What's the sound from the engine compartment when you open the door
I noticed a humming type sound from the engine compartment whenever I remotely unlock the doors or open a door. Anyone know what this sound is?

I too have noticed that humming rumbling noise from time to time while driving and almost always when first getting into the car in the morning. It is a bit annoying.
I also notice that when driving in my office garage, up some ramps going very slowly that the car seems to hesitate a bit. It seems like the tach shows the engine slowing down around 500 and then it revs up making a strange sound like recovering from a stall. I only notice this when going very slowly - perhaps it is gear searching?
