I also posted this in tesla forum so please excuse the duplication for those who read both. I have a 90D delivered in dec 2016. Overall I am very pleased and happy but have one recurring issue that SC team can't seem to figure out. Sporadically when I exit the car and walk away the driver door won't close and the car doesn't shut down properly. The settings are correct for this to happen in controls/settings area. Sometimes it's fine and sometimes not. I can't seem to find any pattern. My setting is also for headlights to go off on exit. The only thing I noticed is that when I exit and lights don't go off then the door doesn't shut when I walk away and the car doesn't shut down. If I walk away the door stays open, radio on, lights on etc. If I go back and press the door handle to close the door then door shuts, car doesn't lock, radio stays on and lights on. I kept a record of all the times it did this, about 8 times in a month and emailed the dates and times to SC and they reviewed the logs the said they couldn't find anything wrong. They suggested I bring it and leave it for a few days. It's annoying to do that and I honestly expect they won't figure it out so I am asking of anyone has experience with this or knows of a solution.
