I've had a series of issues with my recently purchased Model X. These have included several relating to door function: ALREADY FIXED: - Auto present not working (apparently they forgot to install a "module" at the factory). - Passenger door rattle and display intermittently showed "passenger door open" - both apparently due to a faulty latch - the latch was replaced. CURRENT / ONGOING PROBLEMS: - Further annoying rattle associated with passenger side FWD. - Yesterday the display kept flashing the "close all" button on and off (with all doors closed). - A few days ago, when the passenger door was opened it swung and hit the car parked next to me - thankfully no damage done. My questions for this post concern the last one on the list. 1) My understanding is that all doors (front and back) should open WITHOUT hitting an adjacent car. Am I correct that this is the intent? What are others' real-world experiences? 2) If I stand in front of any of the doors and open then, they will ALL open into me (with some force) before stopping. But I've read that this is typical and the sensors only detect "hard" surfaces like another car. So how can I test the function without risking damage to another vehicle (or my own)?
