2017 Forester 2.51 Tourin
I almost did that a few years ago when my 2017 Touring was nearly new & drove down to Tubac, AZ. Had a friend in the car with me, so we were talking & also I parked next to refrigerated truck that was noisily running right next to me delivering stuff to a restaurant. We both got out & I couldn't figure out why the car wouldn't let me lock it with the touch place on the outside door handle, it kept beeping at me. Got back in the car after trying multiple times to lock it & glanced at the tachometer & noticed it wasn't where it would be if the car was turned off, so pressed the start button to turn off the car. Not sure if I'd do the same if I was in a quiet surroundings, I can usually hear it running. The only time I leave the car unlocked when I'm not in it is parked in my garage, I just always lock it out of habit when I get out.
