Ever since the last update, I have been having issues with my 2014 Model S not powering off when I exit the vehicle and leave. Everything stays on. The only way it will power off is if I open and close the drivers door 2 or 3 times. I can also go into the safety settings and power off the vehicle before exiting. Those 2 options are obviously not ideal. Has anyone else had this issue? I've heard some people say it could be the seat sensor. Since my vehicle is out of warranty, I'm trying to avoid a costly bottom seat replacement. It's just strange it coincided with the software update.
