Here are the facts: • Went to a movie • Parked outside in the parking lot • Tapped on keyfob once to lock car as I walked away • Car flashed yellow lights once in acknowledgement like it has always done • 29ºF outside, windy, clouds, snow flurries, no sun • Movie was 2+ hours long • I walk back to car • As I approach drivers side door, the handle autopresents, like normal • I reach for handle and notice it is WARM • I open door, car is very warm and toasty • I also notice the car is on, doesn't say "Car Off" • Seats warm • It's like the car has been on for two hours • I glanced at the battery -- thought, well, am I gonna see a huge drop? Nope. It did drop a little, but was close enough to where I would expect it to be after a short drive (~9mi round trip) with the heat on. Here is the question: What's going on? This has never happened before in 3.5 years of ownership (55k mi). Anyone ever seen anything like this? Is there a bug such that the car stays on for hours?
