So I'm sitting in the airport waiting lot, it's a little cold, heater on, and I noticed each time before the car fires up (automatically) I hear a little gear sound? It's not super loud, and only last about 1-2 seconds until the motor starts, then goes away. But interestingly, right before the gas motor shuts off, it also does the little gear sound ? Granted, that is not very noticeable because with the has motor running, it's harder to hear. Anyway, if a person didn't know this car, they might not even notice it. But I've slept in this car enough, I'm sure I would have noticed it at some point, and I really haven't ? Any of you ever heard this, or know what it is ???
