It is interesting that it happens to either door as long as there is sun exposure. I had a similar problem when the car was only a year old and it was happening always on the right side door. At the time the ranger said the heat from the sun makes the mount to sag and causing the sensor error. A couple of weeks ago, I took her to the service, they said they replaced both of the sensors. We just happened to have sun again today, and it was showing as if there is an obstacle. I’ll need to reopen the ticket. Did this happen to anyone?
