I reverse into my garage so that my FWDs are beyond the overhead garage door opener allowing the to open freely while inside. I have single garage doors into a multiple bay garage so the openings are relatively narrow and challenging to navigate. Sometimes it takes several attempts backing-in then pulling-out to get this wide beast lined up properly inside the garage. I've gotten fairly good at it over the past few weeks, but sometimes I still struggle if I'm tired or careless. Late last week I was significantly off on my first backing-in attempt, so I needed to pull all the way out of the garage to realign. On my second attempt I reversed directly into a closing garage door! Bang! Oh crap! Not good! After some serious head banging and sole searching I realized that the 20ft auto open/close Homelink distance must be measured from the front of the car where the RF transmitter is located. So, if you back into your garage, then slowly pull out about 3.5ft past your back bumper (car is 16.5ft long) the car thinks you're on your way out and closes the garage door behind you. There is no audio alarm if you decide to reverse back into the garage for a second attempt and aren't paying attention to the Homelink notification top of screen! ..especially if your neighbor's lawn is being mowed a few yards away and you can't hear the garage door closing, like in my case. I'm fairly certain others will run into this issue if they reverse into their garages and are anything like me about the position of their cars inside the garage. The SW should be smart enough to differentiate between pulling in forwards or backwards into a garage and adjust the 20ft distance accordingly - perhaps 30ft from the middle of the car (simulated distance). Or at minimum, allow the distance variable to be user defined similar to the Summon settings. Maybe even sound an alarm if the car changes directions within a minute of Homelink activation. I logged a ticket with Tesla in hopes of alerting them to this use-case and hope this note helps others avoid an embarrassing situation and a potentially costly repair.
